Description

Outdoor explosion-proof speaker that dustproof effect is good Technical Field The utility model relates to the technical field of loudspeakers, in particular to an outdoor explosion-proof loudspeaker with a good dustproof effect. Background As an audio playing device widely used in an outdoor environment, an outdoor speaker is required to have various characteristics to accommodate a complicated use scene. In dangerous places such as petroleum, chemical industry, oil depot, natural gas exploitation, drilling platform, port, wharf, medicine, mine and the like containing inflammable and explosive gas, the explosion-proof performance of the loudspeaker is strictly required.
