Claim 5:
6. The fluid dispenser according to claim 5, wherein the sealing body is configured to unseal the air passage during an intermediate time period in which the actuator moves from the first sound start position to the second sound start position;
wherein the actuator is configured to reduce a volume of air contained within the first air chamber forming body during movement from the first position to the second position, forcing at least some of the air to discharge from the first air chamber forming body through the first sound generator as the first stream of air;
wherein the actuator is also configured to reduce a volume of air contained within the second air chamber forming body during movement from the first position to the second position, forcing at least some of the air to discharge from the second air chamber forming body;
wherein during the second time period the air is discharged from the second air chamber forming body through the second sound generator as the second air stream;
wherein during the intermediate time period at least some of the air is discharged from the second air chamber forming body through the air passage, thereby reducing or eliminating air flow through the second sound generator and causing the second sound generator to produce little or no sound during the intermediate time period;
wherein the actuator comprises a piston body; and
wherein movement of the actuator from the first position to the second position comprises an instroke movement of the piston body within the first air chamber forming body and the second air chamber forming body, thereby pressurizing the air contained within the first air chamber forming body and the second air chamber forming body and forcing at least some of the air to discharge from the first air chamber forming body and the second air chamber forming body.
