Abstract

The invention provides a sounding device, which includes a basin frame and a vibration system and a magnetic circuit system fixed to the basin frame. The vibration system includes a diaphragm and a voice coil that drives the diaphragm to vibrate. The dome of the voice coil is stacked and the skeleton is located on the outer periphery of the dome and is spaced apart from the dome. The dome includes a main body and a limiting part extending from the main body toward the voice coil and connected to the voice coil. The outer surface of the coil and the inner surface facing the voice coil, the skeleton includes a first connecting portion and a second connecting portion bent and connected to the first connecting portion, and the first connecting portion has opposite sides in the first direction from the outer surface to the inner surface The first surface and the second surface are arranged, the first surface is flush with the outer surface, there is a gap between the main body part and the first connecting part, and the gap is filled with a glue layer to connect the ball top and the first connecting part and seal the gap. The sound generating device of the present invention can reduce the thickness of the sound generating device.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustic-electric conversion, in particular to a sound generating device. 【Background technique】 [0002] With the development of the field of acoustic-electric conversion and the improvement of user needs, in order to realize the pursuit of the sound-generating device for authentically restoring the sound source signal, in related technologies, the sound-generating device includes a vibration system, a magnetic circuit system for driving the vibration system to vibrate and sound, and a The basin frame for the installation of the vibration system and the magnetic circuit system, the vibration system includes a diaphragm and a voice coil that drives the diaphragm to vibrate, and the diaphragm includes a dome and a skeleton supporting the dome. [0003] However, in the existing sounding device, the skeleton and the dome are stacked, resulting in a relatively large thickness of the stacked part of the skel...
