Description

Technical Field

[0001] The invention belongs to the technical field of dustproof and temperature control, and in particular relates to a dustproof and temperature-controlled outdoor speaker. Background Art

[0002] In public places such as parks, squares, and streets, the sound quality of most ordinary speakers is easily affected by the entry of dust. They cannot effectively block dust in dusty areas outdoors, which will affect the clarity of the sound and the cleanliness of the interior. In addition, most ordinary speakers cannot effectively control the temperature and dissipate heat, which affects the service life of the equipment.

[0003] According to the authorization publication number CN220359350U, a dustproof speaker is disclosed. When in use, the first protective shell 1 and the second protective shell 2 are combined on the outside of the speaker body 10 through the fixing bolts 4 on the first bolt seat 3, and then the dustproof net 7 is fixed in front of the speaker body 10 through the positioning bolts 9 on the mounting frame 6. The protective shell and the dustproof net 7 can be used to prevent dust from accumulating when the speaker is in use, so that the speaker can be used better. The spring 115 and the rubber gasket 114 can perform shock absorption and buffering, so that the speaker body 10 is safer and more stable in the first protective shell 1 and the second protective shell 2.
