WIPO Patent Application WO/2020/259439
Kind Code:
A1
Abstract:
Disclosed is a loudspeaker, comprising a basket, a cone accommodated in the basket, a voice coil, a surround, a damper and a magnetic circuit system. A first end of the cone is connected to a first end of the voice coil; a first end of the surround is connected to a second end of the cone; a second end of the surround is connected to the basket; a first end of the damper is connected to the cone, wherein the horizontal distance between a connection point of the first end of the damper and the cone and an axial center is greater than the outer diameter of a U-yoke in the magnetic circuit system, and the outer diameter of the voice coil is smaller than the inner diameter of the U-yoke; and a second end of the damper is connected to a rigid device. Further provided is a corresponding electronic device. According to the embodiments of the present application, the horizontal distance between a connection point of a damper and a cone and an axial center is set to be greater than the outer diameter of a U-yoke, and the outer diameter of a voice coil is set to be smaller than the inner diameter of the U-yoke, such that it can be realized that the damper is not connected to the voice coil, and therefore, the height of the damper is excluded from the measurement of the total height of a loudspeaker during a vibration process, the total height of the loudspeaker is reduced, and the thinning development of loudspeakers is achieved.
