Abstract

A toy type children telephone set, which mainly comprises a full functional telephone printed circuit board (abbreviated TPCB thereafter). The TPCB is encased in a toy-shaped outer case, instead of a traditional ringing bell. The TPCB is provided with an IC sound generator circuit, which produces a crying, laughing, or singing sound correlating to the embodied toy shape of the outer case when this telephone set is rung. Moreover, in the audio circuit of this TPCB, it is provided with an audio signal conversion circuit, so that through a bridge inverter it controls the rotation of a permanent magnet motor, this motor in turn drives the upper and lower lips at the head portion of the toy-shaped outer case to open or close by following the audio sound signal fluctuation via a driven mechanism and leaf spring switches, which attracts the children to use this telephone set happily.

Claims

1. A telephone set including a telephone power supply for supplying power to said set, said set comprising:

an outer case in the shape of a children'"'"'s toy;

a dialing key board mounted on said outer case;

a hand-set mounted on said outer case, said hand-set including an earphone circuit and a microphone circuit, each of said circuits of said hand-set adapted to tap out signals;

a telephone printed circuit board disposed in a hollow internal space within said outer case and just above a base plate of said outer case;

a lip driving mechanism connected to lips disposed at a head portion of the outer case;

a leaf spring switch connected to said lip driving mechanism;

an IC sound generator circuit disposed on said telephone printed circuit board for producing a crying, laughing or singing sound correlated to the toy shape of the outer case when the telephone set is ringing;

an audio frequency amplifier connected to said hand-set for receiving said tapped out signals from said earphone circuit and said microphone circuit and generating amplified signals;

a converter circuit connected to said amplifier for receiving said amplified signals and generating converted signals;

a bridge inverter connected to said converter circuit for receiving said converted signals and generating control signals;

a permanent magnet motor connected to said bridge inverter for rotating in a direction controlled by said control signals for driving the lips provided at the head portion of the outer case to open or close by following audio signal fluctuations occurring in said tapped out signals of said earphone and microphone circuits when a telephone conversation is going on;

a self-contained battery pack separate from the telephone power supply for supplying power to said audio frequency amplifier, said converter circuit, said bridge inverter and said motor, said battery pack being separate from the telephone power supply and being adapted to use a common line therewith.

2. The telephone set as set forth in claim 1, further comprising an attenuator circuit connected to said microphone circuit for receiving said tapped out signals from said microphone circuit and generating attenuated signals, said attenuated signals being received by said amplifier.

3. The telephone set as set forth in claim 1, wherein said outer case is in the shape of a dog or a rabbit.
