Description

Technical Field

[0001] This utility model relates to the field of mobile communication equipment technology, specifically to a multi-mode fusion terminal device with an ultrasonic encapsulation and encrypted power supply system. Background Technology

[0002] A multi-mode fusion intercom terminal is a communication device that integrates multiple communication methods. The device has a built-in intelligent switching mechanism, which allows the device to automatically or manually select the optimal communication mode (such as digital or analog) according to the current communication environment. Digital mode has the advantages of strong anti-interference, high voice clarity and high spectrum utilization, and is suitable for long-distance, high-quality communication. Analog mode, on the other hand, still plays an important role in specific scenarios due to its good compatibility and low equipment cost. This multi-mode capability greatly improves the adaptability and flexibility of the intercom, ensuring stable communication under different conditions.

[0003] In recent years, battery safety incidents involving electronic devices have been frequent, leading to increased public concern about battery safety. However, battery modification or the use of third-party batteries for power supply is a significant cause of potential battery safety hazards. Existing multi-mode fusion intercom terminals generally employ a removable and replaceable battery structure, with two positive and negative electrical contacts on the battery that are electrically connected to the multi-mode fusion intercom terminal. This allows users to freely use third-party batteries, and the lack of anti-tampering design makes battery modification relatively easy. This results in safety risks for subsequent use of the device, failing to meet user needs and hindering product competitiveness. Utility Model Content
