Law volume regulator

Abstract

The present invention discloses a law volume regulator, a PCB, an encoder and a pulsator. The upper part of a corn on one side of that PCB board is provided with an FPC soft connected board, the encoder is welded to the side of the FPC soft joint plate, the upper part of the encoder is provided with a bracket, the lower end of the bracket is installed on the side of the FPC flexible connector board, the middle part of the encoder is provided with concave-convex blocks, the side parts of the concave-convex blocks are connected with elastic plates, a cavity is formed between the elastic plates,the pulsator is composed of a connecting block and a handle head, the end part of the connecting block is connected with the handle head, and the connecting block is inserted into the cavity on the side away from the handle head. A handle head of that invention is rotated under the action of an external force, the power is transmitted to the encoder, and the corresponding signal output and the rated frequency return are generated. The signal output is transmitted to the PCB board by the FPC soft connector board, and the rated frequency return is transmitted to the handle head and the FPC softconnector board, and digestion is generated on the FPC soft connector board, so that the power return of the rated frequency is not bound.

Description

technical field [0001] The invention belongs to the technical field of music playing, and in particular relates to a law volume adjuster. Background technique [0002] At present, the overall product in the market is composed of a pulsator, an encoder, and a PCB. The common way is that the encoder is welded on the PCB, and the pulsator is inserted into the central hole of the encoder, and the volume is adjusted by turning the pulsator. [0003] However, the above-mentioned production and adjustment have the following problems: 1: The encoder’s own rated frequency force return is bound, and the blind operation experience is very poor; 2: It is easy to desolder, resulting in functional failure; 3: High production loss, Waste of resources; 4: The feel and tightness of mass production cannot be consistent. Contents of the invention [0004] The purpose of the present invention is to provide a law volume regulator, which can be realized simply and conveniently so that the sens...
