Title: SOUND REPRODUCING DEVICE
Abstract:
The objective of the invention is to provide a sound reproducing device with which it is possible to eliminate the problem of insufficient low-frequency sound when reproducing sound with a low to medium volume, and with which it is possible to prevent a deterioration in the sound quality of the reproduced sound when reproducing sound with a high volume, even using a speaker unit having a relatively small aperture. This sound reproducing device (10) is provided with a DSP (12) and a microcomputer (11) which subject an input signal to prescribed computations, and an AMP (13) which amplifies the signal that has been subjected to the prescribed computations and outputs the signal to a speaker unit. Then, the DSP (12) and the microcomputer (11) cut a portion of the low frequency range of a frequency characteristic that is the reverse of the frequency characteristic of the speaker unit (4), and perform a computation to superimpose the resulting signal onto the input signal.
