Wire bending method of free lead wire of voice coil

Abstract

The invention relates to a wire bending method of a free lead wire of a voice coil, comprising the following steps: providing a vibrating diaphragm which is adhered with the voice coil with the free lead wire; providing a press ring which is provided with a positioning part, wherein the positioning part is provided with a first lateral surface, a second lateral surface opposite to the first lateral surface and a connection surface connected with the first lateral surface and the second lateral surface; providing a support device which is provided with a support column supporting the positioning part of the press ring and a pair of grooves containing the free lead wire of the voice coil, wherein the inner diameter of the support column is shorter than the distance between the first lateralsurface and the second lateral surface; placing a vibrating diaphragm device adhered with the voice coil on the support device, enabling the free lead wire of the voice coil to be respectively contained into the pair of grooves of the support device, then covering the press ring on the support device and connecting the press ring with the support device so that the positioning part of the press ring is inserted into the support column of the support device and the first lateral surface of the positioning part supports against the support column; rotating the press ring, and bending the free lead wire of the voice coil. The invention can ensure the one-step molding of the wire bending angle of the free lead wire of the voice coil.

Description

【Technical field】 [0001] The invention relates to a method for bending a free lead wire of a voice coil, in particular to a method for bending a free lead wire of a voice coil used in a sound generator. 【Background technique】 [0002] In the process of rapid development of portable devices such as mobile phones, people have increasingly strong requirements for the functionality of products. For the music appreciation function of mobile phones, in order to make the entertainment effect stronger, the mode of music with vibration appears. Therefore, the development of sound generators has also accelerated accordingly. A sound generator of a related structure includes a vibration system, a magnetic circuit system and an auxiliary system, wherein the vibration system includes a diaphragm and a voice coil connected with the diaphragm, and the auxiliary system includes a basin frame. The voice coil is generally formed by winding metal wires, which includes a ring-shaped part and a...

AI Technical Summary

Problems solved by technology

[0004] However, in the wire bending process of the voice coil, the pressure ring can only press the free lead wire of the voice coil in the direction perpendicular to its upper surface, and cannot press the free lead wire of the voice coil in the horizontal direction

As a result, the bending angle of the free lead cannot be formed at one time

Moreover, the outlet positions of the bent free leads are irregular, which increases the difficulty of subsequent processes
