  • Patent number: 10536761
    Abstract: A portable electronic device may have acoustic ports such as microphone and speaker ports. Acoustic devices such as microphones and speakers may be associated with the acoustic ports. An acoustic port may have an opening between an interior and exterior of the portable electronic device. The opening may be covered by a metal mesh. An acoustic fabric may be interposed between the metal mesh and the opening. The opening may be formed from a hole in a glass member having outer and inner chamfers. A microphone boot may be provided that forms front and rear radial seals with a housing of the device and a microphone unit respectively. The microphone boot may also form multiple face seals with the microphone unit. A speaker for the speaker port may be enclosed in a sealed speaker enclosure. The speaker enclosure may have a pressure-equalizing vent slit covered with an acoustic mesh.

  • Patent number: 10325614
    Abstract: An example implementation may involve driving an audio output module of a wearable device with a first audio signal and then receiving, via at least one microphone of wearable device, a second audio signal comprising first ambient noise. The device may determine that the first ambient noise is indicative of user speech and responsively duck the first audio signal. While the first audio signal is ducked, the device may detect, in a subsequent portion of the second audio signal, second ambient noise, and determine that the second ambient noise is indicative of ambient speech. Responsive to the determination that the second ambient noise is indicative of ambient speech, the device may continue the ducking of the first audio signal.

  • Patent number: 10178469
    Abstract: Embodiments disclosed in the present disclosure relate to vibration transducers. Such a transducer includes an electromagnet having a conductive coil. The conductive coil is configured to be driven by an electrical input signal to generate magnetic fields. The transducer further includes a magnetic diaphragm that is configured to mechanically vibrate in response to the generated magnetic fields. Additionally, the transducer includes a pair of cantilevered arms formed from damping steel. The cantilevered arms couple the magnetic diaphragm to a frame. The magnetic diaphragm vibrates with respect to the frame when the electromagnet is driven by the electrical input signal. Additionally, the pair of flexible support arms are connected to opposing sides of the magnetic diaphragm.

  • Publication number: 20180020313
    Abstract: The present disclosure relates to managing audio signals within a user's perceptible audio environment or soundstage. That is, a computing device may provide audio signals with a particular apparent source location within a user's soundstage. Initially, a first audio signal may be spatially processed so as to be perceivable in a first soundstage zone. In response to determining a high priority notification, the apparent source location of the first audio signal may be moved to a second soundstage zone and an audio signal associated with the notification may be spatially processed so as to be perceivable in the first soundstage zone. In response to determining user speech, the apparent source location of the first audio signal may be moved to a different soundstage zone.

  • Patent number: 9766481
    Abstract: An example method may be performed by a wearable computing device (WCD) that includes a bone conduction transducer (BCT). The method includes providing, to the BCT, an input signal that represents audio content. The method further includes sensing a time-varying voltage of the input signal and a time-varying current of the input signal. The method further includes determining an operating mode based on the time-varying voltage and the time-varying current. The method further includes processing the audio content according to the determined operating mode and using the processed audio content to continue providing the input signal to the BCT.

  • Patent number: 9722562
    Abstract: The present application describes signal enhancements to reduce bone conduction sensations of a wearable computing device and applications thereof. An example apparatus includes a wearable computing device comprising a bone conduction transducer (BCT) configured to receive and be driven by an audio signal, a processor, and a data storage comprising instructions executable by the processor to: (1) determine an input gain level of the audio signal at a frequency range; (2) compare the determined input gain level at the frequency range to a threshold gain level at the frequency range; (3) based on the comparison, apply a multi-band compressor (MBC) configured to process the audio signal to reduce gain in at least a portion of a mid-band frequency range of the audio signal; and (4) drive the BCT with the processed audio signal.

  • Patent number: 9699554
    Abstract: The present technology substantially reduces undesirable effects of multi-level noise suppression processing by applying an adaptive signal equalization. A noise suppression system may apply different levels of noise suppression based on the (user-perceived) signal-to-noise-ratio (SNR) or based on an estimated echo return loss (ERL). The resulting high-frequency data attenuation may be counteracted by adapting the signal equalization. The present technology may be applied in both transmit and receive paths of communication devices. Intelligibility may particularly be improved under varying noise conditions, e.g., when a mobile device user is moving in and out of noisy environments.
