A communication device includes a circuit board including a plurality of contact pads and a microphone. The microphone includes a cell, a cylindrical cap contoured to define a receiving space receiving the cell, a protecting ring extending along a periphery of a bottom portion of the cylindrical cap, and a plurality of contact posts positioned on the bottom portion and contacting the plurality of contact pads to electrically connecting the circuit board and the microphone. The cylindrical cap, the protecting ring, and the contact posts are integrally formed. A height of the protecting ring is greater than that of each of the contact posts such that the protecting ring surrounds the contact pads and the contact posts to protect the microphone from dust.
