ABSTRACT:
An enclosure (35) of a loudspeaker (37) is provided with a plurality of tubes (43) of different length via which the sound is emitted in order to achieve frequency spreading of resonance peaks in the SPL (sound pressure level) curve. The side walls (46, 47) of the tubes (43) have openings (63) via which the tubes are coupled to common Helmholtz resonators (59, 61) in order to suppress undesirable resonances in the tubes (43). By spreading the resonance peaks it is possible to use Helmholtz resonators of smaller dimensions than in the case that the sound would emanate via a single tube. This results in a loudspeaker system (33) with more compact and cheaper Helmholtz resonators (59, 61).
