Background

Drum set (Drum set) is a common type of percussion instrument, and includes Bass drums (Bass Drum), snare drums (Snare Drum), hi-Hat, tomtomtom, and Cymbal. The kind, number and configuration form of the toms and the cymbals can be freely changed according to the taste of the user.

Fig. 1 is a perspective view showing a general drum kit structure.

The structure of a drum kit 10 that is mainly used in general is shown in fig. 1, illustrating an example in which the drum kit 10 is made up of a bass drum 11, a snare drum 12, a hi-hat, three

toms

14, 15, 16, and two

cymbals

17, 18.

In the example of fig. 1, three

toms

14, 15, 16 consist of a snare drum (Small tom) 14, a Middle drum (Middle tom) 15, a grand drum (Large tom) or a Floor drum (Floor tom) 16, respectively, and two

cymbals

17, 18 consist of a high Cymbal 17 and a rhythm Cymbal 18.

However, the drum kit constructed as described above is expensive, is not easily purchased by general users, has a large overall volume, and is not easily moved, thereby causing a problem in that time and place required for a user to perform or practice are greatly limited.

To solve these problems, various electronic drums, which are relatively inexpensive and have a reduced overall size as compared to the conventional acoustic drum kit, have been increasingly used.

For example, korean registered utility model publication No. 20-0479551 (speaker integrated electronic drum) (2016 publication No. 2/11/2016) discloses a structure in which a plurality of drums and small cymbals, electronic drums of speaker modules are provided on a shelf device composed of a plurality of racks and a shelf. However, the electronic drum disclosed in the registered utility model publication still has a large volume as a whole, and thus has a problem of low portability.

To solve these problems, a drum-pad type electronic drum having a plurality of pads corresponding to a plurality of drums and cymbals constituting a drum kit is continuously developed.

For example, korean laid-open patent publication No. 10-2019-0079130 (electronic drum) (published 7/5 in 2019) discloses a drum pad type electronic drum in which when a plurality of drum pads are struck with a stick, electronic sounds corresponding to the respective drum pads are output through speakers.

However, the pad type electronic drum disclosed in the above-mentioned patent publication has an advantage that it is smaller in size and more portable than the conventional electronic drum, but in the configuration in which a plurality of pads are arranged adjacent to each other on one pad, when a user strikes a specific pad with a stick, the impact is transmitted to the adjacent pad, and an erroneous operation such as erroneous recognition that the pad is struck is likely to occur.

In particular, the conventional drum pad type electronic drum has a problem that, when the striking to a specific drum pad is too strong, an impact is transmitted to an adjacent drum pad, thereby causing an erroneous operation, and when the striking to a specific drum pad is too weak, it is impossible to determine whether the impact is actually struck by a stick or transmitted from an adjacent drum pad, thereby causing an erroneous operation.

Therefore, there is a need for an electronic drum that can finely divide the striking strength of the drum pad, can adjust the strength in a wider range, and can improve the sense of reality and realism as if the drum set is actually played when the electronic drum is played.

The terms "direction" and "expression" used in the present invention are used only for simplifying the description of the present invention, and do not mean that the direction of the related device or element (for example, "front", "back", "up", "down", "top", "bottom", "left", "right", "horizontal") and the like).

The present invention will be described below with reference to the accompanying drawings illustrating an electronic drum according to an embodiment of the present invention.

Fig. 2 is a perspective view showing an electronic drum structure according to an embodiment of the present invention, and fig. 3 is a plan view showing an electronic drum structure according to an embodiment of the present invention.

As shown in fig. 2 and 3, the electronic drum 100 according to an embodiment of the present invention may include a drum body 110, a plurality of drum pads 120, a sound generation unit 130, and a sound output unit 140.

The drum body 110 is a main body constituting the electronic drum 100, and has a plurality of drum pads 120 disposed on an upper surface thereof, a sound generation unit 130 disposed inside thereof, and a sound output unit 140 disposed on at least one side thereof. Although fig. 2 shows an example in which the drum body 110 is configured to have a constant volume, it may be formed of a flexible material such as silicone rubber, and may be formed into a slightly thin pad shape.

A plurality of pads 120 are provided on the upper surface of the drum body 110, and each pad 120 may be provided in a position corresponding to a Snare drum (Snare drum), a Hi-Hat (Hi-Hat), a plurality of tomtomtom (Tomtom), and a plurality of Cymbal (Cymbal) constituting an actual drum kit.

As shown in fig. 2, each of the pads 120 is formed of a flexible material such as silicone rubber, has a cross section of a predetermined shape (circular shape in the example of fig. 2), and can be formed in a shape protruding from the drum body 110 by a predetermined height.

An example in which the plurality of pads 120 are each formed in a circular section is illustrated in fig. 2, but is not limited thereto, and it is well within the ability of a person of ordinary skill in the art to modify the respective sectional shapes of the plurality of pads 120. Although fig. 2 illustrates an example in which the plurality of pads 120 are formed in a similar size, they may be formed in different sizes as needed. Although an example in which the plurality of drum pads 120 are each formed at the same height is illustrated in fig. 2, the respective heights of the plurality of drum pads 120 may be differently set according to the need.

Each of the pads 120 is a sound generation section 130 that can generate sounds corresponding to a snare drum, a hi-hat, a plurality of toms, and a plurality of cymbals constituting an actual drum kit when a user is struck by a pair of drumsticks S.

Preferably, the plurality of drum pads 120 may generate a voltage signal according to the striking intensity of the user. To this end, each of the drum pads 120 may include a piezoelectric element 122 that senses a striking by the user and generates a voltage signal according to the striking intensity of the user. The structure of the drum pad 120 will be described in detail later with reference to fig. 7 and 8.

The sound generation unit 130 is disposed inside the drum body 110, is connected to each of the plurality of pads 120, and generates sound corresponding to each of the plurality of pads 12 when the plurality of pads 120 are struck.

Fig. 4 is a block diagram showing a structure of a sound generation unit constituting an electronic drum according to an embodiment of the present invention.

As shown in fig. 4, the sound generation part 130 may include a MIDI (musical instrument digital interface) controller 131 and a sound source controller 132.

The MIDI controller 131 may generate a MIDI signal corresponding to the voltage signal transmitted by the piezoelectric element 122 of the drum pad 120 struck by the user among the plurality of drum pads 120. Here, the MIDI signal is a MIDI value preset in accordance with the striking intensity of the user in correspondence with the voltage signal detected from the piezoelectric element 122, and may have a digital form.

Preferably, MIDI controller 131 generates a MIDI signal corresponding to the voltage signal only when the voltage signal transmitted from piezoelectric element 122 is equal to or greater than a preset reference value. Since the voltage signal detected from the piezoelectric element 122 of a specific drum pad 120 is generated not by the user's striking but by the vibration (impact) transmitted by the adjacent drum pad 120 when it is lower than the reference value or less, the malfunction of the drum pad 120 is prevented.

The sound source controller 132 generates a preset sampling sound based on the key position information and intensity information included in the MIDI signal transmitted from the MIDI controller 131, and generates a sound corresponding to the struck drum pad 120.

Here, the key position information is information on the pad 120 struck by the user, and includes the kind, position, and the like of the pad 120, and the intensity information may include the striking intensity detected from the piezoelectric element 122 of the pad 120 struck by the user. The sampling sound is a sound set in advance for key position information and intensity information of MIDI information, and may have a digital form.

On the other hand, as shown in fig. 4, the sound generation section 130 may further include an enhancer 133 for enhancing the sound (sampled sound) generated by the sound source controller 132, as necessary.

Next, the operation of the sound generation unit 130 constituting the electronic drum 100 according to an embodiment of the present invention will be described in detail with reference to fig. 5 and 6.

Fig. 5 is a sequence diagram showing the operation of the sound generation unit of the electronic drum according to the embodiment of the present invention, and fig. 6 is a schematic diagram showing the operation of the sound generation unit of the electronic drum according to the embodiment of the present invention.

As shown in fig. 5, the MIDI controller 131 of the sound generation unit 130 transmits a voltage signal from the piezoelectric element 122 of the drum pad 120 struck by the user, and can determine whether the voltage signal is equal to or greater than a predetermined reference value S110.

According to the determination result of step S110, when the voltage signal transmitted from the piezoelectric element 122 of the drum pad 120 struck by the user is equal to or greater than the preset reference value, the MIDI controller 131 may generate the MIDI signal S120 corresponding to the voltage signal of the drum pad 120 struck by the user.

In fig. 6, the voltage signal number detected by the piezoelectric element 122 is divided into 5 steps, and the preset value is represented by P ₀ For example. Fig. 6 shows an example in which MIDI signals M2, M3, M4, and M5 are set for P2, P3, P4, and P5 when the voltage signal detected by the piezoelectric element 122 corresponds to the value or range of P2, P3, P4, and P5, respectively.

First, as shown in fig. 6, the voltage signal of the drum pad 120 struck by the user is at a preset reference value P ₀ Below (or less than) the value, the MIDI controller 131 judges that the voltage signal is generated by the vibration transmitted from the adjacent drum pad 120, and thenThe MIDI signal is not generated but is ignored. In contrast, the voltage signal of the drum pad 120 struck by the user is at the preset reference value P ₀ If the voltage is equal to or higher than the predetermined value (or higher than the predetermined value), the MIDI controller 131 may generate a MIDI signal set to the voltage signal.

For example, in the example of fig. 6, when the voltage signal of the drum pad 120 struck by the user corresponds to the value or range of P1, P1d is at the preset value P ₀ Hereinafter, therefore, if the MIDI controller 131 does not generate the MIDI signal and the voltage signal of the drum pad 120 struck by the user corresponds to the value or range of P3, P3 is at the reference value P set in advance ₀ As described above, the MIDI controller 131 can generate the MIDI signal M3 set to the voltage signal P3.

Referring again to fig. 5, the sound source controller 132 of the sound generator 130 generates a MIDI signal corresponding to the voltage signal of the pad 120 struck by the user by the MIDI controller 131, and then generates a preset sampling sound based on the key position information and the intensity information of the MIDI signal S120, thereby generating a sound corresponding to the struck pad 120.

Fig. 6 shows an example in which sampling sounds S2, S3, S4, and S5 are set for MIDI signals M2, M3, M4, and M5, respectively. The sound source controller 132 generates a sampling sound S3 set in advance from the key position information and intensity information of the MIDI signal M3 generated for the voltage signal P3 of the drum pad 120 struck by the user, thereby generating a sound.

As described above, in the sound generation unit 130 constituting the electronic drum 100 according to an embodiment of the present invention, after the MIDI controller 131 generates the MIDI signal in the digital form corresponding to the voltage signal of the drum pad 120 struck by the user, the sound source controller 132 generates the preset analog form sampling sound based on the key position information and the intensity information of the MIDI signal, so that the voltage signal detected from the piezoelectric element 122 of the drum pad 120 is further finely divided, and a sound similar to an actual drum set is output.

Referring again to fig. 2 and 3, the sound output unit 140 is disposed on at least one side of the drum body 110, connected to the sound generation unit 130, and converts the sound transmitted from the sound generation unit 130 into an analog form to be output when the plurality of pads 120 are struck by the user. Fig. 2 shows an example in which a pair of acoustic output units 140 are provided on both sides of the upper end of the drum body 110, but those skilled in the art can modify the number, arrangement, and the like of the acoustic output units 140.

The structure of the drum pad 120 constituting the electronic drum 100 according to an embodiment of the present invention will be described in detail with reference to fig. 7 and 8. As described above, the plurality of drum pads 120 may include the piezoelectric element 122 required to generate a voltage signal according to the striking intensity of the user.

Fig. 7 is an exploded perspective view showing a drum pad structure constituting an electronic drum according to an embodiment of the present invention, and fig. 8 is a longitudinal sectional view showing the drum pad structure constituting the electronic drum according to an embodiment of the present invention.

As shown in fig. 7 and 8, each drum pad 120 may include a pad plate 121, a piezoelectric element 122, a pad body 123, and a circuit substrate 124.

The pad 121 is struck by a user, and may be entirely made of a flexible material such as silicone rubber, and may be formed into a thin plate shape having a cross section of a predetermined shape (circular shape in the example of fig. 7). Preferably, the pad 121 is formed to concentrate the strength of the striking by the user, i.e., the striking strength by the stick S, and may include an iron plate 121a adjacent to the piezoelectric element 122 in a flexible material such as silicon.

The piezoelectric element 122 is disposed to be contactable to a lower portion of the pad 121, and generates a voltage signal according to the striking intensity of the pad 121. The pad body 123 has a pad plate 121 coupled to an open upper end thereof, and a receiving space 123a for disposing the piezoelectric element 122 may be formed therein.

The circuit board 124 is disposed at the lower end of the pad 123 separately from the piezoelectric element 122, is electrically connected to the piezoelectric element 122, and transmits a voltage signal transmitted from the piezoelectric element 122 to the MIDI controller 131. Such a Circuit Board 124 may be a Printed Circuit Board (PCB) or a Flexible Printed Circuit Board (FPCB).

On the other hand, the drum pad 120 may further include an elastic member that reduces vibration caused by the pad plate 121 being struck. As shown in fig. 7 and 8, the elastic member is disposed in the receiving space 123a of the pad 123 and covers the piezoelectric element 122, and may be made of a sponge material.

Such an elastic member is a phenomenon for preventing vibration (impact) occurring when the pad plate 121 is struck by a user from being transmitted to the piezoelectric element 122 of the adjacent drum pad 120, and can solve a problem that the piezoelectric element 122 of the adjacent drum pad 120 judges the vibration as the user striking. The drum pad 120 can sufficiently improve the strength of the impact by the user through the elastic member.

On the other hand, the circuit substrate 124 provided on the drum pad 120 may include a light emitting member 124a that emits light outward through the pad body 123 when the pad plate 121 is struck. Further, the light emitting member 124a is configured such that when the pad 121 is struck by a user, a voltage signal detected from the piezoelectric element 122 is at a predetermined reference value P ₀ In the above case, when the sound generation unit 130 generates sound according to the striking intensity of the user, light is emitted to the outside, and the voltage signal detected from the piezoelectric element 122 is at the preset reference value P ₀ In the following, light is not emitted, and it is confirmed that the user has correctly struck the pad 121.

As described above, in the electronic drum 100 according to an embodiment of the present invention, when a specific pad 120 among the plurality of pads 120 provided on the electronic drum 100 is struck, the MIDI signal is generated from the voltage signal based on the striking intensity, and the preset sampling sound output is generated based on the key position information and the intensity information of the MIDI signal, so that the striking intensity of the pad 120 is further finely divided, and thus, the sense of reality and reality as an actual drum set can be improved when playing the electronic drum 100.

The utility model provides an electronic drum 100 is, when specific drum pad 120 is hit in a plurality of drum pads 120 that possess on electronic drum 100, according to the stereo set of striking intensity output difference each other, and adjacent drum pad 120 can not transmitted in addition in the vibration, can carry out the strong and weak regulation of wideer scope during striking drum pad 120 to realize the performance similar with actual performance shelf drum.
