The present invention relates to an electrostatic acoustic transducer using a fluidic dielectric substance and, more specifically, to an electrostatic acoustic transducer using a fluidic dielectric substance of a liquid state, a sol state, or a gel state to be driven in a low voltage. The electrostatic acoustic transducer using a fluidic dielectric substance according to the present invention is characterized by comprising a conductive diaphragm; a conductive electrode installed to face the diaphragm; a fluidic dielectric substance of a liquid state, a sol state, or a gel state, having the relative permittivity of at least 1.5 and interposed between the diaphragm and the electrode; and a voltage input unit providing an input voltage according to an audio signal, wherein the diaphragm vibrates according to the input voltage to generate a sound pressure. |
