[0031] The box can house an audio player, thus protecting the audio player inside.

[0032] In related technologies, the lifespan of the main body of the box and the opening of the lid on the main body are different, and the box cannot be used again due to the short lifespan of the part of the box.

[0033] The inventors of this disclosure have discovered that a housing and earphones can be provided. The housing may include: a main body, a cover, and a connecting structure. The main body may have a cavity with an opening. The cover can switch between two states: covering and uncovering the opening. When the cover is uncovered, the earphone unit can be inserted into or removed from the cavity through the opening. The cover is provided with a connector, and the main body is provided with a connecting structure adapted to the connector. The cover can move relative to the main body in a first or second manner. When the cover moves relative to the main body in the first manner, the connector and the connecting structure form a first adaptation relationship, allowing the cover to be fixed to the main body (or connected to the main body) and switch between the two states of covering and uncovering the opening. When the cover moves relative to the main body in the second manner, the connector and the connecting structure form a second adaptation relationship, allowing the cover to detach from the main body. This detachment design allows for the replacement of either the main body or the cover, thereby extending the lifespan of the shorter component of the main body or the cover, thus extending the lifespan of the housing and improving its economic efficiency.

[0034] First aspect

[0035] This disclosure provides a housing 10, see [link to relevant documentation] Figures 1 to 5The box body 10 may include: a main body 11, a cover 12, and a connecting structure 13. The main body 11 has a cavity 111 with an opening 112. The cover 12 switches between covering and not covering the opening 112. When the cover 12 covers the opening 112, the cavity volume of the cavity 111 is equal to the cavity volume of the cavity 111 when the cover 12 does not cover the opening 112. The cover 12 may include: a connector 121. The connecting structure 13 is disposed on the main body 11. The cover 12 moves first relative to the main body 11, and the connector 121 and the connecting structure 13 first cooperate to fix the cover 12 to the main body 11. The cover 12 moves second relative to the main body 11, and the connector 121 and the connecting structure 13 second cooperate to detach the cover 12 from the main body 11. The direction of the first movement intersects the direction of the second movement.

[0036] The main body 11 has an internal cavity 111 that can accommodate the earphone unit. The cavity 111 has an opening 112, which connects the cavity 111 to the space outside the main body 11, allowing the earphone unit to be placed and removed through the opening 112. The cavity 111 may include independent first spaces 1111 and second spaces 1112, and the first spaces 1111 and second spaces 1112 may respectively conform to the contours of two earphone units, so that when the two earphone units are respectively placed in the first spaces 1111 and second spaces 1112, their positions relative to the main body 11 are fixed. The first spaces 1111 and second spaces 1112 may be symmetrically arranged to accommodate two structurally symmetrical earphone units. Here, the earphone unit can be an earphone that supports wired transmission or an earphone that supports wireless transmission; the earphone unit may include acoustic components such as a diaphragm, voice coil, and magnetic circuit system to convert electrical signals into sound waves for output.

[0037] The cover 12 can cover or not cover the opening 112. When the opening 112 is covered, it reduces the entry of dust, foreign objects, etc., into the cavity 111 through the opening 112, and reduces the probability of the earphone unit inside the cavity 111 falling out and malfunctioning through the opening 112, thus protecting the earphone unit inside the cavity 111. When the opening 112 is not covered, it exposes the opening 112, allowing the earphone unit to be placed and removed. The cavity volume of the cavity 111 remains unchanged in both the covered and uncovered states; that is, the movement or deformation of the cover 12 does not change the effective volume of the cavity 111. The cover 12 can be made of plastic with a fixed shape, or of leather that can deform during the switching between covering and uncovering the opening 112, or of other materials.

[0038] The connector 121 and the connecting structure 13 have a first mating relationship and a second mating relationship. In the first mating relationship, the connector 121 is connected to the connecting structure 13 so that the cover 12 is connected to the main body 11, and the cover 12 can switch between covering the opening 112 and not covering the opening 112. In the second mating relationship, the connector 121 is separated from the connecting structure 13 so that the cover 12 can be detached from the main body 11, and then another cover 12 can be connected to the detached main body 11, or the detached cover 12 can be connected to another main body 11, thereby allowing the main body 11 or the cover 12 of the box 10 to be replaced. The cover 12 achieves the first mating relationship (or locking relationship) with the main body 11 through a first movement relative to the main body 11, and achieves the second mating relationship (or unlocking relationship) with the main body 11 through a second movement relative to the main body 11, and the angle between the direction of the first movement and the direction of the second movement can be an acute angle.

[0039] See one example. Figures 1 to 5 The housing 10 may include: a main body 11, a cover 12, and a connecting structure 13. The main body 11 has a cavity 111, which is provided with a first space 1111 and a second space 1112 that are independent of each other, and the cavity 111 has an opening 112. Two earphone units can be located in the first space 1111 and the second space 1112 within the cavity 111, and can be removed through the opening 112. The cover 12 can be connected to or not connected to the main body 11 through the cooperation of a connector 121 and a connecting structure 13 provided on the main body 11. When connected, the cover 12 can switch between covering the opening 112 and not covering the opening 112, and when the cover 12 covers the opening 112, the cavity volume of the cavity 111 is equal to the cavity volume of the cavity 111 when the cover 12 does not cover the opening 112. The cover 12 is relative to the main body 11 along a first direction (e.g., Figures 3 to 5 The cover 12 moves in the X direction (as shown in the image) to allow the connector 121 to engage with the connecting structure 13 in a first engagement (e.g., locking), and to fix the cover 12 to the body 11; the cover 12 moves relative to the body 11 in a second direction (e.g., along the X direction) to allow the connector 121 to engage with the connecting structure 13 in a first engagement (e.g., locking), and to fix the cover 12 to Figures 3 to 5 The first direction (in the Y direction) moves a second way, so that the connector 121 can engage with the connecting structure 13 in a second way (such as unlocking), and the cover 12 is detached from the body 11; wherein the angle between the first direction and the second direction is an acute angle.

[0040] In this embodiment, the housing 10 may include a main body 11, a cover 12, and a connecting structure 13. The main body 11 has an interior cavity 111 with an opening 112. The cover 12 can switch between covering and not covering the opening 112. When the cover 12 is not covering the opening 112, the earphone unit can be inserted into or removed from the cavity 111 through the opening 112. The cover 12 has a connector 121, and the main body 11 has a connecting structure 13 that matches the connector 121. 2. The cover 12 can move in a first direction relative to the main body 11, or move in a second direction. When the cover 12 moves in the first direction relative to the main body 11, the connector 121 and the connecting structure 13 form a first type of engagement, allowing the cover 12 to be securely connected to the main body 11, thereby enabling the cover 12 to switch between covering and not covering the opening 112. When the cover 12 moves in the second direction relative to the main body 11, the connector 121 and the connecting structure 13 enter a second type of engagement, allowing the cover 12 to be separated from the main body 11. The separation design allows for the replacement of either the main body 11 or the cover 12, enabling the replacement of parts with shorter service lives. This extends the overall lifespan of the box 10 and improves its economic efficiency and sustainable use value.

[0041] In some embodiments, see Figures 3 to 5 One end of the connector 121 is a raised arc-shaped portion 1211; the connecting structure 13 has a target surface 131 and is movable relative to the main body 11; during the first movement of the cover 12 relative to the main body 11, the target surface 131 moves relative to the main body 11 under the action of the first movement of the cover 12, and the arc-shaped portion 1211 guides the connector 121 to move along the target surface 131 for the first time, so that the connector 121 and the connecting structure 13 first engage.

[0042] In other words, during the first movement of the cover 12 relative to the main body 11, the target surface 131 can translate relative to the main body 11 to form a clamping space 134 for clamping the connector 121 between the target surface 131 and the main body 11, and clamp the connector 121 in the clamping space 134, thereby realizing the first engagement between the connector 121 and the connecting structure 13.

[0043] In this embodiment, the arc-shaped portion 1211 of the connector 121 can guide the connector 121 to move quickly along the target surface 131 of the connecting structure 13, so as to quickly achieve the first engagement between the connector 121 and the connecting structure 13. The arc-shaped portion 1211 can reduce the probability of scratches on the structure that contacts the arc-shaped portion 1211 during the movement of the connector 121.

[0044] In some embodiments, see Figures 3 to 5 During the second movement of the cover 12 relative to the main body 11, the target surface 131 moves relative to the main body 11 under the action of the second movement of the cover 12, and the connector 121 moves second along the target surface 131, so that the connector 121 and the connecting structure 13 are in second engagement.

[0045] In other words, during the second movement of the cover 12 relative to the main body 11, the target surface 131 can be translated relative to the main body 11 again. This translation can increase the size of the clamping space 134 between the target surface 131 and the main body 11, so that the connector 121 can move along the target surface 131 for the second time and disengage from the target surface 131, thereby realizing the second engagement of the connector 121 and the connecting structure 13.

[0046] In this embodiment, by moving the target surface 131 relative to the main body 11 again, the connector 121 can act on the target surface 131 in the second direction and make a second movement, thereby quickly realizing the second engagement of the connector 121 and the connecting structure 13.

[0047] In some embodiments, the connector 121 is in a first shape under a first movement; the connector 121 is in a second shape under a second movement; the first shape and the second shape are consistent.

[0048] The connector 121 can be a rigid structural component made of materials such as plastic or metal, with sufficient rigidity to maintain shape stability during different movements, thereby reducing the probability of affecting motion accuracy and operational reliability due to its own deformation.

[0049] In some embodiments, see Figures 3 to 5 The main body 11 has a groove 113, which has a first sidewall 1131 and a second sidewall 1132. The connecting structure 13 is disposed in the groove 113 and may include a first target member 132 and an elastic structure 133. The first target member 132 has a target surface 131, which is opposite to the first sidewall 1131 of the groove 113 and forms a clamping space 134 for clamping the connecting member 121. The elastic structure 133 is disposed between the first target member 132 and the second sidewall 1132, and the elastic deformation of the elastic structure 133 can cause the target surface 131 to move relative to the main body 11 and then return to its original position.

[0050] Groove 113 can be like Figures 1 to 5The surface shown on the outer side of the main body 11 can also be located on the inner surface of the corresponding cavity 111 of the main body 11. The groove 113 is used to accommodate the connector 121 and the connecting structure 13 of the cover 12. The first target member 132 forms a target surface 131 on the side near the first sidewall 1131, and the target surface 131 and the first sidewall 1131 form a clamping space 134 for clamping the connector 121. The elastic structure 133 can be located between the target surface 131 and the second sidewall 1132 and can provide an elastic preload to the first target member 132. During the first movement of the cover 12, the cover 12 squeezes the first sidewall 1131 and the elastic structure 133, causing the target surface 131 to move relative to the main body 11 in a direction away from the first sidewall 1131, and causing the elastic structure 133 to generate a compression amount. Then the connector 121 can move from the clamping opening of the clamping space 134 along the target surface 121. The surface 131 moves first and is clamped in the clamping space 134 to achieve the first engagement between the connector 121 and the connecting structure 13, and the elastic structure 133 restores its deformation and drives the target surface 131 to reset; and, by external force, the connector 121 of the cover 12 located in the clamping space 134 can push the target surface 131 to move relative to the main body 11 in a direction away from the first sidewall 1131, so that the connector 121 can move first along the target surface 131 from the clamping opening of the clamping space 134 and disengage from the clamping space 134 to achieve the second engagement between the connector 121 and the connecting structure 13, and the elastic structure 133 restores its deformation and drives the target surface 131 to reset.

[0051] In this embodiment, a groove 113 is provided on the main body 11, and the connecting structure 13 can be disposed in the groove 113 and cooperate with the first side wall 1131 of the groove 113 to form a clamping space 134 for clamping the connector 121. When the connector 121 is clamped in the clamping space 134, the cover 12 can be connected to the main body 11, thereby realizing that the cover 12 covers or does not cover the opening 112, and the connector 121 can be detached from the clamping space 134, so as to facilitate the replacement of at least one of the cover 12 and the main body 11.

[0052] In some embodiments, see Figures 3 to 5 The first target component 132 may include: a first part 1321, a second part 1322 and a third part 1323. The two ends of the second part 1322 are connected to the first part 1321 and the third part 1323 respectively. The surface of the first part 1321 facing away from the second part 1322 is the target surface 131. The second part 1322 is slidably inserted through the second sidewall 1132. The third part 1323 is located inside the main body 11 corresponding to the second sidewall 1132. The elastic structure 133 is sleeved on the second part 1322, and the two ends of the elastic structure 133 in the elastic direction abut against the first part 1321 and the second sidewall 1132 respectively.

[0053] The first part 1321, the second part 1322 and the third part 1323 of the first target member 132 cooperate to form an I-shaped structure. Parts of the third part 1323 and the second part 1322 are slidably embedded in the main body 11 so that the first target member 132 can slide back and forth in a direction perpendicular to the second side wall 1132, thereby allowing the target surface 131 of the first part 1321 facing away from the third part 1323 to approach or move away from the first side wall 1131 to define the clamping space 134.

[0054] The elastic structure 133 can be a spring, a rubber sleeve, or other structure. It is sleeved on the second part 1322 and abuts against the surface of the first part 1321 facing the third part 1323 and the second sidewall 1132, respectively. It can generate different compression amounts as the position of the target surface 131 changes.

[0055] In this embodiment, the first target component 132 includes a first part 1321, a second part 1322, and a third part 1323. The three parts cooperate to form an I-shaped structure, making the structure of the first target component 132 simple and easy to mass-produce. The elastic structure 133 is fitted on the second part 1322 in the middle of the I-shaped structure so that it can cooperate with the connector 121 to deform during the first and second movements of the cover 12, thereby supporting the switching between the connector 121 and the connecting structure 13 between the first and second cooperation.

[0056] In some embodiments, see Figure 3 and Figure 4 The cover 12 also covers the opening of the groove 113. In other words, the cover 12 extends towards the opening to cover it, thereby improving the visual appearance of the box 10 and reducing the chance of dust, foreign objects, etc. entering the groove 113 through the opening.

[0057] In some embodiments, see Figure 4 and Figure 5In the clamping opening of the clamping space 134, the first sidewall 1131 and the target surface 131 protrude towards the target surface 131 and form a limiting protrusion 1133. The target surface 131 is inclined away from the first sidewall 1131 and forms a guide slope 1311. The connector 121 moves along the guide slope 1311 for the first time and engages with the connecting structure 13 for the first time. When the connector 121 engages with the connecting structure 13 for the first time, the connector 121 is clamped in the clamping space 134, and one end of the connector 121 abuts against the side of the clamping space 134 corresponding to the limiting protrusion 1133. Thus, when the connector 121 moves toward the clamping space 134, it can enter the clamping space 134 along the guide ramp 1311, thereby making the connection between the connector 121 and the connecting structure 13 faster and smoother. When the connector 121 is in the clamping space 134, the end surface of the connector 121 corresponding to the clamping opening of the clamping space 134 can abut against the limiting protrusion 1133, thereby reducing the probability that the connector 121 clamped in the clamping space 134 will detach from the clamping space 134 on its own.

[0058] Second aspect

[0059] This disclosure provides an earphone, which may include: a main body 11, two earphone units, a cover 12, and a connecting structure 13. The main body 11 has a cavity 111 with an opening 112. The two earphone units are located inside the cavity 111. The cover 12 switches between covering and not covering the opening 112. When the cover 12 covers the opening 112, the cavity volume of the cavity 111 is equal to the cavity volume of the cavity 111 when the cover 12 does not cover the opening 112. The cover 12 includes: a connector 121; the connecting structure 13 is disposed on the main body 11. The cover 12 moves first relative to the main body 11, and the connector 121 and the connecting structure 13 first cooperate to fix the cover 12 to the main body 11. The cover 12 moves second relative to the main body 11, and the connector 121 and the connecting structure 13 second cooperate to detach the cover 12 from the main body 11. The direction of the first movement intersects the direction of the second movement.

[0060] The cavity 111 may include independent first space 1111 and second space 1112, and the first space 1111 and second space 1112 may respectively conform to the outline of the two earphone units, so that when the two earphone units are respectively placed in the first space 1111 and the second space 1112, their positions relative to the main body 11 are fixed; the first space 1111 and second space 1112 may be symmetrically arranged to accommodate two structurally symmetrical earphone units, such as the earphone unit corresponding to the left ear and the earphone unit corresponding to the right ear as two structurally symmetrical earphone units. Here, the earphone unit may be an earphone that supports wired transmission or an earphone that supports wireless transmission; the earphone unit may include acoustic components such as a diaphragm, voice coil, and magnetic circuit system to convert electrical signals into sound waves for output.

[0061] In this embodiment, the cover 12 can be detachably connected to the connection structure 13 on the main body 11 via the connector 121 thereon. When the cover 12 and the main body 11 are connected, the cover 12 can cover or not cover the opening 112. When the opening 112 is not covered, the earphone unit can be inserted into or removed from the cavity 111 through the opening 112. When the cover 12 covers the opening 112, the cover 12 and the main body 11 cooperate to protect the earphone unit in the cavity 111. When the cover 12 and the main body 11 are separated, either the main body 11 or the cover 12 can be replaced to replace the part with a short service life. In this way, the service life of the entire housing 10 can be extended, and the economic efficiency and sustainable use value of the housing 10 can be improved.

[0062] In some embodiments, see Figure 2 The cover 12 includes a second target member 122, which can switch between a first form and a second form and maintain both forms; when the second target member 122 maintains the first form, the cover 12 covers the opening 112; when the second target member 122 maintains the second form, the cover 12 does not cover the opening 112.

[0063] See Figure 2As shown, the second target component 122 can be a spring structure that fits onto the cover 12, and the spring structure is arc-shaped and has a first elasticity and a second elasticity in opposite directions. During the process of the cover 12 switching from a state covering the opening 112 to a state not covering the opening 112, the external force applied to the cover 12 can cause the second target component 122 to perform the first elasticity, so that the arc direction of the second target component 122 changes in the opposite direction and is in a second form. The second target component 122 can maintain the second form after the change in arc direction, thereby preventing the cover 12 from switching to a state covering the opening 112 on its own. Conversely, during the process of the cover 12 switching from a state not covering the opening 112 to a state covering the opening 112, the external force applied to the cover 12 can cause the second target component 122 to perform the second elasticity, so that the arc direction of the second target component 122 changes in the opposite direction (or returns to its original state) and is in a first form. The second target component 122 can maintain the first form after the change in arc direction, thereby preventing the cover 12 from switching to a state not covering the opening 112 on its own.

[0064] In this embodiment, by providing a second target element 122 on the cover 12, and by ensuring that the second target element 12 remains in a first state when the cover 12 covers the opening 112, the cover 12 is prevented from automatically switching to a state where it does not cover the opening 112. Simultaneously, the second target element 122 can also remain in a second state when the cover 12 does not cover the opening 112, thus preventing the cover 12 from automatically switching to a state where it covers the opening 112. Therefore, the cover 12 can be stably maintained in the open state when opened (i.e., the opening 112 is open) and stably maintained in the closed state when closed (i.e., the opening 112 is closed). This effectively avoids the need for the user to continuously apply external force to maintain the position of the cover 12 after opening or closing operations, improving operational convenience and enabling one-handed operation.
