Description

Technical Field

[0001] This utility model belongs to the field of musical instrument manufacturing technology, and specifically refers to a drum sound control device. Background Technology

[0002] In the realm of music, the snare drum, as a highly expressive and rhythmic percussion instrument, is widely used in performances of various musical styles. Whether it's a passionate rock band performance, a solemn military band ensemble, or a delicate and melodious symphonic piece, the snare drum, with its unique sonic characteristics, plays a vital role in stabilizing the rhythm, enhancing musical expression, and creating atmosphere. Its crisp, bright sound can quickly attract the listener's attention, adding vitality and tension to the entire piece of music.

[0003] However, a significant problem exists with most commercially available snare drums. Most existing snare drums lack tuning capabilities, and their sound-related parameters, such as drumhead tension and internal resonance, are essentially fixed. This results in players being limited to producing only a single timbre and pitch during performance. Regardless of the piece being played, it's difficult to adapt the snare drum's sound to suit the richness of tone required by different musical styles. For example, when playing a complex piece requiring multiple rhythmic variations and tonal layers, the lack of tuning results in a monotonous and uninspired sound, failing to convey the rich emotion and diverse nuances of the music, severely limiting the performer's expressiveness and the diversity of musical composition. Therefore, developing a device that can effectively adjust the snare drum's sound is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a drum sound control device that, through a unique sliding plate tuning mechanism and a louvered tuning mechanism, enables flexible adjustment of parameters such as drum timbre and pitch to meet the needs of different musical performances, thereby alleviating the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a drum sound control device includes a drum body, the drum body having a resonance chamber inside, and further includes:

[0006] The slide tuning mechanism includes a slide component located in the resonating chamber and operating components for controlling the slide component;

[0007] The louvered tuning mechanism includes a louvered support ring that matches the interior of the resonating chamber, multiple louvered units evenly arranged horizontally above the louvered support ring, a linkage rod for interlocking the multiple louvered units, and a drive component for driving the louvered units to rotate and locking the louvered units to a specific angle.

[0008] The present invention is further configured such that the sliding disk component includes:

[0009] The connecting shaft is positioned along the central axis of the drum body and near the bottom of the resonant cavity.

[0010] A fixing plate is sleeved on the connecting shaft. The periphery of the fixing plate is connected to the inner wall of the drum, and the fixing plate has two symmetrical sliding openings.

[0011] A sliding plate, which matches two sliding openings, is fitted onto a connecting shaft and positioned above a fixed plate;

[0012] The connecting shaft has an upper boss at the top that abuts against the sliding plate, and a lower boss at the bottom that abuts against the fixing plate.

[0013] The present invention is further configured such that the operating component includes:

[0014] The rope pin is located on the upper surface of the skateboard and near the connecting shaft.

[0015] The operating rope has one end connected to a rope pin and the other end extending out of the drum body;

[0016] A buckle is located on one side of the drum body, and the buckle is used to fix the end of the operating rope located outside the drum body.

[0017] The present invention is further configured such that a return spring for restoring the slide plate to its initial position is provided between the upper boss and the slide plate. The return spring is sleeved on the connecting shaft, and one end of the return spring is connected to the upper boss and the other end is connected to the rope pin.

[0018] The present invention is further configured such that the fixing plate is provided with limiting pins for limiting the maximum rotation range of the slide plate, and the limiting pins are symmetrically arranged on the fixing plate.

[0019] The present invention is further configured such that the louver unit includes:

[0020] Three louver panels, which, when placed horizontally, match the opening of the louver support ring;

[0021] A rotating shaft is located at the bottom of the three louver panels;

[0022] Rotary seats are distributed circumferentially on the louver support ring, and the rotary seats can be rotatably connected to both ends of each rotating shaft.

[0023] The present invention is further configured such that the linkage rod includes:

[0024] The rod is positioned between adjacent louver panels;

[0025] The linkage seat is used to allow both ends of the rod to be rotatably connected to the louver panel.

[0026] The present invention is further configured such that the driving component includes:

[0027] A mounting ring is located on the outside of the drum body, and the mounting ring corresponds to the rotating seat located in the middle.

[0030] The locking nut, which works in conjunction with the drive screw, is used to secure the drive handle.

[0031] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0032] 1. The operating rope in the operating component works in conjunction with the rope pin. Pulling the operating rope moves the slide plate along the connecting shaft. The slide plate slides within the sliding opening of the fixed plate. Because the upper boss at the top and the lower boss at the bottom of the connecting shaft limit the position of the slide plate and the fixed plate, the movement of the slide plate changes the effective volume of the resonance chamber. When the volume of the resonance chamber changes, the acoustic characteristics of the drum, such as the sound frequency, also change, improving the adjustment performance of the drum's timbre and pitch, and enriching the drum's sound expression.

[0033] 2. The drive handle in the drive assembly works in conjunction with the drive screw. Rotating the drive handle causes the drive screw to rotate the central rotating shaft. Due to the linkage rod, multiple louver units are interconnected, causing all louver panels to rotate synchronously. By adjusting the rotation angle of the louver panels, the ventilation between the resonance chamber and the outside is changed, thereby affecting the resonance effect of the drum body, achieving adjustment of the drum's timbre and volume, and improving the drum's tuning performance.

[0034] 3. Ventilation: A return spring is placed between the upper boss and the slide plate, which can restore the slide plate to its initial position after the operating rope is released, making it convenient for the next tuning operation and further improving the convenience and repeatability of tuning.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0041] Example 1:

[0042] This embodiment provides a drum sound control device, including a drum body 1, wherein the drum body 1 has a resonance chamber 2 inside, and further includes:

[0043] The slide tuning mechanism 3 includes a slide component 30 disposed in the resonance chamber 2 and an operating component 31 for controlling the slide component 30;

[0044] The louvered tuning mechanism 4 includes a louvered support ring 40 that matches the interior of the resonance chamber 2, a plurality of louvered units 41 that are evenly arranged horizontally above the louvered support ring 40, a linkage rod 42 for linking the plurality of louvered units 41 together, and a drive component 7 for driving the louvered units 41 to rotate and locking the louvered units 41 to a specific angle.

[0045] The slide assembly 30 can adjust the pitch of the drum by changing the effective volume of the resonance chamber 2. Generally, when the volume of the resonance chamber 2 decreases, the pitch of the drum will rise; when the volume increases, the pitch will fall. During performance, the performer can use the slide assembly 30 to adjust the pitch of the drum in real time according to the melody and rhythm requirements of the music, so that the sound of the drum can better match with other instruments and enhance the overall harmony of the music.

[0046] The operating component 31 allows the performer to access the internal structure without opening the drum body 1. The operating component 31 provides a remote operating method, enabling the performer to control the slide assembly 30 from outside the drum body 1.

[0047] The louver support ring 40 provides a mounting and support base for the louver unit 41, ensuring that the louver unit 41 can be stably distributed within the resonance chamber 2 and rotate according to design requirements to adjust the ventilation of the resonance chamber 2. The louver support ring 40 is typically a ring-shaped structure, its shape matching the interior of the resonance chamber 2 to ensure a tight installation. The louver support ring 40 can be tightly connected to the inner wall of the resonance chamber 2 via adhesive, bolts, or snap-fit ​​connections.

[0048] The louver unit 41 rotates to change its angle, thereby adjusting the ventilation area and ventilation state between the resonance chamber 2 and the outside world, thus affecting the resonance effect and sound characteristics of the drum body 1. The louver units 41 are evenly arranged horizontally above the louver support ring 40.

[0049] The linkage rod 42 enables multiple louver units 41 to rotate synchronously, achieving an overall ventilation adjustment effect. The linkage rod 42 is located between adjacent louver panels 410.

[0050] The driving component 7 is used to drive the louver unit 41 to rotate and lock the louver unit 41 to a specific angle to fix the ventilation adjustment state, thereby achieving precise adjustment and stable control of the drum sound.

[0051] Example 2:

[0052] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] The slide block component 30 includes:

[0054] The connecting shaft 300 is positioned along the central axis of the drum body 1 and near the bottom of the resonance cavity;

[0055] A fixing plate 301 is sleeved on the connecting shaft 300. The periphery of the fixing plate 301 is connected to the inner wall of the drum body 1, and the fixing plate 301 has two symmetrical sliding openings 302.

[0056] The slide plate 303 is matched with two sliding openings 302, and the slide plate 303 is sleeved on the connecting shaft 300 and located above the fixing plate 301;

[0057] The connecting shaft 300 has an upper boss 304 at the top that abuts against the sliding plate 303, and a lower boss 305 at the bottom that abuts against the fixing plate 301.

[0058] The connecting shaft 300 not only provides a mounting base for the fixing plate 301 and the sliding plate 303, ensuring their stable movement along the central axis of the drum body 1, but also precisely defines the axial position of the fixing plate 301 and the sliding plate 303 through the upper boss 304 at the top and the lower boss 305 at the bottom, preventing unnecessary displacement during movement. The connecting shaft 300 is a slender rod-shaped structure, positioned along the central axis of the drum body 1, with an upper boss 304 at the top and a lower boss 305 at the bottom, resembling a column with bosses. The connecting shaft 300 is located in the center of the internal resonance chamber 2 of the drum body 1 near the bottom, and its axis is completely coincident with the central axis of the drum body 1.

[0059] The fixing plate 301 is firmly fixed to the inner wall of the drum body 1, mainly playing a key role in supporting the movement of the slide plate 303 and providing it with a specific sliding path. The sliding opening 302 on it strictly limits the movement trajectory of the slide plate 303, ensuring that the slide plate 303 moves in a preset manner. The fixing plate 301 is a ring-shaped plate structure, sleeved on the connecting shaft 300, and its periphery is tightly connected to the inner wall of the drum body 1. The plate has two symmetrical sliding openings 302 to accommodate the sliding of the slide plate 303. The shape of the sliding openings 302 can be fan-shaped or other shapes. The fixing plate 301 is located inside the resonance chamber 2, sleeved on the connecting shaft 300 and fixed to the inner wall of the drum body 1, below the slide plate 303. The fixing plate 301 can be fixedly connected to the inner wall of the drum body 1 by bolt connection, glue adhesion, or welding, and can be clearance-fitted to the connecting shaft 300 for easy fine-tuning during installation.

[0060] Under the control of the operating component 31, the slide plate 303 slides flexibly along the sliding opening 302 of the fixed plate 301 on the connecting shaft 300, thereby changing the effective volume of the resonance chamber 2 and thus achieving fine adjustment of the drum sound. The slide plate 303 is generally a plate-shaped structure, the shape of which matches the sliding opening 302 on the fixed plate 301. The slide plate 303 is sleeved on the connecting shaft 300 and located above the fixed plate 301. The slide plate 303 is sleeved on the connecting shaft 300, and the sliding plate 303 can be clearance-fitted with the connecting shaft 300, allowing it to slide smoothly on the connecting shaft 300.

[0061] The performer pulls the operating rope 311, causing the slide plate 303 to slide on the connecting shaft 300. The sliding of the slide plate 303 changes the volume of the resonance chamber 2, thereby adjusting the drum sound. Once the desired drum sound effect is achieved, the operating rope 311 is fixed to the buckle 312, keeping the slide plate 303 in that position, and the drum sound is thus fixed.

[0062] Example 3:

[0063] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] The operating component 31 includes:

[0065] Rope pin 310 is located on the upper surface of slide plate 303 and near the connecting shaft 300;

[0066] The operating rope 311 has one end connected to the rope pin 310 and the other end extending to the outside of the drum body 1;

[0067] A buckle 312 is provided on one side of the drum body 1. The buckle 312 is used to fix the end of the operating rope 311 located outside the drum body 1.

[0068] The rope pin 310 is used to precisely transmit the tension applied by the operating rope 311 to the slide plate 303, thereby causing the slide plate 303 to slide on the connecting shaft 300, thus adjusting the volume of the drum resonance chamber 2 and ultimately regulating the drum sound. The rope pin 310 is generally a short columnar structure, usually with a small hole or groove on its top or side for a secure connection with the operating rope 311. The rope pin 310 is installed on the upper surface of the slide plate 303, close to the connecting shaft 300. This arrangement ensures that when the operating rope 311 is pulled, the rope pin 310 provides a stable and effective tension to the slide plate 303, guaranteeing smooth sliding of the slide plate 303. The rope pin 310 can be fixed to the slide plate 303 by welding or bolts.

[0069] The operating rope 311 is the key medium for the performer to control the slide plate 303 from outside the drum body 1. By pulling the operating rope 311, the performer moves the slide plate 303 via the rope pin 310, thereby achieving remote adjustment of the drum's timbre and pitch, providing convenience for real-time tuning during performance. The operating rope 311 is a flexible rope structure, with one end tightly connected to the rope pin 310, and the other end passing through the drum body 1 and extending outside the drum body 1, facilitating operation by the performer from the outside of the drum. One end of the operating rope 311 can be knotted and wrapped around the small hole or groove of the rope pin 310, and then secured with a buckle; alternatively, a special rope buckle can be used to connect the operating rope 311 to the rope pin 310 to ensure a stable connection.

[0070] The retaining ring 312 is used to secure one end of the operating rope 311 located outside the drum body 1. When the slide plate 303 is adjusted to a suitable position, securing the operating rope 311 to the retaining ring 312 ensures that the slide plate 303 remains stably in its current position, thereby maintaining the drum's tuning effect continuously. The retaining ring 312 is generally a ring structure and is installed on the outer surface of one side of the drum body 1. The retaining ring 312 can be fixed to the outer surface of a solid surface by bolts or adhesive. The other end of the operating rope 311 can also be secured to the outside of the retaining ring 312 by knotting.

[0071] The performer pulls the operating rope 311, which moves the rope pin 310 and the slide plate 303, changing the volume of the resonance chamber 2. When the desired drum sound effect is achieved, the operating rope 311 is fixed to the buckle 312; if further adjustment is needed, the buckle 312 is released and the operating rope 311 is pulled again.

[0072] Example 4:

[0073] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] A return spring 5 is provided between the upper boss 304 and the slide plate 303 to restore the slide plate 303 to its initial position. The return spring 5 is sleeved on the connecting shaft 300, and one end of the return spring 5 is connected to the upper boss 304 and the other end is connected to the rope pin 310.

[0075] The return spring 5 provides elasticity, restoring the slide plate 303 to its initial position after the operating rope 311 is released. This allows the slide plate 303 to automatically return to its starting state after each adjustment by the player, once the tension is no longer applied, facilitating the next adjustment and ensuring the repeatability and stability of the slide tuning mechanism 3. The return spring 5 is sleeved on the connecting shaft 300, with one end connected to the upper boss 304 at the top of the connecting shaft 300 and the other end connected to the rope pin 310 on the slide plate 303, located between the upper boss 304 and the slide plate 303. Both ends of the return spring 5 can be securely connected to the upper boss 304 and the rope pin 310 by means of hooks, welding, or embedding.

[0076] Example 5:

[0077] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] The fixed plate 301 is provided with a limiting pin 6 for limiting the maximum rotation range of the slide plate 303. The limiting pin 6 is symmetrically arranged on the fixed plate 301.

[0079] The limiting pin 6 is used to limit the maximum rotation range of the slide plate 303, preventing excessive rotation and ensuring that the slide plate tuning mechanism 3 operates safely and stably. By limiting the movement range of the slide plate 303, collisions and damage to other components due to excessive movement of the slide plate 303 can be avoided, ensuring the normal operation and service life of the drum sound control device. The limiting pin 6 is generally a slender cylinder with a large head at one end to prevent it from coming out of the mounting hole; the other end is a smooth cylindrical rod. This shape design facilitates installation on the fixed plate 301 and effectively cooperates with the structure on the slide plate 303 to achieve the limiting function. The limiting pins 6 are symmetrically arranged on the fixed plate 301 and are associated with the movement trajectory of the slide plate 303. When the slide plate 303 rotates, it will move to the position where it contacts the limiting pin 6, thereby limiting its rotation range. The limiting pin 6 can be fixed to the fixed plate 301 by interference fit or threaded connection.

[0080] Example 6:

[0081] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] The louver unit 41 includes:

[0083] Three louver panels 410, which, when placed horizontally, match the opening of the louver support ring 40;

[0084] A rotating shaft 411 is located at the bottom of the three louvered panels 410;

[0085] Rotary seats 412 are distributed circumferentially on the louver support ring 40, and the two ends of each rotating shaft 411 can be rotatably connected to each other.

[0086] The louvered panel 410 adjusts the airflow between the resonance chamber 2 and the outside by changing its angle, thereby affecting the resonance effect of the drum body 1 and adjusting the timbre and volume of the drum. There are three louvered panels 410 in total. They are flat and, when placed horizontally, match the opening of the louvered support ring 40 so as to effectively control the ventilation area when rotating. The bottom of the louvered panel 410 is connected to the rotating shaft 411, which enables a rotatable connection with the rotating base 412.

[0087] The rotating shaft 411 serves as the central axis for the rotation of the louver panel 410, allowing the louver panel 410 to rotate around it, thereby changing the angle of the louver panel 410 and adjusting the ventilation volume. The rotating shaft 411 is a slender rod-shaped structure located at the bottom of the three louver panels 410, with both ends connected to the rotating base 412. The two ends of the rotating shaft 411 are rotatably connected to the rotating base 412, such as through a shaft and bearing connection, allowing the louver panel 410 to rotate flexibly.

[0088] The rotating base 412 provides a support point for the rotating shaft 411, enabling the rotating shaft 411 to be stably mounted on the louver support ring 40 and ensuring the stability of the louver panel 410 rotating around the rotating shaft 411. The rotating base 412 is typically a block structure with mounting holes or grooves that fit at both ends of the rotating shaft 411, distributed circumferentially along the louver support ring 40. The rotating base 412 is fixed to the louver support ring 40 by welding, bolting, or snap-fit ​​connection, ensuring its stability on the louver support ring 40. Simultaneously, it is rotatably connected to the rotating shaft 411, enabling the louver panel 410 to rotate.

[0089] Example 7:

[0090] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0091] The linkage 42 includes:

[0092] The rod 420 is located between adjacent louver panels 410;

[0093] Linkage seat 421 is used to enable both ends of the rod 420 to be rotatably connected to the louver plate 410.

[0094] The rod 420 is responsible for transmitting power and motion. When a louver panel 410 begins to rotate, the rod 420 transmits this rotational motion to the adjacent louver panels 410, enabling multiple louver panels 410 to work together and change their angles, thereby adjusting the ventilation of the resonating chamber 2. The rod 420 is a simple and regular elongated structure with connecting structures at both ends that mate with the linkage seat 421. The rod 420 is located between adjacent louver panels 410, accurately spanning the gap between adjacent louver units 41, connecting the different louver panels 410 into a whole. The rod 420 is connected to the linkage seat 421 at both ends, and thus indirectly connected to the louver panels 410.

[0095] The linkage seat 421 effectively transmits the movement of the rod 420 to the louver panel 410, while also allowing the louver panel 410 to rotate freely within a certain range. The linkage seat 421 is generally a block-shaped structure located at the connection points between both ends of the rod 420 and the louver panel 410, serving as the pivot connecting the rod 420 and the louver panel 410. The linkage seat 421 can be connected to the rod 420 via shaft connection, slot connection, or other rotatable connection methods, and its other end can be connected to the louver panel 410 via welding or bolts.

[0096] Example 8:

[0097] This embodiment provides a drum sound control device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0098] The driving component 7 includes:

[0099] A mounting ring 70 is provided on the outer side of the drum body 1, and the mounting ring 70 corresponds to the rotating seat 412 located in the middle.

[0100] The drive screw 71 has one end connected to the rotating shaft 411 located in the middle, and the other end passes through the inside of the mounting ring 70 and extends to the outside of the drum body 1;

[0101] The drive handle 72 is sleeved on the drive screw 71 and located outside the mounting ring 70;

[0102] The locking nut 73, which cooperates with the drive screw 71, is used to fix the drive handle 72.

[0103] The mounting ring 70 provides a mounting base for other components of the drive assembly 7, ensuring that components such as the drive screw 71 and drive handle 72 can be stably mounted on the outside of the drum body 1. It also serves a positioning function, ensuring that the drive screw 71 accurately aligns with the rotating seat 412 located in the center. The mounting ring 70 has a ring-shaped structure and can be fixedly connected to the drum body 1 by means of bolts, rivets, or glue.

[0104] The drive screw 71, after adjustment, engages with the locking nut 73 to clamp the drive handle 72 in the middle via a threaded connection, thereby locking the louver unit 41 at a specific angle. It is a slender screw-shaped rod with a threaded end for engaging with the locking nut 73; the other end is fixedly connected to the rotating shaft 411 located in the middle. The screw has evenly distributed threads for precise transmission. The drive screw 71 is fixed to the rotating shaft 411 by a key connection, pin connection, or welding. It passes through the mounting ring 70 via a threaded or clearance fit, engaging with the drive handle 72 and the locking nut 73 on the outside of the mounting ring 70.

[0105] The drive handle 72 provides an operating interface for the user. By rotating the drive handle 72, the performer drives the stop screw 71 to rotate, thereby adjusting the angle of the louver unit 41. This allows the performer to operate the tuning mechanism from the outside of the drum body 1. The drive handle 72 is typically rod-shaped or handle-shaped, with a hole or groove at one end that mates with the stop screw 71 for easy mounting. The other end is designed for easy gripping and rotation, such as a circle or a T-shape. The drive handle 72 is connected to the stop screw 71 via interference fit, key connection, or threaded connection.

[0106] The locking nut 73 engages with the drive screw 71. After the louver unit 41 is adjusted to a suitable angle, tightening the locking nut 73 secures the drive handle 72 between the locking nut 73 and the mounting ring 70 via the threaded connection, thereby locking the louver unit 41 at a specific angle and ensuring the stability of the sound tuning effect. The locking nut 73 is connected to the drive screw 71 via threads, utilizing the friction and self-locking properties of the threads to fix the drive handle 72, thus locking the angle of the louver unit 41.

[0107] The performer turns the drive handle 72, which drives the screw 71 to rotate and drives the rotating shaft 411 to rotate, thereby adjusting the angle of the louver unit 41. After the adjustment is completed, the locking nut 73 is tightened to clamp the drive handle 72 between the locking nut 73 and the mounting ring 70.

[0108] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
