What does the letter L and R on the earphone mean?

We all know that the earphones are usually marked with the letters "L" and "R". What do these two letters mean? I believe many people know that this is an important sign to distinguish between the left and right ears, but it is not only that. Today, Xiaobian will take you to understand the familiar and unfamiliar "L" and "R".

Headphones and earphones generally have left and right channels. First of all, the full name of L in English is: left, Chinese means: left, also represents the left channel, that is, worn on the left ear. The full name of R in English on the earphone is: right, Chinese means: right, and it also represents the right channel, that is, worn on the right ear.

As for what is the channel?

In the stereo (the stereoscopic sound) of the sound output of the electronic device, the left and right channels can respectively play the same or different sounds, and the stereo sound change effect from left to right or right to left is generated, which is simple. The left and right channels are the sound outputs produced by the hearing range of the human left and right ears in the electronic device.

Why is it left and right? what's the effect?

The general stereo headphones will be divided into left and right channels. The reasons and functions of this are as follows:

First, it is related to the sense of direction of the sound.

Stereo, the left channel is the accompaniment, the right channel is the vocal, in the movie or the game, the sound can be used to judge the direction of the sound.

Second, it is related to human structure.

The average person's left ear should be sensitive to the right ear. In order to fit the human body structure, it is necessary to divide the earphone into left and right.

All of the above prove that the sounds from the two channels are different. Of course, for most ordinary listeners, there is not much difference. I feel that the sounds are similar or the same, but in fact, if you listen carefully, there is still a difference. And when you wear it, you can feel it. If you wear it, you may feel uncomfortable or unable to wear it. Therefore, it should be properly worn, used and stored according to the instructions in the earphone manual.
