description The utility model relates to a flat-panel sound box, comprising a support, a cover plate and a back plate are installed on the support, and the cover plate, the back plate and the support form a sealed cavity; the suspension device is installed on the support, and the suspension device is installed in the sealing cavity; an exciter is installed on the suspension device and abuts against the cover plate, and the cover plate is driven by the exciter to generate vibration; and the distance between the suspension device and the back plate is 2-5mm. The flat-panel sound box has the following beneficial effects: through the suspension device 400 arranged in a suspension manner, the suspension device 400 is prevented from colliding with the back plate 200, and the back plate 200 is prevented from directly participating in vibration, so that resonance is avoided, the sound effect of the flat-panel sound box is ensured not to be interfered, meanwhile, the thickness of the flat-panel sound box can be prevented from bei
