Hands-free electronic devices and electronic functions that can be worn on the surface of the body in a biologically fit manner are described. The embodiments provide a convergence between electronic products, and biological, anatomical, and biomechanical aspects of the human body while providing hands-free and interchangeable wearable electronic apparatuses that can interact with human senses and physiology of a human body in a practical manner.

An audio system for a headset includes a plurality of speakers and an audio controller. The plurality of speakers may be in a dipole configuration that cancel sound leakage into a local area of the headset. The controller filters audio content presented by the plurality of speakers to further mitigate leakage of audio content into the local area. The audio determines sound filters based on environmental conditions, such as ambient noise levels, as well as based on the audio content being presented.

A noise cancelling headset includes first and second earpieces, each earpiece including a respective feedback microphone, a respective feed-forward microphone, and a respective output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

A wireless earphone system (1) comprising a first earphone (2) and a second earphone (3). The first earphone (2) comprises a first earphone transceiver (6) of a first type and a second earphone transceiver (7) of a second type, and the second earphone (3) comprises a third earphone transceiver (7) of the first type. A first wireless link (5) can be established between the first earphone transceiver (6) and the third earphone transceiver (8), and a second wireless link (9) can be established between the second earphone transceiver (7) and an audio rendering transceiver (25) of the second type of an audio rendering device (4). The first earphone device (2) is adapted to send a link status signal (12) via the second wireless link (9) to the audio rendering device (4).

An earphone including a speaker that outputs sounds to a uniaxial direction; a sound guide tube offset from a center of the speaker to and disposed on one side of a direction orthogonal to the uniaxial direction, the sound guide tube extending to a direction parallel to the uniaxial direction; and a housing accommodating the speaker and supporting a base end of the sound guide tube, wherein the housing is broadened from the base end to other side opposite to the one side, toward a location where the speaker is accommodated, and has an inclined surface that inclines at the broadened location, and a separation distance between a central axis of the speaker and a central axis of the sound guide tube is smaller than an internal radius of the sound guide tube.

Conformable vented eartips are provided. A comfortable vented eartip includes an ear insertion end, an earphone insertion end opposite the ear insertion end, a base at the ear insertion end extending toward the earphone extension end, a central opening extending through the base to form an inner sound channel through the base, and at least one flange. The at least one flange includes a first flange end extending from the base at an angle away from the base and toward the earphone insertion end at a second flange end. The at least one flange includes at least one swept indent extending between the first flange end and the second flange end. The at least one swept indent sweeps laterally around a portion of a circumference of the at least one flange.

In an audio system, an audio signal is preprocessed to provide an input signal to a fast detector and a slow detector, the input signal comprising alert signals and ambient sounds. The slow detector determines the ambient sound level of the input signal which is output to an alert signal detector. The alert signal detector uses the ambient sound level to compute an adaptive threshold level using an adaptive threshold function. The fast detector determines the envelope level of the input signal which is output to the alert signal detector. The alert signal detector compares the envelope level to the adaptive threshold level to determine if an alert signal is present in the input signal. The adaptive threshold level varies depending on the ambient sound level of the input signal and the alert signal detection of the audio system automatically adapts to changing acoustic environments having different ambient sound levels.

An audio assembly provides audio content to a user. The audio assembly comprises an elongated body, a diaphragm, a transducer, and a plurality of vent assemblies. The elongated body has a first end and a second end opposite the first end. The diaphragm is within the elongated body and pivots about a pivot location that is proximate the second end. The transducer is within the elongated body and is positioned proximate to the first end. The transducer causes the diaphragm to pivot about the pivot location such that the diaphragm generates a positive acoustic pressure wave from a first surface of the diaphragm and a negative acoustic pressure wave from a second surface of the diaphragm. The plurality of vent assemblies are along one or more surfaces of the elongated body, and are configured to vent the positive acoustic pressure wave and the negative acoustic pressure wave.
