specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings: as shown in Figure 1, the voice single-chip IC of the utility model adopts the EST model. The power supply voltage of the circuit is 4.5V, and the core part of the circuit is to use the voice microcontroller EST chip, where the IC pins VDD and VCC are the positive poles of the power supply; the IC pins VSSD and VSSC are the negative poles of the power supply; the IC pin OSC1 is connected to an external oscillation resistor Rosc＝100K; IC pin RESET is the reset pin, when the external capacitor C1 works, keep enough time when starting up to make the IC reset reliably. The IC pins P10-P13 are the input ports of the IC. Among them, P10 is the input port of the candle switch. When the candle is inserted, the switch S2 is turned on, P10 changes from low level to high level, and the input terminal is triggered; P11 is the voice control input port. When we use our mouth to blow out the candle , the voice control signal received by MICROPHONE2 is coupled to the triode Q4 through C2 for primary amplification, and then the signal is sent to Q5 for secondary amplification, and the signal is input to P11 port; P12 is used as the control port of voice control input. When the key ENABLE is pressed , the voice control input will take effect.

P21 is the output port of the candle lamp. When P21 outputs a high level, the current is limited by the resistor R3, and then amplified by the triode Q2 to drive the candle lamp (light-emitting diode D1); P22 is the voice-activated amplifier circuit to control the power output. When the IC is in the standby state , P22 is turned off to save power consumption.

P32 is the infrared output terminal. The infrared intermediate frequency signal is limited by R5, and then amplified by the triode Q3, which drives the red emission tube D2 to emit infrared signals. VO is the audio output, and R8 is the lower bias resistor, which is amplified by the transistor Q6 to drive the speaker LS1 to sound.

Among them, the IC pins VDD and VCC are the positive pole of the power supply; the IC pins VSSD and VSSC are the power supply for the negative pole of the power supply; the IC pin OSC1 is connected with an external oscillation resistor Rosc=100K; the IC pin RESET It is the reset pin, and when the external capacitor C1 acts, it will keep enough time when it is turned on so that the IC can be reset reliably.

The IC pins P10-P13 are the input ports of the IC. P10 is the hand press input port, when the hand press switch S1 is pressed, P10 changes from low level to high level, and the IC enters the normal state; P11 is the program selection pin, when the power is turned on, this pin is low level and enters ON program, enter the TRYME program if the level is high; P13 is the infrared signal receiving input pin, (see the right side of the circuit diagram) IC output port P20 charges the electrolytic capacitor C1 through the resistor R5, provides power for the infrared receiving head, and the infrared receiving head receives The signal is transmitted to the IC via R6 to the internal decoding through the external line input pin P13 to judge whether the received signal is correct? What action to take based on the received signal.
