A device used for generating mechanical vibrations which includes at least one partially elastic closed shaped frame, a coil affixed to a first edge of the closed shaped frame, and an array fixed to a second edge of the closed shaped frame, where the array includes one or more magnets, and the closed shaped frame is configured to restrain the array and coil into an optimal relative position to limit movement of at least one of the coil and the array to a predefined path, where the movement is resultant upon an alternating current being applied to the coil so as to induce mechanical movement between the array and the coil. |
