Abstract

An embodiment includes an array microphone system (104) comprising several concentric nested rings of variable size on a substrate (107a, 107b) arranged around a center point of the substrate (107a, 107b) Circle of multiple microphones (106). Each ring includes a subset of the plurality of microphones (106) positioned at predetermined intervals along a circumference of the ring. Embodiments also include a microphone assembly (100) including an array microphone (104) and a housing (102) configured to support the array microphone (104) and sized and shaped to be installable in a suspended ceiling in place of at least one of the plurality of ceiling tiles included in said suspended ceiling. The front of the housing (102) includes an acoustically permeable screen (18) having a size and shape substantially similar to the at least one of the plurality of ceiling tiles.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 14 / 701,376, filed April 30, 2015, which is incorporated herein in its entirety. technical field [0003] The present application generally relates to an array microphone system and a method of assembling the same. In particular, the present application relates to an array microphone capable of fitting into a ceiling tile of a suspended ceiling and providing 360 degree audio pickup with an overall directivity index optimized across the speech frequency range. Background technique [0004] Conferencing environments, such as board meetings, video conferencing situations, and the like, may involve the use of microphones to capture sound from audio sources. For example, the audio source may include a human speaker. The captured sound can be broadcast to listeners via speakers in the environment, television broadcasts, and / or Internet broadcasts. [...
