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 small series introduces the application of potentiometer in earphone in detail. The specific contents are as follows: application 1. Mobile phone hands-free
The main requirements for potentiometer are: the resistance meets the requirements. The contact between the central sliding end and the resistance body is good and the rotation is smooth. For potentiometer with switch, the switch part shall act accurately, reliably and flexibly. Therefore, the performance of the potentiometer must be checked before use. 1. Resistance measurement: first, according to the resistance value of the potentiometer to be measured
