Abstract:
An instrument-playing portable communication device is provided. The device includes an instrument-playing key unit having one or more keys, provided on a body of the instrument-playing portable communication device. When a user selects a chord of a selected instrument by pressing at least one of the one or more keys, the instrument-playing key unit converts the at least one key press into a first signal. The device also includes a sensor unit mounted in the body, for sensing a motion of a user. When the user presses the at least one of the one or more keys and moves in a location near the sensor unit, the sensor unit senses a motion of the user and converts the motion into a second signal. The device further includes a controller for receiving the first signal from the instrument-playing key unit and the second signal from the sensor unit, generating a tone frequency of the selected instrument based on the received signals, and converting the tone frequency into a tone. The device additionally includes an amplifier for amplifying the tone output from the controller, and outputting the amplified tone through a speaker mounted in the body.
