When the height difference of the two fixing surfaces is in the range, the problem of uneven gas flow caused by collapse of the side sound outlet can be effectively solved. In addition, as electronic products are increasingly miniaturized, the existing sound generating device modules are all developed towards lightness and thinness, and when the height difference is within the range, the influence on the overall size of the sound generating device module is small.
