  • Condenser microphone
    Patent number: 8693712
    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.

  • Spacer for a capacitive microphone and capacitive microphone with the same
    Patent number: 8654996
    Abstract: The present invention relates to a spacer for a capacitive microphone and a capacitive microphone with such spacer, in which the spacer is mounted between polar plates and vibrating diaphragm of the microphone and the spacer comprises at least one insulating layer and at least one conductive layer bonded with the insulating layer. With the above-mentioned structure, static electricity is effectively prevented from occurring or storing during manufacturing process of the spacer and meanwhile, disadvantages such as difficult processing, high cost and tendency to increase parasitic capacitance while making spacer with metal sheet are overcome.
