Abstract

Динамик в виде панели, имеющий источник (2) распределённого акустического излучения и преобразователь (9), непосредственно соединённый с ним для того, чтобы вызвать вибрацию источника излучения и заставить его резонировать, отличающийся вторым преобразователем (63), непосредственно соединённым с источником излучения, чтобы вырабатывать сигнал под воздействием резонанса источника излучения вследствие распространяющейся акустической энергии.Международная заявка была опубликована вместе с отчетом о международном поиске.
