[0030] This application provides a wired simultaneous interpretation digital device to solve the technical problem that existing wired simultaneous interpretation systems using analog audio transmission methods experience a significant decrease in signal quality and increased noise during long-distance transmission.

[0031] Example 1:

[0032] Figure 1 This is a connection diagram of the wired hand-in-hand simultaneous interpretation digital device according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the simultaneous interpretation digital microphone in the wired hand-in-hand simultaneous interpretation digital device according to an embodiment of this application. Figure 3 This is a schematic diagram of the control system framework in the wired hand-in-hand simultaneous interpretation digital device according to an embodiment of this application. Figure 4 This is a circuit diagram of the control system in the wired hand-in-hand simultaneous interpretation digital device according to an embodiment of this application.

[0033] like Figure 1As shown in the figure, this application embodiment provides a wired simultaneous interpretation digital device, including multiple simultaneous interpretation digital microphones 10, which are connected in series and then connected to the host 20.

[0034] It should be noted that after one simultaneous interpretation digital microphone 10 is connected to the host, multiple simultaneous interpretation digital microphones 10 are then connected in series and then connected to the host. This wired daisy-chain simultaneous interpretation digital device achieves wired digital transmission through the series connection of multiple simultaneous interpretation digital microphones 10. The physical connection provides extremely high stability and reliability, strong anti-interference, and is not affected by any wireless interference or frequency conflict. The signal is enclosed in the physical cable, making it impossible for external eavesdropping, ensuring extremely high confidentiality and eliminating problems such as signal delay and crosstalk.

[0035] Understandably, this wired daisy-chain simultaneous interpretation digital device uses multiple simultaneous interpretation digital microphones 10 connected in series to form a wired daisy-chain transmission structure with the host 20. All the simultaneous interpretation digital microphones 10 are connected in series via a single backbone cable, and ultimately only one line is needed to return to the host. The wiring of this wired daisy-chain transmission structure is extremely simple, aesthetically pleasing, and not easily moved or lost, and it is also low-cost and cost-effective. Furthermore, by adopting a wired daisy-chain transmission structure, the number of communication cables for multiple simultaneous interpretation digital microphones 10 is reduced, energy consumption is lowered, conference costs are significantly reduced, and the economic efficiency of the wired daisy-chain simultaneous interpretation digital device is improved, better meeting the needs of large-scale international conferences.

[0036] like Figure 1 As shown in the embodiment of this application, the wired daisy-chain digital simultaneous interpretation device uses multiple simultaneous interpretation digital microphones connected in series to form a wired daisy-chain transmission structure, which makes it easy to add or remove simultaneous interpretation digital microphones. It is only necessary to insert or remove a simultaneous interpretation digital microphone at any node of a trunk cable and adjust the subsequent connections, without modifying the trunk cable.

[0037] like Figure 2 As shown in the embodiments of this application, each simultaneous interpretation digital microphone 10 includes a base 11 and a main control board (not shown in the figure) mounted on the base 11.

[0038] It should be noted that the base 11 primarily serves a supporting function, providing a mounting location for components such as the simultaneous interpretation digital microphone 10 and other components (e.g., the microphone itself). The main control board is the core control component of the simultaneous interpretation digital microphone 10, responsible for coordinating and managing the operation of various components within the device. The main control board typically integrates a central processing unit (CPU), memory, input / output interfaces, and other necessary circuits to execute preset program instructions, process data, and control the operation of peripheral devices. In this embodiment, the main control board primarily houses electronic components that enable digital network transmission, strong anti-interference capabilities, and high sound fidelity.

[0039] like Figure 3 and Figure 4 As shown in this embodiment, a control system is provided on the main control board. The control system includes a main control chip U10, an audio acquisition chip U14 and a network transceiver U96 connected to the main control chip U10, the network transceiver U96 is connected to the network transformer U4, and the network transformer U4 is connected to the host 20.

[0040] It should be noted that the main control board is equipped with a control system, which is mainly composed of the main control chip U10 as its core, and also integrates an audio acquisition chip U14 and a network transceiver U96 connected to the main control chip U10. The network transceiver U96 is further connected to the network transformer U4, which in turn provides a wired, daisy-chain simultaneous interpretation digital microphone connection with the host 20. The control system is implemented through the main control chip, audio acquisition chip, network transceiver, and network transformer. In this embodiment, the main control chip U10 can be an SSD20 series main control chip. The audio acquisition chip U14 can be a TLV320A series ADC audio acquisition chip, which can acquire audio data via Ethernet within a local area network. The network transceiver U96 can be an RTL82 series Ethernet transceiver chip. The network transformer U4 can be a HY60 series network transformer, mainly used for signal transmission, impedance matching, waveform repair, signal noise suppression, and high-voltage isolation. The network transformer U4 serves two main purposes: isolating the DC component and filtering out electromagnetic and electrostatic interference from the environment, thus protecting the chip. The signal emitted by the network transceiver U96 consists of a differential signal containing both DC and high-frequency AC components. The network transformer U4 couples the AC signal through electromagnetic induction while simultaneously blocking the DC component, ensuring that data transmission over the physical cable is free from direct electrical connections. The network acts like an antenna in the environment, receiving various electromagnetic interferences that can occur simultaneously on the network twisted pair. The network transformer U4 effectively suppresses this interference and, when subjected to electrostatic high-voltage surges, effectively blocks these high voltages from reaching the network transceiver U96 and the main control chip U10.

[0041] Understandably, a complete control system is meticulously designed on the main control board. This control system uses the main control chip U10 as its core control unit, playing a crucial role in overall coordination. Simultaneously, to achieve audio acquisition, the control system is also equipped with an audio acquisition chip U14 closely connected to the main control chip U10, capable of accurately capturing various audio signals. Furthermore, to meet network communication requirements, the network transceiver U96 is also connected to the main control chip U10, responsible for data transmission and reception. The network transceiver U96 is not directly connected to external devices; instead, it first connects to the network transformer U4. The network transformer U4 plays a vital role in signal conversion and isolation. Finally, the network transformer U4 establishes a connection with the host 20, thereby enabling network communication between the main control board and the host 20.

[0042] In this embodiment, the audio acquisition chip U14 acquires audio data via Ethernet within a local area network. The audio acquisition chip U14 is equipped with a DAC digital-to-analog converter. The DAC uses encoding technology and sampling and quantization methods to generate uncompressed pulse code modulation (PCM) audio data. The audio data is packaged into audio data packets using the UDP transmission protocol for transmission, and then the audio data and control data are exchanged via an Ethernet transceiver.

[0043] In this embodiment, the wired daisy-chain simultaneous interpretation digital device uses an audio acquisition chip and a network transceiver to form a digital audio transmission method. Audio is acquired through an Ethernet interface within a local area network, ensuring sufficient bandwidth. The audio acquisition chip's built-in encoding and decoding methods achieve clear, uncompressed, and original audio quality. As long as the cable connection is normal, the signal quality remains consistent, avoiding problems such as high noise levels during long-distance transmission.

[0044] It's important to note that after a simultaneous interpretation digital microphone picks up a person's voice, it converts it into binary code or digital signals that the audio acquisition chip can understand. This signal is then transmitted through various channels, such as the internet, Bluetooth, and WiFi. Finally, at the receiving end of the network transceiver, the main control chip converts it back into audible sound. Audio digital transmission is essentially a closed-loop process: analog → digital → transmission → digital → analog. For example... Figure 4 As shown, after the simultaneous interpretation digital microphone 10 picks up the sound, it is directly transmitted to the digital chip ADC of the audio acquisition chip U14. After being processed and converted into a comprehensible signal by the digital chip ADC, it is then processed and packaged by the main control chip U10 and sent to the network transceiver U96 for transmission.

[0045] This application provides a wired daisy-chain digital simultaneous interpretation device, comprising multiple digital simultaneous interpretation microphones connected in series to a host computer. Each microphone includes a base and a main control board mounted on the base. The main control board has a control system, which includes a main control chip, an audio acquisition chip connected to the main control chip, and a network transceiver. The network transceiver is connected to a network transformer, which is connected to the host computer. This wired daisy-chain digital simultaneous interpretation device avoids the problems of co-channel interference and electromagnetic interference that traditional wireless simultaneous interpretation technology is susceptible to, thus improving the stability and reliability of transmission. It acquires audio via Ethernet through the audio acquisition chip and network transceiver, generates PCM audio data through sampling and quantization, and packages it into audio data packets for network transmission, maintaining high-fidelity audio signal transmission. This solves the technical problem of significant signal quality degradation and increased noise during long-distance transmission in existing wired simultaneous interpretation systems using analog audio transmission.

[0046] It should be noted that this wired daisy-chain simultaneous interpretation digital device utilizes a wired digital transmission method that connects multiple simultaneous interpretation digital microphones in series. This effectively avoids wireless signal interference and the risk of eavesdropping, making the device more stable, secure, and reliable. It also solves the problem of high audio latency. In large international conferences, even with simultaneous translation in multiple languages, this wired daisy-chain simultaneous interpretation digital device can effectively achieve clear voice monitoring and translation, solving the problem of insufficient available channels. Furthermore, the device's control system achieves advantages such as strong anti-interference capability, low cost, high audio signal quality, and good stability.

[0047] like Figure 2 As shown in the embodiment of this application, each simultaneous interpretation digital microphone 10 also includes a microphone 1 mounted on a base 11. The microphone 1 is mounted on the base 11 via a microphone rod 12, and the microphone 1 is movably connected to the microphone rod 12.

[0048] It should be noted that each simultaneous interpretation digital microphone 10 is equipped with a microphone 1, which is mounted on the base 11. The microphone 1 is fixed to the base 11 by means of a microphone rod 12, and the microphone 1 and the microphone rod 12 are connected in a movable manner to ensure that the microphone 1 has the characteristic of flexible adjustment.

[0049] Understandably, each simultaneous interpretation digital microphone 10 includes a microphone 1, which is securely mounted on a base 11. The microphone 1 is connected to the base 11 via a specially designed microphone boom 12. The connection between the microphone 1 and the microphone boom 12 is not fixed but rather flexible, allowing the microphone 1 to rotate or adjust its angle within a certain range, thus better meeting the needs for sound acquisition direction and position in different usage scenarios.

[0050] like Figure 2 and Figure 4 As shown, in one embodiment of this application, the microphone 1 is provided with an illumination element 2 for illumination, and the illumination element 2 is also connected to the main control chip U10.

[0051] It should be noted that the lighting element 2 can be an LED light. In the design of the microphone 1, a lighting element 2 is specifically included to provide illumination. This lighting element 2 does not work independently but is connected to the main control chip U10. The main control chip U10 can precisely control the operating state of the lighting element 2, such as turning it on, off, and adjusting its brightness, to meet the needs of microphone illumination in different usage scenarios.

[0052] like Figure 2 As shown, in one embodiment of this application, each simultaneous interpretation digital microphone 10 also includes a touch screen 4 for human-computer interaction. The touch screen 4 is mounted on the base 11 and is connected to the main control chip U10.

[0053] It should be noted that the touchscreen 4 can be selected as a 4-inch square LCD touchscreen. Each simultaneous interpretation digital microphone 10 is equipped with a touchscreen 4 for realizing human-computer interaction functions. The touchscreen 4 is firmly installed on the base 11, and an electrical connection is established between the touchscreen 4 and the main control chip U10 to ensure the accurate transmission and processing of human-computer interaction commands.

[0054] Understandably, each simultaneous interpretation digital microphone 10 includes a touchscreen 4, which plays a crucial role in human-computer interaction. The touchscreen 4 is carefully mounted on the base 11 to ensure stability and ease of user operation. Furthermore, the touchscreen 4 does not operate independently; it is closely connected to the main control chip U10. Users can execute various commands on the touchscreen 4, which are quickly and accurately transmitted to the main control chip U10. The main control chip U10 then analyzes and processes these commands to implement corresponding human-computer interaction functions, providing users with a convenient and efficient user experience. For example, users can select the language and audiovisual language to be translated from the touchscreen 4.

[0055] like Figure 2 and Figure 4 As shown, in one embodiment of this application, the audio acquisition chip U14 is connected to the microphone rod 12 through the microphone interface P1, and a coupling capacitor C159 is connected between the microphone interface P1 and the audio acquisition chip U14.

[0056] It should be noted that after microphone interface P1 detects the sound from microphone 1, the translator speaks through microphone P1, connecting to input pins 6 and 13 of audio acquisition chip U14 via coupling capacitor C159. Audio acquisition chip U14 connects to microphone pole 12 via microphone interface P1. Coupling capacitor C159 is specifically configured between microphone interface P1 and audio acquisition chip U14 to perform key functions such as signal coupling and filtering. In this embodiment, the audio signal transmitted from microphone 1 first reaches microphone interface P1, and then is transmitted from microphone interface P1 to audio acquisition chip U14. To ensure signal transmission quality, a coupling capacitor C159 is specifically connected in the signal transmission path between microphone interface P1 and audio acquisition chip U14. Coupling capacitor C159 can effectively couple the signal and filter out some noise that may interfere with the signal, thus ensuring that audio acquisition chip U14 receives a relatively pure and stable audio signal.

[0057] like Figure 4 As shown, in one embodiment of this application, the microphone interface P1 is connected to a second power supply via an RC filter. The second power supply is used to provide a bias voltage to the electret condenser of the microphone 1.

[0058] It should be noted that the second power supply is a 5V DC voltage. The microphone interface P1 is connected to the second power supply via an RC filter. The main function of this second power supply is to provide the necessary bias voltage to the microphone electret condenser of microphone 1, ensuring that microphone 1 can function properly. The RC filter consists of resistors and capacitors; it filters the output voltage of the power supply, removing any noise and interference signals, making the voltage input to subsequent circuits more stable and pure. The microphone electret condenser is a key component for microphone 1 to achieve sound acquisition; a stable bias voltage ensures that the microphone electret condenser is in a normal working state, allowing microphone 1 to accurately acquire sound signals. In this embodiment, the RC filter includes a first resistor R1, a second resistor R2, and a second capacitor C2. The second power supply is connected to the first resistor R1, which is connected to both the second capacitor C2 and the second resistor R2. The second resistor R2 is connected to the coupling capacitor C159 and the microphone interface P1, and the second capacitor C2 is also grounded.

[0059] like Figure 4 As shown, in one embodiment of this application, the second capacitor also provides power to the microphone 1 through the twenty-second R22 and the twenty-tenth capacitor C20.

[0060] Figure 5 This is a schematic diagram of the structure of the simultaneous interpretation digital microphone in the wired hand-in-hand simultaneous interpretation digital device according to another embodiment of this application.

[0061] like Figure 4 and Figure 5 As shown, in one embodiment of this application, each simultaneous interpretation digital microphone further includes a microphone switch button 4, a volume control button 7, and a headphone jack 8. The microphone switch button 4, the volume control button 7, and the headphone jack 8 are all electrically connected to the main control chip U10.

[0062] It should be noted that the microphone switch button 4 is electrically connected to the main control chip U10 via switch S2, the volume adjustment button 7 is electrically connected to the main control chip U10 via interface terminal P2, and the headphone jack 8 is electrically connected to the main control chip U10 via interface terminal J1. In this embodiment, each simultaneous interpretation digital microphone is additionally equipped with a microphone switch button 4, a volume adjustment button 7, and a headphone jack 8. The microphone switch button 4, volume adjustment button 7, and headphone jack 8 all interact with the main control chip U10 via electrical connections.

[0063] Understandably, each simultaneous interpretation digital microphone also includes components for operating and connecting external devices. For example, there's a microphone switch button 4 to control the microphone 1's on / off state; users can easily control the microphone 1's operating status by pressing or releasing this button. There's also a volume control button 7 to adjust the volume according to actual needs; and a headphone jack 8 for connecting headphones for monitoring. The microphone switch button 4, volume control button 7, and headphone jack 8 do not operate independently; they are all electrically connected to the main control chip U10 through specific circuitry. User commands (such as turning the microphone on / off or adjusting the volume) are transmitted to the main control chip U10 via these buttons, and the main control chip U10 then processes and controls accordingly. Simultaneously, after the headphone jack 8 is connected to the main control chip U10, the main control chip U10 can transmit the processed audio signal to the headphones, achieving audio output.

[0064] In this embodiment, the wired daisy-chain simultaneous interpretation digital device features a built-in 4-inch display screen, multiple input and output channels, a microphone switch, volume control buttons, a headphone jack, and a microphone jack (such as a microphone jack), meeting the diverse needs of different users and improving the flexibility and applicability of the wired daisy-chain simultaneous interpretation digital device.

[0065] like Figure 1As shown, in one embodiment of this application, each simultaneous interpretation digital microphone 10 further includes a first connection interface 4 and a second connection interface 5. In two adjacent simultaneous interpretation digital microphones 10, the first connection interface 4 of one simultaneous interpretation digital microphone 10 is connected to the second connection interface 5 of the other simultaneous interpretation digital microphone 10.

[0066] It should be noted that the first connection interface 4 and the second connection interface 5 can be selected as network interfaces. If the first connection interface 4 is a female network interface connector, then the second connection interface 5 corresponds to a male network interface connector. If the first connection interface 4 is a male network interface connector, then the second connection interface 5 corresponds to a female network interface connector. In the simultaneous interpretation digital microphone 10, in order to meet the needs of multiple devices working together, each simultaneous interpretation digital microphone 10 is specially equipped with two connection interfaces, namely the first connection interface 4 and the second connection interface 5. When it is necessary to connect two adjacent simultaneous interpretation digital microphones 10, a specific connection method is adopted: the first connection interface 4 on one simultaneous interpretation digital microphone 10 is connected to the second connection interface 5 on the other simultaneous interpretation digital microphone 10. The electrical connection is achieved through the internal circuit of the interface, enabling the two simultaneous interpretation digital microphones 10 to exchange and transmit data, such as audio signals and control commands, thereby realizing functions such as cascading expansion and synchronous operation, improving the usage effect and flexibility of the wired daisy-chain simultaneous interpretation digital device.

[0067] like Figure 4 As shown, in one embodiment of this application, a pull-up resistor for preventing signal interference is also connected between the network transceiver U96 and the main control chip U10. The network transformer U4 includes a crystal oscillator X1 and a filter capacitor for filtering out noise frequencies from the crystal oscillator X1.

[0068] It should be noted that an additional pull-up resistor is added to the connection architecture between the network transceiver U96 and the main control chip U10. The main function of this pull-up resistor is to prevent signal interference and ensure the stability and accuracy of signal transmission. In addition, the network transformer U4 includes a crystal oscillator X1 and is equipped with a filter capacitor specifically designed to filter out the noise frequencies generated by the crystal oscillator X1, thereby improving the quality of the network signal.

[0069] like Figure 4As shown in this embodiment, pins 1, 2, 3, 4, 17, 18, and 24 of the audio acquisition chip U14 are connected to pins 55-62 of the main control chip U10 for encoding. Pins 7 and 11 of the audio acquisition chip U14 are connected to capacitors C500 and C154 for filtering.

Pin 21 of the audio acquisition chip U14 is connected to capacitors C136 and C142 for power filtering. Pin 22 of the audio acquisition chip U14 is connected to capacitors C93 and C135 for power filtering. Interface P10 connects to the touchscreen. Pins 1 and 6 of interface P10 are power supply pins, and pins 7-20 are data pins. The touch pins connect to pins 21-23 and 35-45 of the main control chip U10 for display and control. Interface P2 is the volume + / - adjustment button, connected to pins 15 and 16 of the main control chip U10 for control. Interface J1 is a headphone jack connected to pin 25 of the main control chip U10 for audio output. The main control chip U10 has a built-in DAC decoding function, allowing users to select their own voice or a translator's voice via the touchscreen. Pins 1, 13, 19, 32, 48, and 64 of the main control chip U10 are power supply pins, requiring a +3.3V voltage. Switch S2 connects to the main control chip U10 to control the microphone switch. Network transceiver U96 is a control data and audio network transceiver. It connects to the main control chip U10 to process audio data, and ultimately achieves a daisy-chain connection with the host and digital microphone via network transformer U4. Pins 2-11 of the main control chip U10 are connected to pins 9, 10, 11, 15, 16, 17, 20, 21, and 26 of the network transceiver U96 for control processing; pins 3-6 of the main control chip U10 are connected to the output of network transformer U4 to pins P6 and P7. Pin 1 of the network transceiver U96 is the reset pin, connected to ground via resistor R106; pins 2, 7, 29, and 30 of the network transceiver U96 are power supply pins. The network transceiver U96 is grounded through capacitors C53, C89, and C90, which act as power supply filters. The network transceiver U96 is connected to a 3.3V power supply via resistors R29, R30, and R31. Resistors R29, R30, and R31 are pull-up resistors to prevent data signal interference. Pin 28 of the network transceiver U96 is connected to resistor R72 to ensure a stable pull-down to ground. Pins 31 and 32 of the network transceiver U96 are connected to crystal oscillator X1, providing a stable frequency to the chip.
