An audio output device includes PWM output devices, a weighting unit, a mixer, and an amplifier. The PWM output devices divide audio data into multiple parts including an upper bit part to a lower bit part, and output the multiple parts of the audio data as PWM outputs. The weighting unit weights the PWM outputs from the PWM output devices. The mixer synthesizes the PWM outputs after being weighted. The amplifier supplies an electric current to a sounding body in accordance with a synthesis result by the mixer to cause the sounding body to emit a sound.
