may be used to impart vibrational motion to the crib in response to audio signals ie music sent to wireless receiver 840 by a smart device ie smartphone or tablet computer amplified by amplifier 810 and driven through electromagnetic assembly 800 due to the extremely low profile design of transducer 805 it is possible that only one leg of a crib may be configured with transducer 805 without the need for other legs of the crib to be raised to level it will be understood and appreciated by those skilled in the art that a variety of compact amplifier and wireless receiver elements may be implemented with the current invention depending on the particular size and application of the transducer device without departing from the spirit and scope of the current invention turning now to fig9 through 11 an embodiment for configuration of dual axis theater seat assembly 900 is shown fig1 illustrates one side of the dual axis theater assembly 900 shown in fig9 and fig1 is an exploded view of fig1 according to the present embodiment two transducer 122 assemblies are arranged such that the axes of hinges 385 are in line with front axis of theater seat 100 generally.
