Abstract

See full text

The present invention provides a speaker system comprising: an electroacoustic converter film composed of a polymeric composite piezoelectric body in which piezoelectric body particles are dispersed in a viscoelastic matrix formed of a polymer material that exhibits viscoelasticity at normal temperature, and thin film electrodes formed on both surfaces of the polymeric composite piezoelectric body; and a driving circuit that attenuates signal intensity of an input signal from a signal source at a rate of 5 dB to 7 dB per octave and supplies the attenuated input signal to the electroacoustic converter film.
