Sound production device and electronic terminal

Abstract

The invention discloses a sound production device. The device comprises a shell, the shell is provided with an accommodating space, and a magnetic circuit system is installed in the accommodating space; a voice coil comprises a voice coil body and a framework; a conductive piece is provided with a first connecting part fixed with the voice coil, a second connecting part fixed with the shell, and an elastic piece positioned between the first connecting part and the second connecting part; the conductive piece is combined on the voice coil body, and the magnetic circuit system is provided with an avoiding part corresponding to the conductive piece; the voice coil is provided with an inner conduction structure, the shell is provided with an outer conduction structure which is conducted with an external circuit, and after being electrically connected with the inner conduction structure, the first connecting part of the conductive part penetrates out of the avoiding part of the magnetic circuit system, extends to the shell and is electrically connected with the outer conduction structure. The conductive part of the sound production device is arranged in the root area of the voice coil body, so that the sound production device has good axial compliance, and radial offset and swing vibration are reduced.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a sound generating device. Background technique [0002] 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 voice coil is stressed. Elasticity during reciprocating motion. [0003] At present, the traditional sounding device, such as in the loudspeaker device, usually fixes the strut on the voice coil frame, and the strut is in the shape of an elastic wave. The structure of the traditional strut makes the vibration of the large horn The height in the direction increases; in addition, the traditional sounding device needs to set additional silk wires to realize the electrical connection between the voice coil and the external circuit, and ...

Problems solved by technology

[0003] At present, traditional sound-generating devices, such as large speaker devices, usually fix the struts on the voice coil frame, and the struts are in the shape of spring waves. The structure of the traditional struts makes it vibrate along the loudspeaker The height in the direction increases; in addition, the traditional sounding device needs to be additionally equipped with brocade wires to realize the electrical connection between the voice coil and the external circuit, and the brocade wires need to occupy the internal space of the sounding device during the routing process
