## Abstract

An integrally-designed bone conduction driver relates to the technical field of headsets using bond conduction speaker technologies, and overcomes technical disadvantages of existing bone conduction speakers, namely, complex processes and poor comfortability when they are worn. The bone conduction driver includes a vibrating plate, a voice coil, an elastic piece, a magnet, a washer, and a cup holder, where a wire outlet end of the voice coil is fixed on an inner side face of the vibrating plate; the vibrating plate is connected to the cup holder by using the elastic piece as an elastic support; the elastic piece includes an inner ring part, at least two outer arc parts that are concentric with and in clearance fit with the inner ring part, and at least two connection parts connecting tail ends of the outer arc parts to the inner ring part; and the voice coil is integrally combined with the inner side face of the vibrating plate. Meanwhile, an additional elastic piece and an additional support that support each other and that fix the voice coil are not needed between the vibrating plate and the cup holder, so that the process is simple and easy, there are fewer parts, and the combination is simple. Not only the weight is reduced, but also the sensitivity and the kinetic energy are increased, and the shape is special and aesthetic.

## Claims

### Claim 1

An integrally-designed bone conduction driver, comprising:
a vibrating plate, a voice coil, an elastic piece, a magnet, a washer, and a cup holder,
wherein the voice coil comprises a tubular framework and a coil and a lead wire that are coiled on the framework;
a wire outlet end of the voice coil is fixed on an inner side face of the vibrating plate;
the vibrating plate is connected to the cup holder by using the elastic piece as an elastic support;
the elastic piece comprises an inner ring part, at least two outer arc parts that are concentric with and in clearance fit with the inner ring part, and at least two connection parts connecting tail ends of the outer arc parts to the inner ring part;
front ends of the outer arc parts and the inner ring part are respectively connected to the vibrating plate and the cup holder;
the magnet is fixed at an internal central position of the cup holder, the washer is fixed on the magnet in a gluing manner, the washer is coaxial with the magnet, and the washer is disposed in an inner cavity of the voice coil and in uniform clearance fit with the voice coil;
the vibrating plate comprises a plate body having a diameter the same as that of the brim of the cup holder, a side of the plate body being provided with at least two fixed feet that are each fixedly connected to the front end of each outer arc part; and
the inner ring part is attached to and fixedly connected to the brim of the cup holder, and the cup holder is a component of a magnetic circuit.
