Abstract

The invention provides a sound generating device. The sound generating device of the present invention includes a basin frame, a vibration system fixed on the basin frame, and a magnetic circuit system that drives the vibration system to vibrate and produce sound. The magnetic circuit system includes a magnetic steel and a magnetic bowl that accommodates the magnetic steel. It is characterized in that the pot frame includes a first frame body, a second frame body disposed inside the first frame body, and a bottom wall connecting the first frame body and the second frame body, and the magnetic The bowl is accommodated in the second frame body, and the inner wall of the second frame body is provided with a protruding structure abutting against the outer wall of the magnetic bowl to fix the magnetic bowl. In the basin frame of the present invention, the first frame body is set to fix the vibration system, and the second frame body is set to fix the magnetic circuit system. The inner wall of the second frame is provided with a protrusion that abuts against the outer wall of the magnetic circuit system, which can increase the friction between the inner wall of the second frame and the outer wall of the magnetic circuit system, making the connection between the magnetic circuit system and the second frame more stable .

Description

【Technical field】 [0001] The invention relates to the technical field of electroacoustics, in particular to a sound generating device. 【Background technique】 [0002] With the rapid development of science and technology, in the process of rapid development of audio equipment, people's requirements for the functionality of products are getting stronger and stronger. For sound-generating devices, more and more people have put forward higher requirements for their audio performance. The sound generating device generally includes a basin frame, a vibration system and a magnetic circuit system fixed on the basin frame. The structure of the basin frame in the prior art is complicated, and the fixation with the magnetic circuit system and the vibration system is not stable. 【Content of invention】 [0003] The object of the present invention is to provide a sound generating device in which the vibration system and the magnetic circuit system are stably fixed on the basin frame. ...
