1. An air inhalation device for delivering medicament to a user, said device comprising:
- an acoustic controller, said acoustic controller including an acoustic sensing element configured to detect air flow around said acoustic sensing element and to produce signals that identify the direction and amplitude of said air flow; and
a high frequency vibrator configured for inducing said medicament into said air flow when said signals indicate inhalation by said user.

Abstract
An fluid sensor to activate and control various components of an inhalation device. The fluid sensor includes an acoustic element, such as a microphone, positioned within said inhalation device to detect fluid within the device and output signals representative of the frequency, direction and/or amplitude of the fluid. These signals control and activate an electrostatic plate and/or a high frequency vibrator.
