摘要： 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.
