汉英对照:
Chinese-English Translation:

线控耳机指能在耳机线上控制接入设备的耳机。比如控制远端 MP3 设备的开关机功能、播放和停止功能、音量大小调节功能等,拥有在耳机线上控制远端设备的这些功能都属于线控耳机。

Remote headset refers to a headset that can control the access device on the headphone cable. For example, controlling remote MP3 device’s switch on / off function, play and stop function, volume adjustment function and so on. These functions of remote device control on the headphone line belong to remote control earphone.

由于受到耳机发出信息指令和接收信息指令的设备对信息识别语言版本不同,有些线控所发出的指令信息不能被远端接收设备所识别,而导致线控耳机对这些远端接收设备不起作用。

Due to the different language versions of the information recognition language of the equipment receiving the message command and the message command sent by the headset, some command information sent by the remote control device can not be recognized by the remote receiving device, which results in the remote receiving device not working with the remote control headset.

线控耳机原理

Principle of earphone controlled by wire

线控耳机不管接口类型如何(音频接口、USB 接口等),基本上都是采用四线连接,其中“共用回线 GND”是耳机左右声道、话筒、输出控制的共用回线,这个原理是一定的,只不过厂商为了垄断利益,在线极功用上做些手脚。例如插头由上到下有四个电极,如果把第一和第三电极接线对调,其现象是一个耳机无声且线控失效、话筒失效;如果把第三和第四电极接线对调,其现象是两个耳机都无声。改动时,只需在微动开关处,按照原理图捋顺接线即可。

Regardless of the interface type (audio interface, USB interface, etc.), wired earphones are basically connected by four wires. The “common return line GND” is the common return line of the left and right channels, microphone and output control of the headset. This principle is certain, but the manufacturers do something about the online polar function in order to monopolize the benefits. For example, the plug has four electrodes from top to bottom. If the wiring of the first and third electrodes is switched, the phenomenon is that one headset is silent and the wire control is invalid, and the microphone is invalid; if the wiring of the third and fourth electrodes is switched, the phenomenon is that both earphones are silent. When changing, it is only necessary to smooth the wiring at the microswitch according to the schematic diagram.

根据原理图不难得出判断线控耳机插头各电极功用的方法:用欧姆表测量,其中一个电极分别与另外三个电极间不导通,则该电极是控制极;剩下的三个电极中,若两个电极间呈现了最大阻值,那么这两个电极分别是耳机的左右声道线,剩下的电极就是共用回线。这里所说的最大值是相对于剩下的三个电极中,任意两电极间的阻值而言,左右声道耳机的线圈阻值会相差 0.1~0.2Ω .

According to the schematic diagram, it is not difficult to determine the function of each electrode of the earphone plug by wire: if one electrode is not connected with the other three electrodes by ohmmeter, then the electrode is the control pole; if the maximum resistance is present between the two electrodes, then these two electrodes are the left and right channel wires of the earphone, and the remaining electrodes are the common return line. The maximum value mentioned here is relative to the resistance between any two electrodes among the remaining three electrodes, and the coil resistance of left and right channel headphones will differ by 0.1-0.2 Ω
