Microphone and speaker arrangement in speakerphone
View Patent ↗In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. Each microphone may be mounted to the speakerphone through a microphone support. The microphone support may be made of a flexible material and have various features designed to minimize interference to the microphone (e.g., from the speaker and/or vibrations external to the speakerphone). The centrally mounted speaker may be coupled to a stiff internal speaker enclosure. The speaker enclosure may be made of a stiff, heavy material (e.g., a dense plastic) to prevent the speaker vibrations from excessively vibrating the speakerphone enclosure (which may affect the microphones).
1. A microphone support, comprising: a central mass operable to receive a microphone; two mounting strips operable to suspend the central mass; and a mounting bracket coupled to each mounting strip, wherein each mounting bracket is configured to be mounted to an enclosure and wherein the central mass comprises a top hole with a smaller diameter than a bottom hole; and wherein the central mass is configured to receive said microphone through the bottom hole with a diaphragm of the microphone closest to the top hole.
2. The microphone support of claim 1 , wherein each mounting strip has a rectangular cross section and is made of a same material as the central mass.
3. The microphone support of claim 1 , wherein each mounting bracket includes at least two holes to receive posts for mounting the microphone support to an enclosure.
4. The microphone support of claim 1 , wherein the central mass is suspended between the two mounting brackets by the two mounting strips.
5. The microphone support of claim 1 , wherein the enclosure is a speakerphone enclosure.
6. The microphone support of claim 1 , wherein the central mass, mounting strips, and mounting brackets are made of plastic.
7. The microphone support of claim 1 , wherein the central mass, mounting strips, and mounting brackets are made of a thermoplastic vulcanizate.
8. The microphone support of claim 1 , further comprising a microphone mounted in the central mass.
9. The microphone support of claim 1 , wherein at least the central mass and the mounting strips are tuned to isolate a mounted microphone from at least a portion of vibrations applied to the enclosure.
