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.
