[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A three-in-one offline voice phone includes a bottom shell 1, a board frame 2 is provided at the bottom of the bottom shell 1, a panel 3 is snapped onto the bottom of the board frame 2, an integrated mechanism 4 is provided inside the bottom shell 1, a support structure 5 is provided at the bottom of the integrated mechanism 4, and an LN connector 6 is embedded in the bottom of the bottom shell 1.

[0027] The integrated mechanism 4 includes an integrated circuit board 401 disposed inside the bottom shell 1. The integrated circuit board 401 is electrically connected to the LN connector 6. A telephone transmitter 402 and an offline voice transmitter 403 are respectively disposed on the right side of the top of the integrated circuit board 401. A call button 404 and an answer button 405 are respectively disposed on the front and rear sides of the top right side of the integrated circuit board 401. A gateway chip 406 is disposed on the left side of the top of the integrated circuit board 401. A main transmission chip 407 is disposed on the left side of the top of the integrated circuit board 401. A Bluetooth sensor module 408 is disposed on the front side of the top of the integrated circuit board 401. A speaker 409 is disposed on the top of the integrated circuit board 401.

[0028] In this embodiment: by setting up an integrated mechanism 4, the traditional call function is ensured through the telephone transmitter 402, answer button 405, call button 404 and speaker 409, meeting the basic communication needs of guests with the front desk or external parties. The offline voice transmitter 403 works in conjunction with the gateway chip 406, main transmission chip 407 and Bluetooth sensor module 408, enabling guests to easily control room lights, air conditioning, curtains and other devices through voice commands, realizing convenient contactless control, providing guests with a technologically advanced living experience, and conforming to the modern intelligent development trend. At the same time, this integrated design avoids placing multiple scattered devices in the guest room, effectively saving limited space such as bedside tables and desktops, making the guest room layout more concise and spacious, and improving space utilization. Meanwhile, the bottom shell 1, frame 2, panel 3 and support structure 5 together constitute... The overall architecture provides stable physical support for the telephone. The support structure 5 ensures the stable installation of the integrated mechanism 4 inside the base shell 1, enabling it to withstand certain external impacts and vibrations during daily use and maintain normal operation, thus improving the reliability and durability of the equipment. The snap-fit ​​method between the frame 2 and the panel 3, as well as the reasonable layout of each component inside the base shell 1, not only facilitates the embedded installation of the telephone on the hotel room wall, allowing the telephone to better integrate with the room's decoration style, but also facilitates later maintenance and repair work. When the equipment malfunctions, maintenance personnel can relatively easily open the panel 3 to inspect and repair the internal integrated circuit board 401 and other components. In addition, the simple structural design reduces the surface area, lowers the difficulty of cleaning, reduces the labor intensity of hotel staff, and also reduces the consumption of cleaning supplies, thereby lowering the hotel's operating costs.

[0029] Specifically, such as Figure 5As shown, the support structure 5 includes a pillar 501 fixedly connected to the bottom side of the bottom shell 1. A lower plate 502 is fixedly connected to the top of the pillar 501, and the lower plate 502 is located at the bottom of the integrated circuit board 401.

[0030] Specifically, such as Figure 5 As shown, a reinforcing post 503 is provided at each of the four corners of the top of the integrated circuit board 401. The bottom of the reinforcing post 503 penetrates through the top of the integrated circuit board 401, and the bottom of the reinforcing post 503 is threaded to the top of the support post 501.

[0031] Specifically, such as Figure 5 As shown, a positioning disk 504 is snapped onto the outer side of the reinforcing column 503, and the positioning disk 504 is located on the top of the integrated circuit board 401.

[0032] In this embodiment: the support column 501 provides vertical support for the entire support system. The lower plate 502, which is fixedly connected to the top of the support column 501, has a large area and can evenly distribute the weight of the integrated circuit board 401, preventing excessive local pressure from damaging the integrated circuit board 401. The reinforcing columns 503 set at the four corners of the top of the integrated circuit board 401 penetrate the integrated circuit board 401 at the bottom and are threaded to the top of the support column 501. This threaded connection makes the connection between the reinforcing column 503 and the support column 501 tight and stable, which can effectively prevent the integrated circuit board 401 from shaking in the horizontal and vertical directions. The positioning plate 504, which is snapped on the outside of the reinforcing column 503, is located on the top of the integrated circuit board 401, which further fixes the position of the reinforcing column 503, and also provides a certain limit and protection for the integrated circuit board 401, preventing the integrated circuit board 401 from being displaced due to accidental collision.

[0033] Specifically, such as Figure 4 As shown, a protective mesh frame 7 is embedded in the top of the plate frame 2, and the protective mesh frame 7 is located on the top of the speaker 409.

[0034] Specifically, such as Figure 3 As shown, a loudspeaker hole 8 is provided at the top of panel 3, and the loudspeaker hole 8 is located at the top of protective mesh frame 7.

[0035] In this embodiment, the protective mesh frame 7 greatly protects the safety of the speaker 409. In a hotel room environment, there may be small foreign objects such as dust and hair. The protective mesh frame 7 can block these foreign objects from entering the speaker 409, preventing the accumulation of foreign objects from affecting the sound output of the speaker 409 or causing damage to the speaker 409. This ensures the normal operation of functions such as voice prompts, call sound playback, and control result broadcasting. The speaker grille 8 optimizes the sound propagation effect, allowing guests to hear the sound from the phone more clearly. Whether it is the voice of the other party or the feedback information of voice control, it can be better received by guests, improving the user experience. At the same time, the combined design of the protective mesh frame 7 and the speaker grille 8 not only ensures the sound propagation quality but also improves the overall protection performance of the phone, reduces equipment failure caused by external factors, and lowers maintenance costs.

[0036] Specifically, such as Figure 5 As shown, a spare battery 9 is provided on the left side of the bottom inside the bottom shell 1, and the spare battery 9 is electrically connected to the integrated circuit board 401.

[0037] Specifically, such as Figure 5 As shown, the bottom shell 1 adopts the 86-type panel method. A connecting post 10 is fixedly connected to the left side of the bottom of the bottom shell 1. The top of the connecting post 10 penetrates the bottom of the integrated circuit board 401.

[0038] In this embodiment, the backup battery 9 provides emergency power for the integrated circuit board 401, ensuring that guests can still contact the front desk during a hotel power outage. This is crucial for guest safety and responsiveness, reflecting the human-centered and reliable design of the phone. The 86-type panel design of the bottom shell 1 makes the phone more adaptable to hotel room decorations and simplifies and speeds up installation, requiring no special installation tools or additional accessories, thus reducing installation costs and time. The connecting column 10 enhances the stability of the integrated circuit board 401 and, together with the support structure 5, further improves the stability of the integrated circuit board 401, reducing equipment failures caused by problems such as loosening of the integrated circuit board 401.

[0039] Working Principle: When using the three-in-one offline voice phone in a hotel room, first connect the LN connector 6 embedded in the bottom of the casing 1 to the room's telephone line to obtain power and establish a connection with the external communication network. Then, when the guest needs to use the traditional call function, press the call button 404, the circuit is connected, and the guest speaks into the telephone transmitter 402. The voice signal is converted into an electrical signal by the telephone transmitter 402. After being amplified and filtered by the relevant signal amplifiers and other structures on the integrated circuit board 401, the electrical signal is transmitted to the telephone communication network through the LN connector 6 and finally reaches the front desk. When there is an incoming call, the ringing signal is transmitted to the phone through the LN connector 6. After the integrated circuit board 401 detects the ringing signal, it drives the speaker. 409 emits a ringing sound to alert the guest of an incoming call. Upon hearing the ring, the guest presses the answer button 405 to establish a call connection and communicate with the caller. The call audio is played back through speaker 409, allowing the guest to hear the other party. If the guest wants to use the voice control function to operate the room's devices, they can speak according to the set wake-up word. The offline voice transmitter 403 collects the sound signal in real time. Upon detecting the wake-up word, it begins to recognize subsequent voice commands. For example, if the guest wants to turn on the lights, the offline voice transmitter 403 converts the sound command into an electrical signal and transmits it to the integrated circuit board 401. The main transmission chip 407 and related processing circuits on the integrated circuit board 401 analyze and process the electrical signal. The system outputs the command content and then transmits the command information to the gateway chip 406 via a serial port. The gateway chip 406, based on the command content, sends the control signal to the corresponding lighting control module in the room via the Bluetooth sensor module 408 using the Bluetooth MESH protocol. Upon receiving the signal, the lighting control module turns on the lights and sends the result back to the gateway chip 406. The gateway chip 406 then transmits the result information to the integrated circuit board 401. The integrated circuit board 401 drives the offline voice transmitter 403 and speaker 409 to broadcast voice feedback to the guest, indicating that the control operation has been successfully executed. Throughout the entire process, the support structure 5 includes the pillar 501, the lower plate 502, the reinforcing pillar 503, and the positioning plate 5. 04. Together, they ensure the stable operation of the integrated circuit board 401 and its functional components. The support column 501 provides vertical support, the lower plate 502 distributes the weight of the circuit board, the reinforcing column 503 prevents the circuit board from shaking, the positioning plate 504 assists in fixing and protecting the circuit board, the protective mesh frame 7 on the top of the board frame 2 effectively prevents dust and other foreign objects from entering the speaker 409, ensuring normal sound output, the sound amplification hole 8 on the panel 3 optimizes the sound propagation effect and enhances the guest's auditory experience, in the event of a hotel power outage, the backup battery 9 automatically starts to power the integrated circuit board 401, the bottom shell 1 adopts the 86-type panel design for easy wall mounting of the telephone, and the connecting column 10 enhances the stability of the integrated circuit board 401 within the bottom shell 1, ensuring that the telephone can work reliably in various environments.We continue to provide guests with convenient calling and smart device control services.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
