Deformable Bluetooth sound box

The invention provides a deformable Bluetooth sound box, and relates to the technical field of Bluetooth sound boxes. The installation supporting part is fixedly connected with a protection device. The interior of the mounting supporting part is fixedly connected with a moving control piece; four deformation mounting parts are rotationally connected to the mounting supporting part, four adaptive protection parts are fixedly connected among the four deformation mounting parts, and a Bluetooth loudspeaker box part is fixedly connected to the four adaptive protection parts; the four deformation mounting parts are respectively attached to the moving control piece; on one hand, the overall protection effect is better, the outdoor sound equipment is prevented from being easily collided and damaged, the dustproof effect is affected, and the sound quality is reduced, and deformation can be assisted to enhance the sound field effect. The problems that an existing deformable Bluetooth sound box is not provided with an
