Abstract

A telephone handset 1 in which a melody circuit board 2 is housed. This melody circuit generates a signal so that a melodic sound can be transmitted to a receiver of the other side while holding the line a moment. The circuit board is housed in the interior of the telephone handset and connected to the line of the transmitter through a capacitor 4. A switch is connected to the melody circuit board for switching it from the power supply of the telephone set. <IMAGE>

Description

SPECIFICATION Telephone handset having a melody circuit board FIELD OF THE INVENTION This invention relates to a telephone handset having a melody circuit board housed therein, particularly to a telephone handset having the melody circuit board which generates a melody signal so that a melodic sound can be transmitted to a receiver of the other side while holding the line a moment.
DESCRIPTION OF THE PRIOR ART In prior art, a separate melodic sound generating apparatus is provided for transmitting the melodic sound to the other side while holding the line a moment. This separate apparatus for generating the melodic sound and transmitting it to the receiver of the other side is troublesome and inconvenient in use.
And not only this separate apparatus is expensive, but because of its complicated structure, it frequently gets out of order. Further, it is difficult to maintain this separate melodic sound generating apparatus in a confined place or on a desk.
SUMMARY OF THE INVENTION An object of the invention is to provide a telephone handset in which a melody circuit board is housed.
According to the invention, the melody circuit board housed in the telephone handset generates a melodic sound signal and transfers it to a receiver of the other side while holding the line a moment.
BRIEF DESCRIPTION OF THE DRA WINGS Figure 1 is a perspective view of a telephone handset having a melody circuit board in accordance with the invention; and Figure 2 is a circuit diagram.
DESCRIPTION OF THE PREFERRED EMBODI MENTS In Fig. 1, it shows a telephone handset 1 comprising a transmitter 6A and a receiver 6B. The telephone handset 1 is connected to a telephone set, not shown, by a wire 5. In the interior of the telephone handset 1, a melody circuit board 2 which generates a melodic signal is housed, and a switch 3 is connected to the melody circuit board 2. The slide button of the switch 3 is project on the back of the telephone handset 1. The melody circuit board 2 housed in the interior of telephone handset 1 is fed to the line of the transmitter 6A through a capacitor 4.
While holding the line a moment, one can push the button of the switch 3 on one side so that the power supply of telephone set may be connected to the melody circuit board 2. Then the melody circuit board 2 generates a melodic signal, which is amplified in the amplifier of telephone set, and this audio melody sound is transmitted to the receiver of the other side.
Again, when one wants to communicate with the other side, he would release the button of the switch 3 to the "off" position, then the melody circuit is switched off from the power supply of telephone set, and one can continue to communicate with the other side.
The melody circuit 2 may be a integrated circuit in which several musical melodies are stored, and can be played repeatedly.
As explained above, the telephone handset of this invention is very simple and convenient. And, because it is possible to massproduce, this invention can be marketed at a low price.
1. A telephone handset, having a melody circuit board housed in the interior of the telephone handset and connected to the line of the transmitter through a capacitor, and a switch connected to the melody circuit board for switching it from the power supply of telephone set.
2. A telephone handset substantially as hereinbefore described with reference to, and as illustrated in, the accompanying drawing.
