Abstract
Abstract A hollow, open ended tube of flexible, semirigid material which has internally projecting ridges that are so shaped and positioned as to produce a musical tone when air flow is induced through the tube by holding it at one end and swinging the other end around in a generally circular path to create a pressure differential between the two ends of the tube or by mounting the tube on the exterior of a vehicle in line with the relative airstream when the vehicle is in motion. The tube may be attached at one end to a hollow, extensible, spring-loaded handle.

Total Claims: 4
Claim 1
Independent Claim
100 words
A tone generator comprising a hollow tube which is open a both ends, a plurality of spaced, inwardly projecting ridges within the hollow interior of said tube, said ridges being shaped and positioned to produce a musical tone in response to the passage of an air stream through said tube, said tube being comprised of a flexible, semirigid material which is capable of being resonated at audible frequencies and sufficiently flexible to be grasped at one end and swung about the head of a user, and further comprising a hollow spring-loaded extensible handle attached to one end of said tube.
Claim 2
Dependent Claim
100 words
A tone generator comprising a hollow tube which is open a both ends, a plurality of spaced, inwardly projecting ridges within the hollow interior of said tube, said ridges being shaped and positioned to produce a musical tone in response to the passage of an air stream through said tube, said tube being comprised of a flexible, semirigid material which is capable of being resonated at audible frequencies and sufficiently flexible to be grasped at one end and swung about the head of a user, and further comprising a hollow spring-loaded extensible handle attached to one end of said tube.
Claim 3
Dependent Claim
121 words
A tone generator comprising a hollow tube which is open at both ends, a plurality of spaced, inwardly projecting ridges within the hollow interior of said tube, said ridges being shaped and positioned to produce a musical tone in response to the passage of an air stream through said tube, said tube being comprised of a flexible, semiridig material which is capable of being resonated at audible frequencies, said tube being made of polyethylene plastic having a wall thickness of approximately 1/32 inch, an inside diameter of approximately 11/8inches, and a length of approximately 36 inches, and wherein the height of said inwardly projecting ridges is approximately 3/16 inch and the spacing between said inwardly projecting ridges is approximately 1/4 inch.
