Earphone box and earphone assembly

Abstract

The application discloses an earphone box and an earphone assembly. The earphone box comprises a box body, two cover bodies and an ejection mechanism. The opposite ends of the box body are respectively provided with independent earphone compartments. The two cover bodies are movably connected to the two ends of the box body respectively to correspond to the closing or opening of the two earphone compartments. The ejection mechanism is movably arranged on the box body and is in transmission connection with the two cover bodies. The cover body at any one end can move relative to the box body under the action of external force to drive the ejection mechanism to eject the earphone in the earphone compartment at the other end from the corresponding earphone compartment. When the earphone needs to be taken out, the cover body at any one end can be driven to move relative to the box body, so that the ejection mechanism ejects the earphone in the earphone compartment at the other end from the corresponding earphone compartment, which is convenient for the user to take, and meanwhile, the earphone compartment where the other unused earphone is located is not opened, so that the risk of losing the earphone can be reduced.

Technical Field

[0001] This invention relates to the field of electronic technology, and in particular to an earphone case and earphone assembly. Background Technology

[0002] As people's living standards improve, TWS (True Wireless Stereo) earphones are becoming increasingly popular.

[0003] In related technologies, TWS earbuds are usually packaged in pairs in an earbud case, with the left and right earbuds in the same compartment. When one earbud needs to be used independently, the lid of the earbud case where both earbuds are located still needs to be opened. This frequent opening and closing of the earbud case can easily lead to the risk of losing unused earbuds. Summary of the Invention

[0019] Rotation of the cover at either end can drive two transmission components to move along the corresponding guide grooves, thereby causing the protrusion at the other end to move closer to or away from the corresponding opening.

[0020] In one embodiment, the guide groove is an annular groove; the transmission component includes:

[0021] The outer sleeve is fitted onto the outside of the box body, and the end of the outer sleeve away from the elastic connector is abutted and connected to the cover body.

[0022] An inner sleeve, spaced apart within the outer sleeve, and slidably fitted within a guide groove, with a protrusion located at the end of the inner sleeve opposite to the elastic connector; and

[0026] The ejection mechanism is installed on the fixed part, and the two covers are separably fitted onto the outside of the two mounting parts; when the covers are fitted onto the mounting parts, the covers can rotate relative to the mounting parts and drive the ejection mechanism to move.

[0027] In one embodiment, when the cover is fitted onto the mounting part, the cover and the mounting part are interference-fitted, and the end of the cover abuts against the end of the fixing part.

[0028] In one embodiment, the end of the cover is abutted against both ends of the ejection mechanism.

[0029] In one embodiment, the projections of the two earphone compartments onto the longitudinal section of the housing are centrally symmetrical.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0052] This invention proposes an earphone case for storing TWS earphones. The design aims to allow users to open only the earphone compartment for the earphone they need to use when they need to use an earphone independently, without having to open both earphone compartments. This reduces the risk of losing the earphones and also reduces the size of the earphone case.

[0053] In embodiments of the present invention, such as Figures 1 to 7 As shown, the headphone case includes a case body 100, two covers 200, and an ejection mechanism 300.

[0054] The housing 100 has independent earphone compartments 101 at opposite ends; two covers 200 are movably connected to the two ends of the housing 100 to seal or open the two earphone compartments 101 respectively; an ejection mechanism 300 is movably disposed on the housing 100 and is connected to the two covers 200 in a transmission manner; wherein, the cover 200 at either end can move relative to the housing 100 under the action of an external force to drive the ejection mechanism 300 to eject the earphones in the earphone compartment 101 at the other end from the corresponding earphone compartment 101.

[0055] Understandably, the housing 100 serves to support and secure components such as the cover 200, the ejection mechanism 300, the charging module, the cleaning module, or other functional modules. Each end of the housing 100 has an independent earphone compartment 101, with the left and right earphones 400 placed within each compartment. Two covers 200 are respectively positioned at both ends of the housing 100 to seal or open the earphone compartments 101, enabling the storage and retrieval of the earphones 400. In this embodiment, two covers 200 are movably connected to both ends of the housing 100. The ejection mechanism 300 is driven by the two covers 200. The user can drive one cover 200 to move relative to the housing 100. Through the driving action of the ejection mechanism 300, the earphone 400 in the earphone compartment 101 at the other end is ejected from the corresponding earphone compartment 101. This achieves the function of ejecting the earphone 400 by driving the cover 200 at one end, making it easy for the user to take out the earphone 400. When it is necessary to take out another earphone 400, the above operation is repeated to drive the cover 200 at the other end of the earphone 400 to move.

[0056] It should be noted that in this embodiment, the two earphones 400 are respectively housed in two independent earphone compartments 101. Therefore, when one earphone 400 needs to be used independently, simply moving the cover 200 at the other end of the earphone 400 relative to the housing 100 will eject the earphone 400 from its corresponding earphone compartment 101. This operation is simple and does not open the earphone compartment 101 containing the unused earphone 400, thus reducing the risk of loss. Furthermore, having the two earphones 400 independently housed in two separate earphone compartments 101 reduces the size of the earphone compartments 101. The two earphone compartments 101 are located at opposite ends of the housing 100, resulting in a more compact structure and further miniaturizing the earphone case. Optionally, the inner cavity of the earphone compartment 101 can be configured as a contoured cavity of the earphone 400.

[0057] In practical applications, the movable connection method between the cover 200 and the box 100 can be determined according to the actual situation, such as a detachable movable connection method or a non-detachable movable connection method:

[0058] As an example, when the connection is detachable, the cover 200 can be removed from the housing 100. When the cover 200 is on the housing 100, it seals the corresponding earphone compartment 101. At this time, the cover 200 and the housing 100 can move relative to each other. When an earphone 400 needs to be taken out, the cover 200 corresponding to the earphone 400 can be removed from the housing 100. At this time, the corresponding earphone compartment 101 is opened, and then another cover 200 is driven to move relative to the housing 100. The ejection mechanism 300 ejects the earphone 400 from the opened earphone compartment 101 for the user to take out and use.

[0059] As an example, when the connection is non-separable, the cover 200 and the housing 100 are not detachable. When the cover 200 is placed on the housing 100, the cover 200 seals the corresponding earphone compartment 101. At this time, the cover 200 and the housing 100 can move relative to each other. When it is necessary to take out an earphone 400, the cover 200 corresponding to the earphone 400 can be moved (e.g., rotated or slid) relative to the housing 100 to open the corresponding earphone compartment 101. Then, another cover 200 is driven to move relative to the housing 100, and the earphone 400 to be taken out is pushed out from the opened earphone compartment 101 by the ejection mechanism 300 for the user to take out and use.

[0060] Based on the above connection method, the movement of the cover 200 relative to the box 100 under the action of external force can be sliding or rotating. The specific driving method is not limited here, as long as it can move relative to drive the ejection mechanism 300 to eject the earphone 400 at the other end.

[0061] In practical applications, the specific structure of the ejection mechanism 300 can be determined according to the actual situation. It can be a cam structure, lever structure, gear-rack mesh structure, or other structures, as long as it can eject the earphone 400 from the other end under the driving action of the cover 200. The ejection mechanism 300 and the housing 100 are movably connected; this can be a sliding connection or a rotating connection, etc., depending on the structure of the ejection mechanism 300, and is not limited here.

[0062] It should be noted that the cover 200 in this embodiment can both cover the earphone compartment 101 and drive the earphone 400 out, without the need for additional triggering or driving structures, which further simplifies the structure and reduces costs.

[0063] In the earphone case of this invention, each end of the case body 100 has an independent earphone compartment 101 for accommodating two earphones 400. Two covers 200 are movably connected to each end of the case body 100 to correspondingly close or open the two earphone compartments 101. An ejection mechanism 300 is provided on the case body 100, which is connected to the two covers 200. When it is necessary to remove the earphones 400, one cover 200 can be driven to move relative to the case body 100, causing the ejection mechanism 300 to eject the earphones 400 from the corresponding earphone compartment 101 at the other end. This facilitates user retrieval without opening the earphone compartment 101 containing the unused earphones 400, thus reducing the risk of losing the earphones 400.

[0064] In one embodiment of the present invention, please refer to Figures 1 to 4 as well as Figure 7 The two covers 200 are rotatably fitted onto the opposite ends of the box 100.

[0065] This embodiment illustrates the connection between the cover 200 and the housing 100. The cover 200 is rotatably fitted onto the end of the housing 100. It can be understood that when both covers 200 are on the end of the housing 100, the two covers 200 correspondingly seal the two earphone compartments 101. When it is necessary to remove the earphone 400, the first cover 200 can be removed from the housing 100 to open the corresponding earphone compartment 101. Then, the second cover 200 can be rotated to drive the ejection mechanism 300 relative to the housing 100, thereby ejecting the earphone 400 from the opened earphone compartment 101 for the user to retrieve. Furthermore, the first cover 200 can be placed back on the housing 100, the second cover 200 removed to open the other earphone compartment 101, and then the first cover 200 rotated to drive the ejection mechanism 300 relative to the housing 100, thereby ejecting the other earphone 400 from the corresponding earphone compartment 101 for the user to retrieve. In this way, the goal of removing both earphones 400 was achieved.

[0066] Understandably, the two earphone compartments 101 are located at opposite ends of the housing 100, and the two covers 200 are fitted onto the ends of the housing 100 to cover the two earphone compartments 101. For example, the housing 100 can be configured as a columnar structure, and the two covers 200 can be located at the axial ends of the housing 100 respectively. Then, when the covers 200 rotate, they can rotate around the axis of the housing 100 as the central axis.

[0067] In one embodiment of the present invention, please refer to Figures 2 to 6 Each earphone compartment 101 has an opening 102 at one end opposite to its corresponding cover 200. The ejection mechanism 300 includes a transmission component 310 and two protrusions 320. The transmission component 310 is movably connected to the earphone compartment 100 and is connected to the two covers 200. The two protrusions 320 are respectively located at opposite ends of the transmission component 310. The cover 200 at one end can rotate relative to the earphone compartment 100 to drive the transmission component 310 to move the protrusion 320 at the other end to the corresponding opening 102 to abut against the corresponding earphone 400.

[0068] This embodiment illustrates the structure of the ejection mechanism 300. The ejection mechanism 300 includes a transmission assembly 310 movably connected to the housing 100 and two protrusions 320 disposed at opposite ends of the transmission assembly 310. The transmission assembly 310 transmits power to the cover 200, and the protrusions 320 abut against the earphone 400. Specifically, the housing 100 has an opening 102 at the end of each earphone compartment 101 opposite to its corresponding cover 200. It can be understood that the opening 102 and the cover 200 are respectively disposed on opposite sides of the earphone compartment 101, and the opening 102 serves as a channel for the protrusions 320 to extend into the earphone compartment 101.

[0069] In practical applications, when it is necessary to remove the earphone 400, one end of the cover 200 can be rotated to drive the transmission component 310 to move relative to the housing 100. At this time, the two protrusions 320 also move accordingly until the other end of the protrusion 320 moves to the corresponding opening 102. The protrusion 320 will then push the corresponding earphone 400 out of the corresponding earphone compartment 101, thus realizing the function of ejecting the earphone 400. Furthermore, the above operation can be repeated by rotating the other end of the cover 200 to remove the other earphone 400.

[0070] Understandably, the transmission component 310 can be an integral or separate structure. The transmission component 310 mainly functions as a transmission device. When driven by the cover 200, it can move the protrusion 320 at the other end to the opening 102 to push out the earphone 400. The transmission component 310 and the housing 100 can be connected by sliding or rotating connections.

[0071] As an example, the protrusion 320 may be a convex hull or a convex block, etc.

[0072] In one embodiment of the present invention, please refer to Figures 2 to 6 The transmission assembly 310 includes two transmission members 311 and an elastic connector 312. The two transmission members 311 are movably connected to the housing 100 and located between the two earphone compartments 101. The two opposite ends of the two transmission members 311 are respectively connected to the two covers 200, and each transmission member 311 is provided with a protrusion 320. The elastic connector 312 is connected between the two transmission members 311.

[0073] This embodiment illustrates the structure of the transmission assembly 310. The transmission assembly 310 includes two transmission members 311 and an elastic connector 312. The two transmission members 311 are respectively provided for two earphone compartments 101. Each transmission member 311 is provided with a protrusion 320, that is, the protrusion 320 on each transmission member 311 corresponds to the earphone 400 being pushed out of the earphone compartment 101. The elastic connector 312 serves to connect the two transmission members 311, so that when the cover 200 at one end rotates and drives the transmission member 311 on the same side to move, it can drive the transmission member 311 at the other end to rotate together, thereby driving the protrusion 320 at the other end to move to the opening 102 at the other end and push out the earphone 400 at the other end, thus realizing the function of rotating the cover 200 at one end to push out the earphone 400 at the other end.

[0074] The elastic connector 312 connects the two transmission components 311. It not only allows the two transmission components 311 to move together under the driving action of the cover 200, but also provides elastic force for the two transmission components 311 to move in opposite directions. This allows the protrusion 320 to extend into the corresponding opening 102 when it moves to that opening, providing sufficient force to push the earphone 400 out of the earphone compartment 101. In practical application, when the protrusion 320 is not in the opening 102, it is pressed by the housing 100 or the cover 200. At this time, the elastic connector 312 is in a compressed state. When the protrusion 320 moves to the opening 102, the pressure on the protrusion 320 is released, and the elastic connector 312 recovers its deformation, driving the protrusion 320 to extend into the opening 102 to push against the corresponding earphone 400.

[0075] It should be noted that when both covers 200 are placed on the ends of the housing 100, the elastic connector 312 between the two transmission components 311 is in a compressed state. At this time, both transmission components 311 are held by the covers 200, so the two protrusions 320 are in a position that will not interfere with the corresponding earphone compartment 101. Therefore, no matter how the covers 200 are rotated, the two protrusions 320 will not extend into the opening 102 to abut against the corresponding earphone 400, thus preventing the earphone 400 from being pushed out. This achieves the function of preventing accidental touch when the two covers 200 are placed on the ends of the housing 100, further reducing the risk of losing the earphone 400.

[0076] Optionally, the resilient connector 312 is a spring.

[0077] In one embodiment of the present invention, please refer to Figures 2 to 6 The box body 100 is provided with two guide grooves 103 that are respectively connected to two openings 102. One end of the protrusion 320 of the two transmission members 311 is slidably engaged with the corresponding guide groove 103. The rotation of the cover 200 at any end can drive the two transmission members 311 to move along the corresponding guide groove 103, so as to drive the protrusion 320 at the other end to move closer to or away from the corresponding opening 102.

[0078] In this embodiment, a guide groove 103 communicating with the opening 102 is provided on the housing 100. One end of the protrusion 320 of the transmission member 311 slides in cooperation with the guide groove 103. Under the driving action of the cover 200, the transmission member 311 can drive the protrusion 320 to slide along the guide groove 103 to move closer to or away from the opening 102, thereby realizing the function of ejecting or storing the earphone 400. It can be understood that the guide groove 103 plays a guiding and limiting role for the transmission member 311, making the transmission movement of the transmission member 311 more stable and reliable, and preventing jamming during the operation of rotating and ejecting the earphone 400.

[0079] In practical applications, the shape and structure of the guide groove 103 can be determined according to the actual situation. For example, it can be an annular groove around the axis of the box 100, or it can be a straight groove, an arc groove, or a groove structure of other shapes. There is no limitation here.

[0080] As an example, considering the rotation method of the cover 200, the guide groove 103 can be set as an annular groove around the axis of the box 100. At this time, the rotation of the cover 200 can drive the transmission component 311 to rotate together in the guide groove 103, which simplifies the structural layout. The rotational motion is transmitted through the rotational motion without the need to design other transmission connection structures, which simplifies the transmission steps and further improves the smoothness of rotating and ejecting the earphone 400.

[0081] The transmission connection between the cover 200 and the transmission member 311 is exemplified by abutting connection, whereby the cover 200 drives the transmission member 311 to move using friction. Alternatively, in other embodiments, the cover 200 and the transmission member 311 can be connected by a snap-fit ​​connection or magnetic attraction, as long as rotating the cover 200 causes the transmission member 311 to rotate together.

[0082] As an example, please refer to Figures 2 to 6 The transmission component 311 includes an outer sleeve 3111, an inner sleeve 3112, and a connecting wall 3113. The outer sleeve 3111 is sleeved on the outside of the box body 100, and the end of the outer sleeve 3111 away from the elastic connector 312 abuts against the cover body 200. The inner sleeve 3112 is spaced inside the outer sleeve 3111 and is slidably fitted in the guide groove 103. The protrusion 320 is provided at the end of the inner sleeve 3112 away from the elastic connector 312. The connecting wall 3113 connects the ends of the inner sleeve 3112 and the outer sleeve 3111 near the elastic connector 312. The elastic connector 312 is connected between the connecting walls 3113 of the two transmission components 311.

[0083] This embodiment illustrates the structure of the transmission component 311. The outer sleeve 3111, inner sleeve 3112, and connecting wall 3113 form an annular groove structure for installation with the housing 100. The inner sleeve 3111 is positioned within the annular guide groove 103, and the outer sleeve 3111 is fitted over the outside of the housing 100, further ensuring the reliability of the connection between the transmission component 311 and the housing 100. The cover 200 is placed over the end of the housing 100, and its end is connected to the outer sleeve 3111. When the cover 200 is rotated, it causes the outer sleeve 3111 to rotate around the periphery of the housing 100. The inner sleeve 3112 then moves within the guide groove 103, thereby causing the protrusion 320 to move to the opening 102 and abut against the corresponding earphone 400. The elastic connector 312 connects the two connecting walls 3113, achieving the purpose of connecting the two transmission components 311.

[0084] In one embodiment of the present invention, please refer to Figures 1 to 7 The housing 100 has a cylindrical structure. The housing 100 includes a fixing part 110 located in the middle and mounting parts 120 located at both ends of the fixing part 110 along the axial direction. Two earphone compartments 101 are respectively formed in the two mounting parts 120. The ejection mechanism 300 is installed in the fixing part 110. Two covers 200 are detachably fitted on the outside of the two mounting parts 120. When the covers 200 are fitted on the mounting parts 120, the covers 200 can rotate relative to the mounting parts 120 and drive the ejection mechanism 300 to move.

[0085] This embodiment illustrates the structure of the housing 100. The housing 100 has a cylindrical structure and includes a fixing part 110 and mounting parts 120 located at both ends. Two earphone compartments 101 are formed in the two mounting parts 120 respectively, and two covers 200 are respectively fitted onto the two mounting parts 120. The earphone 400 at the other end can be pushed out by rotating one end of the cover 200, forming a lipstick-style structure with a novel appearance and improved user experience.

[0086] Understandably, based on the aforementioned embodiment where the rotating cover 200 pushes out the earphone 400, the inner cavity of the cover 200 can be set as a cylindrical cavity, and the outer wall of the mounting part 120 can be set as a cylindrical structure, so that the cover 200 can rotate smoothly around the outer periphery of the mounting part 120, further improving the smoothness of the rotation of the cover 200.

[0087] Furthermore, when the cover 200 is fitted onto the mounting part 120, the cover 200 and the mounting part 120 are interference-fitted, and the end of the cover 200 abuts against the end of the fixing part 110.

[0088] In this embodiment, when the cover 200 is fitted onto the mounting portion 120, the end of the cover 200 abuts against the end of the fixing portion 110, ensuring the sealing of the cover 200 and the housing 100 and preventing external dust and impurities from entering the earphone compartment 101. It is understood that the outer diameter of the mounting portion 120 is smaller than the outer diameter of the fixing portion 110. For example, the fixing portion 110 can be a shell 111 structure fitted onto the outside of the ejection mechanism 300. When the cover 200 is fitted onto the outside of the mounting portion 120, the outer surface of the cover 200 is flush with the outer surface of the fixing portion 110, achieving aesthetic integrity and further enhancing the appearance.

[0089] The cover 200 is detachably fitted onto the outside of the mounting part 120. Optionally, the cover 200 and the mounting part 120 are interference-fitted, allowing the cover 200 to be attached to or detached from the mounting part 120 by plugging and unplugging. As an example, the connection between the cover 200 and the mounting part 120 can refer to the connection structure of a conventional lipstick cap and base, and the two can be connected by magnetic attraction or interference fit, etc.

[0090] Furthermore, the end of the cover 200 is abutted against both ends of the ejector mechanism 300. It is understood that when the cover 200 is fitted onto the mounting portion 120, the cover 200 and the ejector mechanism 300 are connected in a transmission manner along their axial ends, and rotating the cover 200 can drive the ejector mechanism 300 to move together. As an example, the cover 200 and the ejector mechanism 300 are abutted against each other along their axial ends, and the cover 200 uses friction to drive the ejector mechanism 300 to move. Alternatively, in other embodiments, the cover 200 and the ejector mechanism 300 can also be connected by a snap-fit ​​connection or a magnetic connection, as long as rotating the cover 200 can drive the ejector mechanism 300 to rotate together.

[0091] In one embodiment of the present invention, please refer to Figures 2 to 5 The projections of the two earphone compartments 101 onto the longitudinal section of the housing 100 are centrally symmetrical.

[0092] In this embodiment, by arranging the projections of the two earphone compartments 101 on the longitudinal section of the housing 100 in a centrally symmetrical manner, space can be further saved, making the structural layout more compact and the earphone box smaller in size.

[0093] The present invention also proposes an earphone assembly, which includes earphones 400 and an earphone case. The specific structure of the earphone case is as described in the above embodiments. Since this earphone assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The earphone compartments 101 of the earphone case are used to house the earphones 400. Optionally, the earphones 400 are TWS earphones.

[0094] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
