    摘要： In a sound reproducing apparatus, part of a frequency band where mode-coupled vibration can be excited is regarded as a carrier frequency. A frequency of mode coupling, with a low rate of change in vibration displacement with respect to the frequency, is regarded as a carrier signal so that a signal in an audible band which is outputted from an audible band signal source can be demodulated and reproduced with stable sound pressure in a broad frequency band.

    摘要： A sound reproduction apparatus reproduces a sound wave at a listening position. The sound reproduction apparatus includes a compensation processing unit for compensating an audible band signal having an audible band frequency, a carrier signal oscillator for generating a carrier signal, a modulator for outputting a modulated signal obtained by modulating the carrier signal based on the audible band signal compensated by the compensation processing unit, and a sound emission unit for outputting a sound wave depending on the modulated signal output from the modulator. The compensation processing unit compensates the audible band signal based on a distance from the sound emission unit to the listening position. This sound reproduction apparatus can reproduce the original audible band signal with a high fidelity regardless of the listening position.
