Abstract

Disclosed are a centring disk and a sound production device, the centring disk comprising a first fixing part and a third fixing part that are used for being connected and fixed to an acoustic component, wherein the first fixing part is configured to be a cylindrical part and is located in the middle of the centring disk; and the third fixing part is located on the edge of the centring disk, a plurality of elastic arms are arranged between the first fixing part and the third fixing part at intervals, and a window is formed between two adjacent elastic arms. One technical effect of the present invention lies in that a lead wire led out by a voice coil can pass through a second window and a first window on the centring disk, such that the height of the structure is reduced, bending of the lead wire is reduced, and the service life is prolonged.

Description

technical field [0001] The present invention relates to the technical field of acoustic-electric conversion, and more particularly, to a damper and a sound-generating device. Background technique [0002] In existing sound generating devices, electro-acoustic conversion is performed through an internal system structure. The centering struts set in it have the function of supporting and stabilizing the structure. The existing centering struts are generally fixed on the frame through the outer ring, and the inner ring and the voice coil skeleton are fixed to limit the radial movement of the voice coil skeleton. . And, it plays the role of bearing. [0003] The existing damper is assembled in the sound-generating device, and the brocade wire drawn from the voice coil needs to bypass the damper and lead out from the space of the vibration system to communicate with the external circuit. Such a structure increases the height of the overall structure of the sound generating dev...
