Abstract

The utility model relates to a music device, which is widely used for the display of music and colorful light of stages, dance halls, concert halls, theaters and household acoustic devices, the teaching aids of music teaching and creating, the musical devices of the deaf-mutes, etc. The utility model provides with a thyristor driver which can simultaneous receive the sound moderate signals of an audio amplifier and the high-low level signals of a sampling and data processing unit, and the high-low level signals are decided by the sound frequency. Thus the signals whose sound frequencies are from 27Hz to 4096Hz are transformed to 88 colourful bulbs which are disposed with 9 groups in the longitudinal direction and 12 groups in the lateral direction and are displayed by the ways of colours and shading levels. Thus the music effect is added, and at the same time, the deaf-mutes can enjoy music by the utility model whose structure is simple.

Description

Music-colour lighting transducer

The utility model relates to a kind of musical instruments, and the music colour lamplight that it is widely used in the stereo set of stage, dance hall, music hall, arenas and family shows, the teaching aid of music teaching and creation, and deaf-mute's musical instruments etc.

As everyone knows, common musical instruments, for example: recorder, stereo set, music Karaoke, music staff printer etc., main purpose are to be convenient to Music Appreciation and to increase beautiful music effect to a certain extent.In fact, the sense organ of accepting music is not limited to the sense of hearing, the people is to the power of light, color with to the volume of sound, the sensation of frequency, exist closely-related contact, above-mentioned existing musical instruments all is to go to experience music by the sense of hearing merely, can not appreciate and enjoy the whole glamour of music, in addition, the deaf-mute can't music appreciating.

In view of this, the purpose of this utility model is the weak point that exists at existing musical instruments, propose a kind of music-colour lamplight interpreter, it comprises: sound transducer, audio frequency amplifier, FV convertor, sampling and data processing unit and scr triggering device.Frequency and intensity with a voice signal are controlled two controllable silicons respectively, are subjected to a controllable silicon of FREQUENCY CONTROL to be used to connect colored electric lamp bulb, are subjected to a controllable silicon of strength control to be used to control the brightness of bulb.Thereby can increase the inspiration of people frequency of sound wave 27～4096Hz corresponding to 88 kinds of colour lamplights to music, open people's " the music visual field ", the abundant and abundant effect of music, and also structure is simple again, cost is low.

In order to realize the purpose of this utility model, the utility model comprises: sound transducer 1, audio frequency amplifier 2, FV convertor 3, sampling and data processing unit 4, it is characterized in that: the scr triggering device 5 that is provided with the high-low level signal of the intensity of sound signal of accepting audio frequency amplifier 2 simultaneously and sampling and data processing unit 4, controllable silicon (T1 ... T88) and corresponding bulb (L1 ... L88) the corresponding parallel circuits that forms in parallel, and controllable silicon T is connected in the above-mentioned parallel circuits, in addition, 88 colored electric lamp bulb (L1 ... L88) by vertical 9 groups, horizontal 12 arrangements, laterally the bulb colour is yellow from left to right, yellowish green, green, blue green, blue, blue purple, purple, purplish red, red, blood orange, orange, and vertically following supreme (tone from low to high), from dark (deeply) to the light plate of bright (shallow).

Fig. 1 is embodiment system block diagram of the utility model.

Fig. 2 is an embodiment controllable silicon drive circuit of the utility model figure.

It is as follows with reference to Fig. 1, Fig. 2 in detail an embodiment to be described in detail:

FV convertor 3 is connected into monostable circuit with integrated stamen sheet 555, and it is triggered by the unknown frequency input signal, exports a Fixed width pulse then, exports to sampling and data processing unit 4 after filtering.

Sampling and data processing unit 4 in order to improve the frequency discrimination precision, have been adopted 8796 type single-chip microcomputers, and its precision is 10 bits, is binary system from 0 to 1023(

B), respective frequencies 0 to 4096Hz, the sampled value of 1Hz correspondence is 1023/4096 ≈ 1/4.The frequency of every signal lamp correspondence, form and aspect, form and aspect shading value.Sample bits mouth A, mouthful B data, wherein frequency range is to get (referring to table 1) according to each sound standard frequency, sampled value scope one hurdle is the numerical value that single-chip microcomputer is obtained by the A/D interface.The data that collect are integer values that are directly proportional with incoming frequency; According to this numerical value, can determine from the mouth A of single-chip microcomputer and the data of mouthful B output, and these data be exported with output order.Because 10 accuracy A/D conversion can only be distinguished the difference of 4Hz, the frequency synthesis of low for frequency, that difference is little several sounds, and lamp number, color are all constant, allow them can distinguish change together in the scope, are used as a unit and control.

Scr triggering device 5, this driver mainly are to realize the conversion of music signal to the colour lamplight signal, audiorange difference wherein, and light coloring is just different, and loudness of a sound determines the lightness both sides of light to carry out synchronously.(referring to Fig. 2)

1. control the brightness of lamp with intensity of sound.

The A point is that voice signal is through sound transducer 1 and audio frequency amplifier 2 back outputs.Loudness of a sound is high more, and the voltage between A, B is big more, under the controllable silicon conducting good more, flow through 88 in parallel bulb (L1 ... L88) electric current in is just big more, and this bulb is also just bright more.88 bulbs in parallel are that bulb brightness changes with sound intensity by a power supply power supply between BC.

2. audio frequency is controlled the switch of 88 bulbs.

88 bulb (L1 ... L88) not simultaneously bright, but determine the unlatching of pairing bulb, the bulb of the corresponding a kind of corresponding color of the frequency of each sound, the bulb (L1 of 88 corresponding 88 kinds of colors of audiorange according to the difference of audio frequency ... L88).

8796 type single-chip microcomputers from sampling and data processing unit 4 collect the frequency of sound, export one or more high level Ei(i=1 after treatment, 2 ... 88), control controllable silicon (T1 ... T88) one or more connection in, make one or more bulb (L1 ... L88) brightness changes for example with the power of sound: when 8796 type single-chip microcomputers are exported to current potential that E1 orders and are high level, controllable silicon T1 connects BF, constitute the loop of bulb L1, the brightness that makes bulb L1 changes with the power of sound.

Music of the present utility model-colour lamplight interpreter utilizes the frequency of a voice signal and intensity to control two controllable silicons respectively, is subjected to the controllable silicon of FREQUENCY CONTROL to be used to connect bulb, is subjected to the controllable silicon of strength control to be used to control the brightness of bulb.According to scientific discovery, 88 sounds have almost comprised the range of all musical instruments, according to color and tone, tone color, the corresponding relation of loudness of a sound, 88 music signals are transformed into corresponding colour lamplight signal, the arrangement of bulb (referring to table 1) is divided into nine groups, (the 1st group of every group of 12 colored electric lamp bulb, the 9th group special), color is yellow from left to right, yellowish green, green, blue green, blue, blue purple, purple, purplish red, red, red, orange, orange, pairing form and aspect are consistent, difference is the difference of form and aspect shading value, with tone (order from 1 group to 9 groups) from low to high, the lightness of bulb color is correspondingly step by step from dark (deeply) to bright (shallow) (is standard with the standard color card).Thereby make the music mark become a kind of visual information, accepted by people visually, simultaneously, make that people can learn from a new angle, research and music appreciating.
