Document Type and Number:
WIPO Patent Application WO/2016/194762
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase drive force to a limit without affecting the vibration stroke in a linear vibration motor that has a plate spring disposed between a weight and a frame. A linear vibration motor 1 is provided with a frame 2, a weight 3, and a plate spring 4, and is also provided with weight side drive members 5 disposed within a through hole 3B in the weight 3 and attached with the through hole space along the direction of vibration therebetween, and a frame side drive member 6 supported by the frame 2 and disposed so as to pass through the through hole space. The plate spring 4 has a frame side seating part 4A attached to the frame 2, a weight side seating part 4B attached to an end surface 3A of the weight 3, and an elastic deformation part 4C that elastically deforms between the frame side seating part 4A and the weight side seating part 4B. The weight side drive members 5 are disposed so as to protrude from the end surface 3A of the weight 3 in the range of the thickness of the plate spring 4.
