Elastic sheet assembly of elastic sheet type contact mobile phone loudspeaker and processing method thereof

Abstract

The invention relates to the field of earphone accessories and machining and particularly relates an elastic sheet assembly of an elastic sheet type contact mobile phone loudspeaker and a processing method thereof. The assembly comprises an S-shaped supporting elastic piece comprising an upper section surface, a middle section surface and a lower section surface, all of which are orderly arrangedat intervals. Two ends of the middle section surface are sequentially bent upwards and downwards to be connected to the corresponding ends of the upper section surface and the lower section surface, and the upper section surface, the middle section surface and the lower section surface are integrally bent. The middle of the middle section surface is punched and bent to form an upper auxiliary supporting section and a lower auxiliary supporting section. The upper auxiliary supporting section is used for abutting against and supporting the upper section surface and the middle section surface, and the lower auxiliary supporting section is used for abutting against and supporting the middle section surface and the lower section surface. When in use, the elastic sheet can play a good supportingrole and has a good resetting effect. In addition, elastic sheet blank is convenient to obtain, required parts can be directly produced after the blank is subjected to blanking and other procedures,and waste in the machining process is small.

Description

Technical field [0001] The invention relates to the field of earphone accessories and machining, in particular to a shrapnel type contact mobile phone speaker shrapnel assembly and a processing method thereof. Background technique [0002] The loudspeaker is a kind of transducer device that transforms the electric signal into the acoustic signal. The performance of the loudspeaker has a great influence on the sound quality. The speaker is one of the weakest components in audio equipment, and it is the most important component for audio effects. There are many types of speakers, and they are widely used in earphones. The shrapnel-type contact mobile phone speakers on the market are among the more common types of micro speakers, which mainly include vibration modules (diaphragm, voice coil, dust cover, etc.), magnetic Circuit module (including magnetic upper plate, magnetic column, magnetic lower plate, magnet, etc.) and components such as frame, blank holder, shrapnel, terminal f...

AI Technical Summary

Problems solved by technology

However, due to certain defects in the structural design of the existing shrapnel, it is easy to break during long-term use, and its structure is mostly irregular, so that it needs to select the workpiece blank to be used in the process of processing and manufacturing. The removal of waste is more serious, and the waste of processing materials is more serious
