Problems solved by technology

The struts in the prior art fluctuate up and down in the axial direction in a wavy shape, and the materials are mostly fiber materials. The struts with this structure and material not only occupy a large space in the height direction of the sounding device, but also, Limited by the material, it is difficult to make the Kms (mechanical stiffness) of the damper very small. When the vibration displacement of the sounding device is large, the compliance provided by the damper becomes worse, and it is difficult to reduce the stiffness of the monomer. F0
In addition, the existing damper is easily deformed in a high temperature and high humidity environment, its hardness changes, and its fatigue resistance is relatively poor

Abstract

The invention discloses a centering disk and a sounding device, the centering disk comprises a first connecting part, a planar elastic part and a second connecting part, and one side of the first connecting part is configured to be cooperatively connected with a voice coil of the sounding device; the end part of the first connecting part bends and extends towards the other side in an S shape to form the planar elastic part, and the planar elastic part and the first connecting part are in the same plane; the second connecting part is connected to one end, far away from the first connecting part, of the plane elastic part, and the second connecting part is configured to be fixedly connected in the sound production device; the centering disk is of a linear structure formed by integrally winding.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, and more specifically, to a damper and a sounding device. Background technique [0002] With the rapid development of science and technology, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to audio playback, but more requirements are put forward for the reliability of audio equipment. In audio equipment, a sound generating device is a commonly used electronic component, which is mainly used for playing audio signals, and its reliability directly affects the function of the audio device with the sound generating device. [0003] The centering strut is one of the basic components of the sounding device. Its main function is to ensure the correct position of the voice coil in the magnetic gap, to keep the vibration system reciprocating in the axial direction and to provide the vibration system when the voic...
