Abstract
A signal processing device includes: a resonant band-pass filter which extracts a frequency component which causes resonance of a housing from an input signal; a harmonic generating unit configured to generate a harmonic signal for an output signal of the resonant band-pass filter; an adding unit configured to add an output signal of the harmonic generating unit and at least a portion of a frequency component of the input signal; and a resonant band-stop filter which removes the frequency component which causes the resonance of the housing from an output signal of the adding unit.
