Because the height of the first side wall 111' is relatively low, there is also a sounding hole 13' on it, so that the slightly larger sounder 2' can only use the side sounding method to make the sound pass through the sounding hole 13'. 2' is built into the sounder housing 1', so that the sounding device 21' faces the connecting wall 12'.

However, the side-firing method can only make the electronic equipment using the micro-sounder assembly 100' have a good low-frequency working effect, and its high-frequency working effect is poor.

Therefore, it is really necessary to improve the micro-sounder assembly in the related art to expand its operating frequency range.

【Content of utility model】
