ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to percussion instruments that produce a rattling sound, and more particularly to an improved hand-held percussion instrument that produces that sound when shaken.
There is continual need for percussion instruments that produce different and highly audible sounds. There is also need for such instruments capable of producing sound effects which vary depending upon which portion of the instrument is grasped, and when the instrument is shaken.
SUMMARY OF THE INVENTION
It is a major object of the invention to provide an improved percussion instrument meeting the above needs.
Basically, the improved instrument of the invention comprises:
a) first and second shells each of which extends away from the other, the shells forming cavities, the shells having an interconnection region,
b) a closure for one of the shells closing a portion of the cavity formed by said one shell, the closure spaced from said interconnection region,
c) a cavity formed by the other of the shells being open at one end thereof in a direction away from the interconnection region,
c) and loose pellets contained in the cavity formed by the one shell, the pellets freely movable to impact the one shell and diaphragm portion to produce a rattling sound when the instrument is shaken.
A further object is to provide at least one divider separating the cavities formed by the two shells.
It is another object of the invention to provide such an improved percussion instrument wherein at least one of the shells, and preferably both shells, have conical configuration, and are metallic.
Yet another object is to provide such shells which diverge in opposite directions away from said interconnection region whereby the closure may be located at one extreme end of the instrument on one shell, and wherein the opposite end of the instrument is maintained open, as at the largest end of the other shell, for transmission of rattling sounds, with “megaphone” effect.
An additional object is to provide a method of use of the instrument, which includes
e) grasping a selected portion of the instrument,
f) shaking the instrument to produce a selected rattling sound, depending on such grasping.
As will be seen, such selected grasping may include covering the open end of the other shell, at times, to produce a “WA-WA” rattling sound.
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:
