Abstract

Описан плоский громкоговоритель повышенного качества, предназначенный для использования в (бытовой) аудиотехнике, в котором исключена возможность возникновения паразитных звуков благодаря установке звуковой катушки с высокой точностью в зазор магнитной цепи. Мембрана разделена на основную (11) и вспомогательную (12); звуковая катушка (8) присоединена к внутренней окружной периферии основной мембраны (11), внутренний диаметр которой, по существу, идентичен диаметру зазора (5) магнитной цепи. В громкоговорителе звуковая катушка (8) установлена в правильное положение без наклона и эксцентриситет по отношению к зазору (5) магнитной цепи, устранены паразитные звуки и достигнут компромисс между конструкцией меньшей толщины и более высокой повторяемостью параметров при серийном производстве.Международная заявка была опубликована вместе с отчетом о международном поиске.
