Description

Technical Field

[0001] This application belongs to the field of electronic device technology, and specifically relates to an earphone assembly. Background Technology

[0002] Wireless earbuds typically consist of earbuds and a charging case. When not in use, the earbuds are placed in the charging case for convenient storage and charging. Currently, the built-in battery capacity of earbuds is generally small, typically providing only 2-3 hours of battery life. Once the earbud batteries are depleted, they must be placed back in the charging case to recharge, and users must wait until the earbuds are fully charged before using them again, which limits their usability. Summary of the Invention

[0003] The purpose of this application is to provide an earphone assembly that can solve the problem of limited use of earphones in related technologies.

[0004] This application provides an earphone assembly, including: The earphone itself; The first battery is detachably connected to the earphone body; The second battery is detachably connected to the earphone body; An earphone case, the earphone case having a charging part and a receiving space, the receiving space including an earphone compartment, a first battery compartment and a second battery compartment, the first battery compartment being connected to the earphone compartment, and the second battery compartment being connected to the earphone compartment; The earphone body can be connected to at least one of the first battery and the second battery.

[0005] In this embodiment, by providing two batteries and battery compartments for housing them, the earphone case can charge both batteries simultaneously, resulting in two charged batteries. This ensures that the earphone body can always be connected to at least one of the batteries. For example, the earphone body can be connected to two batteries at the same time, thus ensuring continuous use of the earphone and effectively avoiding the problem of the earphone not working due to insufficient battery power. This prevents the use of the earphone from being limited by insufficient power and provides users with a better user experience. Attached Figure Description

Detailed Implementation

[0007] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0008] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0009] The following description, in conjunction with the accompanying drawings, explains the headphone assembly provided in the embodiments of this application.

[0010] Please refer to Figures 1 to 4This application provides an earphone assembly, which includes an earphone body 13, a first battery 11, a second battery 12, and an earphone case 20. The first battery 11 and the second battery 12 are both detachably connected to the earphone body 13. The earphone case 20 has a charging part (not shown) and a receiving space. The receiving space includes an earphone compartment 23, a first battery compartment 21, and a second battery compartment 22. The first battery compartment 21 and the second battery compartment 22 are both connected to the earphone compartment 23. The earphone compartment 23 can be used to accommodate the earphone body 13, the first battery compartment 21 can be used to accommodate the first battery 11, and the second battery compartment 22 can be used to accommodate the second battery 12. The earphone body 13 can be connected to at least one of the first battery 11 and the second battery 12.

[0011] The earphone assembly provided in this application embodiment, by setting two batteries and two battery compartments in the earphone case 20, allows the earphone case to alternately charge the two batteries through the charging unit. For example, when the first battery 11 is in the first battery compartment 21, the first battery 11 is charged, and when the second battery 12 is in the second battery compartment 22, the second battery 12 is charged. Alternatively, when both the first battery 11 and the second battery 12 are in the battery compartment, both batteries can be charged simultaneously. This ensures that the earphone body 13 can always be connected to at least one charged battery, thus ensuring continuous use of the earphone and effectively avoiding the problem of the earphone being unusable due to insufficient battery power. This prevents the use of the earphone from being limited by insufficient power and provides users with a better user experience.

[0012] It should be noted that the charging unit inside the earphone case can be a single unit that simultaneously charges the first battery 11 and the second battery 12; alternatively, it can be two charging units, each charging the first battery 11 and the second battery 12 respectively. Furthermore, the charging unit can be connected to the first battery 11 and the second battery 12 via a wired connection or wireless charging. The earphone case can be powered by an external power source to charge or supply power to the charging unit; this embodiment does not specifically limit this aspect.

[0013] Optionally, the headphone assembly has a first state and a second state. When the headphone assembly is in the first state, the headphone body 13 is connected to the first battery 11, and the headphone body 13 and the first battery 11 are located outside the receiving space of the headphone case 20, and the second battery 12 is received in the second battery compartment 22. When the headphone assembly is in the second state, the headphone body 13 is received in the headphone compartment 23, the first battery 11 is received in the first battery compartment 21, and the second battery 12 is received in the second battery compartment 22.

[0014] like Figure 2As shown, the earphone case 20 may include a case body and a lid. The earphone compartment 23, the first battery compartment 21, and the second battery compartment 22 are all disposed in the case body. For example, the lid may be connected to the case body and be rotatable relative to the case body to be in an open or closed state. Alternatively, as... Figure 1 As shown, the earphone case 20 may also consist only of the case body, with the earphone compartment 23, the first battery compartment 21, and the second battery compartment 22 all disposed within the case body. It is understood that the earphone case 20 may also have other possible structural shapes, and this embodiment does not specifically limit these.

[0015] Optionally, the headphone assembly also has a third state. In this third state, the headphone body 13 is connected to the second battery 12, and both the headphone body 13 and the second battery 12 are located outside the receiving space, while the first battery 11 is received inside the first battery compartment 21. That is, the headphone assembly can switch from the first state to the third state, switching the first battery 11 connected to the headphone body 13 to the second battery 12. For example, if the first battery 11 is depleted, the second battery 12 can be connected to the headphone body 13 to power it, and the first battery 11 can be returned to the first battery compartment 21 for charging, ensuring its continued use. Of course, the headphone assembly can also switch from the third state to the second state, which will not be elaborated here. This allows the headphone body 13 to use the two batteries alternately, ensuring continuous use and providing a better user experience.

[0016] In this embodiment, the earphone assembly includes a first battery 11 and a second battery 12. The earphone case 20 includes a first battery compartment 21 for accommodating the first battery 11 and a second battery compartment 22 for accommodating the second battery 12. For example, for ease of description, the earphone body 13, the first battery 11, and the second battery 12 can be considered as the earphone 10 in the earphone assembly. When the earphone 10 is detached from the earphone case 20, for example, when a user removes the earphone 10 from the earphone case 20, the earphone body 13 is connected to one of the first battery 11 and the second battery 12. That is, at this time, the earphone body 13 is connected to one battery, thus ensuring the normal use of the earphone 10, while the other battery is housed in the corresponding battery compartment. Taking the first battery 11 as an example, assuming that when the user takes the earphone 10 out of the earphone case 20, the earphone body 13 is connected to the first battery 11, and the earphone body 13 is powered by the first battery 11 to ensure normal use. The second battery 12 is still housed in the second battery compartment 22 of the earphone case 20. If the second battery 12 has a low charge, the second battery compartment 22 can charge the second battery 12. When the user puts the earphone 10 back into the earphone case 20, the earphone body 13 is housed in the earphone compartment 23, and the first battery 11 is also housed in the first battery compartment 21. The first battery compartment 21 can charge the first battery 11. If the user needs to continue using the earphone 10, since the second battery 12 is in a charging state during the use of the first battery 11, the earphone body 13 can be connected to the second battery 12 with a sufficient charge, so that the earphone body 13 is powered by the second battery 12, thus ensuring the continued use of the earphone 10. In this way, by setting up two batteries and battery compartments for housing the two batteries, when one battery powers the earphone body 13, the other battery can be charged through the battery compartment. This ensures that the earphone body 13 can always be connected to one of the batteries with sufficient power, thus ensuring the continuous use of the earphone 10. This effectively avoids the problem of the earphone 10 becoming unusable due to insufficient battery power, providing users with a better user experience.

[0017] Alternatively, when removing the earphone body 13, both the first battery 11 and the second battery 12 can be connected to and removed from the earphone body 13. This would allow the earphone body 13 to be powered by two batteries, which is more suitable for long-term use of the earphone 10. This eliminates the need for users to frequently replace batteries and improves the user experience.

[0018] Additionally, in the second state, such as Figure 1The earphone 10 shown has its main body 13 housed in the earphone compartment 23, a first battery 11 housed in the first battery compartment 21, and a second battery 12 housed in the second battery compartment 22. This means that when the earphone 10 is not in use, both batteries are housed in their respective compartments. Optionally, if the battery power is insufficient, the charging unit inside the earphone case 20 can charge the batteries to ensure that the batteries have sufficient power to supply the earphone main body 13 when the earphone 10 is needed.

[0019] Optionally, the charging unit and the first battery 11 and the second battery 12 may be provided with compatible contact points or charging points, so that the charging unit can charge the first battery 11 and the second battery 12 through the contact points or charging points.

[0020] Alternatively, the charging unit can be wirelessly charged with respect to the first battery 11 and the second battery 12. The specific structure of the wireless charging can be referenced from related technologies, and this application does not impose specific limitations on it.

[0021] In one optional embodiment, the earphone assembly further includes a power detection circuit, and the earphone case 20 further includes a limiting mechanism. When the power detection circuit detects that the power of the second battery 12 is less than the power of the first battery 11, the limiting mechanism restricts the movement of the second battery 12 toward the earphone case 23, enabling the earphone assembly to switch from the second state to the first state. When the power detection circuit detects that the power of the second battery 12 is greater than the power of the first battery 11, the limiting mechanism restricts the movement of the first battery 11 toward the earphone case 23, enabling the earphone assembly to switch from the second state to the third state.

[0022] In this embodiment, the earphone assembly includes a power detection circuit. For example, this power detection circuit may be disposed inside the earphone case 20. When the first battery 11 and / or the second battery 12 are housed in the corresponding battery compartment, the power detection circuit may detect the power level of the first battery 11 and / or the second battery 12 through a related sensor. The power detection circuit may be connected to a limiting mechanism, so that the limiting structure can restrict the movement of the first battery 11 or the second battery 12 based on the detection result of the power detection circuit.

[0023] For example, the limiting mechanism may include a first baffle and a second baffle. The first baffle is disposed at the connection between the first battery compartment 21 and the earphone compartment 23, and the second baffle is disposed at the connection between the second battery compartment 22 and the earphone compartment 23. The first and second baffles are connected to a control mechanism disposed within the earphone case 20. The control mechanism can control the extension and retraction of the first and second baffles, and the control mechanism is connected to a power detection circuit. Specifically, when the power detection circuit detects that the power of the second battery 12 is less than the power of the first battery 11, the control mechanism controls the second baffle to extend, thereby restricting the movement of the second battery 12 toward the earphone compartment 23. At this time, the first baffle can be in a retracted state, that is, it does not restrict the movement of the first battery 11, thereby allowing the earphone assembly to switch from the second state to the first state, that is, the first battery 11 can connect to the earphone body 13 and be removed with the earphone body 13. Alternatively, if the power detection circuit detects that the power of the second battery 12 is greater than that of the first battery 11, the control mechanism controls the first baffle to extend, thereby restricting the movement of the first battery 11 toward the earphone compartment 23. At this time, the second baffle can be in a retracted state, that is, it will not restrict the movement of the second battery 12, thereby allowing the earphone assembly to switch from the second state to the third state, that is, the second battery 12 can connect to the earphone body 13 and be removed with the earphone body 13. In this way, the movement and switching of the first battery 11 and the second battery 12 can be automatically realized through the control mechanism and the limiting mechanism, further improving the user's experience with the earphone assembly.

[0024] In this embodiment, the earphone assembly also has a fourth state. In this fourth state, the earphone body 13 is connected to the first battery 11 and the second battery 12, and all four batteries (earphone body 13, first battery 11, and second battery 12) are located outside the receiving space. That is, the earphone body 13 can be connected to two batteries simultaneously and then removed for use. Furthermore, the user can flexibly choose the number of batteries based on the estimated usage time. In scenarios requiring long-term use, the earphone body 13 can be connected to multiple batteries simultaneously to ensure continuous use; in scenarios requiring short-term use, the earphone body 13 can be connected to only one battery, thereby minimizing the overall weight of the earphone 10 and improving the user experience.

[0025] In one optional embodiment, the earphone case 20 includes a limiting mechanism. During the process of the earphone assembly switching from the second state to the first state, the limiting mechanism restricts the movement of the second battery 12 toward the earphone compartment 23, so that the second battery 12 is housed within the second battery compartment 22; and / or, during the process of the earphone assembly switching from the second state to the first state, the limiting mechanism releases the restriction on the first battery 11, so that the earphone body 13 drives the first battery 11 to move through the earphone compartment 23 to outside the housing space. Exemplarily, in this embodiment, the limiting mechanism may also refer to the above-described first and second baffles, using the first baffle to restrict or release the restriction on the first battery 11, and using the second baffle to restrict or release the restriction on the second battery 12, thereby allowing the first battery 11 and / or the second battery 12 to be confined within or moved out of the corresponding battery compartment. The specific implementation process can refer to the foregoing description, and will not be elaborated further here.

[0026] It should be noted that the earphone 10 typically includes a left earphone and a right earphone, such as Figure 1 As shown, the earphone case 20 also has two earphone compartments 23 for accommodating the left and right earphones, respectively. Each earphone compartment 23 is connected to a first battery compartment 21 and a second battery compartment 22. In subsequent embodiments, only one earphone and its corresponding earphone compartment 23, first battery compartment 21, and second battery compartment 22 will be described as an example.

[0027] Additionally, it should be noted that the first battery 11 and the second battery 12 can also be replaced manually. For example, when the first battery 11 is connected to the earphone body 13, if the first battery 11 is depleted, the user can remove the first battery 11 and place it back in the first battery compartment 21 for charging, and then remove the second battery 12 from the second battery compartment 22 and connect the second battery 12 to the earphone body 13 to power the earphone body 13, ensuring continued use of the earphone 10. Alternatively, other methods can be used to replace the first battery 11 and the second battery 12.

[0028] Optionally, the earphone case 20 includes a limiting mechanism, which includes a first limiting member, a first battery 11 having a first limiting portion, a second battery 12 having a second limiting portion, and the first limiting member being disposed between the first limiting portion and the second limiting portion; during the process of the earphone assembly switching from the second state to the first state, the first limiting member releases the limiting of the first limiting portion, and the first limiting member cooperates with the second limiting portion to limit the movement. For example, the first limiting member can be a magnet, the first limiting portion of the first battery 11 can also be a magnet, and the first limiting portion of the second battery 12 can also be a magnet. The first limiting member can move between the first battery 11 and the second battery 12. When the first limiting member moves to the point where it is attracted to the magnet of the second battery 12, the first limiting member also attracts the second battery 12, thereby preventing the movement of the second battery 12 and limiting the second battery 12. At this time, the first limiting member moves away from the first battery 11 and will not affect the movement of the first battery 11, that is, the limitation on the first battery 11 is released, and the first battery 11 can move with the headphone body 13 to the outside of the receiving space. In the same principle, the first limiting member can also move to the point where it is attracted to the magnet of the first battery 11, thereby limiting the first battery 11. At this time, it will not affect the movement of the second battery 12, and the second battery 12 can move with the headphone body 13 to the outside of the receiving space. In this way, the first limiting member, the first limiting part, and the second limiting part are set to achieve effective control of the first battery 11 and the second battery 12.

[0029] Optionally, both the first limiting portion and the second limiting portion are groove structures. During the process of the headphone assembly switching from the second state to the first state, at least a portion of the first limiting member moves toward the second limiting portion, causing the first limiting member to disengage from the first limiting portion to release the restriction on the first limiting portion, and causing the first limiting member to engage with the second limiting portion to limit the second battery. For example, the first limiting member can be a limiting rod, which can move between the first battery 11 and the second battery 12 to extend into the groove structure of the first battery 11 or into the groove structure of the second battery 12, thereby limiting the first battery 11 or the second battery 12. Specific implementation methods will be described in subsequent embodiments and will not be elaborated here.

[0030] Optionally, the first limiting member is a limiting rod. During the process of the headphone assembly switching from the second state to the first state, the first limiting member moves toward the second limiting part, so that one end of the first limiting member disengages from the first limiting part to release the limiting of the first battery, and the other end of the first limiting member is inserted into the second limiting part to limit the second battery.

[0031] For example, please refer to Figures 2 to 6 The first battery 11 includes a first groove 111 (i.e., a first limiting part), the first battery compartment 21 includes a first through hole (not shown) opposite to the first groove 111, the second battery 12 includes a second groove 121 (i.e., a second limiting part), the second battery compartment 22 includes a second through hole 221 opposite to the second groove 121, and the earphone case 20 also includes a control member 24 and a limiting rod 25 disposed between the first battery compartment 21 and the second battery compartment 22; wherein, when the earphone assembly switches from the second state to the first state, the control member 24 is used to control the limiting rod 25 to pass through the second through hole 221 and be embedded in the second groove 121, the second battery 12 is fixed in the second battery compartment 22, at this time the limiting rod 25 moves away from the first groove 111 of the first battery 11, that is, the limiting of the first battery 11 is released, so that the first battery 11 can be taken out with the earphone body 13. Similarly, during the process of switching the headphone assembly to the third state, the control component 24 is used to control the limiting rod 25 to pass through the first through hole and be embedded in the first groove 111. The first battery 11 is fixed in the first battery compartment 21. At this time, the limiting rod 25 moves away from the second groove 121 of the second battery 12, that is, the limiting of the second battery 12 is released, so that the second battery 12 can be taken out with the headphone body 13.

[0032] In this embodiment, a control member 24 and a limiting rod 25 are provided between the first battery compartment 21 and the second battery compartment 22. The control member 24 can control the movement of the limiting rod 25, so that the limiting rod 25 can move to pass through the first through hole and be embedded in the first groove 111 of the first battery 11. In this way, the limiting rod 25 fixes the first battery 11 in the first battery compartment 21, so that the first battery 11 cannot be removed. At this time, the second battery 12 is not fixed and is in a removable state. Then the earphone body 13 can be connected to the second battery 12, and the second battery 12 can be removed together with the earphone body 13. At this time, the second battery 12 supplies power to the earphone body 13, while the first battery 11 is fixed in the first battery compartment 21 by the limiting rod 25. Alternatively, the control element 24 can move the limiting rod 25 to the second groove 121 that passes through the second through hole 221 and is embedded in the second battery 12. In this way, the limiting rod 25 fixes the second battery 12 in the second battery compartment 22, and the second battery 12 cannot be removed. At this time, the first battery 11 is not fixed and is in a removable state. Then, the earphone body 13 can be connected to the first battery 11, and the first battery 11 can be removed together with the earphone body 13. At this time, the first battery 11 supplies power to the earphone body 13, while the second battery 12 is fixed in the second battery compartment 22 by the limiting rod 25.

[0033] In this way, the movement of the limiting rod 25 can be controlled by the control element 24, so that the limiting rod 25 can fix one of the first battery 11 and the second battery 12, while the one of the first battery 11 and the second battery 12 that is not fixed can be connected to the earphone body 13 and removed together with the earphone body 13, ensuring power supply to the earphone body 13 and ensuring normal use of the earphone 10. Optionally, in one possible implementation, the control element 24 can be a motor, and the limiting rod 25 can be a rotating shaft connected to the motor. The motor can control the movement direction of the rotating shaft by rotating forward or backward, thereby enabling the rotating shaft to move. The forward or reverse rotation of the motor can be controlled by the user. For example, the earphone case 20 also includes a button connected to the motor, and the user can control the forward or reverse rotation of the motor by touching the button.

[0034] Optionally, the first limiting member may further include a first limiting rod and a second limiting rod. During the process of the headphone assembly switching from the second state to the first state, the first limiting rod moves away from the first limiting part, causing the first limiting rod to disengage from the first limiting part to release the restriction on the first battery; the second limiting rod moves towards the second limiting part, causing the second limiting rod to engage with the second limiting part to limit the second battery. This embodiment also includes two limiting rods, which respectively control the first battery 11 and the second battery 12. In this way, the two limiting rods can simultaneously limit both batteries, that is, both batteries are limited in their respective battery compartments, thereby putting the headphone assembly in the second state; or they can simultaneously release the restriction on both batteries, that is, both batteries can be removed at the same time, putting the headphone assembly in the fourth state; or they can limit one battery and release the restriction on the other battery, thereby allowing one battery to be confined in the battery compartment and the other battery to be removed. In this way, the headphone assembly can flexibly switch between different states.

[0035] Optionally, the limiting mechanism includes a driving part, the driving part includes a driving coil, and the first limiting member includes a magnetic structure; during the process of the headphone assembly switching from the second state to the first state, the driving coil drives the first limiting member to move, so that the first limiting member can release the limiting of the first limiting part, and the first limiting member can cooperate with the second limiting part to limit.

[0036] For example, the driving part, namely the aforementioned control element 24, and the limiting rod 25 (first limiting element) are made of magnetic material. The control element 24 includes a control chip and a coil (such as...) wound around the limiting rod 25. Figure 3As shown, the coil is connected to a control chip, which changes the direction of the current within the coil to control the movement of the limiting rod 25 between the first battery 11 and the second battery 12. Understandably, by changing the direction of the current within the coil, the control chip can also change the direction of the magnetic field of the coil, thereby changing the direction of movement of the magnetic limiting rod 25, achieving the purpose of controlling the movement of the limiting rod 25. This allows the limiting rod 25 to fix the first battery 11 in the first battery compartment 21 or the second battery 12 in the second battery compartment 22. The control chip can be connected to the aforementioned power detection circuit, allowing it to change the direction of the current within the coil based on the power level detected by the power detection circuit, thus controlling the movement of the limiting rod 25. This ensures that the battery with more power can be removed along with the earphone body 13, ensuring that the earphone body 13 is powered by the battery with more power, effectively extending the usage time of the earphone 10.

[0037] In this embodiment, by setting up a control chip, coil, and magnetic limiting rod 25, the automatic operation of fixing and replacing the battery is realized, making the operation of the headphone assembly more convenient and effectively improving the user experience of the headphone assembly.

[0038] Optionally, the first battery 11 further includes a first magnetic element 112, and the earphone case further includes a second magnetic element 212. When the first battery 11 is housed in the first battery compartment 21, the first magnetic element 112 and the second magnetic element 212 are opposite to each other and attract each other to fix the first battery 11.

[0039] For example, the first battery 11 includes a first magnetic element 112, and the first battery compartment 21 in the earphone case includes a second magnetic element 212 disposed opposite to the first magnetic element 112. When the first battery 11 is housed in the first battery compartment 21, the first magnetic element 112 and the second magnetic element 212 attract each other, and the opening of the first groove 111 is opposite to the first through hole. In addition, the second battery 12 also includes a third magnetic element 122, and the second battery compartment 22 in the earphone case includes a fourth magnetic element 222 disposed opposite to the third magnetic element 122. When the second battery 12 is housed in the second battery compartment 22, the third magnetic element 122 and the fourth magnetic element 222 attract each other, and the opening of the second groove 121 is opposite to the second through hole 221.

[0040] For example, during the process of placing the first battery 11 back into the first battery compartment 21, that is, during the process of the first battery 11 moving into the first battery compartment 21, the second magnetic element 212 inside the first battery compartment 21 will generate a magnetic attraction to the first magnetic element 112, thereby promoting the rapid movement of the first battery 11 into the first battery compartment 21, so that the first magnetic element 112 and the second magnetic element 212 are attracted to each other, thereby allowing the first battery 11 to be stably housed in the first battery compartment 21. At this time, the opening of the first groove 111 on the first battery 11 is aligned with the first through hole of the first battery compartment 21, thus ensuring that the limiting rod 25 can pass through the first through hole and be embedded in the first groove 111, ensuring that the limiting rod 25 can limit the first battery 11. Alternatively, during the process of placing the second battery 12 back into the second battery compartment 22, the fourth magnetic element 222 inside the second battery compartment 22 will magnetically attract the third magnetic element 122, thereby promoting the rapid movement of the second battery 12 into the second battery compartment 22. This allows the second battery 12 to move until the third magnetic element 122 and the fourth magnetic element 222 attract each other, thus enabling the second battery 12 to be stably housed in the second battery compartment 22. At this time, the opening of the second groove 121 on the second battery 12 is aligned with the second through hole 221 of the second battery compartment 22. This ensures that the limiting rod 25 can pass through the second through hole 221 and be embedded in the second groove 121, ensuring that the limiting rod 25 limits the second battery 12.

[0041] In this embodiment of the application, by setting the first magnetic element 112, the second magnetic element 212, the third magnetic element 122 and the fourth magnetic element 222, the position of the first battery 11 in the first battery compartment 21 and the position of the second battery 12 in the second battery compartment 22 can be limited, thereby ensuring the alignment of the first groove 111 with the first through hole and the alignment of the second groove 121 with the second through hole 221, and ensuring that the limiting rod 25 can limit the first battery 11 and / or the second battery 12.

[0042] Optionally, the first battery 11 further includes a fifth magnetic element 113, and the earphone body 13 further includes a sixth magnetic element 131. When the earphone assembly is in the first state, the fifth magnetic element 113 and the sixth magnetic element 131 attract each other, so that the earphone body 13 is detachably connected to the first battery 11.

[0043] Please refer to the following for details. Figure 4The first battery 11 also includes a fifth magnetic element 113, and the earphone body 13 includes a sixth magnetic element 131 disposed opposite to the fifth magnetic element 113. Therefore, when the first battery 11 is connected to the earphone body 13, the force between the fifth magnetic element 113 and the sixth magnetic element 131 ensures the stability of the connection between the first battery 11 and the earphone body 13. Furthermore, the second battery 12 includes a seventh magnetic element 123, and the earphone body 13 includes an eighth magnetic element 132 disposed opposite to the seventh magnetic element 123. Therefore, when the second battery 12 is connected to the earphone body 13, the force between the seventh magnetic element 123 and the eighth magnetic element 132 ensures the stability of the connection between the second battery 12 and the earphone body 13.

[0044] Optionally, the magnetic attraction between the fifth magnetic element 113 and the sixth magnetic element 131 is greater than the magnetic attraction between the first magnetic element 112 and the second magnetic element 212; the magnetic attraction between the seventh magnetic element 123 and the eighth magnetic element 132 is greater than the magnetic attraction between the third magnetic element 122 and the fourth magnetic element 222. Therefore, when the first battery 11 needs to be removed from the first battery compartment 21, since the magnetic attraction between the first battery 11 and the earphone body 13 is greater than the magnetic attraction between the first battery 11 and the first battery compartment 21, it can be ensured that the first battery 11 can be removed from the first battery compartment 21. Furthermore, because the magnetic attraction between the first battery 11 and the earphone body 13 is greater, the stability of the connection between the first battery 11 and the earphone body 13 is effectively guaranteed, preventing the first battery 11 from detaching from the earphone body 13. Similarly, when it is necessary to remove the second battery 12 from the second battery compartment 22, since the magnetic attraction force between the second battery 12 and the earphone body 13 is greater than the magnetic attraction force between the second battery 12 and the second battery compartment 22, it can be ensured that the second battery 12 can be removed from the second battery compartment 22. Furthermore, since the magnetic attraction force between the second battery 12 and the earphone body 13 is relatively large, the stability of the connection between the second battery 12 and the earphone body 13 is effectively guaranteed, preventing the second battery 12 from detaching from the earphone body 13.

[0045] In this embodiment, the first battery 11 is slidably and detachably connected to the earphone body 13. During the process of the earphone assembly switching from the second state to the first state, the first battery 11 moves along the first battery compartment 21 toward the earphone compartment 23, and the first battery 11 slides relative to the earphone body 13 from the detachable position toward the connected position. When the earphone assembly is in the first state, the first battery 11 is located at the connected position to achieve connection with the earphone body 13. When the earphone assembly is in the second state, the first battery 11 is located at the detachable position so that it can be separated from the earphone body 13. Optionally, at the connected position, the first battery 11 and the earphone body 13 may each be provided with a magnetic element, and the connection between the first battery 11 and the earphone body 13 is achieved by the attraction of the magnetic elements. Of course, the first battery 11 and the earphone body 13 can also be connected by other structural arrangements, which will be described in subsequent embodiments and will not be elaborated here. The contact surface between the first battery 11 and the earphone body 13 is an arc surface, so that the first battery 11 can slide relative to the earphone body 13. Alternatively, the second battery 12 and the earphone body 13 can also adopt the same design, so that the second battery 12 and the earphone body 13 can be slidably and detachably connected.

[0046] Optionally, the first battery 11 has a first latching portion, and the earphone body 13 has a second latching portion that matches the first latching portion. A sliding guide structure is provided on either the first or second latching portion. The sliding guide structure has a limiting structure at the connection position to restrict the separation of the first battery 11 from the earphone body 13. The sliding guide structure also has a connecting structure at a detachable position to enable the latching of the first and second latching portions. For example, the first latching portion is an ear clip, and the second latching portion is a slot. The slot's channel and extension direction can be equivalent to the sliding guide structure, allowing the ear clip to slide within the slot. One end of the slot may have a limiting structure. When the ear clip slides to this position, the limiting structure may connect to the ear clip to restrict further movement of the first battery 11, thereby restricting the separation of the first battery 11 from the earphone body 13 and ensuring that the first battery 11 is connected to the earphone body 13 so that it can be removed with the earphone body 13.

[0047] Optionally, one of the first and second latching portions is a latching lug and the other is a latching groove. The latching lug includes a first part and a second part that are connected to each other. The orthographic projection of the first part onto the plane where the second part is located is within the range of the second part. The sliding guide structure surrounds and forms the latching groove. The connecting structure is a mounting hole that communicates with the latching groove.

[0048] In the second state, the second part is opposite to and extends into the mounting hole. During the transition from the second state to the first state, the first battery slides relative to the earpiece, causing the ear clip to slide from the mounting hole into the slot. The first part slides along the sliding guide structure, and the slot limits the second part, connecting the first battery to the earpiece. In the first state, the first battery slides to the connection position, the limiting structure restricts the sliding of the first part, and the slot limits the second part, connecting the first battery to the earpiece. During the transition from the first state to the second state, the first battery moves towards the first battery compartment. The first part of the first battery slides relative to the earpiece along the sliding guide structure from the connection position towards the detachable position. When the second limiting part disengages from the slot and is located within the mounting hole, the first battery can be separated from the earpiece.

[0049] For example, please refer to further details. Figures 4 to 9 The first battery 11 is connected to the earphone body 13 at one end, which is provided with a first ear clip 114. The earphone body 13 is provided with a first slot 133. When the earphone body 13 is connected to the first battery 11, the first ear clip 114 is fixed in the first slot 133. When the earphone is housed in the earphone case 20, the first ear clip 114 is not fixedly connected to the first slot 133. For example, the first slot 133 is an elongated slot, and the first earpiece 114 can slide in the first slot 133. The diameter of the opening at the first end of the first slot 133 is larger than the diameter of the opening at the second end of the first slot 133. When the first earpiece 114 slides to the second end of the first slot 133, it cannot be removed from the first slot 133, thus achieving a fixed connection between the first battery 11 and the earphone body 13. When the first earpiece 114 slides to the second end of the first slot 133, due to the larger diameter of the opening at the second end, it can be removed from the second end of the first slot 133. At this time, the first battery 11 can also be detached from the earphone body 13, that is, the first battery 11 is not fixedly connected to the earphone body 13. In this way, a detachable connection between the first battery 11 and the earphone body 13 can be achieved.

[0050] Please refer to the following for details. Figures 7 to 9The first slot 133 is also connected to a first mounting hole 134, the width of which is greater than the width of the first slot 133. The first ear 114 includes a first connecting part 1142 (i.e., the first part mentioned above) and a first engaging part 1141 (i.e., the second part mentioned above). The two ends of the first connecting part 1142 are respectively connected to the first engaging part 1141 and the first battery 11. The diameter of the first engaging part 1141 is less than or equal to the width of the first mounting hole 134 and greater than the width of the first slot 133. The diameter of the first connecting part 1142 is less than the diameter of the first engaging part 1141 and can slide in the first slot 133 and the first mounting hole 134. When the first connecting part 1142 slides into the first slot 133, the first ear 114 is fixed in the first slot 133. When the first connecting part 1142 slides into the first mounting hole 134, the first ear 114 is not fixedly connected to the first slot 133. Understandably, the first connecting part 1142 can slide in the first slot 133 and the first mounting hole 134, that is, the first ear clip 114 can slide in the first slot and the first mounting hole 134. The diameter of the first latching part 1141 in the first ear clip 114 is smaller than the width of the slot in the first mounting hole 134. Therefore, when the first ear clip 114 slides into the first mounting hole 134, the first latching part 1141 can be removed from the first mounting hole 134. At this time, the first ear clip 114 is not fixedly connected to the first slot 133, which can ensure that the first battery 11 can be detached from the earphone body 13. When the first ear clip 114 slides into the first slot 133, since the diameter of the first locking part 1141 is larger than the width of the first slot 133, the first locking part 1141 is locked into the first slot 133 and cannot be disengaged from the first slide. This ensures the fixed connection between the first ear clip 114 and the first slot 133, which in turn ensures the fixed connection between the first battery 11 and the earphone body 13.

[0051] For example, when the first battery 11 is housed in the first battery compartment 21 and the earphone body 13 is also housed in the earphone compartment 23, the first latching portion 1141 provided at one end of the first battery 11 is then received in the first mounting hole 134 of the earphone body 13 (e.g., Figure 9As shown), since the diameter of the first latching part 1141 is smaller than the width of the slot of the first mounting hole 134, the first latch 114 and the first slot 133 are not fixedly connected. Therefore, although the first battery 11 and the earphone body 13 are in contact, they are in a non-fixed connection state. If the control member 24 controls the limiting rod 25 to move into the first groove 111, the first battery 11 is fixed in the first battery compartment 21. Even if the earphone body 13 is removed, since the first battery 11 and the earphone body 13 are not fixedly connected, there will be no resistance to the removal of the earphone body 13, thus ensuring the smooth removal of the earphone body 13. If the control member 24 controls the limiting rod 25 to release the limiting of the first battery 11, the first battery 11 is not fixed in the first battery compartment 21. If the earphone body 13 is removed, the movement of the earphone body 13 will cause the first latching part 1141 of the first battery 11 to move into the first slot 133 (e.g., ...). Figure 8 As shown in the figure, the first ear clip 114 is fixedly connected to the first slot 133, which also makes the first battery 11 fixedly connected to the headphone body 13. At this time, the first battery 11 can be removed together with the headphone body 13, and the headphone body 13 can be powered by the first battery 11 to ensure the normal use of the headphone.

[0052] In this embodiment, the end of the second battery 12 connected to the earphone body 13 is provided with a second clip 124, and the earphone body 13 is provided with a second slot (not shown). When the earphone body 13 is connected to the second battery 12, the second clip 124 is fixed in the second slot. When the earphone is housed in the earphone case 20, the second clip 124 is not fixedly connected to the second slot. In this way, the second battery 12 and the earphone body 13 can be detachably connected, which facilitates the separation of the second battery 12 from the earphone body 13, and also allows for a fixed connection between the second battery 12 and the earphone body 13 when needed.

[0053] Optionally, the second slot is connected to a second mounting hole (see reference). Figure 8 and Figure 9 The first slot has a structure where the width of the second mounting hole is greater than the width of the second slot; the second ear 124 includes a second connecting part and a second engaging part (see reference). Figure 7 The first clip 124 has a structure that connects the two ends of the second connecting part to the second clip and the second battery 12, respectively. The diameter of the second clip is less than or equal to the width of the second mounting hole and greater than the width of the second slot. The diameter of the second connecting part is less than the diameter of the second clip and can slide in the second slot and the second mounting hole. When the second connecting part slides into the second slot, the second clip 124 is fixed in the second slot. When the second connecting part slides into the second mounting hole, the second clip 124 is not fixedly connected to the second slot.

[0054] Understandably, the second connecting part can slide in the second slot and the second mounting hole, that is, the second clip 124 can slide in the second slot and the second mounting hole. The diameter of the second latching part in the second clip 124 is smaller than the width of the slot in the second mounting hole. Therefore, when the second clip 124 slides into the second mounting hole, the second latching part can be removed from the second mounting hole. At this time, the second clip 124 and the second slot are not fixedly connected, which ensures that the second battery 12 can be detached from the earphone body 13. When the second clip 124 slides into the second slot, since the diameter of the second latching part is larger than the width of the second slot, the second latching part is latched in the second slot and cannot be detached from the second sliding. This ensures the fixed connection between the second clip 124 and the second slot, that is, it ensures the fixed connection between the second battery 12 and the earphone body 13.

[0055] For example, when the second battery 12 is housed in the second battery compartment 22 and the earphone body 13 is also housed in the earphone compartment 23, the second latching portion provided at one end of the second battery 12 is received in the second mounting hole of the earphone body 13. Thus, although the second battery 12 and the earphone body 13 are in contact, they are not in a fixed connection state. If the control member 24 controls the limiting rod 25 to move into the second groove 121 of the second battery 12, the second battery 12 is fixed in the second battery compartment 22. Even if the earphone body 13 is removed at this time, since the second battery 12 and the earphone body 13 are in a non-fixed connection state, there will be no resistance to the removal of the earphone body 13, thereby ensuring the smooth removal of the earphone body 13. If the control element 24 controls the limit rod 25 to release the limit on the second battery 12 at this time, the second battery 12 is not fixed in the second battery compartment 22. If the earphone body 13 is taken out at this time, the second locking part of the second battery 12 can be moved into the second slot by the movement of the earphone body 13, so that the second ear clip 124 is fixedly connected to the second slot, and the second battery 12 is fixedly connected to the earphone body 13. At this time, the second battery 12 can be taken out together with the earphone body 13, and the earphone body 13 can be powered by the second battery 12 to ensure the normal use of the earphone.

[0056] It should be noted that the first latch 114 and the second latch 124 may have the same structural shape, and the first slot 133 and the second slot may also have the same structural shape.

[0057] In this embodiment, the axis of the first battery compartment 21 intersects the opening direction of the earphone compartment 23, and / or the axis of the second battery compartment 22 intersects the axis of the earphone compartment, so that the first battery 11 slides relative to the earphone body 13 during the switching of the earphone assembly between the first state and the second state.

[0058] For example, please refer to Figure 2 The axis of the first battery compartment 21 intersects the axis of the second battery compartment 22. The first battery compartment 21 and the second battery compartment 22 are arranged in a "Y" shape, that is, tilted. For example, assuming the first battery 11 is housed in the first battery compartment 21 and the second battery 12 is connected to the earphone body 13, when the earphone is put back into the earphone case 20, the second battery 12 connected to the earphone body 13 will be pushed to the side without batteries, that is, into the second battery compartment 22. Since the first battery compartment 21 and the second battery compartment 22 are tilted, the earphone will become tilted at this time, allowing the second battery 12 to move into the second battery compartment 22. When it moves to a certain extent, the earphone body 13 contacts the earphone compartment 23. If the earphone is pressed down further, the second battery 12 will be squeezed against the earphone body 13. Due to the shape limitation of the earphone compartment 23 and the second battery compartment 22, the second battery 12 on the earphone and the earphone body 13 will form an angle, allowing it to be fully inserted into the earphone case 20. This deformation will rotate along the contact surface between the second battery 12 and the earphone body 13 (the contact surface is an arc). This rotation will release the latch between the earphone body 13 and the second battery 12, allowing the second battery 12 to be smoothly inserted into the second battery compartment 22, thus completely housing the earphone in the earphone case 20. This design ensures that when the earphone is placed in the earphone case 20, the earphone body 13 can contact both the first battery 11 and the second battery 12. When the earphone needs to be removed, one of the batteries can be connected to the earphone body 13, ensuring power supply and normal use of the earphone.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
