Abstract

The invention discloses a waterproof loudspeaker box, comprising a shell. An opening is arranged on the shell. A loudspeaker is arranged at the opening. A fan is arranged on the top of the shell. The fan comprises an enclosure and fan blades. The enclosure is in close fit with the shell. A ring of groove is arranged at the inner ring of the bottom of the enclosure. A through hole is arranged at the bottom of the groove. The through hole is connected with one end of a heat dissipation pipe. The heat dissipation pipe bypasses the loudspeaker and penetrates out of the bottom of the shell. A first airflow valve is arranged at the bottom of the shell.

Description

technical field [0001] The invention relates to the technical field of broadcasting, in particular to a sound box for a broadcasting terminal. Background technique [0002] As the main part of the terminal of the broadcasting system, the speaker is often exposed to the outdoors for many years. Therefore, the waterproof of the speaker becomes particularly important. The waterproofing of the speaker is also very simple. We can make the shell of the speaker fully enclosed, which is not difficult to achieve technically. But in this case, it will cause poor heat dissipation of the speaker. Therefore, waterproofing and heat dissipation are a pair of contradictions, how to waterproof under the situation of ensuring heat dissipation is a problem to be solved in the present invention. Contents of the invention [0003] The invention aims at the deficiencies in the prior art, and provides a waterproof sound box, which can meet the requirement of heat dissipation while being water...
