By arranging the length direction of the inverter tube 3 parallel to the width direction of the shell 1, the length of the inverter tube 3 is not less than half of the width of the shell 1, so that the loss of sound waves in the air before the sound waves enter the inverter tube 3 is reduced, the inverter tube 3 has good bass sinkage, the low-frequency response is improved, the time of low-frequency attenuation is prolonged, and the sound equipment has better tone quality.

When the sound box provided by the disclosure is specifically used, the edge of the protective net main body 21 is bent to form the first connecting piece 221 and the second connecting piece 222, colloid is arranged on the second connecting piece 222, one surface of the protective net 2, which is provided with the connecting part 22, is inserted into the mounting groove 11, the first connecting piece 221 and the second connecting piece 222 are positioned in the mounting groove 11, the second connecting piece 222 is bonded at the groove bottom of the mounting groove 11 through colloid, when the sound box works, sound waves played by the loudspeaker are transmitted to the outside of the shell 1 through the through hole at the groove bottom of the mounting groove 11, and meanwhile, the sound waves are transmitted to the outside of the shell 1 through the phase inversion pipe 3, vibration generated by the shell 1 is firstly transmitted to the colloid during the sound box works, and then the vibration generated by the protective net main body 21 is transmitted to the protective net through the second connecting piece 222 and the first connecting piece 221, so that resonance noise generated by the protective net main body 21 is avoided, and sound with high sound quality is played.
