Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 1 and Fig. 2, the preferred embodiment of a kind of blind child's music learning machine of the utility model, comprises housing 1, and housing 1 can be placed in back up pad 2, is also provided with interchangeable braille music score 3 in back up pad 2, and braille music score 3 is placed on housing 1 side.Blind child user can as required, upgrade braille music score 3.In the present embodiment, back up pad 2 is collapsible.When use, open back up pad 2; While use, folding support plate 2, can be used for protecting housing 1.
On housing 1, be provided with panel 4, be arranged with some syllable touch key-presss 41 at panel 4, on panel 4, in the region corresponding with syllable touch key-press 41, be provided with corresponding sign, sign is corresponding with the syllable of music.On panel 4, be also provided with speaker hole 42.In housing 1, be provided with circuit board 5, on circuit board 5, be provided with CPU module 51, touch circuit module 53 and D genus audio power amplifier 52, CPU module 51 is controlled and is touched circuit module 53 and D genus audio power amplifier 52, and D genus audio power amplifier 52 output terminals are connected with loudspeaker.
In the present embodiment, CPU module 51 comprises that central authorities process control chip U3, and the model that central authorities process control chip U3 is MSP430F4152 chip.It is the chip of PAM8403 that D genus audio power amplifier 52 adopts model, is the U2 chip in Fig. 2.Syllable touch key-press 41 is capacitance touch button, touches circuit module 53 and comprises touch chip U4 and U5, and the model that touches chip U4 and U5 is TK004 chip.On circuit board 5, be provided with tongue tube (not shown), the dead electricity of circuit and energising on tongue tube control circuit board 5.
As another one embodiment of the present utility model, be also provided with audio input interface in the side of housing 1, audio input interface is connected with audio playing module, and CPU module 51 is controlled audio playing module.Be arranged with record button at panel.The utlity model has playing function, both can play exterior storage music file, simultaneously again can recorded voice the playback of recording, can expand the scope of application of the present utility model.
Please refer to shown in Fig. 3, the U2 chip reality that D genus audio power amplifier 52 uses is PAM8403 chip.PAM8403 is that an output power is the D genus audio power amplifier IC of 3 watts, and it is low that it has harmonic distortion, and the feature that noise crosstalk interference is little makes its playback to sound obtain good tonequality.Employing type, without output and the framework without low-pass filter circuit of being coupled, makes it can directly drive loudspeaker, has reduced taking of whole scheme cost and PCB circuit board space.Under identical peripheral component number, D genus audio power amplifier IC PAM8403 is more far better than the efficiency of class a audio power amplifier, and the endurance that has so just extended battery is the ideal chose of portable equipment (as notebook computer etc.).
Please refer to shown in Fig. 4, it is MSP430F4152 chip that CPU module 51 adopts model.MSP430 chip series super low-power consumption microcontroller is made up of several chip series that have different peripherals for different application target.MSP430 is designed with five kinds of low-power consumption modes, can greatly extend the battery life in portable type measuring equipment.Chip has 16 powerful RISC CPU, and the register of 10 16 and constant generator can improve the efficiency of code to greatest extent.Numerically controlled oscillator (DCO) can wake CPU up in 6 microseconds from low-power consumption mode.MSP430x43x and MSP430x44x series have been joined two built-in 16 bit timing devices, one 12 quick A/D converters, one or two universal synchronous/asynchronous serial communication interfaces.Typical case's application comprises measuring system and control system can be converted to digital value by catching simulating signal, then data is processed and is presented on liquid crystal panel.Timer function can make its configure desired and use in Industry Control, for example waveform counter, Digital motor control, electric energy meter, hand-held instrument etc.Built-in hardware multiplier has strengthened the performance of CPU.
Shown in Fig. 5 and Fig. 6, touching the touch chip U4 of circuit module 53 and the model of U5 is TK004 chip.One touches chip U4 or U5(TK004) come to and can control four road level.
Principle of work of the present utility model is: on circuit board 5, adopt a tongue tube (normally closed) to carry out control circuit switch, attract by magnet.When magnet is during near tongue tube, tongue tube just disconnects, thus circuit dead electricity.Otherwise, when magnet leaves tongue tube, tongue tube closure, circuit obtains electric.
When circuit in electricity condition lower time, in the time that hand touches the syllable touch key-press 41 under corresponding panel 4, output level changes, (in the time not sensing, output level is high level, and in the time sensing, output just becomes low level), syllable touch key-press 41 is just equivalent to a switch.Touch chip U4 and U5(TK004) control respectively DO(1046Hz), RE(1175Hz), MI(1318Hz), FA(1397Hz), SO(1568Hz), LA(1760Hz), XI(1967Hz) Deng Qi road signal, again the signal of these outputs is sent in the I/O of the processing control chip U3 of central authorities, process control chip U3 because corresponding occurrence frequency has been write to central authorities before using, then control and touch different syllable touch key-presss 41, the I/O mouth that makes central authorities process control chip U3 is exported different frequencies, then the frequency of central authorities being processed to control chip U3 output is input to the power amplifier chips U2(PAM8403 of D genus audio power amplifier 52) inner, the sounding of power amplifier control loudspeaker, make the sound of output more true to nature.So just complete one simply by the tone of key control output.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
