[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0047] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0050] Please see Figures 1 to 13 This embodiment provides an earphone case, which includes a case body 1 and a case lid 2. The case body 1 is provided with a receiving slot 14 for accommodating wireless earphones 100. The case lid 2 can close or open the slot of the receiving slot 14, so that the user can store the wireless earphones 100 in the earphone case or take them out of the earphone case.

[0051] In addition, the box body 1 is also provided with a turntable 11, a stop 12 and a push rod 13. The stop 12 is rotatably connected to the turntable 11. The stop 12 is provided with a stop ear 121. The push rod 13 can push the stop 12 to rotate and make the stop ear 121 rotate and switch between the first working state and the second working state. The box cover 2 is provided with a locking block 21. The box cover 2 can be fastened to the top of the box body 1. In the first working state, the stop ear 121 stops the locking block 21 on the side away from the box body 1 to lock the box cover 2. In the second working state, the stop ear 121 releases the locking block 21 to unlock the box cover 2.

[0052] Therefore, when the lid 2 is placed on top of the body 1, the lid 2 seals the receiving groove 14. The stop 12 on the body 1 can be pushed and rotated by the push rod 13, and the ear 121 of the stop 12 is in the first working state. The ear 121 in the first working state can stop the locking block 21 on the lid 2 to lock the lid 2 and keep the lid 2 closed on the body 1, thereby preventing the lid 2 from being accidentally opened when the headphone case shakes, thus improving the user experience.

[0053] When the user needs to use the headphones, the push rod 13 pushes the stop 12 to rotate, and the ear cover 121 releases its block against the locking block 21, so that the case cover 2 can be opened and the headphones can be taken out from the receiving slot 14.

[0054] For example, in this embodiment, the lid 2 is rotatably connected to the body 1. Specifically, the body 1 and the lid 2 are rotatably connected by a pivot 15. A torsion spring 151 is sleeved on the pivot 15 and installed between the lid 2 and the body 1. The torsion spring 151 can drive the lid 2 to open after the lug 121 releases its obstruction of the locking block 21. That is, in this embodiment, when the lug 121 releases its obstruction of the locking block 21, the lid 2 can open automatically, thereby further improving the user experience.

[0055] Of course, in other alternative embodiments, the lid 2 may also be movably connected to the box body 1 in other ways, and this embodiment does not impose specific limitations on this.

[0056] Furthermore, in this embodiment, the box body 1 also includes a positioning structure, which is disposed between the stop 12 and the turntable 11. The positioning structure can position the stop 12 when the ear 121 is in the first working state and the second working state, so as to ensure that the box cover 2 can be stably held to close the box body 1, and that the box cover 2 can be normally restored to close the box body 1 in the future.

[0057] Specifically, the positioning structure includes a pin 111 located on the turntable 11, and a first slot 1221 and a second slot 1222 located on the stop member 12. The first slot 1221 and the second slot 1222 are arranged around the rotation axis of the stop member 12. The pin 111 can be selectively inserted into the first slot 1221 and the second slot 1222, that is, the pin 111 can be inserted into the first slot 1221 or the second slot 1222. Moreover, the pin 111 can be moved out of the first slot 1221 or the second slot 1222 when the push rod 13 pushes the stop member 12 to rotate.

[0058] When the pin 111 is inserted into the first slot 1221, the stop ear 121 is in a first working state, which allows the stop ear 121 to hold the locking block 21, thereby ensuring that the lid 2 can be securely held in place of the lid body 1. When the pin 111 is inserted into the second slot 1222, the stop ear 121 is in a second working state, ensuring that the stop ear 121 does not interfere with the locking block 21 rotating with the lid 2, so that the lid 2 can be properly restored to the lid body 1.

[0059] Of course, in other alternative embodiments, the stop 12 may be provided with a pin 111, and the turntable 11 may be provided with a first slot 1221 and a second slot 1222. This embodiment does not impose specific limitations on this.

[0060] Furthermore, the stop member 12 is provided with at least two lugs 121, which are evenly arranged around the rotation axis and can be rotated alternately to the stop position 3. When the lugs 121 are rotated to the stop position 3, they are in a first working state. Specifically, the stop member 12 consists of a body 123 and at least two lugs 121, wherein the body 123 is rotatably connected to the turntable 11, and the at least two lugs 121 surround the outer periphery of the body 123 and are evenly arranged around the rotation axis of the stop member 12.

[0061] The earphone case is provided with at least two positioning slot groups 122, which are evenly arranged around the rotation axis and correspond one-to-one with at least two ear shields 121. All positioning slot groups 122 include a first slot 1221 and a second slot 1222. Moreover, the first slot 1221 and the second slot 1222 are arranged at intervals along the rotation direction of the stop member 12.

[0062] It is worth noting that in this embodiment, the pin 111 is disposed on the turntable 11, the first slot 1221 and the second slot 1222 are disposed on the stop member 12, the stop member 12 can rotate, while the turntable 11 remains stationary. Thus, in this embodiment, along the rotation direction of the stop member 12, the first slot 1221 is located downstream of the second slot 1222.

[0063] Accordingly, in other alternative embodiments, if the pin 111 is disposed on the stop member 12 and the first slot 1221 and the second slot 1222 are disposed on the turntable 11, then the second slot 1222 is located downstream of the first slot 1221 along the rotation direction of the stop member 12.

[0064] Therefore, this embodiment is described using the example of a stop member 12 having four ear flaps 121 and an earphone case having four positioning groove groups 122. In this embodiment, the four ear flaps 121 rotate synchronously and can alternately rotate to the stop position 3.

[0065] Therefore, for any ear block 121, when the ear block 121 is in the stop position 3, the positioning groove group 122 corresponding to the ear block 121 is directly opposite the pin 111, and the slot is inserted into the first slot 1221 of the positioning groove group 122. At this time, the case cover 2 keeps the case body 1 closed. When it is necessary to open the earphone case, the push rod 13 pushes the stop member 12 to rotate and causes the ear block 121 to rotate at a first preset angle, thereby causing the slot to switch to the second slot 1222 inserted into the positioning groove group 122. At this time, the push rod 13 stops pushing the stop member 12 to rotate, the ear block 121 releases the stop on the locking block 21, and the case cover 2 can be opened. Moreover, along the rotation direction of the stop member 12, the next ear block 121 located upstream of the ear block 121 and adjacent to the ear block 121 has not rotated to the stop position 3.

[0066] After the lid 2 is closed again onto the top of the case 1, i.e., after the earphone case is closed again, the push rod 13 continues to push the stop 12 to rotate. The earbud 121 that was in the stop position 3 when the earphone case was closed last time rotates to the second preset angle. Along the rotation direction of the stop 12, the next earbud 121 located upstream of the earbud 121 and adjacent to the earbud 121 rotates to the stop position 3 and stops the locking block 21. Moreover, the positioning groove group 122 corresponding to the earbud 121 that was in the stop position 3 last time moves away from the pin 111, while the positioning groove group 122 corresponding to the earbud 121 that rotates to the stop position 3 this time takes over and faces the pin 111, and the pin 111 is inserted into the first slot 1221.

[0067] Therefore, in this embodiment, the four earplugs 121 can rotate to the stop position 3 in turn and switch from the first working state to the second working state in turn. Thus, after each time the headphone case is closed, the push rod 13 only needs to push the stop member 12 to rotate a small angle to restore the stop locking block 21, so that the case cover 2 keeps the case body 1 closed. That is, after each time the headphone case is closed, the stop member 12 can quickly restore the stop locking block 21.

[0068] Furthermore, the insertion end of the pin 111, the first slot 1221, and the second slot 1222 are all hemispherical. A first elastic element 9 is provided at the end of the pin 111 furthest from the first slot 1221 or the second slot 1222. That is, in this embodiment, the headphone case also includes a first elastic element 9, which is configured to drive the pin 111 to stop inserting into the first slot 1221 or the second slot 1222. Specifically, based on the above description, the pin 111 is disposed on the turntable 11. Correspondingly, the turntable 11 is provided with a mounting groove 112. The pin 111 is inserted into the mounting groove 112, and the insertion end of the pin 111 can extend out of the mounting groove 112 and into the first slot 1221 or the second slot 1222. Thus, the turntable 11 is sleeved on the outer periphery of the pin 111 through the mounting groove 112. The first elastic element 9 is a spring, and it is disposed between the pin 111 and the bottom of the mounting groove 112.

[0069] During the rotation of the stop member 12, the body 123 of the stop member 12 remains pressed against the pin 111, causing the pin 111 to retract into the mounting groove 112. At this time, the first elastic member 9 is compressed and deformed. When the pin 111 is aligned with the first slot 1221 or the second slot 1222, the first elastic member 9 returns to its original shape, so that the insertion end of the pin 111 extends out of the mounting groove 112 and into the first slot 1221 or the second slot 1222, thereby locking the position of the stop member 12.

[0070] When the push rod 13 pushes against the stop member 12, since the insertion end of the pin 111, the first slot 1221 and the second slot 1222 are all hemispherical, and the first elastic member 9 is installed in the mounting groove 112, the insertion end of the pin 111 can slide along the groove wall of the first slot 1221 or the second slot 1222. At the same time, the first elastic member 9 is compressed and deformed, so that the pin 111 gradually retracts into the mounting groove 112, thereby allowing the pin 111 to be moved out of the first slot 1221 or the second slot 1222.

[0071] Furthermore, combining Figure 4 and Figure 6 And see Figures 9 to 11 At least two stop ears 121 can alternately rotate from the stop position 3 to the transmission position 4. Based on the above description, for any stop ear 121 located in the stop position 3, after the stop member 12 rotates twice in succession by the first preset angle and the second preset angle respectively, the stop ear 121 will rotate to the transmission position 4. The push rod 13 can push against the stop ear 121 located in the transmission position 4 and drive the stop ear 121 located in the stop position 3 to rotate from the stop position 3 to the transmission position 4. Thus, when one of the at least two stop ears 121 is located in the stop position 3, the other stop ear 121 is located in the transmission position 4.

[0072] For example, in this embodiment, when one of the two adjacent lugs 121 rotates to the transmission position 4, the other rotates to the stop position 3.

[0073] That is, in this embodiment, the push rod 13 pushes against the stop ear 121 located at the transmission position 4, thereby driving the stop member 12 to rotate as a whole. During this process, all the stop ears 121 rotate synchronously.

[0074] Based on the above, in this embodiment, when the earphone case needs to be opened, the push rod 13 pushes against the ear block 121 located at the transmission position 4, thereby causing the stop member 12 to rotate. This causes the ear block 121 located at the stop position 3 to avoid the locking block 21, allowing the case cover 2 to open. At this time, the ear block 121 that has left the stop position 3 has not rotated to the transmission position 4, but is located between the stop position 3 and the transmission position 4. When the case cover 2 is closed again to the top of the case body 1, the push rod 13 continues to push against the same ear block 121, causing the stop member 12 to continue to rotate. This causes the ear block 121 originally located at the stop position 3 to rotate to the transmission position 4. At the same time, along the rotation direction of the stop member 12, the next ear block 121 located upstream of the ear block 121 rotates to the stop position 3 and replaces the stop locking block 21.

[0075] For example, in this embodiment, the push rod 13 can move forward along its axial direction and push against the stop ear 121, so that the pin 111 moves out of the first slot 1221 and moves into the second slot 1222 and the next first slot 1221 in sequence. That is, in this embodiment, the push rod 13 moves forward along its axial direction and pushes against the stop ear 121 located at the transmission position 4, thereby driving the stop member 12 to rotate. After the stop ear 121 located at the transmission position 4 rotates for the first time, the stop ear 121 located at the stop position 3 releases its stop on the locking block 21. At the same time, the pin 111 is inserted into the second slot 1222 of the positioning groove group 122 corresponding to the stop ear 121 that leaves the stop position 3, so that the box cover 2 can be opened and the box cover 2 can be closed again. When the lid 2 is closed again, the push rod 13 pushes against the stop ear 121 that has left the transmission position 4 and rotates for the second time, so that the stop ear 121 that was originally in the stop position 3 rotates to the transmission position 4, and the next stop ear 121 rotates to the stop position 3. At this time, the pin 111 is inserted into the next first slot 1221, so that the lid 2 keeps the lid on the box body 1.

[0076] Furthermore, in this embodiment, a push plate 131 is provided at one end of the push rod 13. The push plate 131 is slidably mounted on the push rod 13. The end of the push rod 13 away from the push plate 131 extends out of the housing 1 and is connected to a button 132. The push rod 13 pushes against the stop ear 121 through the push plate 131. The end of the push rod 13 extending out of the housing 1 forms a pressing end. The user can press the end of the push rod 13 extending out of the housing 1, thereby causing the push rod 13 to move in the positive direction along its axial direction, and then push the stop member 12 to rotate. Specifically, the push rod 13 can push against the stop ear 121 through the push plate 131 and cause the stop member 12 to rotate.

[0077] Understandably, when the user presses the push rod 13 and rotates the stop 12 until the pin 111 moves into the second slot 1222, the lid 2 opens automatically. When the user closes the lid 2 to close the box body 1 again, the user increases the pressing force applied to the push rod 13, and the pin 111 can move out of the second slot 1222. Then, the stop 12 continues to rotate. When the pin 111 moves into the next first slot 1221, the pin 111 can stop the stop 12. At this time, the user can feel the resistance transmitted by the push rod 13, thus knowing that the locking block 21 has been stopped again.

[0078] In summary, in this embodiment, the push rod 13 can move sequentially from the initial working position to the first working position and the second working position along its axial direction. During the process of the push rod 13 moving from the initial working position to the first working position, the push rod 13 pushes the stop member 12 to rotate, and causes the ear 121 located at the stop position 3 to leave the stop position 3. The pin 111 moves out of the first slot 1221 and into the second slot 1222. At this time, the locking block 21 is not stopped, and the box cover 2 can be opened. During the process of the push rod 13 moving from the first working position to the second working position, the push rod 13 continues to push the stop member 12 to rotate, and causes the ear 121 originally located at the stop position 3 to rotate to the transmission position 4. The pin 111 moves into the next first slot 1221. At this time, the next ear 121 rotates to the stop position 3 and stops the locking block 21 again, so that the box cover 2 keeps the box body 1 closed.

[0079] It is worth noting that after the push rod 13 moves to the second working position, in order for the push rod 13 to push the stop 12 to rotate again, so as to open and lock the box cover 2 in sequence, the push rod 13 needs to be reset to the initial working position.

[0080] Therefore, in combination Figure 4 and Figure 6 And see Figure 12 and Figure 13In this embodiment, the earphone case further includes a reset mechanism 5, which is configured to reset the push rod 13 after it pushes against the ear block 121 located at the transmission position 4 and rotates the ear block 121 located at the stop position 3 to the transmission position 4. Based on the above, the reset mechanism 5 is configured to move the push rod 13 in the opposite direction to reset it, so that the push rod 13 can push against the stop member 12 again to rotate, thereby opening and locking the case cover 2 in sequence.

[0081] Based on the above description, a push plate 131 is provided at one end of the push rod 13 inside the housing 1. The push rod 13 pushes against the stop ear 121 through the push plate 131. In this embodiment, the push plate 131 is slidably installed on the push rod 13.

[0082] The reset mechanism 5 includes a spring pin 51 and a guide member 52. The spring pin 51 is disposed on the push plate 131. The guide member 52 includes a first guide groove 521 and a second guide groove 522 arranged in parallel. That is, the guide member 52 has a first guide groove 521 and a second guide groove 522 arranged in parallel. Along the length direction of the push plate 131, the first guide groove 521 is disposed between the push rod 13 and the second guide groove 522. The first guide groove 521 and the second guide groove 522 are connected by a transition groove 523.

[0083] For example, in this embodiment, the push plate 131 is slidably mounted on the push rod 13 in a direction perpendicular to the axial direction of the push rod 13. The extension directions of the first guide groove 521 and the second guide groove 522 are both parallel to the axial direction of the push rod 13. Along the sliding direction of the push plate 131, the second guide groove 522 is disposed on the side of the first guide groove 521 away from the stop member 12, and the transition groove 523 is arc-shaped. Specifically, one end of the first guide groove 521 is provided with a first opening 5211, and one end of the second guide groove 522 is provided with a second opening 5221. The first opening 5211 and the second opening 5221 are disposed on the same side. The side of the first guide groove 521 away from the first opening 5211 and the side of the second guide groove 522 away from the second opening 5221 are connected by the transition groove 523. The transition groove 523 is arc-shaped and bends toward the side away from the first opening 5211 and the second opening 5221.

[0084] As described above, the spring pin 51 is slidably connected to the first guide groove 521, the transition groove 523, and the second guide groove 522. Specifically, the spring pin 51 can move into the first guide groove 521 and slide into the second guide groove 522 through the transition groove 523, so that the push plate 131 slides toward the side away from the stop member 12. Specifically, when the push rod 13 moves forward, the spring pin 51 can move into the first guide groove 521 through the first opening 5211. During the process of the push rod 13 moving to the second working position, the spring pin 51 moves into the first guide groove 521. Moreover, the spring pin 51 can subsequently move to the second guide groove 522 through the transition groove 523, so that the push plate 131 slides away from the stop member 12. Specifically, after the push rod 13 moves to the second working position, the user continues to press the push rod 13, so that the push rod 13 continues to move forward along its axial direction, so that the spring pin 51 slides along the transition groove 523. Under the guidance of the transition groove 523, the push plate 131 slides away from the stop member 12, so that the push plate 131 moves away from the stop member 12 along its sliding direction.

[0085] When the spring pin 51 moves into the second guide groove 522, the push rod 13 can move in the opposite direction and reset to the initial working position. During the reset process, since the push plate 131 moves away from the stop member 12 along its sliding direction, the stop ear 121 located at the transmission position 4 will not block the push rod 13 from resetting.

[0086] As described above, the reset mechanism 5 also includes a first reset member 6 and a second reset member 7. The first reset member 6 is configured to drive the push rod 13 to reset after the spring pin 51 moves into the second guide groove 522. Exemplarily, in this embodiment, the first reset member 6 is a second elastic member, which is a spring. A button 132 is provided at one end of the push rod 13 extending out of the housing 1. The first reset member 6 is sleeved on the push rod 13 and is disposed between the button 132 and the outer wall of the housing 1. When the user presses the push rod 13 to move the push rod 13 in the forward direction along its axial direction, the second elastic member is compressed and deformed. After the spring pin 51 moves into the second guide groove 522, the second elastic member recovers its deformation, thereby causing the push rod 13 to move in the reverse direction along its axial direction to reset.

[0087] As described above, the push rod 13 can continue to move from the second working position to the third working position along its axial direction. At this time, the spring pin 51 slides along the transition groove 523 to the middle part of the transition groove 523. Then, under the action of the second elastic element, the push rod 13 resets along its axial direction. At the same time, the spring pin 51 continues to slide along the transition groove 523 until it moves into the second guide groove 522.

[0088] It is understandable that during the process of push rod 13 pushing stop 12 to rotate via push plate 131, as stop 12 rotates, the stop ear 121 that abuts against push plate 131 will gradually move away from push plate 131. Thus, after push rod 13 moves from the first working position to the second working position and causes the next stop ear 121 to rotate to stop position 3, after push rod 13 drives the stop ear 121 originally located at stop position 3 to rotate to transmission position 4, push plate 131 releases its contact with stop 12. That is, after push rod 13 drives the stop ear 121 originally located at stop position 3 to rotate to transmission position 4, push plate 131 passes the stop ear 121 originally located at transmission position 4. After that, when push rod 13 moves to the third working position, stop 12 remains stationary.

[0089] Additionally, it can be understood that in this embodiment, when the user presses the push rod 13 to move it to the first working position, the lid 2 can be opened. At this time, the user releases the push rod 13, and the push rod 13 is directly reset to the initial working position under the action of the first reset member 6. Afterwards, when the user puts the lid 2 back on the top of the box body 1, the user presses the push rod 13 again, and the push rod 13 moves from the initial working position to the second working position. In this process, the push rod 13 first moves to the first working position and then continues to move directly to the second working position. During the process of the push rod 13 moving from the first working position to the second working position, the push rod 13 pushes against the stop member 12 and continues to rotate, so that the next stop ear 121 rotates to the stop position 3 and stops the locking block 21 again, thereby keeping the lid 2 closed on the box body 1.

[0090] It is worth noting that during the process of the push rod 13 moving in the reverse direction along its axis to reset, the spring pin 51 slides along the second guide groove 522. After the push rod 13 resets to the initial working position, the spring pin 51 moves out of the second guide groove 522 through the second opening 5221. Therefore, the second reset member 7 is configured to drive the push plate 131 to reset so that the spring pin 51 is aligned with the first guide groove 521 after the spring pin 51 moves out of the second guide groove 522, so that the spring pin 51 can move back into the first guide groove 521 after the push rod 13 moves forward again.

[0091] For example, in this embodiment, the second reset member 7 is a third elastic member, which is a spring. The push rod 13 is provided with a connecting post 133. The connecting post 133 and the spring pin 51 are arranged at intervals along the sliding direction of the push plate 131. The two ends of the second reset member 7 are respectively connected to the connecting post 133 and the spring pin 51. When the spring pin 51 slides along the transition groove 523 and the push plate 131 slides toward the side away from the stop member 12, the third elastic member undergoes elastic deformation. After the spring pin 51 moves out of the second guide groove 522, the third elastic member restores its deformation, thereby making the push plate 131 reset to align the spring pin 51 with the first guide groove 521.

[0092] Furthermore, based on the foregoing description, the spring pin 51 is slidably mounted on the push plate 131. Specifically, the spring pin 51 is slidably mounted on the push plate 131 along the extension direction of the rotation axis of the stop member 12. The bottom of the transition groove 523 is provided with a ramp 5231, which gradually rises from the side near the first guide groove 521 to the side near the second guide groove 522. Thus, when the spring pin 51 slides along the transition groove 523 from the side near the first guide groove 521 to the side near the second guide groove 522, it moves along the stop member 12... In the direction of the extension of the rotation axis, the spring pin 51 can be lifted, and a third reset member 8 is provided between the push plate 131 and the spring pin 51. That is, the reset mechanism 5 also includes a third reset member 8. The third reset member 8 is configured to drive the spring pin 51 to reset after the spring pin 51 crosses the ramp 5231. That is, the third reset member 8 can drive the spring pin 51 to fall after the spring pin 51 crosses the ramp 5231. At this time, the ramp 5231 can stop the spring pin 51, thereby preventing the spring pin 51 from returning to the first guide groove 521 through the transition groove 523.

[0093] For example, in this embodiment, when the push rod 13 moves in the positive direction along its axial direction to the third working position, the spring pin 51 crosses the ramp 5231.

[0094] Therefore, this embodiment can ensure that the spring pin 51 can be accurately moved into the second guide groove 522, thereby ensuring that the push rod 13 can be accurately reset.

[0095] For example, in this embodiment, the third reset member 8 is a fourth elastic member, which is a ring spring. The fourth elastic member is disposed between the spring pin 51 and the push plate 131. When the spring pin 51 slides along the slope 5231, the fourth elastic member undergoes elastic deformation. After the spring pin 51 passes the slope 5231, the fourth elastic member restores its deformation, thereby driving the spring pin 51 to reset.

[0096] In addition, it is worth noting that the box body 1 is provided with a shield 16, which is used to shield the push plate 131, the stop 12, the turntable 11 and the guide 52, thereby avoiding the impact on the user's experience due to the exposure of the above structures.

[0097] Understandably, in order to prevent the shield 16 from affecting the movement of the locking block 21, the top of the shield 16 is provided with a notch 161, through which the locking block 21 can move into or out of the shield 16.

[0098] Furthermore, in some embodiments, an installation cover can be provided on the outer wall of the housing 1, and the part of the push rod 13 extending out of the housing 1, the button 132 and the first reset member 6 are all placed inside the installation cover to avoid affecting the external aesthetics of the earphone case. By pressing the button 132, the push rod 13 is pushed to move, thereby unlocking and locking the housing 1 and the lid 2.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
