Adopt technique scheme, by annular flanging is set in, on circular orientation limit, realize being connected of loudspeaker and sounder resonator, like this can be for convenience detach, install also and facilitate; At the O-ring seal arranging between circular orientation limit and annular flanging, make good airproof performance between circular orientation limit and annular flanging, thereby make big opening end and the loudspeaker junction good airproof performance of sounder resonator, and then assurance acoustic energy can well be demonstrated.
Further setting of the present utility model: described circular orientation limit is provided with annular groove, described O-ring seal is embedded in described annular groove, and described O-ring seal and annular groove inwall are fixed through fixing glue.
Adopt above-mentioned further setting, due to when dismantling sounder resonator, in order to prevent sounder resonator, O-ring seal is pulled down in the lump, and O-ring seal is under by sounder resonator band time, can produce distortion, again install and can affect its sealing effectiveness, and by the annular groove arranging, O-ring seal and annular groove inwall are fixed through fixing glue, can well O-ring seal be fixed, thus big opening end and the loudspeaker junction good airproof performance of assurance sounder resonator.
Further setting more of the present utility model: described loudspeaker bottom is provided with support, described support includes base, on described base, be positioned at loudspeaker two side positions and be provided with back up pad, described back up pad and loudspeaker are welded and fixed, and described base and back up pad are welded and fixed.
Adopt above-mentioned further setting again, the support of setting can conveniently be placed loudspeaker, sounder resonator; And due to when demonstrating, loudspeaker can produce compared with big bang, the support of this structure and loudspeaker connected mode, it is firm to locate, and loudspeaker can not come off.
Further setting of the present utility model: the bottom of base is provided with rubber blanket, and described rubber blanket and base are fixed through fixing glue.
Adopt above-mentioned further setting, due to when demonstrating, loudspeaker can produce compared with big bang, and the rubber blanket of setting can reduce its vibration amplitude well.
