The following detailed description of the invention refers to the accompanying drawings.

Fig. 1 shows a schematic diagram of an electronic device 100 for processing a performance signal according to an embodiment of the present invention.

As shown in fig. 1, the electronic apparatus 100 includes at least two functional circuit boards, which are arranged in a split manner. The number of the functional circuit boards can be specifically set according to needs, and for example, the number of the functional circuit boards can be 2, 3, 5 or 8. The split arrangement herein means that all functional circuit boards are independent and separable from each other, rather than on a single integrated circuit board. For simplicity of description, fig. 1 shows only an exemplary case including 4 functional circuit boards.

In one embodiment, each of the functional circuit boards may have one functional circuit disposed thereon, wherein at least two functional circuits on at least two functional circuit boards include at least one signal detection circuit and at least one signal processing circuit. For example, when two functional circuit boards are included, the at least two functional circuits may include one signal detection circuit and one signal processing circuit. To extend the functionality of the electronic device, in one or more embodiments, the functional circuitry may also include, for example, display circuitry, memory circuitry, and sound circuitry.

When 3, 4 or more functional circuit boards are included, the at least two functional circuits may include a plurality of signal detection circuits and one signal processing circuit, and may also include a plurality of signal detection circuits and a plurality of signal processing circuits. In addition, the at least two functional circuits may further include a plurality of signal detection circuits, a plurality of signal processing circuits, and one display circuit. Further, the at least two functional circuits may further include a signal detection circuit, a signal processing circuit, a display circuit, a storage circuit, and a sound generation circuit.

In the present embodiment, it can be set that 4 of the functional circuit boards include the first signal detection circuit board 101, the second signal detection circuit board 102, and the third signal detection circuit board 103 on which the signal detection circuits are arranged, and the signal processing circuit board 104 on which the signal processing circuits are arranged.

In one embodiment, each of the signal detection circuits described above may be used to detect at least one type of performance signal from an external device. The performance signals may be generated by the external device based on different triggering manners, for example, the performance signals may at least include performance signals generated by the external device based on striking (such as performance signals generated by striking a drumhead, a gong, a cymbal, a marimba or a xylophone), performance signals generated by the external device based on pressing (such as performance signals generated by pressing strings of a piano or an accordion), or performance signals generated by the external device based on touching.

The performance signal may also be different depending on the type of external device. For example, when the external device includes a key module (including at least keys and sensors used in cooperation therewith), the performance signal may include a piano-like performance signal. Further, the piano type performance signal may include performance signals of a piano, a xylophone, a tremolo, a marimba, or the like, depending on the type of the specific piano.

When the external device includes a drumhead module (including at least a drumhead and sensors used in cooperation therewith), the performance signals may include drum-like performance signals. Further, the drum-like performance signals may include performance signals of a drum kit, a tambourine, a bass drum, or the like, depending on the type of the specific drum. When the external device includes a gong-type performance module (including at least a gong face), the performance signal may include a gong-type performance signal. Further, when the gong is a gong, the gong-type performance signal may include a performance signal of the gong.

In addition, when the external apparatus includes a hi-hat performance module (including at least a hi-hat piece), the performance signals may include hi-hat performance signals. Further, the hi-hat type performance signal may include a performance signal of a dot-hi-hat, a hanging-hi-hat, or the like, depending on the type of specific hi-hat. Further, when the external device includes a stringed instrument playing module (including at least strings), the playing signal may include a stringed instrument playing signal. Further, the stringed instrument performance signal may include a performance signal of a violin, viola, cello, or the like, depending on the type of the specific stringed instrument.

When a plurality of signal detection circuits are included in the electronic apparatus 100, the number of performance modules detected by each signal detection circuit and the correspondence relationship between the detection circuits and the performance modules may be set as necessary. For example, when the electronic apparatus 100 in the present embodiment is used to process performance signals from a piano, the signal detection circuit on the first signal detection circuit board 101 thereof can detect performance signals of the key modules corresponding to 1 st to 20 th keys, the signal detection circuit on the second signal detection circuit board 102 can detect performance signals of the key modules corresponding to 21 st to 50 th keys, and the signal detection circuit on the third signal detection circuit board 103 can detect performance signals of the key modules corresponding to 51 st to 88 th keys; alternatively, the signal detection circuit on the first signal detection circuit board 101 may detect the performance signals of the key modules corresponding to the 1 st to 44 th keys, the signal detection circuit on the second signal detection circuit board 102 may detect the performance signals of the key modules corresponding to the 45 th to 70 th keys, and the signal detection circuit on the third signal detection circuit board 103 may detect the performance signals of the key modules corresponding to the 71 th to 88 th keys.

In one embodiment, each of the at least one signal processing circuit may be electrically connected to at least one of the signal detection circuits and configured to process a performance signal of at least one of the signal detection circuits to obtain a corresponding output signal. In one implementation scenario, the signal processing circuitry may include at least a processor.

In the embodiment shown in fig. 1, the signal processing circuit on the signal processing circuit board 104 may be electrically connected to the signal detection circuits on the first signal detection circuit board 101, the second signal detection circuit board 102 and the third signal detection circuit board 103, and is configured to process performance signals of these signal detection circuits to obtain corresponding output signals.

Taking the case that the signal detection circuit on the first signal detection circuit board 101 detects the performance signals of the key modules corresponding to the 1 st to 20 th keys of the piano, the signal detection circuit on the second signal detection circuit board 102 detects the performance signals of the key modules corresponding to the 21 st to 50 th keys of the piano, and the signal detection circuit on the third signal detection circuit board 103 detects the performance signals of the key modules corresponding to the 51 st to 88 th keys of the piano as an example, the signal processing circuit can process the performance signals of any one of the key modules corresponding to the 1 st to 20 th keys of the piano according to the signal detection circuit on the first signal detection circuit board 101 to obtain the corresponding output signals. Similarly, the signal processing circuit can also process the performance signal of any one of the key modules corresponding to 21 st to 50 th keys of the piano according to the signal detection circuit on the second signal detection circuit board 102 to obtain a corresponding output signal. In addition, the signal processing circuit can also process the performance signal of any one of the key modules corresponding to the 51 st to 88 th keys of the piano according to the signal detection circuit on the third signal detection circuit board 103 to obtain a corresponding output signal.

As shown in fig. 1, the signal detection circuit and the signal processing circuit may be wirelessly connected, thereby facilitating simplification of wiring between the respective functional circuit boards in the electronic device. The wireless connection may include, but is not limited to, for example, one or more of a bluetooth connection, an infrared connection, and a WIFI connection. In another embodiment, the signal detection circuit and the signal processing circuit can be connected by wires, so that reliable connection between various functional circuit boards in the electronic equipment can be realized. The wired connection may include, but is not limited to, one or more of a serial connection, a fiber optic connection, and a USB connection, for example.

The electronic equipment of the scheme comprises a plurality of independent functional circuit boards, and the functional circuit boards are arranged in a split mode, so that the functional circuit boards can be flexibly electrically combined and/or structurally arranged according to electrical and/or structural requirements. For example, when processing a performance signal of a piano, processing may be performed using an electronic device including 3 signal detection circuit boards and 1 signal processing circuit board, and processing may also be performed using an electronic device including 2 signal detection circuit boards and 2 signal processing circuit boards. When the related display is required, a display circuit board (on which a display circuit is arranged) may be added to the electronic device. Further, when sound is required to be generated, a storage circuit board (on which a storage circuit is arranged) and a sound generation circuit board (on which a sound generation circuit is arranged) can be added in the electronic device, so that corresponding sound source data can be searched in the storage circuit according to the detected performance signal, and sound is generated through the sound generation circuit according to the sound source data.

It is understood that when processing performance signals from the same kind of external devices (e.g., piano and marimbap), it is possible to increase or decrease the number of corresponding function circuit boards according to the number of performance modules of the external devices before and after replacement without replacing the function circuit boards (the same function circuit may be applied to the same kind of external devices). For example, the electronic device 100 in fig. 1 can reduce only one signal detection circuit board (since there are fewer keys than pianos) when changing from processing a performance signal from a piano to processing a performance signal from a marimba, i.e., can make the electronic device meet the demands of different electronic musical instruments by such a simple increase and decrease operation.

In the aspect of structural arrangement, the functional circuit boards arranged in a plurality of split modes can be arranged in different modes according to the scheme, so that different structural requirements are met. For example, when the electronic device is required to be easily arranged, connected, maintained, inspected and disassembled, a plurality of functional circuit boards included therein may be arranged at the same level. When the electronic device is required to be portable and transportable, a plurality of functional circuit boards included therein may be stacked. In addition, the function circuit on each function circuit board can be reasonably distributed by adopting a split type arrangement mode, so that the efficiency of circuit design is improved. The promotion of design efficiency makes can change the function circuit on arbitrary function circuit board alone and does not influence other circuits to can make things convenient for the redesign of circuit board. Furthermore, by adopting the split functional circuit board, the functional circuit can be pertinently replaced and maintained when the functional circuit is in fault, so that the higher maintenance cost caused by replacing the whole circuit board due to the fault of the circuit board can be reduced.

In summary, the electronic device of the present disclosure includes a plurality of independent functional circuit boards, and the functional circuit boards are arranged in a split manner, so that the functional circuit boards can be flexibly electrically combined and/or structurally arranged according to electrical and/or structural requirements. The flexible electrical combination and/or structural arrangement enables the electronic device to be easily modified, carried and transported, while reducing maintenance costs, thereby enabling the electronic musical instrument using the electronic device to have corresponding advantages.

As can be seen from the foregoing description of the embodiments, at least two functional circuit boards in the electronic device may be arranged differently (arranged in the same horizontal plane or stacked arrangement, etc.) according to different structural requirements. The following detailed description of different structural arrangements of the functional circuit boards will be provided with reference to fig. 1 to 5.

First, the present solution will be described with reference to fig. 1 and 2, in which a plurality of functional circuit boards in an electronic device are arranged on the same horizontal plane.

Fig. 1 shows a case where 4 functional circuit boards are horizontally arranged on the same horizontal plane (as indicated by a dashed box 105 in the figure). In this embodiment, the 4 functional circuit boards (the first signal detection circuit board 101, the second signal detection circuit board 102, the third signal detection circuit board 103, and the signal processing circuit board 104) may be in a rectangular shape having the same length and width, respectively. In the present embodiment, the 3 signal detection circuit boards (the first signal detection circuit board 101, the second signal detection circuit board 102, and the third signal detection circuit board 103) may be arranged in a row at an equal interval, and the signal processing circuit board 104 may be arranged in another row parallel to the above-mentioned one row (parallel here may be understood as a center line of the functional circuit boards of the two rows passing through the short sides thereof being parallel), and aligned with the leftmost signal detection circuit board (the first signal detection circuit board 101). Arranging all the signal detection circuit boards in a row may facilitate the wiring neatly when the signal detection circuit boards and the signal processing circuit board 104 are wired.

It is to be understood that the manner in which the above-mentioned functional circuit boards are horizontally arranged on the same horizontal plane is only exemplary and not limiting, and those skilled in the art can modify the same as required, for example, the above-mentioned 4 functional circuit boards can also be arranged in regular shapes or irregular shapes such as triangle, rectangle or circle on the horizontal plane as a whole. In addition, the above-mentioned 4 functional circuit boards may also be arranged in the same row, or the signal processing circuit board 104 may be aligned with other signal detection circuit boards (for example, with the middle or rightmost signal detection circuit board). Furthermore, the 3 signal detection circuit boards can be arranged at unequal intervals, and the circuit boards with different functions can be unequal in size and different in shape. It is understood that, the arrangement of 4 functional circuit boards horizontally arranged on the same horizontal plane is described above, and when more or less functional circuit boards are included, they may be reasonably arranged by referring to the above-mentioned manner, and detailed description thereof is omitted here.

Fig. 2 shows a case where 4 functional circuit boards 201 are vertically arranged on the same horizontal plane (as indicated by a dashed line frame 202 in the figure), wherein the 4 functional circuit boards 201 may be rectangular in shape with equal length and width. As shown in fig. 2, the short sides of the 4 functional circuit boards 201 are parallel to the horizontal plane, the long sides are perpendicular to the horizontal plane, so that the planes thereof are perpendicular to the horizontal plane and a plurality of functional circuit boards are arranged in a row at equal intervals. In short, 4 functional circuit boards 201 are arranged in parallel in a row in the same vertical manner on the same horizontal plane. In the present embodiment, when the electronic apparatus 200 includes only one signal processing circuit board, it may be disposed at one of two positions (e.g., at the 2 nd position on the left side in the drawing) in the center in order to facilitate its wired connection with other functional circuit boards (e.g., signal detection circuit boards).

It is understood that the manner in which the above-mentioned functional circuit boards 201 are vertically arranged on the same horizontal plane is merely exemplary and not limiting, and those skilled in the art can also modify the same as required, for example, the above-mentioned 4 functional circuit boards 201 can also be arranged at unequal intervals. In addition, the long sides of the 4 functional circuit boards 201 may be parallel to the horizontal plane or the long sides of some functional circuit boards (for example, 2 functional circuit boards) may be parallel to the horizontal plane, and the short sides of the rest functional circuit boards (for example, the other 2 functional circuit boards) may be parallel to the horizontal plane. Further, the 4 functional circuit boards 201 may also be arranged in two parallel rows as shown in fig. 1, and the included angle between the plane and the horizontal plane may also be other angles, such as 30 °, 60 °, or 70 °.

Besides the parallel arrangement, the 4 functional circuit boards 201 may also be arranged in a non-parallel manner, for example, a part of the functional circuit boards 201 are horizontally rotated by a certain angle, so that the planes of the functional circuit boards 201 form a non-zero included angle (for example, 90 °). In addition, the included angle between at least the functional circuit boards 201 and the horizontal plane may be changed, so that 4 functional circuit boards 201 are not parallel, for example, the included angle between a part of the functional circuit boards 201 and the horizontal plane is 30 °, and the included angle between the rest of the functional circuit boards 201 and the horizontal plane is 60 °, and the like. Further, it is also possible to arrange the plurality of functional circuit boards 201 vertically but not in parallel by a combination of the above two.

In addition, as described in the foregoing embodiment, the positions of the 4 functional circuit boards 201 may be interchanged. Further, the sizes of the different functional circuit boards 201 in the 4 functional circuit boards 201 may not be equal, and the shapes may be different. It is understood that, only the arrangement mode that 4 functional circuit boards are vertically arranged on the same horizontal plane is described above, when more or less functional circuit boards are included, reasonable arrangement can be made by referring to the above mode, and detailed description is omitted here.

The above description has been given, in connection with the embodiments, of the case where all the functional circuit boards are arranged horizontally or vertically on the same horizontal plane. In one or more embodiments, some of the plurality of functional circuit boards may be arranged horizontally in at least one horizontal arrangement, and the rest may be arranged vertically in at least one vertical arrangement. It can be understood that arranging a plurality of functional circuit boards on the same horizontal plane can facilitate the layout, connection, maintenance detection, disassembly and assembly, etc. of the functional circuit boards. The present solution will be described with reference to fig. 3-5 for stacking a plurality of functional circuit boards in an electronic device.

Fig. 3 schematically shows a stacked arrangement of 4 functional circuit boards 301, wherein the 4 functional circuit boards 301 have a rectangular shape with equal length and width. As shown in fig. 3, the above-mentioned 4 functional circuit boards 301 are arranged horizontally and aligned in the center (long side and long side are aligned, short side and short side are aligned). This arrangement makes it possible to make the area of the electronic apparatus 300 only the area of one functional circuit board 301, so that the electronic apparatus 300 can be conveniently carried and transported. In addition, the 4 functional circuit boards 301 may be arranged at equal intervals. In this embodiment, when the electronic device 300 includes only one signal processing circuit board, it may be disposed in one of two central positions (e.g., disposed at the upper 2 nd layer in the figure) in order to facilitate its wired connection with other functional circuit boards 301 (e.g., signal detection circuit boards).

It is understood that the above-described centrally aligned stacking arrangement is merely exemplary and not limiting, and may be modified as desired by one skilled in the art, for example, the positions of the plurality of functional circuit boards 301 may be interchanged as described in the foregoing embodiments. Alternatively, the 4 functional circuit boards 301 may be arranged at unequal intervals. In addition, the 4 functional circuit boards 301 may not have aligned long sides and short sides. Further, the 4 functional circuit boards 301 may not be equal in size and may have different shapes. It is understood that only the arrangement of the horizontal stack of 4 functional circuit boards 301 is described above, and when more or less functional circuit boards are included, the arrangement can be reasonably made by referring to the above-mentioned manner, and the detailed description is omitted here.

Fig. 4 schematically shows another stacked arrangement of 4 functional circuit boards 401, wherein the 4 functional circuit boards 401 are rectangular with equal length and width. As shown in fig. 4, 4 functional circuit boards 401 are arranged horizontally, with long sides corresponding to long sides and short sides corresponding to short sides, and are sequentially staggered rightward (rightward in the long-side direction) by equal distances from the bottom toward the center of the upper functional circuit board 401 to form a staggered stacked arrangement between multiple layers. Reference numeral 400 in the figure is an electronic device.

It is understood that the above-mentioned staggered stacking arrangement is only exemplary and not restrictive, and those skilled in the art may modify the above arrangement as required, for example, the centers of all the functional circuit boards 401 may be staggered by equal or unequal distances toward the left side in the figure, toward the inside of the paper or toward the outside of the paper, or the centers of different functional circuit boards 401 may be staggered by equal or unequal distances toward different directions. In addition, as described in the foregoing embodiment, the positions of the 4 functional circuit boards 401 may be interchanged. Further, the different functional circuit boards 401 may have different sizes and different shapes. It is understood that only the arrangement of 4 functional circuit boards 401 in staggered stacking is described above, and when more or less functional circuit boards are included, the arrangement can be reasonably made by referring to the above-mentioned manner, and the detailed description is omitted here.

Fig. 5 schematically shows another stacking arrangement of 6 functional circuit boards 501, in which the 6 functional circuit boards 501 have rectangular shapes with equal length and width. As shown in fig. 5, three of the 6 functional circuit boards 501 are horizontally stacked and arranged at the bottom, long and short sides are respectively aligned (long side and long side are aligned, short side and short side are aligned) and equally spaced, 4 th and 5 th functional circuit boards 501 are horizontally stacked and arranged at the top, long and short sides are respectively aligned and equally spaced, and long and short sides of the 5 functional circuit boards 501 at the top and bottom are also aligned. The 6 th functional circuit board 501 is perpendicular to its top and bottom functional circuit boards 501. In this embodiment, when the electronic device 500 includes only one signal processing circuit board, the vertical functional circuit board 501 may be a signal processing circuit board in order to facilitate the wired connection with other functional circuit boards 501 (e.g., signal detection circuit boards).

It is understood that the above-mentioned arrangement of hybrid stacks is only exemplary and not restrictive, and those skilled in the art may modify the arrangement as needed, for example, the positions of the 6 functional circuit boards 501 may be interchanged as described in the foregoing embodiments. In addition, it is also possible to vertically arrange more layers of the functional circuit boards 501, for example, it is also possible to vertically arrange the functional circuit boards 501 of the topmost and bottommost layers. The specific arrangement of the vertically arranged functional circuit board 501 can refer to the description of the foregoing embodiments, and is not described in detail here.

Further, the 5 horizontally arranged functional circuit boards 501 may be arranged at unequal intervals, and at least some of the 5 functional circuit boards 501 may be arranged in a staggered manner as shown in the foregoing embodiments. In addition, the 6 functional circuit boards 501 may not be equal in size and may have different shapes. It is understood that only the arrangement of the mixed stack of 6 functional circuit boards 501 is described above, and when more or less functional circuit boards are included, the arrangement can be reasonably made by referring to the above-mentioned manner, and the detailed description is omitted here.

The arrangement of the plurality of functional circuit boards in the electronic device is described above with reference to the embodiments. It is to be understood that the above-described arrangements of the embodiments are only exemplary and not restrictive, and those skilled in the art may combine or modify the above-described arrangements as required to meet different requirements under the guidance of the above-described embodiments. For example, the functional circuit boards in the electronic device may be divided into multiple groups, and the different groups may be arranged in the same or different arrangement manners as described in the foregoing embodiments. For example, when the functional circuit boards are divided into three groups, the three groups may each be arranged in the arrangement described in fig. 3. In addition, the three groups of functional circuit boards may be arranged in the arrangement described in fig. 2 for one group, in the arrangement described in fig. 4 for a second group, and in the arrangement described in fig. 5 for a third group. Alternatively or additionally, the sets of functional circuit boards may also enclose a predetermined shape, for example a cylindrical shape. Furthermore, a plurality of functional circuit boards can be respectively arranged on mounting surfaces with different heights.

Various arrangements of functional circuit boards in electronic devices have been described above in connection with embodiments. In order to ensure the stability of the electronic equipment when the electronic equipment is used (the performance signals are processed by the electronic equipment), at least part of the functional circuit boards in the plurality of functional circuit boards in the electronic equipment can be detachably connected. Based on this, in one embodiment, at least part of the functional circuit boards may be provided with first detachable connection structures for detachable connection between the functional circuit boards.
