MEDIUM PLAYING DEVICE HAVING BRAINWAVE PLAYING FUNCTION

摘要

PURPOSE: A medium playing device having a brainwave playing function is provided to fully play a brainwave signal through an exclusive speaker without increasing a voice signal in order to increase the brainwave signal by subtracting/adding only the brainwave signal depending on a deviation of each person. CONSTITUTION: A media player is equipped with a voice signal processor(140) and a voice amplifier(150) for playing a voice. A brainwave data storage stores the brain wave data generated from a human brain. A brainwave amplifier(170) amplifies the brainwave data. A synthesizer(180) synthesizes an output signal of the brainwave amplifier and the voice amplifier. A controller(200) makes the brainwave data storage apply one brainwave data to the brainwave amplifier by responding to the first control signal from the outside and controls an amplification yield by responding to the second control signal from the outside.
