Abstract

The present invention provides a speaker sound box structure with high airflow efficiency, which comprises a hollow shell and a cover; wherein a front side of the hollow shell forms an opening, and two opposite sidewalls of the hollow shell are extended backwardly to a back sidewall from the opening rim in a wave-like and converged shape, and the other two opposite sidewalls are backwardly extended from the opening rim to the back sidewall in parallel. The back sidewall has the wall that shrinks backwardly. The cover is sized to fix to the opening rim, and is provided with a bass speaker and a base reflection hole therein. When the membrane of the base speaker vibrates, the air inside the hollow shell is smoothly guided and converged to the position on the inner side of the back sidewall corresponding to the bass reflection hole sequentially through the two opposite sidewalls with the wave-like design and the back sidewall in a backwardly converging design, and being emitted outwardly through the base reflection hole. Thus, the present invention can not only greatly reduce the negative impact on the membrane vibration caused by the compressed air in the hollow shell or the negative pressure effect, but also effectively improve the base quality and volume of the base speaker.
