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.
1. A vibrator, comprising:
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,
wherein the weight body has a disc shape and includes a mounting part formed on an outer peripheral surface thereof, the mounting part having the magnet mounted thereon, and
wherein a bottom surface and an inner peripheral surface of the magnet are bonded to the mounting part.
2. The vibrator of claim 1 , further comprising a protective member fixedly mounted on an inner surface of the coil to prevent the coil from being damaged.
3. The vibrator of claim 2 , wherein the protective member is formed of a film made of a non-magnetic synthetic resin material.
4. The vibrator of claim 1 , further comprising a circuit board drawn out to an outside of the case from an inside thereof and connected to the coil.
5. The vibrator of claim 1 , wherein the elastic member is formed as a plate spring.
6. The vibrator of claim 5 , wherein the elastic member includes a weight body bonding part to which the weight body is bonded, an elastic deformation part extending from the weight body bonding part, and a fixing part extending from the elastic deformation part so as to be fixedly mounted on the case.
7. The vibrator of claim 1 , wherein the coil has a cylindrical shape so as to have the magnet disposed therein.
8. The vibrator of claim 1 , further comprising a damping member mounted on the case so as to face the weight body to reduce an impact generated when the weight body contacts the case.
9. A vibrator, comprising:
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;
a magnet fixedly mounted on the weight body so as to face the coil;
a protective member fixedly mounted on an inner surface of the coil to prevent the coil from being damaged;
a circuit board mounted on a top surface of the coil and having one end drawn out to an outside of the case; and
a damping member mounted on the case so as to face the weight body to reduce an impact generated when the weight body contacts the case,
wherein the weight body has a disc shape and includes a mounting part formed on an outer peripheral surface thereof, the mounting part having the magnet mounted thereon, and
wherein a bottom surface and an inner peripheral surface of the magnet are bonded to the mounting part.
