Time that manual setting state, that is, band music box can occur by the parent of children according to musical instrument in music and
Position acts the state being manually arranged to each cartoon musician on band music box.The detection of its state and identification side
Method is: when controller identifies that band lamp setting button is to open, and detecting that the corresponding illuminance value of some cartoon musician becomes smaller
After certain time interval T, it is determined as at cartoon musician's head detection hole being covered T time, as a hand with hand for parent
It is dynamic to block, then enter manual setting state.After being greater than T time, cartoon musician starts to do under control of the controller dynamic up and down
Make, until parent will cover T time at cartoon musician's head detection hole with hand again, as secondary manual shade, the card
Logical musician stops doing up and down action under control of the controller.Manual setting state recognition schematic diagram is as shown in Figure 9.Meanwhile by this
The starting of cartoon musician movement and dwell time, corresponding track number and corresponding song play time store the storage to controller
In device.It is to close when controller is identified with lamp setting button, i.e., it is every to be played to the song when music box enters music state
When certain musical instrument sound occurs in some period of purpose, the cartoon musician of corresponding hand-held corresponding musical instrument is moved up and down, and is realized bent
The time and position (i.e. left and right position) and the movement of the cartoon musician of hand-held musical instrument that musical instrument in mesh music occurs walk out of together
It is existing, resolution capability of the culture children to different musical instrument sounds.
It under manual setting state, can once be configured in the actuation time to multiple cartoon musicians and position, i.e., only
Need to be blocked the light detection hole on the cartoon musician head of multiple needs movements with hand.When needing to stop some cartoon musician's
When movement, the light detection hole on cartoon musician head need to be only blocked again with hand.
3. encoding setting state；
The cartoon musician that encoding setting state, that is, band music box can be specified according to children with baton, to band
Each cartoon musician on music box acts the state for carrying out time and position setting.The detection of its state is with recognition methods:
When controller identify band lamp setting button be open when, and detect the corresponding illuminance data variation rate of some cartoon musician with
When the coding set in controller is consistent, it is determined as receiving in children's baton at cartoon musician's head detection hole
Coded laser light spot irradiation, the received illuminance data variation rate of photo resistance is encoded signal, as has received one
Secondary laser code then enters encoding setting state.Cartoon musician starts to move up and down under control of the controller, until children
It is irradiated to cartoon musician's head detection hole with the coded laser light spot that baton issues again, is as had received secondary
Laser code, cartoon musician stop doing up and down action under control of the controller.Realize the function that baton conducts orchestra,
The ability cultivating the musicality of children and conducting orchestra.Encoding setting state recognition schematic diagram is as shown in Figure 10.
Meanwhile by the starting of cartoon musician movement and dwell time, corresponding track number and corresponding to song play time
It stores in the memory of controller.When controller identifies band lamp setting button to close, i.e., music box enters music shape
When state, when certain musical instrument sound occurs in every some period for being played to the song, the cartoon of corresponding hand-held corresponding musical instrument is happy
Hand moves up and down, and realizes time and position that verifying children use baton whether to occur with the musical instrument in song music
Unanimously, and encoding setting state can be reentered, is repeatedly corrected, understanding energy of the training children to music and various musical instruments
Power.
It under encoding setting state, can once be configured in the actuation time to multiple cartoon musicians and position, i.e., only
The LASER SPECKLE issued with baton is needed to irradiate the light detection hole on the cartoon musician head of multiple needs movements.When
When needing to stop the movement of some cartoon musician, only cartoon musician need to be irradiated again with the LASER SPECKLE issued with baton
The light detection hole on head.
4. stage effect state of a control；
While broadcast state, the knowledge of frequency and beat is carried out to currently playing music for stage effect state of a control
Not, driving cartoon musician, which keeps time, generates different colored and brightness variation by music frequency and beat with stage lighting.Its
The detection of state is with recognition methods: when controller identifies that Illuminated Switch key is to open, and band lamp setting switch key is pass,
Music box enters and then enters stage effect state of a control after broadcast state, and the port ADC of controller and MP3 module loudspeaker export
End connection carries out data acquisition to music is played, and carries out Fast Fourier Transform (FFT) operation to the data of acquisition, calculates
The frequency component of current music out is stored into memory.The time of some frequency component occurred every time according to low-frequency range can
Calculate the beat of the song.According to beat, controller calls the starting of cartoon musician movement and dwell time, corresponding song to compile
Number and corresponding song play time data, drive each cartoon musician to move up and down by the beat of the song；According to frequency model
It encloses and beat, controller generates 6 channel PWM waveforms of different in width, control and driving RGB LED light, make it by frequency senior middle school
The speed of low difference and beat carries out color and brightness change.
Above-described embodiment is the preferable embodiment of the utility model, but the embodiments of the present invention is not by above-mentioned
The limitation of embodiment, it is made under other any spiritual essence and principles without departing from the utility model to change, modify, replacing
In generation, simplifies combination, should be equivalent substitute mode, is included within the protection scope of the utility model.
