Title:
SOUND SOURCE PROCESSING APPARATUS USING MAGNETIC DRUM
Document Type and Number:
WIPO Patent Application WO/2023/022241
Kind Code:
A1
Abstract:
The present invention relates to a sound source processing apparatus using a magnetic drum, the apparatus using the magnetic drum to prevent sound quality deterioration and amplify the volume of sound when a sound source transmitted from a primary acoustic device is outputted, and thus promote enhanced sound quality, and receiving, through an input end thereof, a sound source outputted from the primary acoustic device through a sound source input end, recording the inputted sound source on a recording part (a magnetic coating surface) of the magnetic drum in a magnetic drum recorder, reproducing, in real time, the sound source recorded on the magnetic drum, and then amplifying same, sequentially passing the amplified sound source through a pre-amplifier and a power amplifier to amplify output and send same to a speaker, to thus prevent deformation even for repetitive playback so that sound quality deterioration can be prevented, removing interaction caused by contact between sound sources so as to prevent sound quality deterioration, and amplifying the volume of sound outputted in real time by means of the magnetic drum, thereby enabling enhanced sound quality to be promoted.
