Description

Technical Field

[0001] The present application relates to the technical field of membranous musical instruments, and in particular to a drum. Background Art

[0002] A membranous instrument converts membrane vibrations into sound. Generally, a membranous instrument consists of a playable membrane and a barrel-shaped cavity that holds it in place. Players typically strike the membrane with their hands or drumsticks, causing it to vibrate, which in turn drives the surrounding air to vibrate and produce sound. The membrane can be made of treated animal skin or synthetic materials.

[0003] Electronic membrane instruments are electric instruments that have evolved from traditional acoustic membrane instruments by adding a pickup. Figure 1 As shown, the musical instrument membrane 101 is fixed on the musical instrument cavity 102, and the main function of the pickup 103 is to convert the mechanical vibration of the membrane instrument, especially the mechanical vibration of the membrane, into an electrical signal. There are many types of pickups 103, including piezoelectric, electromagnetic, and microphone types. The electrical signal output by the pickup 103 can be coupled to the next level of electronic components such as the sound source 104. The sound source 104 generally detects the coupled signal to obtain multiple parameters, such as speed and force. The sound source 104 then calculates the corresponding audio electrical signal according to certain rules based on these calculated parameters. The audio point model will be further coupled to an external power amplifier such as headphones or speakers to convert it into sound that can be heard by the human ear.

[0004] Among all these calculated parameters, velocity is the most important one. The sound generator quantizes the electrical signal output by the pickup, obtains a velocity value, and then calculates the corresponding audio signal.

[0005] The traditional installation position of the pickup is near the center of the membrane. However, this method has an inherent defect, that is, when the sound is struck directly above or near the pickup, the electrical signal converted by the same force will be much stronger than that of striking other parts of the membrane. Figure 2 As shown in the figure, with the same force, the quantization value of 127 when hitting the middle point A is about twice the quantization value of 64 when hitting the non-middle point B. When this happens, the sound module cannot directly judge the force of the strike based on the original output of the pickup. Summary of the Invention

[0006] Based on this, it is necessary to provide a drum to address the above technical problems, which can output the correct force value by changing the position of the sound pickup device.

[0007] A drum comprising: a drum head, a drum bottom, a drum barrel, a force conductor, and a sensor;

[0008] The drum barrel is an annular structure, the drum surface and the drum bottom are fixed to the top and bottom of the drum barrel respectively, and the drum surface, the drum bottom and the drum barrel form a drum cavity;

[0009] The force conductor and the sensor are both arranged in the tympanic cavity;

[0010] The force conductor is a conical cylindrical structure, the large surface end of the force conductor abuts against the edge of the drum surface to prevent the force conductor from being struck, and the small surface end of the force conductor faces the sensor.

[0011] In one embodiment, it further includes: a support frame;

[0012] The support frame is arranged in the drum cavity, and the horizontal span of the support frame gradually increases along the drum bottom direction. The top of the support frame is fixedly connected to the bottom of the force conductor, and the bottom of the support frame is fixed on the drum bottom.

[0013] In one embodiment, the sensor is fixed on the force conductor or the support frame.

[0014] In one embodiment, the invention further comprises: a buffer ring;

[0015] The buffer ring is fixed between the force conductor and the drum barrel and is attached to the inner wall of the drum barrel.

[0016] In one embodiment, the buffer ring is made of silicone or rubber.

[0017] In one embodiment, the force conductor is configured as an inverted hollow truncated cone structure.

[0018] In one embodiment, the force conductor is formed by splicing.

[0019] In one embodiment, the force conductor is integrally formed.

[0020] In one embodiment, the force conductor is provided with a hollow structure.

[0021] The aforementioned drum features a force transducer designed into the sound pickup mechanism, and the location of the pickup mechanism has been relocated from the traditional center of the drumhead to the interior of the drum cavity. This prevents the user from directly striking the pickup mechanism in the center. This allows the user to accurately detect force input from any location on the drumhead, especially the center, ensuring accurate signal detection. Furthermore, requiring only a single pickup eliminates the issue of force detection when striking the center, resulting in a simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application without creative work are within the scope of protection of this application.

[0029] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the terms "first," "second," and so on, used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this application, "multiple groups" means at least two groups, such as two groups, three groups, and so on, unless otherwise specifically defined.

[0031] In this application, unless otherwise specified or limited, the terms "connect," "fix," etc. should be understood in a broad sense. For example, "fix" can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two elements or an interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] like Figures 3 and 4 As shown, a drum provided by the present application, in one embodiment, includes: a drumhead 401 , a drum bottom, a drum barrel 402 and a sound pickup device, and the sound pickup device includes: a force conductor 403 and a sensor 404 .

[0034] The drum barrel 402 is an annular structure, and the drum surface 401 and the drum bottom are fixed on the top and bottom of the drum barrel 402 respectively. The drum surface 401, the drum bottom and the drum barrel 402 form a drum cavity.

[0035] Both force transmitter 403 and sensor 404 are located within the drum cavity. Force transmitter 403 is a conical cylindrical structure, with its large end abutting the edge of the drumhead to protect it from impact, and its small end facing sensor 404. Force transmitter 403 is constructed of a hard material, such as plastic, though other materials are available depending on the application. Force transmitter 403 can be integrally formed or assembled from multiple components. Its conical surface can be continuous or feature a hollowed-out structure.

[0036] Preferably, the force conductor 403 is configured as an inverted hollow truncated cone structure.

[0037] The upper edge of the force conductor 403 is in contact with the lower surface of the drumhead, so when there is a strong blow on the drumhead, the vibration is transmitted to the sensor 404 through the force conductor 403. There is a plane contact between the force conductor 403 and the sensor 404, and there is no point contact. Therefore, there will be no sudden mutation of the detection signal at a certain point, thereby avoiding the problem of inaccurate force collection when the center is struck. The sensor 404 collects the force signal transmitted by the force conductor 403 and converts it into an electrical signal to output to the sound source.

[0038] The aforementioned drum features a force transducer designed into the sound pickup mechanism, and the location of the pickup mechanism has been relocated from the traditional center of the drumhead to the interior of the drum cavity. This prevents the user from directly striking the pickup mechanism in the center. This allows the user to accurately detect force input from any location on the drumhead, especially the center, ensuring accurate signal detection. Furthermore, requiring only a single pickup eliminates the issue of force detection when striking the center, resulting in a simple structure and low cost.

[0039] Preferably, in one of the embodiments, it further includes: a support frame 405; the support frame 405 is arranged in the drum cavity, the horizontal span of the support frame 405 gradually increases along the drum bottom direction, the top of the support frame 405 is fixedly connected to the bottom of the force conductor 403, and the bottom of the support frame 405 is fixed on the drum bottom.

[0040] In this embodiment, the support frame 405 is fixed on the drum bottom, and can be fixed by using screws and nuts or other fixing methods well known in the industry.

[0041] The force conductor 403 is fixed on the support frame 405, and can be fixed by using screws, nuts, buckles or other fixing methods well known in the industry.

[0042] The sensor 404 is fixed on the force conductor 403 or the support frame 405 , and can be fixed using adhesive materials such as glue or double-sided tape or other fixing methods known in the industry.

[0043] In one embodiment, the drum further includes a buffer ring 406 . The buffer ring 406 is fixed between the force transmitter 403 and the drum 402 and adheres to the inner wall of the drum 402 . The buffer ring 406 is made of an elastically deformable material, such as silicone or rubber. The thickness of the buffer ring 406 is equal to the minimum distance between the force transmitter 403 and the drum 402 . The buffer ring 406 can be secured to the drum 402 using glue or double-sided tape.

[0044] The function of the buffer ring 406 is to isolate the force conductor 403 from the drum barrel, to minimize the transmission of vibration of the force conductor 403 to the drum barrel 402, and to also minimize the transmission of vibration of the drum barrel 402 to the force conductor 403.

[0045] This application does not limit the sizes of related components such as the force conductor 403, the conductor 404, the support frame 405 and the buffer ring 406, and can be specifically designed according to actual needs.

[0046] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
