Abstract
En lydutstråler har en arealmessig fordelt oppstilling av flere akustiske transdusere som har individuelle drivanordninger. Et stort antall transdusere kan benyttes og kan være av hvilken som helst type. Drivsignaler frembringer faseforskjellige lydutstrålinger fra transduserne i fordelinger over arealet av oppstil- lingen som har ønsket diffus eller spesielt stemt natur. En drivsignalfrcmbringende anordning medfører fase- forskyvning av høyere akustisk frekvensinnhold, og er videre operativ for i-fase-virkning for i det minste noen av transduserne i et delområde eller delområder av oppstillingen for lavere frekvensinnhold.An audio emitter has an areaally distributed array of several acoustic transducers having individual drive devices. A large number of transducers can be used and can be of any type. Drive signals produce phase-different sound emissions from the transducers in distributions over the area of the array that have the desired diffuse or particularly tuned nature. A drive signal generating device results in phase shift of higher acoustic frequency content, and is further operative for in-phase effect for at least some of the transducers in a sub-region or sub-regions of the lower frequency content array.
