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.

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.

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.

In an electronic drum (1), a head sensor (8) that detects strike to a head (5) and a rim sensor that vibrates a rim (6) and a body part (2) are provided. A velocity (Vc) is calculated based on a peak value (Pc) of the head sensor (8) detected during a scan time (ScT) since a beginning of the strike to the head (2) is detected and an energy value (Er) of the rim sensor (9). The rim sensor (9) detects the vibration of the body part (2) or the rim (6) where the head (5) is provided. Therefore, the sensitivity of the rim sensor (9) with respect to the strike to the peripheral part of the head (5) is higher than the sensitivity of the head sensor (8).

A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

Provided are a control device, a control method and a control system. In a control system (S), a headphone (30) and a pedal device (1) are in communication with each other through first communication (w1), and the pedal device (1) and a portable terminal (50) are in communication with each other through second communication (w2). Accordingly, even when the headphone (30) can be connected to only one control device, a control instruction from the pedal device (1) can be transmitted to the headphone (30) through the first communication (w1), and a control instruction from the portable terminal (50) can be transmitted to the headphone (30) through the second communication (w2) and the first communication (w1).

A rubber hoop 6 includes: a to-be-struck part 60 that is disposed on an upper surface of a head 5; a plurality of insertion parts 61a that protrude downward from the to-be-struck part 60; and hook parts 61b that are formed so as to extend from the insertion parts 61a. Since the hook parts 61b are hooked on a lower surface of the head 5 in a state in which the insertion parts 61a are inserted into a plurality of attachment holes 51 of the head 5, a rubber hoop 6 can be attached to the upper surface of the head 5 while making it unnecessary to form a recessed part in a hoop 7 for hooking the rubber hoop 6 as in the prior art. Consequently, since the radial thickness of the hoop 7 can be reduced, the percussion instrument 100 can be miniaturized.
