Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to a type of headphones. Background Technology

[0002] As the demand for personalization in the consumer electronics market upgrades, headphones not only need to meet audio playback functions, but also become a fashion accessory for users to express their personal style and adapt to diverse scenarios (such as daily commuting, business office, and leisure entertainment). However, most headphones have fixed decorative covers, which users cannot change according to their personal preferences or clothing styles, thus lacking a way to express personalization. Although a small number of headphones offer replaceable decorative covers, their replacement mechanisms are complicated (such as using clips, screws, etc.), inconvenient to operate, and easy to damage the decorative covers, resulting in a poor user experience.

[0003] In existing technology, there is a magnetic decorative cover connection structure, which includes an earphone body, a light guide plate disposed on the outer side of the earphone body, and a decorative cover magnetically connected to the outer side of the light guide plate. A first magnet is disposed on the light guide plate, and a second magnet is disposed on the decorative cover. The decorative cover is magnetically connected to the light guide plate through the cooperation of the first magnet and the second magnet. With this structure, on the one hand, when the earphone is worn, if it shakes or is slightly impacted, the hard collision between the magnet and the plastic part of the earphone body can easily produce a "click" noise, which will destroy the immersive audio listening experience. On the other hand, during the long-term and frequent magnetic attraction and disassembly process, the magnet will cause continuous friction on the contact surface, resulting in scratches, whitening, or even wear and dents on the contact surface. This not only affects the appearance of the earphone, but also widens the gap due to wear on the contact surface, further weakening the magnetic attraction force, and eventually causing the decorative cover to loosen and the magnet to fall off, reducing the product's lifespan. Furthermore, there will be an installation gap between the decorative cover and the light guide plate, which will prevent the formation of a sealed cavity between the decorative cover and the light guide plate, which can easily affect the sound quality of the headphones.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a type of over-ear headphone. This headphone features a flexible film attached to the outer side of a light guide plate, and a first annular wall on the inner side of a decorative cover. The first annular wall presses against the outer side of the flexible film, creating a sealed cavity between the light guide plate and the decorative cover through the flexible film. The flexible film serves several purposes: firstly, it absorbs minor impacts and vibrations during daily use, preventing hard contact between the decorative cover and the light guide plate, effectively preventing scratches, wear, and abnormal noises; secondly, it blocks direct contact and collision between the second magnetic component and the light guide plate, further protecting the light guide plate; and thirdly, the flexible film deforms under pressure, filling the installation gap between the decorative cover and the light guide plate, making their connection tighter. This not only enhances the strength of the magnetic attraction but also forms a sealed cavity, improving acoustic airtightness to a certain extent, thereby improving the sound quality of the over-ear headphone.

[0020] First, it should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0021] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an earphone body 10, a light guide plate 20 disposed on the outer side of the earphone body 10, and a decorative cover 30 magnetically connected to the outer side of the light guide plate 20.

[0022] Two earphone bodies 10 are provided, and the two earphone bodies 10 are connected together by a headband 40. The earphone bodies 10 are existing mature technologies and will not be described in detail here.

[0023] The light guide plate 20 has a first magnetic attraction component 50 on its inner side, and the decorative cover 30 has a second magnetic attraction component 60 on its inner side that magnetically engages with the first magnetic attraction component 50. The decorative cover 30 is magnetically connected to the light guide plate 20 through the engagement of the first magnetic attraction component 50 and the second magnetic attraction component 60. A flexible film 70 is attached to the outer side of the light guide plate 20. The decorative cover 30 has a first annular wall 31 on its inner side, which presses against the outer side of the flexible film 70. A sealed cavity 80 is formed between the light guide plate 20 and the decorative cover 30 through the flexible film 70.

[0024] Specifically, see Figure 1 and Figure 4 As shown, the first magnetic attraction component 50 includes two first magnets 51 with opposite magnetic properties on their outer surfaces, and the second magnetic attraction component 60 includes two second magnets 61 with opposite magnetic properties on their inner surfaces that match the corresponding first magnets 51. The opposite magnetic properties mean that one is the S pole and the other is the N pole. The decorative cover 30 can only magnetically engage with the light guide plate 20 when the magnetic poles are aligned, which plays a foolproof role and ensures that the decorative cover 30 can be assembled correctly. Furthermore, the inner side of the light guide plate 20 is provided with a first mounting groove 201 for mounting the first magnet 51, and the first magnet 51 is fixed in the first mounting groove 201. The inner side of the decorative cover 30 is provided with a mounting post 301, which is flush with the first annular wall 31. The mounting post 301 is provided with a second mounting groove 302 for mounting the second magnet 61, and the second magnet 61 is fixed in the second mounting groove 302. The outer side of the earphone body 10 is provided with a third mounting groove 101, and the third mounting groove 101 has a through hole 102 connecting the inside of the earphone body 10 and the outside of the earphone body 10. The inner side of the light guide plate 20 is provided with a fourth mounting groove 202, and the fourth mounting groove 202 is located in the third mounting groove 101. A PCBA light-emitting module 90 is fixed in the fourth mounting groove 202, and the PCBA light-emitting module 90 covers the through hole 102. The outer side of the earphone body 10 is provided with a fifth mounting groove 103, and the first mounting groove 201 is located in the fifth mounting groove 103.

[0025] Preferably, a pad 100 is provided between the inner side of the second magnet 61 and the outer side of the flexible film 70. The pad is located in the second mounting groove 302. The pad 100 can be an EVA pad. The design of the EVA pad can further play a protective role. The flexible film 70 has a hollow groove 701 in the area surrounded by the first annular wall 31. The hollow groove 701 can play a role in venting, so that the flexible film 70 can be smoothly attached to the light guide plate 20. At the same time, the shape of the hollow groove 701 can be designed as needed, which can play a decorative role.

[0026] See Figure 5 As shown, the outer side of the light guide plate 20 is provided with a second annular wall 203. The flexible film 70 and the decorative cover 30 are both located within the area enclosed by the second annular wall 203. The arrangement of the second annular wall 203 facilitates the assembly and positioning of the flexible film 70 and the decorative cover 30.

[0027] In this embodiment, the decorative cover 30 is in the shape of an outwardly arched protrusion, the first magnet 51 and the second magnet 61 are both neodymium iron boron magnets, and the flexible film 70 is made of flexible PC material. Flexible PC material is an existing known material, and you can refer to the DB9 flame retardant film series of Hunan Dibo Optical Materials Co., Ltd.

[0028] The assembly process of this embodiment is described in detail below: Disassembly process: Users can use their fingers to hold the edge of the decorative cover 30 and apply slight force to overcome the magnetic force and remove it. The elasticity of the flexible film 70 in the middle helps the decorative cover 30 to be pushed away when the magnetic force weakens, making disassembly easier.

[0029] Installation process: The user aligns the new decorative cover 30 with the headphone body 10. Due to the foolproof design of the first magnetic component 50 and the second magnetic component 60, only one correct angle can make the decorative cover 30 fit completely with the headphone body 10. When the decorative cover 30 gets close to a certain distance, the magnetic force starts to work, automatically attracting the decorative cover 30 to the light guide plate 20 and making a clear "click" sound, providing feedback that the installation is in place. At the moment of final attraction, the flexible film 70 and the EVA pad are compressed. The elastic force generated by the compression and the magnetic force work together to form a connection that is both firm and flexible, eliminating assembly gaps and avoiding vibration and abnormal noise.

[0030] The key design feature of this utility model is: The main feature is that a flexible film is attached to the outer side of the light guide plate, and a first annular wall is provided on the inner side of the decorative cover. The first annular wall presses against the outer side of the flexible film, so that a sealed cavity is formed between the light guide plate and the decorative cover through the flexible film. The flexible film has two functions: firstly, it can absorb slight impacts and vibrations during daily use, avoiding hard contact between the decorative cover and the light guide plate, and effectively preventing scratches, wear, and abnormal noises; secondly, it blocks direct contact and collision between the second magnetic component and the light guide plate, further protecting the light guide plate; and thirdly, the flexible film deforms under pressure, which can fill the installation gap between the decorative cover and the light guide plate, making the two more tightly connected. This not only enhances the firmness of the magnetic attraction but also forms a sealed cavity, which can improve the acoustic airtightness to a certain extent, thereby improving the sound quality of the headphones.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
