- the vibration sensor 103 is directly fixed to the back surface of the head 101.
- the vibration sensor 103 only needs to be provided so as to detect the vibration of the head 101. Therefore, for example, as shown in FIG. 13, the vibration sensor 103 can be provided on the back surface of the head 101 via the vibration sensor support 150.
- the vibration sensor support 150 is a component for indirectly supporting the vibration sensor 103 with respect to the head 101, and is configured by forming a metal plate into a bottomed cylindrical shape.
- the vibration sensor support 150 supports the vibration sensor 103 on the back surface of the head 101 via the space S.
- the electronic percussion instrument 100 can suppress damage to the vibration sensor 103 and prevent a decrease in detection accuracy when the player strikes the vicinity of the vibration sensor 103 including the vibration sensor 103 on the hitting surface 101a.
- the vibration sensor support 150 can also be configured by forming an elastic body such as a rubber material and a urethane resin material into a plate shape or a column shape.
- the vibration sensor 103 is provided at the center of the head 101 formed in a circular shape in plan view.
- the vibration sensor 103 only needs to be provided so as to be able to detect the vibration of the head 101. Therefore, the vibration sensor 103 is provided at a location other than the central portion, for example, an edge portion of the head 101 or an intermediate portion between the central portion and the edge portion. be able to.
- the pressure sensor 106 is naturally provided at a position facing the vibration sensor 103.
- the pressure sensor 106 is provided to face the vibration sensor 103, it does not necessarily mean that the central axes of the both are on the same line, and the pressure sensor 106 is located with respect to the center of the vibration sensor 103. In some cases, the centers of these are shifted from each other.
- a plurality of vibration sensors 103 can be provided on the head 101.
- the electronic percussion instrument 100 is composed of an electronic drum.
- the electronic percussion instrument 100 can be widely applied to electronic musical instruments that generate electronic musical tones by detecting vibrations and pressure changes of the striking surface when hit or rubbed with a hand or a stick. Therefore, the electronic percussion instrument 100 can be configured as an electronic cymbal, hi-hat, and percussion.

Abstract
Description
電子打楽器100は、ヘッド101を備えている。ヘッド101は、演奏者による叩く操作や擦る操作によって振動および弾性変形する部品であり、弾性を有する板状体を平面視で円形に形成して構成されている。本実施形態においては、ヘッド101は、樹脂材を薄板状に形成して構成しているが、合成繊維や天然の皮素材などの材料を用いてフィルム状に形成することもできる。
次に、このように構成した電子打楽器100の作動について説明する。まず、演奏者は、電子打楽器100および図示しない外部スピーカをそれぞれ用意した後、電子打楽器100と外部スピーカとを出力端子112を介して電気的に接続する。次いで、演奏者は、電子打楽器100の電源をONにした後、操作パネル111を操作して信号処理装置110を演奏を行なえる演奏モードに設定する。これにより、信号処理装置110は、ヘッド101の振動を検出して楽音を出力する状態となる。
