Abstract
The present invention provides a condenser microphone. In one embodiment, the condenser microphone comprises: a frame of the microphone formed of a circuit board substrate and a casing, and an amplifier device, an elastic holding component and capacitance components provided inside the microphone. One or more sound holes are provided on the circuit board substrate or the casing. The capacitance components are provided on the side with the sound holes. The amplifier device is provided on the side opposite to the side with the sound holes. The elastic holding component is provided on the side with the amplifier device or on the side with the capacitance components. The amplifier device and the capacitance components are both electrically connected to the circuit board substrate; and one or more auxiliary supporting parts are provided on the elastic holding component with the vertical height thereof being greater than that of the amplifier device and less than the distance between the capacitance components and the opposite inner wall of the microphone. When the microphone according to the present invention is sharply accelerated or under an impact, a collision between the amplifier device and the backplate caused by excessive deformation of the elastic holding component and a reduction in the resilience of the elastic holding component can be prevented with the help of the auxiliary supporting parts.
