  • Patent number: 7112738
    Abstract: An electronic musical instrument which can realize a choking effect by a simple operation. The electronic musical instrument is constructed such that a neck provided with a fingerboard is fixed to a body. A plurality of (twelve) fret operating elements are provided for each of six sounding channels. The body is provided with a string input section and an arm, and six stringed operating elements are provided for the respective sounding channels. For each sounding channel, a tone generator generates a musical tone at a pitch determined by the corresponding fret operating element and in sounding timing determined by the corresponding stringed operating element. When the arm is operated, a CPU provides control to apply a choking effect to a musical tone for a sounding channel, in which the musical tone is being sounded, by raising the pitch of the musical tone by a predetermined amount.

  • Patent number: 4669349
    Abstract: An electronic drum has a drum body, a drumhead, a support/tension mechanism, a closed space forming member, a vibrating plate, and a piezoelectric element. The closed space forming member forms a closed air space together with the drumhead lower surface. The vibrating plate is fitted to the closed space forming member so as to divide the closed air space into plural closed air spaces. One of the divided plural closed air spaces existing between the lower surface of the drumhead and the vibrating plate serves as a transmission space. When the drumhead is struck, the vibration of the struck drumhead is transmitted to the vibrating plate via the transmission space. By this transmission via air space, same vibration at the vibrating plate is obtained irrespective of the struck portion of the drumhead if struck by same striking force. The piezoelectric element converts a pressure produced based on a mechanical vibration of the vibrating plate to an electrical signal.

  • Patent number: 4226156
    Abstract: An electric percussion instrument having at least one drum head is provided with a mute assembly arranged near the drum head and at least one mechanical-electric convertor containing a vibration responsive pickup element is incorporated into the mute assembly. Direct collection of the drum head vibrations via the mute assembly successfully precludes undesirable mixing of external vibratory noises which are transmitted to the drum frame.
