[0033] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0034] In view of the technical problem of complex structure of the existing percussion instrument, the utility model aims at providing a digital electric drum disc with independent control panel and audio output, which integrates the sound source controller and touch element on the digital electric drum disc structure, so that the structure of the percussion instrument can be simplified under the condition of compatible sound source control and gesture touch.

[0035] The digital electric drum disc with independent control panel and audio output provided by the utility model, see Figure 1 It comprises a first drumhead assembly 1, a drum shell frame assembly 7 and a second drumhead assembly 9, the first drumhead assembly 1 and the second drumhead assembly 9 are arranged at two ends of the drum shell frame assembly 7 respectively, and form an overall housing unit of the digital electric drum disc structure.

[0036] The first drumhead assembly 1 is an upper operation surface of the whole digital electric drum disc structure, which comprises a plurality of first fixings 11, a drum rubber ring 12, a first metal drum ring 13, a first drumhead 14 and a drum frame pad ring 15.

[0037] The drum frame pad ring 15 is nested on the front face of the drum shell frame assembly 7, then the first drumhead 14 is nested on the drum frame pad ring 15, the first metal drum ring 13 is pressed and nested on the first drumhead 14, and the first metal drum ring 13 is locked on the upper drum lug 71 of the drum shell frame assembly by using the plurality of first fixings 11 to pass through the holes of the first metal drum ring 13. The drum rubber ring 12 is nested on the first metal drum ring 13.

[0038] The second drum surface assembly 9 is the lower operating surface of the entire digital drum set, which includes a plurality of second fixing members 91, a second drum surface 92 and a second metal drum ring 93.

[0039] The second drum surface 92 is nested on the reverse side of the drum shell frame assembly 7, and the second metal drum ring 93 is nested on the second drum surface 92 and is locked on the lug 71 at the bottom of the drum shell frame assembly 7 by using a plurality of second fixing members 91 passing through the holes of the second metal drum ring 93.

[0040] Here, the structure of the first fixing member 11 and the second fixing member 91 is not limited in this scheme, and as an example, it can be a screw, etc., which can be determined according to the actual situation.

[0041] Further, referring to Figure 2 , the present scheme is provided with a support frame assembly 4 on the drum shell frame assembly 7, which is stably installed inside the drum shell by setting hooks 43 on the edges.

[0042] The support frame assembly 4 includes a central mounting area 41 and six peripheral mounting areas 42, which are equidistantly and symmetrically distributed along the periphery of the central mounting area 41. At the same time, the support frame assembly 4 is integrated with a multi-point trigger unit 5, a gesture sensing unit 2, a sound source control unit 6 and a power unit 8, so that the digital drum set can be compatible with sound source control and gesture touch functions.

[0043] Specifically, the multi-point trigger unit 5 is connected with the sound source control unit 6, which includes one drum surface center trigger 51 and three drum surface edge triggers 52. The drum surface center trigger 51 is arranged on the central mounting area of the support frame assembly 4 and corresponds to the center area of the drum surface, which is mainly used for detecting the vibration signal of the center position of the head. The three drum surface edge triggers 52 are respectively arranged in the six peripheral mounting areas 41 and correspond to the edge area of the drum surface, which are used for detecting the vibration signal from the outside of the drum surface to the inside of the center of the drum surface.

[0044] The center trigger and the three triggers on the side branch together constitute a three-dimensional multi-point detection drum surface, which realizes the natural transition of tone color change from the center to the edge of the drum, so as to better simulate the rich expressiveness of the traditional drum and meet the higher pursuit of the performer for the diversity and delicacy of the tone color.

[0045] When the drumstick is struck, the trigger at the center position compares and analyzes the vibration signals of the three triggers on the side branch to determine the position of the strike and the strength of the signal, and then processes the strike vibration signal through the sound source control unit 6 to position and output different tone color changes according to different positions of the drum set.

[0046] Referring toFigures 3-4 The gesture sensing unit 2 is composed of three pieces of touch sensing elements, which are arranged on the support frame assembly and connected with the sound source control unit 6. The three pieces of touch sensing elements are respectively a first touch sensing element 21, a second touch sensing element 22, and a third touch sensing element 23.

[0047] For example, the first touch sensing element 21 is arranged at the upper left side of the support frame assembly 4 and is locked by a fixing member. The second touch sensing element 22 is arranged at the upper right side of the support frame assembly 4 and is locked by a fixing member. The third touch sensing element 23 is arranged at the lower part of the support frame assembly 4 and is locked by a fixing member.

[0048] The three triangular arc-shaped pieces are evenly distributed at an angle of 120° to ensure uniform signal sensing without dead spots. When the drum edge is struck, the gesture sensing is used to determine whether the hand is in contact with the drum surface, thereby distinguishing between horizontal edge strikes and edge strikes. When the hand is placed in the sensing area, the sound source control unit 6 inside the drum discriminates and processes the output sound at different positions.

[0049] The sound source control unit 6 is used for efficient processing and conversion of input audio signals, providing a variety of tone selection and realistic sound performance for the drum. The sound source control unit 6 includes a main board 61 and a control panel 62.

[0050] Referring to Figure 5 The main board 61 is arranged at the bottom of the support frame assembly 4 by a fixing member. The main board integrates a sound source processing chip, which is connected with the multi-point triggering unit 5 and the gesture sensing unit 2, for efficient processing and conversion of input audio signals from the multi-point triggering unit 5 and the gesture sensing unit 2, providing a variety of tone selection and realistic sound performance for the drum.

[0051] Referring to Figure 6 The control panel 62 is arranged on the side of the drum barrel frame assembly 7 and is connected with the main board 61. In some embodiments, referring to Figure 7 The control panel 62 has corresponding switch buttons 621, a display screen 622, function keys 623, a USB TYPE C charging data port 624, an audio output port 625, and a MIDI output port 626. The above-mentioned panel realizes the corresponding sound source control function.

[0052] The preferred display screen of this scheme is OLED. This display screen can clearly display various parameters and information. It can display important information such as current tone setting, volume size, and battery power in real time, allowing users to see at a glance. The use of OLED technology makes the screen have lower power consumption, higher contrast, and faster response speed, bringing users a more comfortable visual experience.

[0053] The main board 61 cooperates with the display screen 622 with OLED to form a complete built-in sound source controller, so that the electronic drum structure does not need to rely on an external electronic drum sound source control box and can be used as a separate sound source,

[0054] This controller not only allows users to directly adjust the tone, volume, and effects of the drum pad according to their own preferences, but also provides an intuitive display interface for users to easily master various settings and states. Whether on stage or in daily practice, this built-in sound source controller provides convenient and efficient operation experience for users, making the drum pad a powerful and easy-to-use percussion instrument.

[0055] In addition, for aesthetics, a metal decorative panel 63 can be preferably arranged on the control panel 62, the metal decorative panel 63 is pasted on the drum barrel frame assembly 7 corresponding to the control panel 62, and the metal decorative panel 63 is fixed on the drum barrel frame assembly 7 by a fixing member, to ensure the reliability of the assembly of the metal decorative panel 63.

[0056] The electronic drum pads on the market do not have a built-in battery power supply system, and usually use an external power supply method, which has poor portability. Based on this technical problem, the digital drum is also equipped with a built-in power supply unit 8, which provides great convenience for users. Users no longer need to find an additional charger, but only need to charge the digital drum through a common charging interface. With high charging efficiency and stable performance, it can fully charge the digital drum in a short time and ensure that the digital drum has sufficient power during use.

[0057] Referring to Figure 8 , the power supply unit 8 is arranged inside the opposite side of the support frame assembly 4, which is independently arranged. The power supply unit 8 includes a battery cover plate 81, a battery negative spring 82, a battery positive plate 83, a lithium battery 84, and a battery compartment 85.

[0058] The battery negative spring 82 and the battery positive plate 83 are respectively embedded in the clamping grooves of the battery compartment 85, the lithium battery 84 is installed in the battery compartment 85, and the two ends are in abutment with the battery negative spring 85 and the battery positive plate 83, the battery cover plate 84 is covered on the battery compartment 85, and the battery cover plate 84 is locked on the built-in battery compartment 85 by a fixing member.

[0059] The power supply unit 8 is connected with the main board 61, and the main board 61 can intelligently manage the charging and discharging process of the battery to ensure the safety and service life of the battery. When the battery has sufficient power, the battery control power supply will reasonably distribute power to provide stable power supply for each functional module of the drum pad. When the power is low, it will prompt the user to charge in time to ensure the continuous use of the drum pad.

[0060] The digital drum disc with independent control screen and audio output formed by the above scheme has the following effects compared with the prior art:

[0061] (1) The scheme realizes natural tone change from the center of the drum to the edge, better simulates the rich performance of the traditional drum, meets the higher requirements of the performer for tone change and delicate performance, and satisfies users to obtain better use experience.

[0062] (2) The built-in sound source controller can be controlled independently, the OLED menu operation is clearer, the spontaneous sound is not dependent on the external sound source control device, and the external device can be compatible.
