Description

Child's music safe chair toy structure

Technical field

The utility model discloses a kind of toy, particularly a kind of electronic program, some control acoustic toy are applicable to child's music safe chair toy structure.

Background technology

In the nursery chair toy of on market, selling, roughly be divided into three parts.A part is with the main display form of being shaped to of nursery chair toy, utilize the moulding of nursery chair toy to express a kind of specific meaning, can only from static state, go to appreciate and have a taste of the expressed meaning of nursery chair toy, the amusement scope is extremely narrow, give simple vision entertainment effect, and give stiff sensation easily.Another part is that action with toy on the modeling and adding of nursery chair toy is jointly as display form, this type of nursery chair toy is expansion to some extent aspect expressed content, simultaneously also can give certain imagination and have certain lively change shape, but still only some expansions have been arranged in the scope of vision amusement, but the time of playing with has been grown, and puies forward not high child's interest.Third part is the moulding with the nursery chair toy, action, sound is together as the technique of expression, the action and the sound of nursery chair toy are controlled by circuit, circuit is then by the mechanical switch control that places nursery chair toy figure surface, because mechanical switch is higher than the surface of nursery chair toy figure, and need certain activity space, these have not only destroyed the complete of nursery chair toy figure, and reduced the aesthetic effect of nursery chair toy figure, though this a part of nursery chair toy is owing to added vocal function, strengthened the entertainment effect of toy, but toy can only be from the beginning to the end according to the permanent order sounding, the sounding content also can only be expressed a complete meaning, can not form the effect of an interactive sounding, the time has been grown to produce too to produce and has played with fatigue.

The purpose of this utility model is will expand and the amusement function of strengthening the nursery chair toy, and a kind of novel nursery chair toy is provided, and makes child can eliminate fatigue in amusement, enriches child's life.Produce the effect and the effect of an interaction by the moulding of nursery chair toy and the child of sounding content and participation.

Summary of the invention

The technical solution of the utility model is achieved in that child's music safe chair toy structure, comprise child's main body and safe chair, child's main body can be positioned on the safe chair, it is characterized in that adding in the internal circuit of described toy the music integrated circuit chip, and by formula selector switch, ripple pearl switch and audio-switch input control, output promotes sound horn.

The utility model number described music integrated circuit IC selects the CS06020 chip for use, and the supply voltage of circuit is 3.0V, and power supply provides voltage by VDD to the CS06020 chip of solid music integrated circuit IC.The PRA0-PRA3 of described music integrated circuit IC is an input port, and wherein PRA0 is that formula is selected input, and PRA1 is ripple Zhu Kaiguanshuruduankou, and PRA2 is the input port of sound control; Triggering key when PRA3 is TRYME, the output control terminal COUT output of music integrated circuit IC connects the pronunciation loudspeaker.

The PRA0 end of described music integrated circuit IC then enters the PLAY state when being high level, the PRA0 end then enters the TRYME state when being low level.When entering the PLAY state, the PRA1 of described music integrated circuit IC holds the ripple pearl switch on and off that connects, and then the output control terminal COUT of solid music integrated circuit IC output connects the pronunciation loudspeaker, the broadcast music.When entering the PLAY state, the ripple pearl switch on and off that the PRA1 of described music integrated circuit IC end connects three times, then the output control terminal COUT of music integrated circuit IC output connects the pronunciation loudspeaker, plays music.

When the PRA2 end of described music integrated circuit IC was low level, the output control terminal COUT output of music integrated circuit IC connected the pronunciation loudspeaker, plays music.

When the PRA2 end of described music integrated circuit IC was high level, the output control terminal COUT output of music integrated circuit IC connected the pronunciation loudspeaker, plays music and child's morbid sound.

The triggering of the PRA3 end TRYME of described music integrated circuit IC is strong, after music integrated circuit IC enters the TRYME state, presses to trigger and is good for, and music integrated circuit IC output control loudspeaker are play music.

The output control terminal COUT of described music integrated circuit IC is the audio-frequency current output, and the audio-frequency current signal adds to the base stage of triode S8050 and amplifies, and promotes sound horn.

The utility model compared with prior art has expansion and the amusement function of strengthening the nursery chair toy, a kind of novel nursery chair toy is provided, make child in amusement, can eliminate fatigue, enrich child's life, and produce the effect and the effect of an interaction by the moulding of nursery chair toy and the child of sounding content and participation.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

Specific embodiment

Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1 and Figure 2: electronic program, some control acoustic toy by ectosome, place interior circuit triggers end in outer surface or surface and internal circuit to form.It is the toy that adds sounding component such as solid music integrated circuit, language integrated circuit, simulated sound integrated circuit and peripheral circuit in the toy ectosome, as long as triggering the circuit triggers end of toy can sound, increase entertainment effect, and strengthened the expressive force of toy.Circuit is made up of sequence circuit, sounding content choice control circuit and sound signal amplifier, and the supply voltage of circuit is 3.0V.The core of circuit is to take voice single-chip microcomputer (seeing left figure CRADLE BABY) wherein IC pin position VDD1 and VDD2 are the positive source power supply; IC pin position GND1 and GND2 are the power cathode power supply; The external oscillation resistance Rosc=220K of IC pin position OSC.

IC pin position PRA0～PRA3 is an input port.Wherein PRA0 is that formula is selected pin, then enters the PLAY formula when this pin is high level, then enters the TRYME formula when this pin is low level; PRA1 is ripple Zhu Kaiguanshuruduankou, and after IC entered the PLAY state, logical-disconnected three times of ripple pearl switch was then play music; PRA2 is a sound control input end mouth, and when this pin was connected high level, loudspeaker were play music+BABY compound voice, and when this pin was low level, loudspeaker were only play music; Triggering when PRA3 is TRYME is strong, after IC enters the TRYME state, presses this and is good for, and loudspeaker are play music.

IC pin COUT is the audio-frequency current output, and sound signal adds to the base stage of triode S8050 amplifies, and promotes sound horn.
