Abstract
The present disclosure provides an acoustic output device including an acoustic driver, and a first cavity and a second cavity acoustically coupled to the acoustic driver. The first cavity and the second cavity are provided with a first acoustic hole and a second acoustic hole, respectively, from which the acoustic driver radiate sounds with a phase difference to an outside environment. Within a target frequency band, a near-field sound radiated from the first acoustic hole and a near-field sound radiated from the second acoustic hole may have a near-field sound pressure level difference of less than 6 dB, and the sound radiated by the acoustic output device to a far-field has directivity, which is manifested in that the sounds radiated from the two acoustic holes have a far-field sound pressure level difference of not less than 3 dB in at least one pair of opposite directions.
