When the peripheral device connected to the signal transmitting module 20 is a USB accessory, the signal transmission port P1 can also be used to detect the type of the USB accessory. The signal transmission ports P3 and P4 also have their respective functions when the signal transmission module 20 is connected to an audio device and a USB accessory. The signal transmission port P4 can be connected to the audio device detection circuit D2 to detect whether the device externally connected to the signal transmission module 20 is an audio device, and the audio device detection circuit D2 further includes a multi-button detection circuit D3, which can be used for detecting audio. The type of device to determine if the audio device is a multi-button audio device. In other embodiments, the multi-button detection circuit D3 may be separately present in the signal transmission module 20, and is not limited thereto. When the system determines that the peripheral circuit externally connected to the signal transmission module 20 is an audio device, in addition to the signal transmission ports P1 and P2 can be used to transmit the audio signal, the signal transmission port P3 can also be connected to the external microphone through the switching of the switching circuit S4.

When the system determines that the peripheral circuit externally connected to the signal transmission module 20 is a USB accessory, the signal transmission ports P3 and P4 can be used to transmit USB data. The signal transmission ports 5P5 and P6 are respectively connected to the power terminal and the ground terminal. When the peripheral device connected to the signal transmission module 20 has no power supply, the signal transmission 埠P5 can be used to supply power to the peripheral device. When the peripheral device connected to the signal transmission module 20 has a power supply, the signal transmission port P5 can also receive the power supply from the peripheral device.

請參考第3圖，第3圖為本創作實施例訊號傳輸模組20外接於具有電源供應且具有多按鍵功能之音訊裝置30之示意圖。如第3圖所示，具有電源供應且具有多按鍵功能之音訊裝置30可能為一種較大型的喇叭或音響，這種喇叭或音響往往包含有多個控制按鍵，以提供使用者進行相關於聲音播放的操作，例如調整音量、切換歌曲、切換頻道、切換播放模式等。音訊裝置30包含一聲音播放裝置302、一麥克風裝置304及數個偵測用電阻。聲音播放裝置302之正輸出端及負輸出端分別連接於訊號傳輸埠P1及P2，麥克風裝置304連接於訊號傳輸埠P3，而偵測用之電阻則連接於訊號傳輸埠P4。由於音訊裝置30已具有電源供應，不需要再由訊號傳輸模組20接收電源，因此訊號傳輸埠P5不需連接至音訊裝置30之內部電路，而形成斷路或空接的情況。詳細來說，音訊裝置偵測電路D2透過訊號傳輸埠P4偵測到音訊裝置30中的電阻，以判斷此外接裝置為音訊裝置。多按鍵偵測電路D3再根據這些電阻之阻值，判斷音訊裝置30為具有多按鍵功能之音訊裝置。接著，訊號傳輸模組20會透過訊號傳輸埠P5送出一電源，並再次經由訊號傳輸埠P4偵測電阻之阻值，由於訊號傳輸埠P5為斷路或空接，因此電阻值不會改變，可據以判斷音訊裝置30本身已帶有電源。根據以上偵測結果，系統可判斷音訊裝置30為具有電源供應且具有多按鍵功能之音訊裝置，進而關閉訊號傳輸埠P5輸出的電源，系統另關閉切換電路S2並開啟切換電路S3，以使用功率較大的揚聲放大器204來傳送聲音訊號，並將切換電路S4切換至傳送麥克風訊號的模式，以經由訊號傳輸埠P3進行麥克風訊號的接收及處理。Please refer to FIG. 3 . FIG. 3 is a schematic diagram of the audio transmission module 20 externally connected to the audio device 30 having a power supply and having multiple buttons. As shown in FIG. 3, the audio device 30 having a power supply and having a multi-button function may be a larger speaker or stereo, and the speaker or sound often includes a plurality of control buttons to provide a user with a related sound. Playback operations, such as adjusting the volume, switching songs, switching channels, switching playback modes, and more. The audio device 30 includes a sound playback device 302, a microphone device 304, and a plurality of detection resistors. The positive output terminal and the negative output terminal of the sound playback device 302 are respectively connected to the signal transmission ports P1 and P2, the microphone device 304 is connected to the signal transmission port P3, and the detecting resistor is connected to the signal transmission port P4. Since the audio device 30 already has a power supply, there is no need to receive power from the signal transmission module 20, so the signal transmission port P5 does not need to be connected to the internal circuit of the audio device 30 to form an open or empty connection. In detail, the audio device detecting circuit D2 detects the resistance in the audio device 30 through the signal transmission port P4 to determine that the external device is an audio device. The multi-button detection circuit D3 determines that the audio device 30 is an audio device having a multi-button function based on the resistance values of the resistors. Then, the signal transmission module 20 sends a power source through the signal transmission port P5, and detects the resistance value of the resistor through the signal transmission port 4P4 again. Since the signal transmission port P5 is open or empty, the resistance value does not change. It is judged that the audio device 30 itself has a power source. According to the above detection result, the system can determine that the audio device 30 is an audio device having a power supply and having a multi-button function, thereby turning off the power output of the signal transmission port P5, and the system further turns off the switching circuit S2 and turns on the switching circuit S3 to use the power. The larger speaker amplifier 204 transmits the sound signal, and switches the switching circuit S4 to the mode for transmitting the microphone signal to receive and process the microphone signal via the signal transmission port P3.

請參考第4圖，第4圖為本創作實施例訊號傳輸模組20外接於不具有電源供應但具有多按鍵功能之音訊裝置40之示意圖。如第4圖所示，不具有電源供應但具有多按鍵功能之音訊裝置40可能為中型或小型的喇叭或音響，這種喇叭或音響亦包含有多個控制按鍵，以提供使用者進行相關於聲音播放的操作。音訊裝置40同樣包含一聲音播放裝置402、一麥克風裝置404及數個偵測用電阻。聲音播放裝置402之正輸出端及負輸出端分別連接於訊號傳輸埠P1及P2，麥克風裝置404連接於訊號傳輸埠P3，而偵測用之電阻則連接於訊號傳輸埠P4。音訊裝置40與音訊裝置30的主要差別在於，音訊裝置40不具有電源供應，必須由訊號傳輸模組20供應電源。因此，訊號傳輸埠P5另連接至音訊裝置40之內部電路以提供電源，並連接於上述電阻以進行相關於電源供應之偵測。在此實施例中，訊號傳輸埠P5係透過一電晶體連接至電阻。詳細來說，音訊裝置偵測電路D2透過訊號傳輸埠P4偵測到音訊裝置40中的電阻，以判斷此外接裝置為音訊裝置。多按鍵偵測電路D3再根據音訊裝置40中的電阻值判斷音訊裝置40為具有多按鍵功能之音訊裝置。接著，訊號傳輸模組20會透過訊號傳輸埠P5送出一電源，並再次經由訊號傳輸埠P4偵測電阻之阻值，由於來自於訊號傳輸埠P5之電源影響了電阻的等效阻值，使得音訊裝置偵測電路D2經由訊號傳輸埠P4偵測到的阻值改變，可據以判斷音訊裝置40本身不帶有電源，必須由訊號傳輸模組20供應電源。根據以上偵測結果，系統可判斷音訊裝置40為不具有電源供應但具有多按鍵功能之音訊裝置，進而持續開啟訊號傳輸埠P5，以輸出電源提供予音訊裝置40使用，系統另關閉切換電路S2並開啟切換電路S3，以使用功率較大的揚聲放大器204來傳送聲音訊號，並將切換電路S4切換至傳送麥克風訊號的模式，以經由訊號傳輸埠P3進行麥克風訊號的接收及處理。Please refer to FIG. 4 . FIG. 4 is a schematic diagram of the audio transmission module 20 externally connected to the audio device 40 having no power supply but having a multi-button function.

The speaker or stereo also includes a plurality of control buttons to provide a user with relevant sound The operation of the sound playback. The audio device 40 also includes a sound playback device 402, a microphone device 404, and a plurality of detection resistors. The positive output terminal and the negative output terminal of the sound playback device 402 are respectively connected to the signal transmission ports P1 and P2, the microphone device 404 is connected to the signal transmission port P3, and the detecting resistor is connected to the signal transmission port P4. The main difference between the audio device 40 and the audio device 30 is that the audio device 40 does not have a power supply and must be powered by the signal transmission module 20. Therefore, the signal transmission port P5 is further connected to the internal circuit of the audio device 40 to provide power and is connected to the above resistor for detection related to the power supply. In this embodiment, the signal transmission port P5 is connected to the resistor through a transistor. In detail, the audio device detecting circuit D2 detects the resistance in the audio device 40 through the signal transmission port P4 to determine that the external device is an audio device. The multi-button detection circuit D3 determines the audio device 40 as an audio device having a multi-button function according to the resistance value in the audio device 40. Then, the signal transmission module 20 sends a power source through the signal transmission port P5, and detects the resistance value of the resistor again through the signal transmission port 4P4, because the power source from the signal transmission port P5 affects the equivalent resistance of the resistor, so that The change of the resistance value detected by the audio device detection circuit D2 via the signal transmission port 4P4 can be determined according to the fact that the audio device 40 itself does not have power supply, and the signal transmission module 20 must be supplied with power. According to the above detection result, the system can determine that the audio device 40 is an audio device that does not have a power supply but has a multi-button function, and then continuously turns on the signal transmission port P5, and the output power is supplied to the audio device 40, and the system further turns off the switching circuit S2. The switching circuit S3 is turned on to transmit the audio signal by using the high-powered speaker amplifier 204, and the switching circuit S4 is switched to the mode for transmitting the microphone signal to receive and process the microphone signal via the signal transmission port P3.

As shown in FIG. 5, the earphone device 50 can be connected to the signal transmission module 20 through an adapter 502. The adapter 502 also includes a detection resistor connected to the signal transmission port P4 for detection. The audio device detecting circuit D2 detects the resistance in the adapter 502 through the signal transmission port P4 to determine that the external device is the earphone device 50. According to the above detection result, the system can turn off the switching circuit S3 and turn on the switching circuit S2 to transmit the headphone amplifier 202 with less power.
