Description of drawings
Fig. 1 is the optics lyre electricity structure block diagram of present embodiment tone adjustable function.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made a detailed description.
With reference to figure 1, a kind of optics lyre of tone adjustable function comprises laser emission element, optics receiving element, single-chip microcomputer, scale selection key, phonation unit, power supply unit; Be connected by laser between laser emission element and optics receiving element, when laser connects when disconnecting, the optics receiving element sends look-at-me and gives single-chip microcomputer, and single-chip microcomputer receives look-at-me and also controls phonation unit output sound of musical instrument; The scale selection key is connected with single-chip microcomputer, is used for to the control information of single-chip microcomputer input scale; Power supply unit is connected with single-chip microcomputer, is used for providing working power.Laser emission element comprises 7 laser lamp heads, and the optics receiving element comprises and 77 photoresistance that the laser lamp lamp holder is corresponding that look-at-me is 7 kinds.
Laser lamp head adopts LD-K650A23.Laser emission element comprises 4 LM358 that are connected with single-chip microcomputer, photoresistance.Phonation unit is hummer.
Power supply unit comprises 4 joint 1.5V dry cells, four joints and adopts tandem-type connection to form the 6V direct supply, forms the power supply that the 5V direct supply is used for whole device after voltage stabilizing.
It is the LD-K650A23 laser lamp head that laser emission element comprises seven models, and its anodal parallel connection method that adopts is connected its minus earth with the 5V DC power source unit.Send seven 650nm invisible lights after the energising respectively, the distance between per two invisible lights is 3 centimetres, and every invisible light corresponding photoresistance one by one;
It is 4 of LM358 operational amplifiers that the optics receiving element comprises model, and model is 5516, and light resistance 5K Ω dark resistance is 7 of 0.8M Ω photoresistance.Laser emission element sends invisible light and is radiated in the photoresistance after the energising work, because photoresistance is compared with prefabricated resistive voltage receiving illumination different its node voltages of resistance when unglazed.LM358 output high level when accepting illumination, output low level when unglazed.And the output port of each LM358 respectively described single-chip microcomputer IO mouth link to each other as, the LM358 output port is connected to single-chip microcomputer P1.0-P1.6 respectively.In addition, the prefabricated current potential of optics receiving element can be regulated by potentiometer, in order to appropriate threshold voltage is set;
Single-chip microcomputer adopts the STC89C51 single-chip microcomputer, and the scale selection key is three.The STC89C51 single-chip microcomputer includes pre-set programs one cover and sends different tones for the control phonation unit.Three scale selection keys are connected with one-chip machine port P21, P22, P23 respectively, and other disconnecting ground is designated as high, medium and low three kinds of different scales respectively, is used for regulating the tone of different scales.
Single-chip microcomputer sends level pulse, and under the different situation of the pulsed frequency of hummer reception, the sound frequency that hummer sends also can be different.In addition, three buttons that control module comprises have been preset three different tones scale just by software, and the sound frequency of each three scale improves gradually.The sound that people's ear is heard is the sound of musical instrument that frequency improves gradually.When three some buttons of button were pressed, its corresponding single-chip microcomputer IO mouth current potential will be dragged down, and reads single-chip microcomputer IO mouth state by the single-chip microcomputer pre-set programs, and then the pulse of output different frequency realizes tone adjustable function of the present utility model to hummer with this.
Laser emission element sends invisible light, can stop when staff is stirred that invisible light that described laser emission element sends is radiated in the photoresistance on the optics receiving element between string, and then cause the potential change of photoresistance.After the current potential of photoresistance changes, to single-chip microcomputer IO mouth, judge corresponding string by pre-set programs by the LM358 output low level on the optics receiving element, further send level pulse control phonation unit and sound.
The pre-set programs of single-chip microcomputer is mainly the different pulse of output frequency, because different pulsed sound frequency differences, the sound height that people's ear is heard is also different, and then forms seven kinds of different musical notes of DAO RUAI MI FA SAO LA XI.
Protection domain of the present utility model is not limited to the scope that embodiment explains, and all belong in the protection domain of the present utility model based on the change of the present utility model thought.
