Various aspects include audio amplifiers for driving at least one speaker. In some cases, the amplifier includes: a controller for amplifying at least one input signal to provide an amplified audio output signal, the controller configured to operate the amplifier in at least two modes, including: a first mode including a dedicated connection to the at least one speaker; and a second mode including a direct physical connection with an additional audio amplifier and the dedicated connection to the at least one speaker, where in the first mode and the second mode the amplifier is configured to provide the amplified audio output signal to drive the at least one speaker, and in the second mode the amplifier is configured to forward the at least one input signal to enable the additional audio amplifier to control audio output at an additional speaker.

A system for providing magnetic field audio signals to a receiver in an aquatic environment. The system includes an audio source configured to provide an electronic audio signal, and an induction loop amplifier configured to receive the electronic audio signal and convert the received electronic audio signal into a current. The system further includes a wire loop connected with the induction loop amplifier, the wire loop bounding at least part of the aquatic environment and around the receiver in the aquatic environment, the wire loop producing a magnetic field from the current to generate an audio frequency induction loop to transmit the electronic audio signal to the receiver in the aquatic environment.

A system and method for improving hearing enhancement solutions across a wide range of hearing devices, particularly for a wide-range of disparate user-provided hearing devices.

This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.

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.

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.

A method for providing sound to at least one user, in which audio signals are captured and transformed into audio data that is transmitted to at least one receiver unit; audio signals are generated from the received audio data and the hearing of the user(s) stimulated thereby; wherein the audio data is transmitted as audio data packets in separate slots of a TDMA frame structure, wherein the transmission unit and the receiver unit(s) are synchronized to form a wireless network, wherein each TDMA frame structure has at least one listening slot during which the synchronized network members do not transmit data and at least one network members listens, and wherein control data is transmitted from an external control device according to a sequence pattern selected according to the duration and periodicity of the listening slot(s) to be received by the at least one synchronized network member during said listening slot(s).

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.

This specification describes a method comprising determining whether an estimated position of an audio capture device which captures audio data is within boundaries of a predetermined area, and in response to a determination that the estimated position is not within the boundaries of the predetermined area, associating the captured audio data with an adjusted position.

A wireless noise-cancelling earplug includes a housing within which at least an active noise cancellation (ANC) circuit for producing anti-noise, a speaker for emitting the anti-noise as a sound wave, and a battery for powering at least the ANC circuit. The earplug further includes an audio cavity for guiding the sound wave from the speaker out of the earplug, at least one microphone for measuring ambient noise and feeding the measured ambient noise to the ANC circuit, and a passive noise reduction unit for blocking ambient noise.
