Abstract

A silent potentiometer of the present invention is composed of a muffler, a potentiometer housing, a rotating shaft fixing plate, a rotating shaft, a sliding shaft, a gear switch and a sound insulation board. The potentiometer housing is provided with a muffler. One side of the device is provided with a rotating shaft fixing plate, and the muffler is fixedly connected with the rotating shaft fixing plate, and a rotating shaft is arranged around the rotating shaft fixing plate, and the described rotating shaft fixing plate is fixedly connected with the sound insulation board, and the sound insulation board is connected with the sound insulation board. The sliding shaft is hinged, and the sliding shaft is connected with the gear switch. The beneficial effect of the above technical solution is that the noise of the potentiometer during operation can be reduced.

Description

technical field [0001] The invention relates to electronic products, in particular to a mute potentiometer. Background technique [0002] A potentiometer is a resistive element with three leads and whose resistance value can be adjusted according to a certain change rule. It is usually composed of a resistive body and a rotating or sliding system, that is, a moving contact moves on the resistive body to obtain a partial voltage output. . But the potentiometer will produce sliding noise when it is working. Contents of the invention [0003] The purpose of the present invention is to provide a silent potentiometer to solve the problem of high noise in the prior art. [0004] The technical solution of the present invention is: a mute potentiometer, which is composed of a silencer, a potentiometer casing, a rotating shaft fixing plate, a rotating shaft, a sliding shaft, a gear switch and a sound insulation board, and the potentiometer casing is provided with a silencer , on...
