  • Patent number: 9390697
    Abstract: An electronic drum head is provided that attaches to a standard acoustic drum shell. The drum head is a self-contained unit that replaced both the acoustic drum head and the drum hoop or rim to convert the acoustic drum into an electronic drum. When the drummer plays these heads, the drum head is muted, minimizing acoustic noise from the kit. Also, these electronic drum heads can be easily attached and removed, allowing the drummer to go back to playing his acoustic drums when desired.

  • Publication number: 20150206518
    Abstract: A snare assembly tensioning and locking mechanism for holding snare wires in either a contact or non-contact position against a bottom drum head of a snare drum. The mechanism uses a lever mounted horseshoe shaped clip including surface bumps or protrusions that, when the lever is in an upward and locked position, engage a set of complementary notches on a surrounding peripheral surface of a snare wire tension adjusting knob. In alternate embodiments, the locking lever may pivot toward the drum or in a direction tangential to the drum. In this manner, the snare wires are held in tension against inadvertent loosening of the tension adjusting knob while the drum is played.
