MULTI-MICROPHONE PORTING AND VENTING STRUCTURE FOR A COMMUNICATION DEVICE |
| 摘要 |
A microphone porting and venting assembly (100) is formed of a remote support substrate (118) providing a (130) acoustically resistive element with dedicated venting cavities (132) along with an external baffle (220) providing acoustic channels (212, 214, 216) which further provide water drainage and external sound sampling points (222, 224, 226). The microphone porting and venting assembly (100) is well suited waterproof, noise cancelling microphone systems. |

1. A microphone porting and venting assembly, comprising:
a housing comprising a plurality of separated elongated air passageways (124) formed therein for each of a plurality of microphones (102), the plurality of microphones being mounted to a printed circuit board; a waterproof and non-permeable membrane (126) coupled over the plurality of internal elongated air passageways; and a remote support substrate (118) coupled to the plurality of separated elongated air passageways (124), the remote support substrate (118) providing a single acoustic resistive venting element (130) and separate venting cavities (132) for each of the plurality of microphones (102). |
