Abstract

Aktivni akustični uređaj sastoji se iz membrane (11) koja ima raspodelu rezonantnih modova delovanja savojnih talasa, koji određuju akustične performanse zajedno sa pretvaračima (31-34). Pretvarači (31-34) su spojeni za membranu (11) na marginalnim pozicijama. Postavljanje se vrši tako da rezultira prihvatljivim akustičnim delovanje, zavisno od navedene raspodele navedenih aktivnih rezonantnih modova. Metode izbora položaja pretvarača ili metode poboljšavanja položaja lokalizovanog marginalnog spajanja, odnose se na preporuku najbolje ili bolje međusobne interakcije navedenih pretvarača (31-34) i membrane (11) na osnovu parametara akustičkog izlaza uređaja, kao akustičnog izvora.[Active acoustic device comprises a panel member (11) having distribution of resonant modes of bending wave action determining acoustic performance in conjunction with transducer means (31-34). The transducer means (31-34) is coupled to the panel member (11) at a marginal position. The arrangement is such as to result in acoustically acceptable action dependent on said distribution of active said resonant modes. Methods of selecting the transducer location, or improvement by location of localised marginal clamping, rely on assessing best or better operative interaction of said transducer means (31-34) and the panel members (11) according to parameters of acoustic output for the device as an acoustic radiator.
