Abstract: A head-mounted adjustment device includes a housing, a connecting rod, a first magnetic member, and a second magnetic member, and a strap. The housing includes an adjusting cavity and an adjusting opening. The connecting rod movably installed in the adjusting cavity moves in the direction close to or away from the adjusting opening. The first magnetic member installed at an end of the connecting rod moves synchronously with the connecting rod. The second magnetic member is located on one side of the first magnetic member close to the adjusting opening; parts of the first magnetic member and the second magnetic member facing each other are isotropic magnetic poles of each other. The strap having one end connected to the connecting rod, and another end extends out of the adjusting opening to expand and contract in a direction close to or away from the adjusting opening.

Abstract: Embodiments of the present disclosure provide a harmony processing method and apparatus, a device, and a medium, and the method includes: acquiring a harmonic interval corresponding to a target harmony control in response to a triggering operation on the target harmony control; performing, according to the harmonic interval, sound modification processing on a first sound input originally to obtain a second sound, in which an interval between the first sound and the second sound is the harmonic interval; and generating a target audio according to the first sound and the second sound, wherein the first sound and the second sound are presented as different harmonic parts in the target audio.

Abstract: The present disclosure provides an audio processing method and apparatus, a device, and a storage medium. The method includes: in response to a first instruction, displaying a first control on a first interface, where the first control is associated with audio editing; in response to an operation on the first control on the first interface, displaying one or more third controls, where the one or more third controls are configured to trigger corresponding audio editing on audio; and in response to an operation on a third control of the one or more third controls, triggering audio editing corresponding to the third control on audio to be processed, to acquire target audio.

Abstract: The present disclosure provides an audio processing method and apparatus, a device, and a storage medium. The method includes: acquiring, in response to an audio acquisition instruction, to-be-processed audio; performing, in response to an audio extraction instruction for the to-be-processed audio, audio extraction on the to-be-processed audio, to obtain target audio, where the target audio is a vocal and/or an accompaniment extracted from the to-be-processed audio; and presenting the target audio.

Abstract: A tunneling system includes a bolter miner, a bolter-integrated transportation machine, a transfer machine, a self-moving tail and a belt conveyor. The bolter miner includes a rack, a cutting device, and a bolt support device. The bolt support device includes a lifting assembly, a work platform, a first drilling frame assembly and a stabilizing assembly. The lifting assembly is arranged between the rack and the work platform. The first drilling frame assembly and the stabilizing assembly are arranged on the work platform. The bolter-integrated transportation machine is arranged behind the bolter miner and configured to transfer coal rock cut and conveyed by the bolter miner. One end of the transfer machine is connected with the bolter-integrated transportation machine, and the other end of the transfer machine is lapped with the self-moving tail. The belt conveyor is arranged behind the self-moving tail.
