PURPOSE:To realize low sound emphasizing passive radiator in a bass reflex speaker system. CONSTITUTION:A front side of a case 10 is provided with a speaker 20 and a bass reflex opening 40 and a diaphragm 50 is fitted to the bass reflex opening and the vibration of the diaphragm is converted into an electric signal by a mechanical-electro transducer 70. Then a capacitive impedance C is connected to an output terminal of the mechanical-electro transducer to increase substantially the mass of the diaphragm 50. |
