DIGITAL AMPLIFIER, THREE-VALUE SIGNAL OUTPUT METHOD, AND SPEAKER

摘要

Noise is reduced when three-value output is performed. In a digital amplifier 1, a three-value driver 18a associated with a positive electrode and a three-value driver 18b output three-value signals which are inverted to each other, and execute an output of three values on the basis of a differential output of the positive electrode and a negative electrode.
