Abstract

A találmány tárgya akusztikus eszköz, például hangszóró, amelyellentétes oldalakkal rendelkező rezonáns hajlítóhullámú akusztikuspanelt (5), a panel (5) egyik oldalának legalább egy részét lezáróüreget definiáló és a panel oldalának ezen részéről származóakusztikus sugárzás visszatartására kiképzett eszközt (2) tartalmaz.Az üreg elég sekély ahhoz, hogy az üregnek a panel (5) ezen oldalafelé eső hátsó oldala fluid csatolást okozzon a panelhez (5) olymódon, hogy a fluidumban a keresztező X és Y módusok általábandominánsok legyenek, továbbá úgy, hogy módosítsa a panel (5) modálisviselkedését. A találmány tárgya továbbá ilyen akusztikus eszközttartalmazó hangszóró, valamint eljárás hajlítóhullámú rezonáns panelttartalmazó akusztikus eszköz modális viselkedésének többszörözésére. ÓThe subject of the invention is an acoustic device, for example a speaker, which includes a resonant bending wave acoustic panel (5) with opposite sides, a device (2) defining a sealing cavity on at least one side of the panel (5) and designed to contain acoustic radiation from this part of the side of the panel. shallow enough that the rear side of the cavity towards this side of the panel (5) causes fluid coupling to the panel (5) in such a way that the intersecting X and Y modes in the fluid are generally dominant and also to modify the modal behavior of the panel (5). The subject of the invention is also a loudspeaker containing such an acoustic device, as well as a method for duplicating the modal behavior of an acoustic device containing a bending wave resonant panel.
