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.

摘要： A linear moving coil magnetic drive system includes a continuous loop coil of flat, thin, rigid construction which levitates inside a quadrupole permanent magnet assembly with minimum gap. The linear coil may be a flat, racetrack-shaped, continuous loop, which may be constructed with single or multilayers PCB, flex-circuit, or other membrane process. The linear coil may include a coating of permeable magnetic material along the insulated conductor traces. The linear coil may be sandwiched between carbon fiber fabrics and cured to create a long, flat, thin and perfectly straight, extremely stiff, light-weight, load-bearing tee-shaped structure. This structure is levitated inside a quadrupole permanent magnetic assembly with minimum air gap between the high gauss magnets. In additional to the bare conductor traces inside this coil, also integrated into this PCB structure, is simple second-order equalizer electronic circuitry, comprised of surface-mounted resistors, capacitors, and IC chips. Either a close loop or open loop control may be included to tune the voltage amplitude at the resonance frequency of this magnetic drive system.

摘要： The present invention relates to a flat-type speaker, and more particularly, to a flat-type speaker having one magnet for transferring vibration into a diaphragm and two voice coil plates in one magnetic circuit, wherein the voice coil plates are coupled to both sides of the magnet. The flat-type speaker in which n magnets and n+1 voice coil plates are coupled to each other consists essentially of: the magnet positioned on a central portion; a pair of yoke plates having magnetic bodies spaced a predetermined distance apart from the magnet, such that the magnet is between the yoke plates; two voice coil plates having voice coils inserted between the magnet and one of the yoke plates and between the magnet and the other yoke plate; and a diaphragm vibrated by receiving the vibration of the voice coil plates in a state where the diaphragm contacts upper ends of the voice coil plates.
