Abstract
A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.
Claims20
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;
- and
- 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.
