Problems solved by technology

[0004] However, in the sound-generating device in the related art, the upper surface of the steel sheet is a complete plane, and the air-permeable spacer is attached and fixed on the flat surface of the steel sheet, thus causing the air-permeable spacer to protrude out of the flat surface. On the above-mentioned steel sheet, the additional product height is occupied, which reduces the utilization rate of the height and space of the single unit
