Abstract
An acoustic sensor assembly includes a housing having an external-device interface and a sound port to an interior of the housing. An electro-acoustic transducer and an electrical circuit are disposed within the housing. The electro-acoustic transducer separates the interior into a front volume and a back volume, where the sound port acoustically couples the front volume to an exterior of the housing. The back volume includes a first portion and a second portion. The electrical circuit is electrically coupled to the electro-acoustic transducer and to the external-device interface. One or more apertures acoustically couple the first and second portions of the back volume and are structured to shape a frequency response of the acoustic sensor assembly.
