I require a Helmholts sound chamber to be mathematically modeled given a min/max dimension (very restricted space) for a piezo bender. The candidate will need to select a suitable bender and provide the relevant dimensions of the chamber to give maximum SPL at approximately 1kHz. The chamber opening will be covered with a gauze material which needs to be accounted for in the calculations. Electronics to drive the bender must be designed and simulated (preferably SPICE) given a 3V supply and frequency/duty cycle controlled PWM output of a microcontroller. The type of drive circuit is left up to the candidate but the goal is to obtain maximum SPL while keeping the physical size and cost of the electronics to a minimum. All results must be presented and justified mathematically.

Hello. I have some questions: What shape resonator is preferable for you ( spherical , cylindrical, flat, as a cube or the other. )? Maximum or minimum size of resonator? Tube output channel can be moved inward or More
