Abstract
A loudspeaker comprises a chassis (1) having a front (Ia), a diaphragm (3) movably suspended from the chassis, and an electromagnetic driver (5) for driving the diaphragm with regard to the chassis. The driver includes a magnet system (7) connected to the chassis and a voice coil (9) connected to the diaphragm to cooperate with the magnet system via an air gap (11). In order to create sufficient cooling capacity at least one ventilation shaft (30) is provided which is connected to at least one ventilation hole (40) in the magnet system and which ends in or near the front of the chassis, wherein the at least one ventilation hole is in communication with the air gap.
