Description

Technical Field

[0002] An audio conferencing system is a system that enables remote audio communication. It allows two or more individuals or groups in different locations to transmit sound to each other via transmission lines and multimedia equipment, achieving real-time and interactive communication to accomplish meeting objectives. In practical applications, traditional audio conferencing systems primarily involve directly connecting the audio system to the conferencing terminal or having the terminal send the audio to the conferencing system. The conferencing terminal then encodes the audio and transmits it over the network to the remote location for decoding and retransmission.

[0003] In practical applications, traditional audio conferencing systems require data cables to connect to the terminals, with a maximum transmission distance of less than 5 meters and complex cabling. If the distance between the conferencing terminal and the audio system exceeds this range, additional extension cables or signal amplifiers are needed, which not only increases costs but may also introduce signal attenuation and interference problems. Furthermore, traditional audio conferencing systems often lack sufficient flexibility; once the locations of the conferencing terminals and audio systems are determined, it is difficult to move or adjust them, limiting the diversity and flexibility of meeting scenarios. Therefore, an audio conferencing component is needed to solve the problems of complex cabling, short transmission distance, and poor flexibility of current audio equipment. Utility Model Content

[0033] To address the above problems, this utility model proposes a wireless conferencing component, such as... Figure 1 As shown, it includes an audio processing circuit 05 and an audio acquisition circuit 01, an audio output circuit 02, a touch button circuit 03, and a first wireless transceiver circuit 04 electrically connected to the audio processing circuit 05.

[0034] Audio acquisition circuit 01 is used to acquire audio and convert the audio into a digital audio signal for output.

[0035] The audio output circuit 02 is used to receive the analog sound signal output by the audio processing circuit 05, convert the analog sound signal into a digital sound signal, process the digital sound signal, and output it to the speaker to produce sound.

[0036] The touch button circuit 03 is used to transmit the operation signal corresponding to the operated button to the audio processing circuit 05 when the button is touched by the user.

[0037] The first wireless transceiver circuit 04 is used for communication between the audio processing circuit 05 and the terminal device.

[0038] The audio processing circuit 05 is used to process the digital audio signals acquired by the audio acquisition circuit 01 and output them to the audio output circuit 02 or send them to the terminal device through the first wireless transceiver circuit 04; process the digital audio signals received by the first wireless transceiver circuit 04 and output them to the audio output circuit 02; and respond to and execute the operation signals of the touch button circuit 03.

[0039] More specifically, the main function of the audio acquisition circuit 01 is to convert sound signals (usually analog signals) into digital audio signals. This process typically includes the following steps: The sound signal enters the audio acquisition circuit 01 through an audio input device such as a microphone. The analog-to-digital converter chip in the audio acquisition circuit 01 periodically samples the input analog audio signal and converts it into a binary digital signal. The digital audio signal after analog-to-digital conversion is then output to the subsequent audio processing circuit 05 for further processing.

[0040] The main function of the touch button circuit 03 is to enable users to control the audio system through touch operations. When a user touches a button, the touch button circuit 03 transmits the operation signal corresponding to the operated button to the audio processing circuit 05. The touch button circuit 03 identifies the touch operation by detecting changes in current or capacitance generated by the user's touch, converts the detected touch signal into an operation signal that the audio processing circuit 05 can recognize, and transmits the operation signal to the audio processing circuit 05 to execute the corresponding control operation.

[0041] The primary function of the first wireless transceiver circuit 04 is to enable wireless communication between the audio processing circuit 05 and the terminal device. The audio processing circuit 05 modulates the audio data to be transmitted onto a high-frequency carrier wave to form a wireless signal. The modulated wireless signal is transmitted through an antenna, and the terminal device receives the transmitted wireless signal through its associated antenna equipment. The terminal device demodulates the received wireless signal to reconstruct the original audio data. The terminal device then processes the demodulated audio data, such as decoding and amplifying it. Simultaneously, the audio processing circuit 05 can also receive wireless signals sent by the terminal device in the same manner, thereby acquiring the audio signals sent by the terminal device.

[0042] When the audio processing circuit 05 receives the digital audio signal output by the audio acquisition circuit 01 or the digital audio signal received by the wireless transceiver circuit, the audio processing circuit 05 performs audio encoding, audio decoding, audio and video format conversion and 3A algorithm processing on the digital audio signal to improve sound quality and enhance the dynamic range and clarity of the signal.

[0043] Audio encoding is the process of converting raw audio data into a more efficient and compact format, aiming to reduce storage space requirements or improve transmission efficiency. Common audio encoding formats include MP3, AAC, WAV, and FLAC. Audio decoding, on the other hand, is the process of restoring compressed audio data to its original form. Audio encoding compresses and encodes processed digital audio signals, reducing the space and time required for storage and transmission, and allows for decoding from storage when needed. The decoded digital audio signal is then converted to the desired format before undergoing 3A algorithm processing.

[0044] The 3A algorithm processing includes echo cancellation (AEC), noise reduction (ANS), and automatic gain control (AGC). Echo cancellation (AEC) uses an adaptive filter to cancel echoes, achieving better received signal quality. In communication applications, especially video conferencing systems and hands-free voice calls, the presence of echoes can severely affect call quality.

[0045] Animated Noise Reduction (ANS) is a process that identifies and eliminates background noise in audio. Background noise is divided into balanced noise and transient noise. Balanced noise has a stable spectrum, while transient noise has a small spectral energy variance. Utilizing these characteristics, noise can be eliminated by adding an inverse waveform processing layer to the audio data. Through the ANS algorithm, background noise in the user's environment can be suppressed to the greatest extent possible, improving speech clarity.

[0046] Automatic gain control (AGC) automatically adjusts the amplifier's gain to maintain a constant average level of the output signal. The AGC algorithm dynamically adjusts the gain based on the strength of the input signal to avoid excessively loud or soft volumes. This is especially important in scenarios such as audio / video calls and voice chat rooms, ensuring that the sound heard by the user remains within a comfortable volume range.

[0047] The audio processing circuit 05 transmits the processed digital audio signal to the terminal device via the first wireless transceiver circuit 04, realizing wireless audio transmission or output to the audio output circuit 02 to drive the speaker to produce sound. Simultaneously, the audio processing circuit 05 responds to and executes operation signals from the touch button circuit 03, such as adjusting volume, switching songs, and answering calls. The audio processing circuit 05 of this invention employs an audio processing SOC (System on Chip).

[0048] The audio output circuit 02 receives the analog sound signal output by the audio processing circuit 05, converts the analog sound signal into a digital sound signal, processes the digital sound signal, and outputs it to the speaker to produce sound. Typically, the audio output circuit 02 includes an analog-to-digital converter (ADC) and a digital signal processing circuit. The ADC converts the analog signal into a digital signal. It should be noted that this step is not common in practical applications because the speaker requires an analog signal to drive it.

[0049] Therefore, in subsequent steps, the digital signal needs to be converted back to an analog signal to drive the speaker. A digital signal processing circuit is used to further process the digital signal, such as equalization, filtering, and volume adjustment (this step requires converting the digital signal back to an analog signal). The processed analog signal is amplified by an amplifier, and the amplified signal is sent to the speaker to produce sound.

[0050] This invention allows the audio processing circuit 05 to accurately capture audio signals through the built-in audio acquisition circuit 01, and then send these signals to the terminal device, or play them directly through the audio output circuit 02. Simultaneously, the audio processing circuit 05 can receive audio from the terminal device through the wireless transceiver circuit. The wireless transceiver circuit eliminates the constraints of wired connections, improving communication flexibility and range. The wireless design simplifies wiring and reduces installation and maintenance costs. Furthermore, this invention is specially equipped with a touch button circuit 03 for convenient user adjustment of audio output.

[0051] In one embodiment, such as Figure 1 As shown, the audio acquisition circuit 01 includes a main microphone and an extended microphone. The output of the main microphone is electrically connected to the audio processing circuit 05. The extended microphone and the audio processing circuit 05 transmit data through an RS485 transmitting circuit and an RS485 receiving circuit. The RS485 transmitting circuit is located inside the extended microphone, and the RS485 receiving circuit is electrically connected to the audio processing circuit 05.

[0052] The main microphone is the core component of the audio acquisition system, responsible for directly capturing sound signals. Its output is directly electrically connected to the audio processing circuit 05, meaning the captured sound signal can be transmitted to the audio processing circuit 05 for subsequent processing without delay. The extended microphone is used to enhance the range of audio acquisition or capture sound from a specific direction. Unlike the main microphone, the extended microphone is not directly connected to the audio processing circuit 05; instead, it transmits data via the RS485 communication protocol.

[0053] The audio signal from the extended microphone is converted into a differential signal via its built-in RS485 transmitting circuit and transmitted via the RS485 bus to the RS485 receiving circuit near the audio processing circuit 05. The RS485 receiving circuit receives the differential signal from the extended microphone and decodes it into a digital audio signal. The audio processing circuit 05 receives the digital audio signals from both the main microphone and the extended microphone and performs subsequent processing, such as encoding, decoding, and format conversion. The extended microphone supports a maximum transmission distance of 5 meters using the RS485 protocol. This design increases the pickup radius of the audio system and enhances the sound quality, achieving optimal sound performance in large conference rooms.

[0054] In one embodiment, multiple main microphones are provided, arranged in a circular array. The circular array of microphones exhibits good consistency, meaning that each microphone has similar performance in capturing sound signals, thus ensuring the stability and accuracy of the audio signal. Simultaneously, this array also possesses good anti-interference capabilities, effectively suppressing environmental noise and interference signals, and improving the signal-to-noise ratio of the audio signal.

[0055] In one embodiment, the audio acquisition circuit 01 converts the audio into a digital audio signal in PDM data format and outputs it. The digital audio signal is transmitted in PDM format. PDM format represents the intensity of the audio signal through pulse density and is characterized by simplicity, efficiency, and ease of implementation.

[0056] In one embodiment, such as Figure 1 As shown, the audio output circuit 02 includes an ADC conversion circuit 51, a digital processing circuit, and a signal amplification circuit. The input terminal of the ADC conversion circuit 51 is electrically connected to the audio processing circuit 05, and the output terminal is electrically connected to the input terminal of the digital processing circuit. The signal amplification circuit is electrically connected to the digital processing circuit, and the output terminal is electrically connected to the speaker.

[0057] The ADC conversion circuit is used to convert the analog sound signal output by the audio processing circuit 05 into a digital sound signal; this step is implemented by an ADC (Analog to Digital Converter), which receives data from the audio processing circuit 05 in I2S format.

[0058] The digital processing circuit is used to perform frequency division, equalization, and gain processing on the digital audio signal output by the ADC conversion circuit 51. Frequency division divides the digital audio signal into different frequency ranges and processes them separately, which helps to ensure that the sound in each frequency range is properly processed, thereby improving the overall sound quality.

[0059] An equalizer (EQ) is used to adjust the gain of an audio signal across different frequency ranges to improve sound quality and meet specific listening preferences. By adjusting EQ settings, you can enhance or reduce the sound of specific frequencies, making the overall sound quality more balanced and harmonious.

[0060] Gain processing adjusts the amplitude of the audio signal to ensure it remains at an appropriate level during transmission and amplification. Gain processing helps prevent signal overload or distortion, thus improving overall sound quality. Digital processing circuitry precisely controls various parameters of the audio signal, enabling fine-tuning and optimization of sound quality. Since speakers require analog signals, this step also requires converting the digital signal to an analog signal.

[0061] The signal amplification circuit amplifies the digital audio signal processed by the digital processing circuit and outputs it to the speaker. The amplification circuit ensures that the audio signal has sufficient power to drive the speaker, thereby producing a clear and loud sound.

[0062] In one embodiment, the loudspeaker includes a high-frequency loudspeaker and a low-frequency loudspeaker.

[0063] High-frequency loudspeakers are primarily responsible for reproducing the high-frequency components of audio signals, such as clear details in vocals, sharp timbre of instruments, and high-frequency overtones in music. High-frequency loudspeakers typically feature smaller diaphragms and lighter voice coils to enable a faster response to high-frequency signals while minimizing distortion.

[0064] Low-frequency loudspeakers are primarily responsible for reproducing the low-frequency components of audio signals, such as rhythm, drum beats, and bass guitar in music. Low-frequency loudspeakers typically have large diaphragms and heavy voice coils to generate sufficient low-frequency energy and a deep sound. They are usually capable of handling higher power and have high sensitivity to ensure clear, powerful sound in the low-frequency range.

[0065] In this embodiment, the audio output module is equipped with high and low frequency speakers and a resonant cavity design. The front-end audio processing module outputs dual-channel audio data for EQ tuning, frequency division, and gain configuration, so that the high and low frequency speakers can perform at their best. The combination of high frequency and low frequency speakers can bring a more balanced and richer sound performance, making the bass deep, the treble clear, and the sound clear and natural, making voice communication efficient and natural.

[0066] In one embodiment, the touch button circuit 03 employs a 5-channel touch button. Each button corresponds to an independent function, facilitating quick user identification and operation. The 5-channel touch button includes functions for hanging up an audio conference, answering an audio conference, muting, increasing volume, and decreasing volume. Meanwhile, the extended microphone uses a single-channel touch button.

[0067] In one embodiment, the wireless conferencing component further includes a dongle circuit, and the audio processing circuit 05 wirelessly transmits data to the terminal device via the first wireless transceiver circuit 04 and the dongle circuit. A dongle circuit typically refers to a circuit system in a small hardware device that can be attached to a computer's parallel port, serial port, or USB interface.

[0068] In one embodiment, the dongle circuit includes a second wireless transceiver circuit 07 and a USB interface transmission circuit 08, wherein the second wireless transceiver circuit 07 is electrically connected to the terminal device through the USB interface transmission circuit 08.

[0069] There is a bidirectional sound transmission direction between the dongle circuit and the audio processing circuit 05. In the sound acquisition direction, the data acquired by the audio acquisition circuit 01 is sent to the first wireless transceiver circuit 04 after passing through the audio processing module. The first wireless transceiver circuit 04 and the second wireless transceiver circuit 07 transmit the data to the USB interface transmission circuit 08, and then the USB interface transmission circuit 08 uploads the data to the external terminal device for transmission.

[0070] In the direction of sound playback, the audio data transmitted from the terminal device is sent to the audio processing circuit 05 for processing through the second wireless transceiver circuit 07 and the first wireless transceiver circuit 04. After audio output current frequency division, EQ adjustment, and gain adaptation, it is sent to the Amplifier for amplification of small signals to drive the back-end speaker.

[0071] The first wireless transceiver circuit 04 and the second wireless transceiver circuit 07 are paired by default and can be automatically connected and used upon power-up. They are simple, clear and efficient to use, and the maximum straight-line transmission distance can reach 30m.

[0072] In one embodiment, the wireless conferencing component further includes a data buffer circuit 06 electrically connected to the audio processing circuit 05;

[0073] The data buffer circuit 06 is used to store the digital audio signals acquired by the audio acquisition circuit 01 and the digital audio signals received by the first wireless transceiver circuit 04. The audio acquisition circuit 01 typically includes sound sensors such as microphones, which convert sound into analog signals, and then convert them into digital audio signals via an analog-to-digital converter. The data buffer circuit 06 receives these digital audio signals and temporarily stores them for further processing by subsequent digital signal processing circuits or audio codecs.

[0074] The first wireless transceiver circuit 04 is responsible for receiving digital audio signals from other wireless audio devices (such as wireless microphones, wireless audio transmitters, etc.). These received signals are also stored by the data buffer circuit 06 for synchronization, mixing, or other processing with the signals acquired by the audio acquisition circuit 01.

[0075] In one embodiment, the wireless conferencing component further includes an LED light matrix circuit and an encryption module. The LED light matrix is ​​a 36*36*36 RGB tri-color square light strip, primarily displaying: red for mute, green for connection, and a running light effect for power-on. The encryption module mainly encrypts the audio algorithms of the audio processing module to protect the confidentiality and integrity of data, ensuring product security.
