1.2.HEY. HAVE WE SEEN YOU HERE BEFORE?Register your speaker at .Information about where you bought it and how you’re using it is like gold for the people who make these speakers. Do them a solid, will ya?Por manual de instrucciones e información de garantía en español visítenos en There are lots of cool Jam speakers.Check them all out at PACKAGE CONTENTSSpeakerUser Manual AdaptorCordProtective Cap Language Selector PinJUST CHARGE ITCharging the speaker is so easy you’ve probably figured it out by now, but just i n case, use the wall outlet.1. The cord that came with the speaker— j ust plug it into theadaptor.Plug it in and your speaker will be ready for an epic night in no time. You should go get ready too! It needs about 5 hours for 12 hours of party time.CONTROL YOUR DESTINY…OR AT LEAST YOUR SPEAKER1. This is the power button, press and hold for 5seconds to power on2. It speaks too.

Protective cap FEATURES:ALLOW US TO SHED SOME LIGHTBLUETOOTH® CONNECTION: IT’S A SETUPLike any amazing couple, this one starts with a connection—one between your device and the speaker’s Bluetooth.1. We know you’re probably going to think, “derp” with thisone, but we have to say it: Make sure the smartphone, tablet or computer you want to hook up to the speaker has Bluetooth. (There. We got that out of the way.)2. Turn on the speaker and look for the little blinking light.3. Do whatever your device needs you to do on its end.(We don’t know what you’re using. We’re not spies.)4. Look for Jam Storm in your device’s Bluetooth list orclick YES—whatever pops up on your device—and BAM!you’re connected.5. Now hit PLAY on your speaker and crank it up—or downif you’re lame.You’re probably only going to have to do this once, unless your device goes through a major I-just-dropped-it-in-the-pool kind of reboot. The device and Bluetooth will find each other every time just as long as the speaker is set to Bluetooth and your device’s Bluetooth is, you know—on.If you’re connecting to a computer, you may have some extra steps on that end. You’ll have to get that information from the computer company.Depending on your device you may be prompted to enter a pairing code. If prompted enter “0000” as the code.Press and hold the PLAY/PAUSE button for 5 seconds to activate pairing mode.Note: If you turn on your Storm but haven’t started the party, it will automatically power off after 2 minutes of unpaired inactivity. BRING THE STORM, BRING THE THUNDERHave a playlist that needs a little—scratch that—a lot of extra bass? Hit the Storm button for a sound so deep you feel the boom in your body.Note: To keep Storm base tacky anddirt-free, gently wipe with a damp towel.When not in use, place the includedprotective cap back on the Storm base.HELLO? SPEAKERPHONE? YES!When friends call asking to join the party—and you know they will—answer the phone without disconnecting from your JAM Storm. Yes, that’s right. Your speaker is a speakerphone too. How amazing is that?1. Make sure your phone and speaker are connected throughBluetooth.2. Answering and ending a call works the same way: simply clickthe PLAY/PAUSE button on your Storm.3. If you’d rather not talk, hold down the PLAY/PAUSE button onyour Storm for three seconds to ignore the call.THE COOLEST PART: The Storm knows when a call is coming in and pauses the music before ringing. When you hang up, the music starts where it left off—and so does the party. If it’s you making the call, just start dialing from your phone, and the Storm automatically does its hands-free thing. Isn’t it refreshing to know your speaker totally gets you?THE VOICE FROM WITHINWhen your Jam Storm isn’t rocking out, it can tell you all sorts of things it’s doing: when it’s powering on, ready to pair, paired, at maximum volume, incoming call, ignoring a call, ending a call, charging and powering off.Just like the global gadget it is, your speaker toggles between several languages or no language at all. Your speaker can parlay with you in English, Spanish, French, or Portugese. But, making the change is as simple as poking the included Language Selector Pin into the small hole on the bottom. Toggle through until the speaker starts speaking your language.COMING CLEANA soft, dry towel is all you need to clean off your speaker. Using water, harsh cleaners or anything else only starts messing with the mechanics inside. So, yeah, don’t do it.STUFF THE GOVERNMENT MAKES US SAYFCC DISCLAIMER:Note: This device complies with part 15 of the FCC Rules.

第一章关于声音1-1．声音是什么？所谓声音就是生理学上说的听觉神经受到刺激后引起的感觉，对于物理学来讲就是引起这种感觉的原因的物理现象。
也就是说大气中传播的纵波（疏密波）。
另外，在空气以外的气体，液体，固体中也有音波在传播，但是这里我们只讲空气中的声音。
接下来，在空气中传播的疏密波进入耳朵，通过外耳道到达鼓膜，因为鼓膜内侧的压力几乎是一定的，就正好像压力型microphone的振动板一样，当疏密波很密的时候鼓膜内侧被压弯曲，当疏的时候鼓膜被外侧牵引弯曲，因此鼓膜是对应压力变化振动的。
这个鼓膜的运动是经过槌子骨等的传达结构传给听觉神经的，因此就可以被作为声音感觉到了。
我们的耳朵能听到各种的声音。
风的声音，雨的声音，波的声音，人的说话声，脚步声，动物的鸣叫声，乐器声，交通机关的噪音，警笛等的无数声音包围着我们。
这里我们就只考虑如下的几种声音的种类。
1）乐声：就是弦乐器的声音，管乐器的声音，歌声的母音，音叉的声音等之类的，在一定的周期上以相同的波形反复的声音并能给人以快感的声音。
2）非乐声：乐音以外的所有的声音，并给人以不快感的即所谓非乐音，但是爽快地的风声，小河的淅淅沥沥的声音等并不会给人带来不快感，韵律乐器的打击声等也可以考虑是乐声，乐声和非乐声的境界未必就能明确的区分开。
3）噪音：听起来无法忍受的声音，这些全部都是主观的分类。
例如，赛车迷虽然很陶醉于sports car的排气声，但是对于其他人来说简直就是令人讨厌的声音。
即使是电吉他的声音，有人认为它是音乐也有人认为那不是音乐，所以这种评价就是截然相反的。
4）纯音：拥有正弦波形的声音，且是单一频率的声音这个在自然界是不存在的，音叉的声音就与这个很接近。
5）复合音：频率不同的复数各纯音合成的声音6）单音：一个基本音和拥有其整数倍频率的倍数音组成的音乐。
7）协和音：是很多单音结合的音,每个基本音的频率都形成比较简单的整数比,之后调和听起来得音色即协和音.例如,do和so的基本音频率比是2:3,do的3倍和so的2倍一致之后再调和出来的.1-2.音的3要素从物理学上讲：高,强,音色被称为音的3要素.1）高度:女生的声音要比男生高,钢琴的键盘从右边开始依次会出现高音.这是根据发音体的单位时间内的振动数的大小,振动数越大声音就听起来越高.人耳朵听音的频率范围大体是20~20,000Hz.人类的声音是80~1,000Hz，音乐上使用的基音的频率是16~4,000Hz 左右，1-3的图上有显示各种乐器的基本音的频率范围。
