Description

Technical Field

[0001] This utility model relates to the field of intercom terminal technology, and in particular to a networked intercom terminal and a network intercom system. Background Technology

[0002] A walkie-talkie terminal is a device used to enable real-time voice communication. It is widely used in hospitals, prisons, schools, banks and other places. Its core function is to transmit audio signals through analog or digital technology to ensure efficient communication between two or more parties.

[0003] In related technologies, traditional intercom terminals typically collect real human voice data, process it, and then transmit it to a speaker module for playback, enabling mutual calling and communication. However, in certain specific scenarios, it is desirable to conceal the true identity of the intercom terminal user. For example, during bid evaluation or tendering processes, evaluation experts and bidders need to communicate via voice without identifying each other to prevent collusion and biased scoring; in banking or security systems, when remotely commanding and handling emergencies, the commander's identity must be kept confidential to ensure operational safety. Current intercom terminals struggle to meet the needs of these special scenarios, resulting in limited practicality and a poor user experience.

[0038] The following is a detailed description of a networked intercom terminal provided in the embodiments of this application, with reference to the specific accompanying drawings.

[0039] This application provides a networked intercom terminal, specifically referring to... Figure 1 The networked intercom terminal provided in this application embodiment mainly includes:

[0040] Microprocessor module, voice changing module, sound pickup module, sound amplification module, display module, and network module;

[0041] The output of the pickup module is connected to the input of the voice-changing module. The pickup module receives input human voice data and transmits the human voice data to the voice-changing module. The output of the voice-changing module is connected to the input of the microprocessor module. The output of the microprocessor module is connected to the input of the sound reinforcement module. The microprocessor module is also connected to the display module and the network module. The network module is used to communicate with other networked intercom terminals through a network switch.

[0042] This application provides a networked intercom terminal, whose main architecture includes a microprocessor module, a voice changing module, a sound pickup module, a sound amplification module, a display module, and a network module. The modules work together to achieve efficient and secure voice communication, making it suitable for various application scenarios.

[0043] Specifically, in this embodiment, the microphone module of the networked intercom terminal is responsible for collecting sound data from the environment, especially human voice data, and converting it into electrical signals. For example, in some embodiments, the microphone module may employ a high-sensitivity microphone array to ensure clear voice data pickup even in complex environments. The output of the microphone module is connected to a voice-changing module, which can transmit the collected raw audio signal to the voice-changing module for further processing.

[0044] Please refer to Figure 2 , Figure 2 The diagram illustrates a circuit diagram of a microphone pickup module provided in an embodiment of this application. In this embodiment, the capacitors, resistors, and transistors within the microphone pickup module can form a small signal amplifier. A U1SGM8904 chip can be integrated within it. The U1SGM8904 chip is a high-performance, low-noise operational amplifier chip designed specifically for audio signal processing. This chip employs a low-power architecture, featuring a high gain-bandwidth product and low distortion characteristics, effectively amplifying weak microphone signals while suppressing environmental noise interference. It integrates multiple stages of amplification circuitry, supports single-supply operation, and facilitates stable operation in a compact circuit layout. In this embodiment, the raw audio signal acquired by the microphone pickup module, after processing by the U1SGM8904 chip, can be output to the voice-changing module.

[0045] The voice-changing module performs real-time timbre transformation on the input human voice data to conceal the speaker's true voice characteristics. This module employs digital signal processing techniques, such as frequency shifting and formant adjustment, to process the human voice data, ensuring that the output speech retains its original meaning while making it difficult to easily identify the original speaker. It should be noted that the voice-changing module used in this embodiment is a pre-packaged functional module; the specific voice-changing processing logic within it is not adjusted, meaning this application does not involve any algorithmic improvements. The output of the voice-changing module is connected to a microprocessor module, which handles subsequent signal scheduling and transmission control.

[0046] For example, please refer to Figure 3 , Figure 3 This paper illustrates a circuit diagram of a voice-changing module provided in an embodiment of this application. Figure 3As shown in this embodiment, the voice-changing module may include a BP1048 chip, as well as some peripheral resistors, capacitors, and a crystal oscillator circuit. The BP1048 chip has a built-in high-performance digital signal processor (DSP) that supports real-time timbre changing. It can achieve a natural and smooth voice-changing effect while maintaining speech clarity by adjusting characteristic parameters such as the fundamental frequency and formants of the speech signal. The crystal oscillator circuit provides a precise clock signal to the BP1048 chip, ensuring the timing synchronization of digital signal processing. Specifically, the crystal oscillator circuit may include a crystal oscillator, a 20th capacitor, and a 25th capacitor. The first terminal of the crystal oscillator is connected to the 15th pin of the BP1048 chip and the first terminal of the 25th capacitor; the second and fourth terminals are grounded; the second terminal of the 25th capacitor is grounded; the third terminal of the crystal oscillator is connected to the 16th pin of the BP1048 chip and the first terminal of the 20th capacitor; and the second terminal of the 20th capacitor is grounded.

[0047] In this embodiment, the microprocessor module serves as the core control unit of the entire system, responsible for coordinating the operation of various modules, including audio data encoding / decoding, signal routing, and communication protocol processing. This module can be implemented based on a high-performance embedded processor, supporting real-time multi-task scheduling to ensure low-latency transmission of voice data. For example, please refer to... Figure 4 , Figure 4 A circuit diagram of a microprocessor module provided in an embodiment of this application is shown, such as... Figure 4 As shown, in some embodiments, the microprocessor module may include an MT6582 chip. The output of the microprocessor module is connected to the sound reinforcement module to drive the sound reinforcement module to play the processed audio signal. In addition, the microprocessor module is also connected to a display module and a network module to realize human-computer interaction interface management and network communication functions.

[0048] In this embodiment, the sound reinforcement module amplifies the audio signal output by the microprocessor module and converts it into sound waves. It can employ a combination of a high-fidelity power amplifier circuit and a speaker to ensure clear and distinguishable sound. For example, please refer to... Figure 5 , Figure 5 The diagram illustrates a circuit diagram of a sound reinforcement module according to an embodiment of this application. In this embodiment, the sound reinforcement module may include an AD52068 chip and a speaker. The AD52068 chip is designed for portable electronic devices and embedded audio systems, capable of providing high output power while maintaining extremely low harmonic distortion. Furthermore, the number of speakers in the sound reinforcement module can be multiple; this application does not limit this.

[0049] In this embodiment, the display module of the networked intercom terminal provides a visual interactive interface for displaying information such as device status, communication mode, and volume adjustment. This module may include a display and a touchscreen module, allowing users to quickly adjust parameters or view relevant data. The network module is responsible for establishing communication connections with other intercom terminals via a network switch. It supports wired (e.g., Ethernet) or wireless (e.g., Wi-Fi, 4G / 5G) communication methods. This module has a built-in network protocol stack, enabling low-latency, highly reliable data transmission and supporting encryption technologies (e.g., AES, TLS) to ensure communication security. Through the network module, multiple intercom terminals can form a distributed communication network, suitable for cross-regional, multi-node collaborative operation scenarios.

[0050] For example, please refer to Figure 6 , Figure 6 The diagram shows a circuit schematic of a network module provided in an embodiment of this application, such as... Figure 6 As shown in the embodiments of this application, the network module may include a network interface and a DM9621 chip. The network interface may be an RJ45 interface. The DM9621 chip is a highly integrated USB 2.0 to 10 / 100M Ethernet controller with built-in IEEE 802.3 compliant MAC and PHY layer functions, supporting full-duplex and half-duplex communication modes, and capable of achieving a stable and reliable wired network connection through a standard RJ45 network interface.

[0051] This application embodiment also provides a network intercom system, which may include a network switch and multiple aforementioned networked intercom terminals. For example, please refer to... Figure 7 , Figure 7 This application provides an embodiment of a network intercom system, as illustrated in the schematic diagram. Figure 7 As shown, each networked intercom terminal can be denoted as Terminal 1, Terminal 2, Terminal 3... Terminal N. In practical applications, N can be a value greater than or equal to 2, and this application does not impose any restrictions on this. Each networked intercom terminal can be connected via a network switch, thus enabling the transmission of related audio signals between the networked intercom terminals to achieve the intercom effect.
