Abstract: The present disclosure provides a speaker box which comprises a shell, a support wall, a sound guiding channel, a surrounding wall and a cover plate. The speaker is fixed to support the support wall. The diaphragm of the speaker partitions the receiving space into a front sound cavity and a rear cavity, the sound guiding channel communicates the front sound cavity with the outside and forms a front cavity together with the front sound cavity, the shell, the surrounding wall, the support wall and the cover plate are jointly enclosed as an auxiliary acoustic cavity. The support wall is provided with at least two through-holes intervals, and the auxiliary acoustic cavity is communicated with the front cavity through the through-hole to form a resonant cavity structure of the front cavity. Compared with the related art, the high frequency acoustic performance of the speaker box of the present disclosure is excellent.

Abstract: The present disclosure provides a speaker box including a shell, a speaker box, a support wall formed by the inner extension of the shell, and a sound guide channel formed in the receiving space. The speaker is fixed to the support wall. The speaker box includes a surrounding wall formed by the inner extension of the shell and a cover plate arranged on the surrounding wall. The shell, surrounding wall, support wall and cover plate are jointly enclosed as auxiliary sound cavity. The support wall is provided with a through-hole, and the auxiliary sound cavity is communicated with the front cavity through the through-hole to form the resonant cavity structure. The speaker box further includes a leakage to achieve the sound pressure balance inside and outside of the shell. Compared with the related art, the high frequency acoustic performance of the speaker box of the present disclosure is excellent.

Abstract: A plug connector includes an insulating body, a first plug conductive terminal set and a second plug conductive terminal set. The insulating body includes a base portion, a tongue plate, at least two projections and a stopper block. The tongue plate extends onward from the base portion, the at least two projections extend from two sidewalls of the tongue plate, and the stopper block is positioned on an inner side of one of the at least two projections. The first plug conductive terminal set is fixed upon one side of the tongue plate. The second plug conductive terminal set is fixed upon the other side of the tongue plate.
