GENERATING DYNAMIC PRESSURE WITH LOUDSPEAKERS
T. Lokar, A. Smrecnik, I. Bajsic
Abstract:
In this paper, the possibility for acquiring dynamic characteristics of pressure sensors is described. A dynamic pressure generator is assembled with two opposing loudspeakers and a confinement ring in-between. The ring has several openings for connection of the evaluated and reference pressure sensors. Frequency, waveform and amplitude control of the generated pressure were achieved by applying an amplified function generator signal to the loudspeakers. Since general-type audio loudspeakers were used, the solution is cost-effective as well. The background of our theoretical model, determination of the mechanical parameters, pressure measurements and arising problems that we found are shown.
