Description

Loudspeaker funnel

.—. Η

Lie invention "relates to triohter for pressure chamber ■ * · * loudspeaker, it consists in the fact that the funnel consists of: three parts placed on top of each other in such a way that the enclosed cross-section with the τ? ν!: .. ■> 3 am en ^ r; vf;? ^ nu.ng increases from the pressure chamber and that the second partial triohter deq the first partial triohter _s and the third partial triohter overlap the second in a cap-like manner so that the Cross-section of the sound wave front at the transition points from one partial funnel to the next is preserved

In this way, the funnel length is significantly shortened while the volume remains almost the same achievedi,

An exemplary embodiment of the invention is described in the following and shown in the drawing;
