[0002] Currently, in order to reduce the noise output of the speaker, achieve complete audio presentation, and ensure the final audio effect received by the listener, acoustic dustproof components are installed inside the speaker during the process of transmitting audio information. Their biggest advantages are excellent mid-to-high frequency response and wide directivity, which enable sound to be transmitted effectively.

[0003] Existing acoustic dustproof components include a mesh layer. However, during the use of a loudspeaker, moisture can easily cause changes in the physical properties of the mesh layer, resulting in noise in the sound output by the loudspeaker.

[0004] Therefore, an acoustic dustproof component and support mechanism for loudspeakers are designed to solve the technical problem in the prior art where the mesh layer becomes damp, causing noise to be present in the loudspeaker's output sound.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0022] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0023] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0024] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0025] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0026] Research has revealed that existing acoustic dustproof components include a mesh layer, and during product use, vibration or moisture can easily alter the physical properties of this mesh layer, thus affecting the overall stability of the product.

[0027] Based on the above research, this disclosure provides an acoustic dustproof component and support mechanism for loudspeakers, which is provided with a protective layer. The foam layer in the protective layer absorbs moisture in humid environments, preventing the mesh layer from getting damp. Since the foam is a loose and porous material, it effectively reduces the vibration of the mesh, thereby increasing the overall stability of the product.

[0028] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the operator covers the foam layer 263, the third double-sided adhesive layer 23, the PET layer 25, the second double-sided adhesive layer 22, the mesh layer 262, and the first double-sided adhesive layer 21 layer by layer from bottom to top on the upper surface of the fourth double-sided adhesive layer 24. After the layer covering is completed, the operator uses a cutting tool to cut the covered whole into the size required for the product. The cut acoustic dustproof parts 2 are placed one by one on the upper surface of the backing paper 1, so that the bottom fourth double-sided adhesive layer 24 of the acoustic dustproof parts 2 is attached to the upper surface of the backing paper 1. Then, a protective film 260 is placed on the upper surface of the topmost layer of each acoustic dustproof part 2, namely the first double-sided adhesive layer 21. like Figure 1 As shown, four acoustic dustproof parts 2 are preferably grouped together. Each acoustic dustproof part 2 in each group is arranged in a square along the short side of the backing paper 1, and each group of acoustic dustproof parts 2 corresponds to a positioning port 10. The function of the positioning port 10 is to facilitate the workers in the next process to cut the backing paper 1 along the positioning port 10 to remove one group of acoustic dustproof parts 2 when the customer needs to use the acoustic dustproof parts. The function of the tear-off protrusion 261 on the side of the protective film 260 is that when the staff removes the individual acoustic dustproof component 2 from the backing paper 1 and places it in place, the protective film 260 can be removed along the tear-off protrusion 261. It should be noted that the foam layer 263 has a micropore array on its four walls with a pore size of 50μm and an open porosity of 30%. The central hollow of the mesh layer 262, the central hollow of the four double-sided adhesive layers (21, 22, 23, 24), and the strip hollow in the center of the PET layer form breathable channels.

[0032] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 utility model based on the specific circumstances.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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 a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0034] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0035] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
