Embodiment Construction

[0012] The present invention will be described in further detail below in combination with specific embodiments and accompanying drawings.

[0013] Such as Figures 1 to 2 As shown, the waterproof sound box includes a casing 100, an opening 101 is arranged on the casing 100, a horn 200 is arranged at the opening 101, a fan 300 is arranged on the top of the casing 100, and the fan 300 includes The casing 301 and the fan blade 302, the casing 301 is closely matched with the casing 100, the bottom inner ring of the casing 301 is provided with a ring of grooves 303, the bottom of the groove 303 is provided with a through hole, the through hole 304 is connected to one end of the heat dissipation pipe 400 , and the heat dissipation pipe 400 passes through the bottom of the casing 100 after bypassing the horn 200 .

[0014] In order to prevent some water from entering from the blades or the gaps between the blades and corroding the internal components, a water-proof cavity 110 is pr...

Abstract

The invention discloses a waterproof sound box, which comprises a casing, wherein an opening is formed in the casing; a loudspeaker is arranged in the opening; the top of the casing is provided with a fan; the fan comprises a shell and fan blades; the shell is tightly matched with the casing; a circle of groove is formed in an inner ring at the bottom of the case; a through hole is formed in the bottom of the groove; the through hole is connected with one end of a heat radiation pipe; the heat radiation pipe bypasses the loudspeaker and then passes out of the bottom of the casing. When the waterproof sound box is used at ordinary times, under the effect of the fan, air flow flows through the heat radiation pipe; heat radiated at the loudspeaker part is taken away when the air flow flows. During raining, raindrops can fall on the fan blades rotating at high speed; then, under the effect of centrifugal force, the raindrops are thrown onto the inner side wall of the shell, then drip into the groove along the inner side wall and flow into the heat radiation pipe along the groove; when the raindrops flow in the heat radiation pipe, the heat generated in the loudspeaker position is taken away; water flow is completely limited in the range of the heat radiation pipe, so that the waterproof requirement is also met.

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...
