目前使用的动圈式(即电动式)扬声器阻抗有好多种,例如3.5欧,4欧,8欧,16欧,25欧,50欧等,为什么有这么多种呢?它的原因很多,但总起来说不外下列几种原因:1.适应电路上的需要;2.工艺上的考虑。一、电路上的要求由于电路不同及所用放大器件不同就要求不同的最佳负载。例如电子管放大器一般要求几百欧至几千欧的负载。所以最早生产的扬声器例如舌簧扬声器就是800欧或1000欧的。但是由于舌簧扬声器的频率响应不好,而且
There are many reasons why there are many reasons why there are so many kinds of impedances that are currently used in dynamic (ie electric) loudspeakers, such as 3.5, 4, 8, 16, 25, 50 ohm Generally speaking, but the following reasons: 1. To adapt to the needs of the circuit; 2. Process considerations. First, the circuit requirements Due to the different circuits and amplifiers used to require different from the best load. For example, tube amplifiers typically require loads of several hundred to several thousands of ohms. So earliest production of speakers such as reed speakers is 800 or 1000 Europe. However, due to the poor frequency response of the reed speakers, moreover
