Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic view illustrating a key module 100 for a percussive melodic instrument according to an embodiment of the present invention. As shown in fig. 1, the key module 100 may include keys 101, key insertion openings 102, and vibration damping members 103. The key 101 may be used to receive a strike or depression from a user and generate vibration energy based on the strike or depression. The striking or depression by the user may be generated by striking the key 101 with a striking member such as a drumstick or the like, or may be generated by striking the key 101 with a hand.

The above-described key insertion opening 102 may be disposed in an upper portion of the key 101 and may be used for mounting a sensing unit. As shown in fig. 1, the key insertion opening 102 may be a plane reserved on the key 101. For connecting the sensing unit, an adhesive substance such as a hook and loop fastener, a double-sided tape, or the like, or an adhesive coating or the like is applied to a side of the plane (the upper surface of the plane shown in fig. 1) remote from the key 101, so as to connect the sensing unit such as a flexible pressure sensor (bending pressure sensor, "FSR") to the key 101. The arrangement mode of the embedding opening 102 can prevent the key 101 from influencing the striking or pressing of the user on the key 101 after the induction unit is installed, so that the influence can ensure the playing hand feeling of the user.

In one embodiment, the vibration reduction element 103 described above may be connected to or in contact with the key 101 at the bottom of the key 101 and serve to attenuate vibration energy generated by the key 101 so as to achieve vibration reduction. The damping element 103 may comprise a damping slide, a sponge, a spring or an air cushion, depending on the application. Wherein the sponge can comprise zero-pressure cotton, slow-rebound cotton or EVA cotton. From the type of spring, it may comprise a stainless steel spring or a plastic spring; from the material of the spring, it may include a compression spring, a damper spring, or a disc spring. In particular, the spring may comprise a stainless steel shock absorbing spring or a plastic compression spring.

In addition, when the damping element 103 is a sponge or an air cushion, the damping element 103 may be a sponge or an air cushion having, for example, a rectangular parallelepiped or a square parallelepiped shape; when the damping element 103 is a spring, the damping element 103 may be a cylindrical spring, for example. It is understood that the damping element 103 may have other shapes depending on the application. For example, it may be a cylindrical, truncated cone or prism-shaped sponge or air cushion, or a truncated cone-shaped spring, etc., which are not listed here.

The way in which the damping element 103 is in contact with the bottom of the key 101 may simplify the process of connection between the damping element 103 and the key 101. To facilitate the replacement of the damping element 103, in one embodiment the damping element 103 may be detachably connected to the key 101. For example, when the vibration reduction element 103 is the above-described sponge or air cushion, it may be attached to the key 101 by means of a hook and loop fastener. When the damping element 103 is a spring as described above, a connection ring (closed ring) may be provided at the bottom of the key 101, into which one end of the spring may be inserted to be detachably connected thereto. When the damping element 103 is a damped slide rail as described above, a snap ring may be provided at the bottom of the key 101 and a hole or attachment ring may be provided at the damping end of the damped slide rail, which hole or attachment ring may snap into the snap ring at the bottom of the key 101 to snap into engagement therewith.

In order to prevent easy disengagement between the damping element 103 and the key 101, in another embodiment, the damping element 103 may also be fixedly connected to the key 101. For example, when the vibration damping element 103 is the above-described sponge or air cushion, it may be attached to the key 101 by a double-sided tape or the like. When the vibration damping member 103 is the spring as described above, it may be connected to the key 101 by riveting, screwing, welding, or the like. When the damping element 103 is a damped slide rail as described above, the bottom of the key 101 may be provided with an attachment ring, and the damping end of the damped slide rail may be provided with a hole or attachment ring which snaps into fixed connection with the attachment ring at the bottom of the key 101.

In order to reduce the cost of the key module 100, in one embodiment, the length and/or width of the vibration reduction element 103 may be made smaller than the length and/or width of the key 101 so that the area of the vibration reduction element 103 is smaller than the key 101. Such a vibration damping member 103 having a small area can be disposed at an intermediate position of the bottom of the key 101, so that vibration energy generated from the key 101 can be attenuated to a large extent and the cost of the key module 100 can be reduced. The damping element 103 may also be arranged on the side of the bottom of the key 101, depending on the application scenario.

In order to achieve a better vibration damping effect, in another embodiment, the vibration damping element 103 may also be as long as the key 101 and as wide as possible so that the vibration damping element 103 has an equal area as the key 101. The vibration reduction element 103 with the same area as the key 101 can be arranged in alignment with the key 101, so that vibration energy generated by the key 101 can be attenuated at each position of the bottom of the key 101, and a better vibration reduction effect is achieved.

As can be seen from the above description, the vibration damping element 103 in the present embodiment can damp the vibration energy generated by the key 101 at the bottom of the key 101, so that it is possible to prevent the keyboard using the key module 100 or other keys on the percussive melody instrument from generating the audio signal by mistake due to the vibration of the key 101, and thus, the playing effect can be ensured.

It is to be understood that the above-described key module 100 structure is only exemplary and not restrictive, and those skilled in the art can modify it as necessary to meet the requirements of different application scenarios. For example, the insertion opening 102 may be a slot into which the sensing unit is inserted to be connected to the key 101. In order to prevent the sensing unit from being removed from the socket, the width of the notch may be smaller than that of the sensing unit mounted therein. In addition, the slot may be connected to the key 101 by means of double-sided tape, riveting, screwing, welding, or the like. It can be understood that the sensing unit can be conveniently disassembled and replaced by installing the sensing unit in the slot.

In the above embodiment, only the case where one embedded port is included is described, and it will be understood by those skilled in the art that a plurality of sensing units may be required in the key module 100 depending on the application scenario. Therefore, a plurality of key insertion openings, for example, 2 or 3, need to be arranged in the key module 100, the plurality of insertion openings may be arranged in a uniform or non-uniform manner on the upper surface of the key 101, and the plurality of insertion openings may be entirely provided as a plane or a slot, or partially provided as a plane, and the other portion provided as a slot in the above manner.

The case where the vibration attenuating element 103 is disposed on the bottom of the key 101 and the insertion opening 102 is disposed on the upper portion of the key 101 was described above in connection with the embodiment shown in fig. 1. It will be appreciated by a person skilled in the art that the sensing unit may also be mounted at a different location of the key 101, for example also in the middle or lower part of the key 101, and thus the key insertion opening 102 may also be mounted in the middle or lower part of the key 101. .

A case will be described below, with reference to fig. 2, where the vibration attenuating element 203 is disposed on the bottom of the key 201, and the insertion opening 202 is disposed on the lower portion of the key 201 (i.e., the vibration attenuating element 203 and the insertion opening 202 are disposed on the same side of the key 201). The same parts of the embodiment shown in fig. 2 as those of the above-described embodiment can be referred to the foregoing description, such as the components selected for the vibration damping member 203, the arrangement, the connection with the key 201, and the like, and will not be described in detail herein. Reference numeral 200 in fig. 2 denotes a key module.

In this embodiment, the insertion opening 202 may be a slot disposed on one side of the damping element 203, and a sensing unit such as a piezo ceramic sensor, a mems acceleration sensor, a mems gyroscope, a mems pressure sensor, or a mems vibration sensor may be inserted into the slot. The structure of the slot, the connection relationship with the key 201, and the like can be referred to the description of the foregoing embodiments, and will not be described in detail here.

In order to save space in the lower part of the key 201 so that other components can be mounted or arranged, the insertion opening 202 in the present embodiment may also be a reserved plane as shown in fig. 1. The structure of the plane and the connection relationship with the key 201 can also be as described in the above embodiments, and will not be described in detail here. When the insertion port 202 in the present embodiment is plural, it may be arranged in a symmetrical or asymmetrical manner on both sides of the damping element 203 or in a uniform or non-uniform manner around the damping element 203, and may also be entirely a slot or a plane as described in the previous embodiments, or partially a slot and partially a plane.

As can be seen from the description of the foregoing embodiments, the above-described one or more insertion ports may also be disposed in the middle of the key 201. In this case, the insertion opening may be one or more prepared openings so that one or more sensing units such as pressure sensors are inserted into the prepared openings to be connected to the key 201.

The case where the vibration attenuating element is disposed on the bottom of the key and attenuates the vibration energy generated therefrom only at the bottom of the key has been described above in connection with the various embodiments. In order to make the vibration reduction element at the bottom of the key attenuate the vibration energy generated by the key from multiple directions, thereby achieving better vibration reduction effect, the vibration reduction element can be arranged in the structure shown in fig. 3. A case where the vibration attenuating element 303 is disposed at the bottom of the key 301 but can attenuate vibration energy generated from the key 301 simultaneously at the bottom and the side walls of the key 301 will be described below with reference to fig. 3.

In the present embodiment, the insertion opening 302 may be a reserved plane or a slot disposed in an upper portion of the key 301, which may be connected to the key 301 in the manner described in the foregoing embodiments, and the number thereof may also be one or more. For simplicity of description, only one embedding port 302 is exemplarily shown in fig. 3, and the embedding port 302 is a reserved plane.

As can be seen from fig. 3, the damping element 303 in this embodiment may comprise a sponge or an air cushion with a recess. The vibration attenuating element 303 may be arranged at the bottom of the key 301, and at least the key 301 is located in a recess of the vibration attenuating element 303, so that the vibration attenuating element 303 attenuates the vibrational energy it generates at least at the bottom of the key 301. In addition, the bottom and side walls of the sponge or air cushion may be connected to or in contact with the key 301 with reference to the previous embodiments, which will not be described in detail herein.

As can be seen from fig. 3, the damping element 303 can be of a channel-shaped configuration. The height of the side walls on both sides of the groove-shaped vibration attenuating element 303 may be smaller than the height of the key 301, and the shape and size of the recessed portion thereof may be adapted to the shape and size of the lower portion of the key 301, so that the bottom and both side walls of the vibration attenuating element 303 may be brought into contact with the lower portion of the key 301, and vibration energy generated therefrom may be attenuated at the bottom and both sides of the key 301. In addition, since the height of the side walls on both sides of the groove-shaped vibration damping member 303 is smaller than that of the key 301, it is possible to reduce the cost of the key module 300 while satisfying the vibration damping effect.

Further, the thickness and height of the side walls on both sides of the above-described groove-shaped vibration damping element 303 may be equal, so that the vibration energy generated therefrom can be uniformly attenuated on both sides of the key 301. In addition, the height of the side walls on the two sides of the groove-shaped vibration reduction element 303 can also be equal to that of the key 301, so that vibration energy generated by the key 301 can be attenuated at each position on the two sides of the key 301, and a better vibration reduction effect is achieved.

The damping element may also be a box structure with four side walls, similar to one open end, for a greater degree of damping. Similarly to the above embodiment, the height of the four side walls of the box-shaped vibration damping element may also be smaller than the height of the key 301, and the shape and size of the recessed portion may also be adapted to the shape and size of the lower portion of the key 301, so that the vibration energy generated by the key 301 may be attenuated at the bottom and around the key 301, and a better vibration damping effect may be achieved. In addition, since the heights of the four side walls of the box-like vibration damping member are smaller than the height of the key 301, it is possible to reduce the cost of the key module 300 while satisfying the vibration damping effect.

Further, the thicknesses and heights of the four side walls of the vibration reduction element 303 may also be equal, so that the vibration energy generated from the key 301 can be uniformly attenuated around the key. In addition, in order to achieve better vibration damping effect, the heights of the four side walls of the box-shaped vibration damping element 303 can also be equal to the height of the key 301, so that vibration energy generated by the key 301 can be attenuated at various positions around the key 301, and further better vibration damping effect can be achieved. As is apparent from the above description, the vibration damping member 303 of the present embodiment can damp vibration energy generated from the key 301 in more directions (bottom and side walls), and thus can achieve a better vibration damping effect.

The case where the vibration attenuating element is provided on the bottom of the key but does not surround the key on the side and surrounds the key on both the bottom and side of the key has been described above in connection with the embodiments. It will be understood that, in addition to the shapes and structures listed above, the vibration damping element may be provided in other shapes and structures matching the shape and structure of the key according to the application, and the like, which are not listed here.

The case where the vibration damping member is disposed on the bottom of the key has been described above in connection with the various embodiments. It will be appreciated by those skilled in the art that the vibration damping element may also be arranged on the side of the key for connection to a key adjacent thereto for vibration damping, depending on the application, for example, the connection of the other end of the vibration damping element to the key. A case where the vibration damping member 403 is disposed on the side of the key 401 will be described below with reference to fig. 4.

As is apparent from the description of the foregoing embodiment, the insertion opening 402 may be disposed above, in the middle of, or below the key 401, and may be a previously-described reserved plane, a socket, a slot, or the like. In addition, the insertion port 402 may also be arranged and connected to the key 401 in the manner described in the foregoing embodiment. Further, the number of the insertion openings may be one or more, and when the insertion openings are plural, they may be all planar, slots or sockets, or partially planar, and partially slots, or partially slots, and partially slots. For simplicity of description, fig. 4 shows only an example in which the insertion opening 402 is a slot and is disposed in the lower portion of the key 401.

As can be seen from fig. 4, vibration damping elements 403 may be attached to or in contact with key 401 at the sides of key 401 and serve to attenuate vibration energy generated by key 401 to achieve vibration damping. Depending on the application, the damping element 403 may comprise a spring or a cable. From the type of spring, it may comprise a stainless steel spring or a plastic spring; from the material of the spring, it may include an extension spring or a damper spring. In particular, the spring may comprise a stainless steel extension spring. The rope may comprise a nylon rope or a manila rope or the like.

The manner in which the dampening element 403 contacts the side of the key 401 may simplify the attachment process between the dampening element 403 and the key 401. To facilitate replacement of dampening element 403, dampening element 403 may be removably attached to key 401 in one embodiment. For example, when the vibration damping member 403 is the spring described above, a connection ring may be provided on the side of the key 401, and one end of the spring may be inserted into the connection ring to be detachably connected thereto. When the vibration damping member 403 is the above-described rope, a connection ring may also be provided on the side of the key 401, and one end of the rope is tied to the connection ring by a cord lock that is easily released, so that detachable connection of the rope to the key 401 can be achieved.

In order to prevent easy disengagement between the dampening element 403 and the key 401, in another embodiment the dampening element 403 may also be fixedly connected to the key 401. For example, when the vibration damping member 403 is the spring described above, it may be connected to the key 401 by riveting, screwing, welding, or the like. When the damping element 403 is a cord as described above, it may be tied to the attachment ring of the key 401 by a non-releasable cord fastener.

As shown in fig. 4, the above-described vibration damping element 403 may be disposed at an intermediate position on the side of the key 401 (the position of connection of the vibration damping element 403 and the key 401 is located at an intermediate position on the side of the key 401), so that vibration energy generated therefrom may be attenuated to a large extent at the side of the key 401. When the vibration attenuating element 403 is attached to the key 401, it may form an angle of, for example, 90 ° or 85 ° with the side surface of the key 401 (the side surface of the key 401 above the attachment position of the vibration attenuating element 403 to the key 401), so that vibration energy generated from the key 401 can be attenuated to a large extent.

It is to be understood that the arrangement positions of the vibration reduction elements 403 and the angles with the side surfaces of the key 401 are illustrative and not restrictive, and may be changed as required by those skilled in the art. For example, it is also possible to have the vibration damping member 403 attached to the upper or lower portion of the side surface of the key 401 (i.e., the attachment position of the vibration damping member 403 and the key 401 is located on the upper or lower portion of the side surface of the key 401), and the angle with the side surface of the key 401 may be 80 ° or 75 °, or the like.

As can be seen from the above description, the vibration damping elements 403 in the key module 400 can damp the vibration energy generated by the keys 401 at the side surfaces thereof, so that the keyboard using the key module 400 or other keys on the percussive melody instrument can be prevented from generating audio signals by mistake due to the influence of the vibration of the keys 401, and the playing effect can be ensured.

As can be understood from the description of the foregoing embodiments, a sensing unit may be installed in the key insertion opening for sensing a strike or depression of the key or the functional area disposed corresponding to the key. Taking the aforementioned key module 500 shown in fig. 2 as an example, the key module 500 may further include a sensing unit 505 mounted in the recessed opening 502 and configured to sense a strike or depression of the key 501 or a functional area disposed corresponding to the key 501, and to generate a sensing signal based on the sensed strike or depression. Wherein a circuit for outputting a variation parameter according to the striking or pressing may be arranged in the function area. Depending on the application, the functional area may be a trigger area where a capacitive circuit is disposed or a magnetic induction area where a magnetic induction circuit is disposed. Reference numeral 504 in fig. 5 denotes a damping element.

As can be seen from fig. 5, the sensing unit 505 is inserted in the slot of the key module 500 and has a width larger than that of the notch 503, so that it can be prevented from falling out of the slot. As can be seen from the foregoing description of the embodiments, the sensing unit 505 can be a piezoelectric ceramic sensor, a mems acceleration sensor, a mems gyroscope, a mems pressure sensor, or a mems vibration sensor.

It is to be understood that the corresponding sensing units may be disposed in the key modules as described with respect to the other embodiments. For example, with the key module shown in fig. 1 and 3, a sensing unit such as a flexible pressure sensor may be attached through a side thereof remote from the key. For a key module in which a key insertion opening is arranged in the middle of the key, a sensing unit such as a pressure sensor may be inserted into a reserved socket.

For a key module in which a plurality of key insertion openings are arranged, a plurality of sensing units may be arranged correspondingly. The plurality of induction units can generate a plurality of induction signals, so that the percussion melody musical instrument can obtain more accurate musical tone signals according to the plurality of induction signals, and the playing accuracy can be further ensured.

As can be seen from the above description, the key module 500 can sense the striking or pressing of the key 501 or the functional area disposed corresponding to the key 501 through the disposed sensing unit 505 and generate a sensing signal, so that the struck melody musical instrument using the key module 500 can acquire a corresponding tone signal according to the sensing signal, and can perform a performance.

Fig. 6 is a schematic diagram showing a keyboard 600 for percussion performance according to an embodiment of the present invention. In the present embodiment, the keyboard 600 may include a plurality of key modules (such as the key modules shown in fig. 1, 2, 3, and 5) in which vibration reduction elements are arranged at the bottoms of keys, and a plurality of support plates. The number of key modules and the number of support plates may be set as desired, and may be 2 or 3, for example. For simplicity of description, fig. 6 shows, by way of example only, a case including 2 key modules shown in fig. 2 and 2 support plates.

In one embodiment, each support plate may be disposed below a corresponding key module and serves to support and mount the key module. As shown in fig. 6, the support plate 604 may be disposed below a first key module composed of keys 601, insertion openings 602, and vibration damping members 603, and the support plate 608 may be disposed below a second key module composed of keys 605, insertion openings 606, and vibration damping members 607. The vibration damping elements in each key module may be connected to or in contact with a support plate that supports and mounts the key module, and serve to damp vibration energy conducted from the keys to the support plate so as to achieve vibration damping. For example, with the first key module described above, the vibration reduction element 603 may be connected to or in contact with the support plate 604; while for the second key module described above, the vibration attenuating element 607 may be connected or in contact with the supporting plate 608.

The manner in which the vibration reduction elements are in contact with the support plate that supports and mounts the key module can simplify the attachment process between the key module and the support plate. In order to facilitate the replacement of the key module, in one embodiment, the vibration reduction element and the support plate may be detachably connected. Taking the first key module as an example, when the damping element 603 is the aforementioned sponge or air cushion, it may be adhered to the supporting plate 604 by a hook and loop fastener or the like. When the damping element 603 is a spring as described above, a coupling ring can be provided on the support plate 604, into which one end of the spring can be passed and detachably connected. When the damping element 603 is the damping slide rail, a clamping piece may be disposed at the bottom end of the damping slide rail and on the upper surface of the supporting plate 604, respectively, and the clamping between the damping slide rail and the supporting plate 604 is realized through the two clamping pieces.

In order to prevent an easy disengagement between the damping element and the support plate, the damping element may also be fixedly connected with the support plate in another embodiment. Also taking the first key module as an example, when the vibration damping element 603 is the aforementioned sponge or air cushion, it may be connected to the support plate 604 by a double-sided tape or the like. When the damping element 603 is the aforementioned spring, it may be connected to the support plate 604 by riveting, screwing, welding, or the like. When the vibration damping element 603 is the damping slide rail, a connecting piece may be disposed at the bottom end of the damping slide rail, and the connecting piece may be riveted, screwed or welded to the supporting plate 604, so as to fixedly connect the damping slide rail and the supporting plate 604.

The plurality of support plates in the keyboard 600 may be separated, contacted or connected according to different application scenarios. For example, the support plate 604 and the support plate 608 may be separated, contacted, or connected. In addition, the support plate 604 and the support plate 608 may be detachably connected to each other, so that the separation of the first key module and the second key module is achieved by separating the support plate 604 and the support plate 608, and the replacement of the first key module or the second key module is achieved. Further, the support plate 604 and the support plate 608 may be fixedly connected to each other, so that the support plate can be prevented from being loosened.

In combination with the foregoing description of the key module, those skilled in the art can understand that the vibration-damping element in the present embodiment can damp the vibration energy generated by the keys at the bottom of the keys, so as to prevent other keys on the keyboard 600 from generating audio signals by mistake due to the vibration of the keys, and further ensure the playing effect. Still taking the first key module as an example, since the vibration attenuating element 603 thereof can attenuate the vibration energy generated by it at the bottom of the key 601, it is possible to prevent the key 605 from erroneously generating an audio signal due to the vibration of the key 601.

Fig. 7 is a schematic diagram showing a keyboard 700 for percussion performance according to another embodiment of the present invention. In the present embodiment, the keyboard 700 may include a plurality of key modules (such as the key module shown in fig. 4) in which vibration reduction elements are arranged on the side of keys, and a plurality of support plates. The number of key modules and the number of support plates may be set as desired, and may be, for example, 2, 3, or 4, or the like. For simplicity of description, fig. 7 shows, by way of example only, a case including 2 key modules and 2 support plates.

In one embodiment, each support plate may be disposed below a corresponding key module and serves to support and mount the key module. As shown in fig. 7, support plate 704 is disposed below a third key module composed of keys 701, insertion openings 702, and vibration damping elements 703, while support plate 707 is disposed below a fourth key module composed of keys 705, insertion openings 706.

Similar to the above embodiments, a plurality of supporting plates, such as the supporting plate 704 and the supporting plate 707, may be separated, contacted or connected, and will not be described in detail herein. In addition, each support plate may be detachably attached or fixedly attached to the corresponding key. For example, support plate 704 may be detachably or fixedly connected to key 701, and support plate 707 may be detachably or fixedly connected to key 705.

In one embodiment, the vibration reduction element in each key module may be connected to or in contact with a key adjacent to the key in the key module, and serves to attenuate vibration energy conducted by the key to the key adjacent to the key, so as to achieve vibration reduction. For example, the dampening elements 703 in the third key module may be connected to or in contact with the key 705. The manner in which the dampening elements are in contact with the keys may simplify the connection process between the key modules.

To facilitate replacement of the key module, in one embodiment, the vibration reduction member is detachably connected to the keys adjacent to the keys in the key module. Taking the third key module as an example, when the vibration damping element 703 is the aforementioned spring, a coupling ring may be provided on the side of the key 705, into which one end of the spring may be inserted to be detachably coupled thereto. When the damping element 703 is the aforementioned rope, a connection ring may also be provided on the side of the key 705, and one end of the rope is tied to the connection ring by a cord lock that is easily released, so that the detachable connection of the rope to the key 705 can be achieved.

To prevent easy disengagement between dampening element 703 and key 705, dampening element 703 may also be fixedly connected to key 705. When the damping element 703 is the aforementioned spring, it may be connected to the key 705 by riveting, screwing, welding, or the like. When the damping element 703 is the aforementioned cord, it may be tied to the attachment ring on the side of the key 705 by a non-releasable cord fastener.

It will be appreciated that the right side of the key 705 of the fourth key module (i.e., the same side as the key 701) may also be arranged with a vibration damping element. When the keyboard 700 includes more key modules, for example, 3, the dampening elements in this fourth key module may be connected to the keys of other key modules (e.g., the key module on the right side of the fourth key module) in the manner shown by dampening elements 703 to achieve dampening.

In combination with the foregoing description of the key module, those skilled in the art can understand that the vibration damping element in the present solution can attenuate the vibration energy generated by the keys at the side of the keys, so as to prevent other keys on the keyboard from generating audio signals by mistake due to the vibration of the keys, and further ensure the playing effect. Still taking the third key module as an example, since the vibration damping element 703 can attenuate the vibration energy generated by the key 701 on the side surface thereof, it is possible to prevent the key 705 from erroneously generating an audio signal due to the vibration of the key 701.

Fig. 8 is a schematic diagram showing a percussion melody musical instrument 800 according to an embodiment of the present invention. In this embodiment, the percussion melody instrument 800 may include one or more of the keyboards and instrument bodies 808 described in the previous embodiments. The instrument body 808 may be disposed below and used to support and secure one or more keyboards. The number of the keyboards can be set according to needs, and for example, the number of the keyboards can be 2 or 3. For simplicity of description, the figure shows only an example case where 1 keypad 810 shown in fig. 7 is included. Reference numeral 806 in fig. 8 is a fitting port.

In one embodiment, the keyboard 810 may be removably attached to the instrument body 808. For example, the supporting plates 804 and 807 of the keyboard 810 may be detachably connected to the instrument body 808, so that the keyboard 810 can be easily replaced. The keyboard 810 may also be fixedly attached to the instrument body 808. For example, the supporting plates 804 and 807 of the keyboard 810 may be fixedly connected to the instrument body 808, so that the keyboard 810 may be prevented from being released.

In conjunction with the description of the keyboard 810, those skilled in the art can understand that the vibration damping element 803 in the present embodiment can damp the vibration energy generated by the key 801, so as to prevent the other keys on the percussive melody instrument 800 from generating audio signals by mistake due to the vibration of the key 801, and thus ensure the playing effect. Taking the key module composed of the key 801, the insertion opening 802 and the vibration reduction element 803 as an example, the sound signal can be prevented from being erroneously generated by the key 805 due to the vibration of the key 801 due to the vibration reduction action of the vibration reduction element 803, and the playing effect of the percussive melody musical instrument 800 can be ensured.
