Abstract

The invention relates to the technical field of voice coils, in particular to a high-efficiency combination structure of two reverse voice coils. The high-efficiency combination structure of two reverse voice coils includes a flexible circuit board, an upper ring voice coil, and a lower ring voice coil. The upper ring voice coil and the lower ring voice coil are respectively bonded on the upper and lower sides of the flexible circuit board. The ring includes a first long lead-out line and a first short lead-out line oppositely arranged, and the lower annular voice coil includes a second long lead-out line and a second short lead-out line oppositely arranged, and the flexible circuit board is provided with external terminals, Four outlet avoidances, four solder joints, and four copper-clad wires. The present invention cleverly uses the combination of double voice coils and flexible circuit boards, and uses two identical voice coils to be bonded and welded on the flexible circuit board to solve the problem of serial connection of voice coil wire ends and the external connection of voice coil lead wires , At the same time, it also avoids the problem that the traditional enameled wire lead-out wire is easily involved when it is drawn out, which plays a very good role in guaranteeing the performance of the product.

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 ...
