An electronic device may be configurable to operate in a scrambling mode and a non-scrambling mode while processing chat audio and microphone audio for a first player participating in an online multiplayer game via a game console. While operating in the non-scrambling mode, the electronic device may be configured to transmit the microphone audio to the game console without scrambling the microphone audio. While operating in the scrambling mode, the electronic device may be configured to scramble the microphone audio and transmit the scrambled microphone audio to the game console. The electronic device may be operable to select a scrambling key used to scramble the microphone audio based on a signal received by the electronic device that indicates a role of the player in the online multiplayer game. The role of the player may correspond to which of two or more opposing teams the first player is a member of in the online multiplayer game.

A processing system obtain signals that are generated by or generated based on sensors that are included in one or more hearing instruments. Additionally, the processing system determine, based on the signals, whether a posture of a user of the hearing instruments is a target posture. The processing system generate information based on the posture of the user.

A vibration apparatus may include a vibration device and an adhesive member at a surface of the vibration device. A modulus of the vibration device may be equal to a modulus of the adhesive member or may be greater than the modulus of the adhesive member.

The technology of this application relates to a laser microphone, including a diaphragm, a laser device, a control circuit, a self-mixing signal obtaining apparatus, and a signal processing circuit. The laser device is configured to emit light to the diaphragm and receive a feedback light signal from the diaphragm, and the feedback light signal interferes with laser in a resonant cavity of the laser device to obtain a self-mixing light signal. A distance between the laser device and the diaphragm ranges from 30 to 300 m. The control circuit is connected to the laser device, and is configured to drive and control the laser device to emit light. The self-mixing signal obtaining apparatus is connected to the laser device, and is configured to obtain a target voltage signal related to the self-mixing light signal.

An audio output device, a method for eliminating sound leakage, and a storage medium are provided in the disclosure. The audio output device includes a processor, a first speaker, and a second speaker. The processor is configured to generate a second audio file based on a first audio file and a parameter adjustment value. The processor is configured to control the first speaker to play the first audio file to generate a first audio and synchronously control the second speaker to play the second audio file to generate a second audio. The first audio is transmitted to an ear of a user for the user to listen, and the second audio is used to eliminate an audio leaked to an outside of the audio output device during transmission of the first audio to the ear of the user.

Apparatus including a processor configured to: obtain at least two microphone audio signals; determine spatial metadata transmit and/or store the spatial metadata and at least one of: at least one of the at least two microphone audio signals, at least one microphone audio signal from at least one second microphone configured to capture at least part of a same sound scene captured with the at least one first microphone, or at least one signal based, at least partially, on the at least two microphone audio signals, wherein the transmitting and/or storing is configured to enable synthesis of a plurality of spherical harmonic audio signals.

Features are disclosed for improving the accuracy and stability of beamformed signal selection. The selection may consider processing feedback information to identify when the current beam selection may need to be re-evaluated. The feedback information may further be used to select a beamformed signal for processing. For example, beams which detect wake-words or yield high confidence speech recognition may be favored over beams which fail to detect or recognize at a lower confidence level.
