Abstract
Akustični uređaji imaju ploče (20B) koje se šire poprečno na debljinu i koje su sposobne da prime longitudinalne talase, izazivajući kao posledicu akustično delovanje pomoću površinske raspodele prirodnih oscilacija longitudinalnih talasa u rezonantnom režimu, saglasno zahtevanom i ostvarivom akusstičnom delovanju ploče (20B) u željenom operativnom opsegu akustičnih frekvencija. Površinska raspodela krutosti uključujući i njeno variranje (variranja) koristi se za dobijanje željenog položaja pretvarača (25, 26) longitudinalnih talasa i/ili dobrog rezonantnog akustičnog delovanja od ovih, suštinski nepogodnih oblika ploče (20B). Ploče sa kombinovanim klipnim delovanjem i pobuđivanjem longitudinalnih talasa u težištu i geometrijskom centru (25) su određene.[Acoustic devices have members extending transversely of thickness and capable of sustaining bending waves causing consequential acoustic action by reason of areal distribution of resonant modes of natural bending wave vibration consonant with required achievable acoustic action of said member over a desired operative acoustic frequency range. Areal distribution of stiffness including variation(s) therein is used to get desired locations for bending wave transducers and/or good resonant mode acoustic action from inherently unfavourable shapes of members. Members with combined pistonic action drive and bending wave excitement at centres of mass and geometry are featured.
