The tone is thicker, which improves the sense of layering, thickness and density of the tone, and Optimized the sound thickness of the drumhead. In addition, if the present invention is used on a drum head that has been stretched to a fixed pitch, in addition to not changing the pitch of the fixed pitch, it can also achieve the above-mentioned sound quality improvement effect.

The following describes the embodiments of the present invention in more detail with reference to the drawings and element symbols, so that those skilled in the art can implement them after studying this specification.

Please refer to FIG. 2 to FIG. 6. FIG. 2 is a perspective view of the drum ring, drum belly, and drum frame combined with the tuning ring for adjusting the tone of the drum skin according to the present invention. An exploded view of a sound tuning ring combined with a drum skin, a belly and a drum frame. FIG. 4 is a combination of a tuning ring for adjusting a drum skin sound tone and a drum skin, a belly and a drum frame according to the present invention. Top view, FIG. 5 is a cross-sectional view of the tuning ring for adjusting the skin tone sound color of the present invention combined with the drum head, belly, and drum frame to form a drum, and FIG. 6 is the tuning ring for adjusting the skin tone sound color and A partial cross-sectional view of the drum skin, belly and drum frame combined into a drum. The invention provides a tuning ring for adjusting the tone color of a drum skin sound, which includes a tuning ring body 10. The tuning ring body 10 is disposed on a bottom surface 112 of a hitting portion 11 of a drum skin 1 and defines a hole 101.

More specifically, the tuning ring of the present invention for adjusting the tone of the drum skin sound is combined with the drum skin 1, a belly 2 and a drum frame 3 to form a drum 4, such as: jazz drum, African drum, conga drum, marching Drums, Mambo drums, etc. Drum 2 surrounds a cavity 21. The drum head 1 includes the striking portion 11 and an outer ring portion 12. The hitting portion 11 includes a top surface 111, the bottom surface 112 and an outer side surface, and an edge of the bottom surface 112 of the hitting portion 11 abuts against the top of the belly 2. The outer ring portion 12 surrounds the outer side surface of the striking portion 11 and extends downward to the outer side wall of the belly 2. The drum frame 3 fixes the outer ring portion 12 of the drum skin 1 to the outer side wall of the drum belly 2. With this, the drum skin 1 can completely close the cavity 21 of the drum belly 2.

Therefore, the position of the tuning ring body 10 is not knocked and the total thickness of the combination of the tuning ring and the drum head 1 for adjusting the sound of the drum head sound of the present invention can be increased, thereby changing the original sound of the drum head 1 Features, adjust the Timbre of the sound of Drum Head 1 to reduce erratic overtones, and the waveform lasts shorter, which can show a cleaner and more concentrated sound. The tone is thicker, which improves the sense of layering and thickness of the tone. And density, and the sound thickness of the drum head 1 is optimized. Furthermore, if the present invention is used on the drumhead 1 that has been stretched and fixed, in addition to not changing the pitch of the fixed tone, it can also achieve the aforementioned sound quality improvement effect. Preferably, the above-mentioned effect is particularly significant when the thickness of the tuning ring body 10 is less than 1 mm. It is worth mentioning that when the thickness of the tuning ring body 10 is between 0.1 and 0.3 mm, in addition to having significant tuning effects, it can also reduce material costs, which is quite practical.

In a preferred embodiment, the hole 101 is opened at the center of the tuner ring body 10, and the area of the tuner ring body 10 is 20 to 40% of the area of the striking portion 11 of the drum skin 1. As a result, the layered sound of the sound emitted from the inside and outside of the striking portion 11 of the drumhead 1 is different, and the area of the tuning ring body 10 can be reduced, which is beneficial to reducing costs. In particular, when the area of the tuning ring body 10 is 25 to 35% of the area of the striking portion 11 of the drum skin 1, the above-mentioned effect can be more significant.

In a preferred embodiment, the tuning ring body 10 is circular, that is, the hole 101 is a circular hole, as shown in FIGS. 3 and 4. Thereby, the sound wave transmission distance of the tuning ring body 10 is equal, so that the sound wave transmission is the most uniform, and the tuning effect is the best.

In other embodiments, the tuning ring body 10 may have other shapes such as a polygonal ring or an irregular ring. In the embodiment in which the tuning ring body 10 is a polygonal ring, the hole 101 is a polygonal hole with a corresponding shape. In the embodiment in which the tuning ring body 10 is an irregular ring, the hole 101 is an irregular hole corresponding to the shape. In these other shapes of the tuning ring body 10, the closer to the circular ring, the closer the distance of the sound wave transmission is equal, the more uniform the transmission of the sound wave; otherwise, the less close The more unequal the distance the sound waves travel, the more uneven the sound waves travel.

In a preferred embodiment, the distance between the outer periphery of the tuning ring body 10 and the inner wall of the belly 2 is 10-40 mm. Therefore, this distance can prevent the tuning ring body 10 from contacting the belly 2 and thus can avoid the interference of the belly 2 during the tuning of the drum skin 1 to maintain its original tuning effect. Among them, when the distance between the outer periphery of the tuning ring body 10 and the inner wall of the drum belly 2 is 15-30 mm, the above-mentioned effect can be more significant.

In a preferred embodiment, the material of the tuning ring body 10 is a plastic film or a piece of paper; however, it is not limited thereto, and other materials suitable for manufacturing the film-shaped tuning ring body 10 are all included in the scope of the present invention. Let me explain first. It is important that plastic films have different characteristics due to the different plastic materials used. Among them, the plastic materials are polyvinyl chloride (PVC) plastic films and plastics. The tuning ring body 10 made of polyethylene terephthalate (PET or PETE) plastic film provides better tuning effect and more convenient material acquisition.

In a preferred embodiment, the top surface of the tuning ring body 10 is provided with an adhesive layer (not shown), and the tuning ring body 10 is fixed to the bottom surface 112 of the striking portion 11 of the drum skin 1 by the adhesive layer. After experimental tests, once the thickness of the adhesive layer exceeds 0.05 mm, the tuning effect of the tuning ring body 10 is reduced. The reason is that the adhesive layer is a soft relationship, so it will excessively absorb sound waves and suppress sound conduction. Therefore, the thickness of the adhesive layer must be controlled between 0.01 and 0.05 mm to ensure that the tuning ring body 10 exhibits an excellent tuning effect, otherwise an adverse effect will be produced. In other embodiments, the tuning ring body 10 may be fixed to the bottom surface 112 of the striking portion 11 of the drum head 1 by other fixing means.

In a preferred embodiment, the tuning ring body 10 of the tuning ring for adjusting the tone of the drum skin sound of the present invention is a single piece. In other embodiments, the tuning ring according to the present invention for adjusting the tone of the drum skin sound may further include a plurality of tuning ring bodies 10. One of the tuning ring bodies 10 is provided on the bottom surface 112 of the striking portion 11 of the drum skin 1, and the other tuning rings are provided. The bodies 10 are stacked on each other. It should be particularly noted that although the number of the tuning ring body 10 may affect the total thickness of the combination of the tuning ring and the drum head 1 for adjusting the tone of the drum skin sound of the present invention, after experimental testing, it was found that the tuning When the number of ring bodies 10 is "plural", the tuning effect is not more prominent than when the number of ring bodies 10 is "single piece". In other words, the tuning effect provided by the single-piece tuning ring body 10 is equivalent to the tuning effect provided by the plural tuning ring body 10. However, the cost of the complex tuning ring body 10 is greater than the cost of the single-piece tuning ring body 10, so the embodiment of the single-tuning ring body 10 is a preferred embodiment of the present invention.

It can be seen from FIG. 9 that the overall waveform of the sound wave emitted by the conventional drum skin 6 is more complicated, indicating that there are more overtones of uncertain intervals, and the length of the entire waveform is longer, indicating that the sound is more unstable and the erratic ending is more long. In the case of continuous tapping, more overtones and overtones are likely to be produced, and the grain performance of the sound and the feeling of concentration of power will be significantly weaker.

In contrast, the overall waveform of the sound wave emitted by the combination of the tuning ring and the drum skin 1 for adjusting the tone of the drum skin sound of the present invention is relatively simple, the erratic overtones are significantly less, and the waveform duration is shorter, representing the effective sound length Shorter, it can express a cleaner and concentrated sound, and also because the total thickness of the combination of the tuning ring and drum skin 1 for adjusting the tone of the drum skin sound of the present invention is increased, and the tone is thicker.

From the above comparison, it can be confirmed that the tuning ring of the present invention for adjusting the tone color of the drum skin has significant effects on improving the sound tone of the drum skin 1, and can present a cleaner, simpler and thicker sound quality performance.

The above are only used to explain the preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Therefore, any modification or change related to the present invention made under the same creative spirit Should still be included in the scope of the present invention.
