摘要

The coil loudspeaker comprises a funnel and a loudspeaker chassis and fulfils the properties of an exponential horn. The funnel has only curved surfaces (1,2) with a material thickness capable of carrying the loudspeaker. Through its compact shape, it is stable and space-saving. The loudspeaker chassis (5) has a magnet fitted internally or externally and is conical. It is directly accessible from the exterior. Carrying devices are provided for the loudspeaker. The shape of the acoustic funnel surfaces is rectangular, trapezoidal or hexagonal.
