Abstract

Акустическое устройство, содержащее элемент, который использует действие изгибных волн, с их полезным распределением резонансных мод в нем, в котором элемент имеет свою акустически активную область, по меньшей мере, частично ограниченную с помощью средства, обладающего, по существу, ограничивающим свойством относительно колебаний изгибных волн. Активное акустическое устройство, дополнительно имеющее выгодное местоположение средства преобразователя изгибных волн, определенное относительно и с учетом такого ограничивающего средства, может работать ниже частоты совпадения или выше, если это необходимо.Международная заявка была опубликована вместе с отчетом о международном поиске.An acoustic device containing an element that uses the action of bending waves, with their useful distribution of resonant modes in it, in which the element has its acoustically active region that is at least partially limited by means of having essentially a limiting property with respect to bending vibration waves. An active acoustic device, additionally having the advantageous location of the flexural wave transducer determined relative to and taking into account such limiting means, can work below the coincidence frequency or higher if necessary. The international application was published together with the international search report.
