Abstract
An LED festoon lamp-based laser harp is composed of a harp frame (1), a laser device (2), a control device (3) and an LED festoon lamp module (4). Four keys are arranged on the harp frame, namely a power source key for controlling the on/off of a whole system power supply and three keys for controlling the tone of sounds emitted by the laser harp. The three keys include a high pitch key, an alto voice key and a bass key. By operating different keys on the whole system, a player can play music pieces with three tones on the same musical instrument. The defect that a conventional musical instrument can only emit a single tone is prevented. Meanwhile, the LED festoon lamp module arranged on the harp frame can achieve different flickering effects according to different musical scales. The playing effects on the stage are further enhanced.
Description
Technical field
The present invention relates to a kind of laser harp based on LED color lamp, one does not have string specifically, but laser can be relied on to get light beam, by the finger of people through a kind of laser harp based on LED color lamp of beautiful music just can be sent, belong to intelligent instrumentation field.
Background technology
Harp is a kind of large-scale plucked instrument.Harp is plucked string instrument the most ancient in the world, and early stage harp only has the string by diatonic scale arrangement, and institute's tonality of playing is limited.Owing to having abundant intension and beautiful tonequality, harp becomes chromaticity musical instrument special in symphony orchestra and musical drama, and what mainly serve as is the decoration sentence of harmony accompaniment and glissando formula, often plays out the pen of crucial touch, makes audience be difficult to forget.In indoor, harp is also important solo instrument.Lyric section or the cadenza of soft grace can be played out during solo, have appeal.Modern harp is all console mode, and shape is huge, range and piano similar.Harp be the product that is combined with music of hyundai electronics science and technology it play important role in contemporary music, single-chip microcomputer has powerful controlling functions and programming realization characteristic flexibly, and it has dissolved in the life of modern people, becomes an irreplaceable part.Given this, we use single-chip microcomputer to design laser harp, utilize single-chip microcomputer to produce different frequency to obtain the scale of our requirement, finally arbitrarily can play the music wanting to express.
Summary of the invention
Technical matters to be solved by this invention is, a kind of laser harp based on LED color lamp is provided, during work, laser gets light beam irradiation in photoresistance, and staff, through out-of-date, blocks light beam, change the resistance of photoresistance, single-chip microcomputer is which light beams is blocked by reading the magnitude of voltage change judgement of photoresistance, and exports the low and high level of corresponding frequencies at I/O mouth, thus sends the sound of different frequency.Adopt advanced laser technology to produce the harp of light sensation, beautiful music can be played.
The technical solution adopted in the present invention is: a kind of laser harp based on LED color lamp is made up of qin frame (1), laser aid (2), control device (3) and LED color lamp module (4), good looking appearance, simple fashion is the ideal equipment of stage performance, daily entertainment life.
Described qin frame (1) adopts transparency and the extremely strong acrylic of hardness to make qin frame.
Described laser aid (2), is made up of generating laser and photoresistance, and Laser emission part adopts M658D200 generating laser, the common photoresistance of photoresistance to be resistance be 10K.
Described control device (3) is made up of main control chip, power amplifier, loudspeaker, and main control chip adopts AT89C2051 single-chip microcomputer as main control chip, and power amplifier adopts KA2206 chip, and loudspeaker adopts 3W/8 Europe loudspeaker.
Described LED color lamp module (4) is seven LED color lamps, changes during system works along with the change of seven syllables.
accompanying drawing explanation
Fig. 1 is the outside drawing of a kind of laser harp based on LED color lamp of the present invention;
Fig. 2 is a kind of laser harp control principle drawing based on LED color lamp of the present invention;
To be that a kind of laser harp frequency based on LED color lamp of the present invention is corresponding with syllable show Fig. 3.
Embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described.
As shown in Figure 1, a kind of laser harp outside drawing based on LED color lamp of the present invention, a kind of laser harp based on LED color lamp is made up of qin frame (1), laser aid (2), control device (3) and LED color lamp module (4), qin frame having four buttons, is that power key for controlling whole system on/off and three are for controlling the high key of the tone height of sounding needed for this laser harp, middle key and bass buttons respectively.Whole system by the operation to different buttons, can be played the music of three tones, has broken away from traditional playing an instrument and can only play the constraint of single tone on player can play an instrument at one.Meanwhile, the LED color lamp module on qin frame can make different flicker effect according to different performance syllables, adds its playing effect before the lights.
As shown in Figure 2, a kind of laser harp control device block diagram based on LED color lamp of the present invention, is made up of main control chip, power amplifier and loudspeaker.During system works, laser gets light beam irradiation in photoresistance, and single-chip microcomputer reads the voltage (about 0.27v) of photoresistance, and now, its logic level is 0.Staff, through out-of-date, blocks light beam, and when photoresistance is irradiated without laser tube, single-chip microcomputer reads the voltage (about 2v) of photoresistance, and now, its logic level is 1.Single-chip microcomputer is which light beams is blocked by reading the magnitude of voltage change judgement of photoresistance, and the low and high level of corresponding frequencies is exported at I/O mouth, the low and high level of this frequency is by the amplification of power amplifier, the last sound being sent corresponding frequencies by loudspeaker according to the low and high level of different frequency, thus reaching the effect of performance, people just can hear the sound of music.
As shown in Figure 3, frequency of the present invention is corresponding with syllable to be shown, and plays and by the operation to button, a musical instrument can be played the music of different tone.
A kind of laser harp structure based on LED color lamp of the present invention is simple, is easy to operation, also along with the LED color lamp that change is colorful while sending music, has certain practicality and sight.
Claims (3)
1. one kind is made up of qin frame (1), laser aid (2), control device (3) and LED color lamp module (4) based on the laser harp of LED color lamp, it is characterized in that: also comprise on qin frame and have four buttons, is that power key for controlling whole system on/off and three are for controlling the high key of the tone height of sounding needed for this laser harp, middle key and bass buttons respectively.
2. a kind of laser harp based on LED color lamp according to claim 1, is characterized in that: the LED color lamp module on qin frame can make different flicker effect according to different performance syllables, adds its playing effect before the lights.
3. a kind of laser harp based on LED color lamp according to claim 1, is characterized in that: whole system by the operation to different buttons, can play the music of three tones on player can play an instrument at one.
