发明名称 Speaker control apparatus and speaker system
摘要 There is provided a speaker control apparatus capable of efficiently improving frequency characteristic of a speaker apparatus of phase inversion type, which is originally small in size and high in efficiency. The speaker control apparatus(10) includes a detection section(5) for detecting sound pressure within a speaker apparatus(1) of phase inversion type and generating a sound pressure signal Spo corresponding to the detected sound pressure, a signal processing section(13) for generating a feedback signal Sfb for feedback on the basis of the detected sound pressure signal Spo, a feedback section(11) for feeding back the feedback signal Sfb to an input signal corresponding to sound to be radiated and generating a feedback input signal Ssy, and an amplification section(12) for driving a speaker unit included in the speaker apparatus(1) on the basis of the feedback input signal Ssy and causing radiation of sound.
