The image control data transmitting means 190, as shown in the Fig. 3, comprises a FM modulator 191, a first amplifier 192 and a second amplifier 193. The FM modulator 191 generates a FM modulating signal while a crystal XTAL oscillates according to a time constant of oscillation predetermined by a variable capacitance diode VD, condenser C2 and coil LI , where the variable capacitance diode VD varies in its capacitance according to the the image control data outputted from the system controller 110. The first amplifier 192 serves to amplify the output signal of the FM modulator 191 with a transistor Ql . The second amplifier 193 serves to amplify the output signal of the first amplifier 192 with transistors Q2 and Q3 to thereafter transmit it through the antenna 180. With the microphone for automatic accompaniment thus constructed, if a user selects a desired song by manipulating the key input means 120 provided within the microphone prior to singing a song, the system controller 110 is activated to determine the desired accompaniment melody to display it through the display means 130, and also to output the desired accompaniment melody through the accompaniment melody store means 141 and at the same time output the image control data according to the accompaniment melody to the image control transmitting means 190.

The mixing means 149 serves to mix the accompaniment melody outputted from the amplifier 145 with the song sound signal outputted from the echo means 148. The sound signal mixed by the mixing means 149 is outputted via the switch 160, and converted into a FM signal by the transmitting means 170 to thereafter be transmitted wirelessly via the antenna 180. During such operations, the mixed sound (voice) signal of the accompaniment melody outputted from the mixing means 149 is converted into a digital signal by the analogue-to-digital converter 151 of the record and playback means 150 and inputted into the memory unit 152,. The memory unit 152 successively stores the digital signals outputted from the analogue-to-digital converter 151 in response to address signals outputted from the system controller 110. And, the image control data according to the the accompaniment outputted from the system controller 110 is inputted into the FM modulator 191 and the capacitance of the variable capacitance diode VD varies in response to the image control data, thereby the oscillation time constant predetermined by the variable capacitance diode VD, condenser C2 and coil LI varies. As a result, the FM-modulated signal is generated while the oscillation frequency of the crystal XTAL varies in response to the image control data, the FM modulation signal of the image control data generated by the FM modulator 191 is amplified through the transistor Ql and is again amplified through the transistors Q2, Q3 in the second amplifier 193 to thereafter to betransmitted through the antenna 180. When the user finishes singing a song and selects playback function by manipulating the key input means 120, the system controller 110 controls the switch 160 so that the moving terminal is electrically connected to the other fixing terminal (bl), and at the same time controls the memory unit 152 of the record and playback means 150 so that the stored signal is outputted in order. The signal outputted from the memory unit 152 is converted into the analogue signal by the digital-to-analogue converter 153 to thereafter be outputted through the switch 160 and is converted into the FM signal by the transmitting means 170 to thereafter be transmitted through the antenna 180.
