Patent ID: 7581509

Claim:
A hybrid whistle having both a pealess chamber and a pea chamber, comprising: a mouthpiece with a left air opening, a central air opening and a right air opening; a left pealess whistle, comprising a left air passageway extending from the left air opening to a left air whistle chamber having a left air exit vent, wherein air flows from the left air opening through the left air passageway into the left air chamber and then exits the left air exit vent when the hybrid whistle is blown, thus creating a left whistle pitch sound; a right pealess whistle, comprising a right air passageway extending from the right air opening to a right air whistle chamber having a right air exit vent, wherein air flows from the right air opening through the right air passageway into the right air chamber and then exits the right air exit vent when the hybrid whistle is blown, thus creating a right whistle pitch sound; and a central pea whistle, comprising: a central whistle barrel chamber having a central exit vent, a pea block and a pea contained but movable within the central whistle chamber; and a central air passageway extending from the central air opening to the central whistle barrel chamber; wherein air flows from the central air opening through the central air passageway into the central whistle barrel chamber causing the pea to circulate within the central whistle barrel chamber and then exits the central air exit vent when the hybrid whistle is blown, thus creating a central whistle pitch sound; and wherein the pea block is formed within the central whistle barrel chamber so as to modify the barrel shape of the chamber and block air flow as the pea circulates in the air current causing a staccato effect while creating enough circulating air movement to prevent the pea from getting stuck in the vent by the air as it exits out of the central air exit when the whistle is blown; wherein the mouthpiece, the left pealess whistle, the right pealess whistle and the central pea whistle are integrally formed together with the central pea whistle being located between the left and the right pealess whistles; wherein the left air exit vent is substantially 180 degrees opposite the right air exit vent along a plane formed perpendicularly through the central air passageway, the left air passageway and the right air passageway; and wherein the central exit vent is substantially 90 degrees away from both the left air exit vent and the right air exit vent along the plane.
