The potentiometer is widely used in earphones. There are about 10 kinds of potentiometers that can be used on the headset, and they can be divided into many kinds depending on the material and the appearance and color.

Application 1. Hands-free mobile phone.

Earphones such as mobile phone earphones are used to listen to music and receive earphones, which require small size and high sound quality. This kind of earphone requires the potentiometer to be small in size, good in life, good in sound quality and so on. Generally, the model of youxingda electronic factory is adopted. R080G - 10/1 - B500 Ω potentiometer and R09N - 12/1.9 - B1K both. Especially the LG chocolate phone dopod mobile phones and headsets with R080G - 10/1 - B500 Ω the rotation of the potentiometer, and the other with R09N - 12/1.9 - B1K, more recently, there is also a part of nokia headset use C0510Q - B500 Ω. Their common characteristic is small, high requirements. This is also the dongguan auspicious electronic co., LTD. Is one of the most advantage of the potentiometer.

Application 2. Computer headset.
