Potentiometers are widely used in headphones. About 10 potentiometers can be used on the headset, and these potentiometers can be divided into many kinds according to different materials and appearance colors. The following is a brief introduction to the application of potentiometers in headphones. The specific contents are as follows:

Application 1: handsfree.

Earphones such as mobile phone earphones are used to listen to music and listen to earphones. The earphones are required to be small in size and high in sound quality. This kind of earphone requires the potentiometer to have small volume, good service life, good sound quality and so on. Generally, the model of youxingda electronics factory is; R080g-10 / 1-b500 Ω potentiometer and r09n-12 / 1.9-b1k potentiometer In particular, there are many rotary potentiometers with r080g - 10 / 1-b500 Ω for LG Chocolate mobile phone headphones and Dopod mobile phone headphones, r09n-12 / 1.9-b1k for others, and c0510q-b500 Ω for some Nokia headphones recently Their common feature is small and demanding This is also one of the most advantageous potentiometers made by youxingda electronics factory.

Application 2. Computer headset.

Generally speaking, potentiometers for computer earphones, especially for Internet cafes, are the most common. Almost every earphone uses a potentiometer. Generally, the model of UFIDA Xingda electronics factory is r1001gs - 14 / 1-b1k potentiometer. Text description: diameter 14mm, thickness 1mm, double closed, B1K dial potentiometer. Some Chaoyang earphone manufacturers also use r1001gs-14 / 1-b500 Ω potentiometers. The difference between them is the resistance value. Because the impedance of the B500 Ω potentiometer is small, it feels relatively large when the sound is adjusted to the maximum, but the feeling of stereo is not as good as 1K. This is based on the needs of the market. Black or white knobs or even knobs of other colors can be equipped according to different headphone tuning shells.

Application III. MP3 music headphones and other music headphones.

This kind of earphone, represented by Sennheiser earphone, has fashionable appearance, small tuning shell and high requirements for sound quality. This kind of earphone generally adopts the direct sliding potentiometer with the model of c0510q-b500 Ω or B1K of youxingda electronics factory. The sliding distance of this potentiometer is 5mm. The appearance size is small, so many are used. The push handle is generally black or white according to the earphone tuning shell. According to different requirements, this direct sliding potentiometer can be divided into true duplex and false duplex.

Application 4. Portable headphones for repeater, CD player, radio, game console, etc.

These earphones are generally sold as accessories, and the sound quality requirements are not particularly high. Generally, the potentiometer of youxingda electronics factory is r1001gs - 14 / 1-b500 Ω. Some Radio Headphones even use a potentiometer with a model of r127ns-b500 Ω. The sound quality of this potentiometer is not very good, only mono, but when it is turned to the minimum sound, it can not only cut off the sound, but also turn off the power supply. Therefore, some factories are using it, but there are many earphones used in gear.
