  • The operational principles of the electromotive toy processor with voice synchronisation according to the present invention are as follows. It is divided into an audio circuit, a voice electromotive synchronisation circuit and automatic shutting-down circuit to be explained as below respectively.
  • (1) As for the audio circuit, the voice from the voice source is passed to the 4th pin of the voice power amplifying IC block IC1 via the stereo plug X1 through the impedance matching network (capacitor C3, resistors R1, R2), wherein the voice is power amplified, one path of the voice is negatively feedback to the 4th pin through the resistor R2, allowing the quality of the voice played to be improved, and the other path of the voice directly drives the speaker BL1 to utter audio voice via two terminals of the IC1, i.e. the 8th and 5th pins. The voice from the portable microphone is passed through the amplifier comprised of the MIC socket, V4 and peripheral elements, wherein it is amplifier to be passed to the 4th pin of the IC block IC1, allowing the IC block to drive the speaker BL1 to utter the voice so as to accompany a singer.
  • (2) As for the voice electromotive synchronisation circuit, a voice is output from the 5th pin of the IC block IC1 and passed through the band-pass filter (capacitor C5, capacitor C17 and resistor R21) to select an audio signal ranging from 200 Hz to 4 KHz. The audio signal is passed through the resistors R4, R5, capacitor C17 and transistor V1 to perform processes on the amplitude and intervals of the signal, so as to select a valid signal to be converted to pulse, and the pulse signal is then passed through capacitors C6, C7, diodes D1, D2 to perform a voltage multiplication to allow it have certain driving power. The transistor V2, V3 and resistor R6 form a combined tube for power driving, in that the resistor R6 acts as a role for current restriction protection.
  • The rotation of the electromotor drives the shift gear (43) by the link motion strap wheel (2), the shift gear (43) drives the gear (44) by a gear engagement, the gear (44) drives the gear (45) by engagement, and then the link rod (46) and the swing handle (47) are engaged by the cam of the gear (45), the lower lip member (49) engages and operates by the link rod (46), and the link rod (46) and the upper lip member (48) are integrated into one. Therefore, it forms an up-down action between the upper lip and the lower lip. Since it forms an up-down action by the link rod (6), the lower lip would swing up and down by the link rod (6). The action of the mouth of the pet toy configured like this would act in synchronisation with the amplitude of the voice from the voice source. The swing of the pet would be performed by the swing handle.
  • (3) As for the automatic shutting-down circuit, when a signal is input to the plug of the voice source, the signal is passed through the capacitor C14 and the resistor R11 to be amplified by the transistor V5. During the negative half period of the signal, due to the feedback of V8, V5 is turn off, V9 is turn off, V10 is turned on in saturation, allowing the capacitor C16 to be charged with a voltage, and V6 and V7 to be turned on in saturation, so as to make the audio circuit and the voice electromotive synchronisation circuit to be powered on and operate normally. When no voice source signal is input to the plug of the voice source, due to the bias of the resistor R12 of the base electrode of the transistor V5, V5 is turned on in saturation, V9 is turned on in saturation, and V10 is turned off. The voltage on the capacitor C16 is discharged via R14, V6 would be turned off and V7 would be turned off after an approximate 30 s or so, and the audio circuit and the voice electromotive synchronisation circuit would be shut down automatically.
