Abstract

Акустические устройства, основанные на действии изгибной волны в панельном элементе, особенно на распределении резонансных режимов такого действия изгибной волны и связанных акустически существенных поверхностных колебаний по площади указанного панельного элемента, предпочтительных для требуемой или, по меньшей мере, приемлемой акустической характеристики устройства. Устройства соответствуют параметрам выбора указанного панельного элемента, влияющим на указанное распределение, включающим в себя конфигурацию/геометрию и/или изгибную жесткость(и) и/или местоположение(я) преобразователя(ей) изгибных волн в указанной области указанного панельного элемента, выбор осуществляют в соответствии с аналитической оценкой передачи мощности, относящейся к характеристике(ам) указанного панельного элемента, таким образом указанное соответствующее акустическое устройство и предметы для него соотносятся с достижением характеристик указанного акустического устройства.Международная заявка была опубликована вместе с отчетом о международном поиске.
