[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0015] The embodiment of the present application provides a headset assembly. The headset assembly includes a headset case 10 and a headset. The headset case 10 is used to accommodate the headset. Specifically, the headset assembly described in the embodiment of the present application may include at least two headsets. The headset assembly is, for example, a TWS (True Wireless) headset assembly, or other headsets that need to be charged through the headset case 10, or a neck-worn wireless headset assembly, or a wired headset assembly, etc.

[0016] The following takes the headset assembly as a TWS headset assembly as an example for illustration.

[0017] The TWS headset assembly may include a headset case 10 and two headsets. The headset case 10 is used to accommodate the headsets and charge the headsets after the headsets are placed in the headset case 10.

[0018] The headset case 10 can charge the headset. When the headset is accommodated in the headset case 10, it can be electrically connected to the headset, and then charge the headset. For example, charging contacts ( Figure 2 shown but not labeled) may be provided in the headset case 10, and corresponding charging contacts (not shown in the figure) are also provided on the headset. When the headset is placed in the headset case 10, the charging contacts of the headset and the charging contacts of the headset case 10 can be in contact to achieve electrical connection. Of course, the headset case 10 can also perform wireless charging on the headset. The headset case 10 and the headset can be structurally connected and / or electrically connected by a magnetic attraction method. When the headset is placed in the headset case 10, the headset case 10 and the headset are magnetically attracted.

[0019] The headset case 10 may be provided with a prompt component, such as a display screen or an LED light, etc., which can be used to prompt corresponding information, such as the battery level, etc. The headset case 10 may also be provided with a charging interface (not shown in the figure), such as a USB interface, a TYPE-C interface, a MIN-USB interface, a Lighting interface.

[0020] The two earphones can be divided into a main earphone and a sub - earphone. The main earphone can communicate and connect with external devices. For example, communication can be achieved through Bluetooth technology. External devices can be, for example, mobile phones, tablets, smart watches, laptop computers, etc. The sub - earphone can communicate with the main earphone. The data sent by the external device can be sent to the main earphone and simultaneously sent from the main earphone to the sub - earphone, so that the main and sub - earphones can receive the data asynchronously as much as possible.

[0021] In some embodiments, in combination with Figure 1 and Figure 2 , the earphone case 10 includes a case body, a knob 124, and an electronic control board. The case body is used to accommodate the earphones, and the electronic control board is disposed inside the case body. The knob 124 is disposed on the case body and partially protrudes from the surface of the case body so that the user can touch the knob 124 outside the case. The knob 124 can rotate relative to the case body about a preset axis. The knob 124 is configured to be operated by the user to rotate about the preset axis, receive the operation input by the user, so that the electronic control board can detect the rotation of the knob 124 through a detection element, and then control the earphone to implement a preset function corresponding to the operation input by the user. The preset axis can extend along the thickness direction or the length direction of the earphone case 10, and no specific limitation is made here.

[0022] In some embodiments, the case body includes a case cover 11 and a main body 12. The case cover 11 is movably connected to the main body 12 and moves between a closed position and an open position relative to the main body 12; when the case cover 11 is in the closed position, it covers one side of the main body 12 along a preset direction. An accommodation groove 122 for accommodating the earphones is provided on one side of the main body 12, and the number of the accommodation grooves 122 can be the same as the number of the earphones. The accommodation groove 122 is used to accommodate the earphones. The case cover 11 is rotatably / slidably connected to the main body 12 for selectively covering the accommodation groove 122. For example, the case cover 11 is rotatably connected to the main body 12 through a rotating shaft 127 to achieve a flip - type design. For example, the case cover 11 can be slid relative to the main body 12 through the cooperation of a slide rail and a slider, thereby achieving a slide - cover type design.

[0023] On the basis of the previous embodiment, the knob 124 is disposed on the main body 12 and partially protrudes from the surface of the main body 12. Among them, the electronic control board of the earphone case 10 and its matching parts are all placed inside the main body 12. Setting the knob 124 on the main body 12 facilitates matching the knob 124 with the electronic control board. And during the use of the earphone case 10, the user generally holds the main body 12 and controls the case cover 11 to rotate relative to the main body 12. Setting the knob 124 on the main body 12 is also more stable. On the other hand, the volume of the main body 12 is larger than that of the case cover 11, and setting the knob 124 on the main body 12 is also more convenient for the user to operate the knob 124.

[0024] In some embodiments, the main body 12 includes a plurality of side walls, and the knob 124 is disposed at the connection of adjacent side walls. Considering the user's hand-holding habit, generally, the user holds the earphone by pinching it with, for example, the thumb and other fingers or holds it with the palm. In this case, the user's fingers are closer to the connection of adjacent side walls. By disposing the knob 124 at the connection of adjacent side walls, it is more in line with the usage habit and facilitates the operation of the knob 124.

[0025] Further, in some embodiments, the lid 11 is rotatably connected to one of the side walls of the main body 12, and the knob 124 is disposed at the connection of the side wall rotatably connected to the main body 12 and its adjacent side wall. When the lid 11 is rotatably connected to the main body 12, for the user, if the opening of the earphone case 10 is to be more convenient, the side wall connecting the main body 12 and the lid 11 should be relatively far from the user. In this case, when the user holds the earphone case 10, it is more convenient for the user to operate the knob 124 by disposing the knob 124 at the connection of the side wall rotatably connected to the main body 12 and its adjacent side wall. It should be noted that the foregoing is only an example of a more convenient usage mode of the earphone case 10. The description of the user's usage scenario is for facilitating the description of the effect of the solution, and should not be construed as a specific limitation on the technical solution of the present application, nor should it be construed that it must be used in the foregoing manner.

[0026] In some embodiments, the knob 124 has magnetism. In other embodiments, the earphone case 10 includes a magnet 1241, and the magnet 1241 is fixed to the knob 124 so as to be able to rotate with the knob 124. With such a setting, a Hall sensing member 125 is disposed in the earphone case 10 to be able to detect the rotation of the knob 124, so as to control the earphone assembly according to the rotation of the knob 124.

[0027] In some embodiments, in combination Figure 3 , the earphone case 10 includes a magnet 1241 and a Hall sensing member 125. The magnet 1241 is disposed on the knob 124 so as to be able to rotate with the knob 124. The Hall sensing member 125 is used to sense the rotation direction of the magnet 1241, and thus sense the rotation direction of the knob 124, so that different preset functions are realized by rotating the knob 124 in different rotation directions to control the earphone. The Hall sensing member 125 cooperates with the magnet 1241 to detect the operation input by the user received by the knob 124. The operation input by the user includes the rotation direction and the pressing direction, etc.

[0028] In some embodiments, the knob 124 is provided with a receiving groove along a preset axis (for reference, see the insertion groove 1273), and the magnet 1241 is received in the receiving groove. With this arrangement, the preset axis of rotation of the knob 124 passes through the magnet 1241. When the magnet 1241 rotates following the knob 124, the axis of rotation of the magnet 1241 passes through itself, which can reduce the displacement generated by the magnet 1241 during rotation. The magnetic field change of the magnet 1241 is relatively regular, facilitating the detection of the magnetic field change by the Hall sensor 125.

[0029] In some embodiments, the housing is provided with an installation cavity 123 and an opening communicating with the installation cavity 123. The knob 124 is disposed in the installation cavity 123, and a part of the knob 124 is located outside the housing through the opening. The knob 124 located in the installation cavity 123 can be received by the earphone case 10, thereby reducing the part of the knob 124 located outside the housing to reduce the protruding part outside the earphone case 10, which is convenient for the user to store. The knob 124 located in the installation cavity 123 can also be closer to the Hall sensor 125 or circuit components inside the housing, so as to facilitate the recognition of the rotation of the knob 124. The part of the knob 124 located outside the housing can be rotated or pressed by the user to achieve a preset function.

[0030] In some embodiments, the earphone case 10 includes a bracket 126 and a rotating shaft 127. The bracket 126 is fixedly disposed on the housing; the knob 124 is rotatably disposed on the bracket 126 through the rotating shaft 127. The bracket 126 can connect the knob 124 and the housing. The bracket 126 can be separately manufactured with various structures for cooperating with the knob 124, and then assembled with the housing.

[0031] Specifically, the bracket 126 is provided with an axis receiving groove 1261 and an installation groove 1262 that intersect and communicate with each other. The axis receiving groove 1261 can be used to receive the rotating shaft 127, and the installation groove 1262 can be used to receive the knob 124. The axis receiving groove 1261 extends along the direction of the preset axis. At least a part of the knob 124 is disposed in the installation groove 1262. One end of the rotating shaft 127 is rotatably received in the axis receiving groove 1261, and the other end is connected to the knob 124. When the knob 124 rotates around the preset axis, it can drive the rotating shaft 127 to rotate. The rotating shaft 127 disposed in the axis receiving groove 1261 can limit the free movement of the knob 124 to reduce the movement of the knob 124 relative to the bracket 126 other than rotating around the preset axis.

[0032] In some embodiments, the knob 124 is provided with an insertion groove 1273 along the preset axis, and the other end of the rotating shaft 127 is inserted into the insertion groove 1273 to be connected to the knob 124.

[0033] In some embodiments, the aforementioned receiving groove is equivalent to the insertion groove 1273. For example, one end of the rotating shaft 127 connected to the knob 124 extends into the receiving groove having the magnet 1241 to be connected to the knob 124. In this way, the receiving groove can also be sealed, and the magnet 1241 can be limited within the receiving groove.

[0034] In some embodiments, the earphone case 10 includes a damping ring 128. The damping ring 128 is sleeved on one end of the rotating shaft 127 and abuts against the bracket 126 and the rotating shaft 127 within the shaft receiving groove 1261, for providing rotational damping for the rotation of the rotating shaft 127 relative to the bracket 126. The damping force received by the rotating shaft 127 can be transmitted to the knob 124, so that when the user rotates the knob 124, the user can feel the effect of the damping force, which is convenient for the user to control the rotation of the knob 124 and reduces the uncontrolled rotation of the knob 124. Optionally, the damping ring 128 is detachably sleeved on one end of the rotating shaft 127. Optionally, a ring groove is formed at one end of the rotating shaft 127, and a part of the damping ring 128 is embedded in the ring groove. Optionally, the damping ring 128 is detachably sleeved on one end of the rotating shaft 127, and a ring groove is formed at one end of the rotating shaft 127, and a part of the damping ring 128 is embedded in the ring groove.

[0035] In some embodiments, the rotating shaft 127 includes a first shaft section 1271 and a second shaft section 1272, and the first shaft section 1271 and the second shaft section 1272 are connected to each other along a preset axis. The diameter of the first shaft section 1271 is larger than that of the second shaft section 1272, and a stepped surface is formed at the connection between the first shaft section 1271 and the second shaft section 1272. The first shaft section 1271 is received within the shaft receiving groove 1261, the second shaft section 1272 is received within the insertion groove 1273, and the stepped surface abuts against one side of the knob 124 facing the shaft receiving groove 1261. The first shaft section 1271 can be rotatably connected to the shaft receiving groove 1261, and the second shaft section 1272 can be fixedly connected to the insertion groove 1273 by interference fit, gluing or welding. The stepped surface of the first shaft section 1271 and the second shaft section 1272 can limit the movement of the knob 124 in the preset axis direction by abutting against the knob 124, making the connection between the knob 124 and the bracket 126 more stable.

[0036] In some embodiments, the bracket 126 further defines a limiting groove 1263 communicating with the mounting groove 1262. The limiting groove 1263 is disposed opposite to the shaft receiving groove 1261 on the preset rotation axis. A limiting portion 1242 protrudes along the preset axis on a side of the bracket 126 away from the shaft receiving groove 1261, and at least a part of the limiting portion 1242 is received within the limiting groove 1263, and the limiting portion 1242 is rotatably connected to the limiting groove 1263. The cooperation between the limiting portion 1242 and the limiting groove 1263 can, on the one hand, also function as the rotating shaft 127, and on the other hand, can also limit the degree of freedom of the knob 124 to limit other activities of the knob 124 except for rotation along the preset axis.

[0037] In some embodiments, the knob 124 can move relative to the box body in a direction perpendicular to the preset axis, that is, in the radial direction of the knob 124. The earphone box 10 includes a touch switch 129, which is disposed on the box body and corresponds to the position of the knob 124, and the touch switch 129 is fixed to the box body. The knob 124 can trigger the touch switch 129 to perform related operations by moving relative to the box body in a direction perpendicular to the preset axis. The touch switch 129 can be, for example, functions such as Bluetooth pairing or power-on, which are not specifically limited herein.

[0038] Further, the earphone box 10 includes a bracket 126, and the knob 124 is rotatably disposed on the bracket 126. For the specific description of the bracket 126, reference can be made to the above embodiments and will not be elaborated herein. The bracket 126 is movably disposed on the box body and can move relative to the box body in a direction perpendicular to the preset axis, for example, in a direction approaching or away from the touch switch 129. The bracket 126 can drive the knob 124 to move relative to the box body. In other words, when the knob 124 is rotated, the knob 124 rotates relative to the bracket 126 and the box body, while the bracket 126 remains stationary relative to the box body. When the knob 124 is pressed, the knob 124 can drive the bracket 126 to move relative to the box body to trigger the touch switch 129.

[0039] In some embodiments, the earphone box 10 includes a base 131, and the base 131 is fixedly disposed on the box body; the bracket 126 is slidably connected to the base 131, and the touch switch 129 is disposed on the base 131 or surrounded by the base 131.

[0040] In some embodiments, the earphone box 10 includes an elastic member 130. One end of the elastic member 130 is fixed to the box body, and the other end of the elastic member 130 abuts against the bracket 126. The elastic member 130 elastically supports the bracket 126 in a direction perpendicular to the preset axis, so that the bracket 126 compresses the elastic member 130 when moving in the direction of the touch switch 129. When the user presses the knob 124, the bracket 126 is driven to move towards the touch switch 129 and compress the elastic member 130. When the user no longer presses the knob 124, the elastic member 130 elastically returns to reset the bracket 126 and the knob 124. Among them, the elastic member 130 can be a spring, a spring sheet or elastic silica gel, etc., which are not specifically limited herein.

[0041] Further, in some embodiments, the elastic member 130 is arranged in a ring shape, surrounding the periphery of the tactile switch 129, and the bracket 126 abuts against one side of the elastic member 130. The bracket 126 is configured to abut against the elastic member 130 when moving closer to the tactile switch 129 in a direction perpendicular to the preset axis, so that a part of the knob 124 can press the tactile switch 129 through the inner space of the elastic member 130. In other embodiments, the elastic member 130 is arranged between the bracket 126 and the tactile switch 129. During the movement of the bracket 126, the elastic member 130 can be pushed to deform, and the elastic member 130 can abut against the tactile switch 129 through the deformation.

[0042] In some embodiments, the knob 124 moves between a first position and a second position relative to the box body in a direction perpendicular to the preset axis. When the knob 124 is in the first position, it is spaced apart from the tactile switch 129 (in combination with Figure 3 ), and when in the second position, it abuts against the tactile switch 129 to trigger the tactile switch 129 to perform related operations.

[0043] Further, the earphone box 10 includes a bracket 126, the knob 124 is rotatably arranged on the bracket 126, and the bracket 126 is movably arranged on the box body and can move relative to the box body in a direction perpendicular to the preset axis. The bracket 126 can move between a first position and a second position relative to the box body in a direction perpendicular to the preset axis. When the bracket 126 is in the first position, it is spaced apart from the tactile switch 129, and when in the second position, it abuts against the tactile switch 129 to trigger the tactile switch 129 to perform related operations.

[0044] In some embodiments, the earphone box 10 includes an elastic member 130. The elastic member 130 elastically supports the bracket 126 in a direction perpendicular to the preset axis, so that the bracket 126 compresses the elastic member 130 when moving towards the tactile switch 129 and abuts against the tactile switch 129 in the second position.

[0045] Specifically, the earphone box 10 includes a bracket 126 and an elastic member 130. The knob 124 is rotatably arranged on the bracket 126, and the bracket 126 is movably arranged on the box body. The elastic member 130 is located between the bracket 126 and the tactile switch 129. The bracket 126 can move between a first position and a second position relative to the box body in a direction perpendicular to the preset axis. When the bracket 126 is in the first position, the elastic member 130 is spaced apart from the tactile switch 129. During the movement of the bracket 126 from the first position to the second position, the bracket 126 can press the elastic member 130 to deform. When in the second position, the elastic member 130 or the bracket 126 abuts against the tactile switch 129.

[0046] In some embodiments, the earphone case 10 includes a Hall sensor 125. The Hall sensor 125 is fixed to the case body, and the knob 124 can rotate relative to the Hall sensor 125. The Hall sensor 125 is used to sense the rotation direction of the knob 124, so that the knob 124 can control the earphone to achieve different preset functions by rotating in different directions. It should be noted that the Hall sensor 125 senses the magnetic field of the knob 124 or the magnet 1241 installed therein. Taking the magnet 1241 as an example, for the Hall sensor 125 to sense the rotation of the knob 124, it is required that during the rotation of the knob 124, the magnetic field passing through the Hall sensor 125 changes.

[0047] In some embodiments, in combination with Figure 4 and Figure 5 , taking the installation of the magnet 1241 in the knob 124 as an example, the Hall sensor 125 is located on one side of the knob 124 along the direction of the preset axis. In this case, the sensing surface of the Hall sensor 125 can be arranged facing the knob 124, that is, facing the direction of the preset axis. The magnetic pole direction of the magnet 1241 can be set perpendicular to the preset axis. Optionally, the sensing surface of the Hall sensor 125 can be arranged parallel to the preset axis, and the magnetic pole direction of the magnet 1241 can be perpendicular to the preset axis. In the above cases, when the knob 124 drives the magnet 1241 to rotate, the magnetic field passing through the Hall sensor 125 can change, so that the Hall sensor 125 senses the rotation of the knob 124.

[0048] In some embodiments, in combination with Figure 6 and Figure 7 , the Hall sensor 125 is located on one side of the knob 124 along the direction perpendicular to the preset axis. In this case, the sensing surface of the Hall sensor 125 can be arranged facing the magnet 1241, and the magnetic pole direction of the magnet 1241 is also located along the direction perpendicular to the preset axis. Optionally, the sensing surface of the Hall sensor 125 can be arranged facing the direction of the preset axis, and the magnetic pole direction of the magnet 1241 is located along the direction perpendicular to the preset axis. In the above cases, when the knob 124 drives the magnet 1241 to rotate, the magnetic field passing through the Hall sensor 125 can change, so that the Hall sensor 125 senses the rotation of the knob 124.

[0049] In some embodiments, the bracket is further provided with a limiting groove 1263 connected to the mounting groove 1262, and the limiting groove 1263 is arranged opposite to the shaft receiving groove 1261 on a preset rotation axis. A limiting portion 1242 is protruded along the preset axis on one side of the bracket 126 away from the shaft receiving groove 1261, and at least part of the limiting portion 1242 is accommodated in the limiting groove 1263. The earphone box 10 includes a magnet 1241 and a Hall sensor 125, and the magnet 1241 is arranged on the knob 124 so as to rotate with the knob 124. The knob 124 is provided with an insertion groove 1273 along the preset axis, and the insertion groove 1273 extends into the limiting portion 1242. The other end of the rotating shaft 127 is inserted into the insertion groove 1273. The magnet 1241 is arranged in the insertion groove 1273, and is spaced apart from or abuts against the other end of the rotating shaft 127. The limiting groove 1263 further penetrates the side of the bracket 126 away from the shaft receiving groove 1261 along the preset axis. At least a portion of the Hall sensor 125 is disposed in the limiting groove 1263 and is disposed opposite to the limiting portion 1242 .

[0050] In some embodiments, the Hall sensor 125 includes a sensing portion 1251 and a mounting base 1252 . The sensing portion 1251 is disposed on the mounting base 1252 . The mounting base 1252 is located in the limiting groove 1263 and abuts against a side of the bracket 126 away from the shaft receiving groove 1261 .
