Abstract
One or more embodiments of the present disclosure provide an acoustic output device, comprising a housing; a first loudspeaker disposed in the housing, the first loudspeaker being acoustically coupled with a first hole portion and a second hole portion disposed on the housing, respectively, and the first loudspeaker being driven by a first electrical signal to output a first sound wave and a second sound wave having a phase difference through the first hole portion and the second hole portion, respectively; and a second loudspeaker disposed in the housing, the second loudspeaker being driven by a second electrical signal to output a third sound wave. In a target frequency range, the superposition of the first sound wave, the second sound wave, and the third sound wave generates a directional far-field radiation from the acoustic output device.
