摘要

The loud speaker (100A) comprises a pipe element (102), which is controlled based on an acoustic signal, where the signal is created in a sound box. The sound box is arranged on an axis such as the pipe element, where a sound wave, is emitted from the sound box, which is radiated from the opposite ends of the pipe element. An independent claim is also included for a method for acoustic sound emission by emitting a sound wave from a sound box.
