Description

Technical Field

[0001] The utility model relates to the technical field of bass drums, in particular to a two-stage buffer bass drum with comfortable foot feel. Background Art

[0002] Among electronic percussion instruments, the striking surface of mainstream bass drums on the market is basically composed of silicone drumheads or nylon mesh materials combined with a certain amount of foam material.

[0003] Silicone drumheads need to be molded, which has a long development cycle and high product costs. Furthermore, during use, the silicone drumheads have a short impact resistance life and feel hard to the foot, resulting in a poor user experience.

[0004] The mesh needs multiple processes to be formed, resulting in a low yield rate and high product cost. Furthermore, the mesh needs to be fixed at multiple points and tightened to give it a certain tension. The larger the mesh tension, the higher the rebound, which causes more vibration during use. At the same time, the rebound of the mesh can easily cause the drum disc to make double sounds. Furthermore, during use, the screws fixing the mesh are prone to loosening due to long-term vibration, resulting in a decrease in the mesh tension. After the mesh tension decreases, the mesh elasticity gradually decreases, resulting in a weak signal on the drum disc, and even no signal at a small force. The screws fixing the mesh at multiple points need to be retightened to restore the function of the drum disc. Therefore, we propose a two-stage cushioning bass drum with a comfortable foot feel.

[0029] 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 are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] The embodiment of the present application solves the problem that silicone drumheads need to be molded, the impact resistance life of silicone drumheads is short and the foot feel is hard during use, the mesh surface requires multiple processes to be formed, the mesh surface has high tension and high rebound, and the foot is more vibrating during use, and the rebound of the mesh surface can easily cause the drum plate to make double sounds. During use, the screws fixing the mesh surface can easily become loose due to long-term vibration, which causes the mesh surface tension to decrease and the mesh surface elasticity to gradually decrease. The screws fixing the mesh surface need to be re-tightened at multiple points to restore the function of the drum plate. The two bent parts 105 fixedly connected on both sides are realized to increase the stiffness of the front support frame 101, thereby improving the stiffness of the entire support frame assembly 1 and reducing the vibration rebound of the support frame assembly 1. Figure 1 When the force is transmitted in the forward direction, the hammer head hits the striking surface assembly 4. The striking surface assembly 4 is composed of a soft foam material, which has a vibration absorption effect, filters out unnecessary residual vibration, and ensures the transmission of the signal;

[0031] When the positive force is removed, the bass drum buffer bar 2 has a vibration-absorbing property, filtering out the rebound vibration of the support frame assembly 1, thereby ensuring that the reverse unnecessary vibration is transmitted to the sensor assembly 3, avoiding double ringing of the bass drum;

[0032] The striking surface assembly 4 is composed of multiple layers of soft foam material, which has certain elasticity and vibration absorption. During use, it avoids the hard feeling of the silicone drum surface and greatly improves the user experience.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] The embodiment of the utility model discloses a bass drum with two-stage cushioning and comfortable foot feel.

[0035] According to the attached Figure 1 As shown in Figure 5, it includes a support frame assembly 1, the support frame assembly 1 is connected to a transmission assembly, and the transmission assembly is transmission-connected to a hammer head. The support frame assembly 1 includes a front support frame 101, a side support frame 102 and a support connecting plate 104. The two ends of the side support frame 102 are respectively connected to the front support frame 101 and the support connecting plate 104 by fixing screws;

[0036] Buffer strip 2, which is provided with double-sided adhesive, and the buffer strip 2 is bonded to the front support frame 101 through the double-sided adhesive;

[0037] The striking surface assembly 4 is connected to the buffer strip 2 via the double-sided adhesive of the buffer strip 2;

[0038] The sensor assembly 3 is fixed to the back of the striking surface assembly 4 by double-sided tape;

[0039] The protective cover assembly 5 is fixed to the support frame assembly 1 by fixing screws;

[0040] The bracket connecting plate 104 is threadedly connected with a gripping screw 103, which fixes the bracket connecting plate 104 to the ground. By adjusting the gripping screw 103, the balance of the entire component can be adjusted, which facilitates placement on uneven ground and achieves a stable effect.

[0041] There are two bent parts 105 fixedly connected on both sides of the front support frame 101. The front support frame 101 is integrally formed from a 2.5-3 mm iron plate. At the same time, the two bent parts 105 fixedly connected on both sides increase the stiffness of the front support frame 101, thereby improving the stiffness of the entire support frame assembly 1 and reducing the vibration rebound of the support frame assembly 1.

[0042] The protective cover assembly 5 includes a rear protective cover 501 and a front protective cover 502. The rear protective cover 501 is connected to the front support frame 101 by fixing screws, and the front protective cover 502 is connected to the rear protective cover 501 by screws. The rear protective cover 501 is fixedly connected to the front support frame 101 by fixing screws. At this time, the buffer strip 2 is bonded to the front support frame 101 and the striking surface assembly 4, and then the sensor assembly 3 is bonded to the striking surface assembly 4. Finally, the front protective cover 502 can be connected to the rear protective cover 501 by fixing screws, and the rear protective cover 501 is connected to the front protective cover 502, and the buffer strip 2, sensor assembly 3 and striking surface assembly 4 are protected in the protective cover assembly 5.

[0043] The striking surface assembly 4 includes two layers of high-density polyurethane foam material 402 , and a high-elasticity foam material 403 is connected between the two layers of high-density polyurethane foam material 402 .

[0044] The two layers of high-density polyurethane foam material 402 are respectively bonded with a buffer support iron plate 401 and a high-molecular polyester wear-resistant mesh 404 on the side away from the high-elasticity foam material 403. The buffer support iron plate 401, the high-density polyurethane foam material 402, the high-elasticity foam material 403 and the high-molecular polyester wear-resistant mesh 404 are combined into a buffer wear-resistant assembly. This bonding and fixing method is simple to assemble and avoids the cumbersome screw fixing of the aforementioned nylon mesh. Since the high-elasticity buffer material itself has a certain rebound and reset characteristic, there is no need to repeatedly adjust the tension of the striking surface during use.

[0045] The buffer support iron plate 401 is bonded to the buffer bar 2 and the sensor assembly 3 .

[0046] When the hammer head hits the striking surface assembly 4 under the action of the transmission assembly, the positive direction of force transmission is from the striking surface assembly 4 to the sensor assembly 3, and then to the buffer bar 2 and finally to the support frame assembly 1;

[0047] When the force of the hammer head is unloaded, the direction of force transmission is exactly opposite. The rebound force of the support frame assembly 1 is first transmitted to the buffer strip 2, then to the striking surface assembly 4, and at the same time to the sensor assembly 3.

[0048] When the force is transmitted in the forward direction, the hammer head hits the striking surface assembly 4, and the striking surface assembly 4 transmits the vibration to the sensor component 3. Since the striking surface assembly 4 is composed of soft foaming materials, it has a vibration absorption effect, filters out unnecessary residual vibration, and ensures signal transmission.

[0049] When the positive force is unloaded, the support frame assembly 1 generates a rebound force due to the influence of physical properties. In order to avoid this unnecessary rebound vibration, a buffer strip 2 is provided between the support frame assembly 1 and the striking surface assembly 4. Since the bass drum buffer strip 2 is also a soft foam material with vibration absorption properties, the rebound vibration of the support frame assembly 1 is filtered out, thereby ensuring that the reverse unnecessary vibration is transmitted to the sensor assembly 3, avoiding double ringing of the bass drum.

[0050] Furthermore, the striking surface assembly 4 is composed of multiple layers of soft foam material, which has a certain degree of elasticity and vibration absorption. During use, it avoids the hard feeling of the silicone drumhead, greatly improving the user experience.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
