Title: Two tone whistle

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention is a whistle. More specifically, the present invention is a two-tone whistle. 
     Description of the Related Art 
     Comparable products on the market do not offer an effective way for referees and officials to be heard during athletic competitions, especially when multiple events are taking place in the same venue. Likewise, similar products in existence do not allow persons to alter the tone of the pitch in a given whistle, making it difficult to differentiate when officials are actually making a call on a play or if something entirely different is occurring at the time. 
     What is needed is a two-tone whistle that alters an audible pitch that reduces confusion when multiple athletic events are played with whistles being blown during the multiple athletic events. 
     SUMMARY OF THE INVENTION 
     The present invention is a whistle. More specifically, the present invention is a two-tone whistle. 
     The two-tone whistle includes a mouthpiece adapted to be blown into by a person to generate an audible pitch, a resonate chamber receiving air blown into the mouthpiece, a ball contained within a semi-circular portion of the resonate chamber, a toggle lever disposed on an exterior side portion of the resonate chamber, the toggle lever is adapted to control the audible pitch by moving the toggle lever up or down, a lanyard aperture receiving a lanyard that is adapted to insert the lanyard through the lanyard aperture and a slotted edge placed above the ball contained within the resonate chamber, the slotted edge is integral to the toggle lever, the slotted edge is adapted to move up as the toggle lever moves up and is adapted to move down as the toggle lever moves down, the audible pitch is produced by the ball that is adapted to vibrate within the semi-circular portion of the resonate chamber against the slotted edge from the received blown air. 
     It is an object of the present invention to provide a two-tone whistle that features a whistle made out of all durable, high-grade plastic that functions in all conditions and an easily adjustable switch for added durability, convenience and flexibility. 
     It is an object of the present invention to provide a two-tone whistle that has an incorporated lever on the back or side of the whistle that allows refereeing officials to have access to two distinct and noticeably louder tones when making calls in a matter of seconds, ensuring a seamless and hassle-free experience every time. 
     It is an object of the present invention to provide a two-tone whistle that reduces confusion when multiple athletic events are played with whistles being blown during the multiple athletic events.

     DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS 
     Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some of the described aspects. For purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the illustrative embodiments. However, it will be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well-known features are omitted or simplified in order not to obscure the illustrative embodiments. 
     Various operations will be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention however the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation. 
     The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment, however, it may. The terms “comprising”, “having” and “including” are synonymous, unless the context dictates otherwise. 
       FIG. 1A  illustrates a first side view of a two-tone whistle  100 , in accordance with one embodiment of the present invention. 
     The two-tone whistles  100  may include a mouthpiece  110 , a resonate chamber  120 , a ball  130 , a lever  140  and a lanyard aperture  150 . 
     The mouthpiece  110  may be adapted to be blown into by a person such as a referee or other suitable person to generate an audible pitch. The resonate chamber  120  may receive air blown into the mouthpiece  110 . The ball  130  may be contained within a semi-circular portion  120 A of the resonate chamber  120  and the audible pitch may be produced by the ball  130  adapted to vibrate within the semi-circular portion  120 A of the resonate chamber  120  from the received blown air. The ball  130  may be made of cork, synthetic cork or other suitable material. The lever  140  may be disposed on an exterior side portion  140 A of the resonate chamber  120 . The lever  140  may be a toggle lever  142  that may be adapted to control the audible pitch by moving the toggle lever  142  up or down. The lanyard aperture  150  may receive a lanyard (not shown) that may be adapted to insert the lanyard through the lanyard aperture  150 . 
     The two-tone whistle  100  may be made of plastic, metal or other suitable material. 
       FIG. 1B  illustrates a first cutaway side view of a two-tone whistle  100 , in accordance with one embodiment of the present invention. 
     The two-tone whistle  100  may include a slotted edge  160 . The slotted edge  160  may be integral to the toggle lever  142  and is adapted to move up as the toggle lever  142  moves up. The audible pitch may be produced by the ball  130  that may be adapted to vibrate within the semi-circular portion  120 A of the resonate chamber  120  against the slotted edge  160 . When the slotted edge  160  may be adapted to move up, the ball  130  travels further within the resonate chamber  120  and it produces a first audible pitch. 
       FIG. 1C  illustrates a second cutaway side view of a two-tone whistle  100 , in accordance with one embodiment of the present invention. 
     The slotted edge  160  may be integral to the toggle lever  142  and is adapted to move down as the toggle lever  142  moves down. When the slotted edge  160  may be adapted to move down, the ball  130  travels a shorter distance within the resonate chamber  120  and it produces a second audible pitch, wherein the first audible pitch is lower than the second audible pitch. The difference between the first audible pitch and the second audible pitch is distinguishable so that the two-tone whistle  100  reduces confusion when multiple athletic events are played with whistles being blown at the first audible pitch and the second audible pitch during the multiple athletic events. 
       FIG. 1D  illustrates a first side view of a two-tone pea less or ball less whistle  200 , in accordance with one embodiment of the present invention. 
     While the present invention has been related in terms of the foregoing embodiments those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention may be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
