Abstract

PURPOSE:To make flat the output audio pressure frequency characteristics, by providing the front chamber formed with plane including the dome shape oscillation plate and the frame front surface and the bobbin inner circumferential plane. CONSTITUTION:The dome oscillation plate 8 is bonded inside the bobbin 6 so that the front chamber 10 can be formed with the plane including the front plane of the frame 1 and the internal circumferential plane of the bobbin 6. Further, it is bonded at the inner circumferential plane of the bobbin 6 with the adhesives 9 so that the top 11 of the oscillation plate 8 is projected from the plane including the front plane of the frame 1. Further, the output sound pressure characteristics can be made flat by masking equal the volume of the front chamber 10 and the projected part 11.
