Telephone receiver with improved structure

Abstract

The invention discloses a telephone receiver with an improved structure. The telephone receiver comprises an electromagnetic shielding shell, a vibrating diaphragm assembly and an electromagnetic conversion device, wherein the electromagnetic conversion device comprises an armature, a coil and permanent magnets; the armature comprises a main body and side wings; the main body is a long strip shaped board with a head part and a tail part; the side wings are symmetrically arranged at the two sides of the head part and bent downwards; the tail part is bent downwards; the bent main body is a U-shaped component; the coil is sleeved on the bent part of the U-shaped component and fixedly connected with the side wings; and the permanent magnets are symmetrically arranged at the upper side and the lower side of the tail part and are fixedly arranged at the inner side of the head part and the inner side of a bottom plate respectively. According to the telephone receiver with the improved structure disclosed by the invention, the process that an iron core is extensively adopted as a magnetic loop by a magnetic conversion mechanism in the existing telephone receiver is avoided; the improved armature and the shell body are combined to form an enclosed magnetic loop; and the production cost is reduced while the magnetic conductivity of the armature is sufficiently utilized.

Description

technical field [0001] The present invention relates to a sounding device, in particular to a receiver with an improved structure. Background technique [0002] The receiver is an electro-acoustic device that converts audio electrical signals into sound signals without sound leakage. It is widely used in communication terminal products to realize audio playback, mainly in mobile phones, earphones and hearing aids. With the continuous improvement of living standards, people's mobile phones, earphones and hearing aids are becoming lighter and thinner. Especially in the field of earphones and hearing aids, users tend to accept more miniaturized products for their convenience. life. [0003] The magnetic conversion mechanism is an important part of the receiver. It is assembled from multiple components. In order to reduce the volume of the magnetic conversion mechanism, the components that assemble the magnetic conversion mechanism must be miniaturized and improved, but miniatu...

Problems solved by technology

[0003] The magnetic conversion mechanism is an important part of the receiver. It is assembled from multiple components. In order to reduce the volume of the magnetic conversion mechanism, the components that assemble the magnetic conversion mechanism must be miniaturized and improved, but miniaturization will inevitably bring processing accuracy. and the improvement of processing difficulty; especially the iron core unit in the receiver, because it must have a closed frame structure, it will increase the processing difficulty after miniaturization, and the processing accuracy is not easy to guarantee, followed by production costs a substantial increase in
