Since a bell sensor (14) is mounted to the lower surface of a bell portion (12a) via a bell frame (13), vibration caused by a strike on the bell portion can be transmitted to the bell sensor via the bell frame. Therefore, even if the bell portion is struck in the directly above vicinity of the bell sensor, the output value of the bell sensor can be suppressed from becoming extremely large. Since the bell frame is connected to the lower surface of the bell portion along the circumferential direction, even if the bell portion is struck at a position away from the bell sensor in the circumferential direction, vibration caused by the strike is easily transmitted to the bell sensor via the bell frame. Therefore, the sensitivity distribution of the bell sensor for a strike on the bell portion can be made uniform regardless of differences in striking position.

Provided are an electronic percussion instrument and a mounting method of a sensor that are capable of accurately detecting a strike on an edge part of a striking surface. An edge frame (17) to which an edge sensor (18) is mounted is connected to the lower surface of a bow portion (12b). Therefore, in the case where the edge part (struck portion (17a)) of the bow portion (12b) is struck, a striking surface frame (12) and the edge frame (17) can be integrally swung with respect to a rod (4). As a result, the relative height between the outer edge of the bow portion (12b) and the struck portion (17a) is less likely to change during performance, making it possible to accurately detect vibration caused by a strike on the edge part of the bow portion (12b) with the edge sensor (18).

In an electronic drum (1), a power saving transition level (Lb) when transitioning to a power saving mode is stored, a level when returning to a normal mode is calculated according to an estimated envelope (SE) based on the power saving transition level (Lb) and a power saving duration from the power saving mode to returning to the normal mode, and a strike processing is performed based on the calculated level when returning to the normal mode. Thus, even immediately after returning from the power saving mode to the normal mode, a level of a strike envelope (HE) can be calculated using the level when returning to the normal mode calculated from the estimated envelope (SE), and the strike processing can be appropriately performed by using the calculated level of the strike envelope (HE).

Provided is a clamp (1) that includes: a housing (2) for holding a holding object (100), and upper and lower claws that protrude forward from the housing (2) and are capable of gripping an object by adjusting an up-down spacing. A lower surface of the upper claw (251, 252) is formed with an upper clamp surface (240, 250) recessed upwardly, and an upper surface of the lower claw (3) is formed with a lower clamp surface (40) recessed downwardly. The upper clamp surface (240, 250) formed between a rear end of the upper clamp surface (250e) and a front end of the upper clamp (250f) surface is positioned above the rear end and the front end of the upper clamp surface. The lower clamp surface (40) formed between a rear end of the lower clamp surface (40c) and a front end of the lower clamp surface (40d) is positioned below the rear end and the front end of the lower clamp surface.

A sensor module (Sa, Sb) for electronic wind instrument of the disclosure includes a main flow path (314a, 315a, 323, 326, 355) positioned between an air inlet (310, 311) and an exhaust port (334, 335) for exhaled air formed on an outer surface of a housing (32, 33) of an electronic wind instrument (1, 201); a branch flow path (356, 380) branching to intersect with the main flow path; and a sensor (360, 363) positioned in the branch flow path and detecting changes in airflow in the branch flow path caused by changes in exhaled air flowing in the main flow path. A cross-sectional area of a first opening (356a, 380a) of the branch flow path formed at a connection portion between the main flow path and the branch flow path is smaller than a cross-sectional area of the main flow path at the connection portion.

An electronic wind instrument (1) includes an index value calculating part (500) and a performance control part (501). The index value calculating part is configured to calculate an intensity index value (Vr) corresponding to a first exhaled air intensity (V1) based on an intensity of exhaled air blown into a first air inlet (310) and a second exhaled air intensity (V2) based on an intensity of exhaled air blown into a second air inlet (311) provided in proximity to the first air inlet. The performance control part is configured to start sounding of a musical sound based on an other pitch that is a pitch different from a key pitch in a case where the intensity index value calculated by the index value calculating part is equal to or greater than a first pitch change threshold (Tcrd), the key pitch being a pitch corresponding to an operation on an operator.
