Abstract

Громкоговоритель содержит корпус, снабженный магнитным блоком, создающим магнитное поле, и мембраной, которая установлена в рамке и снабжена электрическим проводником, расположенным на мембране в виде рисунка, при этом мембрана помещена в магнитное поле так, что когда через проводящий рисунок пропускают ток, на мембрану действует сила, способная приводить ее в движение, чтобы создавать звук, причем проводящий рисунок сформирован на мембране по меньшей мере в двух пространственно разнесенных вибрирующих областях, а громкоговоритель снабжен по меньшей мере двумя звуковыми каналами, проходящими между двумя вибрирующими областями и внешней стороной корпуса, и центральные оси этих двух звуковых каналов, расположенные между внешней и внутренней стенкой каждого канала, наклонены друг к другу на определенном расстоянии от мембраны.Международная заявка была опубликована вместе с отчетом о международном поиске.
