摘要

The loudspeaker has permanent magnets arranged in a base, and a voice coil immersed in a central opening of the magnets, where the coil is connected with a voltage source and excited to oscillate when voltage is applied to the opening. An elastic central device (1) is arranged at a side of the coil, where the side is turned towards a voice coil carrier. The central device has a set of bars (4) with windings (4') lying in a plane parallel to the base, where an end of each bar is connected with the coil and another end of each bar is connected with a cage.
