## Abstract

There is provided a vibrator, including: a case having an inner space; a vibration generating part mounted in the case and generating vibrations by power supplied thereto; and a resonance part resonated by the vibrations generated in the vibration generating part.

## Claims

### Claim 1

A vibrator, comprising:
a case having an inner space;
a vibration generating part mounted in the case and generating vibrations by power supplied thereto; and
a resonance part resonated by the vibrations generated in the vibration generating part.

### Claim 2 (depends on 1)

The vibrator of claim 1, wherein the case has a first space part having the vibration generating part mounted therein, and a second space part connected to the first space part and having the resonance part mounted therein.

### Claim 3 (depends on 1)

The vibrator of claim 1, wherein the vibration generating part includes:
a magnet fixedly mounted in a central portion of the first space part;
a first elastic member having a through hole through which the magnet penetrates and having an edge fixedly mounted in the case;
a coil fixedly mounted on the first elastic member so as to be disposed around the through hole;
a first mounting member fixedly mounted on the first elastic member so as to be disposed outwardly of the coil in a radial direction; and
a first weight member fixedly mounted on the first mounting member.

### Claim 4 (depends on 3)

The vibrator of claim 3, wherein the vibration generating part further includes a circuit board drawn out to the outside of the case and connected to the coil.

### Claim 5 (depends on 3)

The vibrator of claim 3, wherein the elastic member includes:
a mounting part fixedly mounted in the case;
an elastic part extending from the mounting part and being elastically stretched; and
a support part extending from the elastic part and having the through hole.

### Claim 6 (depends on 1)

The vibrator of claim 1, wherein the resonance part includes:
a second elastic member having an edge fixedly mounted in the case so as to be disposed in the second space part;
a second mounting member fixedly mounted on a top portion of the second elastic member; and
a second weight member fixedly mounted on the second mounting member.

### Claim 7 (depends on 1)

The vibrator of claim 1, wherein the vibration generating part includes:
a first elastic member having an edge fixedly mounted in the case so as to be disposed in the first space part;
a first mounting member fixedly mounted on a top surface of the first elastic member;
a magnet fixedly mounted in a central portion of the first mounting member;
a first weight member fixedly mounted on an outer peripheral surface of the first mounting member; and
a coil fixedly mounted in the case so as to face the magnet.

### Claim 8 (depends on 7)

The vibrator of claim 7, wherein the resonance part includes:
a second elastic member having an edge fixedly mounted in the case so as to be disposed in the second space part;
a second mounting member fixedly mounted on a top surface of the second elastic member; and
a second weight member fixedly mounted on an outer peripheral surface of the second mounting member.

### Claim 9 (depends on 7)

The vibrator of claim 7, wherein the vibration generating part further includes a yoke mounted on a top surface of the magnet.

### Claim 10 (depends on 7)

The vibrator of claim 7, wherein the vibration generating part further includes a buffer member mounted in the case so as to be disposed within the coil.
