As shown in FIG. 1 , the violin display has a control device 100 and a fingerboard display 110 , wherein the control device 100 has a control unit 101 , an audio processing unit 102 , a display panel 103 , an input module 104 , And a USB interface 105.

The control unit 101 determines its operating mode according to one of the sensing signals output by the input module 104. The working mode includes: transmitting a bit of auxiliary line state data to the fingerboard display 110; driving the audio processing unit 102 to perform scale detection; driving the audio processing unit 102 to perform recording; and transmitting an operation option screen To the display panel 103; transmitting a scale data to the display panel 103; and driving the USB interface 105 for an external USB device to download a recording file. The control unit 101 preferably includes a microcontroller.

The audio processing unit 102 has a scale detecting unit and a recording unit controlled by the control unit 101 to perform scale detection and/or recording to generate the scale data and/or the sound file.

The display panel 103 is configured to: display the operation option screen for the user to set the operation mode of the control unit by operating the input module 104; or display the scale information according to the scale data. The options of the operation option screen include: transmitting the position guide line profile data; performing scale detection; performing recording; transmitting scale data; and downloading the recording file. The display panel 103 is, for example but not limited to, an electrophoretic display, a microelectromechanical display, a cholesteric liquid crystal display, an electrowetting display, or a liquid crystal display.

The input module 104 can be a keyboard device or a touch module for outputting the sensing signal according to a pressing input operation. The touch module is, for example, but not limited to, a resistive touch module, a capacitive touch module, an optical touch module, an acoustic wave touch module, or a pressure sensing touch module.

The USB interface 105 is used for an external USB device to download a recording file for the user to listen after playing, and to improve his playing skills. The external USB device can be an MP3 or MP4 device.

The fingerboard display 110 is configured to display a picture according to the position guide line profile data. The fingerboard display 110 can be, for example but not limited to, an electrophoretic display, a microelectromechanical display, a cholesteric liquid crystal display, an electrowetting display, or a liquid crystal display.

FIG. 2 is a schematic diagram showing the implementation of the violin display of the present case on a violin 200. As shown in FIG. 2, the control device 100 is placed approximately at the center of the violin 200, and the fingerboard display 110 is placed on the fingerboard of the violin 200. The user can operate the control device 100 to cause the fingerboard display 110 to display a specific fingerboard position auxiliary line state to meet different learning stages; or to cause the control device 100 to display the detected scale. Information; or perform a recording job; or download a recording file.

In summary, the violin display of the present invention can display the scale information issued by the violin in addition to the position of the auxiliary guide line, and/or record the performance process, which not only solves the problem encountered by the violin beginners. The problem also provides additional convenience.

The disclosure of the present invention is a preferred embodiment, and any part of the modification or modification resulting from the technical idea of the present invention can be easily inferred by those skilled in the art, without departing from the scope of the patent of the case, such as replacing the control device. 100 is placed on the violin, and the fingerboard display 110 is replaced by an LED module.

In summary, this case, regardless of its purpose, means and efficacy, is showing its technical characteristics that are different from the conventional ones, and its first invention is practical and practical, and it is also in compliance with the patent requirements of the invention. I will be granted a patent at an early date.
