Abstract

PURPOSE:To reduce an adverse effect due to a non-motional impedance by defining an output impedance in the vicinity of a resonance frequency relating to a sound pressure in the actual using state of a converter to be negative and setting the output impedance of a band which cannot neglect an influence applied to a sound quality by the non-motional impedance to zero or positive. CONSTITUTION:At the time of driving an electro-acoustic converter, the converter is driven by the negative impedance R0 in the vicinity of the resonance frequency f0 relating to at least of the sound pressure of the resonance frequency f0 in the actual using state of this converter. In the band which cannot neglect the influence applied to the sound quality by the non-motional impedance of the converter, it is driven by the zero or positive impedance. Thereby, the adverse influence to the sound quality by said impedance by the non-motional impedance of the converter can be made equal to or lower than a general constant voltage driving system.
