## Abstract

A call selective receiver body includes a built-in rechargeable small battery and a small vibrator, and a belt clip for receiving the receiver body includes a built-in dry battery having an electric capacity significantly greater than that of the small battery in the receiver body and a relatively large built-in vibrator. When the receiver body is put into the belt clip, a vibrator control signal output terminal of the receiver body is connected with a vibrator control signal input terminal of the belt clip, and electric power input terminals of the receiving body are connected with electric power output terminals of the belt clip, whereby the electric power source for the receiver is switched from the smaller battery in the receiver body to the greater battery in the belt clip; the rechargeable small battery in the receiver body starts being recharged; and the vibrator in the belt clip is made in action.

## Claims

### Claim 1

A call selective receiver, comprising:
a receiver body;
a first power source housed in the receiver body and having a first electric capacity;
a first vibrator also housed in the receiver body and having a first vibration amplitude;
a belt clip having a cavity therein configured to receive the receiver body;
a second power source housed in the belt clip and having a second electric capacity greater than the first electric capacity;
a second vibrator also housed in the belt clip and having a second vibration amplitude greater than the first vibration amplitude, whereby a vibration can be transmitted to a user through the belt clip; and
a power source switching means for switching from the first power source in the receiver body to the second power source in the belt clip when the receiver body is inserted into the belt clip.

### Claim 2 (depends on 1)

A call selective receiver as claimed in claim 1, wherein the power source switching means comprises a pair of input terminals and a pair of output terminals, the pairs being connected with or disconnected from each other when the receiver body is inserted into or removed from the belt clip, respectively.

### Claim 3 (depends on 1)

A call selective receiver as claimed in claim 1, wherein the first power source in the receiver body is rechargeable, and can be recharged from the second power source when the receiver body is inserted into the belt clip.

### Claim 4 (depends on 1)

A call selective receiver as claimed in claim 1, wherein the second power source is a dry battery.

### Claim 5 (depends on 1)

A call selective receiver as claimed in claim 1, further comprising a control signal transmitting means disposed between the receiver body and the belt clip, for transmitting a control signal for switching from the first vibrator in the receiver body to the second vibrator in the belt clip when the receiver body is inserted into the belt clip.

### Claim 6

A method of driving a vibrator of a call selective receiver, comprising:
providing a receiver body housing a first power source and a first vibrator;
providing a belt clip housing a second power source and a second vibrator, and having a cavity configured for receiving the receiving body; and
transmitting a call signal to a user's body through the belt clip when the receiver body is inserted into the belt clip by driving the second vibrator when a call signal is received.
