[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] See also Figure 1 , the combined musical instrument 10 provided by the present invention is now described. The combined musical instrument 10 includes a keyboard instrument 100, a percussion instrument 200 and an associated component 300, wherein the keyboard instrument 100 and the percussion instrument 200 are distributed on the left and right sides; the keyboard instrument 100 includes a main keyboard 110, a first pressure sensor 120, a second pressure sensor 130, a processor 140 and a speaker 150, and the main keyboard 110 includes seven foot-operated buttons 111, each of which includes an upper end 1111 and a lower end 1112; the percussion instrument 200 includes a pedal 210, a connecting rod 220 and a pedal hammer 230, and the connecting rod 220 connects the pedal 210 and the pedal hammer 230; the associated musical instrument includes a signal transmitter 310 and a trigger 320.

[0041] Among them, the lower end 1112 is associated with the above-mentioned first pressure sensor 120, that is, when the user steps on the lower end 1112 of the foot button 111, the first pressure sensor 120 can detect the pressure value received by the lower end 1112. In this embodiment, the pressure value received by the lower end 1112 is referred to as the first pressure value; the upper end 1111 is associated with the above-mentioned second pressure sensor 130, that is, when the user steps on the upper end 1111 of the foot button 111, the first pressure sensor 120 can detect the pressure value received by the upper end 1111. In this embodiment, the pressure value received by the upper end 1111 is referred to as the second pressure value.

[0042] The second pressure sensor 130 is electrically connected to the processor 140, and the processor 140 is electrically connected to the speaker 150. The second pressure value can be directly transmitted to the processor 140, and the processor 140 determines the musical sound signal corresponding to the foot-operated button 111 according to the size of the measured second pressure value, and transmits the musical sound signal to the speaker 150, and the speaker 150 outputs the musical sound signal; the difference is that the first pressure sensor 120 cannot directly transmit the first pressure value measured by it to the processor 140, but needs to transmit the first pressure value to the processor 140 through the signal transmitter 310; as mentioned above, the signal transmitter 310 is one of the components of the associated component 300, and the associated component 300 also includes a signal transmitter connected to the upper Regarding the trigger member 320 on the connecting rod 220, when the user steps on the pedal 210, the connecting rod 220 rotates around its own axis driven by the pedal 210, thereby driving the hammer 230 and the trigger member 320 to move simultaneously, thereby driving the trigger member 320 to trigger the signal transmitter 310 to transmit a signal, that is, when the user steps on the above-mentioned lower end portion 1112, the first pressure value measured by the first pressure sensor 120 can only be transmitted to the processor 140 when the user also steps on the pedal 210 and then drives the trigger member 320 to trigger the signal transmitter 310. The processor 140 determines the musical sound signal corresponding to the foot button 111 according to the size of the first pressure value, and finally the musical sound signal is output by the speaker 150.

[0043] In this way, for the combination musical instrument 10 provided by the present invention, the user can step on the lower end 1112 of the foot button 111 with the left foot and step on the pedal 210 of the percussion instrument 200 with the right foot. The speaker 150 will only make a sound when the pedal 210 and the lower end 1112 of the foot button 111 are stepped on. When the pedal 210 is not stepped on, the speaker 150 will not make a sound even if the lower end 1112 of the foot button 111 is stepped on, which helps to overcome the difficulty of coordinating the movements of people's left and right feet and greatly reduces the difficulty of a single person playing the percussion instrument 200 and the keyboard instrument 100 at the same time. When the pedal 230 of the combination musical instrument 10 outputs the rhythm by hitting the drum, the speaker 150 outputs the harmony, making it possible for a single person to play music with rhythm and harmony, thereby improving the convenience, richness and fun of the combination musical instrument interpretation.

[0044] In addition, since the second pressure sensor 130 can directly transmit the measured second pressure value to the processor 140, that is, as long as the upper end 1111 of the foot-operated button 111 is pressed, the speaker 150 can make a sound without the need for an additional trigger. Therefore, the keyboard instrument 100 can also be played independently from the percussion instrument 200, thereby broadening the application scenarios of the combination instrument 10 and optimizing the convenience of playing the combination instrument 10.

[0045] In this embodiment, the keyboard instrument 100 is a bass or an electronic piano, and the percussion instrument 200 is a drum set or a jazz drum. Of course, in other embodiments of the present invention, the keyboard instrument 100 can also be other types of musical instruments with keyboards, and the percussion instrument 200 can also be other percussion instruments, which are not limited here.

[0046] In addition, the number of the foot-operated keys 111 of the main keyboard 110 can also be 14 or 21, etc., which is not limited here.

[0047] Of course, in other embodiments of the invention, the second pressure sensor 130 may also be omitted.

[0048] In one embodiment, the associated component 300 also includes a vibration switch 340, and the trigger member 320 is a pendulum connected to the connecting rod 220. The signal transmitter 310 is electrically connected to the processor 140 through the vibration switch 340 and is in a normally open state; specifically, when the user steps on the pedal 210, the pedal 210 drives the connecting rod 220 to rotate through a chain (not shown), so that the pendulum connected to the connecting rod 220 also rotates around the central axis of the connecting rod 220. During the rotation, the pendulum causes the vibration switch 340 to vibrate, so that the vibration switch 340 is closed to connect the electrical path between the signal transmitter 310 and the processor 140, and then the measured first pressure value is transmitted to the processor 140.

[0049] In one embodiment, the associated component 300 further includes a flexible circuit board 330, on which the vibration switch 340 and the signal transmitter 310 are both arranged. When the pedal 210 and at least one lower end 1112 are stepped on, the pendulum driven by the connecting rod 220 can strike the flexible circuit board 330, thereby causing the vibration switch 340 to vibrate, and then connecting the circuit between the signal transmitter 310 and the processor 140. Here, the use of the flexible circuit board 330 can well transmit the amplitude, and will not cause excessive contact with the pendulum to cause damage, etc.; moreover, the use of the flexible circuit board 330 can ensure that the connection between the vibration switch 340, the signal transmitter 310 and the processor 140 is stable and reliable while closing the vibration switch 340, thereby improving the reliability of the combined musical instrument 10 and extending its service life.

[0050] Of course, in other embodiments of the present invention, the flexible circuit board 330 may also be replaced by other components that can achieve the above technical effects, and this is not the only limitation here.

[0051] Of course, in other embodiments of the present invention, the trigger member 320 may also be other types of structures or electrical components, and the trigger member 320 may also be arranged under the pedal 210 instead of on the connecting rod 220, which is not the only limitation here; but it can be understood that arranging the pendulum on the connecting rod 220 can facilitate the overall arrangement and installation of the combined musical instrument 10.

[0052] In one embodiment, the keyboard musical instrument 100 further includes a tone conversion button 170, and the tone conversion button 170 includes a plurality of gears, and the key corresponding to the plurality of foot-operated keys 111 can be adjusted by switching the gears. That is, by switching the gears of the tone conversion button 170, the key of the musical sound corresponding to each foot-operated key 111 can be changed. The tone conversion button 170 can be in the form of a key, a pedal 210, or a rotary button, etc., which is not limited here.

[0053] In the present embodiment, the key conversion button 170 is used to switch the key (first key) of the playing, such as C key and D key. With the change of the key, the corresponding musical sound of the corresponding multiple foot-operated buttons 111 also changes accordingly, so the key can be adjusted under the premise of keeping the playing method unchanged, which greatly reduces the complexity of the performance. In other words, by setting the key conversion button 170, it is possible to realize the free switching of multiple keys (such as 12 keys) under the condition that the interval relationship is fixed. For the performer, only a set of fixed playing methods need to be learned to freely realize the free switching of different keys.

[0054] Of course, in other embodiments of the present invention, the tone conversion button 170 may also be omitted, and this is not a sole limitation herein.

[0055] In one embodiment, each foot-operated button 111 corresponds to a plurality of pitches, that is, each upper end 1111 and each lower end 1112 correspond to a plurality of pitches, and the corresponding pitches of the upper end 1111 and the lower end 1112 included in the same foot-operated button 111 correspond to the same pitches. For example, the upper end 1111 and the lower end 1112 of each foot-operated button 111 can correspond to three pitches, and the pitches are changed by force change, that is, each pitch is set to correspond to a different force range, for example, the pronunciations corresponding to the three force ranges are respectively the root note, the third note and the fifth note, and the corresponding pitch is determined by determining the pressure range of the foot-operated force, thereby determining the emitted musical sound. In this way, the performer can play different musical sounds when stepping on the same foot-operated button 111 by controlling the force of playing, which is conducive to further simplifying the complexity of playing.

[0056] In one embodiment, the keyboard instrument 100 also includes a memory 160, which is electrically connected to the processor 140 and is used to store key identifiers corresponding to each foot button 111, the correspondence between the first pressure value and the musical sound, the correspondence between the second pressure value and the musical sound, and the correspondence between the gear position of the tone conversion button 170 and the key.

[0057] Specifically, different pressure values ​​are preset to correspond to different musical sounds, and the corresponding correspondence is stored in the memory 160. The processor 140 can determine the corresponding musical sound signal according to the received pressure value and the corresponding key identifier, combined with the corresponding relationship in the memory 160, and transmit the musical sound signal to the speaker 150. The musical sound signal exists in the form of an electronic signal. After receiving the musical sound signal, the speaker 150 converts the musical sound signal into a sound signal for output. Therefore, the performer can make the speaker 150 emit different sound levels by controlling the pressure.

[0058] It should be noted that each key identifier is used to uniquely identify a foot key 111 , and different foot keys 111 correspond to different pitches, so it is necessary to determine the corresponding musical sound signal based on both the pressure value and the key identifier.

[0059] like Figure 2 The present invention further provides an electronic music processing method, which is applied to a combined musical instrument 10, which includes a keyboard instrument 100, a percussion instrument 200 and an associated component 300. The keyboard instrument 100 includes a main keyboard 110, a first pressure sensor 120, a processor 140 and a speaker 150, the main keyboard 110 includes seven foot-operated buttons 111; the percussion instrument 200 includes a pedal 210, a connecting rod 220 and a hammer 230; and the associated instrument includes a signal transmitter 310 and a trigger 320.

[0061] Wherein, different first pressure value ranges correspond to different sound levels;

[0062] Step S200 , obtaining the key currently indicated by the tone conversion button 170 , and obtaining the key identifier corresponding to the foot-operated key 111 .

[0063] The tone conversion button 170 is used to switch different tones. Under different tones, the music sounds corresponding to the foot-operated button 111 are different.

[0064] In step S300 , the circuit between the signal transmitter 310 and the processor 140 is connected by stepping on the pedal 210 .

[0065] After the electrical path between the signal transmitter 310 and the processor 140 is connected, the signal transmitter 310 is used to transmit the first pressure value to the processor 140 .

[0066] Step S400, determining and outputting corresponding musical sound according to the key, the first pressure value and the key mark.

[0067] After the keynote, the first pressure value and the key mark are determined, the corresponding musical sound can be determined and then output.

[0068] In this embodiment, step S300 includes: stepping on the pedal 210 to rotate the connecting rod 220, thereby driving the trigger member 320 to trigger the signal transmitter 310 and the processor 140 to be electrically connected.

[0069] In one embodiment, the trigger 320 is a pendulum, the associated assembly 300 further includes a flexible circuit board 330 and a vibration switch 340, the signal transmitter 310 is electrically connected to the processor 140 via the vibration switch 340, and the signal transmitter 310 and the vibration switch 340 are disposed on the flexible circuit board 330.
