Description

Electrodynamic type multifunctional baby cradle

Technical field:

The utility model relates to the multi-functional automatic control type bassinet that a kind of family uses, and particularly a kind ofly realizes waving automatically electrodynamic type multifunctional baby cradle with music based on single-chip microcomputer and sensor control motor and speech chip.

Technical background:

Traditional bassinet all is to adopt manually to push away the mode of shaking both at home and abroad at present, and hanging basket, shaking table etc. are arranged, and the head of a family needs expensive energy to go nurse, fool the child that sleeps, and using wastes time and energy.A spot of automatic cradle occurred on the market now yet, but adopted the few of single-chip microcomputer and sensor control, control ability is not strong automatically.Some installs watch-dog on cradle, cost is higher, is not suitable for promoting; Some transmission is too simple, and it is unreliable to use for a long time; Some installs transmission device on basket body top, safety coefficient is low; Also some utilizes equilibrium principle to form automatically to wave, need balancing pole etc., influence the attractive in appearance of cradle itself; The not installation music player that has, and music can improve baby's intellectual development, also can promote well the baby very fast enter sweet and beautiful dreamland.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming that exists in the prior art, seek a kind of modern electronic technology that utilizes of design preparation and control conventional cradle, realize cradle swing and music playing function automatically, alleviate nurse baby's labour intensity, simultaneously also built the sleep environment of a comfortable health for the baby, safe and reliable.

For realizing the purpose of foregoing invention, the utility model agent structure comprises loudspeaker, the recording mouth, speech chip, recording switch, microphone, the shaking table body, single-chip microcomputer, motor, motor start switch, broadcast/stop key and indicator lamp electric connection combine, be divided into shaking table body and control circuit two parts, at conventional shaking table body bottom one end motor is installed, the output revolving force of motor becomes oscillatory forces output through conventional mode conversion and docks with the shaking table body by bar linkage structure, be shaped on microphone in one jiao of inboard, shaking table body top, another angle, top is shaped on loudspeaker and recording mouth, speech chip and single-chip microcomputer respectively with microphone, loudspeaker, recording mouthful electric connection and making sheet become monomer to place shaking table body bottom, with recording switch, broadcast/stop key, starting switch and indicator lamp arrange the control panel of making the mode structure and with the single-chip microcomputer electric connection, control panel is installed on shaking table body one side or is installed on the table of being convenient to nurse personnel control.Control circuit part of the present utility model mainly is made up of sound transducer and pre-amplification circuit, Schmidt's generator, single-chip microcomputer, audio record circuit and motor circuit five parts.The signal pre-amplification circuit is formed by triode, resistor, capacitor, power-supply battery and switch combination, power circuit is connected with switch and is connected to the base stage and the colelctor electrode of triode respectively by two resistors, is connected to resistor between the base stage of triode and the colelctor electrode; Microphone one end ground connection is connected on the base stage of triode behind the one end series capacitor.The peripheral circuit of pre-amplification circuit, Schmidt's generator and speech chip prints pcb board by blueprint drawing, thereby realizes integrated circuit, minimizing volume; Motor-drive circuit and the single-chip microcomputer of having programmed insert the circuit that has printed by chip carrier, and motor two inputs are welded on two outputs of drive circuit respectively.Control panel adopts the moulding of cartoon down toy, and three buttons are in the shelter of toy, avoid by baby's mistake by.

When the utility model uses, closed power switch, circuit is started working.Baby crying sound is input to amplifying circuit by microphone and Schmidt's generator amplifies rectification, and the signal after the processing is sent into single-chip microcomputer, and single-chip microcomputer is according to program controlled motor work and the speech play finished writing in advance.Motor circulates under the driving of drive circuit just to be changeed, reverses, and the bed body is vacillated now to the left, now to the right thereupon, and voice playing circuit is emitted beautiful music simultaneously; When the baby did not cry, single-chip microcomputer postpones an end made motor and sound circuit not work after the time, and cradle stops to shake.User's manual operation control panel is pressed K1, and the music that the typing user likes is pressed K2, realizes that loudspeaker plays. and press once more and promptly stop playback.Press K3, machine operation, cradle shakes, and presses promptly once more to stop.Utilize sound transducer that baby crying sound is converted into current signal and send into single-chip microcomputer, shake and music by single-chip microcomputer timing controlled cradle.

During baby crying, sound converts current signal to by microphone U5, amplifies through the rectification of transistor T 3 and Schmidt's generator again, produces pulse signal and sends into single-chip microcomputer, after the single-chip microcomputer received signal, output high-level strobe drive circuit, drive circuit output output signal is just changeed motor, behind the time-delay certain hour, output signal makes the motor counter-rotating again, the certain hour of delaying time again repeats this process, drives cradle and waves.Single-chip microcomputer gating speech chip is exported high level and is made speech chip drive the music of depositing in the loudspeaker broadcast chip simultaneously.When the baby stopped to cry, front end circuit did not have input signal, did not just have output signal, single-chip microcomputer detects less than signal, and after delay a period of time, output low level makes motor out of service, export high level simultaneously and make speech chip not by gating, loudspeaker stops output.

The utility model is compared with existing cradle, and is multiple functional, convenient and practical both by baby crying acoustic control system, avoided the trouble of manually shaking, and can Artificial Control start, and melody can freely be recorded by the user, and intelligence has more hommization.
