The audio processing application 111 is used to process and calculate the received signal, and optionally return the processed audio signal and/or control signal to the audio transmission device 120 . For example, the above-mentioned noise reduction application program has a noise reduction function for filtering out noise of a speech signal and generating a clean speech signal. The above-mentioned voiceprint recognition application program has the function of judging the specific identity of the speaker. In a possible embodiment, the voiceprint recognition application converts a speech signal into a sound pattern, and determines the speaker's identity. The above-mentioned sound source direction recognition application program has the function of judging the direction of the speaker, and is used to judge the sound source direction of a speech signal according to the received speech signal, and can selectively return at least one control signal to the sound source transmission device 120, so as to Control at least one mechanism component to rotate/move toward the direction of the sound source. In this example, the mechanical component acts according to the control signal.

The native applications 112 and 113 only act according to the voice signal provided by the media manager 114 . The present invention does not limit the types of the native applications 112 and 113 . In a possible embodiment, the native application program 112 is a map application program (such as google map), which presents a corresponding map according to a voice signal provided by the media manager 114 .

The media manager 114 is used to provide voice signals to the native applications 112 and 113 . In a possible embodiment, the media manager 114 is a native media manager. If the electronic device 110 is operated in the Android system, the media manager 114 is an Android native media manager. In other embodiments, the media manager 114 receives external audio signals through a driver (not shown). In this example, the driver is an Android driver.

The transmission interface 115 is used for coupling the audio transmission device 120 . The present invention does not limit the type of the transmission interface 115 . In a possible embodiment, the transmission interface 115 includes a USB connector. In this example, the USB connector might be a Type-C connector. In another embodiment, if the electronic device 110 operates on an iOS system, the transmission interface 115 is a Lightning connector. In other embodiments, the transmission interface 115 is a wireless transceiver, which receives external signals (data and/or power) or outputs signals (data and/or power) wirelessly.

The sound source transmission device 120 is used to detect an external sound source AS, and provide a voice signal to the electronic device 110 . In this embodiment, the sound source transmission device 120 first packages the external sound source AS into a voice signal (or called the first voice signal) in the format of a vendor-defined class (Vendor defined class), and then provides the first voice signal through the transmission interface 115 Give the electronic device 110. The audio processing application program 111 of the electronic device 110 processes and calculates the received first audio signal, and optionally returns the processed first audio signal and/or control signal to the audio transmission device 120 . For example, the audio processing application program 111 of the electronic device 110 can be a noise reduction application program, which processes the first voice signal to filter out the noise component of the first voice signal, and returns a clean voice signal to the audio source Transmission device 120 .

In a possible embodiment, the first audio signal has four channels of audio information. In this example, the noise reduction application program (such as the audio processing application program 111) finds out the source channel with the main speech component from the first speech signal, and filters out the speech components of other channels other than the source channel (ie, the noise component ). The noise reduction application program provides the speech components of the source channel to the audio transmission device 120 .

After receiving the noise-reduced speech component, the audio source transmission device 120 sends the noise-reduced speech signal (that is, the noise-reduction application program) through a specific device (a device recognized by the media manager 114, such as an audio circuit). returned voice) to the media manager 114. The media manager 114 then provides the clean audio signal to the native applications 112 and/or 113 . Therefore, the actions of the native applications 112 and/or 113 will not be affected by environmental noise.

In this embodiment, the noise reduction processing is performed outside the sound source transmission device 120 , that is, in the electronic device 110 . Therefore, there is no need to additionally arrange a digital signal processor in the audio transmission device 120 , thereby reducing the component cost of the audio transmission device 120 . In addition, even if the sound source transmission device 120 does not have a digital signal processor, it can still provide the electronic device 110 with a voice signal without environmental noise. Therefore, the electronic device 110 can correctly determine the meaning represented by the voice signal.

The present invention does not limit the type of the sound source transmission device 120 . In this embodiment, the sound source transmission device 120 is a Dongle. In other embodiments, the audio transmission device 120 may be integrated into a charging cable (not shown). Therefore, the electronic device 110 can receive the voice signal while being charged. In addition, the audio transmission device 120 may have an audio output terminal (not shown). In this example, when the user plugs the earphone into the audio output port of the audio transmission device 120 , the user can receive the voice (such as music) output by the electronic device 110 through the audio transmission device 120 . Still in other embodiments, the sound source transmission device 120 may integrate at least one mechanical component, such as at least one of a rotating shaft and a roller. In this example, the rotating shaft/roller of the sound source transmission device 120 can rotate/move according to at least one control signal received.

FIG. 2 is a possible embodiment of the audio transmission device 120 of the present invention. In this embodiment, the audio source transmission device 120 includes a transmission interface 210 , a vendor defined class circuit 220 , an audio class circuit 230 and a sensing circuit 240 .

The sensing circuit 240 detects the external audio source AS for generating an input voice AD _IN . The invention does not limit the architecture of the sensing circuit 240 . The sensing circuit 240 has at least one sound sensor. In a possible embodiment, the sensing circuit 240 is a microphone array. In this example, the microphone array may consist of four microphones to detect sounds from four directions. In this example, the input voice AD _IN has four channels of voice. In other embodiments, the microphone array may have more or fewer microphones.

The vendor-defined category circuit 220 generates a voice signal AD _S1 according to the input voice AD _IN . In a possible embodiment, the vendor defined class circuit 220 packs the voice signal AD _S1 into a signal of a vendor defined class format. In another possible embodiment, the vendor-defined class circuit 220 converts the input voice AD _IN into a USB format, and then provides the converted result (that is, the voice signal AD _S1 ) to an external electronic device (such as 110) through the transmission interface 210 . The audio processing application program (such as 111 ) in the external electronic device processes and calculates the received voice signal AD _S1 to generate a processed voice AD _CN , and sends it back to the manufacturer-defined category circuit 220 through the transmission interface 210 . For example, the audio processing application 111 of the electronic device 110 can be a noise reduction application, which filters out the noise component of the voice signal AD _S1 to generate a processed voice AD _CN , and sends it back to the manufacturer through the transmission interface 210 Custom class circuit 220 . In a possible embodiment, the vendor-defined category circuit 220 stores and processes the voice AD _CN . At this time, the processed speech AD _CN is a clean speech signal without noise components.

The audio category circuit 230 receives and processes the voice AD _CN through the vendor-defined category circuit 220, and provides the processed voice AD _CN as a voice signal AD _S2 to the media manager (such as 114) of the external electronic device. Since the voice signal AD _S2 is a clean voice signal without noise components, when the media manager 114 provides the voice signal AD _S2 to the native application 112 or 113, the native application 112 or 113 can correctly recognize the voice signal AD _S2 , and respond correctly.

For example, assume that the native application program 112 presents corresponding text according to the voice signal AD _S2 . In this example, if the voice signal AD _S2 contains noise components, the native application program 112 may display wrong text. However, since the audio class circuit 230 provides a clean speech signal to the media manager 114, the native application 112 can render correct text. The present invention does not limit the architecture of the audio category circuit 230 . In a possible embodiment, the audio class circuit 230 is a USB audio class (USB audio class; UAC) circuit.

The transmission interface 210 is used for outputting voice signals AD _S1 and AD _S2 , and receiving and processing voice AD _CN . The present invention does not limit the type of the transmission interface 210 . In this embodiment, the type of the transmission interface 210 is the same as that of the transmission interface 115 . For example, if the transmission interface 115 is a wireless transceiver, the transmission interface 210 is also a wireless transceiver. In other embodiments, if the transmission interface 115 is a USB connector, the transmission interface 210 is also a USB connector. In a possible embodiment, the transmission interface 210 transmits the voice signals AD _S1 , AD _S2 and processes the voice AD _CN through the D+ and D− pins of the USB connector.

Since the manufacturer's self-defined category circuit 220 and the audio category circuit 230 are simultaneously built in the sound source transmission device 120, when the sound source transmission device 120 is connected to a computer or a monitoring system, in the file manager of the computer and in the monitoring system, it can be It is observed that the sound source transmission device 120 has both a manufacturer-defined category and an audio category. The conventional audio source transmission device (with digital signal processor) only builds an audio class circuit, which is responsible for playing and receiving audio, and does not involve audio processing. Therefore, when connected to a computer or a monitoring system, in the file manager of the computer and the monitoring system, only the sound source transmission device can be observed to have the audio category. However, the audio transmission device 120 of the present disclosure utilizes the manufacturer-defined class circuit 230 to package the audio signal AD _S1 into a signal of a manufacturer-defined type format, and provides the signal to an external electronic device (such as 110 ) through the transmission interface 210 for audio processing. Therefore, an additional digital signal processor or audio processing circuit does not need to be provided in the sound source transmission device 120 , thus greatly reducing the component cost of the sound source transmission device 120 .

Fig. 3 is another possible embodiment of the audio transmission device of the present invention. As shown in the figure, the audio transmission device 120 includes a transmission interface 310 , a manufacturer-defined category circuit 320 , an audio category circuit 330 , a sensing circuit 340 and an analog-to-digital converter (ADC) 350 . Since the characteristics of the transmission interface 310, the manufacturer-defined class circuit 320, the audio class circuit 330, and the sensing circuit 340 are the same as those of the transmission interface 210, the vendor-defined class circuit 220, the audio class circuit 230, and the sensing circuit 240 in FIG. 2 Similar, so no more details.

In this embodiment, the analog-to-digital converter 350 converts the input voice AD _IN to generate a digital signal AD _IND for the vendor-defined category circuit 320 . The vendor-defined class circuit 320 processes the digital signal AD _IND to generate the voice signal AD _S1 . In a possible embodiment, the analog-to-digital converter 350 is integrated in the sensing circuit 340 or the manufacturer-defined class circuit 320 .

Fig. 4 is another possible embodiment of the audio transmission device of the present invention. As shown in the figure, the audio source transmission device 120 includes a transmission interface 410 , a manufacturer-defined category circuit 420 , an audio category circuit 430 , a sensing circuit 440 and a hub (Hub) 450 . Since the characteristics of the transmission interface 410, the vendor-defined class circuit 420, the audio class circuit 430, and the sensing circuit 440 are the same as those of the transmission interface 210, the vendor-defined class circuit 220, the audio class circuit 230, and the sensing circuit 240 in FIG. 2 similar, so no more details.

In this embodiment, the hub 450 includes an uplink port 451 and downlink ports 452 and 453 . In a possible embodiment, the hub 450 is a USB hub. The uplink port 451 is used to provide voice signals AD _S1 and AD _S2 to the transmission interface 410 and receive and process the voice AD _CN . The downlink port 452 is coupled to the vendor-defined category circuit 420 for providing the audio signal AD _S1 to the uplink port 451 and receiving the processed audio AD _CN from the uplink port 451 . The downlink port 453 is coupled to the audio class circuit 430 for providing the voice signal AD _S2 to the uplink port 451 .

In other embodiments, the audio transmission device 120 further includes a micro control circuit 460 . The micro control circuit 460 generates a control signal SC ₁ for instructing the vendor-defined category circuit 420 to output the voice signal AD _S1 to the downlink port 452 . In this example, the vendor-defined category circuit 420 also receives the processed voice AD _CN from the downstream port 452 according to the control signal SC ₁ . In another possible embodiment, the micro control circuit 460 further generates a control signal SC ₂ for instructing the audio class circuit 430 to output the voice signal AD _S2 to the downlink port 453 . In this example, the audio category circuit 430 also receives the processed audio AD _CN from the vendor-defined category circuit 420 according to the control signal SC ₂ .

In other embodiments, the micro control circuit 460 further controls the sensing circuit 440 . In this example, the micro control circuit 460 commands the sensing circuit 440 to provide the input voice AD _IN through a control signal SC ₃ . The microcontroller circuit 460 determines whether the input voice AD _IN is greater than a preset value. When the input voice AD _IN is greater than the preset value, it means that the external audio source AS is an effective audio source. Therefore, the micro-control circuit 460 commands the sensing circuit 440 to provide the input voice AD _IN to the manufacturer-defined category circuit 420 through the control signal SC ₃ . However, when the input voice AD _IN is not greater than the preset value, it means that the external sound source AS is an invalid sound source (such as noise). Therefore, the micro-control circuit 460 commands the sensing circuit 440 not to provide the input voice AD _IN to the manufacturer-defined category circuit 420 through the control signal SC ₃ . In other embodiments, at least one of the vendor-defined class circuit 420 , the audio class circuit 430 and the microcontroller circuit 460 may be located in the hub 450 . In one embodiment, the vendor-defined class circuit 420 , the audio class circuit 430 and the microcontroller circuit 460 are all located in the hub 450 .

FIG. 5 is similar to FIG. 2 , the difference is that there is an additional transmission interface 550 in FIG. 5 . Because the characteristics of the transmission interface 510, the vendor-defined class circuit 520, the audio class circuit 530, and the sensing circuit 540 in FIG. The characteristics of the circuit 240 are similar, so they will not be repeated here.

The transmission interface 550 is used for sending an output voice AD _OUT . In a possible embodiment, the audio category circuit 530 receives the output voice AD _OUT from the external electronic device (such as 110 ) through the transmission interface 510 and provides it to the transmission interface 550 . In another possible embodiment, the transmission interface 550 is to transmit the processed voice AD _CN .
