How it works
The shaker comprises of an electrodynamic motor, and a mobile mechanical part. The mechanical part is made up of a rigid piston, attached to a frame via a flexible suspension. A piece of rubber on the top of the vibrator creates an air seal.
The rigid piston is directly coupled (fixed, glued, screwed, etc.) to the target structure.
The shaker is then excited with an electrical signal from an amplifier.
When the a current flows through the coil, the induced force
(Laplace Force, see chapter 3 section 2) is then applied to a piston which transfers it to the target structure.
