Abstract

Громкоговоритель (81), содержащий корпус, звукоизлучающую панель (2) в корпусе, податливую подвеску (3), закрепляющую панель в корпусе для поршневого перемещения относительно него, и преобразователь (9) для поршневого возбуждения излучателя, отличающийся тем, что звукоизлучающая панель представляет собой звуковой излучатель с распределёнными режимами, выполненный в виде панели, первый преобразователь установлен полностью и исключительно на звукоизлучающей панели для возбуждения излучателя, чтобы вызвать его резонанс, а также отличающийся генератором накачки низких частот (11) для изменения давления воздуха в корпусе для обеспечения поршневого перемещения излучателя.Международная заявка была опубликована вместе с отчетом о международном поиске.
