[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0030] Reference Figures 1 to 4 The utility model provides a bass drum, comprising:
[0031] A mesh surface 10, which is fixed to the drum body by a pressing ring 11, and is used to directly bear the force of the hammer head;
[0032] The trigger unit 20 is disposed on the back of the mesh surface 10. When the hammer hits the mesh surface 10, the trigger unit 20 is hit through the mesh surface 10.
[0033] A first fixing plate 30, used to fix the trigger unit 20, the trigger unit 20 and the first fixing plate 30 are rigidly connected;
[0034] The shock-absorbing sponge 40 is filled in a part of the space between the mesh surface 10 and the first fixing plate 30. There is a gap between the mesh surface 10 and the first fixing plate 30, and the shock-absorbing sponge 40 is arranged in the gap. It should be noted that the shock-absorbing sponge 40 only exists in a part of the space of the gap; specifically, the shock-absorbing sponge 40 is attached to a side of the first fixing plate 30 facing the mesh surface 10;
[0035] The second fixing plate 50 and the first fixing plate 30 are connected to the second fixing plate 50 via a plurality of shock absorbing pads 60 , and the shock absorbing and buffering direction of the shock absorbing pads 60 is parallel to the triggering force direction of the trigger unit 20 .
[0036] The connection points between the second fixing plate 50 and the first fixing plate 30 are evenly distributed on the outer edge of the first fixing plate 30. The second fixing plate 50 and the first fixing plate 30 are softly connected. The shock-absorbing pad 60 has a shock-absorbing and buffering effect. When the hammer hits the mesh surface 10, the force is transmitted from the mesh surface 10 to the trigger unit 20, and the trigger unit 20 is transmitted to the first fixing plate 30. The first fixing plate 30 compresses the shock-absorbing pad 60 to softly transmit the violent striking force to the second fixing plate 50, and the second fixing plate 50 is then transmitted to the wooden ring 12 of the bass drum. In order to reduce rebound and improve foot feel, the shock-absorbing and buffering action direction of the shock-absorbing pad 60 is parallel to the trigger force direction of the trigger unit 20, reducing the force rebound phenomenon in the striking direction, isolating the source of vibration and damping to suppress double rings.
[0037] Combination Figure 2 As an implementation mode, the shock-absorbing pad 60 is respectively clamped with the first fixing plate 30 and the second fixing plate 50, and then fixed by the fixing bolts 13. A first buffer space 61 and a second buffer space 62 are provided in the shock-absorbing pad 60. The arrangement direction of the first buffer space 61 and the second buffer space 62 is parallel to the trigger force direction of the trigger unit 20. The first buffer space 61 and the second buffer space 62 are both spaces constructed by using the dielectric material in the shock-absorbing pad 60. The two buffer spaces are used to improve the shock-absorbing effect of the two-way relative movement between the first fixing plate 30 and the second fixing plate 50.
[0038] Combination Figure 2 Preferably, the first buffer space 61 is located in the inner area of the shock-absorbing pad 60 between the first fixed plate 30 and the mesh surface 10, and the second buffer space 62 is located in the inner area of the shock-absorbing pad 60 between the first fixed plate 30 and the second fixed plate 50. From the cross-section, the first buffer space 61 is located between the first fixed plate 30 and the mesh surface 10, and the second buffer space 62 is located between the first fixed plate 30 and the second fixed plate 50. In the striking state, the second buffer space 62 is compressed and the first buffer space 61 will expand; in the rebound state, the first buffer space 61 is compressed and the second buffer space 62 will expand; under the joint action of the two buffer spaces, the softness of force transmission between the first fixed plate 30 and the second fixed plate 50 is improved, and the energy absorption effect is good, reducing the rebound phenomenon.
[0039] Preferably, in the assembled state, the accommodation volume of the first buffer space 61 is larger than the accommodation volume of the second buffer space 62 , so as to improve the energy absorption effect of the first buffer space 61 and further improve the isolation effect against rebound.
[0040] Preferably, the number of the shock-absorbing pads 60 is not less than 3, and the connection points thereof are evenly distributed on the outer edge of the first fixing plate 30 .
[0041] Preferably, the shock absorbing pad 60 is made of silicone.
[0042] Combination Figure 3 Preferably, the trigger unit 20 is embedded in the shock-absorbing sponge 40, both ends of the trigger unit 20 are exposed on two sides of the shock-absorbing sponge 40, and the shock-absorbing sponge 40 surrounds the trigger unit 20 circumferentially, thereby improving the shock-absorbing effect between the first fixing plate 30 and the mesh surface 10.
[0043] In summary, compared with the prior art, the above embodiment provides a bass drum that provides dual shock absorption by arranging a shock-absorbing sponge 40 and a shock-absorbing pad 60. The shock-absorbing sponge 40 absorbs the vibration between the mesh surface 10 and the first fixed plate 30, and the shock-absorbing pad 60 is used to realize the force transmission between the first fixed plate 30 and the second fixed plate 50. It can realize the switching between fierce striking force and soft transmission force, improve the softness of the foot feel, and also suppress the double sound problem.
[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
