Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cymbal, and particularly relates to a novel electronic cymbal. BACKGROUND

[0002] The original cymbal is a percussion instrument, usually refers to the cymbal in the jazz drum, and is an indispensable playing tool for every drummer. The traditional cymbal is divided into three types of pure mechanical processing, semi-mechanical and semi-manual, and pure manual processing. Moreover, the traditional cymbal is made of copper-based alloy.

[0003] The cymbal can be further divided into a pedal cymbal, a crash cymbal and a bell cymbal in terms of form. However, the sound production principle of the cymbal is similar. The player strikes the cymbal by using a striking object similar to a drumstick, so that the cymbal produces vibration, further drives the surrounding air vibration to produce a sound that can be heard by human ears.

[0004] For the traditional cymbal, due to the need of its own performance, the sound emitted during performance is loud. The cymbal in a general jazz drum set can emit a sound of 119 decibels at the highest. Therefore, in some specific use environments such as home use, it may cause sound disturbance to the surrounding non-performing personnel. Therefore, with the progress of science and technology and the rise of electronic percussion instruments, an electronic cymbal also appears to replace the traditional cymbal to further adapt to the use in special environments.

[0005] The electronic cymbal first has a flat part similar to the original cymbal as a striking surface, and at least one trigger. When the striking surface of the electronic cymbal is struck, the mechanical vibration of the striking surface is transmitted to the trigger, thereby generating an electrical signal output associated with the mechanical vibration. The electrical signal is then received by the sound source of the electronic drum and converted into a musical electrical signal according to a predetermined program. The musical electrical signal is converted into a sound that can be perceived by human ears through a specific sound amplification device such as a sound box or a headphone. Therefore, the size of the sound finally emitted by the electronic percussion instrument is determined by the sound amplification device. If the user wants to reduce the volume, he only needs to control the sound amplification device. In this way, the problem described above is solved.

[0006] However, the biggest difference between the existing electronic cymbal and the original cymbal is the material used. The electronic cymbal is generally made of non-metallic materials. Therefore, the electronic cymbal will not produce a musical sound when it is hit. Furthermore, when hitting, the user's hitting feeling is completely different from that of the traditional cymbal, that is, the electronic cymbal cannot give the user a feedback feeling similar to the original cymbal metal material in use. The playing feeling of the instrument is the most important factor to judge the quality of the instrument besides the sound, so the existing electronic cymbal is difficult to achieve this. Therefore, it is urgent to develop an electronic cymbal to solve the problem of poor hitting feeling of the existing electronic cymbal. SUMMARY

[0007] The purpose of the present application is to provide a new type of electronic cymbal.

[0008] To achieve the above-mentioned purpose of the application, the present application provides a new type of electronic cymbal, comprising: a metal structure for hitting, an electronic trigger for sensing the hitting vibration of the metal structure and converting it into an electrical signal;

[0009] The opposite sides of the metal structure are a hitting surface and a non-hitting surface, respectively, wherein part or all of the non-hitting surface is provided with a sound-absorbing layer;

[0010] The metal structure is further provided with a weight-reducing structure.

[0011] According to one aspect of the present application, the metal structure comprises: a cymbal cap portion and a cymbal surface portion connected to the cymbal cap portion;

[0012] The thickness of each position of the cymbal surface portion is uniform; or,

[0013] The thickness of the cymbal surface portion gradually decreases in the direction from the cymbal cap portion to the edge of the cymbal surface portion.

[0014] According to one aspect of the present application, the weight-reducing structure is a hole provided on the metal structure, and the hole has an opening on the hitting surface of the metal structure;

[0015] The opening diameter of the hole on the hitting surface is less than or equal to 6mm.

[0016] According to one aspect of the present application, the hole is a through hole penetrating through the metal structure, and the opening diameter of the hole on the non-hitting surface is greater than or equal to 1.5mm.

[0017] According to one aspect of the present application, the metal structure is made of steel, aluminum, copper or alloy.

[0018] According to an aspect of the present application, the metal structure is a structural body of the electronic cymbal; or, the metal structure is a partial structure of the electronic cymbal.

[0019] According to an aspect of the present application, if the metal structure is a structural body of the electronic cymbal, the metal structure is a central symmetric structure.

[0020] According to an aspect of the present application, if the metal structure is a partial structure of the electronic cymbal, the electronic cymbal further comprises a connecting support part;

[0021] The metal structure and the connecting support part are fixedly connected or detachably connected with each other.

[0022] The connecting support part is made of a non-metal material.

[0023] According to an aspect of the present application, the sound-absorbing layer is made of a flexible material, and the sound-absorbing layer has an elongation at break ≥ 150% and a tensile strength ≥ 4 MPa.

[0024] According to an aspect of the present application, the sound-absorbing layer is made of polyurea.

[0025] The connecting support part is made of plastic or rubber.

[0026] According to an aspect of the present application, the electronic cymbal of the present application effectively ensures the knocking feeling of a user during use by using a metal structure as a knocking part. In addition, by applying a sound-absorbing layer on a non-knocking surface, the vibration of the metal structure is further suppressed while the knocking feeling of the metal structure is ensured, and the volume generated by the metal structure when being knocked is reduced.

[0027] According to an aspect of the present application, by providing a weight-reducing structure on the metal structure, the overall weight of the metal structure is further reduced, which is beneficial to reducing the vibration and sound volume of the metal structure when being knocked. In particular, in combination with the further suppression of vibration by the sound-absorbing layer, the vibration of the present application when being knocked is lower, the sound volume is smaller, and the knocking feeling is better.

[0028] According to an aspect of the present application, by setting the opening size of the hole to be greater than or equal to 1.5 mm and less than or equal to 6 mm, it is ensured that the weight-reducing structure is not too large to affect the knocking feeling due to the small area of the knocking surface, and the sound-absorbing effect is not poor due to the small weight-reducing structure, thereby effectively ensuring the knocking feeling of the metal structure while effectively suppressing the structural vibration of the metal structure.

[0029] According to one aspect of the present invention, the electronic cymbal can be made of metal materials of different types to form the metal structure. For metal structures of different materials, different sizes of weight-reducing structures can be selected to achieve matching noise reduction effects, making the design and manufacturing of the present invention more flexible and diverse.

[0030] According to one aspect of the present invention, by employing a split-structure support for the electronic cymbal, when the metal structure is struck, since the connecting support and the metal structure are made of different materials, the vibration of the metal structure is effectively reduced on the connecting support, thereby further suppressing the striking volume.

[0031] According to one aspect of the present invention, costs can be reduced by partially using metallic materials. Furthermore, since composite materials are easy to mold, it is relatively convenient to install sensors and other related components.

[0032] According to one aspect of the present invention, by applying a sound-absorbing layer only to the non-impacting surface of the metal structure, it is not necessary to spray the impacting surface. This maintains the metallic luster of the impacting surface, thus achieving an aesthetic effect. Attached Figure Description

[0044] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the accompanying drawings needed to be used in the embodiments will be briefly introduced. Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without any creative effort based on these drawings.

[0045] In the description of the embodiments of the present application, the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" express the orientation or positional relationship shown in the relevant drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0046] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments, which cannot be exhaustively described here, but the embodiments of the present application are not limited to the following embodiments.

[0047] In conjunction with Figure 1 , Figure 2 , Figure 3 As shown in the drawings, according to an embodiment of the present application, a new type of electronic cymbal comprises a metal structure 1 for striking, and an electronic trigger for sensing the striking vibration of the metal structure 1 and converting it into an electrical signal. In this embodiment, the electronic trigger can be made of piezoelectric ceramic, or other forms of structure that can sense the vibration generated by the metal structure when it is struck and convert the vibration into a corresponding electrical signal. In this embodiment, the metal structure 1 is in the form of a plate as a whole, and the two opposite sides in the thickness direction are the striking surface and the non-striking surface, respectively, wherein part or all of the non-striking surface is provided with a sound-absorbing layer 2. In this embodiment, a weight-reducing structure 3 is also provided on the metal structure 1.

[0048] Through the above arrangement, the electronic gong of the present application effectively ensures the knocking feeling of the user during use by adopting a metal structure as the knocking part. In addition, by applying a sound-absorbing layer on the non-knocking surface, the vibration of the metal structure is further inhibited, and the volume of the sound produced by the metal structure when being struck is reduced.

[0049] Through the above arrangement, by arranging the weight-reducing structure on the metal structure, the overall weight of the metal structure is further reduced, which is beneficial to reducing the vibration and sound volume of the metal structure when being struck. In particular, in combination with the further inhibiting effect of the sound-absorbing layer on the vibration, the metal structure of the present application has lower vibration and smaller sound volume when being struck, while maintaining a better knocking feeling.

[0050] In combination with Figure 1 , Figure 2 , Figure 3 It is shown that, according to an embodiment of the present application, the metal structure 1 comprises a gong cap part 11 and a gong surface part 12 connected to the gong cap part 11. In this embodiment, the sound-absorbing layer 2 can be attached to one side of the gong cap part 11 and the gong surface part 12, or only to one side of the gong surface part 12, which can be arranged as needed. Similarly, the weight-reducing structure 3 can be arranged on both the gong cap part 11 and the gong surface part 12, or only on the gong surface part 12.

[0051] In this embodiment, the thickness of the gong surface part 12 at each position is consistent. Through the above arrangement, by setting the thickness of the gong surface part to be consistent, the processing difficulty of the gong surface part can be effectively reduced. Of course, in another embodiment, the thickness of the gong surface part 12 and the gong cap part 11 can also be consistent, so that a plate material with consistent thickness can be integrally processed and formed, which can further reduce the processing difficulty and production cost, and will not affect the knocking feeling. In addition, since the production difficulty of the metal structure is effectively reduced, the yield of the product is more easily improved.

[0052] According to another embodiment of the present application, the thickness of the gong surface part 12 gradually decreases in the direction from the gong cap part 11 to the edge of the gong surface part 12. In this embodiment, the thickness of the gong surface part is set to be variable, so that it is more similar to the structure of a traditional gong, and can further ensure the feeling of the user when striking.

[0053] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, according to one embodiment of the present application, the weight-reducing structure 3 is a hole arranged on the metal structure 1, and the hole has an opening on the striking surface of the metal structure 1. In this embodiment, the opening diameter of the hole on the striking surface is less than or equal to 6 mm. In this embodiment, the size of the opening on the striking surface is adjusted according to the material of the metal structure, so as to ensure the overall structural strength of the metal structure while reducing the weight of the metal structure.

[0054] Through the above arrangement, by arranging the weight-reducing structure as a hole, the weight of the metal structure itself can be effectively reduced, and the integrity of the overall shape of the metal structure can be more easily ensured. In addition, the hole is easy to process, and the processing precision is easy to control, thereby achieving precise control of the weight of the metal structure and optimizing the weight reduction of the metal structure.

[0055] In this embodiment, the opening diameter of the hole on the striking surface is greater than or equal to 1.5 mm.

[0056] Through the above arrangement, the opening size of the hole is arranged to be greater than or equal to 1.5 mm and less than or equal to 6 mm, which can effectively ensure that the weight-reducing structure is not too large to cause the area of the striking surface to be too small and affect the striking feeling, and also can effectively prevent the problem of poor sound reduction effect caused by the weight-reducing structure being too small, thereby effectively ensuring the striking feeling of the metal structure while effectively suppressing the structural vibration of the metal structure.

[0057] In combination with Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, according to one embodiment of the present application, the hole is a through hole penetrating the metal structure 1, and the opening diameter of the hole on the non-striking surface is greater than or equal to 1.5 mm. In this embodiment, the weight-reducing structure 3 arranged on the metal structure 1 is a through hole, which can be arranged as a straight circular hole with a constant diameter, or as a tapered hole, a stepped hole, a combination of a straight hole and a tapered hole, and the like, and can be arranged as needed.

[0058] In this embodiment, since the weight-reducing structure 3 is a through hole, and the opening of the through hole on the non-striking surface does not affect the striking effect, when a tapered hole or a stepped hole is used, the opening of the through hole on the non-striking surface can be greater than 6 mm while maintaining the structural strength of the striking surface, so as to ensure the striking feeling on the striking surface and further improve the reduced weight.

[0059] According to one embodiment of the present application, the weight-reducing structures 3 are regularly arranged on the metal structure 1, and when the weight-reducing structures are holes, the opening sizes of the holes can be consistent or varied.

[0060] According to an embodiment of the present application, the metal structure 1 is made of steel, aluminum, copper or alloy.

[0061] Through the above arrangement, the metal structure 1 of the electronic cymbal of the present application can be made of different metal materials, and for different metal structures 1, different sizes of the weight-reducing structure can be selected to achieve matching sound elimination effect, so that the design and manufacture of the present application is more flexible and diverse.

[0062] According to an embodiment of the present application, on the cymbal cap portion 11, in the radial direction from the center to the edge, a plurality of ring belt regions formed by the weight-reducing structure 3 of different sizes can be arranged on the cymbal cap portion 11, and the hole diameter of the weight-reducing structure 3 in each ring belt region is consistent, thereby producing a ring belt pattern in visual effect. In addition, a plurality of ring belt regions formed by the weight-reducing structure 3 of different sizes can also be arranged on the cymbal face portion 12, and the hole diameter of the weight-reducing structure 3 in each ring belt region is consistent, thereby producing a ring belt pattern in visual effect.

[0063] Through the above arrangement, by arranging ring belt regions formed by weight-reducing structures of different sizes on the metal structure, the weight-reducing proportion of each position on the metal structure can be made different, thereby producing different elimination effects between different regions of the metal structure for the knocking vibration, which is beneficial to reducing the knocking volume of the present application.

[0064] In the present embodiment, on the cymbal cap portion 11, in the radial direction from the center to the edge, the hole diameter of the weight-reducing structure on different ring belts is gradually increased. Similarly, on the cymbal face portion 12, in the radial direction from the center to the edge, the hole diameter of the weight-reducing structure on different ring belts is also gradually increased.

[0065] In combination with Figure 1 , Figure 2 , Figure 3 According to an embodiment of the present application, the metal structure 1 is the structural body of the electronic cymbal. If the metal structure 1 is the structural body of the electronic cymbal, the metal structure 1 is a central symmetric structure, for example, the metal structure can be circular, regular polygonal (such as square, regular hexagon) and the like.

[0066] In combination with Figure 5 , Figure 6 , Figure 7As shown, according to another embodiment of the present application, the metal structure 1 is part of an electronic cymbal. If the metal structure 1 is part of an electronic cymbal, the electronic cymbal further comprises a connecting support part 4. In this embodiment, the metal structure 1 can be in the shape of a fan, a trapezoid or other irregular shape, so that the metal structure 1 can be spliced with the connecting support part 4 to form a complete and regular electronic cymbal shape. In this embodiment, the metal structure 1 and the connecting support part 4 can be fixedly connected (for example, glued, fitted) or detachably connected (for example, buckled).

[0067] In this embodiment, the connecting support part 4 is made of a non-metal material.

[0068] Through the above arrangement, the electronic cymbal supported by the split structure, when the metal structure is struck, the vibration of the metal structure part is effectively weakened on the connecting support part, which further plays a role in suppressing the striking volume, because the connecting support part and the metal structure are made of different materials.

[0069] According to an embodiment of the present application, the connecting support part 4 can be made of relatively hard plastic 3, or can be made of a material with elasticity (for example, rubber). By using the connecting support part made of the above material, the material is relatively soft compared to the metal structure 1, and further plays a buffering role in the part connected with the metal structure 1, greatly reducing the further propagation of vibration on the metal structure 1, and further more conveniently and effectively suppressing the striking volume.

[0070] In combination with Figure 5 , Figure 6 , Figure 7 As shown, according to an embodiment of the present application, when the connecting support part 4 is connected with the metal structure 1 by using relatively hard plastic, it can be directly connected by using glue, or a buffer made of a buffer material can be arranged to fill the connecting position between the support part 4 and the metal structure 1. The hardness of the buffer material is lower than that of the plastic, so that the vibration on the metal structure 1 is weaker when it is conducted to the connecting support part 4 through the buffering effect of the buffer, which is further beneficial to suppressing the striking volume. When the connecting support part 4 is made of rubber material, because of the elastic properties of the rubber material, it has good damping effect, so that the connecting support part 4 and the metal structure 1 can be directly connected, without the need to set a buffer structure.

[0071] In combination with Figure 5 , Figure 6 , Figure 7As shown, according to an embodiment of the present application, the thickness of the connecting support part 4 can be greater than that of the metal structure 1, so that the edge of the metal structure 1 can be lapped on one side of the edge of the connecting support part 4 or embedded on the edge of the connecting support part 4. Through the above arrangement, the structural strength of the present application is ensured.

[0072] According to an embodiment of the present application, the sound-absorbing layer 2 is made of a flexible material, and the elongation at break of the sound-absorbing layer 2 is ≥ 150%, and the tensile strength is ≥ 4 MPa. In this embodiment, the sound-absorbing layer 2 is attached to the non-hitting surface of the metal structure, and when the weight-reducing structure 3 is a through hole, the sound-absorbing layer 2 can be arranged on the inner side of the through hole in whole or in part, or can not be attached to the inner side of the through hole. In this embodiment, the thickness of the sound-absorbing layer 2 applied on the metal structure is uniform, which can be arranged on the gong surface part, or arranged on both the gong surface part and the gong cap part.

[0073] Through the above arrangement, by attaching the sound-absorbing layer on the non-hitting surface of the metal structure, the stress on the hitting surface and the non-hitting surface of the metal structure can be made different, and then when the metal structure is hit, the vibration is transmitted from the hitting surface to the non-hitting surface, and then changes under the action of the attachment force of the sound-absorbing layer, thereby facilitating the vibration to be effectively absorbed after reaching the sound-absorbing layer. In addition, the sound-absorbing layer made of a material with high elongation and high tensile strength has excellent overall elastic performance, and thus the vibration generated on the metal structure can be buffered by the elasticity of the sound-absorbing layer, further enhancing the sound-absorbing effect. In addition, by using the above sound-absorbing layer, it can better adapt to the surface changes of the metal structure during vibration, thereby benefiting the attachment performance of the sound-absorbing layer and avoiding the drawback of falling off after a long time of use.

[0074] According to an embodiment of the present application, the sound-absorbing layer 2 is made of polyurea. In this embodiment, by using polyurea material, since it has a long molecular chain structure, the polyurea can play a damping and sound-absorbing role on the metal surface vibration, thereby reducing the pushing of the metal vibration on the surrounding air, thereby playing a further role in reducing the volume.

[0075] In this embodiment, the sound-absorbing layer 2 is coated on the non-hitting surface of the metal structure by thermal spraying. Among them, by using isocyanate component and amino compound two coatings through a heated hose into a special spray gun, the two are mixed rapidly in the moment of spraying, and then rapidly dried and formed on the surface of the metal structure within a few seconds, so as to realize the rapid preparation of the sound-absorbing layer. In this embodiment, the thickness of the sound-absorbing layer 2 can be sprayed according to actual requirements.

[0076] Through the above arrangement, the sound-absorbing layer is arranged on the non-hitting surface of the metal structure, which can also play a role in strengthening the metal structure, so that the metal structure can be relatively more lightened by the lightening structure. For example, when the lightening structure is a through hole, the opening on the non-hitting surface side is enlarged to further increase the lightening effect, and the attachment of the sound-absorbing layer can further eliminate the influence of the enlarged opening on the structural strength.

[0077] To further illustrate the present application, the electronic cymbal of the present application is exemplified in conjunction with the accompanying drawings.

[0078] Example 1

[0079] As shown in Figure 8 , the electronic cymbal of the present application takes the metal structure 1 as the regular main body.

[0080] In the present embodiment, the metal structure 1 is a circular structure, having a cymbal cap portion 11 and a cymbal surface portion 12. In the present embodiment, the cymbal cap portion 11 is in a middle position, and the cymbal surface portion 12 is formed around the cymbal cap portion 11 to form a central symmetric structure.

[0081] In the present embodiment, the lightening structure 3 is a through hole arranged on the cymbal cap portion 11 and the cymbal surface portion 12. Among them, in the radial direction from the center to the edge on the cymbal cap portion 11, there is only one size of lightening structure 3 formed on the cymbal cap portion 11. And on the cymbal surface portion 12, the lightening structure 3 with one aperture size forms a uniform pattern on the cymbal surface portion 12.

[0082] In the present embodiment, the lightening structure 3 on the cymbal cap portion 11 and the cymbal surface portion 12 both adopts a straight circular hole, and the aperture range is 1.5mm to 6mm.

[0083] Through the above arrangement, the metal structure 1 of the present application effectively reduces the weight by 13%.

[0084] To further verify the effect of the present application, a traditional acoustic cymbal with the same shape and size as example 1 is made as a comparison, and the sound pressure level SPL of the striking volume of the traditional acoustic cymbal is measured as 75.5dB. Compared with the traditional acoustic cymbal made, the actual test sound pressure level of example 1 when striking is less than 75.5dB and greater than 68dB. It can be seen that by setting the lightening structure as a through hole and by using the same size of punching method, a certain weight reduction of the metal structure can be achieved, and the volume is further effectively suppressed.

[0085] Example 2

[0086] As shown in Figure 9 , the electronic cymbal of the present application takes the metal structure 1 as the regular main body.

[0087] In the embodiment, the metal structure 1 is a circular structure, having a gong cap portion 11 and a gong face portion 12. In the embodiment, the gong cap portion 11 is in a middle position, and the gong face portion 12 is arranged around the gong cap portion 11 to form a central symmetric structure.

[0088] In the embodiment, the weight-reducing structure 3 is a through hole arranged on the gong cap portion 11 and the gong face portion 12. In the gong cap portion 11, only one size of the weight-reducing structure 3 is arranged to form a ring belt in the radial direction from the center to the edge. In the gong face portion 12, two different sizes of the weight-reducing structure 3 are arranged to form different ring belt patterns. The difference between the two sizes is small, so that the arrangement density of the weight-reducing structure on the gong face portion 12 is relatively large.

[0089] In the embodiment, the weight-reducing structure 3 arranged on the gong cap portion 11 and the gong face portion 12 is a straight circular hole, and the hole diameter ranges from 1.5 mm to 6 mm.

[0090] In the embodiment, the gong face portion 12 is further provided with a sound-absorbing layer 2 on the non-hitting surface, and the thickness of the sound-absorbing layer 2 is 2 mm.

[0091] Through the above arrangement, the metal structure 1 of the present application can effectively reduce the weight by 28%.

[0092] To further verify the effect of the present application, a traditional gong with the same shape and size as the gong of Example 1 is made as a comparison, and the sound pressure level SPL of the knocking volume of the traditional gong is measured to be 75.5 dB. Compared with the traditional gong, the actual test sound pressure level of the gong of Example 1 is 65.5 dB when knocking. It can be seen that by arranging the weight-reducing structure as a through hole and increasing the hole density by using smaller size intervals, a better weight-reducing effect on the metal structure can be achieved, and the sound-absorbing effect is further enhanced by combining the sound-absorbing layer.

[0093] Example 3

[0094] As shown in Figure 10 , the electronic gong of the present application takes the metal structure 1 as a regular body.

[0095] In the embodiment, the metal structure 1 is a circular structure, having a gong cap portion 11 and a gong face portion 12. In the embodiment, the gong cap portion 11 is in a middle position, and the gong face portion 12 is arranged around the gong cap portion 11 to form a central symmetric structure.

[0096] In the present embodiment, the weight-reducing structures 3 are through holes provided on the gong cap portion 11 and the gong face portion 12. The weight-reducing structures 3 are provided on the gong cap portion 11 and the gong face portion 12 in the form of through holes with different sizes. On the gong cap portion 11, in the radial direction from the center to the edge, there are two annular bands formed by the weight-reducing structures 3 with the same size of hole diameter in each annular band, which produces an annular band pattern in visual effect. In the present embodiment, on the gong cap portion 11, the hole diameter of the weight-reducing structures in different annular bands gradually increases in the radial direction from the center to the edge.

[0097] Similarly, on the gong face portion 12, different concentric annular bands are also formed by the weight-reducing structures 3 with different hole diameters. In addition, the hole diameter of the weight-reducing structures in different annular bands gradually increases in the radial direction from the center to the edge.

[0098] In the present embodiment, the weight-reducing structures 3 on the gong cap portion 11 and the gong face portion 12 are all straight circular holes, and the hole diameter ranges from 1.5 mm to 3.5 mm.

[0099] In the present embodiment, the gong face portion 12 also has a sound-damping layer 2 applied on the non-hitting surface, and the thickness of the sound-damping layer 2 is 2 mm.

[0100] Through the above arrangement, the metal structure 1 of the present application effectively reduces the weight by 30%.

[0101] To further verify the effect of the present application, a traditional original gong with the same shape and size as the gong of Example 1 is made as a comparison, and the sound pressure level SPL of the knocking volume of the traditional original gong is measured to be 75.5 dB. Compared with the traditional original gong, the actual test sound pressure level of the gong of Example 1 when knocking is 63.5 dB. It can be seen that by arranging the weight-reducing structures in the form of through holes and using different sizes in sequence, the volume can be further effectively suppressed.

[0102] Example 4

[0103] As shown in Figure 11 , the electronic gong of the present application takes the metal structure 1 as the regular main body.

[0104] In the present embodiment, the metal structure 1 is a circular structure, which has a gong cap portion 11 and a gong face portion 12. In the present embodiment, the gong cap portion 11 is in the middle position, and the gong face portion 12 is arranged around the gong cap portion 11 to form a central symmetric structure.

[0105] In the present embodiment, the weight-reducing structures 3 are through holes provided on the head portion 11 and the face portion 12. The weight-reducing structures 3 are provided in different sizes on the head portion 11 and the face portion 12, respectively. On the head portion 11, in the radial direction from the center to the edge, there are two annular bands formed by the weight-reducing structures 3 of the same size in each annular band, and the visual effect is a ring-shaped pattern. In the present embodiment, on the head portion 11, the size of the weight-reducing structures in the different annular bands gradually increases in the radial direction from the center to the edge.

[0106] Similarly, on the face portion 12, different concentric rings are formed by the weight-reducing structures 3 of different sizes. In addition, the size of the weight-reducing structures in the different annular bands gradually increases in the radial direction from the center to the edge.

[0107] In the present embodiment, the weight-reducing structures 3 on the head portion 11 and the face portion 12 are all straight circular holes, and the size ranges from 1.5 mm to 6 mm.

[0108] In the present embodiment, the non-striking surface of the face portion 12 is also provided with a sound-absorbing layer 2, and the thickness of the sound-absorbing layer 2 is 2 mm.

[0109] Through the above arrangement, the metal structure 1 of the present application can effectively reduce the weight by 33%.

[0110] To further verify the effect of the present application, a traditional original sound gong with the same shape and size as that of Example 1 is made as a comparison, and the sound pressure level SPL of the striking volume of the traditional original sound gong is measured to be 75.5 dB. Compared with the traditional original sound gong, the actual test sound pressure level of Example 1 when striking is 61.5 dB. It can be seen that by arranging the weight-reducing structures as through holes and using larger size intervals, the metal structure can be further reduced in weight, and the volume can also be effectively suppressed.

[0111] Example 5

[0112] The thickness of the sound-absorbing layer applied to the non-striking surface of the metal structure in Examples 2 to 4 is changed to further verify the effect of the thickness of the sound-absorbing layer on sound absorption. In the present embodiment, the thickness of the sound-absorbing layer 2 applied to the non-striking surface of the face portion 12 is set to 5 mm, and the density is 0.25 g / cm 3 By comparing the striking of each example, after changing the sound-absorbing layer of the present application, a further 30 dB of attenuation of the sound wave of 1-4 kHz can be achieved, and the higher the thickness of the sound-absorbing layer, the better the attenuation effect.

[0113] Example 6

[0114] Combination Figure 5 、 Figure 6 、 Figure 7 As shown in the drawings, the electronic cymbal of the present application is composed of a regular shape of a combination structure of a metal structure 1 and a connecting support 4.

[0115] In the present embodiment, the metal structure 1 is a fan-shaped structure, having a cymbal cap portion 11 and a cymbal face portion 12. In the present embodiment, the cymbal cap portion 11 is in a middle position, and the cymbal face portion 12 is formed around the cymbal cap portion 11 to form a central symmetric structure.

[0116] In the present embodiment, the weight-reducing structure 3 is a through hole provided on the cymbal cap portion 11 and the cymbal face portion 12. In the cymbal cap portion 11, only one size of the weight-reducing structure 3 is formed in a ring belt in the radial direction from the center to the edge. In the cymbal face portion 12, different ring belt patterns are formed by using two different sizes of the weight-reducing structure 3. Moreover, the difference between the two sizes is small, so that the setting density of the weight-reducing structure on the whole cymbal face portion 12 is relatively large.

[0117] In the present embodiment, the weight-reducing structure 3 on the cymbal cap portion 11 and the cymbal face portion 12 is a straight circular hole, and the hole diameter ranges from 1.5 mm to 6 mm.

[0118] In the present embodiment, the non-hitting surface of the metal structure 1 is provided with a sound-absorbing layer 2.

[0119] In the present embodiment, the proportion of the metal structure 1 as a hitting area in the whole cymbal can be adjusted as needed. In the present embodiment, the fan-shaped area of the metal structure 1 is smaller than the area of the connecting support 4.

[0120] Through the above arrangement, the metal structure 1 of the present application effectively reduces the weight by 28%, and in combination with the connecting support and the sound-absorbing layer, the actual test sound pressure level during hitting is further greatly reduced compared with the previous embodiment. It can be seen that by using the combination structure, the weight-reducing structure, and the sound-absorbing layer, the sound-absorbing effect is more obvious.

[0121] The above only describes specific solutions of the present application, and for the devices and structures not described in detail, it should be understood that the general devices and methods in the art are used to implement them.

[0122] The above only describes one solution of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
