Abstract
A stereophonic electric organ is composed of electrically conducting keys, function knobs, 61-key electric organ circuit including LD082, loudspeaker and electrically conducting audio gloves. Said key is made up of electrically conductive polymer. Said gloves is composed of glove and 5 electrical conducting lines connected to relative filters whose output is connected with power amplifier.
Description
Technical field: the present invention relates to a kind of electronic stereophonic organ, belong to electroacoustic keyboard instrument field.
Background technology: at present, the medium-to-high grade electroacoustic keyboard instrument of selling on the market (is example with the mellotron) can not produce the pure stereophonic effect resemble the piano; Even on one deck keyboard, play the melody of same tone color, also can't produce sterephonic (be that the content that left hand is played is pronounced, the content that the right hand is played is pronounced) in the audio amplifier of left side in the audio amplifier on right side.The qin that has in medium-to-high grade mellotron has the tone color of cutting apart pattern, the tone color of can the right-hand man respectively playing a kind of different musical instruments.But both hands can not be crossed keyboard area separately in the process of playing.
Summary of the invention: the objective of the invention is deficiency, and provide a kind of mellotron with stereophonic effect to the personage of music world at above-mentioned technology.This electronic stereophonic organ mainly is made up of conductor keyboard, feature button, operating circuit, loudspeaker and leading note frequency gloves etc.Its concrete structure is: conductor keyboard (4) is to be made by conducting polymer, and special leading note gloves frequently is made up of gloves and five leads.Leading note gloves finger tips (1) frequently joins with an end of arranging shape lead (2), and the junction block (3) of the other end of lead (2) and gloves waist joins.Row's shape flexible circuit conductor or other conductor material that is more suitable for that lead adopts VCD to use.With the single finger direction smoothly of this lead gummed or bury, and at the finger tip place lead guided to outside the gloves with designed conductor finger tip and be connected as a single entity built in gloves inside.The skin of whole lead all requires except that finger tip at the gloves place to insulate, and the finger tip inside of gloves also requires non-conductive.Other feature button, operating circuit, loudspeaker all adopt prior art to design and assemble.Relevant operating circuit adopts the 61 bonding electron qin circuit of being made up of LD082.To use 12 seven grades of binary counter/frequency dividers 4024 in the circuit, can tell 61 vibration audio frequency altogether, each vibration audio frequency export a sound signal through the processing of figure door all through figure gate drive circuit independently, at last this signal is connected under the key
On the shape contact,
The shape contact also adopts lead to be connected with the conduction keyboard.What be complementary with the conduction keyboard is special-purpose leading note gloves frequently.Each wire output end and the corresponding filter circuit of special gloves join.The output terminal of tone filter joins with power amplifier again, and then is connected with loudspeaker.Need put on special gloves before playing stereo qin, lead on the gloves and tone filter input end are connected.Connect the mellotron power supply, can play out music with stereophonic effect.
Advantage of the present invention is: adopting six groups of wave filters, power amplification sound box or under the situation more than six tunnel, can produce the effect of the stero set of similar piano.Just have three (group) loudspeakers in pronunciation as following three sounds of bullet simultaneously, each sound pronunciation source is different; It is stereo and R channel is stereo that the distance of left and right sides two-way audio amplifier has separately just been produced L channel, the six sound channels audio frequency can be input to high-power power amplifier and carry out high-power output, and this point is the inaccessible effect of piano.It can also join with six sound channels DVD video disc maker, is used to make stereo music and appreciates video disc or teaching video disc etc.The keyboard of stereo qin and the special-purpose leading note of playing stereo qin frequently gloves can expanded application in stereo pianotron, stereo electronic synthesizer etc.
Description of drawings:
Fig. 1 is keyboard of the present invention and succusion sounds frequency circuit connection diagram.
Fig. 2 is the block scheme that leading note frequency gloves of the present invention are connected with wave filter, power amplifier and speaker circuit.
Fig. 3 is the leading note of the present invention structural representation of gloves frequently.
Mainly form with reference to Fig. 1,2,3 these electronic stereophonic organs by conductor keyboard, function knob, operating circuit, loudspeaker and leading note frequency gloves etc.Its concrete structure is: conductor keyboard 4 is to be made by conductive plastics, and special leading note gloves frequently is made up of gloves and five leads.Leading note gloves finger tip 1 frequently joins with an end of arranging shape lead 2, and the junction block 3 of the other end of lead 2 and gloves waist joins.Gloves are made by real silk or other material, require solidly, attractive in appearance, wear the comfortable nice and cool mellotron that is suitable for playing.Lead adopts row's shape lead or other conductor material of using in the VCD video disc player that is more suitable for.With the single finger direction smoothly of this lead gummed or bury, and at the finger tip place lead guided to outside the gloves and to be connected as a single entity with finger tip conductor skin built in gloves inside.Relevant operating circuit is mainly formed 61 bonding electron qin circuit by LD082.Will use 12 seven grades of binary counter/frequency dividers 4024 in the circuit, can tell 61 vibration audio frequency altogether, these 61 sound signals are connected to below the corresponding keyboard in the printed board through figure gate circuit independently
Shape carbon membrane contact.The contact
Join by lead and conductor keyboard.Keyboard is complementary with conduction is special gloves.Each wire output end and the corresponding filter circuit of special gloves join.The output terminal of wave filter joins with power amplifier again.Need put on special gloves before playing stereo qin, lead on the gloves and bank of filters input end are connected.Connect the mellotron power supply, can play out music with stereophonic effect.The principle that stereophonic effect produces is: when under the bullet during key,
Vibration audio frequency on the shape carbon membrane contact passes through under the effect of conductive rubber
The contact makes also to have this sound signal on the key face, and the vibration sound signal on the key face is passed through the conductor finger tip of special gloves again simultaneously, enters qin interior tone filter, power amplifier, loudspeaker through thin flexible circuit conductor.When the touching simultaneously of a plurality of fingers, just have a plurality of wave filters, power amplifier in work, thereby produce the effect that is similar to piano.If can select tone color to cut apart pattern, both hands just can played different separately tone colors with any zone on one deck keyboard, and the tone color source of sound that the right-hand man played also separates.As for electronic stereophonic organ bank of filters (every group can be tens kinds even hundreds of tone color filtering), the number of power amplifier and audio amplifier also can be different, minimumly can use two-way filter, power amplifier, loudspeaker, this situation can only be played sterephonic.But it should be noted that the content that the left hand and the right hand are played alone is being not stereo just.Use six path filters, power amplifier and loudspeaker and require two three-finger gloves leads and four the five fingers leads need be merged into a lead separately, use ten groups just can play the music of pure stereo sound effect.Stereo can be two sound channels, also can be multichannel.
