Description

Technical Field

[0001] This utility model belongs to the technical field of videophones, specifically a touchscreen videophone. Background Technology

[0002] A telephone, as a two-way voice transmission terminal device, mainly consists of a microphone, receiver, keypad, ringer, and line interface. The microphone is responsible for converting sound signals into electrical signals, while the receiver works in reverse, converting electrical signals back into sound. When a user dials using the keypad, the control circuit sends the number out in a specific signal format, and the ringer emits a notification sound when a call comes in. Early telephones used PSTN wired connections for wired communication. With the development of technology, wireless telephones such as mobile phones, which use electromagnetic waves for communication, emerged. In addition, VoIP calls were realized by integrating network technology.

[0003] In remote mountainous areas and post-disaster reconstruction areas, traditional PSTN landline phones face challenges such as high construction costs, difficult construction, and long construction periods due to the need to lay a large number of lines, making it difficult to achieve rapid coverage. For elderly people with cognitive decline, they often have difficulty remembering phone numbers due to memory loss and cannot dial smoothly. Elderly people with dementia can only recognize familiar people, making conventional dialing methods ineffective for them. In addition, illiterate children cannot accurately identify and input numbers, making it difficult to contact the required person through traditional telephones in case of emergencies or when they need to make a call, thus making it difficult to meet their communication needs.

The wireless communication module 402 automatically searches for and connects to available WiFi or 4G networks to enable the device to connect to the network and support free calls. When the user issues a voice command, the voice recognition module 403 receives and recognizes the voice content and transmits the recognition result to the main controller 401. The main controller 401 quickly retrieves contact information from the storage module 404 according to the command and displays it on the display screen 2.

[0027] If a user needs to make a video call, the camera module 405 collects video image data, transmits it to the main controller 401 for processing, and then sends it to the other party through the wireless communication module 402. At the same time, it is displayed on the local display screen 2. In the audio module 406, the microphone collects the voice signal, converts it into an electrical signal, and transmits it to the main controller 401. After processing, it is played by the listening microphone 7 (earpiece assembly 407) to realize voice interaction.

[0028] When the emergency call button 9 is triggered, the main controller 401 controls the wireless communication module 402 to make a phone call to the preset emergency contact in the storage module 404. At the same time, the camera module 405 and the audio module 406 are activated to transmit the on-site audio and video information to the emergency contact, thus completing the emergency rescue operation.
