Title:
LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2017/051843
Kind Code:
A1
Abstract:
The present invention eliminates constraints on the assembly procedure in a linear vibration motor, minimizes the occurrence of production defects such as coil breakage, and thereby improves workability at the time of assembly in a linear vibration motor that is suitable for reducing thickness. A linear vibration motor 1 is provided with: a movable element 2 provided with a magnet 2A and a weight 2B; a housing 3 for accommodating the movable element 2; a pair of coils 4A, 4B for applying driving force that causes the movable element 2 to vibrate to the magnet 2A; and an elastic member 5 for applying elastic force that repels the driving force to the movable element 2, said elastic member 5 being provided within the housing 3. The housing 3 is provided with a pair of support surfaces 3A, 3B along the direction of vibration of the movable element 2. The pair of coils 4A, 4B are fixed to each of the pair of support surfaces 3A, 3B and have the magnet 2A therebetween.
