[0031] Specifically, such as Figure 4As shown, a speaker tray 405 is embedded in the top of the panel 402. The speaker tray 405 is located on the top of the protective cover 401, and a slot 9 is provided on the top of the speaker tray 405.

[0032] In this embodiment: By setting a cover plate structure 4, the protective cover 401 is bolted to the top of the housing 1, which protects the circuit board 301 and prevents dust, moisture and other impurities from entering the housing 1 and damaging the circuit board 301 and other components. The panel 402, which is snapped onto the top of the protective cover 401, makes the phone more integrated and aesthetically pleasing. The key dial 403 and hands-free key 404 embedded on the panel 402 facilitate user operation and are directly electrically connected to the circuit board 301, ensuring that commands can be received and processed quickly and accurately by the circuit board 301, thus improving the ease of operation. The speaker tray 405 embedded on the top of the panel 402 is located on the top of the protective cover 401 and has a slot 9, which not only ensures that the sound of the speaker 305 can be effectively transmitted, but also further optimizes the appearance design of the phone, making it more aesthetically pleasing while ensuring functionality. At the same time, the speaker tray 405 may also have a certain sound focusing and diffusion effect, which helps to improve the sound quality and enhance the user's voice interaction experience.

[0033] Specifically, such as Figure 5 As shown, an expansion interface 5 is embedded in the bottom of the housing 1, and the expansion interface 5 is electrically connected to the circuit board 301.

[0034] Specifically, such as Figure 5 As shown, support columns 6 are fixedly connected to the four corners of the bottom side inside the housing 1. The top of the support column 6 passes through the top of the circuit board 301. A support plate 7 is fixedly connected to the outside of the support column 6. The support plate 7 is located at the bottom of the circuit board 301.

[0035] In this embodiment: the expansion interface 5 embedded in the bottom of the housing 1 is electrically connected to the circuit board 301, which makes it possible to expand the phone's functions. For example, other smart devices or external devices can be connected through the expansion interface 5, such as connecting a smart camera to realize video monitoring function, connecting an external storage device to store data, etc., which enhances the versatility and expandability of the device and meets the diverse needs of users.

[0037] Specifically, such as Figure 4As shown, a slot 9 is provided on the front side of the top of the panel 402, and the slot 9 is located on the top of the microphone 304.

[0038] In this embodiment: the backup battery 8 located on the bottom side inside the housing 1 is electrically connected to the power converter 302. When the mains power fails, the backup battery 8 can provide power support to the phone in time, ensuring the normal operation of basic functions and realizing uninterrupted emergency service. For example, when the hotel loses power, guests can still contact the front desk or control necessary equipment in the room through this device. By opening a slot 9 on the top front side of the panel 402 at the top of the microphone 304, it is ensured that the sound can enter the microphone 304 smoothly, improving the sound pickup effect of the microphone 304 and ensuring that the offline voice chip 303 can accurately recognize the user's voice commands, thereby realizing efficient voice control function and improving the smoothness and convenience of the user experience.

[0039] Working Principle: When using the offline voice phone, the user approaches the housing 1 and issues a voice command. The sound is received by the microphone 304 and converted into an electrical signal, which is then transmitted to the offline voice chip 303. The offline voice chip 303 uses its built-in vocabulary and algorithms to identify and compare the voice command. If it is a control command, the command is encoded and sent to the gateway chip 307 via the serial port. The gateway chip 307 uses the Bluetooth module 309 to send the command as a Bluetooth MESH signal to the indoor lighting control module to adjust the brightness. At the same time, it receives the execution result and feeds it back to the offline voice chip 303. The chip then triggers the speaker 305 to broadcast the result, completing the voice control process. During a call, the phone line is connected through the terminal 2. The electrical signal is processed by the power converter 302 to power the components. When a call comes in, the optocoupler 306 senses the ringing signal and transmits it to the circuit board 301 system to trigger the ringing prompt. After the user picks up the phone, its output off-hook signal puts the phone into call mode, and the sound is transmitted through the speaker 305. If hands-free calling is required, the hands-free button 404 on the panel 402 is pressed, and the circuit controls the relay 308. The speaker 305 is switched to the communication line for external playback. All components work together to ensure stable calls. The protective cover 401 is bolted to the top of the housing 1 to protect the circuit board 301 and prevent impurities from entering. The snap-fit ​​panel 402 makes the phone look beautiful and easy to operate. The keypad 403 and hands-free key 404 are electrically connected to the circuit board 301 for easy command transmission. The speaker tray 405 is located on top of the protective cover 401, and its slot 9 ensures sound transmission, while also optimizing the appearance and improving sound quality. The expansion interface 5 at the bottom of the housing 1 is electrically connected to the circuit board 301, which facilitates the connection of other devices to expand functions and meet diverse user needs. The four internal corner supports 6 and the support plate 7 provide stable support for the circuit board 301.
