[0002] An electronic drum is an electronic percussion instrument that uses sound sampling technology to produce drum sounds. An electronic drum is usually composed of two parts: an electronic synthesizer and a percussion interface. The appearance is usually close to a formal jazz drum, and can also be designed into a special shape to reduce the volume. After searching, a Chinese patent authorization number CN216902230U discloses a double-layer drum skin, which relates to the field of drum skins, including a support frame, the support frame is covered with a lower drum skin, an annular clamping block is arranged on the outer side of the upper end of the support frame, the edge of the lower drum skin is located between the support frame and the annular clamping block, a mute plate is fixedly connected to the inner side of the upper end of the annular clamping block, the lower surface of the mute plate is in contact with the upper surface edge of the lower drum skin, the upper surface of the mute plate is in contact with the upper drum skin, and a filling layer is arranged in the gap between the upper drum skin and the lower drum skin. The utility model prolongs the service life of the drum skin and reduces the cost by arranging a lower drum skin and an upper drum skin. A filling layer is arranged between the lower drum skin and the upper drum skin. At the same time, a weak sound board is arranged at the edge between the lower drum skin and the upper drum skin, which can effectively reduce the residual vibration of the drum skin, does not generate repeated resonance sound, and improves the sound of the drum.

[0003] The double-layer drum skin device in the above patent has the following shortcomings: when the drum skin is damaged, it is necessary to first move the baffle downward, then remove the bolts on the convex plate, remove the clamping hoop, release the limit of the annular clamping block, and then move the annular clamping block upward to remove the lower drum skin, which makes disassembly more troublesome. At the same time, it is difficult to ensure the tension of the drum skin during installation, which affects the tone of the drum. For this reason, a double-layer electronic drum skin is designed.

[0022] In this embodiment, a plurality of second grooves are equidistantly provided on the circumferential edge of the lifting ring 8, and the second grooves are adapted to the fixed block 6, and a same sliding rod is fixedly connected between the two sides of each second groove, and each sliding rod is slidably connected in adjacent inclined holes 601.

[0023] In this embodiment, a plurality of rotating rods 9 are rotatably connected at equal intervals on the top of the lifting ring 8. The top of each rotating rod 9 is fixedly connected with an insertion rod 901 passing through the fixing ring 4. Through holes 402 matching the rotating rods 9 are opened at equal intervals on the top of the fixing ring 4.

[0024] In this embodiment, a second silicone drum skin 12 is provided on the top of the electronic drum 1, and the edge of the second silicone drum skin 12 extends to the outside of the electronic drum 1, and a mute ring 10 is fixedly connected to the top of the second silicone drum skin 12, and a filling layer 11 is fixedly connected to the top of the second silicone drum skin 12 located in the mute ring 10, and a first silicone drum skin 2 is provided on the top of the filling layer 11, and the edge of the first silicone drum skin 2 extends to the outside of the top of the electronic drum 1.

[0025] In the present embodiment, the second silicone drum skin 12 and the first silicone drum skin 2 are located on the outer side of the top of the electronic drum 1 and are provided with a plurality of fixing holes compatible with the insertion rod 901. The setting of the fixing holes and the insertion rod 901 allows the second silicone drum skin 12 and the first silicone drum skin 2 to be tightened when they are installed.
