摘要： A microphone construction for use in a hearing aid wherein a faceplate separates a switching mechanism from a microphone having first and second acoustic ports. The first and second acoustic ports are placed into acoustic relationships with first and second acoustic opening within the faceplate by first and second acoustic passages, respectively. The switching mechanism is positionable between a first position wherein the first and second acoustic ports are in an acoustically receptive state and a second position wherein either the first or second acoustic port is in an acoustically receptive state and the other acoustic port is in an acoustically unreceptive state.

摘要： The present invention includes a compact and economical construction of a microphone wherein the housing is preferably constructed of two identical halves that form a chamber in which the microphone is retained. The housing also includes first and second acoustic passages in an acoustic relationship with the first and second ports of the microphone and extending to an exterior surface of the housing. A switching mechanism is preferably rotatably secured to the housing such that when the switching mechanism is in a first position, the first and second passages are in an acoustic receptive state and when rotated to a second position only one of the acoustic passages is in an acoustic receptive state.
