Description

Technical Field

[0001] The utility model relates to the technical field of electric blowpipes, in particular to an octave wheel structure for an electric blowpipe. Background Art

[0002] Wind synth is a musical instrument invented in 1970. The playing methods are divided into conventional playing methods and unconventional playing methods. Conventional playing methods are playing methods that are exactly the same as those of acoustic wind instruments. For example, long notes, legato, tonguing, and legato tonguing, these playing methods are relatively simple to implement on both acoustic wind instruments and wind synths, and have a wide range of applications. There are also some playing methods that are difficult to implement on acoustic wind instruments, or even impossible to play, but are easier to complete on wind synths, such as: big jumps, super-range performance, glissando, timbre change, etc., which are also classified as conventional playing methods. Unconventional playing methods are that there are some playing methods that do not exist on acoustic wind instruments, and the implementation methods of wind synths are relatively complicated, and even require the help of external software and other tools to achieve them, such as: stacking, double notes, sustained notes, singing while blowing, mapping, etc., which are classified as unconventional playing methods.

[0006] Preferably, the length of the roller shaft is slightly longer than the length of the roller body, so that the roller body can stably rotate on the roller shaft.

[0007] Preferably, the roller shaft is coated with conductive paste, and the conductive paste is used to stabilize the electrical connection between the roller body and the roller shaft.

[0008] The utility model provides an electric blowpipe octave wheel structure which is not only convenient to install but also has good contact, simple operation and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.

[0013] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0014] See also Figure 1 and Figure 2 The utility model provides an electric blowpipe octave wheel structure, the electric blowpipe octave wheel structure comprising:

[0015] An octave side panel 1, wherein two octave side panels 1 are provided and are symmetrically distributed, and through holes are opened on the two octave side panels 1, and a plurality of through holes are opened; a roller shaft 2, which is arranged between the two octave side panels 1 and is flush with the through holes, threaded holes are opened at both ends of the roller shaft 2, and a roller body 3 is sleeved on the roller shaft 2. The roller body 3 can stably rotate on the roller shaft 2; a roller screw 4, which can pass through the through hole and be threadedly connected to the roller shaft 2, and is used to fix the roller shaft 2 between the two octave side panels 1; a socket strip 5, which is fixedly set on the octave side panel 1, and the socket strip 5 is connected to the roller screw 4 through a wire and copper foil; a pressure block 6, which is arranged in conjunction with the octave side panel 1, and a bolt hole is opened on the pressure block 6, and a bolt 7 is arranged in conjunction with the bolt hole, and the pressure block 6 and the bolt 7 are used to fix the octave side panel 1.

[0016] The roller body 3 is the component that the user directly contacts. The roller body 3 is in contact with the roller shaft 2, and the roller shaft 2 is in contact with the roller screw 4. The roller screw 4 is pressed on the copper foil of the octave side panel 1, and a wire is led to a power strip 5. The power strip 5 has a flat cable connected to the corresponding flat cable on the mainboard, and finally connected to the pin of a touch control chip. The pressing block 6 and the bolt 7 can conveniently install the octave side panel 1 on the electric blowpipe.

[0017] like Figure 1and Figure 2 As shown, as a preferred embodiment of the present utility model, the length of the roller shaft 2 is slightly longer than the length of the roller body 3 , so that the roller body 3 can stably rotate on the roller shaft 2 .

[0018] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the utility model, the roller shaft 2 is coated with conductive paste, and the conductive paste is used to stabilize the electrical connection between the roller body 3 and the roller shaft 2 .

[0019] The length of the roller shaft 2 is slightly longer than that of the roller body 3, for example 0.4 mm, so that the roller body 3 will not be clamped by the two octave side plates 1 and can rotate freely. The roller shaft 2 is coated with conductive paste to ensure stable electrical connection between the roller body 3 and the roller shaft 2.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
