Problems solved by technology

However, due to the structural characteristics of the moving coil sounding device itself, the polarization of the voice coil and diaphragm and the connection of the voice coil lead wires have always been very difficult technical problems to solve
The increase of lead wires makes it more difficult to introduce external signals into the voice coil. Each lead wire needs to be electrically connected to form a circuit for conducting external signals. The distribution and connection methods of the electrical connection points in the sounding device are more complicated.

Abstract

The invention discloses a sound production device. The sound production device comprises: a voice coil, wherein four lead ends are led out from the voice coil; an electric connecting piece, wherein the electric connecting piece comprises four inner electric connecting points and at least two outer bonding pads, the electric connecting piece is fixedly arranged in the sound production device, the outer bonding pads are exposed out of the outer surface of the sound production device, and the inner electric connecting points are electrically connected with the outer bonding pads respectively, andthe four lead ends are electrically connected with the four internal electric connection points in a one-to-one correspondence manner. One technical effect of the invention is that the electrical connection mode of the lead end and the external circuit is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of electro-acoustic transduction, and in particular relates to a sound generating device. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment, which is a transducer device that converts electrical signals into acoustic signals. The existing sound generating device includes a casing, and a magnetic circuit system and a vibrating assembly arranged in the casing. [0003] Among them, the dynamic sound generating device is widely used in consumer electronic products, and its working method can meet the requirements of speakers and earpieces of electronic products. However, due to the structural characteristics of the dynamic sounding device itself, the polarization of the voice coil and the diaphragm and the connection of the voice coil leads have always been very difficult technical problems to solve. The two voice coil wires of the voice coil o...
