PURPOSE:To eliminate the need for a damper and to achieve a speaker with no distortion, high efficiency and excellent sound quality, by providing a support pillar freely inserted to an axial supporter fitted with a diaphragm plate and providing a pipe jetting air in the pillar. CONSTITUTION:An axial supporter 2 is fixed to a diaphragm plate 1, a voice coil 3 is provided, a support pillar 5 freely inserted to the axial supporter 2 is implanted corresponding to a magnet 4 driving the diaphragm plate 1, and this is inserted to the axial supporter 2. Air is given to a hole 6 through the pillar 5 with a pipe 7 and the air is jetted at the inside of the axial supporter, allowing to float the supporter 2 and the diaphragm plate 1 from the pillar 5. A signal is inputted to the voice coil 3 and vibration is given while the diaphragm plate 1 is floated. Thus, any damper is made unnecessary, and a speaker without vibration distortion and stable and with excellent sound quality and high efficiency can be achieved. |
