Abstract
The present invention relates to an electret condenser microphone which comprises an exterior sidewall structure attached to a carrier. The exterior sidewall structure comprises a non-conductive base material carrying first and second electrical wiring patterns electrically connected to first and second electrical traces, respectively, of the carrier. A diaphragm holder, carrying a conductive microphone diaphragm is attached to the sidewall structure to establish electrical connection between a conductive microphone diaphragm and one of the first and second electrical wiring patterns of the sidewall structure. A conductive perforated backplate is arranged in spaced relationship to the conductive microphone diaphragm. The conductive perforated backplate is electrically connected to another one of the first and second wiring patterns of the sidewall structure. The sidewall structure may therefore be utilized to provide electrical connectivity from the conductive microphone diaphragm and from the backplate to a microphone preamplifier arranged on the carrier.
