Provided is an information processing device including an authentication unit configured to authenticate a user on the basis of collected sensor information, and the authentication unit authenticates the user on the basis of a single feature quantity extracted on the basis of sensor information collected by at least two sensors and a single registered feature quantity extracted on the basis of sensor information collected in advance by the at least two sensors.

An instrument configured to test the middle-ear function of a test subject, such as in tympanometry and impedance audiometry is provided. The instrument comprises an ear probe for insertion in an ear of test subject, the ear probe comprises an acoustic output unit comprising a receiver, the acoustic output unit being configured to provide a stimulus into the ear of the test subject via said receiver, an acoustic input unit comprising a microphone, the acoustic input unit being configured to receive a reflected part of said stimulus via said microphone and provide an electrical input signal, an ear-probe body for accommodating said microphone and said receiver, and an ear-probe tip comprising a tip opening for outputting said stimulus and receiving said reflected part of the stimulus, wherein the ear-probe tip comprises a sound tube with a longitudinal axis (A), where said sound tube provides access between a receiver opening and a microphone opening, respectively, and said tip opening, which receiver opening and microphone opening are arranged at a distance (L) from said tip opening along said longitudinal axis (A), and wherein the instrument is configured to provide said stimulus comprising one or more frequencies above 226 Hz into the ear of the test subject via said receiver.

The present disclosure discloses an acoustic output apparatus including at least one acoustic driver, a controller, and a supporting structure. The at least one acoustic driver may be configured to output sounds through at least two sound guiding holes. The at least two sound guiding holes may include a first sound guiding hole and a second sound guiding hole. The controller may be configured to control a phase and an amplitude of the sounds generated by the at least one acoustic driver using a control signal such that the sounds output by the at least one acoustic driver through the first and second sound guiding holes have opposite phases. The supporting structure may be provided with a baffle and configured to support the at least one acoustic driver such that the first and second sound guiding holes are located on both sides of the baffle.

A sensor on an earpiece is used to attempt to detect a signal corresponding to a heartbeat. If a heartbeat is detected, it can be determined that the earpiece is being worn by a user. The sensor may be an acoustic transducer on a surface of the earpiece that is located within the wearer's ear canal, while the earpiece is being worn normally.

A wearable audio output device with a rotatable input mechanism outputs first audio that is based on first media and, while outputting the first audio, receives a first input via the rotatable input mechanism. In response to receiving the first input: in accordance with a determination that the first input is a first type of input to the rotatable input mechanism that includes rotation of the rotatable input mechanism, the wearable audio output device changes an audio output volume of the first audio based on the rotation of the rotatable input mechanism while continuing to output the first audio; and, in accordance with a determination that the first input is a second type of input to the rotatable input mechanism, where the second type of input is different from the first type of input, the wearable audio output device ceases to output the first audio.

An ear-worn device includes: a microphone that obtains a sound and outputs a sound signal of the sound obtained; a DSP that performs signal processing on the sound signal to determine whether speech contained in the sound has reverberance, and outputs, based on a result of the determination, a first sound signal obtained by performing first signal processing on the sound signal; a loudspeaker that reproduces the sound based on the first sound signal output; and a housing that contains the microphone, the DSP, and the loudspeaker.

In an embodiment a wireless earphone includes an earbud portion having a speaker module, a stalk portion having a battery, wherein the earbud portion is connected to one end of the stalk portion, a circuit board and a first antenna being a slot antenna, wherein the circuit board extends from the earbud portion to an end of the stalk portion away from the earbud portion, wherein the circuit board is connected to the speaker module and the battery, wherein the circuit board comprises a reference ground, the reference ground extending from one end of the circuit board to another end of the circuit board, and wherein a slot is disposed on the reference ground forming a radiator of the slot antenna, the slot being located in the stalk portion and extending along a length direction of the stalk portion.

[Problem] To evaluate, easily and at low cost, the performance of an earphone device used for ear acoustic certification.

[Solution] Holes are provided in a plurality of plate-shaped members (201), an artificial eardrum member (202) corresponds to the eardrum of an individual, and the holes provided in each of the plurality of plate-shaped members (201) are connected, whereby the plurality of plate-shaped members (201) are layered over the artificial eardrum member (202) so as to simulate the external auditory canal of the individual.

The disclosure relates to a hearing device comprising a receiver module for insertion into an ear canal of a user of the hearing device, the receiver module comprising a signal processor, an output transducer, and a vent having a valve device, the valve device comprising at least one stationary valve coil, a movable magnet, and a movable valve element, the valve element being configured to open and close the vent, wherein the signal processor is configured to determine a current position of the valve element in the vent, and wherein the signal processor is configured to apply a drive signal to the valve coil to thereby move the valve element from the current position to a desired position. The disclosure further relates to a method for controlling a valve device of a hearing device and a binaural system.

An electronic device is disclosed. The electronic device according to the present disclosure includes a body, a neck formed at one side of the body, and a head formed on the neck, wherein the head comprises: a circular part connected to the neck; a protrusion part protruding from one side of the circular part and having a curvature that is greater than a curvature of the circular part; a speaker hole formed at at least one of the circular part and the protrusion part; and a band part formed at the periphery of the speaker hole, and the thickness of the band part may be greater than the thickness of the circular part or the protrusion part around the band part.
