Abstract

The utility model discloses a toy baby, comprising an A machine and a B machine. Both the A machine and the B machine comprise transmitting circuits and receiving circuits; the A machine is arranged in the belly of the toy of the utility model; the B machine is used for the remote control. The B machine is arranged in the distance to the baby of the utility model; the A machine in the belly of the baby of the utility model is remotely controlled by the B machine to sound; after the A machine is closed, the two-way switch of the A machine makes the baby of the utility model automatically have the function that the baby of the utility model sends out laughter via the control of the touching switch of a language circuit; the A machine in the belly of the baby of the utility model sends out the sound of a child via the B machine which is provided with a modulation circuit.

Description

Talking toy baby

The utility model relates to a kind of toy for children, is meant a kind of Talking toy baby especially.

Toy for children on the market is various in style, but the most action or sound that dullness is only arranged.Be accompanied by day by day increasing of only-child, children lack partner of the same age, easily form the lonely personality of behavior.Therefore, a kind of can the dialogue with the people, can tell a story, the doll of singing, children's best partner beyond doubt also will become simultaneously the head of a familys' good assistant.

The purpose of this utility model provides and a kind ofly can make toy send the Talking toy baby of Tong Yin by remote control.

Characteristics of the present utility model and advantage are: 1. utilize the wireless interspeaker principle, A machine receiver is placed doll's abdomen, loudspeaker can be positioned on doll's head, and the B machine can place in 50 meters of dolls, utilizes A machine sounding in the B machine remote control doll abdomen.2.A after office closed, the two-way switch of A machine had by the soft-touch control of language circuit the doll automatically and controls, and sent the function of laugh.3. make by the B machine that the A machine sends Tong Yin in doll's abdomen, people can talk by doll's mouth and children, recreation, children are educated or issue an order etc., can hear child's reply formula question by earphone because of the head of a family, thereby realize doll and child's dialogue function, make the cloth doll in child's hand become vividly affable.4.B machine is equipped with the modified tone circuit, and K1, K2, four selector switches of K3, K4 are arranged, and makes the A function send seven kinds of tones respectively, can reach the woman after the modified tone and go out man's accent, the marvellous effect that the old and the young put upside down also has tones such as robot, and is very witty, induces one to split with laughter.5.B one of external tapping that machine is equipped with and general home recorder mates and patchcord after general recorder links to each other, make latter's function change the A machine over to, the doll just can tell a story, sings, teaches foreign language, educate one's children or the like.Thereby make the doll become the head of a family's assistant, child's teacher.6.A machine is equipped with two-way switch, when A office closes intercommunication function, the function of then laughing is connected automatically, and child only need touch under doll's neck or arch of the foot, and the loudspeaker in doll's head then sends laugh.7. when A machine intercommunication switch closure, the head of a family can monitor another place and doll child together by the B earphone, can understand in time to the infant especially that it is dynamic.8. design of the present utility model and circuit design can place other various toy figures, can carry out many children's plays, also are applicable to large-scale puppet, advertisement and public place of entertainment.

Fig. 1 is the utility model A machine circuit schematic diagram.

Fig. 2 is the utility model B machine circuit schematic diagram.

The utility model circuit is made up of two extension sets of A, B, and the equal correspondence of each extension set is provided with emission, receiving system, as shown in Figure 1, 2.Wherein the A machine places doll's abdomen.IC1 is a low pressure monolithic FM reception circuit, present embodiment can be selected the TDA7000 type for use, the adjustment capacitor C A3 that is connected on the IC1 pin 6 can change its receive frequency, after the low pass filtering amplifier filtering High-frequency Interference that RA1, RA2, CA11 form, be coupled to IC2 by the audio signal of 2 pin of IC1 output and carry out power amplification by CA12, here IC2 can select LM386 type power amplifier integrate circuit for use, to promote the loudspeaker sounding.Its radiating circuit circuit is made up of BGA1, BGA2, LA2, CA19 etc.Microphone MIC converts audio signal to voltage signal and is coupled to BGA1 colelctor electrode and BGA2 base stage through CA18, because collector junction capacitance CCB1, the CCB2 of BGA1, BGA2 and LA2, CA19 loop are in parallel, the variation of audio signal changes CCB1, CCB2 simultaneously, thereby realized frequency modulation, the audio voltage behind frequency modulation is coupled to antenna by CA20 and launches.Its tranmitting frequency is 90MHZ.Toggle switch KA1 is the working mode selection switch, and when switch placed shown position, this machine was the intercommunication mode, and after KA1 set, intercommunication function just disappears, and the substitute is the mode of laughing.The circuit of laughing is made of IC4 language circuit, and M1, M2, M3 and IC3 etc. form contact witch, make it work when hand IC3 when touching M triggers IC4.IC3 can select the CD4078 type for use in the present embodiment, and IC4 can select the SR8810 type for use.

The B machine also has and overlaps independently sending and receiving apparatus, and different is to be launched after IC modifies tone earlier by the audio signal that MIC or JK1 come in again.IC can select HT8950 specific language modified tone circuit for use, and K1, K2, K3, K4 are the modified tone selector switch, can send Tong Yin, male sound, women sound, robot sound respectively., launched by the modulating emission circuit that BGB1, BGB2 etc. forms after W carries out volume control by the audio voltage that has modified tone of 9 pin of IC output, its frequency is 100MHZ.The receiving circuit of this machine is made up of BGB3, BGB4, BGB5 etc.BGB3, CB9, CB10, LB2, LB3 etc. form superregenerative formula detecting circuit, and BGB4, BGB5 etc. form the audio signal of low discharging circuit after with detection and amplify by JK2 output to promote the work of low-resistance earphone.
