The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 and 2, an electronic blow tube 100 according to an embodiment of the present invention includes a body 10, a flexible touch panel 20 attached to the body 10, a button indicating module 30 attached to the flexible touch panel 20, and a body indicator body 30 disposed on the body Controller 40 within 10. The button indicating module 30 includes a plurality of button indicators 31 disposed on the flexible trackpad 20, and the controller 40 controls the tones according to the touch signals generated by the flexible trackpad 20 when the button indicators 31 are touched. In this embodiment, a plurality of button indicators 31 are disposed on the flexible touch panel 20, and different tone indicators can be controlled by different button indicators 31. That is, the present embodiment utilizes the flexible trackpad 20 and The combination of the plurality of button indicators 31 replaces the physical buttons to extend the life of the electronic torch 100.

In the embodiment, the flexible touch panel 20 is attached to the outer wall of the body 10 . The flexible touch panel 20 has a complete annular cross section that surrounds the outer wall of the body 10. In addition, the cross section of the flexible touch panel 20 may not necessarily form a complete ring shape, but may be broken at a specific position, or even formed into a semi-annular shape, depending on the requirements. The flexible touch panel 20 is also formed by splicing a plurality of separate flexible touch panels to reduce manufacturing costs. Of course, in other embodiments, the flexible touch panel 20 can also be attached to the inner wall of the body 10 . The flexible touch panel 20 can be made of a transparent flexible material, such as PVC, PET, ARM, etc., so that the body 10 can be set to a circular shape, a square shape, a horn shape or the like according to actual needs. In use, the flexible trackpad 20 senses the touch of the corresponding button indicator 31 position and then feeds the touch information back to the controller 40. The controller 40 determines which button indicator 31 is pressed according to the touch signal. Then the control emits the corresponding tone.

In the present embodiment, the button indicator 31 is a print pattern provided on the flexible touch panel 20. Different types of printed patterns correspond to different types of wind instruments, and different print patterns can be distinguished by different colors, lines, sizes, patterns, etc., and the printed patterns may partially overlap. For example, as shown in FIG. 3, the solid circle corresponds to a six-hole flute, the dotted circle corresponds to a flute, and the solid circle has a partial overlap with the dashed circle. Of course, in other embodiments, the button indicators corresponding to different types of wind instruments can also be displayed in different positions. In this case, the shape, color, and the like of the button indicators corresponding to different types of wind instruments may be the same or different. For example, a plurality of print patterns corresponding to the six-hole flute are disposed on one side of the electron blow tube 100, and a plurality of print patterns corresponding to the flute are disposed on the other side of the electron blow tube 100, and the plurality of print patterns corresponding to the six-hole flute correspond to the flute.

Of course, if several printed patterns overlap each other, it is also possible to provide light-emitting diodes only at the overlap, and different colors can be distinguished by the light-emitting diodes to distinguish different musical instrument types. After determining that the user selects one type of wind instrument, the controller 40 lights up a plurality of light-emitting diodes corresponding to a set of printing patterns corresponding to the selected wind instrument type, while keeping the other light-emitting diodes in a non-lighting state. In this way, the user can quickly determine which printed patterns are effective to touch. In addition, it is also possible to indicate the position of the button only by the light emitting diode without using a printed pattern. At this point, the LED is As the button indicating module 30.
