The invention relates to a music playing device, in particular to an egg-shaped 360-degree playing sound box capable of being hung on a ceiling. The egg-shaped 360-degree playing sound box comprises an egg-shaped casing, and a sound box module and a power amplifier connected with the sound box module are installed in the casing. The sound box module comprises a horn, a connection chuck connected with the sound box module in clamping mode and corresponding to the horn is arranged in the casing, an arc face cone corresponding to the horn is arranged at the bottom of the connection chuck, and sound given out by the horn covers 360 degrees of the periphery. The sound box integrates the sound box module with a stress bass passive radiator effectively, enables music to cover the surrounding environment in full directions on one hand, and achieves the effect that the small-space small-size sound box can give out good bass on the other hand. The sound box achieves maximum utilization of effective space and optimum combination of sound in high frequency, medium frequency and low frequency, and enables played music to be good in tactile sense, true and clear.
