Claim 14:
15. A fluid dispenser comprising:
a fluid pump for dispensing fluid on movement of an actuator activated by a user;
a first sound generator which generates a first sound when the fluid dispenser is activated by the user, the first sound generator being configured to produce the first sound from a first stream of air passing through the first sound generator;
a second sound generator which generates a second sound when the fluid dispenser is activated by the user, the second sound generator being configured to produce the second sound from a second stream of air passing through the second sound generator; and
at least one air pump for passing the first stream of air through the first sound generator and the second stream of air through the second sound generator on movement of the actuator;
wherein in a cycle of operation to dispense a dose of the fluid, the actuator is moved between a first position and a second position;
wherein the first sound generator produces the first sound as the actuator is moved from the first position to the second position, and the second sound generator produces the second sound as the actuator is moved from the first position to the second position;
the fluid dispenser further comprising:
a fluid chamber containing the fluid to be dispensed; and
a fluid outlet in fluid communication with the fluid chamber, for dispensing the fluid from the fluid chamber;
wherein movement of the actuator from the first position to the second position pressurizes the fluid contained within the fluid chamber, forcing an allotment of the fluid to be expelled from the fluid outlet;
wherein the actuator resists movement from the first position to the second position as the pressure of the fluid contained within the fluid chamber increases;
wherein the fluid dispenser further comprises a resistance generator configured to increase the pressure of the fluid contained within the fluid chamber to provide resistance against movement of the actuator from the first position to the second position; and
wherein the resistance generator is configured to moderate fluctuations in a sound profile produced by the first sound generator and the second sound generator when the fluid dispenser is activated.
