摘要： A musical instrument includes a fixed member; a movable member displaceable in response to a playing operation of the musical instrument, the movable member being displaceable relative to the fixed member from a first state where the movable member is in an initial position to a second state where the movable member is displaced from the initial position; a detectable circuit including a magnetic or conductive body and disposed on the movable member; and a detector circuit including a coil disposed on the fixed member and configured to output a detection signal corresponding to a voltage that is dependent on a distance between the detectable circuit and the coil. A distance between the detectable circuit and the coil in the first state is smaller than a distance between the detectable circuit and the coil in the second state.

摘要： An operation detection device for a key operation of a keyboard device includes a conductive unit configured to be disposed on each of keys, a substrate configured to be disposed facing each of the keys in a pressing direction of the keys. The substrate is provided with a sensor including at least first and second coils, the sensor being configured to be disposed spaced from one key so that at least one of the first or second coil outputs a signal corresponding to a distance between the one key and the respective sensor. The operation detection device includes a detection unit configured to detect a displacement of the one key in at least one of a yaw direction or a roll direction based on signals output from the first and second coils during a key pressing stroke of the one key.

摘要： In a key switch (10), an inner dome (Din) starts to deform once a distal end portion (21) of the inner dome (Din) comes into contact with a base surface (93a) after an outer dome (Dout) starts to deform. A thick portion (25) extending straight and having a uniform wall thickness in a click generating portion (CL) has the thickness less than or equal to the minimum thickness of a thick portion (23) of an after stroke portion (AF). The degree of inclination of the thick portion (25) with respect to a center line (C0) (direction of pressing) is larger than that of the thick portion (23) with respect to the center line (C0) (θc>θa). Before the after stroke portion (AF) undergoes large deformation, the click generating portion (CL) undergoes buckling to cause a sudden decrease in a reaction force and generate a click feeling.

摘要： Embodiments of the invention are directed to an adaptable panpipe instrument and methods of use thereof. In one embodiment, the adaptable panpipe instrument includes a collar brace with a plurality of openings. The plurality of openings may be of the same size or varying sizes and are capable of receiving pipe components of a panpipe instrument. When a plurality of pipe components are positioned within the collar brace in a given configuration, it may be secured to the brace by friction-fit, a webbing, and/or one or more fasteners. One or more of the plurality of pipe components may be adjusted relative to the other pipe components by sliding them up or down which may also adjust the musical scale of that pipe.

摘要： A key structure which has a key formed by a wood part so as to present a woody appearance and which makes it possible to prevent support members thereof that support the wood part from being damaged during machining of the wood part for width adjustment. The key structure functions as a key pivotally moved by key depression when it is mounted in a keyboard apparatus. A wood part includes a narrow part having opposite lateral sides. An elongated upper plate body has opposite lateral sides, and fixedly supports the wood part. Recessed parts are formed in the respective lateral sides of the upper plate body at least in a substantial entirety of a region of the upper plate body in a longitudinal direction of the key structure where the wood part does not exist. The recessed parts are recessed laterally inward of the respective lateral sides of the narrow part of the wood part.
