Document Type and Number:
WIPO Patent Application WO/2023/082745
Kind Code:
A1
Abstract:
The present invention relates to the technical field of voiceprint recognition and voice call devices, and in particular to a voiceprint recognition and voice call noise-cancelling device, comprising a shell, a first elastic conduction piece, an elastic pressing piece, and a bone conduction microphone. A mounting cavity is formed in the shell, a mounting hole is further formed on the shell, and the mounting hole is communicated with the mounting cavity. The first elastic conduction piece is arranged in the mounting hole and seals the mounting hole. The elastic pressing piece is fixedly arranged in the mounting cavity and correspondingly arranged behind the first elastic conduction piece. The front end of the bone conduction microphone is fixed onto the first elastic conduction piece, the rear end of the bone conduction microphone is fixed onto the elastic pressing piece, the front and rear ends of the bone conduction microphone are suspended in the mounting cavity respectively by means of the first elastic conduction piece and the elastic pressing piece and are elastically connected to the shell, and the force of the elastic pressing piece acting on the bone conduction microphone is directed to the first elastic conduction piece, so that the bone conduction microphone is tightly attached to a wearing position by means of the first elastic conduction piece and is suitable for wearers of various head shapes.
