Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of an inverter tube of a sound box according to an embodiment of the present utility model, where the inverter tube 10 of the sound box includes a first tube segment 11, a connecting tube segment 13 and a second tube segment 12 sequentially connected, the first tube segment 11, the connecting tube segment 13 and the second tube segment 12 are internally communicated, one side of a tube wall of the first tube segment 11 protrudes outwards to form a protrusion 14, and a deceleration cavity 141 is formed inside the protrusion 14 and is internally communicated with the first tube segment 11.
The interior of the first pipe section 11 is communicated with the interior of the second pipe section 12 through the connecting pipe section 13, so that gas can circulate in the phase inversion pipe 10 of the sound box, the phase inversion pipe 10 of the sound box sequentially connects the first pipe section 11, the connecting pipe section 13 and the second pipe section 12, and a bulge 14 of a speed reducing cavity 141 which is internally formed and communicated with the interior of the first pipe section 11 is outwards protruded on one side of the pipe wall of the first pipe section 11, so that the radial size of a partial area of an internal channel of the first pipe section 11 is increased, the air flow speed is reduced, the noise output is reduced, and the sound quality is improved.
Specifically, in the present embodiment, the inner diameter of the deceleration chamber 141 is gradually reduced from inside to outside, so that the side wall of the protrusion 14 forms a guide surface 142 connected to the pipe wall of the first pipe segment 11. Wherein, the protrusion 14 may have a table-like structure, and the deceleration chamber 141 may have a trapezoid-like cross section.
Specifically, in this embodiment, the end of the suspended end of the first pipe section 11 is connected to a fixing connection plate 15 along the circumferential direction thereof, and the fixing connection plate 15 is provided with a hole site 151 through which a connection screw passes.
