Broadcast message class rocks sounding class, the function without being capable of interaction with baby, it is impossible to meet the demand of parents.
The content of the invention
(1) technical problem solved
In order to solve the above problems, the invention provides a kind of infant's interactive voice toy, the cry of baby is turned
Tone is changed to, adds interactive between baby and toy, initiation to self sound is developed cognitive.
(2) technical scheme
A kind of infant's interactive voice toy, including voice acquisition module, pre-amplifying module, active power filtering module, mould
Number modular converter, processor, D/A converter module, loudspeaker and power supply；The voice acquisition module gathers external sound signal,
The output connection pre-amplifying module, the pre-amplifying module is connected with the active power filtering module, through the modulus
Modular converter connects the processor, the processor output connection D/A converter module, the output connection loudspeaker；
The power supply provides power supply for above-mentioned each module.
Further, believed between the analog-to-digital conversion module and the processor by tri-state latch and NAND gate
Number connection.
Further, the analog-to-digital conversion module uses AD574, and the processor is single-chip microcomputer 8051, the tri-state lock
Storage uses 74LS373, and the NAND gate is 74LS00.
Further, connected between the D/A converter module and the loudspeaker by an external operational amplifier
Connect.
Further, the D/A converter module uses DAC0832, and the operational amplifier uses UA741.
Further, the voice acquisition module is electret digital microphone.
(3) beneficial effect
The invention provides a kind of infant's interactive voice toy, sample code is carried out by the cry to baby, turned
It is changed to corresponding tone to play out, adds interactive between baby and toy, develops baby and self sound is opened
Cover cognitive, there is beneficial effect to the intelligence development of baby.
Brief description of the drawings
Fig. 1 is a kind of structural representation of infant's interactive voice toy involved in the present invention.
Fig. 2 is between the analog-to-digital conversion module and processor of a kind of infant's interactive voice toy involved in the present invention
Connect circuit diagram.
Fig. 3 is between the D/A converter module and loudspeaker of a kind of infant's interactive voice toy involved in the present invention
Connect circuit diagram.
Embodiment
Embodiment involved in the present invention is described in further details below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in figure 1, a kind of baby's voice interactive toy, including voice acquisition module, pre-amplifying module, active power filtering
Module, analog-to-digital conversion module, processor, D/A converter module, loudspeaker and power supply；Voice acquisition module collection external voice letter
Number, output connection pre-amplifying module, pre-amplifying module is connected with active power filtering module, and institute is connected through analog-to-digital conversion module
State processor, processor output connection D/A converter module, output connection loudspeaker；Power supply provides power supply for above-mentioned each module.
Voice signal outside voice acquisition module collection, and input to pre-amplifying module progress gain amplification, it is preposition
Amplification module output feeding active power filtering module carries out smothing filtering, is then fed into analog-to-digital conversion module by the analog signal of voice
Data signal is converted into, the digital quantity being converted into is stored in processor and carries out corresponding coding, is turned according to the height of volume
Be changed to it is euphonic " 1~7 ", be converted to the analog signal of sound again by D/A converter module, and carry out by loudspeaker
Play so that baby can obtain the feedback of oneself sound rapidly while shouting, and add the interaction between baby and toy
Property.
Voice acquisition module is electret digital microphone, and its antijamming capability is stronger, strengthens and external voice is believed
Number sampling efficiency.
Embodiment 2：
Signal connection is carried out by tri-state latch and NAND gate between analog-to-digital conversion module and processor.
Analog-to-digital conversion module uses AD574, and processor is single-chip microcomputer 8051, and tri-state latch uses 74LS373, NAND gate
For 74LS00.
As shown in Fig. 2 logic control signal is sent by 8051 data port P0, and latched by tri-state latch 74LS373
Onto output end Q0, Q1 and Q2, the course of work for controlling AD574.The data output of AD converter is total also by P0 data
Line is connected in 8051, the present embodiment and has only used 8 data ports, therefore 12 data are read into 8051, so ground connection in two times.When
8051 P3.0 is inquired after the conversion end signal of STS ends, is first read the most-significant byte of 12 A/D data after conversion into 8051, so
Low 4 are read into 8051 again afterwards.Here can be to be in startup, conversion and output result regardless of AD574, Enable Pin CE is necessary
For 1, therefore 8051 write line is connected by NAND gate 74LS00 with AD574 Enable Pin CE.
Embodiment 3：
Connected between D/A converter module and loudspeaker by an external operational amplifier.
D/A converter module uses DAC0832, and operational amplifier uses UA741.
As shown in figure 3, DAC0832 is the D/A conversion chips that sample frequency is 8, there is two-stage input to post in integrated circuit
Storage, makes DAC0832 chips possess double buffering, single buffer and lead directly to three kinds of input modes, the need for suitable for various circuits.
Wherein D0~D7 is digital signal input end, and IOUT1 and IOUT2 are DAC current output end, and Rfb is integrated in piece
The feedback resistance of interior external amplifier, VCC is source voltage.DAC0832 outputs are electric currents, and it is voltage typically to require output, institute
UA741 is selected so that operational amplifier in voltage, the present embodiment must also be converted into by an external operational amplifier.
The invention provides a kind of infant's interactive voice toy, sample code is carried out by the cry to baby, turned
It is changed to corresponding tone to play out, adds interactive between baby and toy, develops baby and self sound is opened
Cover cognitive, there is beneficial effect to the intelligence development of baby.
