The preamplifier is now ready for action.THE CONCEPTThe 808 MK5is a unique preamplification system. This is true not only in reference to its most advanced electronic technology and highest quality manufacturing but also with regard to its design. Its wide-ranging operational possibilities have made it the standard of reference in preamplification and the work horse for many audio developers and audio magazines worldwide.The 808 MK5 is a modular design. The system consists of· The basic unit· The input modules (maximum of six in any configuration – minimum of one necessary)· The output modules (two possible – one necessary)· Unused mounting slots are protected by cover plates· The SYM OUT output modules for balanced operation (maximum of two possible)· Modular technology turns the 808 MK5 into a dynamic system· From a minimal configuration it may be expanded step by step· It can be adapted to the changing requirements of its owner at any time· Individual modules can be sent in for modification while the system remains with the owner· Technological advances can be incorporated by modifying or exchanging modules;hence the 808 MK5 maintains its technological edge and its resale value over a very long timeTechnical specifications such as signal-to-noise ratio, total harmonic distortion and intermodulation are at the theoretical limits. The owner may rest assured that we have incorporated any presently known advance. We guarantee that the deviation of technical data from one unit to the next is less than one per cent.A short explanation of the nomenclature of the 808 MK5:The design of the original system was concluded in August of 1980 (=80/8). Since then, we have kept the 808 at the edge of technological advance by incorporation the results of our research and deve-lopment into it. The present fifth incarnation (= Mark 5) represents the leading edge of preamplifier design today. The jump from MK3 to MK5 signifies on the one hand the major advances that were incorporated into the MK5. It also takes account of sensibilities in the Asian market where 4 is an unlucky number.Major advances of the MK5 versus its predecessor MK3 XLR:· Remote control option not only for input selection but also for volume control.· A display showing the selected input as well as the volume setting.· Six additional AUX inputs.· Input and output for TAPE 1 are balanced.· Major improvements to the power supply.· The control circuits of the supply voltage have been improved and are now located directly at the transformer and the filter capacitors in the external housing. There is an additional filter stage for the supply voltage in the preamplifier.· Internal wiring has been done exclusively with our proprietary BURMESTER SILVER cable.· The PHONO MC module has been totally re-designed and can now be switched between balanced and unbalanced operation. In addition, dip switches on top of the module make the mating of the system with a wide range of phono cartridges easy.Why a balanced signal path?In conventional stereo systems the signal flows back and forth through different (asymmetrical or unbalanced) paths: The negative portion makes its way through the shielding (mass) of the cable and is, therefore, prone to modulation by transformer hum, radio interference and other electrical noise. Furthermore, the signals are very small and are thus easily influenced by paths that vary in material, length or diameter.By contrast, in a balanced design both signal carrying paths are identical (symmetrical). The surroun-ding shielding for grounding the cable is completely separated from the signal path. Hum and inter-modulation are strongly reduced and identical conditions for both paths ensure that even the smallest signals remain undisturbed. However, in addition to a more complex internal layout of the components this requires three- instead of two-pin plugs and terminals as well special cable. We have developed our interconnects BURMESTER LILA and BURMESTER SILVER for this application. It is manufactured exclusively for us.Balanced interconnections have been the rule in music studios for a long time. However, studio technology only uses balanced transformer stages with amplification circuits that remain unbalanced. This has distinct disadvantages which we avoid by carrying the balanced design into the first preamplification stage.For a better understanding of the functioning and the design of the 808 MK5 explained on the following pages, please also refer to ”THE SYSTEM” and ”THE FLOW CHART”.THE BASIC UNITThe basic unit consists of the following functions and features:· all controls and toggle switches· ten mounting slots for input/output modules· two volume control knobs· display (switchable)· digital level display/level control· tape loop· input terminals· output terminals· IR receiverThe necessary amplification circuits are part of the modules and the power supply is located in an external housing.Controls and toggle switchesMounting slots for the modules CAUTION:Volume controls The displayLevel indicator/ level control The desired input module can be selected with the S ELECTOR knob (3). The input signal of the selected module is always available at both output modules.The toggle switch MONITOR/SOURCE (4)allows a comparison between the source signal and the recorded signal while taping. A direct comparison between the recorded signals on two separate tape recorders can be made by throwing the toggle switch MONITOR 1/MONITOR 2 (5).The switches OUTPUT 1 (20)and OUTPUT 2 (21)determine, which output module feeds its signal to the output terminals, in other words, which of the connected power amps or active speakers the preamp will drive. This makes a direct comparison between various power amps/active speakers possible.Switches for sources, tape loop and output are not in the signal path but activate via a control voltage relays in the modules or in the basic unit. These relays then do the switching. The rationale for this rather involved design is to shorten the internal signal paths to the technically achievable minimum.The basic unit offers a total of ten mounting slots for modules:· six for input modules· two for output modules·two for S YM OUT modules which are necessary to upgrade the modules OUTPUT1 and 2 for balanced operation (see also the flow chart).Never plug an output module into an input slot and vice versa!The two VOLUME controls (6)and (7)adjust the volume of the two modules OUTPUT1 and OUT-PUT2, as is customary of both channels simultaneously. However, any imbalance between left and right channel can be adjusted with the level controls (12)and (13)on top of the input modules. Also, the level controls are not those widely used potentiometers with metal loops wiping over an array of resistors but controls with self-cleaning silver contacts which switch discrete, close-tolerance resistors according to their division ratio.This guarantees identical level of both channels down to the smallest volume. Any semiconductor effect known from potentiometers has been excluded and the corrosion resistance has been greatly improved.When switching the volume, a “clicking“ sound may be heard through the loudspeakers. This is nor-mal and no need for concern.The display (9)indicates which signal source has been switched to the output modules.Additionally, the right side of the display shows the selected volume (0 – 60) of the remote-controlled volume selector if the SELECTOR knob (3)has been set to REMOTE. Display switch (10) switches the display on or off. Note that the unit reacts with a slight delay when this switch is thrown. If settings of the 808 MK5are changed with controls (3), (4) or(5)or a remote signal is sent while the display has been switched off, it will illuminate briefly to acknowledge the change in the settings.The digital level display (22)makes it possible to adjust the input modules to an identical level and to perfectly balance the channels. It is calibrated in volts and shows the output voltage of the input module which has been selected with the SELECTOR knob (3). The level display selector switch (24) toggles between left and right channel; the level display switch (23)toggles switches the display on or off.Adjusting a phono cartridge:· Connect the turntable with the 808 MK5· Play an LP with a 1 kHz sinusoidal signal and a modulation of 5 cm/s to 10 cm/s· Use the level controls (12)and (13)of the selected phono module to adjust both channels, one after the other, to an identical DISPLAYreadout (such as 1.0 V)Input terminals Output terminals System remote Adjusting a tape recorder:· Connect right input of the tape recorder with a CD player containing a test CD with a 1 kHz sinusoidal signal· Set tape recorder to ”record” and ”pause” and adjust recording level to 0 dB. Record test signal · Repeat procedure for the left channel·Rewind tape and play back through the 808 MK5. Adjust both channels of the selected tape input module to an identical DISPLAY readout (1.0 V) using the level controls (12)and (13)Adjusting a CD player:· Put test CD into the player· Play 1 kHz/0dB sinusoidal signal· Adjust both channels of the selected CD input module one after the other to an identical DISPLAY readout (1.0 V) using level controls (12)and (13)Adjusting a tuner:· Unfortunately FM stations no longer broadcast test signals. As an alternative we recommend using the static noise between two stations (if the tuner has a switchable muting function) and proceed according to the last step of the phono input adjustment.The inputs PHONO (32), CD (33), TUNER (34)and TAPE 1 (35)are XLR terminals. They may also be operated as unbalanced inputs by using adapter plugs (XLR-RCA). Also, the dip switches on the circuit board of the modules must be reset to unbalanced operation.The PHONO INPUT(32)in the upper terminal array offers two RCA terminals (25)in parallel. They can be used for unbalanced operation or for the supplied phono load plugs to adjust for different cartrid-ge impedances. The upper terminal array also offers six AUX INPUTS (27)and a TAPE 2 INPUT (28) for unbalanced operation.The inputs AUX 2 to AUX 6 are only operable in the remote modus and can be switched by repeatedly pressing the AUX button on the remote control. Setting the SELECTOR knob (3)to AUX only activa-tes the AUX 1 input.The outputs TAPE OUT 1 bal. (36)and TAPE OUT 2 unbal. (29)are designed to connect to tape recorders and are driven by a tape loop stage in the basic unit. The output impedance has been set very low. The output voltage is dependent upon the level set with the level control on the selected input module; it is always half of the value shown in the level display.Power amplifiers or active speaker systems are connected to the terminals OUTPUT 1 unbal. (30)and bal. (37) or OUTPUT 2 unbal. (31)and bal. (38)respectively. These outputs are driven by the output modules OUTPUT 1 (14)and OUTPUT 2 (15)in unbalanced and additionally by the SYM OUT modules in balanced operation. Their volume is adjusted with the VOLUME knobs OUTPUT 1 (6)and OUTPUT 2 (7); they can be switched on and off with the switch (20)on OUTPUT1 or switch (21)on OUTPUT2 res-pectively. Headphones with an input impedance of >100 ohms may connected directly to output ter-minals OUTPUT1 or OUTPUT2.When the basic unit is switched on and the OUTPUT switches (20)and (21)have also been set to on, the terminals REM OUT 1 (39)and REM OUT 2 (40)provide a control voltage to switch power amplifiers or active speakers from stand-by to on – provided they are designed for this feature.The optional SYSTEM REMOTE CONTROL can control all components of our REFERENCE LINE, TOP LINE and CLASSIC LINE. The system remote controls all functions of the SELECTOR knob (3)as well as volume and thus enables you to compare various signal sources without leaving your listening position. For remote operation of the 808 MK5, the SELECTOR knob (3)must be set to REMOTE.If the 808 Mk5 has been set to remote control the following must be observed:· The remote-controlled volume adjustment affects both, OUTPUT 1 and OUTPUT 2 because theremote volume controller is connected in series with VOLUME controls (6)and (7)· In general, the maximum level to which the remote can set the volume depends on the volume levelpre-set by the VOLUME knob. We recommend position 12 and use the remote to lower the volume.· The AUX inputs 1 – 6 can be called up in sequence by repeatedly pressing the AUX button on theremote control.Maximum range is achieved by pointing the hand-held remote at the IR receiver (8).Before switching the 808s REMOTE function on or off, always lower the volume with the VOLUMEknob (6) and (7) to zero.THE INPUT MODULESEvery input module is a complete preamplifier which has been optimized for a specific signalsource. It has its own level controls for each channel. We only use highest-quality controls with· ceramic body,· corrosion protection by hermetical encasing,· Cermet resistors in the control range,· Metal-plated bypass of the resistors at both end of the control range which means that in thesepositions the level controls function as switches and no longer as potentiometers.The two level controls of each input module are measured by us and selected in pairs with a guaran-teed impedance tolerance of <1%. The level controls do not have the task to adjust for tolerances inthe electronic circuitry of the 808 MK5. They are designed to correct possible channel imbalances insignal sources and to adjust various signal sources to the same output level. Thus, while comparingvarious signal sources, you can switch from one to the other without jarring jumps in volume.Available input modulesAt present four different input modules are available:· PHONO MM· PHONO MC 2· LINEAR· LO-LINEPhono modules are available as unbalanced PHONO MM (Moving Magnet) as well as PHONO MC 2(Moving Coil) which is switchable between unbalanced and balanced operation.Linear modules with amplification are designed for all line-level sources such as TUNER, CD, TAPE 1,TAPE 2 or AUX. These denominations are engraved on the cover plates of these modules (customengravings optional). The module LO-LINE (without amplification but with level controls) is designedonly for unbalanced signal sources with an output voltage of >1Volt and an output impedance of <200ohms.All line-level modules with amplification can be configurated for balanced or unbalanced operation bytwo dip switches on the circuit board of the modules. To do this, remove the four screws that hold thecover plate and pull the module carefully out of its mounting slot by the level controls. The dip swit-ches are located directly above the plug connector. If they are switched to the left (dot is visible) themodule is configured for unbalanced operation. If they are switched to the right (dot is not visible) themodule has been configured for balanced operation. Please, make sure that both switches of onemodule are switched to the same position.CAUTION:Interconnects/mounting slotsTo connect balanced input modules requires special interconnects with two separate signal leads and a common shielding. For this we recommend - as for all interconnections of your stereo system – using our proprietary cable BURMES TER LILA3 or BURMES TER S ILVER. It is available in any custom length and with any plug combination and hook-up configuration, including a separate tonearm mass cable. Consult your dealer and our ACCESSORIES price list.Basically, any input module will function on any of the six mounting slots. However, you should keep the following in mind:· The phono module should located in the mounting slot PHONO 1 because it is the only one with parallel jacks for adapter plugs· All linear modules contain a tape loop but it is only functional in the mounting slots TAPE 1 and TAPE 2· The AUX module can be used in any of the six mounting slots but only in unbalanced operation. Since balanced operation is not possible the dip switches of the AUX module must be set to unbalanced. The level control of the AUX module affects all six AUX inputs· The TAPE 2 mounting slot is also designed for unbalanced operation only. The dip switches of this module, too, must be set to unbalanced operationAdapter plugs· XLR-RCA. If all AUX inputs (27)are used for unbalanced signal sources it is possible to connect unbalanced signal sources also to XLR terminals by using adapter plugs. In this case the dip switches of the respective input module must be set to unbalanced operation.THE OUTPUT MODULESAt the output section of the 808 MK5 we have exercised the same care as with the input section:· Maximum flexibility by using two separate output modules OUTPUT1 and OUTPUT2· Level controls with the same specification as those on the input modules; without changing the setting of the VOLUME knobs (6)and (7) the level controls can be used to eliminate channel imbalances and differences in volume of two separate power amplifiers / active speakers· The extremely low output impedance allows the connection even of long cable runs without deterioration in sound· Use of two separate balanced power amplifiers or active speakers by adding the SYM OUT modules You can operate the 808 MK5 with one or both output modules. The two available output modules are technologically identical and differ only in the engraving on the cover plate. Each of the two mounting slots OUTPUT 1 (14)and OUTPUT 2 (15)has its own VOLUME knob (6)and (7), its own SYM OUT module (16)and (17)and its own toggle switch (20)and (21).THE POWER SUPPLYThe power supply has its own external housing.The supply voltage of the MK5 is rectified, smoothed and stabilized already in the external power supply. This keeps the power-line frequency with its unavoidable alternating fields from interfering with the sensitive amplification stages. This reduces noise and hum from the power lines to an absolute minimum, comparable to battery power. An added advantage is that a move to an area with different line voltage requires only a new power supply while the 808 MK5 remains the same.The AC switch in the AC terminal (43)switches the power supply on. The control LED (44)lights green as long as the basic unit is switched off.。
Hi - Fi 音箱厂家至少有上百家,不过这其中能自己设计并生产扬声器单元的厂家却很少。
大部分厂家都是定做或购买扬声器名厂的单元再设计分频器和箱体。
最负盛名的扬声器单元厂家是丹拿( Dynaudio )、绅士宝( Scan-speak )、福柯( Focal )、傲的诗( Audax )、西雅士( Seas )、魔雷( Morel )、 ETON 和 JBL 。
此外, KEF , Diatone,B & W , Altec ,LPG , Visaton , Thiel , Elac , MB 等厂家也出产优秀的单元。
(一)挪威名厂 Seas (上)西雅士厂址在挪威首都奥斯陆附近。
建厂五十余年,亨誉全球,目前该厂共生产 55 个型号的单元,口径从 19mm 到 250mm ,很多厂家都乐于采用西雅士的单元,或委托其定做单元。
计有尊宝的旷世系列,雨后初晴( Harbeth ),贵族( ProAc ),世霸( Sonus Faber ),飞声( Audio Physic ),雅龙( Alon ),维也纳( Vienna ), Westlake , MBL , Audio Vector , Diapason 等等。
H149 ( 11F - GM )世霸的 Minima ,贵族的 Tablette III ,晋扬歌剧系列,阿里的波音 727 ,澳洲 AXIS 旗舰 LS-88 ,法国 Audio Vector 的 3a 这几对音箱都采用了 H149 这个单元。
H149 的优秀程度不言而喻。
H149 是西雅士精心制造的一款口径仅 110mm 的靓声小扬声器。
它采用轻质铝合金材料做音圈骨架,采用铜包铝做音圈绕线,且采用散热效果较佳的矩形绕线。
H149 的音圈直径是 26mm 。
采用超大直径的锶铁氧体磁路,锶铁氧体能胜任在低温下工作,且磁能积较大,不过成本高, H149 的磁通密度达到了12500 高斯以上。
教你看懂扬声器的构造图作为音箱最基本的组成部分,扬声器单元(简称单元)对于普通读者来说是既简单又复杂的。
为什么这么说呢?因为单元的工作原理似乎很简单,往复运动的振膜不停的振动,带动空气形成声波,似乎就这么简单。
不过本文也没有让您一下子就能肉眼辨别单元好坏的妙方,只能先为大家揭秘这么个看似简单的单元,内部究竟是个什么样,各部件有何功能等等。

锥形扬声器的特点及其内部组成:锥形扬声器是我们最常的扬声器类型,它的结构相对简单、容易生产,而且本身不需要大的空间,这些原因令其价格便宜,可以大量普及。
其次,这类扬声器可以做到性能优良,在中频段可以获得均匀的频率响应,因此能够满足大部分普通消费者的常规听感需求。
最后,这类扬声器已有几十年的发展史,而其工艺、材料也在不断改进,性能与时俱进,这也令这两款扬声器能够获得成为主流的持续的原动力。

教你看懂扬声器单元的各项数据2015/8/26 17:25:32 来源:艾维音响网[提要]今天,艾维音响网给大家介绍一下扬声器单元的一些主要参数。
艾维音响网今天,艾维音响网给大家介绍一下扬声器单元的一些主要参数。
以下面一款型号6寸半低音单元为例,它的参数表可以在商城找到。
以它的数据为例:第一部分是关于这个单元的特征的纯文字描述:这类单元是一种紧凑型短音圈单元,带有环形钕磁。
申请了专利的磁路提供了非常长的线性冲程,同时力系数很高。
上夹板设计成可以“引导”磁体附近后向气流的形状,同时由于铸铝盆架的设计非常开放,这个单元真正避免了声压缩。
接下来,就是所谓的"DriveHighlights"部分,也就是这个单元的亮点所在。
写的是“钕磁,短音圈磁路系统,特长线性冲程”。
第二部分就是参数表,放大看一下:参数中英对照:fs:谐振频率(单元自由场谐振频率,单元阻抗峰所在频率,此处电相位角为0度)Qms:机械品质因数(此处s代表扬声器单元Speaker,下同)Qes:电品质因数Qts:总品质因数BL:力系数(磁隙磁通密度B与位于磁隙中的音圈导线长度的乘积)Rms:机械力阻Mms:总振动质量(包含所推动的空气负载,不含空气负载的为Mmd)Cms:悬挂顺性(由折环与支片的顺性构成)Sd:有效振动面积Vas:等效容积Sensitivit:灵敏度在这个表中,所有的数据又分成了四个部分分别是电参数、T/S参数、额定功率、音圈和磁体参数。
1. 电参数在电参数中,首先是“nominalimpedance",即额定阻抗,或叫标称阻抗、名义阻抗。
什么意思呢?一般是指单元谐振峰后面(频率更高的方向)阻抗最低点的近似值。
网络配图本文我们研究的这个单元最低点大约在150赫兹处,数值大约是7.5ohm(下面写的Zmin就是),近似值就是8ohm了。
那如果是7.1ohm呢?还是标成8ohm。
大多数单元的额定阻抗不是8ohm,就是4ohm。
扬声器参数讲解1.RMSE-free:此为所测得的参数值反推阻抗曲线,并以此估之阻抗曲线和原测得之阻抗曲线作一误差平方和的计算,故此值愈大,表示所测得的参数愈不可靠,须重新检测测试程序及接法.2.Fs:即Fo,最低共振频率,这个参数决定了扬声器声音重现的低频界限,它决定于扬声器振动系统的等效质量和等效力顺,即Fs=(1/2)(MmsCms)-1/22.1增加边的硬度可提高Fs,增加弹波的硬度可提高Fs。
2.2增加等效振动质量,即增加边,胴体,音圈,弹波,中心胶,防尘盖和加大口径(即空气负载)的重量,均可降低Fs。
3.Re:线圈的直流阻抗,Re=*L/S:音圈导线的电阻率,L:音圈导线的长度,S:音圈导线的横截在积。
Zmax:扬声器阻抗曲线上的峰值阻抗Ro=Zmax/Re 4.Res:电气系统的等值电阻值。
Res=Zmax-Re=(Bl)2/Rms Rms:支撑系统的等效力阻。
4.1改变振动系统的力阻,如在管材,鼓纸和T铁上打孔或将弹波的材质改稀,或将含浸浓度降低,或增加鼓纸的刚性(将鼓纸纤维打短打细以压得更紧),或改软振动系统,盆架的窗口改大,可提高Res。
4.2增加BL值可提高Res(对Res影响最大)Rms为振动系统的力阻。
4.3随喇叭口径的增加而降低(增加了sd值),Rmr为幅射力阻,面积越大其值越大。
5.Qms:机械系统的阻尼系数。
Qms=o*Mms/Rms,Rms=(Bl)2/Res.5.1改变振动系统的力阻,如在管材,鼓纸和T铁上打孔或将弹波的材质改稀,或将含浸浓度降低,或增加的鼓纸的刚性(将鼓纸纤维打短打细以压得更紧),或改软振系统,盆架的窗口改大,可提高Qms。
5.2增加等效振动质量,即增加边,胴体,音圈,弹波,中心胶,防尘盖和加大口径(即空气负载)的重量,均可提高Qms.5.3改变音圈管材材质(Kapton比aluminum高,til比kapton高)5.4增加喇叭的Fs值可提高Qms。
Hi - Fi 音箱厂家至少有上百家,不过这其中能自己设计并生产扬声器单元的厂家却很少。
大部分厂家都是定做或购买扬声器名厂的单元再设计分频器和箱体。
最负盛名的扬声器单元厂家是丹拿( Dynaudio )、绅士宝( Scan-speak )、福柯( Focal )、傲的诗( Audax )、西雅士( Seas )、魔雷( Morel )、 ETON 和 JBL 。
此外, KEF , Diatone,B & W , Altec ,LPG , Visaton , Thiel , Elac , MB 等厂家也出产优秀的单元。
(一)挪威名厂 Seas (上)西雅士厂址在挪威首都奥斯陆附近。
建厂五十余年,亨誉全球,目前该厂共生产 55 个型号的单元,口径从 19mm 到 250mm ,很多厂家都乐于采用西雅士的单元,或委托其定做单元。
计有尊宝的旷世系列,雨后初晴( Harbeth ),贵族( ProAc ),世霸( Sonus Faber ),飞声( Audio Physic ),雅龙( Alon ),维也纳( Vienna ), Westlake , MBL , Audio Vector , Diapason 等等。
H149 ( 11F - GM )世霸的 Minima ,贵族的 Tablette III ,晋扬歌剧系列,阿里的波音 727 ,澳洲 AXIS 旗舰 LS-88 ,法国 Audio Vector 的 3a 这几对音箱都采用了 H149 这个单元。
H149 的优秀程度不言而喻。
H149 是西雅士精心制造的一款口径仅 110mm 的靓声小扬声器。
它采用轻质铝合金材料做音圈骨架,采用铜包铝做音圈绕线,且采用散热效果较佳的矩形绕线。
H149 的音圈直径是 26mm 。
采用超大直径的锶铁氧体磁路,锶铁氧体能胜任在低温下工作,且磁能积较大,不过成本高, H149 的磁通密度达到了12500 高斯以上。
电声基础知识来源:网络首先,我们来谈谈如何认识一个喇叭单元,这是我们每个生产厂家、每个扬声器系统设计人员要面对的一个最基本而又是最重要的问题。
根据我国目前的生产和工程设计的实际情况来看,可以从以下六个方面的客观物理特性来认识喇叭单元。
(注:主观听感是认识喇叭单元的另一种重要方法,随着科学技术的进步,客观物理特性的描述与主观听感愈来愈趋于一致。
也就是说,随着科学技术的发展,我们将能够用客观物理特性的描述来表达主观听音的心理感受。
)一、T/S参数T/S参数是由THIELE和SMALL先生首先提出的扬声器系统数学模型的基本参数。
T/S参数在扬声器系统设计的指导作用已经被生产厂家、工程设计人员所普遍接受,在几乎所有常见的电声测试系统、扬声器系统设计软件上得到支持。
T/S参数由小信号参数和大信号参数组成。
小信号参数包括四个基本参数:1.Fs为扬声器单元的谐振频率。
2.Vas为扬声器单元的等效容积。
3.Qes为扬声器单元的电Q值。
4.Qms为扬声器单元的机械Q值。
大信号参数包括两个基本参数:1.Pe(max)为扬声器单元的散热能力所确定的最大功率额定值。
2.Vd为扬声器单元振膜在最大振幅时所推动的体积。
上述参数主要是向我们提供了模拟和设计喇叭单元在谐振频率附近的频率响应特性的依据,通过合理地优化箱体结构参数,从而达到我们所期望的扬声器系统频率响应,用以满足不同的使用场合和不同的使用要求。
从某种意义上讲,T/S参数没有更好,只有更合理和更合适。
例如Fs/Qts的比值在那个范围适合那一类声箱系统,Vas如何取值更为合理等。
T/S参数最重要的是它们如何搭配和优化。
在这里需要指出的是,T/S参数的实际测量误差应引起足够的重视。
T/S参数误差过大,会导致在系统设计的过程中的理论值与实际值偏离过大,甚至失去T/S参数的指导意义。
在实际工作中有以下几个方面皆会引起测量误差。
1.不同的测试方法引起的误差。
如定压法与定流法的误差,容积法和加载法的误差。
扬声器(喇叭)参数说明一、功率功率这个参数,其实是衡量一个音箱性能的基本参数,只是由于厂商的的有意回避,所以在很多产品的说明上,功率变成了一个没有什么意义的参数。
音箱标注的功率主要有以下几个:1、额定输出功率(RMS):RMS功率可以说是所有功率标注方法中唯一真正有意义的,它指的是功放电路在额定失真范围内,能够持续输出的最大功率。
也称为"有效功率"。
我们在前面探讨功放电路时所指的功率一般都指的是额定输出功率。
2、音乐输出功率(MPO):指的是在失真不超过规定范围的情况下,功放电路的瞬间最大输出功率。
3、峰值音乐输出功率(PMPO):指的是完全不考虑失真的情况下,功放的瞬间最大输出功率。
后两种功率其实是没有意义的,因为它们所谓的"瞬间"往往是根本听不出来的几个毫秒。
但是,很多厂商处于希望把自己的产品功率标大的心理,往往乐于使用这两种标注,特别是PMPO功率。
市场上多见的诸如数百瓦的音箱大都是如此,甚至有些音箱把自己的功率标为2000瓦!这真是笑话!真正2000瓦的功放及音箱足以令你居住的小区里每一个人都听到你家里的音乐声,就是真正300瓦的音箱也足以吵的整栋大厦不得安宁,难道是一个小小的桌面音箱能够做到的?难怪PMPO功率被发烧友戏称为"JS功率"。
按照一般的实践,PMPO功率与RMS功率之间的比值一般为5-8:1,也就是说,标称自己300W的音箱,其实不过是个输出功率为30W左右的普通音箱而已!真正的名牌大厂是不会使用PMPO功率的,如果产品真的出色,何必要用这种遮人耳目的方法?所以说,看到PMPO的标识,至少表明厂商都对自己的这个产品信心不足。
除了功放部分以外,多媒体音箱中的功率参数还包括扬声器最大承受功率和电源最大输出功率。
这三个参数中最小的一个就是音箱的最大输出功率。
而且这三个参数之间也存在一定的搭配关系,例如RMS功率必须小于扬声器最大承受功率,否则就会烧坏扬声器。
音箱技术参数详解音箱技术指标解析时下许多音响指标良好,却不忍卒听;而有些听音尚可,却经不起客观的物理测试。
音响指标日益飙升;音乐感情表达能力除除下降。
这些是事实,特别是国内的产品。
LP的指标几乎不及格,可是还有好多发烧友去追求。
我也来说说楼主所说的7个问题,当然也只能代表我个人的观点!大家有什么不同的看法也希望大家说出来一起分享!1.频响范围从声学的角度来说,声音是以波的形式存在并且传播的,而波是振荡的,因此波的单位是Hz(每秒钟振荡的次数)。
声波的Hz数值越小,声音就越响;Hz值越大,声音就越小。
从人耳的结构而言,理论上最轻听到20000Hz的声音(但在现实生活中几乎很少存在),而一些动物则可以听到更高Hz数的声音,如狗据称可以听到50000Hz。
音箱的频响范围是指该音箱在音频信号重放时,在额定功率状态下并在指定的幅度变化范围内音箱所能重放音频信号的频响宽度。
通俗的说,就是音箱所能发出的最低音和最高音之间的范围。
一般来说放大器在规定的功率状况下,在频率的高、低端增益分别下降-3dB,两点之间的频带宽度称为该放大器的频响范围。
没有仪器我们也能测试,用人的耳朵去测量不仅仅测量了器材也测量了您的耳朵,先告诉大家不同的器材上去测量您听到肯定不一样,器材直接是有误差的。
好的机器误差不大,国产不知名的东西就难说了,如:《雨果发烧碟1》有25Hz-20kHz测试信号。
器材能发出的频响是不一样的,人的耳朵接受能力也不一样,有时候自己没有听到不是它没有发出声音,是您听不到那断频率,我想很多发烧友都测试过自己的耳朵。
人能听到的音频信号大约20Hz~20kHz之间的不同频率、不同波形、不同幅度的变化信号,而事实上那是人一出生时耳朵能听得到的频率范围,20岁以后就越来越窄了,大约在35Hz~18kHz。
您的耳朵能到到在哪一段还是去测量一下吧!2.灵敏度灵敏度是衡量音箱效率的一个指标,它与音箱的音质音色无关的。
普通音箱的灵敏度一般在85—90d B(分贝)之间,有的则可以达到100dB以上。
