    摘要： Acoustic transducer comprises an upper part (301) and a lower part (302), with a first permanent magnet (303) in the upper part (301) and a second permanent magnet (304) in the lower part (302). Similarly named magnetic poles of the first and second permanent magnets (303, 304) face each other. An upper cover (306) in the upper part (301) and a lower cover (307) in the lower part (302) comprise magnetic material and define an enclosure around the magnets (303, 304). A coil (308) creates, under influence of an electric current, dynamic magnetic forces. A separating gap (309) between edges of said upper cover (306) and lower cover (307) is directed so that it allows a relative movement of the edges of said lower cover (307) and said upper cover (306) between different positions, said positions differing in the extent to which edges coincide.

    摘要： Disclosed is a sound producing device, including a magnetic circuit system and a vibration system. The magnetic circuit system includes a primary magnet steel and a secondary magnet steel with a magnetic gap therebetween, wherein the secondary magnet steel includes a body portion and a protruding portion protruding in a direction toward the primary magnet steel from the body portion, and wherein the primary magnet steel has a primary magnetic conductive plate disposed thereon. The vibration system includes a diaphragm and an voice coil wound by wire, wherein the voice coil is inserted in the magnetic gap to drive the diaphragm to vibrate, and wherein a number of layers of wire winding at an end of the voice coil away from the diaphragm are less than that of layers of wire winding at another end of the voice coil contacting with the diaphragm, to form a notch.

    摘要： A multifunctional sound device includes a housing, a sound unit, and a motor assembly. The sound unit includes a frame, a vibration system, a magnetic circuit system, and a first elastic component. The vibration system includes a vibrating diaphragm and a a voice coil. The voice coil drives the vibrating diaphragm to vibrate and generate sound along a first direction. A first end of the first elastic component is fixed to the frame. A second end of the first elastic component is elastically connected to the magnetic circuit system. The voice coil drives the magnetic circuit system to vibrate along the first direction. A mounting groove is defined on the magnetic circuit system. The motor assembly includes a stator and second elastic components. The stator is fixed to the housing. The stator is spaced apart from the magnetic circuit system and drives the magnetic circuit system to vibrate.
