The invention provides a sound box equipment. The sound box equipment comprises sound box casing, a horn body mounted at an upper portion of the sound box casing, a terminal connected with the horn body, an echo hole arranged below the horn body and an echo tube arranged in the echo hole, wherein the wall portion of the sound box casing is internally provided with a chamber, and the chamber is internally filled with damping particles. According to the sound box equipment, the chamber of the sound box casing is internally filled with the damping particles to make the sound box equipment have an excellent vibration damping effect in a work process, moreover, the sound box casing further has proper damping effects, the inner surface of the sound box equipment requires no sound absorption vibration damping materials, and problems of vibration and sound field interference caused by the sound absorption vibration damping materials can be solved.
