Abstract
A percussion instrument that suppresses erroneous detection by a rim sensor includes a first plate affixed to a frame, a second plate elastically supported on the first plate by one or more elastic members, and a rim sensor attached to the second plate. Large vibrations of the frame from an impact of a strike on the rim are transmitted to the second plate, and the rim sensor provides an output corresponding to the striking force. Also, vibrations of the frame generated by striking sound or external sound is attenuated by the elastic member, to suppress transmission of such vibrations to the second plate.
Claims30
An electronic percussion instrument comprising:
- a body section that is open on a first side thereof;
- a head provided over the open, first side of the body section;
- a rim that applies tension to the head and is affixed to the body section;
- a rim sensor configured to detect striking on the rim;
- a head sensor configured to detect striking on the head;
- a plate member on which the rim sensor is attached;
- and
- an elastic member made of an elastic material, the elastic member being disposed between the plate member and the body section, and elastically supporting the plate member on the body section, wherein the elastic member is arranged to amplify vibrations of the plate member relative to the body section from a strike on the rim, and suppress transmission of vibrations of the body section to the plate member from the strike on the rim.
An electronic percussion instrument, comprising:
- a body section that is open on a first side thereof;
- a head provided over the open, first side of the body section;
- a rim that applies tension to the head and is affixed to the body section;
- a rim sensor configured to detect striking on the rim;
- a head sensor configured to detect striking on the head;
- a plate member on which the rim sensor is attached;
- and
- an elastic member made of an elastic material, the elastic member being disposed between the plate member and the body section, and elastically supporting the plate member on the body section;
- wherein the plate member has a first surface having a total surface area, wherein the elastic member contacts a contact area on the first surface of the plate member, and wherein the contact area is ½ or less of the total surface area of the first surface of the plate.
An electronic percussion instrument comprising:
- a body section;
- a head supported on a first side of the body section;
- a rim arranged in a fixed relation with the body section;
- a rim sensor configured to detect striking on the rim;
- a plate member on which the rim sensor is attached;
- and
- at least one elastic member disposed between the plate member and the body section, and elastically supporting the plate member on the body section, wherein the elastic material has a greater elasticity than the plate member.
A method of making an electronic percussion instrument comprising:
- providing a body section that is open on a first side thereof;
- disposing a head over the open, first side of the body section;
- applying tension to the head with a rim affixed to the body section;
- providing a rim sensor to detect a strike on the rim;
- providing a head sensor to detect a strike on the head;
- attaching the rim sensor to a plate member;
- and
- disposing at least one elastic member made of an elastic material between the plate member and the body section, and elastically supporting the plate member on the body section through the at least one elastic member, including arranging the elastic member to amplify vibrations of the plate member relative to the body section from a strike on the rim, and suppress transmission of vibrations of the body section to the plate member from the strike on the rim.
