  • Patent number: 10440482
    Abstract: A MEMS microphone may include a backplate comprising first and second electrodes electrically isolated from one another and mechanically coupled to the backplate in a fixed relationship relative to the backplate and a diaphragm configured to displace relative to the backplate as a function of sound pressure incident upon the diaphragm, the diaphragm comprising third and fourth electrodes electrically isolated from one another and mechanically coupled to the diaphragm in a fixed relationship relative to the diaphragm such that the third and fourth electrodes displace relative to the backplate as a function of sound pressure incident upon the diaphragm. The first and third electrodes may form a first capacitor and the second and fourth electrodes may form a second capacitor, the capacitance of each which may be a function of the displacement of the diaphragm, and each of which may be biased by an alternating-current voltage waveform.

  • Patent number: 10405128
    Abstract: To resolve a problem that a listener feels that sense of localization and sense of connecting with the other channels are lost in case that the listener listens to an audio that is output from a ceiling reflection type speaker in an audio processing device that outputs an analog audio signal to speakers including the ceiling reflection type speaker that makes the audio reflect at a ceiling. A DSP 5 performs low-pass filter processing that extracts low frequency component from a digital audio signal, high-pass filter processing that extracts high frequency component from the digital audio signal, delay processing that delays the low frequency component of the digital audio signal that is extracted by the low-pass filter processing, and composition processing that composes the low frequency component of the digital audio signal that is delayed by the delay processing and the high frequency component of the digital audio signal that is extracted by the high-pass filter processing as audio signal processing.

  • Patent number: 10313218
    Abstract: A system and method receives one or more captured signals through a captured audio path and produces one or more playback signals through a playback audio path. The system and method executes one or more signal processing functions and measures the delays within the playback audio path and captured audio path during operation of the one or more signal processing functions. The system and method stores the measured delays in a memory and compensates the one or more signal processing functions for the playback delay and the capture delay.

  • Patent number: 10283135
    Abstract: Suppression of tapping noise caused by tapping an acoustically coupled touchscreen. When a tapping event is detected on the touchscreen, a tapping noise suppressor is alerted of the event, and responds by at least temporarily mitigating the tapping noise in the audio stream. The suppression occurs temporarily for at least part of the duration of surge in audio levels that occurs as a result of the tapping event, and in a manner that reduces the psychoacoustic impact on the conversation. Suppression may be performed by first placing the tapping noise suppressors in an alert mode when a tapping event occurs. The tapping noise suppressor then monitors the audio stream generated by the microphone for the beginning of the tapping event—which will be represented in the form of a surge in volume. The tapping noise suppressor then temporarily applies the suppression window.

  • Patent number: 10231046
    Abstract: An audio system includes a transducer assembly, an audio sensor, and a controller. The transducer assembly is coupled to a back of an auricle of an ear of the user. The transducer assembly vibrates the auricle over a frequency range to cause the auricle to create an acoustic pressure wave in accordance with vibration instructions. The acoustic sensor detects the acoustic pressure wave at an entrance of the ear of the user. The controller dynamically adjusts a frequency response model based in part on the detected acoustic pressure wave, updates the vibration instructions using the adjusted frequency response model, and provides the updated vibration instructions to the transducer assembly.

  • Patent number: 10176795
    Abstract: The present invention relates to a method of noise reduction including the steps of filtering reference signals and representing noise by an adaptive filter comprising adaptive filter coefficients to obtain actuator driving signals, outputting the actuator driving signals by loudspeakers to obtain loudspeaker signals. The method further includes detecting the loudspeaker signals by microphones and filtering the reference signals by estimated transfer functions representing the transfer of the loudspeaker signals output by the loudspeakers to the microphones to obtain filtered reference signals. The method further includes updating the filter coefficients of the adaptive filter based on the filtered reference signals and based on the previously updated filter coefficients of the adaptive filter multiplied by leakage factors.

  • Patent number: 10063249
    Abstract: A D/A converter converts digital audio data DIN into analog differential audio signals VP and VN. A differential to single-ended conversion circuit converts the differential audio signals VP and VN into a single-ended audio signal VSE. A volume circuit receives the single-ended audio signal VSE, and amplifies the single-ended audio signal VSE with a gain that corresponds to a volume value. A reference voltage source generates a reference voltage VREF commonly referred by the differential to single-ended conversion circuit and the volume circuit. In a calibration operation, a calibration circuit controls the D/A converter so as to shift at least one from among the differential audio signals VP and VN such that the difference between the output voltage VSE of the differential to single-ended conversion circuit and the reference voltage VREF approaches zero.
