摘要:
A keyboard apparatus constructed to be capable of reducing the depth size thereof and permitting a key unit (UNIT) to be mounted to a key frame (10) with a simple operation. Hinges are extended downward from rear ends of black key main bodies of a black key unit in the vertical direction, and are connected at their lower ends to a common-to-black-keys base end. The black key main bodies are pivotable via the hinges relative to the common-to-black-keys base end in the key depression/release direction. Similarly, white key main bodies of first and second white key units are pivotable via hinges relative to a common base end in the vertical direction. The key frame (10) is formed at its rear portion (10a) with a recessed groove (15) over the entire width of all keys and formed with elastic members extending in the front-to-rear direction on the front and rear sides of the recessed groove (15). Using elastic deformations of the elastic members, a common-to-all-keys base end (20) of the key unit is fitted and fixed to the recessed groove (15).
摘要:
A keyboard structure capable of suppressing a depth dimension of a keyboard instrument and rearward displacements of key main bodies to thereby prevent plastic deformation of hinges. White (27) and black (28) key main bodies are each disposed for pivotal motion around a common base end (20), serving as a key fulcrum, in a key depression/release direction via a hinge (24,25,26) extended therefrom vertically downward. A rear stopper (42) is provided in an intermediate portion of a key frame (10), and a contact portion of a stopper contact member (25a,30a) is in light contact with a front surface of the rear stopper when a key main body is in a key depression initial position. In a key-nondepressed state, when a force exerting toward the rear is applied to a key main body, the rear stopper applies the contact portion with a force exerting toward the front against the force applied to the key main body, thus suppressing a rearward displacement of the key main body.

Klaviatur (1) für ein elektronisches Musikinstrument, umfassend eine Spiellade (3) mit einer Vielzahl darin gelagerter Klaviertasten (2) und eine Vielzahl an der Spiellade (3) gelagerter Hammerköpfe (4), die jeweils über eine Mechanik (5) von einer Klaviertaste (2) antreibbar sind, wobei in der Spiellade (3) jedem Hammerkopf (4) eine elastische, an ihrer Wurzel (7) fixierte Zunge (6) gegenüberliegt, um vom Hammerkopf (4) bei Betätigung der Klaviertaste (2) angeschlagen zu werden, und wobei die Zunge (6) mit einem Anschlagsensor (8) ausgestattet ist, dadurch gekennzeichnet, dass auf der dem Hammerkopf (4) abgewandten Seite der Zunge (6) in einem Abstand (a) zur Zunge (6) ein Anschlag (12) für die Zunge (6) an der Spiellade (3) montiert ist, wobei zumindest im Bereich (9) der Wurzel (7) der Zunge (6) zwischen der Zunge (6) und dem Anschlag (12) ein elastischer Schwingungsdämpfer (13) liegt.
摘要:
A musical keyboard touch sensor pad having a plurality of integrated sensors disposed in an array is disclosed. The plurality of integrated sensors represents a keyboard key. A processor is electronically coupled to the plurality of integrated sensors. The processor is programmed to receive signals from several of the plurality of integrated sensors and to generate a sound signal based on input from the several of the plurality of integrated sensors. The output is variable based on the number in the plurality and the location of the plurality in the array. An audio output device is electronically coupled to the processor to generate a sound based on the sound signal. A keyboard using a plurality of the sensor pads as well as a method of generating sounds from the keyboard are also disclosed.

摘要:
A controller includes an operating member (120) operable by user's depression, and a touch detection device (140) constructed to detect a depressing touch on the operating member. The touch detection device includes a movable contact pattern (PT2) provided on the lower surface (120b) of the operating member (120), and a fixed contact pattern (PT1) disposed underneath the operating member (120). One of the fixed and movable contact patterns is a coil-shaped contact pattern while the other of the fixed and movable contact patterns is a uniform surface pattern, at least one of the fixed and movable contact patterns has flexibility, and at least one of the fixed and movable contact patterns has a surface slanted from the center of the coil toward the outer peripheral edge of the coil. The coil-shaped contact pattern comprises first and second contact elements constituting a dual coil pattern.
