The number of fasteners 150 and the number of cushions 130 can be set according to the size of the circuit board 141 to meet the fixing requirements in practice. The plurality of fasteners 150 can be disposed in a staggered manner, and each pair of fasteners 150 can have a displacement d. However, the present application is not limited thereto, and in other embodiments, the plurality of fasteners 150 can be disposed in an aligned manner. In addition, the cushion 130 is not limited to a ring-shaped washer, and can also be a cushion 130 whose XY plane area is several times larger than the cross-sectional area of the fastener 150. In other embodiments, the cushion 130 can be a single structural member and extend above the circuit board 141 to cover a large area of the circuit board 141.
[0019] In addition, the shell 110 can be made of a hard material, including but not limited to plastic or plastic-containing materials, which can have a blind hole 110H. The buffer 120 and the cushion 130 can be made of a soft material, including but not limited to rubber or rubber-containing materials, and the buffer 120 can have a through hole 120H, and the cushion 130 can have a through hole 130H.

The fastener 150 can be made of a hard material, including but not limited to metal and plastic, and the fastener 150 is disposed through the through hole 120H of the buffer 120, the through hole 141H of the circuit board 141 and the through hole 130H of the cushion 130 and is fixed in the blind hole 110H of the shell 110. In one embodiment, the hardness of the cushion 130 can be greater than or equal to the hardness of the buffer 120, but the present application is not limited thereto.
[0020] The buffer 120 can have a recess 120R. The microphone module 142 can be accommodated in the recess 120R and abut the buffer 120. The buffer 120 can further have a sound receiving channel 120CN, and the shell 110 can have a sound receiving opening 110OP, the sound receiving channel 120CN and the sound receiving opening 110OP are aligned and communicated in the longitudinal direction (Z-axis). The sound receiving opening 110OP is not limited to being located on the side of the shell 110, and can also be located on the top of the shell 110. Figure 2 and Figure 5The cross-sectional profile of the illustrated fold line can also be a cross-sectional profile extending only diagonally. The sound channel 120CN extends to the recess 120R. The sound opening 110OP is in communication with the microphone module 142 via the sound channel 120CN, so that the microphone module 142 can receive sound from the external environment of the housing 110.
