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.The output device of the diaphragm sound source includes a sound output device for at least one loudspeaker speaker and at least one diaphragm. At least one loudspeaker speaker is located on either side of the audio output device. The loudspeaker speaker may be a built-in loudspeaker speaker. At least one diaphragm can be located on any one or several areas of the inner side and the outer side of the audio output device. When sound is reproduced by the speaker of the loudspeaker of the audio output device, the diaphragm located on the audio output device senses the vibration of the sound, as a result of which the internal space of the audio output device is created. Thus, the audio output device provides a softer halftones and range expansion.
