Embodiment 1

[0026] Such as Figure 1 to Figure 4 As shown, the key supporting frame includes a supporting plate 1 for supporting the housing 100 of the playing guidance device.

[0027] The top surface of the supporting plate 1 extends upwards with two support rods 12 for supporting the back of the housing 100 of the playing guidance device, and a positioning groove that can match the positioning groove at the bottom of the housing 100 of the playing guidance device. The protrusion 11 and the two support rods 12 are respectively located on the left and right sides of the supporting plate 1 , and the positioning protrusion 11 is located between the two support rods 12 .

[0028] As we all know, whether it is an electronic organ or a piano, such as Figure 4 As shown, there are black keys 201 and white keys 202 on the keys 200, and the distribution is that the white keys 202 are at the bottom, the black keys 201 are above the white keys 202, and the arrangement of the black keys 201 from l...

Embodiment 2

[0035] Such as Figure 5 to Figure 7 As shown, the difference between this embodiment and the first embodiment is that some circuit modules of the playing guidance device are integrated on the supporting plate. The details are as follows:

[0036] The key supporting frame includes a supporting plate 2 for supporting the casing 300 of the playing guidance device.

[0037] The top surface of the supporting plate 2 extends upwards with two support rods 22 for supporting the back of the housing 300 of the playing guidance device, and a positioning groove that can match the positioning groove at the bottom of the housing 300 of the playing guidance device. The protrusion 21 and the two support rods 22 are respectively located on the left and right sides of the supporting plate 2 , and the positioning protrusion 21 is located between the two support rods 22 .

[0038] The bottom surface of the supporting plate 2 extends downward with a positioning block 24, the width of the positi...

Embodiment 3

[0044] Such as Figure 8 and Figure 9 As shown, the difference between the present embodiment and the second embodiment lies in the structure of more functional component slots. The details are as follows:

[0045] The top surface of the supporting plate 2 also extends upwards with two functional component slots 26, and circuit contacts 261 are installed in the functional component slots 26, and the circuit contacts 261 are electrically connected with the single-chip microcomputer 303; a functional component The socket 26 is plugged with a functional component insert 400 , and the electrical contact piece 401 of the functional component insert 400 is connected with the circuit contact 261 .

[0046] The functional component insert 400 can be a memory card or a power module or a sound player.

[0047] That is to say, the power socket 305 of the second embodiment is canceled in this embodiment, and the functional component socket 26 is used to replace it. When the functiona...

Abstract

The invention relates to a bearing type support frame for a key. The bearing type support frame comprises a bearing surface plate, wherein the bearing surface plate is used for bearing a shell of a playing instruction device, the top face of the bearing surface plate extends upwards to form two support rods which are used for supporting the back of the shell of the playing instruction device, a positioning lug which can match with a positioning groove at the bottom of the shell of the playing instruction device is arranged on the top face of the bearing surface plate, the two support rods are respectively located on the left side and the right side of the bearing surface plate, the positioning lug is located between the two support rods, the bottom face of the bearing surface plate extends downwards to form a positioning clamping block, the width of the positioning clamping block matches with a gap between a third black key and a second black key of the key, and the bottom face of the bearing surface plate contacts with the black keys. Since the positioning lug matches with the positioning clamping block, a light emitting diode display panel of the playing instruction device can be accurately aligned with the key, and the problem of deviation in the prior art is solved.

Description

technical field [0001] The invention relates to a supporting frame structure, in particular to a supporting frame for supporting a piano auxiliary guiding device. Background technique [0002] With the progress of society, people pay more and more attention to spiritual life. For example, more and more people learn to play the piano, electronic organ and so on. When learning to play, you must be able to read the score, find the correct key, and consider the beat while playing the existing beat. To play smoothly, these three processes must be carried out at the same time, without a long process. Time-trained people can't do it. Beginners are often not familiar with the score and keys of the piano, they cannot control the rhythm, and they cannot be corrected in time when they make mistakes, which makes the process of playing boring and inefficient, and it is difficult to experience the joy of playing beautiful music by themselves. [0003] In view of this, the applicant inv...
