Description

Technical Field

[0001] The utility model relates to the technical field of sound column sealing, in particular to a sound column structure. Background Art

[0002] The core of a column speaker is a cylindrical sound box composed of multiple speakers arranged and connected in phase. The sound of each speaker is coordinated to form a unified sound effect, making column speakers widely used in various occasions such as music, theaters, and conference rooms.

[0003] Maintaining an airtight seal between the sound column and the enclosure is crucial, as air leakage can affect a speaker's acoustic performance, such as bass response and efficiency. To address this issue, sealing rings are typically installed at opposite ends of the sound column. However, installing these rings requires expertise and precision. Lack of standardized procedures or inadequate operator skills can lead to oversights, such as omission or incorrect placement. These subtle oversights, difficult to detect immediately, can compromise the sound column's sealing performance, leading to more serious equipment failure. Utility Model Content

[0004] Based on this, the utility model provides a sound column structure with a simple structure and easy assembly. The end cover is positioned and installed using a pad. During installation, you can intuitively feel whether the pad and the end cover have been installed correctly, thereby reducing the possibility of missing installation. At the same time, the sealing ring is eliminated, making the installation process faster and more convenient, reducing the possibility of human error, and ensuring the sealing performance of the sound column.

[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 6 , is a sound column structure of an embodiment of the present invention, comprising a sound column box 10, pads 20 mounted on opposite ends of the sound column box 10, and end covers 30 matched and mounted on a side of the pads 20 facing away from the sound column box 10.

[0030] The column sound box 10 is hollow, and the inner walls on opposite sides of the column sound box 10 are respectively connected with support ribs 11 in a T-shape, and the support ribs 11 are used to support the pad 20; the opposite ends of the front side of the column sound box 10 are respectively protruded with plugs 12, and the plugs 12 are used to position and connect the pad 20.

[0031] A through hole 21 roughly in the shape of a convex character is provided in the middle of the pad 20 , and a slot 22 is provided on one side of the pad 20 corresponding to the through hole 21 , for the insert 12 to pass through.

[0032] A first flange portion 23 is provided on the side of the backing plate 20 facing the sound box 10, corresponding to the periphery of the through hole 21. Openings 230 are provided on opposite sides of the first flange portion 23. The openings 230 are used to correspondingly avoid the support ribs 11. A second flange portion 24 is provided on the side of the backing plate 20 facing away from the sound box 10, corresponding to the periphery of the through hole 21. The second flange portion 24 is used to position and install the end cap 30.

[0033] In this embodiment, a plurality of alignment holes 25 are provided at intervals on one side of the backing plate 20 corresponding to the slot 22 . The alignment holes 25 are located on a side of the slot 22 away from the through hole 21 . The alignment holes 25 are used to position and connect the end cap 30 .

[0034] In this embodiment, a plurality of first via holes 26 are spaced apart around the pad 20 corresponding to the through hole 21 .

[0035] The end cap 30, facing the backing plate 20, features a roughly "convex"-shaped insert ring 31. This insert ring 31 fits snugly within the through-hole 21, with its outer wall tightly abutting the inner wall of the through-hole 21. The outer wall of the insert ring 31 also tightly abuts the inner walls of the second flange 24 and the first flange 23, respectively. This effectively increases the contact area between the end cap 30 and the inner wall of the through-hole 21, effectively sealing the opening of the through-hole 21 and reducing potential leak paths. This design not only improves sealing performance but also enhances the stability and reliability of the connection. Compared to traditional sealing ring designs, the present invention utilizes the backing plate 20 to position and install the end cap 30. Due to the various mating features between the backing plate 20 and the end cap 30, proper installation can be intuitively verified during installation, reducing the possibility of missing parts. Furthermore, eliminating the need for a sealing ring makes installation faster and more convenient, reducing the potential for human error while ensuring the sound column's sealing performance.

[0036] Furthermore, a pressure balancing valve 32 may be installed inside the end cover 30 corresponding to the plug-in ring 31. A breathable membrane (not shown) is installed inside the pressure balancing valve 32 to balance the internal and external air pressures while taking waterproofing into consideration.

[0037] A plurality of alignment posts 33 are connected at intervals on a side of the end cover 30 facing the backing plate 20 and corresponding to the plug ring 31 . The alignment posts 33 correspond one-to-one with the alignment holes 25 to ensure assembly accuracy.

[0038] In this embodiment, a plurality of second through holes 34 are provided on the end cover 30 at intervals around the plug-in ring 31. The second through holes 34 correspond to the first through holes 26 one-to-one. The end cover 30, the backing plate 20 and the sound column box 10 are assembled by passing screws through the second through holes 34 and the first through holes 26 and then connecting them.

[0039] The above-mentioned sound column structure has a simple structure and is easy to assemble. The backing plate 20 is used to position and install the end cover 30. During installation, you can intuitively feel whether the backing plate 20 and the end cover 30 have been installed correctly, thereby reducing the possibility of missing installation. At the same time, the sealing ring is omitted, making the installation process faster and more convenient, reducing the possibility of human error, and ensuring the sealing performance of the sound column.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
