    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： The present invention provides a double-vibrating-diaphragm loudspeaker module. The double-vibrating-diaphragm loudspeaker module comprises: a peripheral housing providing with a first sound outlet hole and a second sound outlet hole; a supporting structure fixed on an inner wall of the peripheral housing; and a loudspeaker unit comprising a first vibrating diaphragm, a sound coil, a magnetic circuit system and a second vibrating diaphragm. The sound coil and the magnetic circuit system are separately combined with the first vibrating diaphragm and the second vibrating diaphragm. The sound coil is accommodated in a magnetic gap of the magnetic circuit system. Edges of the first vibrating diaphragm and the second vibrating diaphragm are fixed on the supporting structure. The peripheral housing, the supporting structure and the loudspeaker unit form a first front sound cavity, a second front sound cavity, and a rear sound cavity. The first front sound cavity comprises a space between the first vibrating diaphragm and a part closing to the first vibrating diaphragm, of the peripheral housing, and communicates with the external by using the first sound outlet hole. The second front sound cavity comprises a space between the second vibrating diaphragm and a part closing to the second vibrating diaphragm, of the peripheral housing, and communicates with the external by using the second sound outlet hole. The rear sound cavity comprises a space between the first vibrating diaphragm and the second vibrating diaphragm and forms a sealed hollow cavity. The double-vibrating-diaphragm loudspeaker group can improve high and low frequency acoustic features.

    摘要： Embodiments provide a microphone assembly such as a headphone or headset which comprises a mechanical acoustical low pass filter between the microphone and the speaker so as to effectively attenuate higher frequencies fed back to the microphone. The low pass filter may comprise a hole or tunnel which connects a front volume of the microphone with a front volume of the speaker, providing a reliable and effective stable structure. An attenuation material may be provided for adjusting the attenuation of the low pass filter.
