roadside telephones rely on clear and stable voice communication. For manufacturers, the microphone must meet acoustic requirements while matching the equipment&#8217;s electrical specifications, installation structure, and environmental conditions. When selecting or replacing a microphone, key factors such as microphone type, impedance, dimensions, sensitivity, directionality, and waterproof performance should be evaluated before moving to production. Why Microphone Selection Matters in Emergency Roadside Telephones Emergency roadside telephones are designed for critical communication in outdoor environments. The microphone needs to provide reliable voice transmission while operating under conditions such as rain, humidity, temperature changes, and long-term outdoor exposure.
