Abstract

The invention relates to the technical field of voice coils, in particular to an efficient combined structure of two reverse voice coils. The efficient combined structure of the two reverse voice coils comprises a flexible circuit board, an upper annular voice coil and a lower annular voice coil, the upper annular voice coil and the lower annular voice coil are bonded to the upper face and the lower face of the flexible circuit board respectively, and the upper annular voice coil comprises a first long outgoing line and a first short outgoing line which are oppositely arranged. The lower annular voice coil comprises a second long outgoing line and a second short outgoing line which are oppositely arranged. The flexible circuit board is provided with an external connection end, four outgoing line receding openings, four welding spots and four copper-clad wires. According to the invention, the combination of the double voice coils and the flexible circuit board is ingeniously applied, the two same voice coils are bonded and welded on the flexible circuit board to ingeniously solve the problems that the voice coil wire ends are connected in series and the voice coil leading-out wire is led out to be an external connection end, and the problem that the traditional enameled wire leading-out wire is easy to be dragged when being led out is also avoided; and the performance of the product is well guaranteed.

Description

technical field [0001] The invention relates to the technical field of voice coils, in particular to a high-efficiency combination structure of two reverse voice coils. Background technique [0002] In the field of communication technology, a microphone is a device responsible for converting the voice and sound signals emitted by the speaker into electrical signals for output. Microphones are generally divided into two categories: air conduction microphones and contact microphones. The air-conduction microphone is an instrument that directly converts the received voice signal transmitted by air vibration into an electrical signal output; the contact microphone is close to the head or neck of the human body, and picks up the skull or throat when the person makes a sound. An instrument that generates slight vibrations and converts them into electrical signals for output. Moreover, the existing contact microphones usually adopt a single voice coil structure, and the magnetic ...
