Description

Use the mellotron of infrared laser key

Technical field

The utility model relates to electronic musical instrument and makes the field, particularly about a kind of mellotron that uses the infrared laser key.

Background technology

Market electronic organ kind is a lot, add specialty performance senior standard electronic organ that foot-operated tone color control to the standard recreation electronic qin that 61 keys are arranged to being provided with double key from the children electronic organ that has only 8 scale keys, what use all is to press the mode that key is played, and this also is the performance operator scheme of continuing to use in the world wide.

96116300.3,97206358.7, No. 200820191550.6 names of Chinese patent are called the method for making of having introduced several electronic laser qins in the publication document of laser musical instrument and have all used the laser beam that luminous LASER Discharge Tube is sent in visible-range of red, green or other colors to substitute traditional key bar none to play, have practicality and operability, but use visible laser can see laser beam as the spectators under the key bandstand, lose the mystique and the unpredictability of action when playing, existed the defective that reduces spectators' enjoyment.Up to now, the not visible infrared laser beam of end user's naked eyes substitutes string and yet there are no pertinent literature report and commodity selling with the infrared laser key mellotron that sounding by the key control scale carries out music playing.

Summary of the invention

The utility model provides a kind of mellotron that uses the infrared laser key, this qin has been installed a cover and has been erect the frame infrared laser performance piano key board of playing operation on traditional keyswitch type electronic qin, during use, the player rotates up 110 ° with the frame infrared laser piano key board that keeps flat, the laser keyboard is just erect the top that is fixed on the mellotron body, add that the infrared laser pipe sends the infrared laser beam that a rule is provided with by required scale number vertically downward in proper order from the inboard, upper edge of frame in the power supply after-frame, form the infrared laser key, the player points the infrared beam of arbitrary the corresponding scale of representative of blocking, all can send the musical sound of same scale when pressing in the qin with common key, when the player puts on the infraluminescence finger-stall and contacts infrared laser key beam, infrared lumious material on the finger-stall can send red under the irradiation of infrared laser, green, the dazzling light of multiple different colours such as indigo plant, cooperate the performance of melody, played up the artistic effect of playing greatly.

Find the position of infrared laser key accurately for convenient habit qin person, be provided with in the laser tube of frame infrared laser piano key board outside and represent 1,2, many groups of a 3...7n scale tactic red, orange, yellow, green, blue or green, blue, scale sign luminotrons of seven kinds of colors of purple and the scale sign of black font, the neutral place is installed by a visible laser positioning power valve at interval at each infrared laser key beam, utilize the beam of visible laser to make the practitioner find the accurate position of infrared laser key beam accurately at interval, also can play the effect that when style is played, increases artistic effect simultaneously.

The utility model is achieved through the following technical solutions above-mentioned purpose.A kind of mellotron that uses the infrared laser key, comprise the qin body, common piano key board, frame infrared laser piano key board, the infrared laser power valve, infrared laser key beam, the infrared laser receiving element, music signal shaping trigger circuit, the infraluminescence finger-stall, visible laser location power valve, as seen locating laser bundle, scale sign luminotron, scale signs etc. are formed, it is characterized in that: above the qin body, be equipped with rotatable 110 ° and stand vertically the frame infrared laser piano key board of playing use, the inboard order in frame infrared laser piano key board upper edge is installed and is counted the infrared laser power valve of launching infrared laser key beam downward vertically of setting according to required scale, infrared laser power valve exterior face is equipped with scale sign luminotron and scale sign to player's direction, the infrared laser pipe is equipped with visible laser location power valve at interval and forms straight line laser, and infrared electro receiving element corresponding with the tube-launched infrared laser key of infrared laser beam spot and the music signal shaping trigger circuit that are connected with Music Clip in the qin body are housed in the qin body.When practicing qin, energized, the infrared laser power valve all powers up and sends row's infrared laser key beam, visible laser location power valve sends row's visible laser bundle simultaneously, the player is with reference to the scale mark position of being illuminated by scale sign luminotron, finger is pressed in the neutral gear of intrafascicular of per two visible lasers and can interdicts infrared laser key beam, the interior corresponding photovalve by blocking infrared laser key beam of qin body just produces a pulse by 0 to 1 and exports, after handling, music signal shaping trigger circuit deliver to the Music Clip in the mellotron, send and demarcate the corresponding musical sound of scale, just formed dulect melody by the continuous performance of song.Can close visible laser location power valve after playing skillfully,, make finger when performance, touch visible locating laser bundle, produce the visual art effect of multiple flash of light when carrying out to open visible laser emission positioning pipe according to actual needs when the style art is played.

Described infrared laser power valve uses the near-infrared band Laser emission diode of operation wavelength in the 850-1080 nanometer range, selects for use in the emissive power 10-300 milliwatt, and the infrared light spot diameter is not more than 3 millimeters.

Described infrared laser photoelectric receiving device uses near infrared photodiode or the silicon photocell device of operating wavelength range in the 850-1080 nanometer, and the device diameter is not more than 10 millimeters.

Described visible laser location power valve uses the laser diode that sends ruddiness, emissive power 1-5 milliwatt.

Described scale sign luminotron uses the LED luminotron of red, orange, yellow, green, blue or green, blue, purple seven kinds of colors, 3 millimeters of calibers or use patch light-emitting diode.

The beneficial effect that the utility model produces is: the playing mode that has increased mellotron, produced mystique and the luminous visual sense of beauty of finger when player's finger knocks the sightless key of human eye in the space, improved the interest and the art of electronic organ performance and played up power.
