Drum type no. Explosion-proof loudspeaker Explosion-proof speaker Explosion-proof radio Outdoor fire loudspeaker

This kind of structure of loudspeaker according to the different internal electrical components can be divided into: passive explosion-proof speaker passive and active explosion-proof speaker JDYS explosion-proof speaker (speaker) is constant pressure type high horn speaker (can be set according to user requirements to provide resistance type), suitable for installation in Ⅱ C level T6 explosive gas environment, temperature classes for live broadcasting and amplification. This product meets the requirements of GB3836 series standard, and has obtained the explosion-proof certificate through the identification of the national designated testing institution. This loudspeaker has the characteristics of reasonable structure, beautiful shape, sound macro, high fidelity, reliable performance and easy installation. JDYS active explosion-proof speaker is suitable for installation in Ⅱ C level T6 explosive gas environment, temperature classes for live broadcasting and amplification. Since there is a 15W power amplifier inside, small signal transmission mode can be used, so users do not need to be equipped with large power amplifier. This product meets the requirements of GB3836 series standard, and has obtained the explosion-proof certificate through the identification of the national designated testing institution. The explosion-proof loudspeaker features low signal attenuation, reasonable structure, beautiful appearance, sound macro, low distortion, reliable performance and easy installation. 1.
