摘要： The present disclosure discloses an acoustic output apparatus. The acoustic output apparatus may include an acoustic driver. The acoustic driver may include a diaphragm and a magnetic circuit structure. A front side of the acoustic driver may be formed at a side of the diaphragm away from the magnetic circuit structure. A rear side of the acoustic driver may be formed at a side of the magnetic circuit structure away from the diaphragm. The diaphragm may vibrate to cause the acoustic driver to radiate sound outward from the front side and the rear side of the acoustic driver. The acoustic output apparatus may further include a housing structure configured to carry the acoustic driver. One side of the front side and the rear side of the acoustic driver may form a cavity with the housing structure. The side of the acoustic driver forming the cavity may radiate the sound towards the cavity, and the other side of the acoustic driver may radiate the sound towards outside of the acoustic output apparatus.
