Microphone array calibration method and apparatus, a telephone headset, a storage medium and a computer program product are provided. The method includes: when detecting that a position at which a microphone boom is located is deflected relative to pre-configured reference position, determining target distance between each microphone in a microphone array and a mouth, the microphone array being configured to collect a sound from the mouth and installed in the microphone boom; in a case where the microphone boom is located at the reference position, obtaining reference distance between each microphone and the mouth and reference value for calibration parameter used for calibrating each microphone; determining target value for calibration parameter corresponding to each microphone based on a difference between the target distance and the reference distance and the reference value; and calibrating the microphone array based on target value for calibration parameter corresponding to each microphone.

Disclosed are a method and a device for calibrating a microphone array of a headset, and a headset. The headset includes a headset body and a microphone array arranged on the headset body. The microphone array includes a plurality of microphones. The method includes: obtaining a preset reference distance of each microphone; detecting a current body direction of the headset body, and determining a distance between each microphone and the sound source to obtain a target distance of each microphone corresponding to a determination that a detected current body direction of the headset body is deflected relative to the preset body direction; obtaining a preset acoustic parameter reference value of each microphone; comparing the target distance of each microphone with the preset reference distance of a corresponding microphone, and updating the preset acoustic parameter reference value of each microphone; and calibrating the microphone array.

An earphone adapted for being worn on an ear is provided. The earphone includes an acoustical component and a wearing component. The wearing component is connected to the acoustical component, and the acoustical component and the wearing component together form an acoustic chamber. The wearing component includes a positioning portion, a sound output surface and an acoustic sound outlet. The acoustic sound outlet is located on the sound output surface and connected to the acoustic chamber. When the earphone is worn on the ear, the positioning portion extends into the ear and abuts against a cavum conchae of the ear, and the sound output surface faces an ear canal of the ear.

An earphone adapted to be worn on an ear is provided. The earphone includes a wearing component and an acoustical component. The wearing component includes a front positioning structure and an acoustic channel, and the acoustic channel is located in the front positioning structure. The acoustical component is connected to the wearing component, and the acoustical component includes an acoustic chamber, and the acoustic chamber is connected to the acoustic channel. When the earphone is worn on the ear, the wearing component is located in a cavum conchae of the ear, a surface of the earphone adjacent to a bottom of the concha cavity is located on a datum plane, and the acoustical component and the front positioning structure are located on a first side of the datum plane. The bottom of the concha cavity is located on a second side of the base plane.

An earphone adapted to be worn on an ear is provided. The earphone includes a wearing component and an acoustical component. The wearing component includes a front positioning portion and an acoustic channel. The front positioning portion is located on an extension axis of the wearing component. The acoustical component is connected to the wearing component, and the acoustical component includes an acoustic chamber, and the acoustic chamber is communicated with the acoustic channel. When the earphone is worn on the ear, the front positioning portion is covered by a tragus of the ear and exerts a first positioning force on the tragus, so that the wearing component is positioned in a cavum conchae of the ear. The acoustic channel corresponds to an ear canal of the ear.

An earphone adapted to be worn on an ear is provided. The earphone includes a wearing component and an acoustical component. The wearing component includes a rear positioning portion and an acoustic channel. The acoustical component is connected to the wearing component, and the acoustical component includes an acoustic chamber, and the acoustic chamber is connected to the acoustic channel. When the earphone is worn on the ear, the wearing component is located in a cavum conchae of the ear, and the rear positioning portion exerts a positioning force on a rear edge of the cavum conchae, so that the earphone is positioned in the ear. The acoustic channel corresponds to an ear canal of the ear.

A wireless headphone including a housing, an ear part, and a hidden cover is provided. The housing has a receiving space for mounting a battery. The ear part is disposed at a side of the housing. The hidden cover is disposed at the housing and adjacent to the ear part, and the hidden cover has a base and a covering member. The base is connected to the housing, and the ear part is sleeved at a side of the base. The covering member is movably disposed at the base and adjacent to the ear part. In an open mode, the covering member is adapted to slide along the base away from the housing and expose the battery. In a closed mode, the covering member is adapted to slide along the base to be in contact with the ear part and the housing and shield the battery.

An electronic device includes a first structure, a second structure and a fixing assembly. The fixing assembly is disposed on the first structure and includes a first cam, a second cam and an adjustment element. The first end of the adjustment element is exposed to the outside of a first housing, and the second end of the adjustment element passes through the first cam and the second cam. When the first structure is connected to the second structure, a first engaging part of the second structure engages with a second engaging part of the second cam to assume a first state. The adjustment element rotates and drives the first cam to rotate relative to the second cam, thereby pushing the second cam away from the first cam to release an engaging relationship between the second engaging part and the first engaging part, and assume the second state.

Gain management method and device for telephone headset, a telephone headset and a medium are provided. The method includes: detecting a wear state of a headset body of the telephone headset, the headset body being connected to a microphone boom of the telephone headset, a microphone module being provided in the microphone boom; when the wear state of the headset body is a worn state, detecting a first distance from the microphone boom to the head of a human wearing the headset body; when the first distance is within the range of a pre-configured standard distance, maintaining an input gain of the microphone module at a standard gain value; and when the first distance is beyond the standard distance range, adjusting the input gain to a first gain value which is greater than the standard gain value.
