Abstract

PIANO KEYBOARD FOR USB KEYBOARDS AND MIDI CONTROLLERS. WEIGHTED KEYS ARE USED TO IMITATE PIANO KEYS, AND THE APPLICATION DESCRIBES A KEY WHICH INSTEAD OF WEIGHTS USES A SPRING. THE SPRING (1) (FIG. 1) IS FORMED AS A BOTH ' TO A STIFF DIAGONAL CENTER PART (2) WITH ANGLEED ENDES (3) THAT TRANSFORMES INTO LEAF SPRINGS (4) .HOW THE ANGLE BETWEEN CENTER PART AND END AFFECTS TWO OPPOSITE FORCES THAT PULL ON THE VEHICLES NARROWS AND IN (FIG. 3) AN ANGLE NEAR THE VERTICAL LOCKS THE ENDS, WHILE AN ANGLE OF 45 DEGREES (FIG. 1) FUNCTION AS A RESISTANCE THAT DECREASES WHEN THE CENTER PART IS TURNED. FOR EACH KEY ON A GIVEN PIANO, THERE IS A LENGTH AND ANGLE IN THE CENTER OF THE SPRING THAT IS BETTER THAN ANY LENGTH AND ANGLE COPIES HOW IT FEELS IN A FINGER, LEAF SPRINGS SIMULATE A PRESSED KEY.

Description

DESCRIPTION PIANO KEY FOR USB KEYBOARDS AND MIDI CONTROLLERS. WEIGHT KEYS ARE USED TO IMITATE PIANO AND WING, AND IN THE APPLICATION DESCRIBES A KEY WHICH INSTEAD OF WEIGHTS USES A SPRING TO MAKE A KEY ON A PIANO.

THE SPRING (1) (FIG. 1) IS SHAPED AS AN 'N' AND MADE OF A THIN METAL BAND, PRESSED AND BENDED INTO A STIFF DIAGONAL CENTER (2) ATTENDED END (3) AS IN 1so GRADERS BÖJARBJÖR ) WITH A RADIUM THAT CURVES OUTSIDE. THE SPRING (1) IS UNDER THE KEYCHAIR LEVER AND IT BOTH ENDS THE FIXTURE ANGLE SPRING EXTERIOR END (5).

THE SPRING HAS A DIAGONAL CENTER AND TWO VERTICAL ENDS, AND HOW THE ANGLE BETWEEN THE CENTER AND END AFFECTS TWO OPPOSITE FORCES SUMMER AT THE ENDS SHOWN IN (FIG. 2) AN ANGLE NEAR ANY NEAR AN ANGLE NEAR VERTICAL LOCKS THE ENDS, WHILE AN ANGLE OF 45 DEGREES (FIG. 1) FUNS AS A RESISTANCE WHICH DECREASES WHEN THE CENTER IS TURNED. For each key on a given PIANO IS THERE a length and an angle of the spring central portion that better ÄNNÅGON OTHER length and angle COPY how it feels a finger Närman Press it on the piano, as there is a RADIUS / width / thickness / shape of the leaf spring WHICH BETTER THAN ANY RADIO / WIDTH / THICKNESS / SHAPE COPIES WHAT HAPPENS WHEN THE KEY IS RELEASED. THE LEAF SPRINGS (4) SHOULD SIMULATE A PRESSED KEY ON ANYTHING INSIDE RADIE INCREASES WHEN A KEY IS PRESSED AND DECREASES WHEN THE KEY IS RELEASED. THE RADIE OF THE LEAF SPRINGS (4) THEREFORE INCREASES BEFORE THE LEAF SPRINGS (4) BEGINS TO TURN THE CENTER OF THE SPRINGS (2) AND ANGLEED ENDS (3), AND THE PLAY IN THE KEY IS DETERMINED BY THE LEAVE 4 THE RADIATION PRESSES THE LEAF SPRING (4) MOTHER'S KNEE (6), WHICH DIVIDES A LEAF SPRING (4) INTO TWO PARTS, WHICH RADIUM REDUCTIONS ARE FOR ITSELF. THE RADIUM OF THE SHORTER STIFFER PART (7) BETWEEN THE MIDDLE PART (2) AND KNEE (6) REDUCES LESS IN RADIUM THAN THE LONGER PART (s) BETWEEN KNEE (6) AND MOUNTING (5), AND KNEE ( THE SHEET SPRING (4) KEEPS A RADIUS UNTIL IT IS TURNED UP TO ANY KNEE OUTSIDE A KNEE (6).

THE MIDDLE OF THE MIDDLE PART (2) AND THE ANGLEED ENDES (3) STRENGTHENING CONSISTS OF TWO RECTANGULAR EALS (9) (FIG. THE EALS (9) ARE TURNED DIFFERENTLY SO THAT THE STRENGTHS ARE LOCATED ON EACH SIDE AROUND THE BLADE JOURDS (4) AND SERVE ILODLED AS SUPPORT FOR THE MIDDLE OF THE ANGLED SHOULDER END (3).
