Abstract: A dock with a sound box, comprises: an upper shell (1) having a loudspeaker hole (41) and an inverter tube hole (53) formed thereon; a lower shell (2) engaged with the upper shell to define a sound cavity (9); a loudspeaker (4) disposed in the sound cavity and coupled to the loudspeaker hole; an inverter tube (5) configured to boost a sound; and a closed box (6) defining an interior cavity therein. The inverter tube comprises a first tube segment (51) and a second tube segment (52), wherein, the second tube segment is bent and extended to the upper shell to couple with the inverter tube hole. The interior cavity is divided into a first chamber (61) and a second chamber (62) by a baffle plate (7). The first chamber and the second chamber are communicated with each other via a communication pipe (8) penetrating through the baffle plate.
