Abstract: 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.

Abstract: The present disclosure discloses a voice coil wire, a voice coil manufactured by winding the voice coil wire, a loudspeaker and a vibration motor, and relates to the technical field of electroacoustic products. The voice coil wire comprises a conductor layer having an electric conduction function, the outside of the conductor layer being wrapped by an insulating layer, wherein the conductor layer comprises a first conductor layer disposed inside and a second conductor layer wrapping the outside of the first conductor layer, and one of the first conductor layer and the second conductor layer is made of a soft magnetic material. The voice coil wire, the voice coil manufactured by winding the voice coil wire, the loudspeaker and the vibration motor of the present disclosure solve the technical problem of the prior art that voice coils do not have magnetoconductivity. The voice coil wire, the voice coil manufactured by winding the voice coil wire, and the voice coils in the loudspeaker and the vibration motor of the present disclosure have a magnetic conduction function, effectively improve the performances of the loudspeaker and the vibration motor and reduce the masses and sizes of the loudspeaker and the vibration motor.
