Abstract
The present disclosure provides a speaker box which comprises a shell, a speaker, a support wall, and a sound guide channel. The speaker is fixed to be supported on the support wall. The diaphragm of the speaker partitions the receiving space into a front sound cavity and a rear cavity. The sound guide channel communicates the front sound cavity with the outside and forms the front cavity with the front sound cavity. The speaker box also comprises a surrounding wall and a cover plate arranged on the surrounding wall. The surrounding wall is located on the outside of the support wall, and the shell, surrounding wall, support wall and cover plate are jointly enclosed as auxiliary acoustic cavity. Compared with the related art, the high frequency acoustic performance of the speaker box of the present disclosure is excellent.
