[0056] The musical instrument interface area includes musical instrument input interfaces 24 which are all connected to the main control module.

[0057] Exemplarily, the musical instrument input interface 24 is used to connect to a data line plug of a user's acoustic guitar or electric guitar, so that the musical instrument audio generated by the user's musical instrument is transmitted to the main control module via the musical instrument input interface 24 .

[0058] It should be understood that the musical instrument input interface 24 may also be configured to connect to other musical instruments, and is not limited to acoustic guitars or electric guitars.

[0059] (2) Instrument switching area

[0060] The main control module configures two different circuits according to the acoustic guitar or electric guitar connected by the user, and the instrument switching switch is used to switch the two circuits to match the instrument connected to the instrument input interface 24. The instrument switching switches are all connected to the instrument switching module, and the instrument switching module is also connected to an instrument switching signal light 13 for indicating switching to an acoustic guitar or an electric guitar, so as to indicate the switched instrument.

[0061] Specifically, the instrument switching switch is a button that can only generate different electrical signals by pressing. When the user presses it with his hand (for example: pressing once to switch to the acoustic guitar circuit, pressing again to switch to the electric guitar circuit), different electrical signals will be generated in the instrument switching module, which will then be transmitted to the main control module. The main control module will switch to the acoustic guitar or electric guitar circuit according to the electrical signal and control the lighting state of the instrument switching signal light 13.

[0062] (3) Socket area

[0063] The socket area includes a microphone XLR 21 and an AUX socket 22; the microphone XLR 21 is used to input human voice audio, and the AUX socket 22 is used to receive file audio in the user's external storage device.

[0065] During use, the user inserts the charging cable of the corresponding plug into the charging port 4 to charge the rechargeable battery in the rechargeable battery box 3; when the user inserts the microphone data cable into the microphone XLR head 21, the user's vocal audio is processed by the microphone module and transmitted to the main control module; when the user inserts an external storage device (such as a mobile phone, tablet and other terminal devices) into the AUX socket 22 via a data cable, the main control module sends a file transfer request to the mobile phone, tablet and other terminal devices, and the audio file in the terminal device can be transmitted to the main control module.

[0066] (4) Effect control area

[0067] The effect control area is used to perform effect processing on instrument audio, vocal audio and file audio; the effect control area includes multiple sound effect control knobs 10 and distortion control knobs 11 for performing effect processing on instrument audio and file audio and multiple microphone knobs 19 for performing timbre processing on vocal audio.

[0068] Specifically, the body is provided with a sound effect control pedal 7 and a distortion control pedal 8, as well as a pedal signal light 9 corresponding to each pedal. The sound effect control pedal 7, the distortion control pedal 8, the pedal signal light 9, the sound effect control knob 10 and the distortion control knob 11 are all connected to the effect controller module, and the effect controller module is connected to the main control module.

[0069] The sound effect control pedal 7 and the distortion control pedal 8 are both pedals that can only generate different electrical signals by pressing. When the user presses with his foot (for example: press once to turn on, press again to turn off), different electrical signals will be generated on the corresponding pedals and transmitted to the main control module. The main control module controls the circuit of the effect controller module to turn on or off according to the electrical signal, and at the same time, the main control module controls the lighting state of the pedal signal light 9 according to the electrical signal.

[0070] The sound effect control knob 10 and the distortion control knob 11 are both knobs, and the adjustment range of the knobs is 0 to 10 levels. The degree of effect processing is adjusted by rotating the angle of the sound effect control knob 10 and / or the distortion control knob 11; at the same time, the angle at which each knob is located is not affected by the opening or closing of the effect controller module. When the effect controller module is turned on, the processing effect corresponding to the current angle of each knob will immediately generate a corresponding electrical signal directly in the effect controller module and transmit it to the main control module.

[0071] The microphone knob 19 is connected to the vocal processing module, and the vocal processing module is connected to the main control module. The user plugs the microphone data cable into the microphone XLR connector 21, and the user's vocal audio is input through the microphone XLR connector 21, processed by the microphone module into an electrical signal and transmitted to the main control module; at the same time, the user can rotate the microphone knob 19, and the microphone knob 19 generates an electrical signal in the vocal processing module and transmits it to the main control module, thereby performing timbre processing on the vocal audio.

[0072] The effect control area also includes a cabinet simulator for simulating the cabinet of musical instrument audio. The cabinet simulator is connected to the cabinet simulator module, and the cabinet simulator module is connected to the main control module.

[0076] The headphone jack 20 is connected to the headphone module, and the headphone module is connected to the main control module; the headphone jack 20 is used to connect the monitoring earphone. If the user inserts the connecting line of the music monitoring earphone into the headphone jack 20, the main control module transmits the audio signal to the user's monitoring earphone, so that the user can monitor the audio quality.

[0077] The OTG device interface 23 is connected to the main control module and is used to connect the internal recording device; when the user plugs the external internal recording device into the OTG device interface 23 via a data cable, the main control module sends a request to send data to terminal devices such as mobile phones and tablets (the corresponding permissions of the terminal device need to be obtained), and transmits the audio file to the user's internal recording device.

[0078] (6) Speaker 14 functional area

[0079] The speaker 14 functional area includes a speaker 14, which is used to directly play the audio processed by the main control circuit; the speaker 14 is connected to the speaker 14 module, and the speaker 14 module is connected to the main control module.

The Bluetooth module transmits the signal to the main control module for processing, and the main control module executes the command and plays the file audio in the device through the speaker 14.

[0080] Of course, if the user plugs the connection line of the music monitoring earphone into the earphone interface 20, the main control module immediately stops the speaker 14 from playing and transmits the audio signal to the user's monitoring earphone.

[0081] (7) Music Flipping Area

[0082] The music turning area is provided with a drum machine key and a plurality of music turning keys connected to the user terminal device via a Bluetooth module, for sending music turning and drum machine instructions to the user terminal.

[0083] The music-turning device pedal 5 and the drum machine pedal 6 are both pedals that can only generate different signals by pressing and pressing for different lengths of time. When the user steps on them with their feet and steps on them for different lengths of time, different electrical signals will be generated on the function key module and transmitted to the main control module, and then sent to the music-turning device and drum machine App on the mobile phone or tablet through the Bluetooth module (the corresponding permissions of the terminal device must be obtained) to be controlled to perform the corresponding music-turning and drum machine functions.
