Patent attributes
The present invention provides a sound generator, including: a vibration system including a diaphragm and a voice coil; a frame with an accommodation space, including an upper surface, a lower surface, and an inner wall; and a magnetic circuit system including a magnetic yoke and a side plate bending and extending from the bottom plate. The side plate is fixed on the inner wall, the bottom plate covers the lower surface and encloses the accommodation space. The lower surface obliquely extends in a direction close to the upper surface and forms an extension surface. The extension surface extends to an edge of the frame, one end of the extension close to the edge of the bottom plate is spaced apart from the bottom plate for forming a leakage channel communicating with the accommodation space and an outside of the speaker box.
