    摘要: To avoid degradation of the acoustic signal radiated from the opening of the ducted horn of a ducted horn type speaker, under influence of the ducted horn, below the characteristic of the speaker itself, and input terminal for receiving an audio signal, a non-recursive digital filter for varying the input audio signal, a power amplifier for amplifying the varied signal, and speaker for replaying the amplified signal are provided. The non-recursive digital filter realizes the inverse characteristic of the transfer characteristic of the ducted horn.
