Abstract

A watch includes a sound input body and a main body. The main body include an interface unit, a first electromagnetic coil unit, a signal processing unit, and a control unit. The sound input body includes a microphone and a second electromagnetic coil unit. The second electromagnetic coil unit generates inducted electromagnetic filed in response to an electric signal generated by the microphone. The first electromagnetic coil unit coupling the second electromagnetic coil unit generates electric signal in response to the electromagnetic field. The signal processing unit filters algorithm of the electric signal. The control unit recognizes the electric signal amplified by the signal amplification unit to execute corresponding function.

Claims

1. A watch comprising:

a sound input body comprising;

a microphone configured to detect and receive sound and convert the sound into an electric signal; and

a second electromagnetic coil unit connected to the microphone, configured to generate an induced electromagnetic field in response to the electric signal generated by the microphone;

a main body comprising;

an interface unit;

a first electromagnetic coil unit coupled with the second electromagnetic coil unit, and configured to generate an electric signal in response to the generation of the electromagnetic field by the second electromagnetic coil unit;

a signal processing unit configured to filter noise in the electric signal generated by the first electromagnetic coil unit; and

a control unit connected to the signal amplification unit via the interface unit, configure to recognize the electric signal amplified by the signal amplification unit to execute corresponding function.

2. The watch as recited in claim 1, further comprising a strap configured to tied the main body to user'"'"'s wrist, and the sound input body is mounted on the strap.

3. The watch as recited in claim 2, wherein the sound input body is mounted on the main body.

4. The watch as recited in claim 1, wherein the second electromagnetic coil unit is mounted on a frame of the main body.
