User selectable unidirectional/omnidirectional microphone housing

摘要

A housing (100) for a unidirectional microphone (102) is described which has an enclosure (104, 106) for holding the unidirectional microphone. The enclosure has a first plurality of apertures (108, 110, 114) for transmitting acoustic energy to the front and back of the unidirectional microphone. An assembly (116) is movably coupled to the enclosure which, in a first position, facilitates transmission of acoustic energy to both the front and the back of the unidirectional microphone via a first subset of the first plurality of apertures thereby facilitating unidirectional operation. In a second position the assembly inhibits transmission of acoustic energy to the back of the unidirectional microphone by blocking a second subset of the plurality of apertures thereby facilitating omnidirectional operation.
