Abstract
The utility model discloses a voice control music cradle, which comprises a cradle, wherein a bracket is connected with the cradle; a rolling wheel is arranged at the bottom of the cradle; a voice input device and a sounding device are arranged on the cradle; the cradle is connected with a motor through a rod component; the voice input device is connected with a single chip machine; the single chip machine is connected with a driving circuit and the sounding device; and the driving circuit is connected with the motor. The voice control music cradle is formed by adding voice sensing and music playing functions in the cradle in daily life. When a baby wakes up with a start and cries in the cradle, the cradle can automatically shake and play music, and then the baby stops crying and falls asleep again.
Description
Technical field
The utility model relates to a kind of cradle, is specifically related to a kind of acoustic control music cradle.
Background technology
Bed, function that cradle in the daily life is equivalent to the baby are comparatively single.When the baby cries and screams in cradle, often need big people to shake cradle, musical instruments performance song to tease it sleeping.So just need big people to keep, limited people's daily routines on the cradle next door.
Summary of the invention
The utility model technical problem to be solved provides a kind of acoustic control music cradle; Add sound induction and music playback function in the cradle in daily life; When the baby in cradle, wake up with a start, when crying and screaming; Cradle can shake and playing back music voluntarily, makes the baby can stop to cry and shout, and falls asleep once more.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: the acoustic control music cradle, comprise cradle, and cradle is connected with support, and the cradle bottom is provided with roller, and cradle is provided with speech input device, sound equipment, and cradle connects motor through rod member;
Said speech input device connects single-chip microcomputer, and single-chip microcomputer connects drive circuit and sound equipment, and drive circuit connects motor.
Said drive circuit is a H bridge-type motor-drive circuit.
Said drive circuit adopts the LM298 chip.
The utility model acoustic control music cradle, drive circuit are H bridge-type motor-drive circuit, control rotating and reverse of motor.
When the baby cries and screams, be placed on the speech input device of cradle head, as: microphone, can receive signal, thereby give high level of single-chip microcomputer, trigger and interrupt, whether the single-chip microcomputer time-delay detects sound and exists, and sob disappears and does not then carry out action; Have the startup timer regularly as if sob, drive motors is made motor and is moved back and forth simultaneously, can feed back to position quantity of single-chip microcomputer during motor movement, when the then counter motion of motor arrival forward maximum, on the contrary positive movement.Motor moves back and forth and shakes through rod member drive cradle.Meanwhile, drive sound equipment and put one section music.After single-chip microcomputer regularly finishes, detect vagitus once more, have sob then to continue above-mentioned flow process, noiseless motor and the sound equipment of then closing.In above-mentioned running, can turn off everything through button.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model structure drawing of device;
Fig. 2 is the utility model device H bridge-type motor-drive circuit;
Fig. 3 is the utility model device control circuit figure;
Fig. 4 is the utility model device speech processing circuit figure.
The specific embodiment
The acoustic control music cradle comprises cradle 1, and cradle 1 is connected with support 2, and cradle 1 bottom is provided with roller 3, and cradle 1 is provided with speech input device 4, sound equipment 7, and cradle 1 connects motor 6 through rod member 5.
Said speech input device 4 connects single-chip microcomputer, and single-chip microcomputer connects drive circuit and sound equipment 7, and drive circuit connects motor 6.Drive circuit is a H bridge-type motor-drive circuit.Drive circuit adopts the LM298 chip.
As shown in Figure 3, be the control core with ATMEGA16, lm298 is a motor-drive circuit.
Voice signal and microphone input; After capacitor C 4 couplings, carry out the one-level voltage follow by operational amplifier; Budget amplifier U5 and diode D1, D4, capacitor C 12 is formed envelope detection circuit, obtains the waveform profiles of voice signal; Operational amplifier U8 and capacitor C 15 are formed filter amplification circuit with resistance R 20, single-chip microcomputer is convenient in little voice signal amplification is detected and the high frequency clutter is filtered out.The signal of finishing dealing with is received the PA0 mouth of single-chip microcomputer, and PA0 is the AD thief hatch of single-chip microcomputer, and the analog voltage signal that reads in converts data signal into through AD; When signal arrives to a certain degree greatly; Single-chip microcomputer carries signal to give lm298, makes motor 6 actions, and timer internal starts simultaneously.
Lm298 can accept standard TTL logic level signal VSS, and VSS can connect 4.5～7 V voltages.4 pin VS connect supply voltage, and VS voltage range VIH is+2.5～46 V.Output current can reach 2.5 A, can drive inductive load.The emitter stage of 1 pin and 15 underfooting pipe is drawn separately respectively so that insert current sampling resistor, forms current sensing signal.L298 can drive 2 motor, OUT1, and OUT2 and OUT3 can connect motor 6 respectively between the OUT4.
A, B (corresponding pin 6,11) are the port of control control signal, just Enable Pin.Lm298 has 4 signal input and output ports, and A, B respectively control two, has only the input signal of signal input port 1,2 when A is high level (corresponding pin 5,7) to control motor 6 through signal output port (pin two, 3) output effectively.
Single-chip microcomputer is given 6 pin and the 11 pin high level of lm298, enables output, if IN1=0, IN2=1 motor A just changes, if IN1=1, IN2=0 motor A counter-rotating, if IN3=0, IN4=1 motor B just changes, if IN3=1, IN3=0 motor B counter-rotating.Thus can be through baby's sob control cradle action.
As shown in Figure 4, signal has microphone P input, because the signal of microphone is to obtain by changing its this life resistance, we utilize lm317 (voltage-stablizer) chip; Made a constant-current source, signal input P changes its this life resistance, thereby changes the constant-current source parameter; Make signal stabilization receive external disturbance little, and signal has 50 times amplification, through the C1 coupling, operational amplifier U_356_1 is a voltage follower; Operational amplifier U_356_2 amplifies 20 times with signal again, makes voice signal that certain volt value can be arranged, and forms envelope detection circuit through diode D1, resistance R 7 with capacitor C 2, extracts the envelope curve of signal; Resistance R 8, capacitor C 3 is formed filter circuit with operational amplifier U_356_4, isolates low frequency signal; Afterbody, operational amplifier U_356_3 is flourishing in the normalization voltage range of AD with signal, supplies single-chip microcomputer to receive.
