The difference between speaker and receiver/喇叭与受话器的区别

Amount of reading：，Release time：2014-03-04 16:08:13

Speaker and the receiver， the basic structure is similar, it is through the voice coil and magnet force, driven diaphragm sound.

There are several major differences as follows:

The use of the horn is usually different: there are dozens of centimeters or even tens of meters away from the user's headset, as horn of the size of the set, and the receiver is tight

Affixed to the ear to use, the diaphragm;

Voice coil and other materials are different: the speaker needs to bear a larger power, so the film thickness is thicker, starting from the thin 18u, the larger the size, the greater the power, the diaphragm will be

The more thick, a small power, but low frequency curve is better, so the 6u-12u diaphragm is generally used, in addition to the diaphragm, the receiver will usually add up

Paper or cloth tuning, adjusting the frequency response, to meet various specifications or with resonant cavity mechanism;

Electrical characteristics of the different: the most common speaker for 4-8ohm, too high impedance will make the speaker need a higher voltage to drive, 0.2W to dozens of W have, by

The words from 16,32,64ohm to 150ohm have a look at the customer's line design, the general power of only 0.01W to 0.1W.

喇叭与受话器的基本构造是大同小异的，都是透过音圈与磁铁的作用力，带动振动膜来发声。

有如下几点较大差异：

使用上的不同：喇叭通常是离使用者的耳机有几十公分甚至几十公尺的距离，视喇叭的大小不同而定, 而受话器是紧

贴着耳朵来使用的，膜片；

音圈等材质不同：喇叭需承受较大的功率，故膜片厚度都较厚，从最薄的18u开始，尺寸愈大，功率愈大，膜片就会

愈厚重，受话器的功率小，但要求低频曲线要好，故一般采用6u-12u的膜片，除了膜片之外，受话器通常会加贴调音

纸或调音布,来调整频率响应，以符合各种的规范或是来配合机构的共呜腔；

电气特性上的不同：喇叭最常见的为4-8ohm，太高的阻抗会使喇叭需要更高的电压才能驱动，0.2W到几十W都有，受

话器从16,32,64ohm到150ohm都有，看客户的线路设计匹配，一般的功率只有0.01W到0.1W。
