What Is A Loudspeaker Phone

Loudspeaker telephone is a telephone that combines telephone and broadcasting functions to achieve remote scheduling and broadcasting. Due to the extremely harsh and noisy working environments in our country, such as power plants, mining sites conducting blasting operations, areas near airports and docks, and factory areas with particularly high noise levels. When an emergency occurs, ordinary telephones or mobile phones have become mere decorations. It is crucial to quickly establish contact with on-site operators and achieve remote dispatch.
Specific requirements:
1. Loudspeaker phones must have anti noise function, that is, noise filtering, and the other party must be able to hear the sound on site clearly;
2. Loudspeaker phones must be equipped with high-power speakers, and when a phone is connected, the speakers must be able to alert the on-site operators;
3. When on-site operators are unable to answer the phone, the telephone must be able to start on its own and amplify the sound on site through a speaker to achieve remote broadcasting and scheduling;
4. After the call ends, it must be able to automatically hang up for the next use.
