Abstract
Description
Technical Field
[0001] This utility model relates to the field of bass speaker technology, and in particular to an ultra-thin double-ring bass drum paper. Background Technology
[0002] During the sound production process, subwoofers typically generate significant resonance. Especially with the current trend of increasingly thinner subwoofers, the resonant energy within the enclosure is usually quite large, resulting in a greater impact on the main sound-producing component – the diaphragm. This causes the diaphragm to undergo significant linear deformation and amplitude, which can easily lead to harmonic distortion or produce a "popping" sound due to excessive amplitude, directly affecting the bass effect. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides an ultra-thin double-ring bass drum diaphragm. This diaphragm forms a double-surround support structure at its edge within a limited space, significantly enhancing the overall rigidity and stability of the diaphragm. This allows the diaphragm to withstand greater amplitude and power, and better control its amplitude and vibration trajectory. This enables more efficient air movement in the low-frequency range to generate stronger low-frequency sound waves, reducing harmonic distortion and non-linear deformation at the diaphragm edge. Simultaneously, it enhances the diaphragm's response speed and extends the lower limit of low-frequency response, resulting in deeper, clearer, and tighter bass sound quality with a crisper rhythm, thereby achieving the goal of enhancing bass / sub-bass sound effects.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An ultra-thin double-ring bass drum paper, applied to a speaker enclosure, includes a first support with a disc-shaped structure, on which a positioning structure is formed; wherein:
[0006] The end of the first bracket away from the speaker has a groove extending in the same direction as it on the inner side of its outline edge. The groove is connected end to end and has an outer ring that arches outward and has an arch structure.
[0007] A second bracket is detachably fixed on the end face of the first bracket away from the outer ring. The second bracket is a ring structure and is matched on the outline edge of the first bracket. The second bracket is provided with a plurality of inner rings that extend in the same direction as the outer ring and arch in the opposite direction and are connected to it. The cross-section of each inner ring is an arch bridge structure and the plurality of inner rings are evenly arrayed on the second bracket along the circumference.
[0008] As a further explanation of the above technical solution:
[0009] In the above technical solution, the outer ring and the axis of each inner ring are arranged parallel to or coincide with each other, and the axes of the inner rings are all on the same plane.
[0010] In the above technical solution, the outer ring is hot-pressed or glued to the first bracket, and the inner rings are all hot-pressed or glued to the second bracket, and the first bracket and the second bracket are hot-pressed or glued together.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an outer ring on the drum paper and cooperating with multiple inner rings to form a double-ring sound-generating component, a double-surround support structure can be formed at the edge of the drum paper in a limited space, which significantly enhances the overall rigidity and stability of the drum paper, allowing the drum paper to withstand greater amplitude and power, and better control the amplitude and vibration trajectory of the drum paper, so as to more efficiently push air in the low-frequency range to generate stronger low-frequency sound waves, reduce harmonic distortion and nonlinear deformation of the drum paper edge, and at the same time enhance the response speed of the drum paper, expand the lower limit of low-frequency response, make the bass sound quality deeper, clearer and tighter, and the rhythm more crisp, thereby achieving the purpose of enhancing the bass / sub-bass sound effect.

In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0019] like Figure 1-2As shown, an ultra-thin double-ring bass drum paper, applied to a speaker cabinet, includes a first support 1 with a disc-shaped structure. The first support 1 has a positioning structure. The end of the first support 1 away from the speaker cabinet has a groove 2 extending in the same direction as it on the inner side of its outline edge. The groove 2 is connected end to end and has an outer ring 3 that arches outward and has an arch structure. A second support 4 is detachably fixed on the end face of the first support 1 away from the outer ring 3. The second support 4 has a ring structure and is matched on the outline edge of the first support 1. The second support 4 has several inner rings 5 that extend in the same direction as the outer ring 3 and arch in the opposite direction and are connected to it. The cross-section of each inner ring 5 has an arch structure and several inner rings 5 are evenly arrayed circumferentially on the second support 4.
[0020] like Figure 3-4 As shown, the outer ring 3 and the axis of each inner ring 5 are set parallel to or coincide with each other, and the axes of several inner rings 5 are all on the same plane.
[0021] Preferably, the outer ring 3 is heat-pressed or glued to the first bracket 1, and several inner rings 5 are heat-pressed or glued to the second bracket 4. The first bracket 1 and the second bracket 4 are then heat-pressed or glued together. In this embodiment, the outer ring 3 is glued to the first bracket 1, the inner rings 5 are glued to the second bracket 4, and the first bracket 1 and the second bracket 4 are glued together.
[0022] like Figure 1-2 As shown, the positioning structure includes a first protrusion 6 and a second protrusion 7. The first protrusion 6 and the second protrusion 7 are respectively disposed on the outer walls of the first bracket 1 and the second bracket 4 and can match and overlap.
[0023] This invention creates a double-ring sound-generating component by combining an outer ring 1 with multiple inner rings 5 on the drum paper. This allows for a double-surround support structure at the edge of the drum paper within a limited space, significantly enhancing the overall rigidity and stability of the drum paper. This enables the drum paper to withstand greater amplitude and power, and better control the amplitude and vibration trajectory of the drum paper. In the low-frequency range, this allows for more efficient air movement to generate stronger low-frequency sound waves, reducing harmonic distortion and nonlinear deformation at the edge of the drum paper. It also enhances the response speed of the drum paper, extends the lower limit of the low-frequency response, and makes the bass sound deeper, clearer, and tighter, with a crisper rhythm, thereby achieving the goal of enhancing the bass / sub-bass sound effect.
[0024] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
