Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a drum musical instrument. Background Art

[0002] Musical instruments are spiritual assets that humans have possessed for a long time, and they are constantly enriched with the progress of mankind. There are also many types of musical instruments, such as string instruments, wind instruments, keyboard instruments, and percussion instruments. With the development of science and technology and the advancement of electronic technology, more and more electronic musical instruments appear in people's lives, such as electric guitars, electric pianos, electronic keyboards, electronic wind instruments, and electronic drums. By simulating the frequency, vibration and other parameters of the natural sound of musical instruments, some musical instruments can completely replace natural sounding instruments, and electronic technology can also be used to make them have more timbre options.

[0003] Electronic drum instruments are a type of electronic musical instrument as well as a type of percussion instrument. They use electronic components to simulate real drum tones and timbres, and can achieve the tones and timbres of physical natural sounding instruments without using a larger volume.

[0004] In the performance of drum instruments, different positions can often produce different timbres. Specifically, striking the center position and the edge position can produce different timbres, which is also a common way of playing drum instruments such as hand drums. The current electronic drum instruments have relatively simple internal sensor settings. Although striking different positions can obtain different amplitudes, due to the single internal sensor and fixed position, they can only produce different sounds, and the timbre is not much different, so the overall timbre performance is not good enough and needs to be improved. On the other hand, the existing electronic drum instruments are only used as musical instruments, with relatively simple functions and practicality. Therefore, the utility model proposes a drum instrument to at least partially solve the problems that may exist in the prior art. Utility Model Content

[0035] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the adsorption diagram in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the adsorption diagram here can be arranged and designed in various different configurations.

[0036] In the following, some embodiments of the present application are described in detail in conjunction with the adsorption diagram. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] Please refer to Figures 1 to 5 As shown, an embodiment of the utility model provides a drum instrument, comprising: a drum body 1, a drum head 2 is provided on one side of the drum body, and a bottom plate 3 is provided on the other side of the drum body 1; a first cavity is provided between the drum body 1 and the bottom plate 3; a circuit board 19 and a speaker electrically connected to the circuit board 19 are provided in the first cavity; the drum head 2 comprises a playing area, and a sounding area 23 arranged at an edge position of one side of the playing area; the sounding area 23 is provided with a plurality of sound holes, and the speaker is located at the position of the sound holes; a vibration sensor 17 is provided at the central lower end and the edge lower end of the playing area, and the vibration sensor 17 is electrically connected to the circuit board 19, and a power interface is also provided on the circuit board.

[0038] In this embodiment, an improved drum instrument structure is provided to solve the shortcomings of traditional electronic drum instruments in terms of timbre performance. Specifically, a vibration sensor 17 is provided at the lower center end and the lower edge end of the drum head 2, which can not only detect the amplitude of the strike, but also accurately capture the strike position. The diversity of sensors enables the drum instrument to perceive richer performance details, thereby improving the expressiveness of the timbre. Due to the common playing method of the natural sounding drum, different timbres and vibration frequencies can be emitted when striking the center position and the edge position; the information captured by the vibration sensor 17 is processed by the circuit board, and by being preset in the processing module, some intelligent algorithms may be included, which can produce different timbre effects according to the strikes at different positions. For example, the output signal of the speaker can be adjusted according to the different strike positions, so that the timbre produced at the center position and the edge position is different. The speaker is located in the first cavity to ensure that the sound of the speaker is more directly transmitted to the drum surface. At the same time, the space of the cavity can make the sound emitted by the speaker produce echo enhancement in the middle, thereby enhancing the clarity of the timbre and the expressiveness of the low-frequency sound.

[0039] In addition, a corresponding step decoding and driving circuit is arranged on the circuit board, and the above-mentioned step decoding and driving circuit is electrically connected to the speaker. In addition, when an audio interface is arranged, a Bluetooth module can also be arranged on the circuit board, so that the drum instrument can be used not only as a percussion instrument, but also as a speaker when no instrument is played, for example, it can be used as a Bluetooth speaker by integrating the Bluetooth module.

[0040] A MIDI interface can also be provided on the circuit board 19, which can be used as one of the instruments in an ensemble of multiple instruments, so as to facilitate use with other instruments. In addition, the Bluetooth module can be used instead of the MIDI interface to achieve wireless connection between the instrument and the mixing console and the power amplifier.

[0041] Next, a drum instrument in this exemplary embodiment will be further described.

[0042] In the embodiments of this application, refer to Figure 2 As shown, two mounting components 4 are provided on the bottom plate 3 of the drum instrument. The mounting components 4 are provided with drum handles 5 for convenient holding. By holding the drum handles 5, the other hand directly or through a drumstick strikes the corresponding position of the playing area according to the rhythm of the music score, so that the vibration sensor 17 can obtain the corresponding striking signal, thereby triggering the corresponding sound effect, and through the driving circuit on the circuit board 19, the speaker is driven to make a sound, thereby realizing the performance of the drum instrument.

[0043] In the embodiment of the present application, the drum handle 5 is flat, and the edges of the flat drum handle 5 are designed with rounded corners, making it more comfortable to hold in hand.

[0044] In the embodiments of this application, refer to Figure 1 and Figure 3 As shown, the playing area includes a central playing area 22 and an edge playing area 21; the edge playing area 21 and the sound-generating area 23 are arranged around the outer edge of the central playing area 22; the drum body 1 at the lower end of the playing area is also provided with a second cavity 16; the second cavity 16 corresponds to the central playing area 22, and corresponds to the position of the edge playing area 21, and is provided with at least two vibration sensors 17.

[0045] In the embodiments of this application, refer to Figure 3 and Figure 5 As shown, a gasket 18 is further provided under the vibration sensor 17 for raising the vibration sensor 17 so that the vibration sensor 17 can fully capture the vibration signal from the drum head 2; wherein, the gaskets 18 corresponding to the central playing area 22 are arranged in a T-shape; the gaskets 18 corresponding to the edge playing area 21 are distributed around the periphery of the T-shape; each of the gaskets 18 is connected to at least one of the vibration sensors 17; through two independent playing areas, wherein the central playing area 22 is equivalent to the center position of the natural sounding drum, and similarly, the edge playing area 21 is relative to the edge position of the natural sounding drum, by striking different playing areas, the vibration sensor 17 of the corresponding playing area can capture stronger vibrations, and a corresponding processing module is set on the circuit board 19 to emit vibration audio of different frequencies and simulate the timbre of a real musical instrument.

[0046] It should be noted that, for natural sounding instruments, since the vibration frequency of the pitch is basically fixed, there are certain restrictions on one or more parameters of the instrument, such as the size, string spacing, and hole position. Therefore, the electronic drum instrument of the present application can reduce the size of the instrument accordingly. The pitch of the instrument is related to its vibration frequency. For example, in the case of natural tuning, when there is no sharp or flat pitch, the fixed frequency of the 6 (la) tone is 440Hz. Therefore, the drum instrument of the present application can also produce different and accurate pitches by striking different positions.

[0047] In the embodiments of this application, refer to Figure 3As shown, the instrument further includes a vibration transmission plate; the vibration transmission plate includes a central vibration transmission plate 26 correspondingly arranged in the central playing area 22, and an edge vibration transmission plate 25 correspondingly arranged in the edge playing area 21; the central vibration transmission plate 26 covers and is connected to the vibration sensor 17 located in the central playing area 22; the edge vibration transmission plate 25 covers and is connected to the vibration sensor 17 located in the edge playing area 21. Through the above-mentioned vibration transmission plates, the vibration signal transmitted from the above-mentioned playing area to the sensor is relatively stable. For example, when striking the drum surface, it is impossible to strike precisely at the same position every time, for example, the position where the vibration sensor 17 is located or the position equidistant from the vibration sensor 17. By setting the vibration transmission plates, when the striking position deviates, the vibration of each position can be more stably transmitted to the above-mentioned vibration sensor 17 through the above-mentioned vibration transmission plates, so that the drum instrument can be played more stably.

[0048] In the embodiments of this application, refer to Figure 1 and Figure 3 As shown, the side of the drum body 1 is also provided with a switch key 11 electrically connected to the circuit board 19, a volume adjustment key 14, a function key 13, an indicator light 15 and a TYPE-C interface 12. The switch key is used to control the opening or closing of the drum instrument. The TYPE-C interface 12 can be used as a data interface and a power interface. In addition, it can also be used as a charging interface. The function key 13 is a tone switch and / or a reset key. For example, the device can be reset by pressing the function key for a preset time (such as 5 seconds or 3 seconds), or by pressing the function key 13, the function can be selected to switch between the drum instrument and the speaker. It can also be used as a tone switching key. The indicator light can be used as a charging indicator light, or it can also be used as a status indicator light to indicate the device status, for example, the status of the Bluetooth connection.

[0049] It should be noted that the drum instrument can directly use an external power source, such as the above-mentioned TYPE-C interface 12 as a power interface.

[0050] In an embodiment of the present application, a secondary battery may be further arranged in the first cavity, the secondary battery being electrically connected to the circuit board 19 , and the power interface including an interface terminal connected to the secondary battery and the external TYPE-C interface 12 .

[0051] It should be noted that secondary batteries are a type of rechargeable battery, also known as rechargeable batteries or storage batteries. Unlike primary batteries (which are used once and then discarded), secondary batteries can be charged by an external power source and recharged again after discharge for reuse. Due to the reusable nature of secondary batteries, they are widely popular and also help save resources.

[0052] In the embodiments of this application, refer to Figure 2As shown, the bottom plate 3 is provided with a countersunk hole 6; the bottom plate 3 is fixedly mounted on the bottom of the drum body 1 through the countersunk hole 6 and screws. When the bottom plate 3 is installed, the screws will not protrude from the bottom plate 3, which can improve the appearance on the one hand, and on the other hand, a rubber plug can be inserted into the countersunk hole 6 after the screw is installed, which can reduce the contact between the screw and the external air and prevent the screw from rusting to a certain extent.

[0053] It should be noted that each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. Although optional embodiments of the utility model embodiments have been described, once those skilled in the art know the basic creative concept, they can make additional changes and modifications to these embodiments. Therefore, the attached claims are intended to be interpreted as including optional embodiments and all changes and modifications that fall within the scope of the utility model embodiments.

[0054] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such article or terminal device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the article or terminal device including the elements.

[0055] The technical solution provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the present invention. At the same time, for those skilled in the art, according to the principle and implementation method of the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
