They are designed at Bose ® to bring you high-quality listening pleasure.The Direct/Reflecting ® tweeter inside each speaker creates a pattern of sound similar to what you experience at a live concert. In addition, the Stereo Targeting ® tweeters help establish the natural balance of sound, for full enjoyment of stereo even when you move around the room. These distinct left and right speakers also feature tuned port enclosures that contribute to their deep, room-filling bass. An advanced crossover design adds to the realism and clear definition of both musical instruments and voices.Your 301 Series IV speakers are significantly different from conventional speakers, so be sure to read this owner’s guide. It will help you set up and use your speakers properly, for the greatest enjoyment.Unpack the cartonCarefully unpack the carton and save all packing materials for possible future use. Check the carton contents (Figure 1).If either speaker appears damaged, do not use them. Instead, repack both speakers in the original carton and notify your authorized Bose dealer immediately.Note: Now is a good time to record the speaker serial numbers on page 2 of this guide and on your warranty card.CAUTION:T o avoid danger of suffocation,keep the plastic bags that wrap these speakers out of the reach of children.Select the locations for your 301® speakersBose® 301 speakers are designed to fit horizontally on a table or shelf (Figure 2). Be sure to choose a stable and level surface for each speaker.Place the left and right speakers (marked on the back of each one) on the left and right sides of your room, as you face them. Exactly where you put them depends on the size and style of your room and where you think they sound best. Feel free to experiment to find a location that is both convenient and provides the sound you prefer.Note: Because the grilles on the front of each speaker protect the drivers inside, we recommend that you do not remove the grilles.Here are some basic guidelines:•Place the speakers 4 to 12 feet (1 to 4 m) apart.•Choose a stable and level surface for each speaker, and attach the rubber feet.•Leave at least 12 inches (30 cm) of space from the end of a speaker to the side wall.•Leave at least 18 inches (45 cm) from the speakers to the floor or ceiling.•Leave at least 24 inches (60 cm) from the speakers to any TV screens or monitors.•Keep the back of the speakers within 18 inches (45 cm) of the wall behind them.•Do not place the speakers exactly halfway between the floor and ceiling or any other sound-reflecting hard surface.•Do not put the speakers in a vertical position.Note: Bose speaker stands or wall brackets can extend your placement options. See “Optional accessories” on page 10.CAUTION:301 speakers are designed specifically for placement on a stationary shelf, table, or stand. On smooth surfaces like marble, glass or highly pol-ished wood, vibrations may cause the speakers to slide. So be sure to attach the self-adhesive rubber feet to the bottom surface of each speaker for added stability and protection. The feet go in the corners of the flat surface, inside the seam.Do not use these speakers in a moving vehicle.T o mount the speakers on a wall, use only the Bose WB-3 wall mounting bracket. Please follow the mounting instructions that come with these brackets. Improperly mounted speakers may fall, causing injury and damage.cover of this owner’s guide.Figure 2Placement guidelinesCAUTION:For the most realistic soundimage, make sure the leftspeaker is placed on the leftand the right speaker is onthe right side of your room, asyou face them.AM181869_04_V.pdf October 30, 2001 5CAUTION:Never use broken or frayed wiring, which can result in electrical shock or damage.Choose the cordIt is important to use the proper gauge (thickness) of speaker cord. Standard zip cord (2-conductor, 18-gauge wire) works for most applications. Y ou can find this wire at most electrical and hardware stores.You will need thicker wire if your speakers will be more than 30 feet (9 m) from a receiver (or amplifier). Refer to the wire recommendations under “T echnical information” on page 10, or contact your authorized Bose ® dealer for more information.Note: Before running speaker cord through a wall or under a floor, check your localbuilding code requirements and safety regulations. You may want to contact an electrical installer for this information.Prepare the cordSpeaker cord consists of two insulated wires. The insulation around one wire is marked(striped, collared, or ribbed). This marked wire is always positive (+). The plain wire is always negative (–). These wires correspond to the red (+) and black (–) terminals on the speakers and the receiver.At the ends of each cord, strip approximately 1⁄2 inch (12 mm) of insulation from both wires.Twist the bare end of each wire so loose strands will not touch across terminals. Be sure to connect each wire to the proper terminal (positive to positive and negative to negative).Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully.Make the connectionsJust press the terminal tab on the back of each speaker to insert the appropriate wire CAUTION:Before making any connec-Check the connectionsCheck to be sure all connections are made positive to positive (+ to +) and negative to negative (– to –) (Figure 4). Make sure that no loose strands of wire touch across terminals. Bridged wires can short circuit and damage the amplifier. Tighten any loose connections before you plug in the receiver and turn it on.T est the speakersTo make sure your speakers operate correctly:1.Place the speakers less than 6 inches (15 cm) apart, facing each other.2.Turn on your receiver. Set the receiver to MONO (monophonic), if that is an option onyour receiver.3.Make sure that all special effects (such as surround sound) are turned off.4.Set the balance control to normal (center position).5.Play some deep bass passages of music through the speaker.The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, one of the connections may be reversed, causing the speakers to play out of phase (refer to “Make the connections” on page 6).To correct the problem, make sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –). Then repeat steps 1 through 5 above to re-testthe speakers.Figure 4 Completed connectionsAM181869_04_V.pdf October 30, 2001 7Enjoying sound in a variety of waysBose® 301® Series IV Direct/Reflecting® speakers are designed to work with a variety ofstereo receivers and amplifiers. The open, spacious performance of these speakersalso makes them an ideal choice for home theater, or for listening to CD’s, tapes, or radiobroadcasts (Figure 5).301® Series IV Direct/Reflecting®speaker sound pathCleaning the speakersClean the surface of your speakers with a soft damp cloth. Do not use any sprays near thesystem or allow liquids to spill into any openings. Also, do not use any solvents, chemicals,or cleaning solutions containing alcohol, ammonia, or abrasives.The speaker grille panels require no special care. You may vacuum them carefully to removedust.Warranty periodBose 301 Series IV Direct/Reflecting® speakers are covered by a limited 5-year transferablewarranty.

《基于麦克风阵列的语音增强研究》篇一一、引言随着智能设备的广泛应用，语音交互技术在人机交互中占据了越来越重要的地位。

其中，麦克风阵列技术的应用，使得语音识别系统的性能得到了显著提升。

基于麦克风阵列的语音增强技术，可以有效地提高语音信号的信噪比，从而改善语音识别的准确率。

本文将针对基于麦克风阵列的语音增强技术进行深入研究，并探讨其在实际应用中的效果。

二、麦克风阵列技术概述麦克风阵列是指将多个麦克风按照一定的几何结构排列在一起，通过信号处理技术对多个麦克风的信号进行融合，以实现空间滤波、语音定位和语音增强等功能的技术。

其基本原理是利用不同位置麦克风的信号差异，通过算法处理，实现噪声抑制、回声消除等效果。

三、基于麦克风阵列的语音增强方法（一）波束形成波束形成是麦克风阵列中常用的一种语音增强方法。

其基本思想是通过加权求和的方式，将指向目标方向的信号加强，同时抑制来自其他方向的干扰噪声。

波束形成的算法包括相位变换法、最小方差法等。

（二）盲源分离盲源分离是一种利用多个麦克风的信号对音频信号进行源分离的技术。

其基本思想是将不同位置的麦克风信号进行时间-空间变换，通过多通道线性系统来分离出各个音频源的信号。

盲源分离方法可以有效地去除非目标方向的干扰噪声，提高语音识别的准确率。

（三）噪声抑制噪声抑制是麦克风阵列中常用的另一种语音增强方法。

其基本思想是通过估计和消除噪声信号来提高语音信号的信噪比。

常用的噪声抑制方法包括基于频谱减法、基于子空间方法的噪声抑制等。

四、实际应用效果分析在实际应用中，基于麦克风阵列的语音增强技术能够有效地提高语音信号的信噪比和识别率。

通过使用波束形成算法，能够明显抑制非目标方向的噪声和干扰信号，提高目标方向上的语音清晰度。

同时，通过盲源分离和噪声抑制等算法的应用，可以进一步提高语音识别的准确率。

此外，基于麦克风阵列的语音增强技术还可以应用于多语种、多环境下的语音识别系统中，以适应不同的应用场景和需求。
