[0020] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0021] Embodiment 1: refer to Figures 1-4 As shown in the accompanying drawings, the present application provides a technical scheme: a replaceable ear shell protective shell, comprising a headset body 1 matched with the ear shell protective shell, the ear shell 11 on the headset body 1 is provided with a detachable ear shell protective shell 2, the edge of the ear shell protective shell 2 is provided with an inwardly extending buckling flange 21, the outer peripheral wall of the ear shell 11 is provided with an annular step 111 matched with the buckling flange 21, the buckling flange 21 and the annular step 111 are matched by clamping, so that the ear shell protective shell 2 is assembled to the ear shell 11, the inner side surface profile of the ear shell protective shell 2 is completely matched with the outer side surface profile of the ear shell 11, forming an over-molded protective structure.
[0022] On the basis of the headset body 1, the ear shell protective shell 2 which can be quickly assembled and disassembled is added, the ear shell 11 on the headset body 1 is further protected by the ear shell protective shell 2, so as to prevent the surface of the ear shell 11 from being scratched and affecting the appearance and use; when the headset body 1 accidentally falls, the ear shell 11 will be damaged, so that the electronic module and other components in the earphone are exposed, and the whole headset body 1 is scrapped; by adding the ear shell protective shell 2, when the headset body 1 accidentally falls, the ear shell protective shell 2 protects the ear shell 11, prevents the surface of the ear shell 11 from being damaged or scratched and affects the appearance and use, only the ear shell protective shell 2 needs to be replaced, and the service life of the headset body 1 is improved. At the same time, consumers can change the ear shell protective shell of different colors or patterns according to the use scene.
[0023] Refer to Figures 2-3 As shown in the accompanying drawings, the buckling flange 21 is a continuous annular protrusion or a plurality of protrusions distributed at intervals. Two design schemes of the buckling flange 21 are provided to meet different structural requirements, the continuous annular protrusion provides full circumferential rigid support, the plurality of protrusions distributed at intervals appropriately reduce the weight of the ear shell protective shell 2 while ensuring the strength of the rigid support, and when the ear shell protective shell 2 is disassembled, the disassembly gap can be quickly found.
[0024] Refer to Figure 4As shown, a resilient pad 3 is arranged between the inner side of the ear shell protective shell 2 and the outer side of the ear shell 11, the thickness of the resilient pad 3 is 0.2-0.5mm, and the material of the resilient pad 3 is rubber. The resilient pad 3 is arranged on the inner side of the ear shell protective shell 2. By adding the resilient pad 3, the impact energy generated when the earphone falls is absorbed, and the resonance between the ear shell protective shell 2 and the ear shell 11 is reduced.
[0025] The ear shell protective shell 2 is made of plastic integrated molding or new aerogel material. The aerogel material has better buffering performance and heat insulation performance, which can further improve the protection effect of the earphone while reducing the weight of the ear shell protective shell.
[0026] The ear shell protective shell replacement operation process is as follows: the finger presses the edge of the ear shell protective shell 2, the thumb nail or a pry bar (non-metal) is inserted into the disassembly gap, and the pry bar is lightly prised outward along the tangent direction. The first magnet 41 and the second magnet 42 of the magnetic attraction assembly are gradually separated by continuously applying force in the disengagement direction after the protective shell is partially disengaged. Then the new ear shell protective shell 2 is aligned to the ear shell 11 and assembled together, and the ear shell protective shell replacement step is completed.
[0027] Embodiment 2: see Figures 4-5 As shown, another kind of ear shell protective shell which can be quickly replaced is provided in the embodiment, and the embodiment 2 is basically the same as the embodiment 1, and the difference lies in that a magnetic attraction assembly is further arranged between the ear shell protective shell 2 and the ear shell 11. The magnetic attraction assembly includes a first magnet 41 embedded in the ear shell protective shell 2 and a second magnet 42 embedded in the ear shell 11, and the polarities of the first magnet 41 and the second magnet 42 are oppositely arranged. The snap flange 21 of the ear shell protective shell 2 and the magnetic attraction assembly jointly form a double fixing structure. The magnetic attraction force and the mechanical clamping cooperate with each other, the anti-pulling force is improved, the connection reliability is enhanced, the magnetic attraction force is limited in the range of 2-5N, which ensures the stability in daily use and avoids the need for excessive force when disassembling.
[0028] The ear shell protective shell replacement operation process is as follows: the finger presses the edge of the ear shell protective shell 2, the thumb nail or a pry bar (non-metal) is inserted into the disassembly gap, and the pry bar is lightly prised outward along the tangent direction. The first magnet 41 and the second magnet 42 of the magnetic attraction assembly are gradually separated by continuously applying force in the disengagement direction after the protective shell is partially disengaged. Then the new ear shell protective shell 2 is aligned to the ear shell 11 and assembled together, and the ear shell protective shell replacement step is completed.
