A remote controller for a sound delivery system such as hearing aids and headsets is shown and described. The remote controller has control buttons corresponding to control functions of the sound delivery system, a signal generator, a signal transmitter, and a power supply. The sound delivery system is worn on the head or ears, and includes speakers, sounding controlling elements, a signal receiver for communication with the remote controller, a power supply, and audible and/or visible beacons for implementing a locator function if misplaced or lost. The remote controller may be a stand alone, dedicated component physically separate from the sound delivery system, or alternatively, may be implemented as an application downloadable to a cellular telephone. The application causes manual controls corresponding to those of a hearing aid or stereophonic controls to appear on a screen of the cellular telephone.

A headphone, headphone system, and speech enhancing method is provided to enhance speech pick-up from the user of a headphone and includes receiving a plurality of signals from a set of microphones and generating a primary signal by array processing the microphone signals to steer a beam toward the user's mouth. A noise reference signal is also derived from one or more microphones via a delay-and-sum technique, and a voice estimate signal is generated by filtering the primary signal to remove components that are correlated to the noise reference signal.

Disclosed are techniques to improve power consumption of portable audio devices through the use of a plurality of adapters. Each of the plurality of adapters can be used to modify and/or enhance the functionality of the portable audio device. The portable audio device can include respective circuitry that is activated in response to detecting that a specific one of the plurality of adapters is coupled to the portable audio device.

The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

Aspects relate to systems and methods for dynamic active noise reduction including at least a sensor configured to sense a physiological characteristic of a user and transmit a physiological signal correlated to the sensed physiological characteristic, at least an environmental microphone configured to transduce an environmental noise to an environmental noise signal, a processor configured to receive the environmental noise signal, generate a noise-reducing sound signal as a function of the environmental noise signal, and, modify the noise-reducing sound signal as a function of the physiological signal, and a speaker configured to transduce a noise-reducing sound from the modified noise-reducing sound signal.

A wireless audio streaming system for swimmers and underwater applications uses directional transmission antennas, one or more reception antennas worn on a user, and a combination of radio frequency and near-field magnetic induction communication, for streaming audio to a swimmer, buffering the streamed audio, and allowing the user to play the audio on a wireless, waterproof headset.

Devices and methods for controlling the functionality of a pair of earbuds. The first earbud establishes a connection between the first earbud and an electronic device, searches for the second earbud of the pair of earbuds using Body Coupled Communication, BCC, and sends a signal from the first earbud to the electronic device including information defining whether the first earbud detected the second earbud during the search. The electronic device receives a signal from the at least one of the earbuds, the signal comprising information defining whether the earbud has detected the other earbud of the pair of earbuds using Body Coupled Communication, BCC, and sends a signal to the at least one earbud wherein the signal is controlled based on the received signal and includes information associated with controlling the functionality of the pair of earbuds.

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.

The present disclosure provides a HIFI system based on digital connection, which includes an audio outputting device and a HIFI module, the audio outputting device is detachably connected with the HIFI module, when the audio outputting device is connected with the HIFI module, the audio outputting device is electrically connected with the HIFI module, the HIFI module includes a digital analog conversion circuit and a digital interface electrically connected with the digital analog conversion circuit, the digital interface transmits a received digital signal from external to the digital analog conversion circuit to be converted to an analog signal. The present disclosure only need to connect the HIFI module connected with the audio outputting device with the sound source device, and overcomes the problem that user cannot listen to the sound source due to the losing or forgetting to carry the digital analog converter.

A headset includes a wearable body, first and second earphones extending from the wearable body, controls for controlling an external communication/multimedia device wirelessly, a microphone for picking up vocal data from a user of the headset system and a signal processing unit. The signal processing unit includes circuitry for processing the vocal data into a distinctly audible vocal feedback signal, circuitry for enhancing the vocal feedback signal thereby producing an enhanced vocal feedback signal and circuitry for mixing the enhanced vocal feedback signal with audio signals originating from the external communication/multimedia device, thereby producing a mixed output signal and then sending the mixed output signal to the user via the earphones. The external communication/multimedia device comprises a vocal command application and the headset further comprises a vocal command control for sending vocal commands to the external communication/multimedia device and to the vocal command application.
