Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.

The present invention provides a kind of good waterproof speakers of waterproof performance, and identical in the prior art as shown in Fig. 5 to Fig. 8 Be that waterproof speaker is cylindrical, but the inside of the 31 self waterproofing loudspeaker of horn vibration lead-out wires of coil of the waterproof speaker is prolonged The front end of waterproof speaker is extended to, and is fixed on the front end via loudspeaker solder joint 32, the side of the waterproof speaker is arranged with bullet Property water proof ring.

Since horn vibration lead-out wires of coil 31 is walked inside waterproof speaker, so there is no need to add as the prior art in outside Protective glue 13, saves cost；And due to the side of waterproof speaker, i.e. cylindrical surface, it is arranged with elastic water-proof circle, in waterproof loudspeaker With earphone cavity 21 assemble when, it is seamless applying that elastic water-proof circle has accomplished the inner wall of waterproof speaker and earphone cavity 21, makes Water can not penetrate into from there；Elastic water-proof circle can fully ensure that the fastness of assembling simultaneously, also stablize waterproof speaker assembly.
