Patent ID: 8526652

Claim:
A receiver assembly for generating acoustic signals and for inflating a membrane located within an ear canal, comprising: a first receiver including: a housing, an inflation port in the housing, a first diaphragm for generating a first acoustic signal in response to a sound-input audio signal during a normal operational mode and a second acoustic signal in response to an inflation audio signal during an inflation mode, a first front volume within the housing for transmitting the generated first and second acoustic signals within the ear canal, and a first back volume within the housing in direct communication with the inflation port and separated from the first front volume by the first diaphragm, the first back volume, during the inflation mode, expelling air through the inflation port for inflating the membrane; a second receiver including: a second diaphragm for generating a cancellation acoustic signal in response to a cancellation audio signal during the inflation mode, and a second front volume for transmitting the generated cancellation acoustic signal within the ear canal; and at least one sound port coupled to the first and second receivers and directing the acoustic signals from the first and second front volumes within the ear canal; wherein, during the inflation mode, the cancellation acoustic signal at least partially cancels the second acoustic signal to reduce a noise effect that is associated with the inflation mode.
