[0040] The wireless earphone assembly is a combination of an earphone box and a wireless earphone. The wireless earphone usually includes a left wireless earphone and a right wireless earphone. The wireless earphone transmits the sound of a mobile phone or a tablet in the form of a digital signal to the earphone through Bluetooth, and the decoder of the earphone converts the digital signal into a waveform, which makes the voice coil vibrate to different degrees, and the vibration of the diaphragm produces air waves, which are perceived by the ear. The earphone box integrates earphone storage, charging and other functions, and can also be called an earphone storage box, an earphone charging box, etc. When the wireless earphone is not used, it can be placed in the earphone box for storage; when the wireless earphone is needed, the earphone box can be opened and the wireless earphone can be taken out from the earphone box.

[0041] Reference Figures 1 to 4The earphone box 100 comprises:

[0042] The box body 110 is provided with a mounting shaft 111, a placing groove 110a and a containing cavity 110b, the placing groove 110a is used for placing electronic devices;

[0043] The cover body 120 is mounted on the box body 110 and is provided with a sleeving groove 120a, the sleeving groove 120a is sleeved on the mounting shaft 111, and the cover body 120 can rotate around the mounting shaft 111 to selectively shield or expose the placing groove 110a;

[0044] The opening and closing detection mechanism 130 is used for detecting the opening and closing state of the earphone box 100, and comprises a detection piece 131, a touching piece 132, an extrusion piece 133 and an elastic piece 134, the detection piece 131 is located in the box body 110, the touching piece 132 is movably arranged in the containing cavity 110b, the extrusion piece 133 is located in the containing cavity 110b, the extrusion piece 133 is connected to the cover body 120 and can rotate with the cover body 120 to extrude the touching piece 132, so that the touching piece 132 moves towards the detection piece 131, one end of the elastic piece 134 abuts against the touching piece 132, and the other end abuts against the cavity bottom wall of the containing cavity 110b.

[0045] As shown in Figure 1 and Figure 2 , the outer shape of the box body 110 can be a truncated cone, a hemisphere or other shapes, which can be set according to actual conditions. The placing groove 110a is formed on the outer surface of the box body 110 and is used for placing electronic devices, and the electronic devices comprise earphones 200. In addition, the electronic devices can also be an antenna transmitter and the like, which is not limited. Hereinafter, the placing groove 110a is taken as an example for placing the earphones 200, as a conventional design, two placing grooves 110a can be provided for placing a pair of earphones 200, which is only exemplary and not limited. The mounting shaft 111 penetrates out of the outer surface of the box body 110 where the placing groove 110a is formed, and optionally, the mounting shaft 111 is located on the central axis of the box body 110, and the placing groove 110a is located on the circumferential side of the mounting shaft 111.

[0046] As shown in Figure 1 and Figure 2As shown, the outer shape of the cover 120 can be claw-shaped or other shapes, which can be set according to actual conditions. The cover 120 is mounted on the box body 110 and located on the outer surface of the box body 110 where the placing groove 110a is formed. The bottom wall of the sleeve groove 120a of the cover 120 is provided with a shaft passing hole, and the mounting shaft 111 of the box body 110 penetrates into the sleeve groove 120a from the shaft passing hole. The cover 120 is sleeved on the mounting shaft 111 through the sleeve groove 120a and can rotate around the mounting shaft 111 to shield or expose the placing groove 110a during rotation around the mounting shaft 111, thereby closing or opening the earphone box. It is easy to understand that in the normal placing state, the earphone box 100 has the cover 120 on the top and the box body 110 on the bottom, and the cover 120 on the box body 110 can rotate in the horizontal plane. Among them, the orthographic projection of the cover 120 is located within the orthographic projection of the box body 110. Alternatively, the sleeve groove 120a is located on the central axis of the cover 120. When the cover 120 rotates around the mounting shaft 111, i.e., rotates around its own central axis, it can shield the placing groove 110a in its rotation path or expose the currently shielded placing groove 110a. The rotation direction of the cover 120 can be clockwise or counterclockwise, which can be set according to actual conditions.

[0047] The opening and closing detection mechanism 130 is used to detect the opening and closing state of the earphone box 100, wherein the opening and closing detection mechanism 130 includes a detection piece 131, a touching piece 132, a pressing piece 133 and an elastic piece 134, which corresponds to a contact type earphone box detection. Specifically, when the cover 120 rotates relative to the box body 110, the pressing piece 133 rotates with the cover 120 to press the touching piece 132 to selectively trigger the detection piece 131, so that the detection piece 131 outputs an opening or closing detection signal when the placing groove 110a of the box body 110 is exposed or shielded. For example, when the cover 120 is rotated to open the earphone box, the pressing piece 133 presses the touching piece 132 to move towards the trigger part of the detection piece 131. When the cover 120 is rotated to the opening position, the touching piece 132 corresponds to the trigger part of the detection piece 131, thereby triggering the detection piece 131. The detection piece 131 immediately outputs an opening detection signal to confirm that the earphone box is switched to an open state. When the cover 120 is rotated to close the earphone box, the pressing piece 133 releases the touching piece 132. Under the action of the elastic force of the elastic piece 134, the touching piece 132 moves away from the trigger part of the detection piece 131. When the cover 120 is rotated to the closing position, the touching piece 132 is separated from the trigger part of the detection piece 131. The detection piece 131 immediately outputs a closing detection signal to confirm that the earphone box is switched to a closed state.

[0048] The detection piece 131 can adopt a micro switch. The micro switch has a compact internal structure, a small gap between contacts, and can quickly transmit force to act and realize high sensitivity and precision detection, while having a long service life and high reliability. The extrusion piece 133 can have a ring structure and pass through the mounting shaft 111. The extrusion piece 133 can be inserted and fitted with the cover 120 in the axial direction. Specifically, as shown in Figure 6 and Figure 7 The cover 120 is provided with a first insertion groove 121a at one end thereof, and the extrusion piece 133 is provided with a first insertion part 133a matched with the first insertion groove 121a. The first insertion part 133a is inserted into the first insertion groove 121a, so that the extrusion piece 133 is fixed relative to the box body 120 in the rotating direction and can rotate with the box body 120. Optionally, the elastic piece 134 is a spring.

[0049] The earphone box 100 adopts a switch box mode of a rotating cover. During use, the earphone box 100 can be opened by rotating the cover 120 around the mounting shaft 111 on the box body 110, and the user can take and place electronic devices such as the earphone 200 from the placing groove 110a of the box body 110. Correspondingly, the earphone box 100 can be closed by rotating the cover 120 around the mounting shaft 111 on the box body 110. The opening and closing detection mechanism 130 detects the opening and closing state of the earphone box 100. The opening and closing detection mechanism 130 detects by the cooperation of the detection piece 131, the touching piece 132, the extrusion piece 133, and the elastic piece 134. Compared with the current non-contact Hall element and magnet cooperation detection mode, the detection cost is reduced, the detection is more accurate, and the detection stability is improved.

[0050] In some embodiments, referring to Figure 5 and Figure 6 The extrusion piece 133 has an extrusion surface 1331 abutting against the touching piece 132. The extrusion surface 1331 is provided with a plurality of grooves 1331a arranged at intervals in the circumferential direction. The groove wall surface of the groove 1331a has a slope or an arc surface.

[0051] Specifically, in the normal placement state, the cover 120, the extrusion piece 133, the touching piece 132, and the detection piece 131 are arranged in sequence in the vertical direction. One end of the touching piece 132 faces the extrusion piece 133, and the other end of the touching piece 132 faces the trigger part of the detection piece 131. The touching piece 132 can move vertically. The extrusion piece 133 can extrude one end of the touching piece 132 through the extrusion surface 1331, so that the touching piece 132 moves towards the trigger part of the detection piece 131, and the other end of the touching piece 132 contacts the trigger part of the detection piece 131. As shown in Figure 6As shown, in the circumferential direction of the extrusion piece 133, the extrusion surface 1331 has a plurality of grooves 1331a, the plurality of grooves 1331a are sequentially and spacedly arranged, and the interval angle between each adjacent groove 1331a is the same, and a convex part 1331b is formed between any two adjacent grooves 1331a. Among them, the groove wall surface of the groove 1331a is a slope or an arc surface, which is used for guiding in and / or guiding out the touch piece 132. When the cover 120 is rotated to open or close the box, the extrusion piece 133 rotates with it, the position of the extrusion surface 1331 of the extrusion piece 133 relative to the touch piece 132 changes, when the groove 1331a of the extrusion surface 1331 rotates to the position of the touch piece 132, the corresponding touch piece 132 is released, and the elastic force of the elastic piece 134 makes the touch piece 132 move upward to make it away from the trigger part of the detection piece 131; when the convex part 1331b of the extrusion surface 1331 rotates to the position of the touch piece 132, the corresponding touch piece 132 is extruded to move downward to make it contact the trigger part of the detection piece 131, and then trigger the detection piece 131.

[0052] Among them, the number of grooves 1331a arranged on the extrusion surface 1331 is related to the rotation angle of the cover 120 when opening or closing the box, which can be set according to the actual situation. For example, when the cover 120 is rotated by 60° to open or close the box, three grooves 1331a are arranged on the extrusion surface 1331 in the circumferential direction of the extrusion piece 133, and the three grooves 1331a are sequentially and spacedly arranged.

[0053] In some embodiments, referring to Figure 2 , Figure 4 , Figure 7 and Figure 8 , the opening and closing detection mechanism 130 further comprises:

[0054] The receiving piece 135 is arranged in the accommodating cavity 110b, and the extrusion piece 133 is carried on the receiving piece 135 and can rotate along the receiving surface of the receiving piece 135;

[0055] Among them, the receiving surface of the receiving piece 135 and one of the extrusion pieces 133 are provided with a plurality of circumferentially spaced guide grooves 1, and the other is provided with at least one positioning part 2 matched with the guide groove 1, and the guide groove 1 has a guide surface 11 which is a slope or an arc surface, which is used for guiding the positioning part 2 out when the cover 120 rotates.

[0056] The receiving piece 135 can be a ring structure to cooperate with the extrusion piece 133 to realize the opening and closing positioning of the earphone box 100. Among them, the receiving piece 135 can be inserted and matched with the box body 110, specifically, as Figure 7 and Figure 8As shown, the receiving member 135 is provided with a second insertion part 135a at one end thereof, and the box body 110 is provided with a second insertion slot 110c, the second insertion part 135a is matched with the second insertion slot 110c and is inserted into the second insertion slot 110c, so that the receiving member 135 is fixed on the box body 110.

[0057] When the cover body 120 is rotated to open or close the earphone box 100, the extrusion member 133 rotates with the cover body 120, and then rotates along the receiving surface of the receiving member 135, and the positioning part 2 exits from the current guide slot 1 and is clamped into the next guide slot 1. It is easy to understand that when the earphone box 100 is in an open state or a closed state, the positioning part 2 is clamped into the guide slot 1 to limit the rotation of the extrusion member 133 and the cover body 120, and the cover body 120 remains stationary relative to the box body 110 without being subjected to external forces such as artificial rotation. The number of guide slots 1 is related to the rotation angle of the cover body 120 when opening or closing the earphone box 100, and can be set according to actual conditions. For example, when the cover body 120 is rotated by 60° to open or close the earphone box 100, six guide slots 1 are correspondingly provided.

[0058] Further, during the rotation of the cover body 120, the cover body 120 drives the extrusion member 133 to rotate, and the positioning part 2 can quickly move out along the guide surface 11 in the guide slot 1, thereby improving the smoothness of the cover rotation operation and avoiding the occurrence of jamming. Alternatively, the guide surface 11 is formed on the side wall of the guide slot 1, and the guide surface 11 can be an inclined surface or an arc surface, which can be set according to actual conditions.

[0059] Alternatively, the receiving member 135 is provided with the guide slot 1, and the extrusion member 133 is provided with the positioning part 2. Further, the positioning part 2 is protruded on the outer side surface of the extrusion member 133, and the receiving member 135 is sleeved outside the extrusion member 133. Alternatively, the number of guide slots 1 is the same as that of the positioning parts 2, and each positioning part 2 is clamped into a guide slot 1, and the positioning stability of the earphone box 100 when opening or closing the earphone box 100 can be improved by one-to-one clamping and positioning of the plurality of positioning parts 2 and the plurality of guide slots 1.

[0060] In some embodiments, with reference to Figure 7 , the guide surface 11 includes a first guide surface 11a for guiding the positioning part 2 out when the cover body 120 is rotated in a first direction; and / or the guide surface 11 includes a second guide surface 11b for guiding the positioning part 2 out when the cover body 120 is rotated in a second direction.

[0061] According to actual application conditions, the rotation form of the cover body 120 can be set to be unidirectional rotation (in the first direction or the second direction) or bidirectional rotation (in the first direction and the second direction). The first direction can be the clockwise direction or the counterclockwise direction, and correspondingly, the second direction opposite to the first direction can be the counterclockwise direction or the clockwise direction.

[0062] For example, the cover 120 is arranged to be rotatable only in the first direction. In the first direction, the guide groove 1 is correspondingly provided with the first guide surface 11a to guide the movement of the positioning part 2 and make it exit the guide groove 1 in the first direction when the cover 120 is rotated in the first direction. In the second direction, the guide groove 1 is correspondingly provided with the limiting vertical surface to block the positioning part 2 from exiting the guide groove 1 in the second direction, thereby limiting the rotation of the cover 120 in the second direction.

[0063] For another example, the cover 120 is arranged to be rotatable only in the second direction. In the second direction, the guide groove 1 is correspondingly provided with the second guide surface 11b to guide the movement of the positioning part 2 and make it exit the guide groove 1 in the second direction when the cover 120 is rotated in the second direction. In the first direction, the guide groove 1 is correspondingly provided with the limiting vertical surface to block the positioning part 2 from exiting the guide groove 1 in the first direction, thereby limiting the rotation of the cover 120 in the first direction.

[0064] For yet another example, the cover 120 is arranged to be rotatable in both the first direction and the second direction. In the first direction, the guide groove 1 is correspondingly provided with the first guide surface 11a to guide the movement of the positioning part 2 and make it exit the guide groove 1 in the first direction when the cover 120 is rotated in the first direction. In the second direction, the guide groove 1 is correspondingly provided with the second guide surface 11b to guide the movement of the positioning part 2 and make it exit the guide groove 1 in the second direction when the cover 120 is rotated in the second direction.

[0065] In some embodiments, referring to Figure 7 , the positioning part 2 has a guide-out surface 21 that is in position cooperation with the guide surface 11 to move along the guide surface 11 to guide out the positioning part 2 when the cover 120 is rotated.

[0066] When the cover 120 is rotated to open or close the box, the cover 120 drives the pressing piece 133 to rotate, and the guide-out surface 21 of the positioning part 2 moves correspondingly along the guide surface 11 of the guide groove 1, so that the positioning part 2 can be quickly guided out of the guide groove 1, further improving the guide-out speed of the positioning part 2. In combination with the foregoing embodiments, when the guide surface 11 of the guide groove 1 includes the first guide surface 11a, the guide-out surface 21 of the positioning part 2 correspondingly includes the first guide-out surface 21a that is in position cooperation with the first guide surface 11a. When the guide surface 11 of the guide groove 1 includes the second guide surface 11b, the guide-out surface 21 of the positioning part 2 correspondingly includes the second guide-out surface 21b that is in position cooperation with the second guide surface 11b.

[0067] In some embodiments, referring to Figures 2 to 4 , Figure 8 , the box body 110 includes an outer shell 1101, a lower inner shell 1102, and an upper inner shell 1103, the lower inner shell 1102 is assembled to the outer shell 1101, and the upper inner shell 1103 is arranged on the lower inner shell 1102.

[0068] The accommodating cavity 110b includes a first cavity 110b1 and a second cavity 110b2 in communication, the first cavity 110b1 is configured on the upper inner shell 1103 and the extrusion piece 133 and the receiving piece 135 are located in the first cavity 110b1, and the second cavity 110b2 is configured on the lower inner shell 1102 and the contact piece 132 and the elastic piece 134 are located in the second cavity 110b2.

[0069] The box body 110 includes the structure of the outer shell 1101, the lower inner shell 1102 and the upper inner shell 1103, the lower inner shell 1102 is assembled with the outer shell 1101 to form an internal cavity to accommodate electronic devices such as a circuit board and a battery, and the upper inner shell 1103 is arranged on the lower inner shell 1102 in abutment. Among them, the outer shell 1101, the lower inner shell 1102 and the upper inner shell 1103 can be connected by buckle connection, screw connection, etc. to facilitate disassembly. The accommodating cavity 110b is divided into the first cavity 110b1 and the second cavity 110b2, and the first cavity 110b1 and the second cavity 110b2 are respectively configured on the upper inner shell 1103 and the lower inner shell 1102. When the upper inner shell 1103 is arranged on the lower inner shell 1102 in abutment, the first cavity 110b1 and the second cavity 110b2 are in communication. The opening and closing detection mechanism 130 is correspondingly divided into two parts to be respectively installed in the first cavity 110b1 and the second cavity 110b2 of the accommodating cavity 110b, and the cavity shapes of the first cavity 110b1 and the second cavity 110b2 are different. Among them, the extrusion piece 133 and the receiving piece 135 are installed in the first cavity 110b1 as a part, and the contact piece 132 and the elastic piece 134 are installed in the second cavity 110b2 as another part.

[0070] In some embodiments, referring to Figure 4 and Figure 5 One end of the contact piece 132 is configured with a boss 1321 extending radially therefrom, the boss 1321 is provided with a lug portion 1321a abutting against the extrusion surface 1331 of the extrusion piece 133, and the other end of the contact piece 132 penetrates the cavity bottom wall of the second cavity 110b2 for triggering the trigger portion of the contact detection piece;

[0071] The elastic piece 134 is sleeved on the contact piece 132, and one end of the elastic piece 134 abuts against the boss 1321 and the other end abuts against the cavity bottom wall of the second cavity 110b2.

[0072] During the rotation of the cover body 120, the pressing surface 1331 of the pressing member 133 changes the position relative to the contact member 132. When the convex position 1331b of the pressing surface 1331 rotates to the position of the contact member 132, the lug portion 1321a of the convex position 1321 of the contact member 132 is pressed, so that the contact member 132 moves downward, the other end of the contact member 132 is in contact with the triggering portion of the detection member 131, and then the detection member 131 is triggered. At the same time, the elastic member 134 is further compressed by the convex position 1321 to accumulate elastic potential energy; when the concave position 1341a of the pressing surface 1331 rotates to the position of the contact member 132, the lug portion 1321a of the convex position 1321 of the contact member 132 is released, and the elastic force of the elastic member 134 makes the contact member 132 move upward, and the other end of the contact member 132 is separated from the triggering portion of the detection member 131.

[0073] In some embodiments, referring to Figure 4 and Figure 5 , the convex position 1321 is provided with a sliding portion 3 on one of the cavity side walls of the second cavity 110b2, and a sliding groove 4 is provided on the other cavity side wall, and the sliding portion 3 and the sliding groove 4 are slidingly matched to guide the movement of the contact member 132.

[0074] Specifically, the sliding groove 4 is arranged in the vertical direction, and the sliding portion 3 is inserted into the sliding groove 4 and can move in the sliding groove 4. When the contact member 132 moves in the second cavity 110b2, the sliding portion 3 moves along the sliding groove 4, thereby guiding the movement of the contact member 132 and improving the stability of the movement of the contact member 132. The guiding structure of the sliding portion 3 and the sliding groove 4 can be one or more, which can be set according to the actual situation. Optionally, the sliding portion 3 is arranged on the convex position 1321, and the sliding groove 4 is arranged on the cavity side wall of the second cavity. Moreover, the sliding portion 3 and the sliding groove 4 are arranged one by one.

[0075] In some embodiments, referring to Figure 1 and Figure 2 , the cover body 120 comprises:

[0076] a rotating portion 121, the rotating portion 121 is formed with a sleeve slot 120a;

[0077] a shielding portion 122, the shielding portion 122 is connected to the rotating portion 121 and extends radially outward from the rotating portion 121, and is used for shielding or exposing the placement groove 110a.

[0078] The cover 120 has a rotating part 121 and a shielding part 122, and a sleeving groove 120a is arranged on the rotating part 121. The rotating part 121 of the cover 120 is sleeved on the mounting shaft 111 of the box 110 to be rotationally matched with the mounting shaft 111 on the box 110 through the rotating mechanism 130. Optionally, the rotating part 121 is located on the central axis of the cover 120. The shielding part 122 is integrally formed with the rotating part 121, and the shielding part 122 extends from the rotating part 121. When the rotating part 121 of the cover 120 rotates around the mounting shaft 111, the shielding part 122 is correspondingly rotated; when the rotating part 121 of the cover 120 is stationary relative to the mounting shaft 111, the shielding part 122 is correspondingly stopped. The shielding part 122 can be a linear (such as a straight line, a wavy line) structure, an arc structure, a bent structure, etc., and the outer shape is not limited and can be set according to actual conditions.

[0079] As an example, as shown in Figure 1 The shielding part 122 includes an extension segment 122a extending from the rotating part 121 and a bent segment 122b connected with the extension segment 122a, and the bent segment 122b is bent towards the box 110 to be matched with the edge position of the box 110. Specifically, the placing groove 110a on the box 110 is located on the rotating path of the shielding part 122, the rotating part 121 of the cover 120 rotates on the mounting shaft 111, the shielding part 122 is correspondingly rotated to switch positions, and then the placing groove 110a on the box 110 is shielded or exposed. It is easy to understand that when the shielding part 122 shields the placing groove 110a, if the earphone is placed in the placing groove 110a, the shielding part 122 constitutes a limit for the earphone, so that the earphone is fixedly placed in the placing groove 110a, and when the shielding part 122 exposes the placing groove 110a, the earphone can be taken out.

[0080] The number of the shielding part 122 can be one or more, which is set according to actual conditions. Moreover, the corresponding relationship between the shielding part 122 and the placing groove 110a can be various, for example, one shielding part 122 is used to shield one placing groove 110a, or is used to shield two placing grooves 110a, for example, a plurality of shielding parts 122 are used to shield one placing groove 110a, etc., which is not limited and is set according to actual conditions.

[0081] Further, as shown in Figure 1 and Figure 2As shown, the placement slots 110a are at least two, the at least two placement slots 110a are arranged along the circumference of the box body 110; and the shielding portions 122 are at least two, the at least two shielding portions 122 are arranged around the rotating portion 121 and each shielding portion 122 corresponds to one placement slot 110a. The at least two placement slots 110a on the box body 110 are arranged along the circumference thereof, that is, the plurality of placement slots 110a are sequentially arranged at intervals around the central axis of the box body 110, and the interval angle of any two adjacent placement slots 110a in the circumferential direction of the box body 110 is the same. The at least two shielding portions 122 of the cover body 120 correspond to the at least two placement slots 110a of the box body 110, and each shielding portion 122 corresponds to one placement slot 110a, and the included angle between any two adjacent shielding portions 122 is the same. When the earphone box 100 is in the closed state, the at least two shielding portions 122 of the cover body 120 correspond to the at least two placement slots 110a on the box body 110, that is, each placement slot 110a is shielded by one shielding portion 122. By rotating the cover body 120 to switch the positions of the shielding portions 122, at this time, the at least two shielding portions 122 of the cover body 120 correspond to the at least two placement slots 110a on the box body 110, that is, each shielding portion 122 corresponds to the position between the two adjacent placement slots 110a from the shielding position of the placement slot 110a, thereby staggering the placement slots 110a to expose the placement slots 110a, and the earphone box 100 is in the open state.

[0082] Exemplarily, as Figure 1 and Figure 2As shown, the placing slots 110a on the box body 110 have three, three placing slots 110a are arranged along the circumference of the box body 110, and the adjacent placing slots 110a are arranged at an interval of 120° in the circumferential direction of the box body 110. Specifically, two of the three placing slots 110a respectively place the earphone 200, and the other placing slot 110a places other electronic devices, such as an antenna transmitter. The shielding portions 122 on the cover body 120 have three, and the included angle between the adjacent shielding portions 122 is 120°. When the earphone box 100 is in the closed state, the three shielding portions 122 of the cover body 120 correspond to the three placing slots 110a on the box body 110. By rotating the cover body 120 to switch the positions of the shielding portions 122, when the cover body 120 is rotated by 60° in the forward direction, the three shielding portions 122 of the cover body 120 correspond to the three placing slots 110a on the box body 110, and each shielding portion 122 corresponds to moving from the placing slot 110a to the position between the adjacent two placing slots 110a, thereby misplacing the placing slots 110a to expose the placing slots 110a, and the earphone box 100 is opened. It is easy to understand that when it is necessary to close the earphone box 100 again, the cover body 120 is continuously rotated by 60° in the forward direction or in the reverse direction, and the three shielding portions 122 of the cover body 120 will correspond to the three placing slots 110a on the box body 110. Among them, the forward direction can be the clockwise direction or the counterclockwise direction, and correspondingly, the reverse direction can be the counterclockwise direction or the clockwise direction.

[0083] Optionally, the free end of the shielding portion 122 (that is, the end of the shielding portion 122 away from the rotating portion 121) is provided with a magnetic attraction component (not shown) at a position corresponding to each placing slot 110a on the box body 110. The magnetic attraction component can include a magnet, a metal piece that can be magnetically attracted, etc. In this way, through the magnetic attraction between the free end of the shielding portion 122 and the magnetic attraction component on the box body 110, the earphone box 100 is more stable when it is in the closed state, and can provide damping feeling when the cover body 120 is rotated to open the earphone box 100, which helps to improve the user's experience.

[0084] The present application also proposes a wireless earphone assembly, referring to Figure 9 The wireless earphone assembly includes an earphone box 100 and an earphone 200 placed in the earphone box 100, and the earphone box 100 is the earphone box 100 as described in the foregoing embodiments.
