Abstract

The invention discloses a sound production unit which comprises a support, a vibrating diaphragm, a voice coil, a damper and a magnetic circuit assembly, wherein the damper comprises a supporting member connected with the vibrating diaphragm and an elastic member connected with the supporting member, one end of the elastic member is connected with the supporting member, the elastic member is provided with a baffle plate, and the bottom of the support is provided with a mounting port. The baffle plate penetrates through the mounting port and is connected with the bottom of the support in a clamped mode, a receding groove is further formed in the outer side of the bottom of the support, and the baffle is arranged in the receding groove and elastically abuts against the receding groove. Compared with the prior art, the damper is very simple in structure and easy and convenient to install, does not cause interference to the voice coil lead, can play a good limiting effect on the vibrating diaphragm and the voice coil, avoids radial movement of the voice coil, and ensures good tone quality.

Description

technical field [0001] The invention relates to the technical field of acoustic-electric conversion, in particular to a sounding unit. Background technique [0002] The sound unit is a common electro-acoustic conversion device in the field of electro-acoustics. It plays an extremely important role in the electro-acoustic system, but it is very fragile. Its working principle is based on Faraday's law, relying on the magnetic field to drive the movement of the voice coil , the voice coil drives the diaphragm to vibrate to produce sound, and the damper is an indispensable part of the sound unit. It is fixed on the bracket through the outer edge, and the inner ring and the voice coil are bonded and fixed, so as to keep the voice coil moving in the magnetic gap without touching the iron sheet, magnet or bracket; however, the existing damper is very inconvenient to install , and in the elongated miniature sounding unit, the existing damper tends to vibrate asynchronously on both ...
