The explosion-proof Bugle loud of Industrial Engineering, including shell and the sounding component in shell, on the sounding component Side is equipped with eqalizing cricuit, is bonded and is equipped with for explosion-proof burst disk, the burst disk and shell top above the eqalizing cricuit The middle cylinder of the outer barrel of connection contradicts connection, and the middle cylinder is fixedly mounted on the middle part of outer barrel, the shell below the sounding component Transformer is inside installed, the transformer is fixedly mounted inside housings, and being powered below the transformer is connected with ceramic wiring Plate, the ceramics terminal plate and external binding post are powered and connect, and the binding post is fixedly mounted on the outside of shell；

The sounding component includes sound film, and the sound film covering is mounted on U iron, and the U ferropexies are mounted in shell On the holder in portion.

Further, the shell and the external rings set of outer barrel junction are useful for loudspeaker installing fixed mounting bracket.

Further, the shell is made of aluminum alloy materials, effectively explosion-proof while ensureing overall structure.

Further, the burst disk is that the gas permeability flame proof piece of high-performance, high-density makes.

Further, the binding post is double binding post structures, and the binding post is distributed along loudspeaker axisymmetrical.

Compared with prior art, the utility model has the beneficial effects that：A kind of explosion-proof Bugle loud of Industrial Engineering, by adopting With highly dense gas permeability flame proof piece, shorten the transmitting range in sound channel, reduces internal energy loss；Using channel separation；Avoid sound The sound air-flow in intracavitary portion is interfered, and internal energy consumption is reduced；Using phase plug, the frequency response of lifting system internal high frequency component is special Property；Global design is small, and power is efficient greatly；The filling closing of internal resin prevents inside spark.
