Abstract
Provided is a percussion instrument including a substantially cylindrical barrel and a weight fixed to the barrel. More specifically, a plurality of weights 5A to 5D may be provided on the inner circumferential surface of a shell 2 of a drum 1 (a percussion instrument). The weights 5A to 5D may be provided at positions where the weights 5A to 5D have four-fold rotational symmetry in the circumferential direction of the shell 2. The weights 5A to 5D may be each provided between lugs 3 that are provided adjacent to each other on the outer circumferential surface of the shell 2.
Claims15
A percussion instrument provided with a plurality of lugs, the percussion instrument comprising:
- a substantially cylindrical barrel;
- and
- a plurality of weights fixed to the barrel at intervals in a circumferential direction of the barrel, with each weight fixed between and spaced apart from adjacent pair of lugs, among the plurality of lugs, which are spaced apart along the circumferential direction of the barrel.
A percussion instrument comprising:
- a substantially cylindrical barrel;
- a weight provided with magnetic power fixed to the barrel;
- a functional part configured to be attached to the barrel;
- and
- a fastening member configured to attach the functional part to the barrel,
- wherein at least one component, among the barrel, the functional part, and the fastening member, contains iron, and
- wherein the weight is fixed to the at least one component due to the magnetic power.
A weight configured to be fixed to a percussion instrument including a substantially cylindrical barrel, the weight comprising:
- a weight body including a hole through which a bolt is to be inserted and having a teardrop shape when seen in the axial direction of the hole,
- wherein the weight body is configured to be fixed to the barrel with the bolt inserted into the hole so that the lengthwise direction of the weight is substantially parallel to the axial direction of the barrel,
- wherein the weight body includes a protrusion protruding toward the barrel, and
- wherein the protrusion is in contact with the barrel when the weight is fixed to barrel with the bolt.
