[0050] Please refer to Figures 1-8 This application provides an earphone housing, which includes a body 10, an inner cover 20, an outer cover 30, and a first elastic member 40.

[0051] Please refer to Figures 2-4 The main body 10 has a battery compartment 10a and an opening 10b communicating with the battery compartment 10a. The battery compartment 10a is used to hold a battery, and the battery can be placed into the battery compartment 10a through the opening 10b or removed from the battery compartment 10a through the opening 10b.

[0052] The inner cover 20 is removably pressed at the opening 10b to seal the battery compartment 10a, thereby achieving waterproof protection for the battery inside the battery compartment 10a.

[0053] The outer cover 30 is located on the side of the inner cover 20 away from the main body 10, that is, the inner cover 20 is located between the outer cover 30 and the main body 10. The outer cover 30 can be locked with the main body 10 to restrain the inner cover 20 or unlocked to expose the inner cover 20. In other words, locking the outer cover 30 with the main body 10 will restrain the inner cover 20, and unlocking the outer cover 30 from the main body 10 will expose the inner cover 20 and allow it to be separated from the main body 10.

[0054] The first elastic element 40 is disposed between the outer cover 30 and the inner cover 20. The outer cover 30 can be locked or unlocked with the body 10. When the outer cover 30 is locked with the body 10, the first elastic element 40 acts on the inner cover 20 to provide elastic force so that the inner cover 20 presses and seals the battery compartment 10a. When the outer cover 30 is unlocked from the body 10, the first elastic element 40 cannot act on the inner cover 20. Since the inner cover 20 is pressed against the opening 10b of the body 10, the inner cover 20 can be quickly separated from the body 10 to facilitate the removal of the battery and replacement with a new battery.

[0055] In the above embodiment, the inner cover 20 is pressed against the opening 10b to seal the battery compartment 10a. When the outer cover 30 is locked with the body 10, the first elastic member 40 acts on the inner cover 20 to provide elastic force, causing the inner cover 20 to press tightly and seal the battery compartment 10a, thereby achieving waterproof protection for the battery inside the battery compartment 10a. When the outer cover 30 is unlocked from the body 10, the inner cover 20 is exposed. Since the inner cover 20 is pressed against the opening 10b of the body 10, the inner cover 20 can be quickly separated from the body 10, allowing for the replacement of a new battery. This structure enables the battery to be detachable with simple and convenient disassembly, and also has good waterproof performance, making it suitable for rainy environments.

[0056] It is understood that the locking or unlocking structure of the outer cover 30 and the body 10 is not limited. In some embodiments, the earphone housing includes a hinge shaft 50, and the outer cover 30 is hinged to one side of the body 10 via the hinge shaft 50. The body 10 has a first locking part 11 on the opposite side, and the outer cover 30 has a second locking part 31 on the opposite side. The first locking part 11 and the second locking part 31 cooperate to lock the outer cover 30 to the body 10, or the first locking part 11 and the second locking part 31 separate to unlock the outer cover 30 from the body 10.

[0057] In this embodiment, the hinge shaft 50 can be integrally formed on either the outer cover 30 or the body 10, and a hinge hole that mates with the hinge shaft 50 is provided on the other. In other embodiments, the body 10 is provided with a protruding first hinge ear 15, which has a hinge hole, and the outer cover 30 is provided with a protruding second hinge ear, which also has a hinge hole. The hinge shaft 50 passes through the hinge hole of the first hinge ear 15 and the hinge hole of the second hinge ear, thereby realizing the hinge between the body 10 and the outer cover 30.

[0058] Understandably, the outer cover 30 can rotate about the axis of the hinge shaft 50. When it rotates toward the inner cover 20, the first elastic element 40 acts on the inner cover 20, thereby pressing the inner cover 20 to seal the battery compartment 10a. When it rotates in the opposite direction, the first elastic element 40 cannot act on the inner cover 20, thus facilitating the separation of the inner cover 20 from the body 10, and allowing the battery to be removed and replaced with a new battery.

[0059] It is understandable that the structure of the first locking part 11 and the second locking part 31 is not limited.

[0060] In some embodiments, the first locking part 11 is a groove formed on the outer wall of the body 10, and the second locking part 31 is a protrusion provided on the outer cover 30. The protrusion can be engaged into the groove, thereby locking the outer cover 30 and the body 10. Conversely, when the protrusion is disengaged from the groove, the outer cover 30 and the body 10 are unlocked.

[0061] The protrusion includes a first protrusion 311 and a second protrusion 312 connected to each other. The first protrusion 311 protrudes towards the body 10. When the outer cover 30 is rotated to engage with the body 10, the first protrusion 311 is located outside the groove. At this time, the second protrusion 312 protrudes towards the side of the groove, so that it can be inserted into the groove to achieve the locking of the outer cover 30 and the body 10.

[0062] In other embodiments, the first locking part 11 is a protruding protrusion formed on the outer wall of the body 10, and the second locking part 31 is a groove provided on the outer cover 30, wherein the part of the protrusion can be inserted into the groove.

[0063] In some embodiments, the outer cover 30 has a mounting groove 30a formed on its surface facing the inner cover 20, and a first elastic member 40 is disposed within the mounting groove 30a and partially extends out of the mounting groove 30a. The inner cover 20 has a positioning groove 20a. The mounting groove 30a can be located at the center of the outer cover 30, and the positioning groove 20a can be located at the center of the inner cover 20. When the outer cover 30 is engaged with the body 10, the mounting groove 30a and the positioning groove 20a are opposite each other along the height direction of the battery compartment 10a. The diameter of the mounting groove 30a can be smaller than the diameter of the positioning groove 20a, thereby allowing the spring to accurately fall into the positioning groove 20a during rotation.

[0064] When the outer cover 30 can be locked with the body 10, the first elastic member 40 is elastically pressed against the bottom wall of the positioning groove 20a and the bottom wall of the mounting groove 30a. That is, the first elastic member 40 is elastically compressed. At this time, the first elastic member 40 provides elastic force, which increases the resistance to the separation of the first locking part 11 and the second locking part 31, thereby preventing the outer cover 30 from unlocking from the body 10, which improves the reliability of locking the battery.

[0065] To further improve sealing, in some embodiments, the earphone housing includes a sealing ring 60. The end face of the body 10 facing the inner cover 20 is recessed to form a first step 12 surrounding the opening 10b. The end face of the inner cover 20 facing the body 10 is recessed to form a second step 21 opposite to the first step 12. The sealing ring 60 is disposed between the second step 21 and the first step 12. It is understood that the sealing ring 60 and the second step 21 of the inner cover 20 can be supported by the first step 12. Under the action of the first elastic member 40, the sealing ring 60, located between the second step 21 and the first step 12, is compressed and deformed by both, thereby better sealing between the inner cover 20 and the body 10, improving the sealing of the battery compartment 10a, and achieving a waterproof function.

[0066] The first step 12 can be formed by a recess at the position where the opening 10b of the body 10 connects with the end face, and the second step 21 can be formed by a recess at the position where the end face and the side wall of the inner cover 20 connect.

[0067] Please refer to Figure 5 In some embodiments, the second locking portion 31 is a protrusion provided on the outer cover 30, and a mark 313 indicating the unlocking direction is formed on the surface of the protrusion facing away from the body 10. It can be understood that the surface of the protrusion facing away from the body 10 is the surface exposed on the outside of the earphone. The aforementioned mark 313 indicating the unlocking direction can be used to quickly determine the unlocking direction, thereby facilitating the user to quickly replace the battery.

[0068] Please refer to Figure 3 In some embodiments, the end of the main body 10 away from the battery compartment 10a forms a curved ear hook portion 13. It is understood that the ear hook portion 13 is a structure that can be hung on the user's ear. That is, the earphone shell is the shell of an ear hook earphone, so that the end of the ear hook portion 13 away from the battery compartment 10a provides space for the battery compartment 10a and does not affect the ear hook function.

[0069] Please refer to Figures 6-8 In some other embodiments of this application, another structure is provided for locking or unlocking the outer cover 30 with the body 10.

[0070] The opening 10b is provided with a first sliding part 14. The outer cover 30 has a second sliding part 32, which can slide and engage with the first sliding part 14 and restrict the movement of the outer cover 30 in the non-sliding direction. That is, when the first sliding part 14 and the second sliding part 32 slide and engage, the outer cover 30 can only move along the sliding direction with the body 10 and cannot move in other directions. Specifically, when the sliding direction is radial, the outer cover 30 and the body 10 cannot move in the axial direction.

[0071] The outer cover 30 can slide and close the opening 10b under the sliding engagement of the second sliding part 32 and the first sliding part 14, or slide in the opposite direction and expose the opening 10b. It can be understood that when the outer cover 30 slides relative to the body 10 and closes the opening 10b, the battery is sealed inside the battery compartment 10a. When the outer cover 30 slides in the opposite direction and exposes the opening 10b, it is convenient to remove the battery and insert a new battery.

[0072] When the outer cover 30 slides and closes the opening 10b, the first elastic element 40 can generate an elastic force that resists the sliding of the outer cover 30, that is, it prevents the outer cover 30 from sliding and avoids exposing the opening 10b.

[0073] In the above embodiment, the second sliding part 32 can slide and cooperate with the first sliding part 14 to restrict the movement of the outer cover 30 in the non-sliding direction. The outer cover 30 can slide and close the opening 10b under the sliding cooperation of the second sliding part 32 and the first sliding part 14. At this time, the first elastic member 40 can generate an elastic force that resists the sliding of the outer cover 30, thereby closing the opening 10b, that is, closing the battery compartment 10a, thus preventing the battery from sliding out of the battery compartment 10a. The outer cover 30 can slide in the opposite direction and expose the opening 10b under the sliding cooperation of the second sliding part 32 and the first sliding part 14, so that the battery inside can be directly taken out. The above structure of closing and opening the battery compartment 10a by sliding is relatively simple, can achieve a small volume occupation to improve the applicability, and the sliding action is relatively simple and easy to operate.

[0074] It is understood that the specific structures of the first sliding part 14 and the second sliding part 32 are not limited. In some embodiments, the sidewall of the body 10 at one end of the opening 10b forms a through notch 10d. The first sliding part 14 is a groove formed on the inner wall of the battery compartment 10a, and the groove is opposite to the notch 10d. The second sliding part 32 is a protruding latch formed on the outer cover 30. The outer cover 30 can slide, allowing the latch to slide from the notch 10d into the groove to restrain the movement of the outer cover 30 in the non-sliding direction. Specifically, the groove is an arc-shaped groove, and the latch is an arc-shaped protrusion, disposed on the outer side wall of the outer cover 30.

[0075] It is understandable that the first sliding part 14 of the groove structure and the second sliding part 32 of the protrusion structure can achieve the sliding engagement between the outer cover 30 and the body 10, and the overall volume is relatively small, making it suitable for small-volume open-back headphones.

[0076] In some embodiments, the first elastic member 40 is connected to one of the inner cover 20 or the outer cover 30, and the other of the inner cover 20 or the outer cover 30 is provided with a slot 20b. That is, the first elastic member 40 can be connected to the outer cover 30 or the inner cover 20, and the slot 20b is located on the surface of the other of the inner cover 20 or the outer cover 30, which is opposite to the one of the inner cover 20 or the outer cover 30 to which the first elastic member 40 is connected.

[0077] For ease of description, the following explanation will take the example of the first elastic element 40 being connected to the outer cover 30.

[0078] When the outer cover 30 slides to the position of closing the opening 10b, the first elastic member 40 can elastically engage in the slot 20b and press against the inner wall of the slot 20b. The outer cover 30 can slide under the action of external force to overcome the elastic force of the first elastic member 40, so that the first elastic member 40 can exit the slot 20b.

[0079] When the outer cover 30 slides along the first direction to the position of closing the opening 10b, the first elastic member 40 can elastically engage with the slot 20b and press against the inner wall of the slot 20b. Specifically, when the outer cover 30 slides, the first elastic member 40 presses against the surface of the inner cover 20 and slides on the surface of the inner cover 20. At this time, the first elastic member 40 is in an energy-storing state. When the outer cover 30 slides to the position of closing the opening 10b, the first elastic member 40 can release its elastic energy to elastically engage with the slot 20b, thereby hindering the sliding of the outer cover 30. The first elastic member 40 engaged with the slot 20b is still in an energy-storing state, thereby pressing against the inner wall of the slot 20b, and thus generating an elastic force that presses the inner cover 20 against the opening 10b.

[0080] The outer cover 30 can slide under the action of an external force to overcome the elastic force of the first elastic member 40, so that the first elastic member 40 is disengaged from the slot 20b. That is, when the battery needs to be replaced, the outer cover 30 is slid under the action of an external force to overcome the elastic force of the first elastic member 40, so that the first elastic member 40 is disengaged from the slot 20b, thereby exposing the opening 10b.

[0081] It is understandable that, during the sliding engagement of the second sliding part 32 and the first sliding part 14, the first elastic member 40 is held by the inner shell and moves away from the inner shell to store energy. Therefore, a clearance groove is opened on the surface of the outer shell facing the inner shell. The clearance groove can reduce the material and volume of the outer shell and provide space for the deformation of the first elastic member 40.

[0082] In some embodiments, the first elastic element 40 is a sheet structure, including a connecting segment 41 and a hook segment 42 connected to each other. The connecting segment 41 is inserted into a slot in the outer cover 30, and the hook segment 42 is inclined relative to the connecting segment 41. It is understood that the inclined hook segment 42 can bend relative to the connecting segment 41 to store energy when it abuts against the inner shell. The hook segment 42 can elastically engage with or disengage from the slot 20b.

[0083] This application embodiment also provides an earphone, which includes an earphone shell and a battery. One end of the body 10 has a battery compartment 10a, in which the battery is disposed. The other end of the body 10 has an ear hook portion 13.

[0084] In some embodiments, the earphone includes a second elastic element 80 disposed at one end of the battery compartment 10a opposite to the opening 10b. The second elastic element 80 is capable of generating an elastic force that moves the battery outward from the opening 10b. It is understood that after the outer cover 30 is unlocked, the aforementioned elastic force can push the battery and the inner cover 20 to move, thereby separating the inner cover 20 from the body 10, facilitating the removal of the inner cover 20 and the battery.

[0085] The shape and number of the second elastic element 80 are not limited, as long as they can provide elastic force to push the battery and the inner cover 20. In some embodiments, the number of the second elastic element 80 is two.

[0086] In some embodiments, the earphone includes a battery control board 70, and a fixing groove 10c is provided on the side of the battery compartment 10a away from the opening 10b. The battery control board 70 is disposed in the fixing groove 10c, and the battery is electrically connected to the battery control board 70.

[0087] Furthermore, conductive electrode plates are provided on the battery control board 70 to achieve electrical connection between the battery and the battery control board 70. The conductive electrode plates and the second elastic member 80 can be two separately formed components. In some embodiments, the conductive electrode plate is the second elastic member 80, meaning the second elastic member 80 also functions as an electrical connection between the battery and the battery control board 70.

[0088] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
