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.

The present invention provides an earcap and an earplug, the earcap has a shell made of a flexible material, the two ends of the shell are respectively provided with a sound inlet and a sound outlet, the interior of the shell is disposed in a through manner, a filter net is disposed at a position close to the sound outlet, in the shell. The earplug comprises an earcap and a filtering core mounted in the earcap, the earcap has a shell made of a flexible material, two ends of the shell are open, the two ends of the shell are respectively provided with a sound inlet and a sound outlet, the interior of the shell is disposed in a through manner, the filtering core is mounted between the sound inlet and the sound outlet, a filter net is disposed at a position close to the sound outlet, in the shell.

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 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.

Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic function, and a wearable computer with optimal weight distribution and stretchable arms.

Various techniques are provided to implement and use an earpiece having an attachment mount. In one example, an earpiece includes an arcuate rib having a lobe disposed on an upper end thereof and configured to engage with a crus of a helix and an antihelix of a user's ear. The earpiece also includes a mount extending from the arcuate rib and comprising a snap clip configured to engage and position an audio device in contact with the user's ear. Other implementations and related methods are also provided.

This disclosure describes techniques for detecting voice commands from a user of an ear-based device. The ear-based device may include an in-ear facing microphone to capture sound emitted in an ear of the user, and an exterior facing microphone to capture sound emitted in an exterior environment of the user. The in-ear microphone may generate an inner audio signal representing the sound emitted in the ear, and the exterior microphone may generate an outer audio signal representing sound from the exterior environment. The ear-based device may compute a ratio of a power of the inner audio signal to the outer audio signal and may compare this ratio to a threshold. If the ratio is larger than the threshold, the ear-based device may detect the voice of the user. Further, the ear-based device may set a value of the threshold based on a level of acoustic seal of the ear-based device.
