SYSTEMS AND METHODS FOR LOCATING AN ERROR MICROPHONE TO MINIMIZE OR REDUCE OBSTRUCTION OF AN ACOUSTIC TRANSDUCER WAVE PATH
First Claim
1. An apparatus comprising:
- an acoustic transducer comprising a diaphragm having a front and a back, the diaphragm configured to mechanically vibrate in response to an audio signal input to the acoustic transducer, thereby producing sound from the front of the diaphragm;
a housing configured to mechanically support the acoustic transducer such that the front faces an exterior of the housing and the back faces an interior of the housing;
a microphone disposed in the interior of the housing for sensing combined sound produced by the acoustic transducer and ambient sound proximate to the acoustic transducer; and
an acoustical conduit coupled to and extending from the microphone and passing adjacent to the acoustic transducer such that the microphone senses sound proximate to the front of the diaphragm.

Abstract
An apparatus may include an acoustic transducer, a housing, a microphone, and an acoustical conduit. The acoustic transducer may include a diaphragm having a front and a back, the diaphragm configured to mechanically vibrate in response to an audio signal, thereby producing sound from the front of the diaphragm. The housing may be configured to mechanically support the acoustic transducer such that the front faces an exterior of the housing and the back faces an interior of the housing. The microphone may be disposed in the interior of the housing and may be configured to sense combined sound produced by the acoustic transducer and ambient sound proximate to the acoustic transducer. The acoustical conduit may be coupled to and extend from the microphone and pass adjacent the acoustic transducer such that the microphone senses sound proximate to the front of the diaphragm.

8. A method comprising:
-
providing an acoustic transducer comprising a diaphragm having a front and a back, the diaphragm configured to mechanically vibrate in response to an audio signal input to the acoustic transducer, thereby producing sound from the front of the diaphragm; mechanically supporting the acoustic transducer in a housing such that the front faces an exterior of the housing and the back faces an interior of the housing; disposing a microphone in the interior of the housing for sensing combined sound produced by the acoustic transducer and ambient sound proximate to the acoustic transducer; and coupling an acoustical conduit to the microphone such that the acoustical conduit extends from the microphone and passes through the acoustic transducer such that the microphone senses sound proximate to the front of the diaphragm. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An apparatus comprising:
-
an acoustic transducer configured to produce sound in response to an audio signal input to the acoustic transducer; a first acoustical conduit coupled to and extending from the acoustic transducer for acoustically conducting sound from the acoustic transducer to an end of the acoustical conduit opposite the acoustic transducer; a microphone sensing combined sound produced by the acoustic transducer and ambient sound proximate to the end of the first acoustical conduit opposite the acoustic transducer; and a second acoustical conduit coupled to and extending from the microphone and to a location proximate to the end of the first acoustical conduit opposite the acoustic transducer such that the microphone senses sound proximate to the end of the first acoustical conduit. - View Dependent Claims (16, 17, 18, 19, 20, 21)
