Since the sealing member 40 is further provided with the air vent 43 in a protruding manner, and the air vent 43 is staggered with the air inlet 111 on the connecting portion 11, the risk that the liquid enters the mounting groove 12 to damage the PCB 30 is reduced. Meanwhile, as the lower edge of the notch 1121 on the air inlet pipe 112 is higher than the bottom of the connecting part 11, the risk that liquid enters the air inlet pipe 112 of the microphone 31 to reach the microphone 31 and damage the microphone 31 is reduced.
