ON-VEHICLE ACOUSTIC REPRODUCTION SYSTEM

摘要

PURPOSE:To obtain the on-vehicle acoustic reproduction system in which hall simulation and sound field correction are executed by using a DSP and the sound quality of a source is maintained. CONSTITUTION:An output signal of a head unit 1 being a source is inputted to an A/D converter 2 and a DSP 3 and also inputted directly to a mixer 5a not through the A/D converter 2 and the DSP 3 and mixed with the signal with a reflecting sound and a reverberation sound added thereto through the DSP 3 at the mixer 5a. Then the resulting signal is amplified by a power amplifier 6a and the amplified signal is outputted from front speakers 7a, 7b. Thus, the source is reproduced while the sound quality is not deteriorated by the DSP 3 and the sound field is corrected by the DSP 3.
