摘要： A removable case for an electronic device may have an acoustic isolation mechanism between the removable case and an acoustic component on the electronic device. The acoustic isolation mechanism may be a compressible component that may provide an acoustic seal between an inner surface of the removable case and an exterior surface of the electronic device, and may include a waterproof acoustic membrane. The waterproof membrane prevents the entry of water while reacting to sound pressure changes to acoustically couple the electronic device with sounds outside the case. The acoustic isolation mechanism may be constructed of several different materials and several different manufacturing processes.

摘要： An apparatus for a microphone and speaker is provided which provides a sealed chamber behind the speaker to prevent sound waves behind the speaker form canceling sound waves in front of the speaker. In addition, the apparatus is configured to mechanically isolate the speaker from the apparatus housing in order to improve performance of the system. A pliant material such as a damping material with a relatively linear compression characteristic, such as a thermal plastic elastomer, may be used to isolate the speaker from the apparatus housing as well as providing a relatively air tight chamber behind the speaker.

摘要： A hearing device (100) comprises a feedback-path estimation unit (108), which adaptively estimates a feedback path (FP) from an output transducer (104) to an input transducer (102). The feedback-path estimation unit (108) provides an estimation-control signal for generating an acoustic feedback-path estimation signal (FBE) having an amplitude spectrum, which has at least one first frequency band with non-zero amplitude and at least one second frequency band with zero amplitude or with a non-zero amplitude smaller than the amplitude in the first frequency band and smaller than a background-noise level in the respective second frequency band. Background noise (BN) is detected in the second frequency band while the feedback-path estimation signal (FBE) is provided. The background-noise amplitude in the at least one first frequency band is estimated for obtaining an estimate of the background-noise amplitude spectrum (BN'). The hearing device (300L, 300R) further comprises a link unit (310L, 310R), which is configured to exchange, in a binaural operation mode of the hearing device, signals with an external link unit (310R, 310L) of a second hearing device (300R, 300L) that together with the hearing device forms a binaural hearing system (300), wherein the link unit (310L, 310R) is configured to receive from the external link unit and provide to the feedback-path estimation unit (308L, 308R) noise-estimation signals (BNL', BNR') representing background-noise amplitudes (BNL, BNR) in at least one of the first frequency bands (IL, IR). The feedback-path estimation unit (308L, 308R) is configured to estimate the background-noise amplitudes (BNEL, BNER) in the corresponding at least one of the first frequency bands (IL, IR) using the received noise-estimation signals (BNL', BNR'), thereby obtaining an estimate of said background-noise amplitude spectrum to which the input transducer (102) is exposed.

摘要： A personal audio device, such as a wireless telephone, includes noise canceling circuit that adaptively generates an anti-noise signal from a reference microphone signal and injects the anti-noise signal into the speaker or other transducer output to cause cancellation of ambient audio sounds. An error microphone may also be provided proximate the speaker to estimate an electro-acoustical path from the noise canceling circuit through the transducer. A processing circuit uses the reference and/or error microphone, optionally along with a microphone provided for capturing near-end speech, to determine whether one of the reference or error microphones is obstructed by comparing their received signal content and takes action to avoid generation of erroneous anti-noise.
