First it is loudspeaker, secondary loudspeaker’s baffle board. For loudspeaker ARA 390 00/8 the project of subwoofer was done in terms of TS parameters by using computational simulation for resonance frequency 40 Hz of bassreflex. In ANSYS program corresponding model of sound reproducer, bassreflex cabinet and surrounded air volume was done. The transient analysis was computed. The oscillation of loudspeaker membrane by constant amplitude and frequency was simulated. Implementation of fluidstructure interface allowed the structural vibration transformation to acoustic pressure in the air. The acoustic wave spread in the internal air volume and vibrate by sides. Thus the secondary resonators occurred on surrounding surfaces. 000001602 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000001602 653__ $$a 000001602 7112_ $$aEngineering Mechanics 2007$$cSvratka (CZ)$$d2007-05-14 / 2007-05-17$$gEM2007 000001602 720__ $$aDániel, V.$$iKošúth, S. 000001602 8560_ $$ffischerc@itam.cas.cz 000001602 8564_ $$s1831274$$uhttps://invenio.itam.cas.cz/record/1602/files/017-Daniel-PT.pdf$$y Original version of the author's contribution as presented on CD, . 000001602 962__ $$r1585 000001602 980__ $$aPAPER
