[0002] Speakers refer to a device that can convert audio signals into sounds. Speakers are an indispensable and important component in smart voice devices, especially as digital speakers are becoming more and more widely used. Speakers usually include speakers and a shell arranged outside the speakers. The speakers can amplify the sound and play it to meet the needs of use. Existing speaker boxes generally have a sound opening, and the speakers are connected to the sound opening to discharge the sound through the sound opening. Dust covers are generally installed on the existing sound openings to prevent dust from entering the inside of the speaker box. However, a large amount of dust will accumulate on the dust cover after being used for a period of time, which will affect the sound effect. Therefore, the speaker box needs to be cleaned regularly during use, and the dust cover generally needs to be disassembled and cleaned, which makes the use more cumbersome. At the same time, when the speaker box is in use, the dust cover cannot be disassembled and cleaned, which affects the sound effect.
