Description

Technical Field

[0001] This utility model relates to the field of ethnic musical instrument technology, specifically a lightweight tuning hand drum. Background Technology

[0002] The existing Xinjiang hand drums have animal leather coverings. When the air humidity is high in rainy weather, the drum skin absorbs moisture and swells and softens, making it unable to produce sound when struck and thus unusable.

[0003] Replacing animal drumheads with polyester film drumheads (synthetic drumheads) avoids the problem of animal drumheads becoming dull due to moisture because polyester film drumheads do not absorb moisture. At the same time, the tension of the drumhead can be adjusted by using screws and nuts, which allows for adjustment of the timbre and pitch when striking, thus achieving hand drum tuning.

[0004] When tuning a hand drum, the drumhead must be taut, and the drum hoop and body must withstand considerable pressure. Using metal materials ensures the structural strength of the hand drum. Therefore, without exception, these types of hand drums are made of metal materials for the drum hoop and body, commonly steel or aluminum.

[0005] The problem with all-metal hand drums is their weight. For example, a typical 40cm diameter hand drum, even made of aluminum alloy, often weighs over 1.7 kg. This weight is a considerable burden for the player, as hand drum playing is done entirely by hand. This weight requires a certain level of arm strength from the player, especially for those with weaker arm strength, causing inconvenience and difficulty in operation. Utility Model Content

[0006] In view of the current state of the prior art, the technical problem to be solved by this application is to provide a lightweight tuning hand drum, which adopts plastic material as the main structure and uses upper and lower pressure blocks made of light metal to bear the pressure of screws and nuts. While ensuring the structural strength of the hand drum, the weight of the hand drum is greatly reduced, thus achieving the lightweight design of the hand drum.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a lightweight tuning hand drum, including a drum ring, a drum body, a drumhead, an upper pressure block, a carriage screw, a lower pressure block, and a clamping nut. The drum ring has multiple upper pressure holes arranged in a ring, and the drum body has multiple lower pressure holes arranged in a ring. The upper pressure holes on the drum ring correspond one-to-one with the lower pressure holes on the drum body. The drumhead is composed of a polyester film drumhead and a metal frame. The drumhead is sandwiched between the drum ring and the drum body. The carriage screw can pass through the upper pressure block, and the clamping nut can pass through the lower pressure block. The carriage screw can be threaded into the corresponding clamping nut. The upper pressure block presses into the corresponding upper pressure hole on the drum ring, and the lower pressure block presses into the corresponding lower pressure hole on the drum body. The drum ring has an annular step inside, and the drum body has an inner annular protrusion on the inner ring.

[0008] Preferably, the drum ring and drum body are made of plastic, the upper and lower pressure blocks are made of aluminum alloy, the carriage screw and clamp nut are made of stainless steel, the lower pressure block has a central through hole, and the clamp nut can be inserted through the corresponding central through hole. The bottom end of the clamp nut has an internal hex wrench hole. The upper pressure block has a square through hole in its center. A square block is fixedly set on the lower surface of the top of the carriage screw, and the square block on the carriage screw can be locked in the corresponding square through hole. The upper pressure block has a third hollow groove inside, the lower pressure block has a fourth hollow groove inside, the drum ring has a first hollow groove inside, the drum body has a second hollow groove inside, the drum ring has a first annular reinforcing rib inside, and the drum body has a second annular reinforcing rib and multiple longitudinal reinforcing ribs inside.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, the distance between the drum ring and the drum body can be adjusted by using the clamping plate nut and the carriage screw, thereby adjusting the pressure on the drum surface clamped between the drum ring and the drum body, and adjusting the pitch produced when the drum surface is struck.

[0010] 2. In this utility model, plastic material is used instead of metal material as the main structure of the hand drum. At the same time, the internal hollowing method is adopted, which greatly reduces the weight and the operating intensity during performance. The drum ring and drum body have ring-shaped and longitudinal reinforcing ribs, which not only ensure the structural strength, but also avoid or reduce the resonance of the drum body and improve the tone of the hand drum performance. 3. In this utility model, an aluminum alloy pressure block is used to bear the tuning pressure, and the number of tuning screws and nuts is increased, and the area of ​​the pressure block is enlarged. This effectively disperses the pressure on the main plastic structure, ensuring the strength of the hand drum's plastic structure. This device adopts a three-level pressure-bearing structure. The stainless steel screws and nuts bear the main pressure, the upper and lower aluminum alloy pressure blocks bear the secondary pressure, and the plastic drum ring and drum body bear the dispersed pressure. This ensures the overall structural strength of the hand drum while making it lightweight. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-6As shown, this utility model provides a lightweight tuning hand drum, including a drum ring 1, a drum body 3, a drumhead 2, an upper pressure block 12, a carriage screw 13, a lower pressure block 32, and a clamping nut 33. The drum ring 1 has a plurality of annularly distributed upper pressure holes 11, and the drum body 3 has a plurality of annularly distributed lower pressure holes 31. The upper pressure holes 11 on the drum ring 1 correspond one-to-one with the lower pressure holes 31 on the drum body 3. The drumhead 2 is composed of a polyester film drumhead 21 and a metal frame 22, and is sandwiched between the drum ring 1 and the drum body 3. The wire 13 can pass through the upper pressure block 12, the clamping nut 33 can pass through the lower pressure block 32, and the carriage screw 13 can be threaded into the corresponding clamping nut 33. The upper pressure block 12 presses into the corresponding upper pressure hole 11 on the drum ring 1, and the lower pressure block 32 presses into the corresponding lower pressure hole 31 on the drum body 3. Multiple pressure holes (more than 12) are provided on the drum ring 1 and the drum body 3 to distribute the pressure borne by the drum ring 1 and the drum body 3, thereby ensuring the structural strength of the plastic hand drum. The drum ring 1 has an annular step 17 inside, and the drum body... The drum ring 1 is located above the drumhead 2. The annular step 17 inside the drum ring 1 presses against the edge 22 of the drumhead 2. The drum body 3 is located below the drumhead 2. The annular protrusion 40 of the drum body 3 presses against the inner surface of the drumhead 21. During tuning, the annular step 17 inside the drum ring 1 presses against the edge 22 of the drumhead 2, exerting downward pressure on the drumhead 2. The annular protrusion 40 of the drum body 3 presses against the inner surface of the drumhead 21, exerting upward pressure on the drumhead 2. The combined pressure from the drum ring 1 and the drum body 3... The drumhead 21 is tensioned, the carriage screw 13 passes through the upper pressure block 12, and the clamp nut 33 passes through the lower pressure block 32. The upper pressure block 12 presses down on the upper pressure hole 11 of the drum ring 1 from above, and the lower pressure block 32 presses down on the lower pressure hole 31 of the drum body 3 from below. When tuning, the carriage screw 13 in the upper pressure block 12 and the clamp nut 33 in the lower pressure block 32 are aligned and tightened to adjust the distance between the drum ring 1 and the drum body 3, thereby adjusting the pressure on the drumhead 2 sandwiched between the drum ring 1 and the drum body 3, and adjusting the pitch produced when the drumhead 2 is struck.

[0016] The drum ring 1 and drum body 3 are made of plastic, while the upper pressure block 12 and lower pressure block 32 are made of aluminum alloy and have an area several times larger than ordinary pads to withstand and disperse greater pressure. This application eliminates the all-metal structure of a typical tuning drum. The main structure of the drum, the drum ring 1 and drum body 3, is made of plastic, which greatly reduces the weight of the drum. At the same time, the upper pressure block 12 and lower pressure block 32, made of aluminum alloy, bear the pressure of the carriage screw 13 and the clamp nut 33. The number of carriage screws 13 and clamp nuts 33 is much greater than that of ordinary drums, which effectively disperses the pressure, ensures the overall structural strength of the drum, and avoids deformation and breakage of the plastic material under greater pressure.

[0017] Both the carriage screw 13 and the clamp nut 33 are made of stainless steel and can withstand a large adjustment force. The center of the lower pressure block 32 has a central through hole 35, and the clamp nut 33 can be inserted through the corresponding central through hole 35. The bottom of the clamp nut 33 has an internal hex wrench hole 34. The clamp nuts 33 around the drum body 3 and the carriage screws 13 around the drum ring 1 are engaged one by one. By turning the internal hex wrench hole 34 of the clamp nuts 33 around the hand drum, the pressure applied by the drum ring 1 and the drum body 3 to the drum surface 2 can be adjusted, thereby achieving the purpose of adjusting the tone and pitch of the hand drum.

[0018] The upper pressure block 12 has a square through hole 15 in its center. A square block 14 is fixedly installed on the lower surface of the top of the carriage screw 13, and the square block 14 on the carriage screw 13 can be locked in the corresponding square through hole 15. When the clamping nut 33 is rotated, the carriage screw 13 will not rotate. The upper pressure block 12 has a third hollow groove 16 inside, and the lower pressure block 32 has a fourth hollow groove 36 inside, in order to reduce the weight of the upper pressure block 12 and the lower pressure block 32. The drum ring 1 has a first hollow groove 18 inside, and the drum body 3 has a second hollow groove 39 inside, in order to reduce the weight. The drum ring 1 has a first annular reinforcing rib 19 inside, and the drum body 3 has a second annular reinforcing rib 37 and multiple longitudinal reinforcing ribs 38 inside, in order to increase structural strength and reduce resonance of the drum body 3.

[0019] Working principle: In use, the drum ring 1 is above the drumhead 2, and the annular step 17 inside the drum ring 1 presses against the edge 22 of the drumhead 2. The drum body 3 is below the drumhead 2, and the inner annular protrusion 40 of the drum body 3 presses against the inner surface of the drum skin 21. The carriage screw 13 passes through the upper pressure block 12, and the clamping nut 33 passes through the lower pressure block 32. The upper pressure block 12 presses against the upper pressure hole 11 of the drum ring 1 from above, and the lower pressure block 32 presses against the lower pressure hole 31 of the drum body 3 from below. During tuning, the carriage screw 13 in the upper pressure block 12 and the lower pressure block 32... Align and tighten the clamp nuts 33. Use an Allen wrench to turn the Allen wrench holes 34 of the clamp nuts 33 around the hand drum to adjust the pressure applied to the drumhead 2 by the drum ring 1 and the drum body 3. The inner ring step 17 of the drum ring 1 presses against the edge 22 of the drumhead 2, generating downward pressure on the drumhead 2. The inner ring protrusion 40 of the drum body 3 presses against the inner surface of the drum skin 21, generating upward pressure on the drumhead 2. The pressure generated by the combined action of the drum ring 1 and the drum body 3 causes the drum skin 21 to be tensioned, thereby achieving the purpose of adjusting the tone and pitch of the hand drum.

[0020] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The machinery, parts and equipment all adopt conventional models in the prior art, which will not be described in detail here.
