    Abstract: A computer system having a loudspeaker mounted on a main logic board by a hermetic seal, is disclosed. More particularly, embodiments of the computer system include an acoustic cavity defined between the loudspeaker, the main logic board, and the hermetic seal. Embodiments of the computer system may include a compressible seal separated from the hermetic seal by the loudspeaker and/or the main logic board. The compressible seal may define an acoustic channel and the loudspeaker may emit sound in a high frequency range through the acoustic channel toward a system exit. Other embodiments are also described and claimed.

    Abstract: A method of detecting a user's voice activity in a mobile device is described herein. The method starts with a voice activity detector (VAD) generating a VAD output based on (i) acoustic signals received from microphones included in the mobile device and (ii) data output by an inertial sensor that is included in an earphone portion of the mobile device. The inertial sensor may detect vibration of the user's vocal chords modulated by the user's vocal tract based on vibrations in bones and tissue of the user's head. A noise suppressor may then receive the acoustic signals from the microphones and the VAD output and suppress the noise included in the acoustic signals received from the microphones based on the VAD output. The method may also include steering one or more beamformers based on the VAD output. Other embodiments are also described.

    Abstract: A portable electronic device having an outer case having a substantially planar face in which a microphone associated acoustic port is formed. The device also has a micro-electro-mechanical system (MEMS) microphone positioned within the outer case, the MEMS microphone having a diaphragm facing the microphone associated acoustic port. An acoustic mesh is positioned between the front face of the outer case and the diaphragm, the acoustic mesh having a non-linear acoustic resistance so as to minimize an effect of an incoming air burst on the diaphragm. Other embodiments are also described and claimed.
