Title:
LINEAR VIBRATION MOTOR, AND PORTABLE ELECTRONIC DEVICE PROVIDED WITH SAID LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/018443
Kind Code:
A1
Abstract:
The purposes of the present invention are: to enable compactness and a reduction in thickness to be achieved; to facilitate work related to the installation of a plurality of coils; and to improve vibration resistance and impact resistance of the plurality of coils. The present invention is provided with: a movable element 10 provided with a magnet part 4 and weights 7; a frame body 2 which accommodates the movable element 10 so as to enable reciprocal movement thereof along a uniaxial direction; coils 3A, 3B which are wound around the periphery of the magnet part 4 along a direction intersecting the uniaxial direction, and which exert driving force on the magnet part 4 in the uniaxial direction; and elastic members 6 which exert, on the movable element 10, elastic force which repels the driving force. The plurality of coils 3A, 3B are provided along the uniaxial direction, are integrated so as to respectively be in contact with the other neighbouring coil, and are fixed to the frame body 2.
