For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0038] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

Among them, the sound pickup unit 11 is used to collect sounds in the use scenario of the sound pickup module 100, and the sounds here include at least human voices and musical instrument sounds. The encoder 12 is used to encode the collected sound to facilitate the subsequent transmission and storage of the collected sound; wherein, the encoder 12 can integrate multiple functions, such as the control of the gain, treble, midrange, bass, delay, reverberation, chorus adjustment of the sound pickup module 100, etc., so as to reduce the loss of the timbre of the picked-up instrument itself during the sound pickup process of the sound pickup module 100. The signal processor 13 is used to process the encoded digital audio, specifically using a variety of algorithms to obtain recording data. The switch component 14 is used to control the signal processing mode of the signal processor 13, so that the signal processor 13 can have different data processing methods based on different signal processing mode requirements when working.
[0049] Among them, the present application provides an optional embodiment that the signal processor 13 is configured with a musical sound processing mode and a human voice processing mode, wherein, when the signal processor 13 is in the musical sound processing mode, it can be specifically set that the signal processor 13 is in a high-quality audio processing mode. At this time, the signal processor 13 can be set to not include a human voice processing algorithm in the algorithm used when processing the audio signal, that is, the algorithm used can be for processing musical instrument sounds and / or music sounds, so that the pickup module 100 focuses on recording and processing musical instrument sounds and / or music sounds. When the signal processor 13 is in the human voice processing mode, it can be specifically set that the signal processor 13 is in the traditional audio processing mode. At this time, the signal processor 13 can be set to include a human voice processing algorithm in the algorithm used in the musical sound processing mode when processing the audio signal, so that the pickup module 100 can be used to realize the recording and processing of human voices (such as teacher teaching sounds) in the collected audio data.
[0050] Furthermore, as to whether the signal processor 13 is in the music processing mode or the vocal processing mode, the present application implements the control by means of a switch component 14 arranged in the pickup module 100. The switch component 14 is provided with a first switch state and a second switch state.

[0051] Furthermore, the pickup module 100 may further include a detection circuit 19, which may be specifically configured to be electrically connected between the switch component 14 and the signal processor 13. The detection circuit 19 may be used to detect the specific configuration state of the switch component 14, specifically to detect whether the switch component 14 is in the first switch state or the second switch state; when the detection circuit 19 detects that the switch component 14 is configured to the first switch state, it may be used to control the signal processor 13 to switch to a music processing mode; and when the detection circuit 19 detects that the switch component 14 is configured to the second switch state, it may be used to control the signal processor 13 to switch to a vocal processing mode.
[0052] The pickup module 100 provided in the present application is provided with a pickup part 11, an encoder 12, a signal processor 13, a switch component 14 electrically connected to the signal processor 13, and a detection circuit 19 provided between the switch component 14 and the signal processor 13. The switch component 14 is configured with a first switch state and a second switch state. The configuration state of the switch component 14 is detected by the detection circuit 19. When the switch component 14 is detected to be configured in the first switch state, the signal processor 13 is switched to a music processing mode. When the switch component 14 is detected to be configured in the second switch state, the signal processor 13 is switched to a human voice processing mode. Thus, the switch component 14 is used to control the pickup module 100 to have different sound processing modes under different usage requirements, so that the corresponding pickup device has a good recording effect for music (such as musical instruments) under the requirement of recording music, thereby helping to reduce or avoid the distortion problem of music recording using the pickup module 100, and helping to improve the recording effect of the pickup device for human voice and musical instrument sounds.
[0053] Please continue to refer to Figure 1 In an exemplary embodiment, the sound pickup module 100 further includes:
[0054] A power amplifier module 15 is electrically connected to the signal processor 13;
[0055] The sound playing module 16 is electrically connected to the power amplifier module 15;
[0056] The signal processor 13 in the voice processing mode transmits the audio signal to the power amplifier module 15 .
[0057] Specifically, in the pickup module 100 provided by the present application, in addition to the above-mentioned pickup unit 11, encoder 12, signal processor 13, switch assembly 14 and detection circuit 19, it can further include a power amplifier module 15 and a sound playback module 16. The input end of the power amplifier module 15 can be electrically connected to the output end of the signal processor 13 to receive the audio data processed by the signal processor 13, so as to amplify at least the relevant analog signal of the audio data according to the playback requirements, so as to ensure that the audio data can be played through the sound playback module 16 electrically connected to the output end of the power amplifier module 15. It should be supplemented that the signal processor 13 in the pickup module 100 of the present application can be set to transmit the processed audio signal to the power amplifier module 15 side only when it is in the human voice processing mode, so as to realize the human voice, or human voice and music picked up by the pickup module 100, and then played through the pickup module 100, so as to meet the user's need for recording and playing when using the pickup module 100.
[0058] The sound playing module 16 may be a device such as a speaker that can be used for sound playing.
[0059] Please continue to refer to Figure 1 In an exemplary embodiment, the sound pickup module 100 further includes:
[0060] A communication interface 17, electrically connected to the signal processor 13;
[0061] The signal processor 13 in the human voice processing mode or the musical voice processing mode transmits the audio signal to the communication interface 17 .
[0062] Specifically, in the sound pickup module 100 provided in the present application, in addition to the above-mentioned sound pickup part 11, encoder 12, signal processor 13, switch component 14 and detection circuit 19, as well as the above-mentioned power amplifier module 15 and sound playback module 16, it can further include a communication interface 17, and the communication interface 17 can be configured to be electrically connected to the output end of the signal processor 13; the signal processor 13 in the sound pickup module 100 provided in the present application can be configured to transmit the processed audio data to the remote end only through the communication interface 17 when in the music processing mode, and no longer transmit it to the power amplifier module 15 and the sound playback module 16 side, that is, the collected and processed music (such as musical instrument sound) is no longer played locally.
[0063] In addition, according to user needs, the signal processor 13 in the sound pickup module 100 provided in the present application can be set to the human voice processing mode, and the audio data processed by the signal processor 13 can be further transmitted to the remote end through the communication interface 17 to realize the local playback and remote transmission of the sound recorded by the sound pickup module 100.
[0064] The switch component 14 used in the present application has two states, which respectively control the signal processor 13 to be in a vocal processing mode or a musical sound processing mode. When the signal processor 13 is in the musical sound processing mode, it is equivalent to making the pickup module 100 be in a high-quality audio mode. At this time, when the signal processor 13 receives the music class audio signal, the (digital) signal processor 13 will exit the traditional audio algorithm module, that is, compared with the vocal processing mode, at least it will save the use of the vocal processing algorithm to process the audio data, which is beneficial to improve the processing efficiency of the signal processor 13 for music audio data and improve the ability of the signal processor 13 to process audio data.
[0065] Please continue to refer to Figure 1 In an exemplary embodiment, the encoder 12 adopts a high frequency sampling encoder 12, and the sampling frequency of the high frequency sampling encoder 12 is F, where F=48kHz.
[0066] Specifically, the present application also provides an optional implementation method in which the encoder 12 in the sound pickup module 100 adopts a high-frequency sampling encoder 12, and the sampling frequency of the high-frequency sampling encoder 12 can be set to 48kHz, so that the sound pickup module 100 can achieve sampling of the second harmonic of the musical instrument, so as to improve the sound pickup module 100 for the sound pickup effect of the musical instrument audio, and avoid the situation where the collected audio data loses the original timbre of the musical instrument.
[0067] Figure 2 A schematic diagram of the structure of the sound pickup module in another embodiment of the present application is shown. Figure 2 In an exemplary embodiment, the sound pickup module 100 may be further configured with an external device access port 20, the output end of which is electrically connected to the signal processor 13 and the encoder 12 respectively; wherein the external device access port 20 at least includes a music data access port 21 and a human voice data access port 22;
[0068] The music data access port 21 is used to access music data, and the vocal data access port 22 is at least used to access vocal data.
[0069] Specifically, the sound pickup module 100 provided in the present application, when the signal processor 13 is in the human voice processing mode, the algorithm adopted by the signal processor 13 in processing the audio data includes at least the human voice processing algorithm, and the audio data processed by the signal processor 13 can be set as required to be played locally only through the power amplifier module 15 and the sound playback module 16, and can also be set to be further transmitted to a remote end through the communication interface 17; when the signal processor 13 is in the music sound processing mode, the signal processor 13 at least reduces the use of the human voice processing algorithm in the processing of the audio data compared to the human voice processing mode, and the audio data processed by the signal processor 13 can be set as required to be transmitted to a remote end only through the communication interface 17 without being played locally.
[0070] Based on this, the present application also provides an optional implementation method, in which an external device access port 20 can be further configured in the sound pickup module 100, and the output end of the external device access port 20 can be set to be electrically connected to the input end of the signal processor 13, and at the same time electrically connected to the input end of the encoder 12; wherein, the external device access port 20 can be set to include at least one music data access port 21 and a human voice data access port 22, and the user can use the signal processor 13 of the sound pickup module 100 according to the needs, and use an algorithm that at least includes a human voice processing algorithm to perform data processing, so as to correspondingly transmit the external audio data to the sound pickup module 100 through the human voice data access port 22; or to use an algorithm that does not include a human voice processing algorithm for processing, then the external audio data is correspondingly transmitted to the sound pickup module 100 through the music data access port 21.
[0071] Furthermore, when the sound pickup module 100 provided in the present application is configured with an external device access port 20 including a music data access port 21 and a human voice data access port 22, the external device access port 20 can intelligently identify whether the user is using the music data access port 21 or the human voice data access port 22 to transmit audio data to the sound pickup module 100, and then send different level signals to the signal processor 13 according to the recognition result, so that the signal processor 13 can adjust itself to the music processing mode according to the recognition that audio data is transmitted through the music data access port 21, and the signal processor 13 can adjust itself to the human voice processing mode according to the recognition that audio data is transmitted through the human voice data access port 22. It should be added that, only when the switch component 14 is in a suspended state (not the first switch state and the second switch state mentioned above) will the signal processor 13 automatically change its data processing state according to whether the audio data is transmitted to it through the music data access port 21 or the human voice data access port 22. If the switch component 14 has already selected the data processing state of the signal processor 13, the state selected by the switch component 14 is still the main state; that is, the control priority of the switch component 14 in the pickup module 100 for the data processing state (mode) of the signal processor 13 is higher than the control priority of the peripheral access port 20 for the data processing state of the signal processor 13.
[0072] like Figure 2 As shown, the external device access port 20 can be integrated into the sound pickup portion 11 , or the external device access port 20 can be separately provided relative to the sound pickup portion 11 .

[0079] It should be noted that Figure 3 and Figure 4 This is only a schematic diagram of a circuit structure of the connector 14 provided in this application, and this application is not limited thereto.
[0080] Figure 5 A partial circuit structure diagram of a pickup module in an embodiment of the present application is shown. Figure 2 and Figure 5 , the sound pickup module 100 also includes:
[0081] The detection circuit 19 includes a signal input terminal Vdd and a signal output terminal, and the signal output terminal is electrically connected between the switch component 14 and the signal processor 13; the detection circuit 19 outputs a first signal or a second signal to the signal processor 13 according to the detected switching state of the switch component 14; the signal processor 13 switches to a music processing mode according to the first signal, and switches to a human voice processing mode according to the second signal; wherein the first signal and the second signal are different.
[0082] Specifically, the present application also provides a circuit configuration method that can be selected for the detection circuit 19, such as Figure 5As shown, the detection circuit 19 can be specifically configured to include a signal input terminal Vdd, and the signal input terminal Vdd is electrically connected between the switch component 14 and the signal processor 13 through a resistor, that is, the signal output terminal of the detection circuit 19 is electrically connected between the switch component 14 and the signal processor 13; when the switch component 14 is in an on state, the voltage signal of the signal input terminal Vdd of the detection circuit 19 is transmitted to the input terminal of the signal processor 13, and when the switch component 14 is in a off state, the voltage signal of the signal input terminal Vdd of the detection circuit 19 is not transmitted to the input terminal of the signal processor 13, thereby, by the switch component 14 being in different states, different electrical signals are controlled to be transmitted to the signal processor 13 in different states.
[0083] Specifically, for example, the detection circuit 19 is used to switch the signal processor 13 to the music processing mode when it detects that the switch component 1414 is configured to the first switch state, and to switch the signal processor 13 to the vocal processing mode when it detects that the switch component 1414 is configured to the second switch state; the first switch state and the second switch state obtained here can correspond to the above-mentioned on state and off state.
[0084] Furthermore, the detection circuit 19 can be further configured to detect the level of the electrical signal transmitted when the switch component 14 is in different states. For example, after the detection circuit 19 transmits a first signal based on the detected switch state of the switch component 14 being in the first switch state, the signal processor 13 is driven to switch to the music processing mode; for example, after the detection circuit 19 transmits a second signal based on the detected switch state of the switch component 14 being in the second switch state, the signal processor 13 is driven to switch to the vocal processing mode. This is conducive to accurately identifying the switch state of the switch component 14 and driving the signal processor 13 to change to the required data processing state.
[0085] Please continue to refer to Figure 2 In an exemplary embodiment, the sound pickup portion 11 is configured with a sound pickup range, and the sound pickup range is the range of the musical instrument to be picked up by the sound pickup module 100.
[0086] Specifically, the present application also provides an optional implementation method, in which the pickup range of the pickup part 11 of the pickup module 100 can be set to be greater than or equal to the range of the musical instrument to be picked up by the pickup module 100, so as to ensure the integrity of the sound of the musical instrument picked up by the pickup module 100, avoid the situation where the timbre of the musical instrument picked up by the pickup module 100 is missing, thereby helping to improve the pickup effect of the pickup module 100.
[0087] Please continue to refer to Figure 2In an exemplary embodiment, the switch assembly 14 is a dip switch or a touch switch; wherein the first switch state and the second switch state include an on state and a off state.
[0088] Specifically, the present application also provides an optional implementation method in which the switch component 14 can be set as a physical switch. The present application does not limit the specific control method of the switch. For example, the switch component 14 can be set as a dip switch or a touch switch. The dip switch can be any one of a push switch, a sliding switch, and a knob switch to facilitate user operation, mainly to adapt to the product.
[0089] Please continue to refer to Figure 2 In an exemplary embodiment, the sound pickup module 100 further includes:
[0090] The power module 18 is at least electrically connected to the signal processor 13 .
[0091] Specifically, the pickup module 100 also needs to be configured with a power module 18 for providing electrical energy thereto. The power module 18 can be optionally set to be electrically connected to at least the signal processor 13 so that the signal processor 13 can improve its ability and efficiency in processing data with the support of electrical energy.
[0092] Figure 6 A schematic diagram of a sound pickup device in an embodiment of the present application is shown. Figure 1 Reference Figure 6 Based on the same concept, the present application also provides a sound pickup device 200, the sound pickup device 200 includes any of the above-mentioned sound pickup modules 100, and the sound pickup device 200 includes a housing;
[0093] At least the sound pickup portion 11 and the switch assembly 14 in the sound pickup module 100 are disposed on the outer surface of the housing.
[0094] Specifically, the sound pickup device 200 including the sound pickup module 100 can be configured to include a shell, wherein the sound pickup part 11 and the switch assembly 14 in the sound pickup module 100 can be optionally arranged on the outer surface of the shell, so as to facilitate the clarity of sound pickup by the sound pickup part 11 and facilitate the user's control operation of the switch assembly 14; the encoder 12 and the signal processor 13 can be optionally arranged inside the shell to ensure the aesthetics and durability of the sound pickup device 200. The arrangement of the remaining structural parts in the sound pickup device 200 is not specifically limited in this application, and their arrangement positions can be adjusted according to needs.
[0095] The sound pickup device 200 provided in the present application can be used in educational vocal recording and music teaching scenarios at a low cost. It adopts a switch mode (switch component 14) to set a high-quality audio channel, that is, the signal processor 13 is in the music processing mode. When the processor receives the music class signal, the digital processor exits the traditional audio algorithm module; the encoder 12 is set to a high-frequency sampling mode, that is, a high-frequency sampling encoder 12 is used. The audio data of the music class, which focuses on the sound of musical instruments, can be directly output to the remote end after being processed in the digital processor; for this part of the audio, the local audio is no longer played. When the digital processor is in the vocal processing mode, that is, in the ordinary vocal teaching scenario, the conventional algorithm including the vocal processing algorithm is still used to process the audio data, and the audio is played through the sound pickup device 200.
[0096] It should be noted that the sounds of musical instruments are not played locally, because in an educational scenario, the teacher's voice needs to be amplified locally, while the sounds of musical instruments generally do not require local amplification.
