Claim 2:
3. 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;, wherein the first sound generator produces the first sound during a first time period and the second sound generator produces the second sound during a second time period, the first time period being different than the second time period, the time period of each sound in the cycle of operation being a function of the relative location of the actuator between the first position and the second position;
wherein the at least one air pump delivers the first stream of air through the first sound generator during the first time period when the actuator moves from a first sound start position to a first sound end position; and
wherein the at least one air pump delivers the second stream of air through the second sound generator during the second time period when the actuator moves from a second sound start position to a second sound end position.
