SOUND GENERATION DEVICE

WIPO Patent Application WO/2020/258143

A1

Provided in the present invention is a sound generation device, comprising a basket with an accommodating space and a magnetic circuit system accommodated in the accommodating space. The magnetic circuit system comprises a magnetic conductive member fixed on the basket and magnetic steel fixedly connected to the magnetic conductive member, wherein the magnetic steel is clamped and fixed to the magnetic conductive member. One of the magnetic steel and the magnetic conductive member is provided with a fixing column, and the other is provided with a fixing hole fixedly matching the fixing column. According to the sound generation device provided in the present invention, the magnetic steel and the magnetic conductive member are clamped and fixed by means of the fixing column and the fixing hole that match each other. In the process of assembling the magnetic steel and the magnetic conductive member, the positional relationship between the upper component and the lower component can be quickly found by using a clamping structure, such that a guiding function in the assembling process is realized, the step of positioning using a tool is omitted, and the assembling efficiency is greatly improved. In addition, the precision of an assembled product is high. Therefore, the assembly precision of the magnetic circuit system can be improved, and a fluctuation range of the concentricity of a magnetic circuit is narrowed, while a high assembly efficiency is achieved.
