目前,录音机的使用已日趋普遍,使用范围亦越来越广泛。录音机的种类很多,总起来说可分为开盘式与盒式二大类。开盘式中又有电子管式与晶体管式之分。录音机的结构比较复杂,它具有下列几个特点: 1.它除了电一声转换之外,还有电-磁转换,这个电-磁转换是非线性的。 2.它的录音与放音之间有一个转换过程,这个过程会带来一定损失。 3.要精确地完成上述两个转换,必须借助一套复杂而精密的机械传动机构紧密配合,在这个机-电转换过程中必然会给录放音质量带来一定损失。由于存在这三个转换过程,在每个环节上如果稍有偏差,便会使录放音质量受到影响。因此,录音机的“发病率”一般要比收音机、电视机高得多。更值得注
At present, the use of tape recorders has become increasingly common, the use of more and more widely. There are many types of recorders, in general, can be divided into two types of opening and cassette. Opened in the style of electronic tube and transistor points. The structure of the recorder is more complex, it has the following characteristics: 1. It in addition to the electrical conversion, there are electro-magnetic conversion, the electro-magnetic conversion is nonlinear. 2. It has a conversion process between recording and playback, this process will bring some loss. 3. To accurately complete the above two conversions, we must rely on a complex and sophisticated mechanical transmission mechanism to work closely with the machine - in the conversion process will inevitably bring some loss of quality recorded audio. Due to the existence of these three conversion processes, if there is a slight deviation in each link, the recording and playback sound quality will be affected. Therefore, the recorder “morbidity” is generally much higher than radios, televisions. More noteworthy
