Audible device

Abstract

An audible device includes a vibration system, a magnetic system, a basin rack and electrical connector. The vibration system comprises a voice coil, The voice coil leads out the voice coil leads, Anelectrical connection includes a centering diaphragm and an electrically conductive assembly, the centering diaphragm is integrally molded with the conductive module, A conductive assembly includes afirst portion and a second portion injection molded with a centering diaphragm, the first portion and the second portion are located at two ends of the centering diaphragm, a second portion of the conductive assembly is bonded to a side wall of the voice coil, a first portion of the conductive assembly is bonded to the back of the basin frame, the voice coil leads are bonded to the second portionof the conductive assembly, The voice coil lead soldered on the second part of the conductive assembly is electrically connected with the centering diaphragm, and the first part of the conductive assembly is electrically connected with the external wiring through the external pad on the first part, or the technical scheme of integrally molding the centering diaphragm with the conductive assembly and the basin frame can effectively avoid the bonding problem of the conductive assembly and the basin frame.

Description

technical field [0001] The invention relates to a sounding device, in particular to a sounding device, which belongs to the technical field of electronic components. Background technique [0002] People always hope that the volume can be louder when using smart terminals such as mobile phones, and because of this demand, many new technologies have been developed, such as smart power amplifiers. In order to achieve a louder sound for the existing speakers, the vibration amplitude must be increased under the existing size conditions, but the increase of the vibration amplitude will bring many problems to the speakers of the existing structure, and the first one is the rocking vibration under the large amplitude Noise problems generated. [0003] Existing technical solutions: (1) Using FPC instead of the voice coil lead-out solution, the structure is more complicated, and the amplitude cannot be greatly improved (the amplitude of existing FPC products is increased to 0.4mm, bu...

AI Technical Summary

Problems solved by technology

[0007] (1) Thoroughly solve the problem that the centering diaphragm is not easy to bond with the voice coil and the basin frame, and at the same time solve the problem of bonding firmness;

[0008] (2) The welding and bonding process of the voice coil lead is simpler and more efficient, which effectively solves the problem of disconnection;
