Publication number: US20210384873A1
Application number: 17/408,871

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.

A sound generator includes a sound generating body, a base, a protection wall, and an erected wall. The sound generating body includes a diaphragm and a driving portion. The base includes a base tubular portion and a partition wall defining a sound hole. The diaphragm and the partition wall divide an inner space of the base tubular portion into a first space and a second space. The protection wall is disposed away from the partition wall and the erected wall connects between the protection wall and the base tubular portion. The protection wall, the erected wall, and the partition wall defines a sound emission space in communication with the first space through the sound hole. The protection wall and the erected wall define an emission hole through which the sound exits.
