Description:

This puzzle's objective is to release the central frame that surrounds the cross. At first sight it is impossible as there aren't apparently no movable pieces. In order to find them we need to use our sense of hearing ―if we shake slightly the puzzle we can hear a sound in the inside that provides an essential clue to solve the puzzle.
