PURPOSE:To make a melody stored in a card listen to an opposite party in holding a talking by using the card storing the melody preferred by a possessor. CONSTITUTION:In operating a holding button 7 to hold the talking state, a control circuit 8 activates a switching relay 5 to switch a transmission and reception circuit. On the other hand, in loading the card 9 to a read circuit 10, the read circuit 10 reads the digital signal of the melody stored in the card and transfers it to a temporary storage circuit 11. A voice conversion circuit 12 extracts the information from the temporary storage circuit 11 and converts it into an analog signal (melody). An amplification circuit 13 amplifies the melody tone to a degree listened to for other party and sends the result. In making a talking with other party again, a holding button 7 is restored, a control circuit 8 restores a switching relay 5 to attain the talking.
