The target switch 4 is connected to the wireless cascade module 2 in the second state position. The target switch 4 is connected to the wired cascade module 3 in the second state position. The two ends of the target chip 5 are connected to the control module 1 and the target switch 4 respectively. The control module 1 is connected to the information identification module 31 and obtains the target information. If the target information is in wireless transmission mode, a first signal is sent to the target switch 4 to switch the target switch 4 to the first state position. The target chip 5 is used for modulation or demodulation of wireless signals in wireless transmission mode. If the target information is in wired transmission mode, a second signal is sent to the target switch 4 to switch the target switch 4 to the second state position. The target chip 5 is used for modulation or demodulation of wired signals in wired transmission mode.

[0051] Specifically, in order to control the signal transmission between the electronic device and the target device 6, this application provides a control module 1. The control module 1 can be an MCU (Microcontroller Unit) or SOC (System on Chip) in the electronic device. The control module 1 can communicate with the information identification module 31 in the wired cascade module 3 to obtain the target information of the target device 6, or communicate with the target switch 4 to control the target switch 4 to be in the first state position or the second state position. It can also be connected to the target chip 5 to transmit low-frequency wireless signals or low-frequency wired signals to the target chip 5 so that the target chip 5 modulates the signals, or receive the low-frequency wireless signals or low-frequency wired signals obtained by demodulation by the target chip 5.

[0052] To achieve wireless signal transmission, this application includes a wireless cascading module 2. When the target switch 4 is controlled by the control module 1 to the first state position, the wireless cascading module 2 operates to achieve wireless signal transmission to the target device 6. The wireless cascading module 2 can be an antenna, a wireless local area network communication module, a Bluetooth module, etc., and is not specifically limited thereto.

[0053] This application provides a wired cascading module 3 to meet the insertion requirements of the target device 6. Furthermore, to enable the cascading system to dynamically adapt based on the signal transmission modes supported by the target device 6, the wired cascading module 3 is equipped with an information identification module 31. This module automatically identifies the target information of the inserted target device 6, and subsequently identifies the wired or wireless transmission modes supported by the target device 6. Under the control of the control module 1, the signal transmission can switch between wired and wireless transmission modes. The wired cascading module can be a USB (Universal Serial Bus) module, a Thunderbolt (Intel High Speed ​​Interface) module, etc., and the information identification module 31 can be a VDM (Vendor Defined Messages) module, an RFID (Radio Frequency Identification) module, etc.

[0054] To simplify the signal link switching process and reduce system complexity, this application includes a target switch 4. The target switch 4 has a first state position and a second state position that can be switched under the control of the control module 1. In the first state position, the target switch 4 is communicatively connected to the wireless cascade module 2, and in the second state position, it is communicatively connected to the wired cascade module 3. By using the target switch 4, this application simplifies the signal link switching process between wired and wireless connections, thereby avoiding interference during signal link switching and improving signal transmission stability. In the cascade system of this application, the target switch 4 is connected to the target chip 5 on one side, and needs to be connected to either the wireless cascade module 2 or the wired cascade module 3 in either of the two state positions on the other side. In one embodiment, the target switch 4 can be a high-frequency SPDT (Single Pole Double Throw switch) to meet the switching and signal connection requirements between the two state positions.

[0055] To reduce the number of protocols and chips required for wireless or wired signal transmission, this application includes a target chip 5 that can be multiplexed in different wired or wireless transmission modes. This allows for dynamic modulation or demodulation of wired or wireless signals during transmission, depending on the mode. Specifically, when the target switch 4 is switched to the first state, the target chip 5 is used for modulation or demodulation of wireless signals in wireless transmission mode; when the target switch 4 is switched to the second state, the target chip 5 is used for modulation or demodulation of wired signals in wired transmission mode. The target chip 5 can be an RFIC (Radio Frequency Integrated Circuit) chip or an RFTC (Radio Frequency Transceiver Chip), etc. Furthermore, when the target device 6 is not inserted into the wired cascade module 3, if it requires signal transmission, this application can also control the target switch 4 to be in the first state through the control module 1 to enable the wireless cascade module 2. In this case, the wireless signal of the target device 6 can be transmitted through the wireless cascade module 2.

[0056] To demonstrate the application of the cascaded system in signal transmission, in one embodiment, in the usage scenario of a smart furniture system, when the target device 6 is a wired speaker, the user inserts the wired speaker into the wired cascade module 3. The information recognition module 31 automatically recognizes that the inserted wired speaker supports wired transmission mode. After the control module 1 obtains the corresponding target information, it sends a second signal to the target switch 4 to switch the target switch 4 to the second state position. The target chip 5 modulates the wired signal in the wired transmission mode. Specifically, when the wired speaker is the receiving end, the control module 1 sends a low-frequency wired signal to the target chip 5. The target chip 5 modulates the low-frequency wired signal into a high-frequency wired signal, which is then output to the wired speaker through the target switch 4 and the wired cascade module 3.

[0057] In one embodiment, in a smart furniture system usage scenario, when the target device 6 is a Bluetooth speaker, the user inserts the Bluetooth speaker into the wired cascade module 3. The information identification module 31 automatically identifies that the inserted Bluetooth speaker supports wireless transmission mode. After the control module 1 obtains the corresponding target information, it sends a first signal to the target switch 4 to switch the target switch 4 to the first state position. The target chip 5 modulates the wireless signal in the wireless transmission mode. Specifically, when the Bluetooth speaker acts as the receiver, the control module 1 sends a low-frequency wireless signal to the target chip 5. The target chip 5 modulates the low-frequency wireless signal into a high-frequency wireless signal, which is then output to the Bluetooth speaker through the target switch 4 and the wireless cascade module 2.

The control module 1 can be adjusted according to the quality of the wired or wireless signals, the transmission environment of the smart speaker, and the user's transmission needs, so that the target switch 4 can switch between a first state position and a second state position by sending a first signal or a second signal.

[0059] In one embodiment, in a recording studio setting, when the target device 6 is a wired microphone, the user inserts the wired microphone into the wired cascade module 3. The information recognition module 31 automatically recognizes that the inserted wired microphone supports wired transmission mode. After the control module 1 obtains the corresponding target information, it sends a second signal to the target switch 4 to switch the target switch 4 to the second state position. The target chip 5 demodulates the wired signal in wired transmission mode. Specifically, when the wired microphone is used as a transmitter, the wired microphone transmits a high-frequency wired signal through the wired cascade module 3, which is output to the target chip 5 via the target switch 4. The target chip 5 demodulates the high-frequency wired signal into a low-frequency wired signal and sends it to the control module 1.

[0060] In one embodiment, in a recording studio setting, when the target device 6 is a wireless microphone, the user inserts the wireless microphone into the wired cascade module 3. The information identification module 31 automatically identifies that the inserted wireless microphone supports a wireless transmission mode. After the control module 1 obtains the corresponding target information, it sends a first signal to the target switch 4 to switch the target switch 4 to the first state position. The target chip 5 modulates the wireless signal in the wireless transmission mode. Specifically, when the wireless microphone acts as a receiver, the control module 1 sends a low-frequency wireless signal to the target chip 5. The target chip 5 modulates the low-frequency wireless signal into a high-frequency wireless signal, which is then output to the wireless microphone via the target switch 4 and the wireless cascade module 2.

[0061] In one embodiment, when the target device 6 is a smart microphone that supports both wired and wireless transmission modes, that is, when the target information can be transmitted in either wired or wireless mode, the smart microphone can transmit wired signals through the wired cascade module 3 or wireless signals through the wireless cascade module 2. The control module 1 can be adjusted according to the quality of the wired or wireless signals, the transmission environment of the smart microphone, and the user's transmission needs, so that the target switch 4 can switch between a first state position and a second state position by sending a first signal or a second signal.

[0062] This application provides a cascading system, including a control module 1, a wireless cascading module 2, a wired cascading module 3, a target switch 4, and a target chip 5. The wireless cascading module 2 is used for wireless signal transmission. The wired cascading module 3 is communicatively connected to the control module 1 and is used for wired signal transmission. The wired cascading module 3 includes an information identification module 31, which is used to identify target information of a target device 6 inserted into the wired cascading module 3. The target information includes the wired transmission mode or wireless transmission mode supported by the target device 6. The target switch 4 is communicatively connected to the control module 1 and has a switchable first state bit and a second state bit. In the first state bit, the target switch... 4. The target switch 4 is connected to the wireless cascade module 2 in the second state position. The two ends of the target chip 5 are connected to the control module 1 and the target switch 4 respectively. The control module 1 is connected to the information identification module 31 and obtains the target information. If the target information is in wireless transmission mode, a first signal is sent to the target switch 4 to switch the target switch 4 to the first state position. The target chip 5 is used for modulation or demodulation of wireless signals in wireless transmission mode. If the target information is in wired transmission mode, a second signal is sent to the target switch 4 to switch the target switch 4 to the second state position. The target chip 5 is used for modulation or demodulation of wired signals in wired transmission mode. This application, through the information identification module 31 set in the wired cascade module 3, can automatically identify the target information of the inserted target device 6, and then identify the wired or wireless transmission mode supported by the target device 6. Under the control of the control module 1, the signal transmission can be switched between the wired and wireless transmission modes. Furthermore, the target chip 5 set in this application can dynamically modulate or demodulate the wired or wireless signals during transmission according to different transmission modes, realizing the multiplexing of the target chip 5 in different transmission modes. Compared with the traditional solution of setting different protocols and chips for wireless cascade and wired cascade respectively, the complexity of the system is greatly simplified. At the same time, through the setting of the target switch 4, this application simplifies the switching process of the signal link between wired and wireless, thereby avoiding interference during the signal link switching process and improving the stability of signal transmission.

[0063] like Figure 1 and Figure 2As shown, in some embodiments, the target chip 5 has a switchable master device mode and a slave device mode. In master device mode, the target chip 5 is used to initiate a signal transmission request with the target device 6. In slave device mode, the target chip 5 is used to respond to the signal transmission request of the target device 6. The control module 1 includes a first configuration module 11, which is communicatively connected to the target chip 5 and the information identification module 31. The target information also includes the active transmission mode or passive transmission mode supported by the target device 6. If the target information is in active transmission mode, the first configuration module 11 sends a first configuration instruction to the target chip 5 to switch the target chip 5 to slave device mode. If the target information is in passive transmission mode, the first configuration module 11 sends a second configuration instruction to the target chip 5 to switch the target chip 5 to master device mode. In active transmission mode, the target device 6 can initiate a signal transmission request. In passive transmission mode, the target device 6 can respond to the signal transmission request initiated by the target chip 5.

[0064] Specifically, the target chip 5 in the cascade system of this application has a switchable master device mode and slave device mode, so that the target chip 5 can initiate a signal transmission request to the target device 6 and also respond to the signal transmission request of the target device 6, thereby establishing a two-way communication mechanism. This allows the electronic device provided by this application in the device cascade system to flexibly switch the signal transmission path with the target device 6, thereby improving the flexibility and compatibility of the electronic device.

[0065] To enable the switching of the target chip 5 between master device mode and slave device mode, the control module 1 of this application includes a first configuration module 11. The first configuration module 11 sends a first configuration command or a second configuration command to the target chip 5 to achieve dynamic configuration of the target chip 5 between master device mode and slave device mode. The first configuration module 11 is communicatively connected to the information identification module 31. When the target device 6 is inserted, the target information that can be obtained by the control module 1 also includes the active transmission mode or passive transmission mode supported by the target device 6. This allows the cascaded system to configure the target chip 5 according to the transmission requirements of the target device 6 through the first configuration module 11, so as to meet the smooth communication between the target chip 5 and the target device 6, achieve the matching of signal transmission requests, and improve the overall reliability of the cascaded system.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the control module 1 further includes a second configuration module 12, which is communicatively connected to the target chip 5 and the information identification module 31. The target information also includes the transmission parameters supported by the target device 6. The second configuration module 12 can send a third configuration instruction to the target chip 5 so that the target chip 5 matches the transmission parameters.

[0067] Specifically, in order to improve the quality of signal transmission and the user experience, the control module 1 of this application also includes a second configuration module 12. The second configuration module 12 is communicatively connected to the target chip 5 and the information identification module 31 to obtain the data rate, encoding format, sampling rate and other transmission parameters supported by the target device 6, and sends a third configuration quality to the target chip 5 so that the target signal is adjusted to match the data rate, encoding format, sampling rate and other transmission parameters of the target device 6, so as to avoid signal distortion or delay caused by parameter mismatch, thereby improving the quality of signal transmission and the user experience.

[0068] like Figure 1 and Figure 3 As shown, in some embodiments, the wired cascade module 3 further includes a data transmission interface 32 and a wired transmission channel 33. The data transmission interface 32 is used to insert the target device 6; the target switch 4 is in a second state position, and the wired transmission channel 33 connects the data transmission interface 32 and the target switch 4; the wired cascade module 3 further includes a first detection module 34, which is used to detect the signal quality between the target device 6 and the data transmission interface 32 and generate quality information. The control module 1 sends a first signal or a second signal to the target switch 4 according to the target information and the quality information.

[0069] Specifically, the wired cascade module 3 of this application includes a data transmission interface 32 to provide a physical connection point, enabling the target device 6 to be inserted and identified by the information recognition module 31. The data transmission interface 32 can be of type Type-B, Type-C USB (Universal Serial Bus), Thunderbolt (Intel High Speed ​​Interface), etc., and is not limited to any specific type, as long as it meets the insertion requirements of the target device 6 compatible with the electronic device. The wired cascade module 3 also includes a wired transmission channel 33 as a channel connecting the data transmission interface 32 and the target switch 4, used for wired signal transmission when the target switch 4 is in its second state position and the target information is in wired transmission mode.

[0070] To achieve dynamic adjustment of signal transmission in the cascaded system, the wired cascaded mode in this application further includes a first detection module 34. The first detection module 34 is used to detect the signal quality between the target device 6 and the data transmission interface 32 and generate quality information. The quality information can be characterized as the signal strength, bit error rate, signal-to-noise ratio, jitter, packet loss rate, etc. of wireless or wired signals. The control module 1 can set a signal quality threshold corresponding to the quality information, which may include a signal strength threshold, a bit error rate threshold, a signal-to-noise ratio threshold, a jitter threshold, a packet loss rate threshold, etc. When the signal quality parameters in the quality information exceed the signal quality threshold, the control module 1 can control the target switch 4 based on the quality information detected by the first detection module 34 and the target information.

[0071] In some embodiments, when the target information is in wireless transmission mode, if the wireless signal quality in the quality information exceeds the signal quality threshold, the control module 1 can send a second signal to the target switch 4 to make it be in a second state position, so as to transmit signals to the target device 6 via a wired connection; when the target information is in wireless transmission mode, if the wireless signal quality in the quality information does not exceed the signal quality threshold, the control module 1 continues to send a first signal to the target switch 4; when the target information is in wired transmission mode, if the wired signal quality in the quality information exceeds the signal quality threshold, the control module 1 can send a first signal to the target switch 4 to make it be in a first state position, so as to transmit signals to the target device 6 via a wireless connection; when the target information is in wired transmission mode, if the wired signal quality in the quality information does not exceed the signal quality threshold, the control module 1 continues to send a second signal to the target switch 4.

[0072] like Figure 1 and Figure 3 As shown, in some embodiments, the wired cascaded module 3 further includes a configuration channel pin 35 and a second detection module 36. The configuration channel pin 35 has voltage data, and the second detection module 36 is communicatively connected to the configuration channel pin 35 to acquire the voltage data. The second detection module 36 is used to detect the connection status between the target device 6 and the data transmission interface 32 based on the voltage data and generate connection status information. The control module 1 is communicatively connected to the information identification module 31 based on the connection status information.

[0073] Specifically, this application includes a configuration channel pin 35 to provide voltage data reflecting the physical connection between the target device 6 and the data transmission interface 32. When the target device 6 is not inserted into the configuration channel pin 35, the configuration channel pin 35 is floating or grounded, and the voltage data is 0V. When the target device 6 is inserted, the configuration channel pin 35 connects to the internal circuitry of the target device 6, generating a high-level signal, making the voltage data greater than 0V. When the target device 6 has good contact with the configuration channel pin 35, the voltage data greater than 0V is stable. When the target device 6 has poor contact with the configuration channel pin 35, the voltage data is unstable. To improve the reliability of the cascaded system, this application uses wired cascading. Module 3 is equipped with a second detection module 36. The second detection module 36 can detect the connection status between the target device 6 and the data transmission interface 32 based on the voltage data and generate connection status information. That is, when the voltage data is 0V, the connection status information is not connected; when the voltage data is greater than 0V and stable, the connection status information is stable connected; when the voltage data is greater than 0V but unstable, the connection status information is unstable connected. The control module 1 controls whether to communicate with the information identification module 31 based on the above connection status information, so that no subsequent signal transmission and control are performed when the connection status information is not connected or unstable connected, thereby improving the reliability of the cascaded system.

[0074] like Figure 1 and Figure 4 As shown, in some embodiments, it further includes an impedance matching circuit 7, the two ends of which are respectively connected to the wired cascaded module 3 and the target switch 4, so that the impedance of the target device 6 and the impedance of the wired cascaded module 3 meet the matching relationship.

[0075] Specifically, to improve the quality and stability of signal transmission and reduce signal attenuation and interference caused by impedance mismatch, the cascaded system of this application also includes an impedance matching circuit 7. The two ends of the impedance matching circuit 7 are connected to the wired cascaded module 3 and the target switch 4, respectively, to match the target device 6 with the wired cascaded module 3 through resistor or capacitor parameter matching. This reduces energy loss in the transmission path, lowers signal attenuation and interference, and thus ensures signal transmission efficiency and stability. By setting up the impedance matching circuit 7, this application enables the system to automatically achieve impedance matching, improving the user experience. The impedance matching circuit 7 may include resistive elements, capacitive elements, transformers, etc., to achieve matching relationships between the target device 6 and the wired cascaded module 3 based on parameters such as resistance matching, capacitor matching, and transformer matching.

[0076] In some embodiments, the system further includes: a user interaction module; the user interaction module is communicatively connected to the control module 1 and displays target information, a first status bit or a second status bit of the target switch 4; if the target information is in wireless transmission mode, the user interaction module can send a first instruction to the target switch 4 to switch the target switch 4 from the first status bit to the second status bit; if the target information is in wired transmission mode, the user interaction module can send a second instruction to the target switch 4 to switch the target switch 4 from the second status bit to the first status bit.

[0077] Specifically, the cascaded system of this application also includes a user interaction module, which displays target information and the first or second status bit of the target switch 4 to the user, so that the user can obtain the working status and signal transmission status of the cascaded system in real time. The user can also manually send commands to the target switch 4 to switch the status bit of the target switch 4 as needed. Specifically, if the target information is in wireless transmission mode, the user interaction module can send a first command to the target switch 4 to switch the target switch 4 from the first status bit to the second status bit. If the target information is in wired transmission mode, the user interaction module can send a second command to the target switch 4 to switch the target switch 4 from the second status bit to the first status bit, thereby improving the user experience and the flexibility and adaptability of the cascaded system.

[0078] like Figure 1 and Figure 5 As shown, in some embodiments, it further includes a power management module 8, which is communicatively connected to the wireless cascade module 2 and the target switch 4. When the target switch 4 is in a second state position, the power management module 8 regulates the power consumption of the wireless cascade module 2.

[0079] Specifically, to improve the energy efficiency and reduce power consumption of the cascaded system, the cascaded system of this application also includes a power management module 8. The power management module 8 is communicatively connected to the wireless cascaded module 2 and the target switch 4. When the target switch 4 is in its second state position and the target device 6 does not need to use the wireless cascaded module 2 for wireless signal transmission, the power management module 8 reduces the power consumption of the wireless cascaded module 2, putting it into standby or off state to save power and system processing power. Furthermore, the power management module 8 can dynamically adjust the power consumption of the wireless cascaded module 2 according to the load of the electronic device. For example, when the electronic device does not need to operate the cascaded system for signal transmission, the power consumption of the wireless cascaded module 2 is further reduced. When the wireless cascaded module 2 needs to transmit wireless signals, its power consumption can be adaptively increased to provide stable and reliable power support.

[0080] In some embodiments, the device further includes an environmental monitoring module, which is used to detect the environment in which the target device 6 is located and generate environmental parameter information that characterizes a wireless interference environment or a wireless non-interference environment. The environmental monitoring module is communicatively connected to the control module 1. If the target information is in wireless transmission mode, the environmental parameter information characterizes a wireless interference environment, and the control module 1 sends a second signal to the target switch 4.

[0081] Specifically, to improve the reliability of the cascaded system and ensure the quality and stability of signal transmission, this application also includes an environmental monitoring module in the cascaded system. This module monitors the environment in which the target device 6 is located, generating environmental parameter information that characterizes a wireless interference environment or a wireless non-interference environment. The environmental monitoring module detects influencing parameters such as noise level, signal strength, and bit error rate in the wireless frequency band to determine whether wireless interference exists in the current environment. The environmental monitoring module can set threshold values ​​for these influencing parameters. When these influencing parameters exceed the threshold values, the current environment is determined to be a wireless interference environment; when they are within the threshold values, the current environment is determined to be a wireless non-interference environment. The environmental monitoring module then generates environmental parameter information characterizing a wireless interference environment or a wireless non-interference environment. Through a communication connection with the control module 1, the control module 1 acquires the environmental parameter information. If the target information indicates a wireless transmission mode and the environmental parameter information characterizes a wireless interference environment, the control module 1 sends a second signal to the target switch 4, causing the target switch 4 to enter a second state position, enabling signal transmission to the target device 6 via wired signal transmission. This achieves dynamic adjustment of the transmission path, improves signal transmission effect, and enhances the user experience. Example

When there are multiple cascaded systems, the signal transmission needs of multiple target devices 6 can be met, the processing capability of electronic devices can be improved, and when multiple target devices 6 are connected and need to transmit signals, the multiple target switches 4 of the multiple cascaded systems can all be in the first state position to transmit wireless signals, or all be in the second state position to transmit wired signals, or some target switches 4 can be in the first state position and some target switches 4 can be in the second state position to achieve the simultaneous transmission of wireless and wired signals.
