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.
