Description

Technical Field

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

[0002] Musical instruments are a long-standing human heritage, and their diversity continues with human progress. There are many varieties of musical instruments, including string instruments, wind instruments, keyboard instruments, and percussion instruments. With the development of science and technology and advancements in electronics, electronic instruments are increasingly appearing in our lives, such as electric guitars, electric pianos, electronic keyboards, electronic wind instruments, and electronic drums. By simulating the frequency and vibration parameters of natural musical instruments, some instruments can completely replace natural instruments, and electronic technology can also provide a wider range of timbres.

[0003] When playing an electronic drum, different timbres are often produced at different positions. For example, striking the center and edge of the drum can produce different timbres, a common playing method for electronic drums such as hand drums. Current electronic drums have a relatively simple internal sensor configuration. While striking different positions can produce different amplitudes, the single, fixed position of the sensor only allows for different sounds, resulting in minimal timbre differences. This results in insufficient overall timbre performance and leaves room for improvement. Furthermore, existing electronic drums are used solely as musical instruments, with relatively limited functionality and a need for improved practicality. Furthermore, as low-frequency instruments, electronic drums use relatively small speakers and lack a good resonance chamber, resulting in insufficient low-frequency performance. Therefore, the present invention proposes an electronic drum to at least partially address the problems that may exist in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features thereof may be combined with each other.

[0039] Please refer to Figures 1 to 7As shown, an embodiment of the present invention provides an electronic drum, comprising: a drumhead and a hollow drum body 201; the drumhead, whose cover is divided into a sound-emitting area 102 and a playing area 103, is provided with a frame 101 on its periphery, in which a circuit board 301 is provided, as well as a speaker 304 and a vibration sensor 303 electrically connected to the circuit board 301; the speaker 304 is arranged at the position of the sound-emitting area 102; the playing area 103 includes an edge playing area 132 and a central playing area 131, and the vibration sensors 303 are correspondingly provided at the positions of the edge playing area 132 and the central playing area 131; the edge playing area 132 and the sound-emitting area 102 are arranged around the outer edge of the central playing area 131; the drum body 201 is connected to the frame 101; a power interface 142 is also provided on the circuit board; the power interface 142 is exposed on the side of the frame 101.

[0040] In this embodiment, an electronic drum is provided as an improved African drum. On the one hand, it solves the problem of traditional electronic drums, which have limited timbre variation and insufficient timbre performance due to the single and fixed position of sensors. Specifically, by setting multiple vibration sensors 303 in different areas of the drum surface (edge ​​playing area 132 and center playing area 131), vibrations can be captured and processed differently according to the different striking positions. For example, the strength of the signals sensed by the sensors at the center and the edge are decoded by the circuit board 301 and emitted through the speaker to produce drum sounds of different timbres or frequencies, thereby producing a richer and more varied timbre. The speaker 304 is located in the sounding area 102 and can directly transmit the sound, reducing the loss of timbre. On the other hand, since it is mainly used as a musical instrument, by setting a power interface 142 on the circuit board 301, the electronic drum can be expanded or enhanced by external devices or power supplies, such as connecting to an audio processor, recording equipment, or other electronic music production tools, thereby improving its practicality and versatility. Furthermore, the problem of poor low-frequency performance caused by the conventional use of small speakers and lack of a resonance chamber in electronic drums is solved. The hollow drum body 201 provides a certain resonance space for the sound, which helps to enhance the fullness and depth of the low frequencies. In addition, the speaker 304 is located in the sound-generating area 102 and may use a speaker more suitable for low-frequency performance, such as a vibration speaker 304, or a combination of a vibration speaker 304 and a general-purpose speaker 304, so that it has good performance even at relatively high frequencies. For example, when not in use, the electronic drum can also be used as a sound box. By using multiple speakers and the hollow drum body 201 of the African drum, not only can the low-frequency sound performance be excellent during performance, but the sound mixing performance is also better.

[0041] In addition, a corresponding step decoding and driving circuit is provided on the circuit board 301, and the above-mentioned step decoding and driving circuit is electrically connected to the speaker 304. In addition, an audio interface can be provided, and a Bluetooth module can also be provided on the circuit board 301, so that the electronic drum can be used not only as a percussion instrument, but also as a speaker when not playing an instrument. For example, it can be used as a Bluetooth speaker by integrating the Bluetooth module.

[0042] A MIDI interface can also be provided on the circuit board 301, 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 amplifier.

[0043] It should be noted that the above-mentioned vibration speaker in this application needs to transmit vibration to a solid medium to make sound, and cannot transmit sound directly through the air. Its principle is the same as that of bone conduction speakers, while ordinary speakers use their own vibrations to drive the air to vibrate and can transmit sound to the human ear through the air.

[0044] Next, an electronic drum in this exemplary embodiment will be further described.

[0045] In the embodiment of the present application, the electronic drum cover is provided with a partition (not shown) separating the sound-generating area 102 from the playing area 103. This partition can reduce the impact of speaker vibration on the sensor. In addition, a sound-isolating pad, such as a rubber or silicone pad, can be placed inside the drumhead, below the vibration sensor 303, to further reduce the impact of speaker 304 and drum body 201 vibration on the sensor.

[0046] In the embodiment of the present application, a protective cover 202 is provided on the bottom of the drum body 201. The protective cover 202 may be made of rubber. Since the lower end of the drum body 201 is generally placed on the ground when the African drum is played, or may be directly in contact with the ground when placed normally, the lower end of the drum body 201 is covered by the protective cover 202 to prevent the drum body 201 from being moldy or damaged due to being on the ground for a long time, especially in a humid environment.

[0047] In the examples of this application, refer to Figure 1 and Figure 3 As shown, at least two vibration sensors 303 are located inside the central playing area 131 and inside the edge playing area 132. The two corresponding vibration sensors 303 are arranged in a T-shape within the central playing area 131. By having at least two vibration sensors 303 in each playing area, the position of the strokes during performance can be more accurately detected.

[0048] In the examples of this application, refer to Figure 3 and Figure 5 As shown, a gasket 302 is further provided under the vibration sensor 303; wherein, the gasket 302 corresponding to the central playing area 131 is arranged in a T shape; the gasket 302 corresponding to the edge playing area 132 is distributed around the periphery of the T shape; each of the gaskets 302 is connected to at least one of the vibration sensors 303. A gasket 302 is further provided under the vibration sensor 303 for raising the vibration sensor 303 so that the vibration sensor 303 can fully capture the vibration signal from the drumhead; wherein, the gaskets 302 corresponding to the central playing area 131 are arranged in a T-shape; the gaskets 302 corresponding to the edge playing area 132 are distributed around the periphery of the T-shape; each of the gaskets 302 is connected to at least one vibration sensor 303; through two independent playing areas, wherein the central playing area 131 is equivalent to the center position of the natural sounding drum, and similarly, the edge playing area 132 is relative to the edge position of the natural sounding drum, by striking different playing areas, the vibration sensor 303 of the corresponding playing area can capture stronger vibrations, and a corresponding processing module is set on the circuit board 301 to emit vibration audio of different frequencies and simulate the timbre of a real musical instrument.

[0049] It should be noted that, since the pitch of a naturally sounding musical instrument is essentially fixed, there are certain limitations on one or more parameters such as the instrument's size, string spacing, and hole position. Therefore, the electronic drum of the present application can reduce the instrument's size accordingly. The pitch of an instrument is related to its vibration frequency. For example, in natural tuning, when there is no sharp or flat pitch, the fixed frequency of the 6th note (la) is 440Hz. Therefore, the electronic drum of the present application can produce different and accurate tones by striking different positions.

[0050] In the examples of this application, refer to Figure 3As shown, the electronic drum also includes vibration transmission plates, which include a central vibration transmission plate 307 corresponding to the central playing area 131 and an edge vibration transmission plate 306 corresponding to the edge playing area 132. The central vibration transmission plate 307 covers and is connected to the vibration sensor 303 located in the central playing area 131, while the edge vibration transmission plate 306 covers and is connected to the vibration sensor 303 located in the edge playing area 132. The vibration transmission plates ensure that the vibration signals transmitted from the playing area to the sensors are relatively stable. For example, when striking the drumhead, it is impossible to strike precisely at the same location, such as the location of the vibration sensor 303 or a location equidistant from the vibration sensor 303. By providing the vibration transmission plates, when the striking location deviates, the vibration at each location can be more stably transmitted to the vibration sensor 303 through the vibration transmission plates, thereby enabling more stable performance of the electronic drum.

[0051] In the examples of this application, refer to Figure 1 and Figure 3 As shown, the circuit board 301 is also provided with an on / off key 141, a volume adjustment key 144, a function key 143, and an indicator light 145; the power interface 142 is a TYPE-C interface; the side of the frame 101 is provided with a side groove 104, and the on / off key 141, volume adjustment key 144, function key 143, indicator light 145, and the power interface 142 are exposed in the side groove 104. The on / off key 141 is used to control the opening or closing of the electronic drum. The TYPE-C interface can be used as a data interface and a power interface. In addition, a rechargeable battery can be set in the electronic drum, and the TYPE-C interface can also be used as a charging interface. The function key 13 is a tone switch and / or 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 the function can be switched between electronic drums and speakers by pressing the function key 13. It can also be used as a tone switching key. The above-mentioned indicator light can be used as a charging indicator light, or can also be used as a status indicator light to indicate the device status, for example, the status of the Bluetooth connection.

[0052] It should be noted that the electronic drum can directly use an external power supply, such as the above-mentioned TYPE-C interface as a power interface.

[0053] In this embodiment of the present application, a support member 305 is provided inside the frame 101, and a sound-controlled ambient light is embedded in the support member 305. The sound-controlled ambient light is electrically connected to the circuit board 301. The support member 305 and at least the drumhead located at the support member 305 are made of a transparent or translucent material. The sound-controlled ambient light can illuminate according to the rhythm and force of the drumming. During the performance, the ambient light on the drumhead can illuminate in response to the rhythm, enhancing the visual experience.

[0054] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from the other embodiments. Reference can be made to the common and similar parts between the various embodiments.
