ABSTRACT:
A microphone assembly having a housing, a transducer, and an electronic circuit. The housing has an opening, and the transducer is disposed within that opening. The electronic circuit covers the opening such that the transducer is surrounded by at least the electronic circuit and the housing. The electronic circuit includes a substrate and an amplifier for amplifying the electrical signal into an amplified electrical signal which is coupled to a connection means. The connection means provides a direct electrical connection between the electronic circuit and a receiver. The amplifier is mounted on the substrate and disposed on a side of the substrate of the electronic circuit facing the transducer. The receiver is disposed on a side opposite the side and outside the housing.
