The beneficial effect of the patent is: the protective cover is set at the speaker playback panel, so that when the speaker is not in use, the protective cover can reduce the accumulation of dust on the playback panel, especially at the speaker, so as to improve the playback effect of the Bluetooth speaker after long-term storage. At the same time, the protective cover can slide along the first slide on the side of the Bluetooth colorful speaker body. When the protective cover slides to the top, the speaker is shielded from sunlight or small raindrops when used outdoors, so as to prevent the speaker below from being directly affected by environmental factors, shortening the service life of the speaker or even damaging the speaker. The handle on the top of the speaker can fix the protective cover when it covers it to prevent it from shaking, thereby achieving a better protective effect.
