Publication number: 20240144906Abstract: Aspects of the subject technology provide for generation of a self-voice signal by an electronic device that is operating in an active noise cancellation mode. In this way, during a phone call, a video conference, or while listening to audio content, a user of the electronic device may benefit from active cancellation of ambient noise while still being able to hear their own voice when they speak. In various implementations described herein, the concurrent self-voice and automatic noise cancellation features are facilitated by accelerometer-based control of sidetone and/or active noise cancellation operations.Type: ApplicationFiled: January 10, 2024Publication date: May 2, 2024Inventors: Yang LU, Andrew P. BRIGHT, Fatos MYFTARI, Vasu IYENGAR

Publication number: 20230379624Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may include speaker control circuitry for a speaker. The speaker control circuitry may include multiple parallel prediction blocks that share a single look-ahead delay, and that feed, in parallel, a single controller. The single controller can generate a joint modification to an audio signal based on the parallel outputs of the prediction blocks. The joint modification can then be applied to the audio signal to generate a speaker-protection audio signal that can be output by the speaker. The speaker control circuitry may also include a system modeler that models the speaker system of the electronic device based on feedback measured physical characteristics. In this way, a reduced control safety margin can be achieved by more accurate model predictors, which can allow the controller to safely drive the speaker system to its full capability.Type: ApplicationFiled: May 20, 2022Publication date: November 23, 2023Inventors: Thomas M. JENSEN, Andrew P. BRIGHT, Ariel A. MASSIAS, Ethan R. DUNI, Hannes BREITSCHAEDEL, Max RASMUSSEN

Publication number: 20220279305Abstract: Disclosed are systems and methods for automatically transitioning between communication modes of wearable audio output devices based solely on acoustic analysis. The audio output devices may operate in one of three electroacoustic modes. In the transparency mode, an audio output device may pass through the speech signal of a nearby user. In the peer-to-peer mode, the audio output device may establish a direct low-latency radio frequency (RF) link to another audio output device. In the telephony mode, the audio output device may communicate with another audio output device using networked telephony. The disclosed methods and systems perform acoustic analysis of the near-field speech signal of a local wearer of the audio output device and the far-field speech signal of a remote talker to determine the best mode for the audio output device to use and to seamlessly transition between the modes as the acoustic environment between the wearers changes.Type: ApplicationFiled: February 22, 2022Publication date: September 1, 2022Inventors: Jonathan D. Sheaffer, Martin E. Johnson, Andrew P. Bright

Patent number: 10848859Abstract: A method for mitigating noise caused by a loudspeaker in an audio device. The method obtains an audio signal for driving the loudspeaker. The method obtains a system model of the audio device that represents a modeled physical characteristic of the audio device, and determines whether a noise level of loudspeaker induced acoustic noise is greater than a desired sound level by analyzing the audio signal according to the system model, where the noise level and the desired sound level are characterized at the listener's position in an acoustic environment. The method, in response to determining that the noise level is greater than the sound level, processes the audio signal to cause a reduction of the noise level.Type: GrantFiled: January 25, 2019Date of Patent: November 24, 2020Assignee: Apple Inc.Inventors: Hannes Breitschaedel, Thomas M.

Patent number: 9681228Abstract: A micro speaker having a capacitive sensor to sense a motion of a speaker diaphragm, is disclosed. More particularly, embodiments of the micro speaker include a conductive surface of a diaphragm facing conductive surfaces of several capacitive plate sections across a gap. The diaphragm may be configured to emit sound forward away from a magnet of the micro speaker, and the capacitive plate sections may be supported on the magnet behind the diaphragm. In an embodiment, the gap provides an available travel for the diaphragm, which may be only a few millimeters. A sensing circuit may sense capacitances of the conductive surfaces to limit displacement of the diaphragm to within the available travel.Type: GrantFiled: April 6, 2015Date of Patent: June 13, 2017Assignee: Apple Inc.Inventors: Christopher Wilk, Alexander V.
