Problems solved by technology

[0006] Due to the impact of the dome structure in the related art, there will be poor gluing or glue overflow at the joint between the voice coil and the dome, and the distance between the voice coil and the yoke will also be reduced, resulting in When the voice coil vibrates, it may hit the yoke, thereby affecting the technical problem of the performance of the sounder. The invention provides a sounder with better reliability
