description An innovative magnetic design for speakers is disclosed. The innovative magnetic design of the present invention comprises an upper magnetic portion, a lower magnetic portion, at least one magnetic piece and two or more magnets. Either the upper magnetic portion or the lower magnetic portion has the form of a plate. A magnet is disposed between the upper magnetic portion and the magnetic piece, and another magnet is disposed between the lower magnetic portion and the magnetic piece. When an AC current flows through the voice coil, a magnetic force induced by the current would move the voice coil and diaphragm longitudinally, thereby generating audible sounds. In addition, we only have to increase the length of magnets 4 to increase their volume so as to increase the magnetic force and hence offset the decrease in the magnetic force due to a thinner configuration.
