Patent number: 12293753Abstract: 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: GrantFiled: January 10, 2024Date of Patent: May 6, 2025Assignee: Apple Inc.Inventors: Yang Lu, Andrew P.

Patent number: 12231852Abstract: Hearing instruments, such as hearing aids, may improve a quality of presented audio through the use of a binaural application, such as beamforming. The binaural application may require communication between the hearing instruments so that audio from a left hearing instrument may be combined with audio from a right hearing instrument. The combining at a hearing instrument can require synchronizing audio sampled locally with sampled audio received from wireless communication. This synchronization may cause a noticeable delay of an output of the binaural application if the latency of the wireless communication is not low (e.g., a few samples of delay). Presented herein is a low-latency communication protocol that communicates packets on a sample-by-sample basis and that compensates for delays caused by overhead protocol data transmitted with the audio data.Type: GrantFiled: December 20, 2023Date of Patent: February 18, 2025Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Ivo Leonardus Coenen, Dennis Wayne Mitchler

Patent number: 12225340Abstract: A sonic ranging method for a mobile phone and a wireless earphone. Firstly, the mobile phone performs an acoustic response test on the wireless earphone. The mobile phone generates a first audio sequence at a first time slot. The wireless earphone recognizes the first audio sequence to generate a second audio sequence. When the mobile phone recognizes the second audio sequence, the mobile phone estimates a length of elapsed time according to the time difference between a current time slot and the first time slot. When the mobile phone obtains the length of elapsed time, a distance between the wireless earphone and the mobile phone may be determined according to a delay compensation parameter and the length of elapsed time. Various potential applications can be implemented based on the invention without the needs for additional hardware circuits in the mobile phone.Type: GrantFiled: December 1, 2022Date of Patent: February 11, 2025Assignee: LUXSHARE ELECTRONIC TECHNOLOGY (KUNSHAN) LTD.Inventors: ZhiZhong Zhang, QingSong Yu, RuiBao Liu
