Speaker box with U-shaped bending channels

摘要

One embodiment of the invention discloses a speaker box having a housing and a speaker accommodated in the housing. The speaker includes a sound radiation surface for generating sound. The housing includes a first and second output ports disposed at one side of the housing for transmitting the sound to outside of the speaker box. The housing includes a plurality of ribs disposed therein and forming a bending channel. The first and second output ports are disposed at two ends of the bending channel. The bending channel is divided into a front channel and a back channel by the speaker. The speaker box is capable of obtaining a better low frequency sound reproduction quality.
