PURPOSE:To produce sound by vibrating a vibration bar of an electric device by receiving the power to actuate an IC into which the sounds are incorporated from said electric device. CONSTITUTION:Power supply input terminals 1 and 2 are connected to a handset terminal in a telephone set, and the pulsating voltage generated when a handset is hooked off is rectified by a bridge D and a capacitor C1 to be used as a power supply of the telephone main body. The sounds incorporated into an IC vibrate the vibration bar of the telephone receiver and are sent to a subscriber at the remote side through a transmitter microphone. When the handset is picked up to set a call state, the functions are weakened for both the line of magnetic force of a coil in the telephone and the handset. Thus the transmission is discontinued for the incorporated sounds. As a result, the telephone talking is possible with a melody to obtain a happy and pleasant utmosphere. |
