Abstract

En aktiv akustisk anordning omfatter en paneldel (11) med en fordeling av resonansmodi av bøyningsbølgevirkning som bestemmer akustisk ytelse i forbindelse med en transduseranordning (31-34). Transduseranordningen (31-34) er koplet til panel- delen (11) i en marginal posisjon. Arrangementet er slik at det resulterer i akustisk akseptabel virkning avhengig av den nevnte fordeling av aktive resonansmodi. Metoder for utvelgelse av transduser- plasseringen, eller forbedring ved plassering av lokali- sert marginal fastspenning, er basert på bedømmelse av den beste eller en bedre operativ vekselvirkning av transduseranordningen (31-34) og paneldelen (11) i henhold til parametere av akustisk ytelse for anordningen som en akustisk radiator.An active acoustic device comprises a panel portion (11) having a distribution of resonant modes of bending wave action which determines the acoustic performance of a transducer device (31-34). The transducer device (31-34) is connected to the panel portion (11) in a marginal position. The arrangement is such that it results in acoustically acceptable effect depending on the aforementioned distribution of active resonant modes. Methods for selecting the transducer location, or improving upon placement of localized marginal clamping, are based on the assessment of the best or better operational interaction of the transducer device (31-34) and the panel portion (11) according to parameters of acoustic performance. for the device as an acoustic radiator.
