A communication device for a hearing protection system comprising one or more hearing protection devices. The communication device comprises a processing unit, a memory, and an interface. The interface comprises a first hearing protection device interface comprising a first connector for connection of a hearing protection device. The interface comprises a second hearing protection device interface comprising a second connector for connection of a hearing protection device. The first connector and the second connector are of the same connector type.

The invention relates to a headset comprising at least one headband and at least one earpiece, the headband comprising a headband structure, wherein the headband structure is divided in at least one soft, flexible section and at least one stiff, non-flexible section, at least one sliding spring element, at least one handle element attached to the at least one sliding spring element and at least one guiding element, guiding the relative movement between the headband structure and the at least one sliding spring element.

This application relates to earbuds configured with one or more biometric sensors. At least one of the biometric sensors is configured to be pressed up against a portion of the tragus for making biometric measurements. In some embodiments, the housing of the earbud can be symmetric so that the earbud can be worn interchangeably in either a left or a right ear of a user. In such an embodiment, the earbud can include a sensor and circuitry configured to determine and alter operation of the earbud in accordance to which ear the earbud is determined to be sitting in.

The present disclosure relates to a speaker device. The speaker device may include a speaker assembly and a supporting connector. The speaker assembly may include a speaker module and a button module. The supporting connector may be configured to contact with the human head and provide a vibration fulcrum for a vibration of the speaker assembly. A distance between a center of the button module and the vibration fulcrum may be not greater than a distance between a center of the speaker module and the vibration fulcrum.

A handsfree device, which is coupled to a data processing device, may be operable to monitor at least one audio stream for occurrence of at least one keyword. Upon recognition of the at least one keyword, the handsfree device may establish a first connection between the handsfree device and the data processing device for launching a voice interface in the data processing device. The handsfree device may send audio data received after the recognition of the at least one keyword to the data processing device, via the first connection for responding to the audio data via the voice interface. During a keyword configuration operation, the handsfree device may send at least one inputted keyword to the data processing device for recording. The handsfree device may receive, via a second connection, the recorded at least one keyword from the data processing device for keyword configuration of the handsfree device.

A method for in-ear detection, the method may include transmitting test signals, by a speaker of an earbud, during a test period, and while the earbud is operating at a first operational mode, wherein the test signals comprise at least one first test signal within a first frequency range, at least one second test signal within a second frequency range, and at one third test signal within a third frequency range; wherein the first frequency range, the second frequency range and the third frequency range differ from each other and are within a human auditory range; generating, by a feedback microphone of the earbud, sensed information that is indicative of audio signals sensed by the feedback microphone as a result of the transmitting of the test signals; and determining whether the earbud is located within an ear of a person, wherein the determining is based on the sensed information and a reference out of ear spectrum.

Provided are a wireless earphone and a method for controlling a wireless earphone. The wireless earphone includes a charging box and an earpiece placed in the charging box. A charging box open/closed-state sensor, an earpiece attitude sensor and a magnetic-field control circuit are disposed in the charging box. The charging box open/close-state sensor is configured to detect an open state of the charging box or a closed state of the charging box. The earpiece attitude sensor is configured to detect an orientation attitude of the earpiece in the charging box. The magnetic-field control circuit controls, according to results detected by the charging box open/closed-state sensor and the earpiece attitude sensor, whether the earpiece is suspended from the charging box.

Retention members for an in-ear headphone include a base portion and a substantially straight flexible finger extending from the base portion. Absent external forces, the flexible finger includes a substantially straight longitudinal axis and a back surface extending from a proximal end portion to a distal end portion and having a plurality of recesses along a length of the back surface. The flexible finger is configured to, during use, bend into a curved shape for disposition under a user's antihelix. In-ear headphones include a shell defining a volume housing an audio driver, a nozzle extending from the shell configured for at least partial insertion into an ear canal, and a flexible retention member coupled to the shell, the flexible finger including a substantially straight longitudinal axis, a back surface, and a concave front surface.

The present disclosure generally relates to user interfaces for electronic audio devices. In some examples, the operating mode of the device changes to various states of sound transparency.

A method and apparatus for adapting an electronic device to receive digital television broadcast signals is disclosed. The device comprises a switch commandable to interpose one or more matching networks as in the RF signal path according to a channel command to match an integrated headset antenna to the tuner receiving the RF signals.
