description A microphone with back chamber includes an outer casing, a sound head unit inserted in the outer casing, an airtight unit, and a damping material. The sound head unit includes a carrier and a sound receiving module connected to the carrier for receiving sound. The carrier has an opening extending in an axial direction from one end opposite to the sound receiving module. The airtight unit includes a shock-absorbing member connected with the outer casing and the carrier of the sound head unit and an airtight member in airtight contact with the outer casing. The airtight member, the shock-absorbing member, the outer casing and the carrier define an airtight back chamber. The back chamber is provided to generate a pneumatic wave when a mechanical vibration wave is transmitted to the sound head unit through the outer casing. The damping material seals the opening and functions to change the phase of the pneumatic wave passing therethrough. As a result, the arrangement of the back chamber and the airtight member al
