Abstract: Disclosed herein are an audio apparatus and method for inducing a brainwave using a binaural beat, including a frequency shift unit for receiving a first audio sound source signal and generating a second audio sound source signal by shifting some of the frequency band of the first audio sound source signal by a specific frequency, and an audio output unit connected to the frequency shift unit, for outputting first and second audio output signals corresponding to the first and the second audio sound source signals. Accordingly, a user can hear a music signal or an audio signal for learning without being aware of the distortion of a sound source and can change his or her brainwave state without resistance or monotonousness because a required brainwave state is changed by applying a binaural beat to a specific frequency band of an audio signal, in particular, a music signal.

Abstract: The present invention relates to amplifier combined digital amplifier using pulse width modulation and analog amplifier, and more particularly, to amplifier converting the analog input signal to pulse width modulation signal by comparing the analog input signal with triangle-wave, inputting the pulse width modulation signal to a dead time logic circuit, controlling the “ON”, and “OFF” operation of output transistor by output signal of the dead time logic circuit and converting the pulse width modulation signal of the output transistor to amplified analog signal using LC low pass filter. The present invention reduces the loss of efficiency of output transistor. Therefore the size of heat radiating plate can be easily reduced and amplifier with compact size can be accomplished by the present invention.
