  • Patent number: 10276141
    Abstract: Provided are an electronic percussion instrument and a control device thereof. The electronic percussion instrument includes central and peripheral sensors, first and second waiting devices, and a sound production instruction device. When the central sensor detects a strike earlier than the peripheral sensor, the first waiting device performs a first waiting process for a first predetermined time after the central sensor detects the strike. When the peripheral sensor detects a strike earlier than the central sensor, the second waiting device performs a second waiting process for a second predetermined time after the peripheral sensor detects the strike. The sound production instruction device instructs production of a striking sound after the first waiting process of the first waiting device ends, or after the second waiting process of the second waiting device ends if the central sensor has not detected a strike within the second waiting process of the second waiting device.

  • Patent number: 10255895
    Abstract: There is provided an electronic percussion instrument. The electronic percussion instrument includes a struck surface and a plurality of strike sensors configured to detect a strike on the struck surface. The plurality of strike sensors include at least one central sensor that is disposed on a back side of the struck surface and disposed at a center side of the struck surface and a plurality of peripheral sensors that are disposed on a peripheral side of the struck surface. The central sensor and the peripheral sensors each have the same structure. The peripheral sensors are configured to transmit a strike signal in a shorter time than the central sensor when the struck surface is struck.

  • Publication number: 20190066646
    Abstract: 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.

  • Patent number: 10163426
    Abstract: 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.

  • Patent number: 10147409
    Abstract: Provided is an electronic percussion instrument that is capable of simulating a playing technique for an acoustic percussion instrument. A tubular body part is opened on an axial end surface, and a head is attached to the axial end surface to be struck on the front surface. A capacitance sensor includes an electrode that generates a capacitance with respect to a detected conductor, such as a human body, positioned on the front surface side of the head. Because the capacitance sensor detects a change of a capacitance corresponding to a distance between the electrode and the detected conductor, whether the detected conductor approaches (contacts) the head or presses the head can be determined. As a result, the playing technique for the acoustic percussion instrument is simulated.
