The utility model provides an existing defect among the background art, have following beneficial effect:

the utility model provides a bluetooth sound lamp simple structure is reasonable, has solved the uneven problem that runs off with the easy outer expansion of sound of current bluetooth sound lamp sound, improves the tone quality and the audio of bluetooth sound lamp. The utility model discloses a built-in speaker of 4 equipartitions, can 360 degrees to sound all around. At the moment, the music is spread without directivity, the limitation of the position of a user is avoided, uniform sound can be obtained at any time, and the stereo perception of the sound of the Bluetooth sound lamp is improved. Set up the sound absorbing layer, carry out the sound absorption through the porosity of its material, can reduce the outer loss that expands of sound for sound can be in the inside reverberation of bluetooth sound, improves tone quality and the audio that the bluetooth sent, and user experience feels good. The structure of the radiating fins increases the speed of heat dissipation, optimizes the radiating effect and prolongs the service life of the Bluetooth sound lamp.
