[0001] This application claims priority to Chinese Patent Application No. 202323132851.5, filed on November 21, 2023, with the Chinese Patent Office, entitled “A Headphone Storage Device for a Mobile Terminal”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic product technology, and more particularly to an earphone storage device for mobile terminals. Background Technology

[0003] Currently, with the continuous development of science and technology and the economy, mobile terminal devices are increasingly appearing in people's work and life. These devices have greatly improved people's quality of life and are widely loved. In recent years, to meet user needs, the functions of mobile terminals have become increasingly diverse.

[0004] Watches are a commonly used mobile device. In the past, watches were only used to tell time, but now they can also connect to smartphones or wireless networks to receive external information, chat, and more. In recent years, a mobile device combining a watch and headphones has emerged. Headphones are generally small, inconvenient to carry, store, and charge. By combining a watch with headphones, the problems of headphone storage and charging are solved, while also enriching the watch's functionality and meeting users' personalized needs.

[0005] However, in the existing technology, headphones and watches are mainly connected and fixed by magnetic attraction, which is relatively complex, increases production and assembly costs, and the headphones are not very secure.

[0064] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0065] In one embodiment, a headphone storage device for a mobile terminal is described. It stores the headphone body 300 in the receiving cavity 100a of the terminal body 100, and the headphone body 300 is stored and retrieved by the elastic protrusion 220 on the inner sidewall 100b of the receiving cavity 100a engaging with the snap-fit ​​groove 311 on the headphone body 300. The overall structure of the spring 200 is not only simple, but also makes the connection between the headphone body 300 and the terminal body 100 reliable, which helps to prevent the headphone body 300 from falling off.

[0066] In some embodiments, see the accompanying drawings. Figures 1 to 4 A mobile terminal earphone storage device includes a terminal body 100 and an earphone body 300. The terminal body 100 has a receiving cavity 100a, and the inner sidewall 100b of the receiving cavity 100a has a protrusion 220 protruding from the inner sidewall 100b. The protrusion 220 is elastic, and the earphone body 300 is detachably disposed within the receiving cavity 100a. The earphone body 300 has a locking groove 311. When the earphone body 300 is housed within the receiving cavity 100a, the protrusion 220 engages with the locking groove 311 to restrict the position of the earphone body 300 within the receiving cavity 100a. When the earphone body 300 is removed from the receiving cavity 100a, the protrusion 220 disengages from the locking groove 311.

[0067] This application provides an elastic protrusion 220 in the receiving cavity 100a of the terminal body 100, so that when the earphone body 300 is placed in the receiving cavity 100a, the protrusion 220 can elastically deform and engage with the locking groove 311. In this way, the protrusion 220 restricts the position of the earphone body 300 within the receiving cavity 100a, which helps to prevent the earphone body 300 from falling out of the terminal body 100.

[0068] Optionally, the protrusion 220 may be a silicone protrusion, an elastic pin, or a protrusion or dot disposed on the spring sheet. To facilitate understanding of the solution of this application, the following description uses the example of the protrusion 220 being disposed on the spring sheet.

[0069] In some embodiments, a mobile terminal earphone storage device may include a terminal body 100, a spring 200, and an earphone body 300. At least one spring 200 is provided, and the terminal body 100 has a receiving cavity 100a that mates with the earphone body 300. Accordingly, the user can store the earphone body 300 within the receiving cavity 100a and remove it from the terminal body 100 when the earphone is needed. The spring 200 is disposed on the outer surface of the terminal body 100 and located on the inner wall 100b of the receiving cavity. The spring 200 is used to engage with the earphone body 300 to securely connect and fix the earphone body 300 within the receiving cavity 100a.

[0070] The spring clip 200 includes a base plate 210 and a protrusion 220. The protrusion 220 is disposed on the base plate 210 and close to the terminal body 100. Correspondingly, the inner wall 100b of the receiving cavity 100a is provided with a through hole 100c that mates with the protrusion 220. The earphone body 300 is provided with a snap-fit ​​groove 311 that matches the protrusion 220. The protrusion 220 passes through the through hole 100c, such that the side of the protrusion 220 away from the base plate 210 is located within the receiving cavity 100a. Accordingly, when the earphone body 300 is housed within the receiving cavity 100a, the protrusion 220 and the snap-fit ​​groove 311 of the earphone body 300 engage with each other to fix the earphone body 300 within the receiving cavity 100a.

[0071] Alternatively, the protrusion 220 may also be a separately provided elastic ejector pin or an elastic tab integrally provided with the inner sidewall 100b of the receiving cavity 100a, etc., which are not specifically limited here.

[0072] Optionally, the inner wall 100b of the accommodating cavity 100a may be provided with a separately elastic protrusion 220. For example, when the earphone body 300 is placed into the accommodating cavity 100a, the protrusion 220 undergoes elastic deformation and engages with the locking groove 311, achieving a locking engagement with the locking groove 311. This helps to limit the position of the earphone body 300 within the accommodating cavity 100a, preventing the earphone body 300 from falling out.

[0073] Optionally, the inner wall 100b of the accommodating cavity 100a may also be provided with an elastic element, and the protrusion 220 is disposed on the elastic element. The elastic element may be, but is not limited to, a spring or a sheet. This allows the protrusion 220 to engage with the snap-fit ​​groove, thus limiting the position of the earphone body 300 within the accommodating cavity 100a.

[0074] It should be noted that the protrusion 220 is located on the inner sidewall of the receiving cavity 100a, while the substrate 210 and other structures of the spring piece 200 are located on the outer surface of the sidewall of the receiving cavity 100a. In other words, the protrusion 220 needs to be located inside the receiving cavity 100a to effectively engage with the locking groove 311, and the substrate 210 and other structures are located on the outer side of the receiving cavity 100a to avoid affecting the placement of the earphone body 300.

[0075] In this embodiment, the earphone body 300 and the terminal body 100 can be connected and fixed by the spring contact 200, thereby housing the earphone body 300 within the receiving cavity 100a of the terminal body 100. Compared to the prior art where the earphone body 300 and the terminal body 100 are connected by magnetic attraction, the spring contact 200 in this embodiment has a simple structure, avoids the adverse effects of magnetism on the earphone and mobile terminal, and provides a good connection effect, making it less likely for the earphone body 300 to fall off, protecting the user's property safety, and facilitating production, assembly, and maintenance.

[0076] Understandably, when the earphone body 300 is not needed, the user places it in the receiving cavity. Due to the good elasticity of the spring 200, after the earphone body 300 contacts the protrusion 220, it pushes the spring 200 to move away from the terminal body 100. Once the earphone body 300 is in place, the spring 200 is no longer compressed by the earphone body 300. Under the action of the restoring force, the spring 200 moves towards the terminal body 100, causing the protrusion 220 to engage with the locking groove 311, thereby placing the earphone body 300 in the receiving cavity. Correspondingly, when the user needs to wear the earphone, the user removes the earphone body 300 from the receiving cavity and puts it on their ear. The spring 200's good elasticity makes it easy for the user to remove the earphone body 300.

[0077] Preferably, the sidewalls of the protrusions 220 are connected by a smooth arc surface, and the sidewalls of the locking groove 311 are also connected by a smooth arc surface. This makes the protrusions 220 and the locking groove 311 have relatively smooth walls, which is conducive to their engagement and disengagement, and facilitates the storage and retrieval of the earphone body 300.

[0078] In one embodiment, see the accompanying drawings. Figure 5 This embodiment further describes the earphone body 300. Specifically, the earphone body 300 includes an earbud head 310 and a first earphone arm 320. The earbud head 310 is disposed at one end of the first earphone arm 320 and is used to emit sound. Correspondingly, a snap-fit ​​groove 311 is disposed on the earbud head 310, and a spring piece 200 is adapted to snap-fit ​​with the earbud head 310.

[0079] Furthermore, the earphone body 300 also includes a second earphone arm 330, which is located on the side of the first earphone arm 320 away from the earbud head 310. The first earphone arm 320 and the second earphone arm 330 are capable of relative rotation to adjust the opening angle between them. It is understood that the earphone body 300 has an unfolded mode and a folded mode. When the earphone body 300 is in the unfolded mode, the first earphone arm 320 and the second earphone arm 330 are aligned, allowing the earphone body 300 to be stored within the receiving cavity. Correspondingly, when the earphone body 300 is in the folded mode, there is an opening angle between the first earphone arm 320 and the second earphone arm 330, facilitating the user to wear the earphone body 300 on their ears.

[0080] In one embodiment, this embodiment further describes 100 sets of terminal bodies. Specifically, refer to the accompanying drawings. Figures 3 to 7 The terminal body 100 includes mounting members 110 and a middle frame 120. Two mounting members 110 are provided. A mounting hole 121 for cooperating with the earbud head 310 is provided on one side wall of the middle frame 120. A through hole is provided on the side wall of the mounting hole 121, and the base plate 210 of the spring piece 200 is tightly attached to the outer surface of the mounting hole 121. Correspondingly, the two mounting members 110 are respectively provided on two opposite side walls of the middle frame 120, located on both sides of the mounting hole 121. It can be understood that when the earphone body 300 is housed in the receiving cavity 100a, the earbud head 310 is housed in the mounting hole 121, and the first earphone arm 320 is connected to the side wall of the middle frame 120.

[0081] In some embodiments, a charging PIN pin 122 is also provided on the mid-frame 120, and correspondingly, a charging interface that mates with the charging PIN pin 122 is also provided on the first earphone arm 320. When the earphone body 300 is stored inside the terminal body 100, the first earphone arm 320 contacts the side wall of the mid-frame 120, causing the charging interface to connect with the charging PIN pin 122. It is understood that when the user does not need to use the earphone body 300, storing it inside the terminal body 100 allows the terminal body 100 to charge the earphone body 300, improving the user experience.

[0082] Furthermore, a receiving space 120a is provided between the mounting member 110 and the side wall of the middle frame 120, the earbud head 310 is housed in the mounting hole 121, and the first earphone arm 320 and the second earphone arm 330 are housed in the receiving space 120a. Accordingly, the mounting hole 121 and the receiving space 120a are interconnected to form a receiving cavity 100a.

[0083] When in use, when the earphone body 300 needs to be stored in the accommodating cavity 100a, the second earphone arm 330 and the first earphone arm 320 are sequentially arranged in the accommodating space 120a, and then the earbud head 310 is arranged in the mounting hole 121. The earbud head 310 and the protrusion 220 on the spring piece 200 are engaged with each other to store the earphone body 300 in the accommodating cavity 100a.

[0084] Furthermore, a limiting post 121a is provided on the outer surface of the sidewall of the mounting hole 121. Correspondingly, a limiting hole 210a is provided on the substrate 210 to cooperate with the limiting post 121a. The limiting post 121a is provided through the limiting hole 210a to fix the spring piece 200 on the sidewall of the mounting hole 121. Accordingly, the limiting hole 210a and the protrusion 220 are sequentially provided on the substrate 210 along the length direction of the substrate 210. When the spring piece 200 is pushed by the headphone body 300, the limiting post 121a plays a connecting and fixing role, causing the spring piece 200 to move relative to the limiting post 121a. Finally, under the action of the restoring force of the spring piece 200, the protrusion 220 and the locking groove 311 engage with each other.

[0085] In one embodiment, the spring piece 200 is further described. Specifically, at least one spring piece 200 is provided, and the number of spring pieces 200 corresponds to the number of earphone bodies 300. When there is one earphone body 300, there is one spring piece 200, which houses and fixes the earphone body 300 in the receiving cavity. Of course, when there are two earphone bodies 300, there are two spring pieces 200, and correspondingly, there are also two mounting holes 121. The two mounting holes 121 are not in contact, and each mounting hole 121 is provided with a spring piece 200, which fixes the corresponding earphone body 300 in the receiving cavity.

[0086] Accordingly, the two mounting holes 121 can intersect and be interconnected, and in this case, there are two spring contacts 200, as shown in the attached diagram of the instruction manual. Figure 6 Two spring pieces 200 are connected to each other by a connector 230, which is located at the junction of the two mounting holes 121. The mounting holes 121 are nearly circular, and the spring pieces 200 are positioned close to the outer surface of the mounting holes 121, resulting in a bent spring piece configuration. When the two mounting holes 121 intersect, the junction of the two mounting holes 121 has a certain degree of concavity. The connector 230 is located at the junction of the two mounting holes 121, positioned above the spring piece 200. The connector 230 is located near the protrusion 220, that is, the protrusion 220 is located at the end of the substrate 210 near the connector 230. The limiting hole 210a is located at the end of the substrate away from the connector. When the protrusion 220 is pressed by the earpiece head 310, the protrusion 220 moves away from the middle frame 120, and the connector 230 can further increase the elasticity of the spring piece 200, thereby improving the connection strength.

[0087] Optionally, the shape of the substrate 210 can be adapted to the shape of the outer surface of the mounting hole 121; that is, the substrate 210 can be an arc-shaped plate. Further, the connector 230 can be flat, connecting two arc-shaped substrates 210 whose surfaces are concave relative to the connector, so that the three connected together form a shape similar to an inverted "m". This facilitates the connector 230's engagement with the concave position at the connection point of the two mounting holes 121, improving the stability of the two spring clips 200.

[0088] Of course, there can be three or more spring clips 200, and two adjacent spring clips 200 can be connected by connectors 230. In this way, multiple spring clips 200 can be provided on the outer surface of the mounting hole 121.

[0089] In one embodiment, see the accompanying drawings. Figures 7 to 10The earphone storage device for mobile terminals provided in this embodiment also includes a limiting plate 400, which is disposed on the side of the mounting member 110 near the middle frame 120 or on the side of the middle frame 120 near the mounting member 110.

[0090] The limiting plate 400 is provided with a limiting protrusion 421, and the first earphone arm 320 is provided with a limiting groove 321. The limiting groove 321 is adapted to cooperate with the limiting protrusion 421 to fix the first earphone arm 320 in the accommodating space.

[0091] Optionally, the limiting plate 400 may be made of elastic plastic materials such as TPE, PVE, and PP, but this application does not make specific limitations here.

[0092] Furthermore, the limiting plate 400 includes a first part 410 and a second part 420. An inner groove 111 is provided on the middle frame 120 or the mounting component 110. The limiting plate 400 is disposed within the inner groove 111, and the first part 410 is connected and fixed to the bottom of the inner groove 111. The second part 420 is disposed at one end of the first part 410, and a gap is provided between the second part 420 and the bottom of the inner groove 111, allowing the second part 420 to deform relative to the first part 410 when subjected to external forces.

[0093] The side of the first part 410 near the first earphone arm 320 is connected to the side of the second part 420 near the first earphone arm 320 by a smooth plane. The limiting protrusion 421 is provided on the second part 420, and the thickness of the first part 410 is the same as the depth of the inner groove 111.

[0094] For ease of explanation, the inner groove 111 is positioned on the side of the mounting member 110 near the middle frame 120. Correspondingly, the limiting plate 400 is positioned within the inner groove 111, between the middle frame 120 and the mounting member 110. The first portion 410 has a first mounting part, and the bottom of the inner groove 111, corresponding to the first portion 410, has a second mounting part. The first mounting part is detachably connected to the second mounting part. One of the first and second mounting parts can be a connecting post 111a, and the other can be a connecting hole 410a. In one example, the bottom of the inner groove 111 has a connecting post 111a, and the first portion 410 has a connecting hole 410a that mates with the connecting post 111a. In another example, the bottom of the inner groove 111 has a connecting hole 410a, and the first portion 410 has a connecting post 111a that mates with the connecting hole 410a. The connecting post 111a passes through the connecting hole 410a to achieve hole-post connection, so as to install the limiting plate 400 in the inner groove 111, thereby achieving effective fixation of the limiting plate 400 in the inner groove 111.

[0095] Optionally, the connection between the first mounting part and the second mounting part can also be a snap-fit ​​connection, a pin connection, an adhesive connection, etc., which are not specifically limited here.

[0096] Optionally, the first part 410 can be integrally formed with the inner groove 111. This helps to reduce the installation steps during product manufacturing.

[0097] It is understandable that the inner groove 111 can also be provided in the second earphone arm 330, so that the earphone body 300 can be limited in the accommodating space 120a through the second earphone arm 330. The specific implementation method is the same as that of the first earphone arm 320, and will not be described in detail here.

[0098] Considering that the second part 420 will deform and recover, to improve the deformation effect and recovery ability of the second part 420, optionally, a slot 430 is provided at the connection between the first part 410 and the second part 420 facing the inner groove 111, and the bottom of the slot 430 can be arc-shaped. This application reduces the thickness at the connection between the first part 410 and the second part 420, so that the second part 420 can deform better relative to the first part 410. In addition, the arc-shaped bottom of the slot 430 helps to effectively support the slot 430 and prevent the second part 420 from deforming excessively and being unable to recover its deformation.

[0099] Understandably, when the earphone body 300 is housed within the accommodating cavity 100a, the second earphone arm 330 is initially positioned within the accommodating space 120a. As the first earphone arm 320 moves, it presses against the limiting protrusion 421, causing the second part 420 to move away from the mid-frame 120 until the limiting protrusion 421 and the limiting groove 321 engage with each other, thus connecting and fixing the first earphone arm 320 within the accommodating space 120a. In this way, the interaction between the spring piece 200 and the limiting plate 400 further enhances the connection strength between the earphone body 300 and the mid-frame 120.

[0100] In one embodiment, see the accompanying drawings. Figure 7 The earphone storage device for this mobile terminal also includes a base plate 500 and a base frame 600. The middle frame 120 includes a middle frame body 120b and an extension 120c disposed on the upper end surface of the middle frame body 120b. The extension 120c is disposed circumferentially along the middle frame body 120b. The base plate 500 is disposed at the opening on the lower end surface of the middle frame body 120b. The base frame 600 is sleeved on the outside of the base plate 500 and contacts the lower end surface of the middle frame body 120b. A limiting groove 600a is provided on the side of the base frame 600 near the middle frame 120. The spring piece 200 is located in the limiting groove 600a, and the spring piece 200 does not contact the bottom of the limiting groove 600a, so that the spring piece can move relative to the base frame 600 within the limiting groove 600a.

[0101] The upper end face of the mounting part 110 is connected to the extension 120c, and the lower end face of the mounting part 110 is connected to the bottom frame 600 to form an accommodating space 120a.

[0102] Understandably, when the mobile terminal is set as a watch, the mounting piece 110 is equipped with a watch strap, and the upper surface of the middle frame is also equipped with a display screen for displaying information. Correspondingly, the watch is also equipped with a camera module, which is located at the end of the middle frame 120 away from the mounting hole 121.

[0103] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
