Chinese-English Translation:

动圈耳机按开放程度分为开放式、半开放式、封闭式耳机。绝大多数耳机耳塞都属于动圈式耳机,原理类似于普通扬声器,处于永磁场中的线圈与振膜相连,线圈在信号电流驱动下带动振膜发声。

According to the degree of opening, dynamic headphones can be divided into open type, semi open type and closed type. Most earphones are moving coil earphones. The principle is similar to ordinary loudspeakers. The coil in the permanent magnetic field is connected with the diaphragm, and the coil drives the diaphragm to produce sound under the driving of signal current.

分类

classification

①开放式的耳机一般听感自然,佩带舒适,常见于家用欣赏的 hifi 耳机,声音可以泄露、反之同样也可以听到外界的声音,耳机对耳朵的压迫较小。

① Generally speaking, open type earphones have a natural sense of hearing and are comfortable to wear. The hifi earphones, which are commonly used at home, can leak the sound, and vice versa, it can also hear the external voice, and the earphone has less pressure on the ear.

②半开放式:没有严格的规定,声音可以只进不出亦可以只出不进,根据需要而做出相应的调整。

② Semi open: there are no strict regulations, and the sound can only be in and out, and the corresponding adjustment can be made according to the needs.

③封闭式:耳罩对耳朵压迫较大以防止声音出入,声音正确定位,专业监听领域中多见此类。

③ Closed type: the ear muff has great pressure on the ear to prevent the sound from coming in and out, and the sound is correctly positioned. It is common in the field of professional monitoring.

阻抗(impedance):注意与电阻含义的区别,在直流电(dc)的世界中,物体对电流阻碍的作用叫做电阻,但是在交流电(ac)的领域中

Impedance: pay attention to the difference between the meaning of resistance and resistance. In the world of direct current (DC), the effect of an object on current resistance is called resistance, but in the field of alternating current (AC)

则除了电阻会阻碍电流以外,电容及电感也会阻碍电流的流动,这种作用就称之为电抗,而我们日常所说的阻抗是电阻与电抗在向量上的和。

In addition to the reactance and the resistance of the current, the resistance is also called the resistance.

灵敏度(sensitivity):指向耳机输入 1 毫瓦的功率时耳机所能发出的声压级(声压的单位是分贝,声压越大音量越大),所以一般灵敏度越高、阻抗越小,耳机越容易出声、越容易驱动。

Sensitivity: refers to the sound pressure level (the unit of sound pressure is decibels, the higher the sound pressure, the greater the volume). Therefore, the higher the sensitivity and the smaller the impedance, the easier the earphone will sound and drive.

频率响应(frequency response):频率所对应的灵敏度数值就是频率响应,绘制成图象就是频率响应曲线,人类听觉所能达到的范围大约在 20hz-20000hz,成熟的耳机工艺都已达到了这种要求。

Frequency response: the sensitivity value corresponding to the frequency is the frequency response, and the image drawn is the frequency response curve. The range of human hearing is about 20hz-20000hz. The mature earphone technology has met this requirement.
