Abstract
The utility model provides a novel electronic musical instrument--a musical instrument in the form of a blanket. The utility model is characterized in that the main body of the musical instrument is a piece of blanket, the back side of the blanket is provided with a plurality of contact switch devices composed of electric conductive rubber and printed circuit boards, and the traditional music instrument buttons are replaced with the contact switch devices. A main circuit board which is provided with a circuit of an electronic organ is also arranged on the same side of the blanket. The utility model is externally connected with a power amplifier and a device for supplying power to the main circuit board, and is flatly placed on a bed, the ground or a stage generally when used. When a patent dance is performed, the performance is carried out through touching the contact switch devices by feet, and music is produced; so the dance and the music are performed at the same time; the utility model can be also placed on a table or hung on a wall and can be played by hands.
Description
The utility model provides a kind of new-type electronic musical instrument---blanket qin.The characteristics of this qin are that the main body of qin is a blanket, the back side of blanket be equipped with much by conductive rubber and printed circuit board (PCB) forms contact switch device controlled, with the traditional key of this device replacement.
The structure of this qin and playing mode all are different from existing keyboard-type electronic musical instrument.Existing keyboard-type electronic musical instrument is the same with traditional keyboard musical instrument, represents the key series arrangement of corresponding scale, and the player flicks and hits key and play, and can only perform a composition, and can't carry out nautch or dancing exercise simultaneously.The utility model not only can the same independent performance the with keyboard type electronic organ, but also can be played in dancing by the performing artist.
The utility model is finished as follows: the main body of blanket qin is a folding blanket of softness, can be woollen blanket, carpet, felt etc.The blanket size depends on the needs, require scales payable many should use greatly some.The one side of blanket be fixed with some by conductive rubber and printed circuit board (PCB) form contact switch device controlled, disconnect usually.There is contour pattern at another side and the corresponding position of contact making device at blanket.Contact switch device controlled being connected to the multiply flexible cord on the main circuit board that circuit of electronic organ is housed, this circuit board also are installed in contact switch device controlled with on the blanket simultaneously.
The power supply of blanket qin and audio power amplify to be finished in two ways: (1) is equipped with the horn box (active audio amplifier) of power amplifier, the required power supply of main circuit board also thus the power supply in the horn box provide.Main circuit board is connected with a triple core wire with horn box.(2) do not have the tape cassete of magnetic-tape core, with the magnetic head position contacting on a coil is installed.The button silver oxide cell also is housed, to power, with the same mode of the connected mode of main circuit board (1) in the tape cassete to main circuit board.During use tape cassete is put into the cassette holder of sound-track engraving apparatus, selected " tape " working method.When playing, the sound signal of main circuit board output is finished the power amplification effect by the coil-induced magnetic head of giving through sound-track engraving apparatus.Concerning main circuit board, dual mode is general, can adopt wherein a kind of mode as required.
In order to judge the duty of main circuit, can also not adopt above-mentioned dual mode, be with the piezoelectric buzzer sheet of resonant cavity to monitor and only connect one, the button silver oxide cell is housed in the resonant cavity powers to main circuit board.
When tramping with one's feet contour pattern on the blanket when the performing artist is dancing, corresponding contact switch closure produces corresponding scale signal or music signal with circuit of electronic organ on the main circuit board that it is connected, again through power amplifier generation melody.Can also be put into this device on the desk or be suspended to flick on the wall and play.
If adopt corresponding circuit of electronic organ or music circuit, can be with this device as usefulness such as the comprehensive exercising machine of dance music, disco dancing exercising machine, child music Enlightenment device, music carpet, music wall tapestries.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is contact switch device controlled basic view.
Fig. 3 is contact switch device controlled cut-open view.
Fig. 4 is a circuit block diagram of the present utility model.
Referring to Fig. 1, on the contact switch device controlled one side that is fixed on blanket (3), this face is the A face, and another side is the B face, and the number of contact switch device controlled (1) can require according to the scale of the circuit of electronic organ that is adopted to select, and the position is evenly distributed.The main circuit board (2) that circuit of electronic organ and peripheral cell be housed also is fixed on the edge of (3) A face after with the polyfoam parcel.Connect with thin stranded conductor between each contact switch device controlled (1) and between contact switch device controlled (1) and the main circuit board (2).One three core socket is housed in order to output sound signal and the required power supply of introducing main circuit board (2) to be amplified on the main circuit board (2).Audio-frequency power amplifier and to main circuit board electric supply installation (4) (hereinafter to be referred as the device (4)) dual mode can be arranged: (1) band power amplifier horn box, it carries out power amplification with the sound signal of main circuit board (2) output, promote sound horn, and supply with main circuit board (2) power supply.It is connected to three core sockets of main circuit board (2) by the triple core wire of a band plug.(2) tape cassete of the unrecorded tape core of button silver oxide cell and inductive coil is equipped with in inside, and the button silver oxide cell is powered to main circuit board (2).Coil is installed on the position near magnetic head, and this device is put into the cassette recorder cassette holder, and magnetic head can be sensed the sound signal of passing through in the coil during work, by the power amplifier and the sound horn of sound-track engraving apparatus.This device is identical with first kind of mode with the method for attachment of main circuit board (2), can select one of them as required.
Referring to Fig. 2, Fig. 3, conductive rubber (a) is bonded together with bonding agent with printed circuit board (PCB) (b).Conductive rubber contact (a) is depressed when being subjected to external force, and the switching circuit on the printed circuit board (PCB) (b) is connected, and after external force was cancelled, conductive rubber contact (a) by elastic reset, this had installed the effect that is equivalent to key.
Contact switch device controlled in order to protect (1), main circuit board (2) and profile attractive in appearance; with contact switch device controlled (1) and main circuit board (2) be fixed on blanket (3) go up and be connected finish after; with a plastics fabric envelope to blanket (3) A face; edge and blanket (3) are fixing, only three core sockets on the main circuit board (2) are exposed.
The position of contact switch device controlled for the ease of discerning (1) and profile attractive in appearance, printing and dyeing have the contour pattern corresponding with the position of contact switch device controlled (2) on blanket (3) the B face.
During contour pattern on the performing artist tramps with one's feet blanket (3), corresponding contact switch device controlled (1) closure, main circuit board (2) produces corresponding sound signal and sounds through device (4).
