A linear vibration motor includes a stator part including a case having an internal space formed in the case, a bracket coupled to the case to close the internal space, and at least a magnet provided in the internal space, a vibrator part provided in the internal space, including a coil positioned so as to face the magnet and a printed circuit board having one end coupled to the bracket and the other end coupled to the coil, and an elastic member connecting the stator part and the vibrator part to each other.

Linear vibration motor with protrusion blocking solder attaching printed circuit board to case

There are provided a vibrator and an electronic device including the same, the vibrator including a housing having an internal space; a shaft included in the internal space; a vibrating part suspended in the internal space by elastic members at both ends thereof, including a magnetic field part, and having a bearing member slidably and movably installed on the shaft; and a coil generating vibrations of the vibrating part through electromagnetic interaction with the magnetic field part and provided on an outer peripheral surface of the shaft while facing the magnetic field part.

Vibrator and electronic device including the same

A linear vibration device may comprise a stator assembly including a plate and a case, and a vibrator assembly including a yoke and a spring. The case of the stator assembly and the spring of the vibrator assembly may be coupled to each other. The case may be provided with a protrusion, the spring may be provided with a groove, and the protrusion and the groove may be coupled to each other.

Linear vibration device having spring

There is provided a linear vibrator including a case including a cylindrical sidewall part forming a sidewall thereof and a cover coupled to one end of the sidewall part, and an elastic member including at least one connection protrusion and connected to the case while the connection protrusion is interposed between the sidewall part and the cover.

Linear vibrator and method of manufacturing the same

There is provided a vibration generating device, including: a housing including an inner space; a shaft provided in the inner space of the housing in an axial direction; a frame including a shaft hole into which the shaft is fitted; a bearing member mounted on the frame to be vibrated in a state of contact with the shaft; a vibrating part mounted on an outer surface of the frame and including a magnetic field generation part; elastic members mounted on both ends of the vibrating part in the axial direction; and a coil provided in the inner space and vibrating the vibrating part by interaction with the magnetic field generation part.

Vibration generating device

There is provided a vibrator, including: a case having an inner space; a coil fixedly mounted on a side wall of the case; an elastic member fixedly mounted on the case so as to be disposed within the coil; a weight body fixedly mounted on the elastic member; and a magnet fixedly mounted on the weight body so as to face the coil.
