Problems solved by technology
[0002] Due to the long-term placement of existing speakers, dust is prone to accumulate on the metal mesh of the speaker, which affects the sound of the speaker. Since the speaker is an electronic device, it is inconvenient to clean the dust with water. In the long run, it will inevitably affect the sound of the speaker. Cause an impact and affect the use of speakers

The invention discloses a dustproof loudspeaker box. The dustproof loudspeaker box comprises an upper cover part and a lower cover part which are connected through a plurality of telescopic rods and are in a cylindrical shape; and the lower cover part is provided with a loudspeaker, a vibrating diaphragm of the loudspeaker is located in the middle of the upper side face of the lower cover part andfaces the lower side face of the upper cover part, the diameter of the lower side face of the upper cover part is larger than the diameter of the vibrating diaphragm of the loudspeaker, and the telescopic rods are distributed at the periphery of the vibrating diaphragm of the loudspeaker. According to the loudspeaker box with the structure, due to the fact that the upper cover part is located over the vibrating diaphragm of the loudspeaker, dust can be prevented when the loudspeaker box works, and when the loudspeaker box does not work, dust can be prevented from entering the loudspeaker by means of closure of the upper cover part and the lower cover part; accumulation of dust of the loudspeaker is avoided, and the loudspeaker box is protected; the service life of the loudspeaker box is prolonged; and the loudspeaker box with the structure can be used in daily life of people.
Description
technical field [0001] The invention relates to a dustproof sound box. Background technique [0002] Due to the long-term placement of existing speakers, dust is prone to accumulate on the metal mesh of the speaker, which affects the sound of the speaker. Since the speaker is an electronic device, it is inconvenient to clean the dust with water. In the long run, it will inevitably affect the sound of the speaker. Cause an impact and affect the use of the speaker. Contents of the invention [0003] The purpose of the present invention is to provide a dust-proof sound box, so as to avoid the accumulation of dust on the sound box, and then affect the use of the sound box. [0004] The solution of the present invention to solve the technical problem is: a dust-proof sound box, comprising: an upper cover and a lower cover, the upper and lower covers are connected by a number of telescopic rods, and the upper and lower covers are cylindrical Shape, the lower cover is provided ...
