ACOUSTICAL AND ELECTRICAL SWITCH FOR A DIRECTIONAL MICROPHONE |
摘要 |
A combination acoustical and electrical switch for a multi-port microphone in a hearing aid device that provides selectivity between a directional mode and an omnidirectional mode while also providing sensitivity adjustment for each of the modes. The switch includes a switch body having a port aperture therein in communication with one of the ports of the microphone, and a switch actuator moveably connected to the switch body and moveable to a first position wherein the port aperture is generally unobstructed by the actuator and a second position wherein the actuator covers the port aperture. The actuator is in communication with sensitivity optimization circuitry of the hearing aid to provide unidirectional sensitivity optimization in the first position and omnidirectional sensitivity optimization in the second position.
