[0017] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments and features in the embodiments of the present application may be combined with each other without conflict.

[0018] like Figure 1-Figure 2As shown, an optional embodiment of the utility model provides a music keyboard, including a base shell 1, a control circuit board 3 assembled in the base shell 1, and a keyboard module 2 assembled on the base shell 1 and connected to the control circuit board 3, the keyboard module 2 includes 15 note keys 21, and the note keys 21 are arranged in sequence according to the pitch. The music keyboard also includes a note adjustment module 30 electrically connected to the control circuit board 3 for single note adjustment of the note corresponding to the note key 21.

[0019] The embodiment of the utility model can form 2 or more scales by setting 15 note buttons 21, which meets the basic requirements of music arrangement and is also convenient for the miniaturization design of the music keyboard; in addition, the note adjustment module 30 is set to adjust the note buttons 21 by single notes, and the adjustment of the pitch is more detailed, so that the limited note buttons 21 can span more scales and match more music arrangement requirements. In the specific implementation process, the note adjustment module 30 can make the note button 21 rise or fall one scale by seven times of up-tuning or down-tuning, and still realize the function of the traditional scale adjustment module 32.

[0020] In another optional embodiment of the present invention, Figure 1 As shown, the note keys 21 are 14 full-tone keys 21a and 1 tonic key 21b, and the 14 full-tone keys 21a include 2 levels of complete scales or 2 levels of incomplete scales and 1 level of complete scale. This embodiment meets the basic requirements of playing and arranging music by setting 14 full-tone keys 21a and 1 tonic key 21b, and also facilitates the miniaturization of the music keyboard, taking into account the functionality and portability of the music keyboard; the 14 full-tone keys 21a can include 2 levels of complete scales or 2 levels of incomplete scales and 1 level of complete scale, matching more arranging requirements. In the specific implementation process, the composition of the 14 whole-tone keys 21a can be adjusted by the note adjustment module 30. When the first whole-tone key 21a is adjusted to the Do note, the 14 whole-tone keys 21a include two levels of complete scales. When the first whole-tone key 21a is adjusted to a note other than the Do note, the 14 whole-tone keys 21a include two levels of incomplete scales and one level of complete scale, thereby realizing an arrangement across three scales.

[0021] In another optional embodiment of the present invention, Figure 1 As shown, the note keys 21 are arranged in 3 rows, each row is arranged with 5 keys, and the tonic key 21b is arranged after the last full-tone key 21a. In this embodiment, the note keys 21 are arranged in 3 rows, each row is arranged with 5 keys, wherein the tonic key 21b is arranged after the last full-tone key 21a, which is consistent with the setting of traditional pianos and electronic keyboards and conforms to the playing habits of users.

[0022] In another optional embodiment of the present invention, Figure 2 As shown, the music keyboard also includes a scale adjustment module 32 electrically connected to the control circuit board 3 and used to increase or decrease the pitch of the note button 21. In this embodiment, the scale adjustment module 32 can increase the note button 21 by one scale at a time, thereby improving the adjustment efficiency.

[0023] In another optional embodiment of the present invention, Figure 1-Figure 2 As shown, a cross-shaped operation button 4 is provided on the base shell 1 corresponding to the note adjustment module 30 and the scale adjustment module 32. The upper key 321 and the lower key 323 of the cross-shaped operation button 4 are connected to the scale adjustment module 32 to respectively increase or decrease the scale of the note key 21. The left key 301 and the right key 303 of the cross-shaped operation button 4 are connected to the note adjustment module 30 to respectively decrease or increase the note of the note key 21. In this embodiment, the cross-shaped operation button 4 is provided to respectively connect the note adjustment module 30 and the scale adjustment module 32. Pressing the upper key 321 and the lower key 323 of the cross-shaped operation button 4 can be used to increase or decrease the scale of the note key 21. Pressing the left key 301 and the right key 303 of the cross-shaped operation button 4 can be used to increase or decrease the note of the note key 21. The scale adjustment has a certain correlation with the single note adjustment. The cross-shaped operation button 4 can integrate the two adjustment methods, which is more convenient for the user's adjustment operation. It can be understood that raising a note seven times in a row is equivalent to raising the scale once. Specifically, operating the left key 301 seven times in a row is equivalent to operating the down key 323 once, and operating the right key 303 seven times in a row is equivalent to operating the up key 321 once.

[0024] In another optional embodiment of the present invention, Figure 1-Figure 2 As shown, the base shell 1 is also provided with a sound hole 10, and the music keyboard further includes a speaker module 34 disposed in the base shell 1. In this embodiment, the sound hole 10 is provided in the base shell 1, and the speaker module 34 is provided to realize external playing of the music keyboard.

[0025] In another optional embodiment of the present invention, Figure 1-Figure 2 As shown, the music keyboard further includes an audio output port 36, and the base shell 1 is further provided with a volume adjustment button 33 for adjusting the playback or output volume of the speaker module 34 and the audio output port 36. The music keyboard in this embodiment can be connected to an audio playback device such as headphones through the audio output port 36 to achieve silent playing of music and adapt to more usage scenarios; in addition, a volume adjustment button 33 is provided to adjust the playback volume of the speaker module 34 and the output volume of the audio output port 36.

[0026] In another optional embodiment of the present invention, Figure 1-Figure 2As shown, the music keyboard further includes a timbre adjustment module 38, and a timbre switching button 381 is provided on the base shell 1 corresponding to the timbre adjustment module 38. In this embodiment, the timbre adjustment module 38 controls the timbre of each note key 21 after being struck and pressed, simulates various musical instrument sounds, and improves the richness of the arrangement timbre.

[0027] In another optional embodiment of the present invention, Figure 1-Figure 2 As shown, the music keyboard also includes a data transmission port 31 for connecting to an external device. The music keyboard in this embodiment can be connected to an external device through the data transmission port 31, which is convenient for software and firmware upgrades, and can also be used as a MIDI keyboard for performance and arrangement sampling.

[0028] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many variations without departing from the scope of protection of the purpose of the present invention and the claims, which all fall within the scope of protection of the present invention.
