  • Patent number: 7943841
    Abstract: A hi-hat type electronic pad capable of detecting, with reality, an up-and-down motion of a movable pad body that operates similarly to a top cymbal of an acoustic hi-hat, and capable of accurately detecting the operation by one of operation switches which is depressed by a corresponding actuator, even if the movable pad body is moved downward in an inclined state. An operation detecting unit includes a base plate and an elastic member and is provided on an HH pad body. When the HH pad body is moved downward by a pedal operation, the actuators formed on an upper surface of the elastic member and corresponding sheet switches disposed on the base plate are made in contact with one another, whereby operation ON is detected. The sheet switches are formed into an annular shape as viewed in plan.

  • Patent number: 6828494
    Abstract: A rubber pad for an electronic percussion instrument is produced by integrally forming together a pad portion (including a striking surface) and a rim portion, which are colored differently in two-colored formation. In manufacture, the rubber pad is produced by a single press formation using a specially designed metal mold in which a partition wall is arranged between a pad forming cavity and a rim forming cavity, into which rubbers of different colors are respectively put. Therefore, a groove corresponding to the partition wall is formed in a boundary between the pad portion and rim portion, which are integrally interconnected together and are colored differently. Due to the provision of the groove, it is possible to reliably separate different colored regions, i.e., the pad portion and rim portion, from each other. Thus, it is possible to improve external appearance of the rubber pad without substantially deteriorating durability thereof.

  • Patent number: 6815604
    Abstract: An electronic percussion instrument is constituted by a hi-hat, a stand, and a foot pedal, wherein the hi-hat is interlocked with the foot pedal via a movable shaft. In the hi-hat, a core plate (and a core) is arranged in the upper portion, and membrane switches are arranged in the lower portion and are covered with a rubber block, which is gradually brought into contact with membrane switches when depressed by the core plate, which is moved downwards upon depression of the foot pedal. In response to a depressed position of the foot pedal, membrane switches are sequentially turned on or off, thus producing a control signal whose value is varied to control an electronic sound in tone color. Thus, it is possible to produce various hi-hat sounds such as an open hi-hat sound, a closed hi-hat sound, and a foot hi-hat sound as necessary.
