Stuart P. Bauman - Skokie IL, US

International Classification:

H04R 1/08

Abstract:

Housings and associated mechanical and ornamental design features directed to ceiling-mounted electro-acoustical components, such as array microphones, for example, for use in a suspended ceiling, are provided. In an embodiment, a housing for a ceiling array microphone is configured for mounting the microphone within a grid system of a suspended ceiling. The housing comprises a mounting element for mounting the housing within the grid system. The mounting element includes a lipped portion positioned approximate a periphery of the housing and configured to engage the grid when the housing is mounted with the grid system.

International Classification:

H04R 19/04
H04R 1/04
H04R 1/08
H04R 19/00
H04R 19/01

Abstract:

A microphone can include a cover having a series of slits and a nest. The nest can be configured to receive a first diaphragm, a second diaphragm, and a PCB in a stacked arrangement, such that the PCB is positioned between the first diaphragm and the second diaphragm. Also, the first diaphragm can define a first plane, the second diaphragm can define a second plane, and the PCB can define a third plane and the first plane, the second plane, and the third plane can extend parallel to one another. The cover can also include slits having a first length and a second length, and the first length can be greater than the second length. The slits can extend both radially and axially.
