Problems solved by technology

However, if it is fixed by welding, the encoder is easily misaligned and cannot be docked with the knob, and because of the interference of the docking position deviation, the knob is difficult to rotate and the adjustment sensitivity is very poor.

Abstract

A volume adjustment mechanism comprises a rotary knob, an encoder, a sleeve and an elastic member. The rotary knob comprises a rotating shaft and a transmission bar arranged on one end of the rotatingshaft. The elastic member is of a three-dimensional framework structure. The encoder is received in the elastic member and the elastic member is fixed on the rotating shaft in order to suspend the encoder. A rotating hole is formed in the shaft core of the encoder and the transmission bar is received in the rotating shaft hole and is in stop rotation connection with a shaft core. The sleeve comprises a correcting part and two extension parts arranged on one end of the correcting part. The two extension parts are oppositely arranged. The rotating shaft can be rotatably positioned inside the correcting part. The encoder and the elastic member are limited between two extension parts. The rotary knob drives the shaft core to rotate relative to the encoder in order to change an output signal of the encoder. The volume adjustment mechanism utilizes the sleeve and the elastic member to fixedly suspend the encoder right under the rotary knob, which is easy for the encoder to perform rotary correction docking with the rotary knob.

Description

technical field [0001] The invention relates to a volume adjustment mechanism and an electronic device equipped with the volume adjustment mechanism. Background technique [0002] Existing electronic devices, such as handheld players, audio-visual equipment, etc., use adjustment mechanisms to adjust volume or audio. The volume adjustment mechanism generally includes a knob and an encoder, and the encoder is usually fixed on the integrated circuit board of the electronic device by conventional welding. However, if it is fixed by welding, the encoder is easily misaligned, so that it cannot be docked and assembled with the knob, and because of the interference of the docking position deviation, it is difficult to turn the knob, and the adjustment sensitivity is very poor. Contents of the invention [0003] In view of this, it is necessary to provide a volume adjustment mechanism capable of improving adjustment sensitivity and facilitating alignment and docking, and an electr...
