Description

Technical field [0001] The present invention relates to the field of broadcasting technology, in particular to a broadcasting terminal with a protective device. Background technique [0002] As the main part of the terminal of the broadcasting system, the speakers are often exposed outdoors all year round. Therefore, the waterproof of the speaker becomes particularly important. The waterproofing of the speaker is also very simple, we can make the speaker shell fully enclosed, which is not difficult to achieve technically. But in this case, it will cause poor heat dissipation of the speakers. Therefore, waterproofing and heat dissipation are a pair of contradictions. How to waterproof while ensuring heat dissipation is a problem that the present invention needs to solve. In addition, the broadcasting terminal is also easy to be damaged, especially naughty children, who often use slingshots to play. Speakers, so how to prevent the broadcasting terminal from being destroyed is al...
