## CPC

- H02K 33/16: with polarised armatures moving in alternate directions by reversal or energisation of a single coil system
- H02K: DYNAMO-ELECTRIC MACHINES (dynamo-electric relays H01H53/00; conversion of DC or AC input power into surge output power {H03K3/53})

## Abstract

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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

The vibrator of claim 1, wherein the elastic member is formed as a plate spring.

### Claim 5 (depends on 4)

The vibrator of claim 4, 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.

### Claim 6 (depends on 1)

The vibrator of claim 1, wherein the coil has a cylindrical shape so as to have the magnet disposed therein.

### Claim 7 (depends on 1)

The vibrator of claim 1, 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.

### Claim 8 (depends on 2)

The vibrator of claim 2, wherein the protective member is formed of a film made of a non-magnetic synthetic resin material.

### Claim 9 (depends on 1)

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.

### Claim 10

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.
