A frame body fixed to a membraneis divided into multiple long-side frame bodiesand a short-side frame body aligned in a peripheral direction of a frame. Tension is applied to the frame bodyby pulling each frame body. Accordingly, it is not necessary to make the shape of each frame bodyconsistent with the frame(support part) in a complicated polygonal shape, and the shape of each frame bodycan be formed as a linear shape. Therefore, the shape of each frame bodyhardly varies. In addition, even if the shape of each frame bodyvaries, tension can be uniformly applied to the membrane, as it is configured that each frame bodyis pulled to apply tension to the membrane

The disclosure provides a support body, an attachment, and a support method. The support body is in an annular shape for supporting an attachment on a head of a drum and includes a body part in an annular shape configured to be able to directly or indirectly support the attachment, wherein the attachment is configured to be supportable via the body part by making a lower end part of the body part be supported by an edge part of the head.

Support body, attachment, and support method

Provided is an electronic percussion instrument that can facilitate determination of contact of a detection target conductor with a head. An electronic percussion instrument includes: a tubular body portion with an end surface in an axial direction open; a head that covers the open end surface in the axial direction of the body portion and has a front surface adapted to be hit; and a capacitive sensor that has an electrode disposed on a rear surface side of the head, in which the head includes an electrically isolated conductive head, and no conductor connected to a reference potential point is provided between the front surface of the head and the electrode. In this manner, it is possible to facilitate determination of contact of the detection target conductor with the head.

Electronic percussion instrument and manufacturing method of electronic percussion instrument

An electronic percussion instrument capable of simulating a rendition of an acoustic percussion instrument is provided. The electronic percussion instrument includes a housing, a percussion surface attached to the housing, a pressure sensor disposed on a central section of the percussion surface on a side of the back surface and configured to detect pressing against the central section, a head vibration sensor disposed on a peripheral section of the percussion surface on the side of the back surface and configured to detect vibrations of the peripheral section, and a rim vibration sensor disposed at a position overlapping the head vibration sensor when seen in a plan view of the percussion surface and configured to detect vibrations of the housing.

Provided is an instrument pedal device that can be quieter when operated. According to the present invention, a pedal is rotatably supported on a base part by a first shaft. A rotation part is rotatably supported on the base part by a second shaft. A connection part is rotatably supported on the pedal by a third shaft. The connection part is rotatably supported on the rotation part by a fourth shaft. Urging force that is for making the pedal, as rotated from an initial position, return to the initial position is applied by a spring. The pedal can rotate from the initial position to a lowermost position in which the second shaft, the third shaft, and the fourth shaft are in the same plane. The urging force of the spring increases the closer the pedal gets to the lowermost position.

Instrument pedal device and operation method of instrument pedal device

A percussion instrument and a tension applying method are provided. A frame member where an outer edge of a membrane member is connected is arranged at the other side in the axial direction of a frame, and the frame member is tightened radially inward by a tension ring. The frame member has a predetermined elasticity, and a diameter of the frame member is reduced by a tightening force of the tension ring; thus, the tension may be applied to the membrane member by reducing the diameter of the frame member. That is, an edge portion of the membrane member may be uniformly pressed radially inward over the entire circumference by reducing the diameter of the frame member, and thus the tension may be uniformly applied to the entire membrane member.

Percussion instrument and tension applying method

There is provided an electronic percussion instrument including: a body part having an opening on at least one end side of the body part; a head that covers the opening of the body part; a hoop for applying tension to the head, a rim which is disposed on an inner circumferential side of the hoop and of which an upper end is positioned above an upper end of the hoop and of which a bottom surface is supported on an edge of the opening of the body part via the head; and a rim sensor that detects vibration generated when the rim is struck and is disposed in the body part.

There is provided a cymbal damping tool that is attached to a cymbal. The damping tool includes a cylindrical part, a membrane part configured to be a film shape or reticulated and having an inner edge connected to the cylindrical part and disposed on a lower surface side of the cymbal, a frame part that is connected to an outer edge of the membrane part, and a first sensor that is attached to an upper surface of the membrane part.

A bass drum damper and a bass drum are provided. The bass drum damper includes a sound insulating plate that covers a batter head of an acoustic bass drum generating a percussive sound when a beater of a foot pedal percusses a predetermined percussion location. The sound insulating plate includes a contact portion having an opening portion open for the percussion location for the beater and is in contact with the batter head, and a fixing portion provided at a circumferential edge of the contact portion and fixed to a hoop applying a tensile force to the batter head, or the batter head. At least a part of the contact portion which is in contact with the batter head when not being percussed is separated from the batter head at a time of percussing of the beater and is brought into contact with the batter head again after percussing.

The disclosed electronic percussion instrument includes a plate-like pad that has a front surface to be struck, a sheet-like pressure sensor that is provided on a back surface of an outer circumferential end portion of the pad and that detects a pressure change, and a weight portion that contacts a front surface of the pressure sensor, wherein, due to striking on the front surface of the pad, an inertial force from the front surface of the pressure sensor toward a back surface of the pad acts on the weight portion, and the weight portion presses the pressure sensor.

A drum head having a striking feeling similar to an acoustic drum includes an inner head layer and a pair of outer head layers. The outside diameter of the inner head layer is smaller than the outside diameter of a flat part of the outer head layers and the inside diameter of the edge of the shell. The inner head layer is inside the connection part between the flat part and a cylindrical part of the outer head layers and the shell edge part. When tension is applied to the outer head layers, tension is prevented from being applied to the inner head layer.
