Description

Technical Field

[0001] This invention relates to the field of headphone case technology, and particularly to a headphone case and a wireless headphone assembly. Background Technology

[0002] In recent years, TWS (True Wireless Stereo) earphones have been rapidly emerging in the headphone market. They use Bluetooth chips to first establish a wireless connection between the main earphone and devices such as mobile phones, and then establish wireless communication between the main earphone and the secondary earphone, thus completely eliminating the wired connection between traditional earphones and greatly facilitating the user experience.

[0003] TWS earbuds typically come with a charging case for everyday storage and charging. Currently, most charging cases use a flip-top design for opening and closing, with a hinge and spring mechanism. However, once the case is open, the lid can easily rotate relative to the case body, and the lid occupies a significant amount of space on top of the case, making it inconvenient for users to remove or place the earbuds, thus impacting the user experience. Summary of the Invention

[0004] The main objective of this invention is to provide an earphone case that addresses the technical problem of existing earphone cases being inconvenient for users to take out and remove earphones.

[0005] To achieve the above objectives, the present invention provides an earphone case comprising:

[0006] The housing has a mounting shaft and a placement slot for placing electronic components.

[0007] A cover body, which is mounted on the box body and has a sleeve groove, which is sleeved on the mounting shaft;

[0008] A rotating mechanism is provided in the socket groove. The rotating mechanism connects the mounting shaft and the cover, so that the cover can rotate around the mounting shaft to selectively cover or expose the placement groove.

[0009] In some embodiments, the rotating mechanism includes:

[0010] The mounting component is coaxially connected to the mounting shaft, and a boss is formed on the side wall of the mounting component;

[0011] A snap-fit ​​component is sleeved on the mounting component and disposed opposite to the boss, for rotating with the cover and moving along the groove wall of the sleeve groove to approach or move away from the boss. One of the snap-fit ​​component and the boss is provided with a plurality of guide grooves arranged at intervals along its circumference, and the other is provided with at least one engaging part adapted to the guide groove. The guide groove has a guide surface that is inclined or arc-shaped, for discharging the engaging part when the cover rotates.

[0012] An elastic element, one end of which abuts against the snap-fit ​​element, and the other end abuts against the bottom wall of the sleeve groove.

[0013] In some embodiments, the guide surface includes a first guide surface for disengaging the engaging portion when the cover rotates in a first direction; and / or,

[0014] The guide surface includes a second guide surface for disengaging the engaging portion when the cover rotates in the second direction;

[0015] The second direction is opposite to the first direction.

[0016] In some embodiments, the engaging portion has a guide surface that aligns with the guide surface, for moving along the guide surface to disengage the engaging portion when the cover rotates.

[0017] In some embodiments, the number of slots is an integer multiple of the number of engaging portions.

[0018] In some embodiments, one of the snap-fit ​​member and the groove sidewall of the sleeve groove is provided with a sliding limiting portion, and the other is provided with a sliding groove. The sliding limiting portion and the sliding groove are slidably engaged to guide the snap-fit ​​member as it moves.

[0019] In some embodiments, one end face of the mounting member is provided with a shaft hole, and one end of the mounting shaft that passes through the sleeve groove is inserted into the shaft hole;

[0020] The bottom wall of the shaft hole is provided with a through hole that penetrates the other end face of the mounting member, and the mounting member is connected to the mounting shaft by fasteners passing through the through hole.

[0021] In some embodiments, the cover includes:

[0022] A rotating part, on which the sleeve groove is formed;

[0023] A shielding part is connected to the rotating part and extends radially outward from the rotating part, used to shield the placement slot or expose the placement slot.

[0024] In some embodiments, the placement slots are at least two, and the at least two placement slots are arranged at circumferential intervals along the box body;

[0025] The shielding part has at least two parts, and each shielding part corresponds to one placement slot.

[0026] The present invention also proposes a wireless earphone assembly, which includes earphones and an earphone case as described above, wherein the earphones are placed in the earphone case.

[0027] This invention relates to an earphone case that uses a screw-on lid opening mechanism. During use, rotating the lid around a mounting shaft on the case via a rotating mechanism exposes a slot on the case, thus opening the earphone case. The user can then remove or place electronic devices, such as earphones, from the slot. Conversely, rotating the lid around the mounting shaft again closes the slot, thus closing the earphone case. Compared to current flip-top opening mechanisms, this invention's earphone case opens by rotating the lid in place. After opening, the lid and case are less likely to rotate, and their spatial position on the case remains almost unchanged. This makes it convenient for the user to remove and place earphones, improving the user experience. Attached Figure Description

[0040] A wireless earphone assembly is a combination of an earphone case and wireless earphones. The wireless earphones typically include a left and a right wireless earphone. The earphones transmit audio from a device such as a mobile phone or tablet as a digital signal via Bluetooth. The earphone's decoder converts the digital signal into a waveform, which causes the voice coil to vibrate to varying degrees. The diaphragm vibrates, generating air waves, which are then perceived by the ear. The earphone case integrates earphone storage and charging functions, and can also be called an earphone storage case or earphone charging case. When the wireless earphones are not in use, they can be placed in the earphone case for storage; when needed, the earphones can be taken out of the case.

[0041] Reference Figures 1 to 7 The present invention provides an earphone case 100, which includes:

[0042] The box 110 is provided with a mounting shaft 111 and a placement groove 110a, the placement groove 110a being used to place electronic components;

[0043] The cover 120 is mounted on the box 110 and has a sleeve groove 120a, which is sleeved on the mounting shaft 111.

[0044] The rotating mechanism 130 is located in the socket groove 120a. The rotating mechanism 130 connects the mounting shaft 111 and the cover 120, so that the cover 120 can rotate around the mounting shaft 111 to selectively cover or expose the placement groove 110a.

[0045] like Figure 1 and Figure 2 As shown, the outer shape of the housing 110 can be a frustum, a hemisphere, or other shapes, depending on the actual situation. A placement slot 110a is formed on the outer surface of the housing 110 for placing electronic devices, including earphones 200. In addition, electronic devices can also include antenna transmitters, etc., without limitation. The following example uses placement slot 110a to hold earphones 200. As a conventional design, two placement slots 110a can be provided to accommodate a pair of earphones 200. This is merely an example and not a limitation. A mounting shaft 111 extends from the outer surface of the housing 110 where the placement slot 110a is formed. Optionally, the mounting shaft 111 is located on the central axis of the housing 110, and the placement slot 110a is located around the mounting shaft 111.

[0046] like Figure 1 and Figure 2 As shown, the cover 120 can be claw-shaped or other forms, depending on the actual situation. The cover 120 is mounted on the housing 110, located on the outer surface of the housing 110 where the placement groove 110a is formed. The bottom wall of the slot 120a of the cover 120 has a through-hole. The mounting shaft 111 of the housing 110 passes through the through-hole into the slot 120a. The cover 120 is fitted onto the mounting shaft 111 through its slot 120a and can rotate around it, thus covering or exposing the placement groove 110a during rotation around the mounting shaft 111, thereby closing or opening the housing. It is easy to understand that in the normally placed state of the headphone case 100, the cover 120 is on top, and the housing 110 is below, and the cover 120 on the housing 110 can rotate in the horizontal plane. The orthographic projection of the cover 120 is within the range of the orthographic projection of the housing 110. Optionally, the socket groove 120a is located on the central axis of the cover 120. When the cover 120 rotates about the mounting shaft 111, that is, it rotates about its own central axis, it can block the placement groove 110a in its rotation path, or expose the placement groove 110a that is currently blocked. The rotation direction of the cover 120 can be clockwise or counterclockwise, which can be set according to the actual situation.

[0047] The rotating mechanism 130 is located within the socket groove 120a, and is disposed between and connects the mounting shaft 111 and the cover 120, allowing the cover 120 to rotate around the mounting shaft 111. When the user does not apply any force to rotate the cover 120, the cover 120 remains stationary relative to the mounting shaft 111 under the action of the rotating mechanism 130. However, when the user applies a force to rotate the cover 120 beyond a preset value, the cover 120 rotates around the mounting shaft 111 under that force.

[0048] The headphone case 100 of the present invention adopts a screw-on lid opening and closing method. During use, the lid 120 is rotated around the mounting shaft 111 on the case 110 via the rotating mechanism 130, which exposes the placement slot 110a on the case 110, thereby opening the headphone case 100. The user can take out and put in electronic devices, such as headphones 200, from the placement slot 110a on the case 110. Correspondingly, the lid 120 is rotated around the mounting shaft 111 on the case 110 via the rotating mechanism 130, which covers the placement slot 110a on the case 110, thereby closing the headphone case 100.

[0049] Compared to the current flip-top opening and closing mechanism, the lid 120 of the earphone case 100 of this invention rotates in place to open. After the earphone case 100 is opened, the lid 120 and the case body 110 are not easily rotated and their spatial position on the case body 110 remains almost unchanged. This makes it convenient for users to take the earphones 200 out of the case body 110, which helps to improve the user experience.

[0050] In some embodiments, such as Figures 2 to 6 As shown, the rotating mechanism 130 includes:

[0051] Mounting component 131 is coaxially connected to mounting shaft 111, and a boss 1311 is constructed on the side wall of mounting component 131.

[0052] The snap-fit ​​component 132 is sleeved on the mounting component 131 and is disposed opposite to the boss 1311. It is used to rotate with the cover 120 and can move along the groove wall of the sleeve groove 120a to approach or move away from the boss 1311. One of the snap-fit ​​component 132 and the boss 1311 is provided with a plurality of guide grooves 1 arranged at intervals along its circumference, and the other is provided with at least one engaging part 2 adapted to the guide groove 1. The guide groove 1 has a guide surface 11 that is inclined or arc-shaped, which is used to guide the engaging part 2 out when the cover 120 rotates.

[0053] The elastic element 133 has one end abutting against the snap-fit ​​element 132 and the other end abutting against the bottom wall of the sleeve groove 120a.

[0054] Optionally, a guide groove 1 is provided on the boss 1311, and a locking part 2 is provided on the snap-fit ​​member 132. Taking this configuration as an example, when the cover 120 is in a static state, the locking part 2 on the snap-fit ​​member 132 is engaged in the guide groove 1 of the boss 1311 of the mounting member 131, and the rotating part 121 is stationary relative to the mounting shaft 111. When the cover 120 is rotated by an external force to open or close the box, the snap-fit ​​member 132 rotates with the rotating part 121 and slides away from the boss 1311 along the groove wall of the sleeve groove 120a. The elastic member 133 further accumulates elastic potential energy, and the locking part 2 gradually exits from the guide groove 1 where it is currently engaged. However, when the locking part 2 has not completely exited from the current guide groove 1 and the external force is suddenly removed, the locking part 2 will return to the guide groove 1 under the elastic force of the elastic member 133, and drive the cover 120 to rotate back to its original position and remain stationary.

[0055] When the engaging part 2 completely exits from the current guide groove 1 and reaches and passes the next guide groove 1 position, the elastic element 133 will automatically release its elastic potential energy. Under the action of the elastic force of the elastic element 133, the engaging part 132 slides along the groove wall of the sleeve groove 120a close to the boss 1311, and the engaging part 2 extends into the guide groove 1 to engage with it. The rotating part 121 remains stationary relative to the mounting shaft 111, that is, the cover 120 remains stationary again, realizing the opening or closing of the box.

[0056] Furthermore, when the lid 120 is rotated to open or close the box, the rotating part 121 drives the locking part 132 to rotate, and the locking part 2 can move quickly out along the guide surface 11 in the guide groove 1, improving the smoothness of the lid-turning operation and avoiding jamming. Optionally, the guide surface 11 is formed on the side wall of the guide groove 1, and the guide surface 11 can be an inclined surface or an arc surface, which can be set according to the actual situation.

[0057] The mounting component 131 is detachably mounted on the mounting shaft 111, and the connection method between the two can include screw connection, snap-fit, adhesive connection, etc., without limitation. Figure 4 and Figure 6 As shown, the boss 1311 is an annular boss that protrudes from the side wall of the mounting member 131. The number of guide grooves 1 on the boss 1311 is set according to the actual situation. Furthermore, the snap-fit ​​member 132 can be an annular structure, with the engaging part 2 protruding from one end of the snap-fit ​​member 132 and facing the end face of the boss 1311. The number of engaging parts 2 can be set according to the guide grooves 1 on the boss 1311, and can be set according to the actual situation.

[0058] like Figure 4 and Figure 6As shown, optionally, the elastic element 133 is a spring and is sleeved on the mounting member 131. The spring is located on the side of the snap-fit ​​member 132 away from the boss 1311. The spring maintains an elastic force on the snap-fit ​​member 132. When the snap-fit ​​member 132 slides away from the boss 1311 in the sleeve groove 120a, the spring is further compressed by the snap-fit ​​member 132 and relatively shortened. When the snap-fit ​​member 132 slides closer to the boss 1311 in the sleeve groove 120a, the spring is relatively extended.

[0059] Specifically, the mounting component 131, the snap-fit ​​component 132, and the elastic component 133 in the rotating mechanism 130, in conjunction with the bottom wall of the sleeve groove 120a, limit the cover 120 from detaching from the mounting shaft 111, thus achieving the installation limitation of the cover 120. Furthermore, the engagement portion 2 between the snap-fit ​​component 132 and the mounting component 131, in conjunction with the guide groove 1, enables the screw-on opening method, meeting users' personalized needs and enhancing product competitiveness. Moreover, the structural arrangement of the engagement portion 2 between the snap-fit ​​component 132 and the mounting component 131, the guide groove 1, and the elastic component 133 provides a damping feel when rotating the cover 120, improving the operating feel of the switch box and eliminating the need for additional damping components, thus saving costs.

[0060] Furthermore, such as Figure 6 As shown, the guide surface 11 includes a first guide surface 11a for disengaging the engaging portion 2 when the cover 120 rotates in a first direction; and / or, the guide surface 11 includes a second guide surface (not shown) for disengaging the engaging portion 2 when the cover 120 rotates in a second direction; wherein the second direction is opposite to the first direction.

[0061] Depending on the actual application, the rotation mode of the cover 120 can be set to allow only unidirectional rotation (in the first direction or the second direction) or bidirectional rotation (in both the first and second directions). The first direction can be clockwise or counterclockwise, and correspondingly, the second direction, which is opposite to the first direction, can be either clockwise or counterclockwise.

[0062] For example, the cover 120 is configured to rotate only in the first direction. In the first direction, the guide groove 1 is provided with a first guide surface 11a to guide the locking part 2 to move and guide it when the cover 120 rotates in the first direction, so that it exits the guide groove 1 in the first direction. In the second direction, the guide groove 1 is provided with a first limiting vertical surface 12 to prevent the locking part 2 from exiting the guide groove 1 in the second direction, thereby restricting the cover 120 from rotating in the second direction.

[0063] For example, the cover 120 is configured to rotate only in the second direction. In the second direction, the guide groove 1 is provided with a second guide surface to guide the engaging part 2 to move in the second direction when the cover 120 rotates in the second direction, so that it exits the guide groove 1 in the second direction. In the first direction, the guide groove 1 is provided with a second limiting vertical surface to prevent the engaging part 2 from exiting the guide groove 1 in the first direction, thereby restricting the cover 120 from rotating in the first direction.

[0064] For example, the cover 120 is configured to rotate in both a first direction and a second direction. In the first direction, the guide groove 1 is provided with a first guide surface 11a to guide the engaging part 2 to move and guide it when the cover 120 rotates in the first direction, so that it exits the guide groove 1 in the first direction. In the second direction, the guide groove 1 is provided with a second guide surface to guide the engaging part 2 to move and guide it when the cover 120 rotates in the second direction, so that it exits the guide groove 1 in the second direction.

[0065] In some embodiments, such as Figure 6 As shown, the engaging part 2 has an outlet surface 21 that aligns with the guide surface 11, and is used to move along the guide surface 11 to outlet the engaging part 2 when the cover 120 rotates.

[0066] When the cover 120 is rotated to open or close the box, the rotating part 121 drives the locking member 132 to rotate, and the outlet surface 21 of the engaging part 2 moves along the guide surface 11 of the guide groove 1, which allows the engaging part 2 to quickly exit the guide groove 1, further improving the outlet speed of the engaging part 2. In conjunction with the aforementioned embodiment, when the guide surface 11 of the guide groove 1 includes a first guide surface 11a, the outlet surface 21 of the engaging part 2 correspondingly includes a first outlet inclined surface 21a, and the first outlet inclined surface 21a is aligned and engaged with the first guide surface 11a; when the guide surface 11 of the guide groove 1 includes a second guide surface, the outlet inclined surface 21 of the engaging part 2 correspondingly includes a second outlet inclined surface, and the second outlet inclined surface is aligned and engaged with the second guide surface.

[0067] In some embodiments, the number of guide grooves 1 is an integer multiple of the number of engaging parts 2, n. Optionally, n is 1, 2, 3, ..., etc., set according to the actual situation.

[0068] The number of guide grooves 1 is set according to the rotation angle of the cover 120 switch box, and the number of guide grooves 1 is an integer multiple of the number of engaging parts 2. As an example, the cover 120 is set to rotate 60° to switch positions for opening or closing the box. Six guide grooves 1 can be set on the boss 1311, and the six guide grooves 1 are set at 60° intervals in the circumferential direction. That is, each time the cover 120 rotates 60°, the engaging part 2 on the latching member 132 exits from one guide groove 1 of the boss 1311 and rotates to engage with the next guide groove 1, so that the cover 120 can be kept stationary on the box again, corresponding to opening or closing the box. Optionally, corresponding to the six guide grooves 1 on the boss 1311, the engaging part 2 on the latching member 132 can be set to three, and the three engaging parts 2123a are set at 120° intervals in the circumferential direction, and the number of guide grooves 1 is twice that of engaging parts 2.

[0069] In some embodiments, such as Figure 6 and Figure 7 As shown, one of the slot sidewalls of the snap-fit ​​132 and the sleeve groove 120a is provided with a sliding limit part 3, and the other is provided with a sliding groove 4. The sliding limit part 3 and the sliding groove 4 are slidably engaged to guide the snap-fit ​​132 when it moves.

[0070] The slide groove 4 extends along the moving direction of the snap-fit ​​member 132, and the sliding limiting part 3 is inserted into the slide groove 4 and can move within the slide groove 4. Optionally, the snap-fit ​​member 132 is provided with the sliding limiting part 3, and the slide groove 4 is provided on the side wall of the sleeve groove 120a. The number of sets of sliding limiting parts 3 and slide grooves 4 can be set to one or more, depending on the actual situation. Optionally, three sets of sliding limiting parts 3 and slide grooves 4 are provided, and the three sets of sliding limiting parts 3 and slide grooves 4 are spaced 120° apart in the circumferential direction. Through the sliding engagement of the sliding limiting parts 3 and slide grooves 4, the snap-fit ​​member 132 can be rotated by the rotating part 121, and can also be guided to slide in the sleeve groove 120a.

[0071] Specifically, when the lid 120 is rotated to open or close the box, the rotating part 121 of the lid 120 rotates, and the locking member 132, because its sliding limiting part 3 is inserted into the slide groove 4, can rotate with the rotating part 121. Simultaneously, the engaging part 2 of the locking member 132 is disengaged from the guide groove 1 by the force of the guide groove 1, and then the locking member 132 slides along the slide groove 4 via the sliding limiting part 3 to move away from the boss 1311. When the lid 120 is rotated to open or close the box, the engaging part 2 of the locking member 132 reaches and passes the next guide groove 1 position. Under the elastic force of the elastic member 133, the locking member 132 slides along the slide groove 4 via the sliding limiting part 3 to approach the boss 1311, and the engaging part 2 correspondingly extends into the guide groove 1 and engages with it.

[0072] In some embodiments, such as Figure 4 and Figure 6 As shown, one end of the mounting part 131 is provided with a shaft hole, and the end of the mounting shaft 111 that passes through the sleeve groove 120a is inserted into the shaft hole;

[0073] The bottom wall of the shaft hole is constructed with a through hole that passes through the other end of the mounting member 131. The mounting member 131 is connected to the mounting shaft 111 by fastener 10 passing through the through hole.

[0074] The mounting component 131 and the mounting shaft 111 are connected by a fastener 10, optionally a screw. Specifically, the mounting component 131 is placed on the mounting shaft 111. One end of the mounting shaft 111, which passes through the socket groove 120a, is inserted into the shaft hole of the mounting component 131 and aligned with its through hole. The fastener 10 passes through the through hole of the mounting component 131. The end of the mounting shaft 111, which passes through the socket groove 120a, has a connecting hole adapted to the fastener 10. The fastener 10 extends into the connecting hole to form a threaded connection, thereby fastening the mounting component 131 to the mounting shaft 111. Optionally, a washer 20 is sandwiched between the fastener 10 and the mounting component 131.

[0075] Optionally, the cross-sectional shape of the end of the mounting shaft 111 that passes through the sleeve groove 120a and the shaft hole is non-circular, such as irregular or polygonal. In this way, the mounting part 131 cannot rotate relative to the mounting shaft 111, which can improve the installation stability of the mounting part 131.

[0076] In some embodiments, such as Figure 1 and Figure 2 The cover 120 includes:

[0077] Rotating part 121, on which a sleeve groove 120a is formed;

[0078] The shielding part 122 is connected to the rotating part 121 and extends radially outward from the rotating part 121, and is used to shield the placement groove 110a or expose the placement groove 110a.

[0079] The cover 120 has a rotating part 121 and a blocking part 122. A sleeve groove 120a is located on the rotating part 121. The rotating part 121 of the cover 120 is sleeved on the mounting shaft 111 of the box body 110, so as to rotate and engage with the mounting shaft 111 on the box body 110 through a rotating mechanism 130. Optionally, the rotating part 121 is located on the central axis of the cover 120. The blocking part 122 is integrally formed with the rotating part 121 and extends from the rotating part 121. When the rotating part 121 of the cover 120 rotates around the mounting shaft 111, it drives the blocking part 122 to rotate accordingly; when the rotating part 121 of the cover 120 is stationary relative to the mounting shaft 111, the blocking part 122 stops rotating accordingly. The blocking part 122 can be a linear (e.g., straight line, wavy line) structure, an arc structure, a bent structure, etc., and its shape is not limited and can be set according to the actual situation. As an example, such as Figure 1 As shown, the blocking part 122 includes an extension section 122a extending from the rotating part 121 and a bent section 122b connected to the extension section 122a. The bent section 122b is bent toward the housing 110 to align with the edge of the housing 110. Specifically, the placement slot 110a on the housing 110 is located on the rotation path of the blocking part 122. The rotating part 121 of the cover 120 rotates on the mounting shaft 111, and the blocking part 122 rotates accordingly to switch positions, thereby blocking or exposing the placement slot 110a on the housing 110. It is easy to understand that when the blocking part 122 blocks the placement slot 110a, if an earphone is placed in the placement slot 110a, the blocking part 122 constitutes a limit on the earphone, so that the earphone is fixedly placed in the placement slot 110a. When the blocking part 122 exposes the placement slot 110a, the earphone can be taken out or put in. The number of blocking parts 122 can be one or more, depending on the actual situation. Furthermore, the correspondence between the blocking parts 122 and the placement slots 110a can be varied. For example, one blocking part 122 may be used to block one placement slot 110a, or to block two placement slots 110a, or multiple blocking parts 122 may be used to block one placement slot 110a, etc. There is no limitation on this; it can be set according to the actual situation.

[0080] In some embodiments, such as Figure 1 and Figure 2 As shown, there are at least two placement slots 110a, which are arranged at intervals along the circumference of the box body 110; and there are at least two blocking portions 122, which are arranged around the rotating portion 121 and each blocking portion 122 corresponds to one placement slot 110a.

[0081] At least two placement slots 110a on the housing 110 are arranged circumferentially at intervals, that is, multiple placement slots 110a are arranged sequentially at intervals around the central axis of the housing 110, and the interval angle between any two adjacent placement slots 110a in the circumferential direction of the housing 110 is the same. At least two blocking portions 122 of the cover 120 are provided corresponding to at least two placement slots 110a of the housing 110, and each blocking portion 122 corresponds to one placement slot 110a, and the included angle between any two adjacent blocking portions 122 is the same. When the earphone case 100 is in the closed state, the at least two blocking portions 122 of the cover 120 block the at least two placement slots 110a on the housing 110, that is, each placement slot 110a is blocked by a blocking portion 122. By rotating the cover 120 to switch the position of each blocking part 122, at least two blocking parts 122 of the cover 120 are offset from at least two placement slots 110a on the case 110. Specifically, each blocking part 122 moves from the blocking position of the placement slot 110a to a position between two adjacent placement slots 110a, thereby offsetting the placement slots 110a so that the placement slots 110a are exposed and the headphone case 100 is in the open state.

[0082] For example, such as Figure 1 and Figure 2 As shown, the housing 110 has three placement slots 110a, which are arranged circumferentially around the housing 110, with adjacent slots 110a spaced 120° apart circumferentially. Specifically, two of the three slots 110a hold the earphone 200, and the remaining slot holds other electronic devices, such as an antenna transmitter. The cover 120 has three blocking portions 122, with an included angle of 120° between adjacent blocking portions 122. When the earphone case 100 is closed, the three blocking portions 122 of the cover 120 block the three placement slots 110a on the housing 110. By rotating the cover 120, the positions of the blocking parts 122 are switched. When the cover 120 is rotated 60° clockwise, the three blocking parts 122 of the cover 120 are offset from the three placement slots 110a on the case 110. Each blocking part 122 moves from a placement slot 110a to a position between two adjacent placement slots 110a, thereby offsetting the placement slots 110a so that the placement slots 110a are exposed, and the headphone case 100 is opened. It is easy to understand that when it is necessary to close the headphone case 100 again, the cover 120 is rotated 60° clockwise or 60° counterclockwise, and the three blocking parts 122 of the cover 120 will then block the three placement slots 110a on the case 110. The clockwise direction can be clockwise or counterclockwise, and the counterclockwise direction can be either clockwise or counterclockwise.

[0083] Optionally, a magnetic attraction component (not shown) is provided at the free end of the blocking part 122 (i.e., the end of the blocking part 122 away from the rotating part 121) and at the position corresponding to each placement slot 110a on the housing 110. The magnetic attraction component may include a magnet, a metal part that can be magnetically attracted, etc. In this way, through the magnetic attraction between the free end of the blocking part 122 and the magnetic attraction component of the housing 110, the headphone case 100 is more stable when closed, and a damping sensation is provided for rotating the cover 120 when opening the headphone case 100, which helps to improve the user experience.
