Description

Technical Field

[0001] This utility model relates to the field of monitoring headphone technology, specifically to a monitoring headphone with replaceable ear covers by the user. Background Technology

[0002] In the field of monitoring headphones, traditional headphones mostly use a one-piece injection molding or screw-fixed structure for the ear cover, which has the following technical defects: 1. Inconvenient disassembly and assembly: The ear cover and ear shell cannot be separated or require professional tools for disassembly. When the ear cover is worn or dirty due to long-term use, users cannot disassemble and clean it alone, which can easily breed bacteria and affect hygiene. This is especially true for professional teams that frequently share headphones, where hygiene issues are more prominent. 2. High maintenance costs: If the ear cap is damaged, the entire earphone shell needs to be replaced, as the ear cap cannot be replaced separately, which increases the user's maintenance costs; 3. Limited appearance: Traditional headphones have a fixed ear cover design, making it impossible for users to change the appearance of the ear covers according to usage scenarios or personal preferences, thus failing to meet personalized needs; 4. Poor sealing performance: Although some headphones attempt to design detachable ear covers, they do not have an effective sealing structure. Dust and liquid can easily enter the inside of the headphones, affecting the lifespan of core components such as speakers and circuits.

[0003] To address the aforementioned technical issues, while some existing headphones use snap-on ear covers, these snap-on structures are mostly exposed, making them prone to accidental detachment. Furthermore, they lack convenient unlocking mechanisms, requiring forced prying during disassembly, which can easily damage the snap-on mechanism or the ear shell. Consequently, they fail to balance stability and ease of assembly / disassembly.

[0004] Therefore, the existing disassembly structure of monitoring headphones has the technical problem of low reliability. It is evident that how to improve the reliability of the disassembly structure of monitoring headphones is a problem that needs to be solved in this field. Utility Model Content

[0005] To address the technical problem of unreliability in the disassembly structure of existing monitoring headphones, the purpose of this utility model is to provide a detachable monitoring headphone. This headphone is structurally stable, easy to assemble and disassemble, and features both sealing and personalization functions, allowing users to replace the ear covers themselves. It solves the problems of non-removable ear covers, high maintenance costs, and monotonous appearance of traditional headphones, effectively overcoming the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a detachable monitoring earphone, including an ear cover assembly, an ear shell assembly, a snap fastener assembly, and a switch button assembly. The snap fastener assembly is correspondingly disposed on the ear cover assembly and the ear shell assembly, and the ear cover assembly and the ear shell assembly are initially fixed by the corresponding snap fastener assembly. The switch button assembly is correspondingly disposed inside the ear shell assembly and on the ear cover assembly, and the connection and disconnection with the ear cover assembly are realized by the back-and-forth extension and retraction of the switch button assembly relative to the ear cover assembly.

[0007] Furthermore, the buckle assembly includes several protruding buckles and several slots. The several protruding buckles are symmetrically distributed on the outside of the ear cover assembly and are disposed on the ear cover assembly. The several slots are symmetrically disposed on the inside of the ear shell assembly, corresponding to the positions of the several protruding buckles. Through the buckling structure of the protruding buckles and the slots, the ear cover assembly and the ear shell assembly are initially fixed.

[0008] Furthermore, the ear shell assembly has an internal cavity for setting the switch button assembly.

[0009] Furthermore, the switch button assembly includes an operating hole, a hidden button, a reset spring, and a limit switch. The operating hole is located on the top of the ear shell assembly and penetrates the internal cavity of the ear shell assembly, corresponding to the position of the hidden button. One end of the hidden button has a guide surface that corresponds to the operating hole, and the other end is connected to the limit switch. The limit switch is elastically set in the internal cavity of the ear shell assembly by the reset spring. One end of the limit switch has a beveled guide surface, and the ear cover assembly has a matching beveled contact surface at the corresponding position. When assembling the ear cover assembly, the ear cover assembly presses against the limit switch through the inclined guide surface, which compresses the return spring until the ear cover assembly structure is completely inserted into the ear shell assembly. The return spring then resets and pushes the limit switch to lock the inclined contact surface on the ear cover assembly structure, thus achieving automatic locking of the ear cover assembly. When it is necessary to disassemble the ear cover assembly, insert a cylindrical tool into the operating hole and press down on the hidden button. The hidden button will compress the limit switch and retract, releasing the restriction on the ear cover assembly and completing the disassembly of the ear cover assembly.

[0010] Furthermore, an annular groove is formed on the edge of the ear cover assembly, and an annular sealing strip is embedded in the groove. When the ear cover assembly and the ear shell assembly are assembled in place, the annular sealing strip is tightly attached to the surface of the ear shell assembly.

[0011] Furthermore, the ear cover assembly has a positioning protrusion inside, and the ear shell assembly has a corresponding positioning hole on its inner side. When the ear cover assembly and the ear shell assembly are assembled, the positioning protrusion engages with the positioning hole on the inner side of the ear shell.

[0012] Furthermore, the outer side of the ear cover assembly is provided with a detachable decorative panel, which is connected to the ear cover assembly by a snap-fit ​​mechanism.

[0013] The detachable monitoring headphones provided by this utility model have a dual structure formed by the organic combination of C-shaped buckles and hidden switches, which makes the headphones easy to disassemble. Users can remove the ear covers without professional tools, using only common cylindrical tools. The headphones automatically lock during assembly, making the operation simple and efficient, and solving the problem of difficult ear cover disassembly and assembly in traditional headphones.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] Existing monitoring headphones have unreliable disassembly structures. To address this issue, this invention provides a detachable monitoring headphone with a dual structure design of "C-shaped buckle + hidden switch". Users can remove the ear cover without professional tools, using only common cylindrical tools. The headphone automatically locks during assembly, making it simple and efficient, thus solving the problem of difficult ear cover disassembly and assembly in traditional headphones.

[0019] See Figures 1-2 The detachable monitoring headphones provided by this utility model include an ear cover assembly 2, a snap-fit ​​assembly, an ear shell assembly 5, and a switch button assembly. The snap-fit ​​assembly is correspondingly disposed on the ear cover assembly 2 and the ear shell assembly 5, achieving initial fixation of the ear cover assembly 2 and the ear shell assembly 5 through their alignment. The switch button assembly is correspondingly disposed on the ear shell assembly 5 and the ear cover assembly 2, enabling the connection and detachment of the ear cover assembly 2 and the ear shell assembly 5 through the extension and retraction of the switch button assembly relative to the ear cover assembly 2.

[0020] The ear cover assembly 2 has an annular groove on its edge, and an annular sealing strip 3 is embedded in the groove. When the ear cover assembly 2 and the ear shell assembly 5 are assembled, the annular sealing strip 3 fits tightly against the surface of the ear shell assembly 5 to form a dustproof and waterproof sealing structure, which has the functions of dustproof, waterproof and buffer, preventing the ear cover assembly 2 and the ear shell assembly 5 from colliding and producing abnormal noise during assembly.

[0021] The ear shell assembly 5 has an internal cavity for setting a switch button assembly. This switch button assembly cooperates with the ear cover assembly 2 to realize a detachable connection structure between the ear shell assembly 2 and the ear cover assembly 5.

[0022] The snap-fit ​​assembly is used to initially fix the ear cover assembly 2 and the ear shell assembly 5. It includes several protruding snaps 41 and several slots 42. The protruding snaps 41 are symmetrically distributed on the outside of the ear cover assembly and are disposed on the ear cover assembly 2. The slots 42 are symmetrically disposed on the inside of the ear shell assembly 5, corresponding to the positions of the protruding snaps 41. The ear cover assembly 2 and the ear shell assembly 5 are initially fixed through the snap-fit ​​structure of the protruding snaps 41 and the slots 42.

[0023] Specifically, in this preferred embodiment, the ear cover assembly 2 is generally elliptical, and preferably has 3-4 protruding C-shaped buckle structures evenly distributed along the circumference on the inner side. The C-shaped buckle structure is easy to disassemble and has high stability, which can further improve the reliability of the detachable structure.

[0024] Meanwhile, the uniform spacing between the multiple C-shaped buckle structures ensures balanced force distribution on the ear covers.

[0025] Secondly, the C-type buckle structure is preferably made of high-strength synthetic plastic, which has good elasticity and wear resistance, avoiding buckle breakage due to long-term disassembly and assembly; Similarly, the outer side of the ear shell assembly 5 has a recessed C-shaped groove corresponding to the C-shaped buckle of the ear cover assembly 2. The depth and curvature of the C-shaped groove are perfectly matched with the C-shaped buckle to ensure that there is no looseness after locking.

[0026] In addition, to ensure the reliability of assembly, a positioning protrusion can be provided inside the ear cover assembly 2, and a corresponding positioning hole is provided on the inner side of the ear shell assembly 5. When the ear cover assembly 2 is assembled, the positioning protrusion cooperates with the positioning hole on the inner side of the ear shell assembly 5 to ensure that the C-type buckle and the C-type slot are precisely aligned, thereby improving assembly efficiency.

[0027] Furthermore, the switch button assembly is used to realize the detachable connection between the ear cover assembly 2 and the ear shell assembly 5, and includes an operation hole 61, a hidden button 62, a reset spring 63, and a limit switch 64.

[0028] The operation hole 61 is located on the top of the ear shell assembly 5 and passes through the internal cavity of the ear shell assembly 5, corresponding to the position of the hidden button.

[0029] The internal cavity is connected to the operation hole 61 on the side wall of the ear shell assembly 5, which is compatible with common cylindrical tools (such as SIM card ejector pins, pen tips, etc.) to facilitate users to obtain operation tools.

[0030] The hidden button 62 has a guide surface at one end that corresponds to the operation hole 61, and the other end is connected to the limit switch 64. The limit switch 64 is elastically set in the inner cavity of the ear shell by the reset spring 63. One end of the limit switch 64 has a sloping guide surface, and the ear cover assembly 2 has a matching sloping contact surface at the corresponding position.

[0031] When assembling the ear cover assembly 2, the ear cover assembly 2 presses the limit switch through the inclined guide surface, which compresses the return spring 63 until the ear cover structure is completely inserted into the ear shell assembly 5. The return spring 63 then resets and pushes the limit switch 64 to lock the inclined contact surface on the ear cover structure, thereby achieving automatic locking of the ear cover assembly 2 and forming a double fixation to prevent the ear cover assembly 2 from accidentally falling off.

[0032] When it is necessary to remove the ear cover, insert a cylindrical tool into the operating hole 61 and press down on the hidden button 62. The hidden button 62 compresses the limit switch 64 and retracts, releasing the restriction on the ear cover assembly 2. At the same time, push the ear cover assembly 2 upward to separate the ear cover assembly 2 from the ear shell assembly 5, thus completing the removal of the ear cover assembly 2. The entire process requires no special tools and is convenient and quick to operate.

[0033] Finally, this utility model has a detachable decorative panel 1 on the outside of the ear cover assembly 2. The decorative panel 1 is connected to the ear cover assembly 2 by a snap-fit ​​method. The decorative panel 1 can be printed with different patterns and logos, and adopts a lightweight design to avoid increasing the overall weight of the headphones and affecting the wearing experience.

[0034] As an example, the decorative panel 1 has several connecting protrusions symmetrically arranged around its edge, and the ear cover assembly 2 has several connecting grooves. The decorative panel 1 and the ear cover assembly 2 are connected by a snap-fit ​​method in which the connecting protrusions and connecting grooves cooperate. Users can flexibly match according to the usage scenario (such as stage performance, daily commute) and personal preferences to meet personalized needs. The following example illustrates the assembly process of a detachable monitoring headphone constructed using the above method in a specific application: When assembly is required: Step 1: Align the positioning protrusion on the inside of the ear cover 2 with the positioning hole of the ear shell 5, and gently press the ear cover 2 to make the ear cover 2 and the ear shell 5 fit tightly together. Step 2: Gently push the ear cover 2 downwards to fully align the ear cover 2 with the ear shell 5. The limit switch 64 will automatically pop out and firmly fix the ear cover 2 onto the ear shell.

[0035] When disassembly is required: Step 1: Use a cylindrical tool (such as a SIM card ejector tool) to insert into the operation hole 61 on the ear shell and gently press down on the hidden button 62; Step 2: While holding the pressing position, push the ear cover 2 upward to separate the C-shaped buckle 41 from the C-shaped slot 42, thus completing the removal of the ear cover 2; Step 3: The disassembled ear cover 2 can be cleaned and disinfected, or a new ear cover 2 can be replaced and the above assembly steps can be repeated.

[0036] The detachable monitoring headphones provided in this solution have the following advantages over existing solutions when used: Easy to disassemble and assemble: The dual structure formed by the organic combination of C-shaped buckle and hidden switch allows users to disassemble the ear cover without professional tools, using only common cylindrical tools. It automatically locks during assembly, making the operation simple and efficient, solving the problem of difficult disassembly and assembly of traditional headphone ear covers. Hygiene features: The earcups can be removed for cleaning and disinfection, and the sealing strips effectively prevent dust and liquid from entering the earphone, reducing bacterial growth. This makes it especially suitable for professional scenarios where earphones are shared, ensuring user hygiene. Maintenance cost-effectiveness: When the ear caps are worn or damaged, users only need to replace the ear cap parts, instead of replacing the entire headset, which greatly reduces maintenance costs and extends the overall lifespan of the headset; Personalized appearance: It supports changing the ear covers and decorative panels with different materials, colors and patterns, allowing users to flexibly match according to usage scenarios (such as stage performances, daily commutes) and personal preferences to meet personalized needs; Structural stability: The evenly distributed C-shaped buckles ensure balanced force, and the concealed switch provides double fixation. Combined with the buffering effect of the sealing strip, it effectively prevents the ear cap from accidentally falling off, loosening after assembly, or producing abnormal noise, thus improving the reliability of the headphones.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
