[0025] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0026] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0027] It should also be noted that the directional terms such as left, right, up and down in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0028] Please refer to Figure 1, which shows a schematic diagram of the connection of some functional modules of the electronic device in an embodiment of the present application. The electronic device 100 provided in the present application includes a control unit 12, a first audio signal processing unit 111, a second audio signal processing unit 112, and an audio playback unit 113; the first audio signal processing unit 111 is electrically connected to the second audio signal processing unit 112; the first audio signal processing unit 111 receives an audio signal input, and then decodes the received audio signal and sends it to the second audio signal processing unit 112. The control unit 12 is electrically connected to the second audio signal processing unit 112, and is used to control the second audio signal processing unit 112 to process the human voice signal or background sound signal in the audio signal; the audio playback unit 113 is electrically connected to the second audio signal processing unit 112, and is used to play the audio signal processed by the first audio signal processing unit 111 and the second audio signal processing unit 112, so as to realize the output of the audio signal as sound.

[0029] In the present application, the second audio signal processing unit 112 integrated in the electronic device can process the human voice signal or background sound signal in the audio signal. For example, removing the human voice signal can help the user remove the human voice of the original song and retain only the accompaniment, which is convenient for the user to sing along or sing in chorus; removing the background sound signal can help the user remove the background music in the song and retain only the human voice, which is convenient for the user to record or analyze the human voice singing. Of course, the second audio signal processing unit 112 integrated in the electronic device in the present application can also perform other processing on the human voice signal or background sound signal in the audio signal, such as reducing or increasing the magnitude of the current or voltage of the human voice signal or background sound signal, thereby adjusting the magnitude of the human voice or background sound. If the user is not confident in his or her singing skills when singing karaoke, he or she can retain the human voice signal, such as swapping the human voice signal, so that he or she can sing along and avoid the original singer's voice in the song covering up the user's voice, thereby improving the user's experience of using the electronic device.

[0030] refer to Figure 2, which shows a schematic diagram of an implementation method of using or not using the second audio signal processing unit 112 to process the audio signal in an embodiment. The control unit 12 is a switch connected in parallel to both ends of the second audio signal processing unit 112. When the switch is closed, the source audio signal is processed by the first audio signal processing unit 111 and then directly input into the audio playback unit 113 for audio output. At this time, the electronic device does not perform any processing on the human voice signal or background signal in the audio signal, and the electronic device is in audio appreciation mode. When the switch is disconnected, the source audio signal is processed by the first audio signal processing unit 111 and then input into the second audio signal processing unit 112 for processing the human voice signal or background sound signal and then sent to the audio playback unit 113 for audio output. The control unit is a switch that can simply and quickly select whether to process the human voice signal or background signal. The product implementation cost is low and can improve the user experience of the product.

[0031] By using the electronic device in this application, users do not need to connect another mobile terminal such as a mobile phone or tablet with karaoke software to the electronic device before they can sing karaoke. The audio data source is also not limited to the audio data source in the karaoke software (such as Kugou, QQ Music). Users can use this electronic device to connect to the audio data source in devices such as the Internet, CDs, and TVs to directly sing karaoke, which greatly improves the product user experience.

[0032] It should be noted that in the present application, the second audio signal processing unit 112 can be implemented by either analog or digital methods. The analog method mainly includes using a band-stop filter or an equalizer, while the digital method mainly includes DSP (digital signal processing) technology.

[0033] In the present application, the control unit can be a physical button, knob or other structure provided on the electronic device, or a touch button provided on the electronic device, or a device independent of the electronic device and connected to the electronic device by wire or wirelessly. For example, the control unit can be integrated into the APP software used in conjunction with the electronic device or the remote control device used in conjunction with the electronic device.

[0034] Specifically, please refer to Figure 3As shown, in one embodiment, the control unit is a button 12 provided on the housing of the electronic device 100. By triggering the button 12, the second audio signal processing unit 112 can be controlled to eliminate or not eliminate the human voice signal or background sound signal in the audio signal, thereby turning the human voice signal or background sound signal on or off in the output audio signal. For example, when the button 12 is in the pop-up state, the second audio signal processing unit 112 is not connected to the audio signal processing circuit and does not process the audio signal. The electronic device outputs the audio signal processed by the first audio signal processing unit 112 and is in audio appreciation mode. When the button 12 is pressed, the second audio signal processing unit 112 is connected to the audio signal processing circuit and processes the human voice signal or background sound signal in the audio signal. The electronic device is in sing-along mode or original sound analysis mode.

[0035] In another embodiment, Figure 4 As shown, the control unit is a knob 12 located on the housing of the electronic device 100. Rotating this knob 12 adjusts the volume of the human voice or background sound signal within the audio signal. It should be noted that in this embodiment, the knob 12 does not adjust the overall volume of the electronic device's output audio. Instead, it adjusts only the volume of the human voice or background sound signal within the audio signal, thereby adjusting only the volume of the human voice or background sound signal. For example, the knob 12 is configured to adjust the volume of the human voice within the audio. When the user activates the knob 12, the second audio signal processing unit 112 performs analog or digital processing on the human voice within the audio signal to adjust the volume of the human voice. When the user uses the electronic device for karaoke, they can activate the knob 12 to reduce the volume of the human voice, allowing them to sing along or sing along. When the user uses the electronic device to enjoy audio, they can simply increase the volume of the human voice to a normal level. It should be noted that in this embodiment, the minimum value for the human voice volume adjustment is 0, indicating no-voice mode; the maximum value is a normal level, indicating audio enjoyment mode.

[0036] Furthermore, in another embodiment, a rotatable button can be set on the housing of the electronic device 100 as a control unit. Pressing the rotatable button can turn on or off the human voice signal or background sound signal in the audio signal, and rotating the rotatable button can adjust the size of the human voice signal or background sound signal in the audio signal.

[0037] It should be noted that in this embodiment, the pressing and rotating operations of the rotatable button can be performed in conjunction or independently. In the coordinated state, the volume of the human voice signal or background sound signal in the audio signal can be adjusted only after the rotatable button is pressed and the second audio signal processing unit 112 is connected in the circuit. In the independent control state, the pressing and rotating operations of the rotatable button independently control the audio signal.

[0038] In this embodiment, a rotatable knob is used as a control unit, which can turn off or on the human voice signal or background sound signal in the audio signal, and can also adjust the size of the human voice signal or background sound signal in the audio signal, further improving the user experience of the product.

[0039] Please refer to Figure 5 , which shows that in one embodiment of the present application, the control unit is a touch button 1011 provided on the housing of the electronic device. Triggering the touch button 1011 can turn on or off the human voice signal or background sound signal in the audio signal. Figure 5 As shown, the touch button 1011 can be disposed in the touch panel 101. In addition, the touch panel can be disposed on any wall of the electronic device 100, not limited to the front wall, top wall, side wall, etc.

[0040] Furthermore, if Figure 6 As shown, the control unit also includes a control subunit 1012, which is a touch sub-button. Triggering the touch sub-button 1012 can adjust the size of the human voice signal or background sound signal in the audio signal. Specifically, when the user needs to use the electronic device to sing karaoke, click the touch button 1011 on the touch panel 101, and the touch sub-button 1012 pops up. For example, it includes "-" and "+". Clicking "-" can reduce the volume of the human voice in the audio signal, and clicking "+" can increase the volume of the human voice in the audio signal; or clicking "-" can reduce the volume of the background sound in the audio signal, and clicking "+" can increase the volume of the background sound in the audio signal. It should be noted that clicking "-" multiple times to the endpoint can reduce the volume of the human voice or background sound in the audio signal to 0. At this time, the audio signal only contains the human voice audio signal or the background sound audio signal, which makes it convenient for the user to perform vocal recording analysis when only the human voice audio signal is contained or to sing along when only the background sound audio signal is contained. Clicking the "+" button multiple times to the endpoint can adjust the volume of the human voice or background sound in the audio signal back to a normal level. At this time, the user switches from the human voice recording analysis mode or the sing-along mode to the audio appreciation mode.

[0041] Please refer to Figure 7 In other embodiments, touch button 1011 may display "Karaoke Mode," and the user can click it to enter the settings interface. In the settings interface, the user can select "Remove Vocals" or "Remove Background Sounds" and adjust the settings as needed. After the adjustments are made, the user can start playing a song by pressing the play button on the soundbar and enjoy karaoke.

[0042] Please refer to Figure 8, which shows a schematic diagram of the wireless connection between the integrated control unit 201 of the terminal device 200 and the electronic device 100. It should be noted that the terminal device 200 can also be connected to the electronic device 100 by wire. Specifically, the terminal device 200 can be an intelligent device installed with an APP that matches the electronic device 100, such as a mobile phone, tablet, personal PC, etc. The user can achieve effects such as removing human voice or background sound or adjusting human voice and background sound through the corresponding function blocks on the matching APP. When operating on the APP, the user first needs to download and install the APP that matches the electronic device on the mobile phone (such as the ULTIMEA APP corresponding to ULTIMEA soundbar) and connect the electronic device via Bluetooth or Wi-Fi. After the connection is successful, the user can select "K song mode" in the APP and enter the settings interface. In the settings interface, the user can also select the "remove human voice" or "remove background sound" options and adjust them as needed. After the adjustment is completed, the user can start playing the song through the play button on the APP and remotely control it through the mobile phone.

[0043] In addition, in one embodiment, the housing of the electronic device 100 is further provided with a receiving groove for receiving a microphone device connected to the audio of the electronic device, so that the microphone can be conveniently placed in the receiving groove of the electronic device 100 .

[0044] It should be noted that the electronic device in this application can be a speaker, a projector or a mobile screen, so that the speaker, the projector or the mobile screen can directly perform karaoke chorus.

[0045] Through the above methods, users can easily realize the karaoke function of speakers, projectors, or mobile screens, and perform various settings and operations through the control unit or app to meet different karaoke needs. The system integrates audio processing technology, and users can set it up through the control unit or app to achieve the function of removing vocals or background sounds. The vocal removal function can help users remove the vocals of the original song, retaining only the accompaniment, making it easier for users to sing along or sing together.
