Abstract

The invention provides an optimal structure able to reduce sound leakage and improve transmission characteristics and control a vibration transmitting path of internal and external portions in a living organism conductive actuator. Therefore, the living organism conductive actuator has a communication signal transmitting portion for transmitting a communication signal in contact with an operator's wrist, hand, hand rear portion, finger, or nail tip, and a voice input portion.

Claims (12)

1. A living organism conductive actuator comprising:

a communication signal transmitting portion for transmitting a communication signal by vibration via one of a wrist, hand, hand rear portion, finger, and nail tip of a user, when the communication signal transmitting portion is in contact with said one of the wrist, hand, hand rear portion, finger, and nail tip of the user;

a voice input portion provided laterally adjacent to the communication signal transmitting portion; and

two wires having a spring property and mounted on an external portion to support the living organism conductive actuator.

2. The living organism conductive actuator according to claim 1 , further comprising a vibration-proof material on a living organism contact portion of the living organism conductive actuator, except for the communication signal transmitting portion.

3. A living organism conductive actuator comprising:

a communication signal transmitting portion for transmitting a communication signal by vibration via one of a wrist, hand, hand rear portion, finger, and nail tip of a user, when the communication signal transmitting portion is in contact with said one of the wrist, hand, hand rear portion, finger, and nail tip of the user;

a voice input portion provided laterally adjacent to the communication signal transmitting portion; and

a vibration-proof material on a living organism contact portion of the living organism conductive actuator, except for the communication signal transmitting portion.

4. The living organism conductive actuator according to claim 3 , further comprising:

an external portion;

two wires having a spring property and mounted on the external portion to support the living organism conductive actuator.
