Abstract

Излучатель звука имеет зонально распределенную решетку многочисленных акустических преобразователей, имеющих индивидуальные средства возбуждения. Можно использовать большое количество преобразователей, и они могут быть преобразователями любого типа. Сигналы возбуждения создают излучения звука со сдвигами фаз из преобразователей в распределениях по зоне решетки, имеющие требуемый рассеянный или, в частности, речевой характер. Средство для обеспечения сигналов возбуждения выполнено с возможностью фазового сдвига содержимого верхних акустических частот, а также дополнительно для синфазной работы, по меньшей мере, некоторых преобразователей в субзоне (субзонах) решетки для содержимого нижних частот.Международная заявка была опубликована вместе с отчетом о международном поиске.The sound emitter has a zoned distributed array of numerous acoustic transducers with individual excitation means. A large number of transducers can be used, and they can be transducers of any type. The excitation signals produce sound radiation with phase shifts from the transducers in the distributions over the lattice area, having the required diffuse or, in particular, speech character. The means for providing the excitation signals is adapted to phase shift the contents of the upper acoustic frequencies, and also additionally for the in-phase operation of at least some transducers in the subband (subzones) of the trellis for the contents of the lower frequencies. The international application was published together with an international search report.
