Abstract
PURPOSE:To eliminate distortion of a sound wave and to improve the frequency characteristics at a low voice band, by providing the thin film to shield the horn opening, and packing a gas heavier than air in a front space surrounded with a horn and thin film and a rear space of a diaphragm plate. CONSTITUTION:A thin film 10 evaporating Al on an Al thin film or polyvinylchloride and formed in film is given to an opening end of a horn 6 via a packing 9. A reflecting plate 11 is hinged to one end of a cabinet 7, the horn opening is covered with an arbitrary angle, and sound waves can be reflected to an arbitrary direction. A gas 12 heavier than air, e.g., xenon gas is filled in a front space surrounded with a diaphragm plate 4, a horn 6, and the thin film 10, a front space of the diaphragm plate 4, and an internal space of the cabinet 7 connected to the rear space. Thus, the frequency characteristics of low frequencies can be increased for a speaker with small diameter.
