SP TELEPHONE SYSTEMS

The energy required to communicate comes only from the sound of the user. Acoustic energy is converted into electricity and then from electrical to acoustic. All of our voice-operated phones are made of polymer alloy which provides excellent chemical resistance, high impact resistance, non-flammability and stability to ultraviolet light. Such telephones are used in situations where security is critical in communication, such as in combat systems on military ships. Our sound-powered telephone systems are MIL-STD compliant.
