Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this utility model shall have the ordinary meaning as understood by those skilled in the art to which this utility model pertains.

[0018] First, let's analyze some of the terms used in this utility model: Audio source devices: Audio source devices are devices that can generate or output audio signals, such as music players, computers, mobile phones, game consoles, etc. They use built-in audio processing circuits or software to convert digital or analog audio data into signals that can be played by audio output devices such as speakers and headphones, so that users can hear sound.

[0019] Audio Adapter: An audio adapter is a device used to connect and convert audio signals. It can convert and adapt audio signals of different formats or interfaces to ensure compatibility between audio devices and the stability of signal transmission. For example, it can convert digital audio signals to analog audio signals, or convert audio signals with different interfaces, thereby achieving seamless connection and high-quality audio transmission between audio devices.

[0020] Receiving equipment: Receiving equipment refers to devices used to receive and process audio signals from audio source devices or transmission devices and convert them into audible sound, such as headphones, speakers, and power amplifiers. They use built-in audio processing circuits or decoders to decode, amplify, and optimize digital or analog audio signals to ensure high-quality audio signal reproduction and playback.

[0021] In related technologies, such as Figure 1 As shown, Figure 1 This is a flowchart illustrating the signal transmission process of an audio signal transmission system in related technologies. In these technologies, a signal generation device generates an analog audio signal and transmits it to a transmitter via a 3.5mm audio input / output jack. The transmitter has a 3.5mm audio input / output plug connected to the 3.5mm audio input / output jack. Upon receiving the analog audio signal, the transmitter converts it into a digital audio signal via analog-to-digital conversion and transmits it wirelessly to a signal receiving device. Finally, the signal receiving device receives the digital audio signal from the transmitter using a communication protocol with the transmitter. This method, which directly transmits the analog audio signal to the transmitter via the signal generation device, is susceptible to electromagnetic interference and has weak anti-interference capabilities. Furthermore, transmitting the analog audio signal via the 3.5mm audio input / output plug and 3.5mm audio input / output jack can limit resolution and dynamic range, leading to sound quality distortion.

[0022] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an audio signal transmission system. An analog audio signal is generated by an audio source device, and then converted into a digital audio signal through analog-to-digital conversion within the audio source device. This digital audio signal is then sent to an audio signal adapter device. The audio signal adapter device processes the digital audio signal by adjusting its gain and switching, and then sends the processed digital audio signal to an audio signal receiving device. This ensures that the audio signal received by the receiving device is a digital signal, thereby improving the anti-interference capability and stability of the audio signal during transmission and resulting in more faithful sound quality.

Furthermore, the audio signal receiving module receives the digital audio signal sent by the audio signal transmitting module through a communication connection with the audio signal transmitting module.

[0034] like Figure 3 andFigure 4 As shown, in some embodiments, the audio signal transmission module can be a combination of headphones 1 and audio adapter 2, or a combination of an Xbox controller 3 and audio adapter 2, wherein the audio source device can be headphones 1 or an Xbox controller 3, and the audio signal adapter device can be audio adapter 2. Further, by Figure 3 It can be seen that the audio adapter 2 communicates with the headphones 1 via Bluetooth or 2.4G wireless connection. Figure 4 As can be seen, the audio adapter 2 communicates with the Xbox controller 3 via the 12S and 12C interfaces, and can also communicate with the Xbox controller 3 via the Type-C or Universal Serial Bus interface. It should be noted that the communication interface of the audio adapter 2 can be selected according to the communication interface of the Xbox controller 3 itself.

[0035] like Figure 5As shown, in some embodiments, the audio adapter 2 is provided with an I2S interface 4, an I2C interface 5, and a Universal Serial Bus (USB) interface 6. The combination of I2S interface 4, I2C interface 5, and USB interface 6 constitutes the wired communication component of the audio adapter 2. It should be noted that the wireless communication component can be a wireless communication chip built into the audio adapter 2, which can perform Bluetooth or 2.4G wireless communication. Further, the combination of I2S interface 4 and I2C interface 5 is the audio control interface of the audio adapter 2. This combination is used to transmit audio digital signals within the audio adapter 2 and to configure the transmission parameters of the audio digital signals. USB interface 6 is the audio control interface, data, and power interface of the audio adapter 2. USB interface 6 can also be used to transmit audio digital signals within the audio adapter 2 and can also provide power to the audio adapter 2 to ensure its normal operation. It should be noted that, to reduce the operating conditions of the audio adapter 2, the audio adapter 2 can also be powered by a built-in battery to transmit audio digital signals. Secondly, the 12S interface 4 is the audio digital interface of the audio adapter 2, used to obtain high-quality digital audio signals from the Xbox controller 3. The 12C interface 5 is the signal transmission control interface of the audio adapter 2, used to control and configure the relevant parameters of audio digital signal transmission within the audio adapter 2. It's important to note that a communication connection is required between the 12S interface 4 and the 12C interface 5 to ensure that the digital audio signals obtained from the Xbox controller 3 can be transmitted within the audio adapter 2. Finally, both the 12S interface 4 and the 12C interface 5 are located on the same side of the audio adapter 2 for easy alignment with the communication interface of the Xbox controller 3. A certain distance is maintained between the 12S interface 4 and the 12C interface 5 to avoid signal interference. Furthermore, the Universal Serial Bus interface 6 can be located on the same side of the 12S interface 4 and the 12C interface 5, or on different sides.

[0036] It is also important to know that the audio adapter 2 has multiple functions, including sound amplification, sound reduction, one-click mute, and audio channel switching. The sound amplification function is used to increase the gain of the audio digital signal received by the audio adapter 2 to amplify the audio sound. The sound reduction function is used to decrease the volume of the audio digital signal received by the audio adapter 2. Therefore, the sound amplification and sound reduction functions are equivalent to the audio signal gain module in the audio signal processing unit. The one-click mute function cuts off the audio digital signal input to the audio adapter 2 to achieve the audio mute effect. Therefore, the one-click mute function is equivalent to the audio signal cutting component in the audio signal processing unit. The audio channel switching function adjusts the communication frequency of the audio adapter 2 to determine the audio digital signal to be transmitted, thereby achieving the selection of the audio signal to be received. Therefore, the audio channel switching function is equivalent to the frequency synthesis component in the audio signal processing unit.

[0037] like Figure 6 As shown, headphones 1, audio adapter 2, and Xbox controller 3 can form an audio signal transmission system. Both headphones 1 and Xbox controller 3 can serve as audio source devices, audio adapter 2 as audio signal adapter, and both headphones 1 and Xbox controller 3 as audio signal receivers. Specifically, when headphones 1 are used as the audio source, they collect audio through a microphone, generate an analog audio signal, and then convert this analog signal into a digital audio signal. The digital audio signal is then sent to audio adapter 2. Audio adapter 2 performs gain processing, cutoff processing, and communication channel control on the digital audio signal to achieve digital signal processing. Finally, audio adapter 2 receives the digitally processed audio signal... The audio signal is sent to the Xbox controller 3. The Xbox controller 3 receives the digitally processed audio signal through the signal receiving unit and performs digital-to-analog conversion on the digital audio signal to obtain an analog audio signal. When the Xbox controller 3 is used as an audio source device, the Xbox controller 3 generates an analog audio signal and then converts the analog audio signal back into a digital audio signal. Further, the Xbox controller 3 sends the digital audio signal to the audio adapter 2. The audio adapter 2 performs gain processing, cut-off processing, and communication channel control on the digital audio signal to achieve digital signal processing of the digital audio signal. Next, the audio adapter 2 sends the digitally processed audio signal to the headset 1. The headset 1 receives the digitally processed audio signal through the signal receiving unit and performs digital-to-analog conversion on the digital audio signal to obtain an analog audio signal.

[0038] This invention proposes an audio signal transmission system. An analog audio signal is generated by an audio source device and converted into a digital audio signal through analog-to-digital conversion. This digital audio signal is then sent to an audio signal adapter. The audio signal adapter processes the digital audio signal by adjusting its gain and switching, and sends the processed digital audio signal to an audio signal receiving device. This ensures that the audio signal received by the receiving device is a digital signal, thereby improving the anti-interference capability and stability of the audio signal during transmission and resulting in higher fidelity sound quality.

[0039] This utility model also proposes a courier flow code identification system, including a flow code information storage database and an audio signal transmission system as described above, which can improve the anti-interference ability during audio signal transmission and make the sound quality more authentic.
