Abstract

PURPOSE:To obtain flat sound pressure frequency characteristics, by adding the absorber to the oscillation system, matching the resonance frequency of the absorber to the resonance point of the oscillation system, and suppressing the distortion in the sound pressure frequency characteristics. CONSTITUTION:The substance 11 having the elasticity like coil spring is fitted to the center of the dust cap 10 of a cone type dynamic speaker, and the substance 12 having a mass is fitted to the lower end. When the resonance frequency f[=1/2pi (M2C2)<1/2>] determined with the compliance C2 of the substance 11 and the mass M2 of the substance 12 is matched to the minimum resonance frequency f0, the low band resonance can be suppressed, and when it is matched to a given resonance frequency high frequency f1 or more, the high band resonance can be suppressed at the frequency.
