Abstract
Выходное устройство диафрагменного источника звука включает устройство вывода звукового сигнала по меньшей мере один динамик громкоговорителя и по меньшей мере одну диафрагму. По меньшей мере, один динамик громкоговорителя расположен на любой стороне устройства вывода звукового сигнала. Динамик громкоговорителя может являться встроенным динамиком громкоговорителя. По меньшей мере одна диафрагма может быть расположена на любом одном или на нескольких участках внутренней стороны и внешней стороны устройства вывода звукового сигнала. При воспроизведении звука динамиком громкоговорителя устройства вывода звукового сигнала диафрагма, расположенная на устройстве вывода звукового сигнала, воспринимает вибрацию звука, в результате чего обеспечивается создание резонанса внутреннего пространства устройства вывода звукового сигнала. Таким образом, устройство вывода звукового сигнала обеспечивает создание более мягких полутонов и расширения диапазона.
