The utility model discloses an intelligence biological teaching aid and toy. Two sensors which are mutually connected are respectively connected with a conditional reflex function circuit. A trigger pulse dispensing circuit and an electric level transfer circuit are respectively connected with the conditional reflex function circuit, a speech generator circuit and a music generator circuit. A power amplifier is respectively connected with the speech generator circuit, the music generator circuit, a loudspeaker and an indicator. The utility model has the advantages of more functions, vitality, fun, and simple circuit structure. The utility model is a fan toy for developing the intelligence of people, and is a teaching aid with practical valve.
Description
The utility model is about teaching aid and toy, and more particularly, the utility model is about having the intelligence biological teaching aid of conditioned reflex function.
Selling various voice-control toys in the market, they are made of audio-switch, music generator circuit or speech synthesizer circuit, power amplifier, loudspeaker and indicator etc.When people sent sound, music generator circuit or speech synthesizer circuit in the toy were just sounded.The weak point of this toy is a function singleness, lacks interesting and intelligent.
The purpose of this utility model is to overcome shortcoming of the prior art, and a kind of intelligent biological teaching aid with conditioned reflex function is provided, and is again a kind of toy simultaneously.
The utility model is achieved by following technical proposals.
Interconnected two sensors connect the conditioned reflex functional circuit respectively, trigger pulse distributes and level shifting circuit connects conditioned reflex functional circuit, speech synthesizer circuit and music generator circuit respectively, and power amplifier connects speech synthesizer circuit, music generator circuit and loudspeaker respectively.Described conditioned reflex functional circuit is made of comparer, memory cell, threshold circuit, monostalbe trigger and release channel; Described comparer connects threshold circuit, monostalbe trigger respectively, and release channel connects memory cell, threshold circuit, monostalbe trigger respectively.
Described power amplifier also can connect indicator.A kind of in described sensor employing sound, light, magnetic, the human body sensor.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a schematic block circuit diagram of the present utility model;
Fig. 2 is the circuit diagram of conditioned reflex functional circuit.
Sensor J1 and J2 can select photoelectric tube, tongue tube, Electret condenser microphone head, human body sensing sheet etc. as required for use.Sensor J1 places the mouth of toy animals, and sensor J2 places head of animal or other position.The sensor of present embodiment adopts tongue tube.Interconnected sensor J1 and J2 connect respectively to have and judge relatively and the IC1:B and the memory cell C1 of release function that IC1:B meets the IC1:A with threshold circuit and monostalbe trigger function.IC1:B works in the comparer state in the described conditioned reflex functional circuit, and IC1:A works in the monostable state, and IC1:A and IC1:B are made of integrated circuit 556 in the present embodiment.Circuit each several part annexation is as follows: the end of tongue tube J1 and J2 links to each other with an end of resistance R 2 and receives ' 8 ' and ' 12 ' pin of IC1:B more jointly; The R2 other end links to each other with ' 13 ' pin of IC1:B; ' 4 ' of ' 10 ' pin of one end of resistance R 1 and the end of R9, IC1:B and IC1:A links to each other with ' 14 ', receives positive supply VCC jointly; The other end of resistance R 1 links to each other with the other end of J1; The positive pole of C1 links to each other with the other end of J2, ' 7 ' the pin common ground of the negative pole of C1 and the negative pole of C2 and IC1:A; The other end of R9 links to each other with the positive pole of C2, is connected to ' 1 ' and ' 2 ' pin of IC1: A more jointly.' 9 ' pin of IC1:B connects ' 6 ' pin of IC1:A; ' 5 ' pin of IC1:A outputs to trigger pulse and distributes and level shifting circuit 4.
Described trigger pulse distributes and level shifting circuit 4 is made of the transistor emitter follower.Speech synthesizer circuit 5 can adopt KD-1562 series integrated circuit chip.Music generator circuit 6 can adopt KD-5600 series integrated circuit chip.Power amplifier 7 can adopt transistor amplifier.Loudspeaker 8 can adopt dynamic loudspeaker.Indicator 9 can adopt light emitting diode or neon tube etc.
Principle of work of the present utility model is described below.
When energized, the equal no signal output of sensor J1 and J2, trigger pulse distributes and level shifting circuit 4 sends signal, make speech synthesizer circuit 5 sound, with regard to the doggie teaching aid, just send the cry of " tearful ... ", if rag baby can send laugh or sob etc.
Sensor J1 externally condition (for example magnet) acts on down, produce a signal level, when this level surpasses the comparative threshold voltage of comparer, the output of comparer is just overturn, thereby triggering monostalbe trigger, distribute and level shifting circuit 4 by its control trigger pulse, make 6 work of music generator circuit.
When sensor J1 is subjected to the external condition effect, sensor J2 is subjected to the effect of another external condition, bar magnet for example, the signal level that sensor J1 produces makes the output switching activity of comparer on the one hand, provides memory signal by sensor J2 to memory cell C1 on the other hand.When memory cell C1 through repeatedly the memory, stored signal surpasses after the threshold level, if only sensor J2 is applied external condition, level signal among the memory cell C1 just can be delivered to comparer, make its output switching activity, initiating trigger distribution and level shifting circuit 4, music generator circuit 5, meanwhile, comparer discharges a part to the energy among the memory cell C1 by release channel.After repeating several times, the level among the memory cell C1 just is lower than turn threshold, thus the conditioned reflex disabler.
The utility model compared with prior art has following advantages:
1. function of the present utility model is many, but circuit structure is simple, not only be easy to make, and also with low cost.
2. vivid and interesting, the intelligence that can inspire people.
3. not only can be used as toy, can also be as the usefulness of biology Class teaching aid.
Claims (3)
1. intelligence biological teaching aid and toy, comprise speech synthesizer circuit, power amplifier, loudspeaker, it is characterized in that, interconnected two sensors connect the conditioned reflex functional circuit respectively, trigger pulse distributes and level shifting circuit connects conditioned reflex functional circuit, speech synthesizer circuit and music generator circuit respectively, and power amplifier connects speech synthesizer circuit, music generator circuit and loudspeaker respectively; Described conditioned reflex functional circuit is made of comparer, memory cell, threshold circuit, monostalbe trigger and release channel; Described comparer connects threshold circuit, monostalbe trigger respectively, and release channel connects memory cell, threshold circuit, monostalbe trigger respectively.
