Abstract

Акустический элемент панельного типа, способный выдерживать колебание изгибной волны, имеет скорость изгибной волны, изменяющуюся в области совпадения для получения диапазона частот совпадения, способствующего акустической связи изгибных волн в панели в более широком диапазоне углов или созданию более равномерной связи. Элемент может быть введен в громкоговоритель, имеющий панельный элемент (1) и возбудитель (3), прикрепленный к панельному элементу для возбуждения изгибных волн в громкоговорителе, чтобы получить акустический выходной сигнал.Международная заявка была опубликована вместе с отчетом о международном поиске.A panel-type acoustic element capable of withstanding a flexural wave oscillation has a flexural wave speed varying in the coincidence region to obtain a coincidence frequency range that contributes to acoustic coupling of flexural waves in a panel over a wider range of angles or creating a more uniform coupling. The element can be inserted into a loudspeaker having a panel element (1) and a pathogen (3) attached to a panel element for exciting bending waves in a loudspeaker in order to obtain an acoustic output signal. The international application has been published along with an international search report.
