A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

An interactive control method and device of earphones, an earphone and a storage medium are disclosed. The earphones include a first earphone and a second earphone. The method comprises: acquiring putting-on sequential order information or taking-off sequential order information of the first earphone and/or the second earphone; determining a first functional instruction corresponding to the putting-on sequential order information or a second functional instruction corresponding to the taking-off sequential order information according to a preset correspondence between the putting-on sequential order information or the taking-off sequential order information and functional instructions of a mobile terminal; and sending the first functional instruction or the second functional instruction to the mobile terminal, so that the mobile terminal executes the first functional instruction or the second functional instruction to realize a first interaction function or a second interaction function with the earphones.

A device and a method for detecting voice of a user of an intra-aural device. The intra-aural device has an in-ear microphone adapted to be in fluid communication with an outer-ear ear canal of the user occluded from an environment outside the ear. A signal provided by the in-ear microphone is obtained to determine an acquired voice indicator signal, and a voice produced by the user is detecting by comparing the acquired voice indicator signal with a corresponding threshold value, upon the acquired voice indicator signal being larger than the corresponding threshold value. Although the method also reduces any voice interference coming from a non-user, the results are improved when the non-user voice is captured from an outer-ear microphone of the intra-aural device.

A mixed, virtual and augmented reality headset having a front casing (2) with a housing receiving a smartphone (19) facing the holographic display (5); a curved holographic display (5) in the front portion of the headset reflecting a projected image (11) via the display of a smartphone (19) and simultaneously allowing the user to see through same; a motorised mirror (14) positioned in a withdrawn position or in an extended position in front of the holographic display (5) reflecting the projected image (11) via the smartphone (19); two motorised lenses (15) positioned in a withdrawn position or in an extended position in front of the pupils (13) of the user; a mirror system (16) reflecting a real external image (10) with respect to the headset (1) towards a camera of the smartphone (19); and a control unit (50) controlling the position of the motorised lenses (15) and mirror (14).

The disclosure accurately authenticates a subject, regardless of which audio device is used for the in-ear acoustic authentication. A feature extraction unit (11) applies a test signal to an ear of a subject using an audio device, and upon receiving an acoustic signal from the subject, extracts, from the acoustic signal, a first feature relating to the system consisting of the audio device and the ear of the subject; a correction unit (12) corrects the first feature to a second feature that would result if a prescribed reference device were used instead of the audio device; and an authentication unit (13) authenticates the subject by comparing the second feature with a feature indicated by pre-registered authentication information.

A lawn vehicle network including a lawn vehicle including a movement mechanism and at least one rotatable blade, a circuit capable of residing on the lawn vehicle, a sensor associated with the lawn vehicle and capable of sensing at least one characteristic of the lawn vehicle, a data packet representative of the at least one characteristic of the lawn vehicle, a transmitter connected to the circuit and to a computing device, the transmitter capable of transmitting the data packet to the computing device, the computing device connected to a speaker, the speaker capable of outputting an audible command representing the at least one characteristic of the lawn vehicle.

A communication apparatus capable of easily switching communication between the communication apparatus and an external reproduction device. A communication section performs wireless communication with an earphone that is capable of automatically switching audio data transmitted from a plurality of communication apparatuses including the communication apparatus and reproducing the audio data. A state detection section detects whether or not the communication apparatus is used by a user. In a state in which the communication apparatus has not been used, when it is detected that the communication apparatus is used, the communication unit transmits a reproduction switching signal for switching the earphone to a state for reproducing audio data transmitted from the communication apparatus to the earphone before transmitting the audio data.

An earphone includes a main body and a stabilizer. The stabilizer is movably disposed on the main body and has a stored position and at least one sticking out position. When the stabilizer is in the stored position, the stabilizer covers part of a contour of the main body. When the stabilizer is in the at least one sticking out position, part of the stabilizer sticks out the main body and is spaced apart from the main body by a specific distance.

A processing device according to this embodiment includes: a frequency characteristics acquisition unit configured to acquire frequency characteristics of an input signal; an extreme value extraction unit configured to extract an extreme value of spectral data; a kurtosis calculation unit configured to: calculate an evaluation value from spectral data; and calculate a kurtosis of a peak or a dip based on a plurality of evaluation values calculated by changing a calculation width, the evaluation value being used for evaluating the peak or the dip corresponding to the extreme value; a determination unit configured to determine whether to suppress the peak or the dip according to a comparison result between the kurtosis and a threshold value; and a suppression unit configured to suppress the peak or the dip with the extreme value that is determined to be suppressed.

A voice sound reduction device having a sound dampening cup that conforms to a user's face around the user's mouth, a microphone on an interior of the sound dampening cup electronically paired to a communication device, and a means for positioning the sound dampening cup to a user's face.
