Earphone fixing assembly, earphone coating jig and earphone coating jig set

Abstract

Earphone fixing assembly, earphone coating jig and earphone coating jig set, wherein the earphone fixing assembly comprises a fixing block with a fixing cavity inside, and an elastic body assembled in the fixing cavity, the elastic body has an elastic cavity inside, and the surface of the fixing block exposes the elastic cavity. By inserting the head of the earphone directly into the elastic cavity of the elastic body for fixation, the earphone can be kept in an upright state, avoiding contact between the surface of the earphone shell and the fixing block, ensuring that the earphone shell is coated all around, thereby reducing the uneven film lines on the surface of the earphone shell. The head of the earphone will be sleeved with earbuds later, so even if the head of the earphone cannot be coated, it will not affect the overall external appearance after the earbuds are sleeved. In addition, since the elastic body will not damage the earphone shell, when inserting the head of the earphone into the elastic body, there is no need to pay special attention to the force, thereby improving the operation efficiency.

Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to an earphone fixing component, an earphone coating fixture, and an earphone coating fixture assembly. Background Technology

[0002] With the development of electronic technology, electronic devices such as mobile phones and headphones have emerged to meet users' needs and improve their quality of life. Headphones, originally used for telephones and radios, are now widely used in mobile phones, portable music players, radios, and audio players due to the popularity of portable electronic devices.

[0003] To improve the waterproof rating of headphones, vacuum coating is usually required to enhance their waterproof performance. Vacuum coating involves placing the substrate in a vacuum chamber, heating and evaporating the hydrophobic agent to be coated under vacuum conditions, and then rotating the object to be coated in the vacuum chamber. The film material is deposited on the surface of the object, which acts as a barrier against water vapor, rainwater, etc.

[0004] In existing technologies, conventional fixtures used for headphone coating result in some headphone shells not being coated because the headphones are placed directly on the fixture. This leads to uneven coating textures and colors on the product surface (i.e., color difference in the industry). Furthermore, placing the headphones onto the fixture requires extreme care to avoid damaging the shell, which further impacts operational efficiency. Summary of the Invention

[0005] The problem solved by this invention is to provide an earphone fixing component, an earphone coating fixture, and an earphone coating fixture assembly, which can reduce the presence of various uneven coating textures and colors on the earphone shell surface and improve operational efficiency.

[0011] Optionally, the material of the fixing block includes: plastic.

[0012] Accordingly, the present invention also provides an earphone coating fixture, comprising: an earphone partition; and a plurality of earphone fixing components assembled within the earphone partition, wherein the earphone fixing components are as described above.

[0013] Optionally, the headphone partition has several limiting grooves, and the headphone fixing assembly is fixed in the limiting grooves.

[0014] Optionally, it further includes: a carrier plate fixedly connected to the headphone partition, the headphone partition being located between the headphone fixing assembly and the carrier plate, and the carrier plate and the headphone partition having a first gap dimension in the vertical direction.

[0015] Optionally, it further includes: a plurality of first spacers, each of the first spacers being fixed between the headphone partition and the carrier plate, such that the headphone partition and the carrier plate have the first spacing dimension in the vertical direction.

[0016] Optionally, the first interval size is 5mm to 10mm.

[0017] Optionally, the material of the carrier disk includes: plastic.

[0018] Accordingly, the present invention also provides an earphone coating fixture assembly, comprising: a plurality of earphone coating fixtures that are stacked and fixedly connected to each other, each of the earphone coating fixtures as described above, and adjacent earphone coating fixtures having a second spacing dimension in the vertical direction.

[0019] Optionally, the headphone coating fixture includes a first surface and a second surface facing each other; the headphone coating fixture assembly further includes: a plurality of second spacers fixedly connected to the first surface of the headphone coating fixture; and a third spacer fixedly connected to the second surface of the headphone coating fixture.

[0020] Optionally, the second spacer and the third spacer of the adjacent headphone coating fixtures are connected such that the adjacent headphone coating fixtures have the second spacer dimension in the vertical direction.

[0021] Optionally, the second interval dimension is 10mm to 45mm.

[0022] Optionally, it also includes: an upper cover plate fixedly connected to the headphone coating fixture located at the top, and the upper cover plate and the headphone coating fixture located at the top have a third gap dimension in the vertical direction.

[0023] Optionally, it also includes a plurality of fourth spacer posts fixedly connected to the upper cover plate.

[0024] Optionally, the fourth spacer of the upper cover plate is connected to the second spacer of the headphone coating fixture located at the top, such that there is a third gap dimension in the vertical direction between the upper cover plate and the headphone coating fixture located at the top.

[0025] Optionally, the third interval dimension is 15mm to 45mm.

[0026] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0027] The earphone fixing assembly of this invention fixes the earphone head directly into the elastic cavity of the elastomer, keeping the earphone upright and preventing contact between the earphone shell surface and the fixing block. This ensures the earphone shell can be coated from all angles, reducing uneven coating textures and colors on the shell surface. Since ear tips will be fitted onto the earphone head later, even if the earphone head cannot be coated, the overall appearance will not be affected after the ear tips are installed. Furthermore, because the elastomer does not damage the earphone shell, no special force is required when inserting the earphone head, thus improving operational efficiency.

[0028] Furthermore, the fixing cavity includes: a first cavity portion and a second cavity portion communicating with the first cavity portion. The first cavity portion has a first diameter, and the second cavity portion has a second diameter, which is smaller than the first diameter. The surface of the fixing block exposes the second cavity portion. The elastic body includes: a first elastic portion adapted to the first cavity portion and a second elastic portion adapted to the second cavity portion. The second elastic portion is fixedly connected to the first elastic portion. Because the second diameter of the second cavity portion is smaller than the first diameter of the first cavity portion, and the elastic body has a large deformation capacity, the elastic body can be fitted into the fixing cavity. Specifically, the first elastic portion of the elastic body is assembled into the first cavity portion of the fixing cavity, and the second elastic portion of the elastic body is assembled into the second cavity portion of the fixing cavity. Utilizing the characteristic that the second diameter of the second cavity portion is smaller than the first diameter of the first cavity portion, after the elastic body is fitted into the fixing cavity, the elastic body will be confined within the fixing cavity and will not fall out. If the head of the earphone requires a larger elastic cavity to accommodate and secure it, the elastic body can be manually pulled out of the cavity to allow for replacement with a larger elastic body, thus accommodating different earphone models. In this embodiment, the design of the elastic body being snapped into the cavity eliminates the need for additional components to secure the elastic body and the cavity, facilitating the replacement of the elastic body.

[0029] By inserting the elastomer into the fixing cavity, the elastomer can be easily replaced to accommodate different models of headphones.

[0030] Furthermore, the fixing block is made of plastic. Plastic is a low-cost material and is easy to clean.

[0031] Furthermore, the elastomer is made of silicone. Silicone not only allows for significant deformation but is also soft and will not damage the headphone's head.

[0032] The headphone coating fixture of the present invention includes: a headphone partition; and a plurality of headphone fixing components assembled within the headphone partition. The headphone partition can simultaneously accommodate multiple headphone fixing components, thus improving the efficiency of headphone coating.

[0033] Furthermore, the headphone partition has several limiting grooves, and the headphone fixing assembly is fixed in the limiting grooves. The headphone fixing assembly is placed in the limiting grooves and then fixed to the headphone partition using screws. The optimal arrangement of the limiting grooves pre-cut in the headphone partition facilitates subsequent placement and arrangement.

[0034] Furthermore, it also includes: a carrier tray fixedly connected to the headphone partition, the headphone partition being located between the headphone fixing assembly and the carrier tray, and the carrier tray and the headphone partition having a first gap dimension in the vertical direction. The carrier tray enhances the stability of the headphone partition after several headphone fixing assemblies are placed on it.

[0035] Furthermore, the carrier tray is made of plastic. Plastic is a low-cost material and is easy to clean.

[0036] The headphone coating fixture assembly of the present invention includes: a plurality of overlapping and fixedly connected headphone coating fixtures, with a second gap in the vertical direction between adjacent headphone coating fixtures. The headphone coating fixture assembly can simultaneously accommodate multiple headphone fixing components, thus improving the efficiency of headphone coating. Attached Figure Description

[0042] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Typical embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0045] Figure 1 This is an exploded structural diagram of the headphone fixing assembly and the headphone in an embodiment of the present invention; Figure 2 This is a cross-sectional structural diagram of the headphone fixing component and the assembled headphone in an embodiment of the present invention.

[0046] Please refer to Figure 1 and Figure 2 An earphone fixing assembly 1 includes: a fixing block 10 having a fixing cavity 101; an elastic body 11 assembled in the fixing cavity 101 having an elastic cavity 111, and the surface of the fixing block 10 exposing the elastic cavity 111.

[0047] In this embodiment, the earphone head is fixed by directly inserting it into the elastic cavity 111 of the elastic body 11, allowing the earphone to remain upright and preventing contact between the earphone shell surface and the fixing block 10. This ensures that the earphone shell can be coated from all angles, thereby reducing uneven film textures and colors on the earphone shell surface. Since ear tips will be fitted onto the earphone head later, even if the earphone head cannot be coated, it will not affect the overall appearance after the ear tips are fitted. Furthermore, since the elastic body 11 does not damage the earphone shell, no special force is required when inserting the earphone head into the elastic body 11, thus improving operational efficiency.

[0048] Please continue to refer to this. Figure 2 In this embodiment, the fixing cavity 101 includes: a first cavity portion 101a and a second cavity portion 101b communicating with the first cavity portion 101a. The first cavity portion 101a has a first diameter, and the second cavity portion 101b has a second diameter, which is smaller than the first diameter. The surface of the fixing block 10 exposes the second cavity portion 101b.

[0049] Please continue to refer to this. Figure 2 In this embodiment, the elastic body 11 includes a first elastic part 112 adapted to the first cavity part 101a and a second elastic part 113 adapted to the second cavity part 101b, wherein the second elastic part 113 is fixedly connected to the first elastic part 112.

[0050] Because the second diameter of the second cavity portion 101b is smaller than the first diameter of the first cavity portion 101a, and the elastic body 11 has a large deformation capacity, the elastic body 11 can be secured within the fixed cavity 101. Specifically, the first elastic portion 112 of the elastic body 11 is assembled into the first cavity portion 101a of the fixed cavity 101, and the second elastic portion 113 of the elastic body 11 is assembled into the second cavity portion 101b of the fixed cavity 101. Utilizing the characteristic that the second diameter of the second cavity portion 101b is smaller than the first diameter of the first cavity portion 101a, after the elastic body 11 is secured within the fixed cavity 101, it will be confined within the fixed cavity 101 and will not fall out.

[0051] If the head of the earphone requires a larger elastic cavity 111 of the elastic body 11 to accommodate and fix it, the elastic body 11 can be pulled out from the fixing cavity 101 by applying force manually, and a larger elastic body 11 can be replaced to meet the fixing requirements of different models of earphones.

[0052] In this embodiment, by designing the elastomer 11 to be snapped into the fixing cavity 101, no additional parts are needed to fix the elastomer 11 and the fixing cavity 101, making it easy to replace the elastomer 11.

[0053] In this embodiment, the elastomer 11 is made of silicone. Silicone not only allows for significant deformation but is also soft and will not damage the headphone's head.

[0054] In this embodiment, the first elastic portion 112 and the second elastic portion 113 of the elastomer 11 are formed by integral injection molding.

[0055] In this embodiment, the fixing block 10 is made of plastic. Plastic is a low-cost material and is easy to clean.
