Abstract
An input device for an electronic musical instrument, has blown air apertures and suction air apertures alternately disposed on the front face of its main body. This input device also has elastic members provided within the blown air apertures and suction air apertures, in such a way as to be deformed by the force of the air caused to flow through said blown air apertures and suction air apertures. The input device also has magnets or pressure members serving as operation members, which magnets or pressure members are each displaced by an elastic member, and a plurality of musical tone input switches are driven by the displacement of the magnets or pressure members.
Claims15
An input device for an electronic musical instrument, comprising:
- a main body having a plurality of ducts,
- a plurality of actuators arranged to be driven by air sucked into and blown out of said plurality of ducts, and caused to flow through said ducts;
- and
- a plurality of musical tone input switch means associated with said ducts, each of said switch means including a conductive movable member arranged to move according to the actuation of each of said plurality of actuators by the air flowing through said ducts, an a stationary contact member arranged to produce a contact signal upon contact with said conductive movable member.
An input device for an electronic musical instrument, comprising:
- a main body having a plurality of ducts;
- a plurality of actuators, each of which comprises an elastic member having one end secured within a corresponding one of said ducts and the other end arranged to extend obliquely through the interior of the duct, and a permanent magnet provided on said elastic member for movement in accordance with the movement of said elastic member when elastically deformed by the air which flows through said duct, and
- a plurality of musical tone input switch means associated with said ducts and arranged to be driven by said plurality of actuators.
An input device for an electronic musical instrument, comprising:
- a main body having a plurality of ducts and an air blowing/sucking portion in which the respective openings of said ducts are arranged in a row;
- elastic members provided within said ducts, each of which has a bending portion deformed by the force of the air blown out or sucked in, with each of said bending portions being integrally formed by a connecting portion;
- operation members, each of which is provided on a corresponding one of said elastic members, being displaced when said elastic member is defomed by the force of the air blown out or sucked in;
- and a plurality of musical tone input switch means, each of which is driven by a corresponding one of said operation members when the same is displaced.
