WHISTLE BALL
First Claim
Patent Images
1. A ball, comprising:
- (a) a body having an outer surface;
(b) a chamber disposed within the body, the chamber having a concave curvature in at least two orthogonal directions; and
(c) an aperture disposed in the body, the aperture defining a fluid connection between the chamber and the outer surface, wherein a flow of air across the aperture produces a whistling sound.

Abstract
A ball includes a body having an outer surface. A chamber is disposed within the body and has a concave curvature in at least two orthogonal directions. An aperture defines a fluid connection between the chamber and the outer surface of the ball. Air flow across the aperture produces a whistling sound.

12. A ball, comprising:
-
(a) a body having an outer surface; (b) a chamber disposed within the body, the chamber comprising; (i) a frusto-conical first portion; and (ii) a second portion having a concave curvature in at least two orthogonal directions; and (c) an aperture disposed in the body, the aperture being in fluid connection with the chamber and the outer surface, wherein a flow of air across the aperture produces a whistling sound. - View Dependent Claims (13, 14)

15. A ball, comprising:
-
(a) a body having an outer surface; (b) a first chamber disposed within the body, the first chamber having a concave curvature in at least two orthogonal directions; (c) a first aperture formed in the body, the first aperture defining a fluid connection between the first chamber and the outer surface, wherein a flow of air across the first aperture produces a first whistling sound; (d) a second chamber disposed within the body, the second chamber having a concave curvature in at least two orthogonal directions; and (e) a second aperture formed in the body, the second aperture defining a fluid connection between the second chamber and the outer surface, wherein a flow of air across the second aperture produces a second whistling sound. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of launching a ball using a launching apparatus to produce a whistling sound, the ball comprising one or more apertures producing a whistling sound when a flow of air passes over the one or more apertures, the method comprising:
-
(a) placing the ball into a holder disposed on the launching apparatus; and (b) moving the launching apparatus from a first position toward a second position, wherein momentum of the ball releases the ball from the holder when the launching apparatus is in the second position, the released ball moving along a trajectory that results in an airflow across the one or more apertures to produce a whistling sound. - View Dependent Claims (22, 23)
