Abstract

PURPOSE:To increase the radiation efficiency of low tone band, by increasing the mutual radiation impedance produced between the diaphragm plate of a speaker unit and the mass provided separately. CONSTITUTION:A speaker unit 12 consists of the field 13, frame 14, edge fitting section 14a, voice coil bobbin 15, damper 16, dust cap 17, diaphragm plate 18, dron cone 20 of ring shape supported with edges 21, 22, and it is contained in the cabinet 11. With this constitution, since the diaphragm plate 18 and the dron cone 20 being the mass are located near, the mutual impedance between the both is very greater, the sound pressure characteristics at low tone band is improved and the radiation efficiency can be increased.
