Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a Bluetooth headphone. Background Technology

[0002] Currently, there are various types of Bluetooth headphones, such as semi-in-ear headphones or earbuds. However, when wearing these Bluetooth headphones, the relatively low friction between the headphones and the ear can cause them to fall out, especially during exercise. Therefore, a new type of headphone has emerged on the market.

[0003] This new type of earphone includes a main body (such as...) Figure 12 (as shown in P) and ear wings (as shown in P) Figure 12 As shown in L), the main body includes snap-fit ​​terminals arranged opposite to each other (such as...). Figure 12 As shown in Figure I, the ear wing is movably positioned at the mounting end. By engaging with the ear wing at the snap-fit ​​end, the earphone is snapped onto the user's ear, thus enhancing the friction between the Bluetooth earphone and the ear and effectively preventing the earphone from falling out.

[0004] However, in the above structure, if the user has small ears, the procedure for wearing the ear flap is as follows: first, the ear flap must be placed against the ear, and then the relative position of the clip end on the ear must be gradually adjusted until the clip is in place. The entire wearing process is slow, and during the adjustment to the appropriate position, the ear flap is constantly elastically pressed against the ear, and the frequent friction between the two can easily cause discomfort to the user.

The connecting structure cooperates with the locking portion to lock the ear wing in the insertion portion.

[0010] The locking member is movably connected to the outer shell so that when the operating part is touched, the locking part can move and unlock the connecting structure, at which time the first elastic member can drive the ear wing to pop out of the insertion part.

[0011] In one embodiment, the ear wing includes a sidewall disposed in a second direction, and the connecting structure is a slot disposed on the sidewall;

[0012] The locking member is slidably connected to the outer shell in the second direction, which is perpendicular to the first direction; the locking part is a locking post, and when the ear wing is locked, the locking groove is located in the first direction of the locking post so as to engage with the locking post.

[0013] In one embodiment, the sidewall includes a guide surface adjacent to the side of the slot near the snap-fit ​​end, and the guide surface is set at an angle to the first direction;

[0014] The locking assembly further includes a second elastic element connected to the locking member. When the ear flap retracts, the guide surface moves relative to the locking post. The second elastic element can drive the locking post to abut against the guide surface and cooperate with the guide surface to move the locking post into the locking slot.

[0015] In one embodiment, the housing is provided with a mounting base, the mounting base having a first sliding groove and a second sliding groove, the second sliding groove being spaced apart from the first sliding groove on the third direction side; the ear wing is slidably connected to the first sliding groove, the locking member is slidably connected to the second sliding groove, the bottom of the second sliding groove has a guide groove, the guide groove is connected to the first sliding groove, and the locking post passes through the guide groove so that when the ear wing moves to the point where the locking groove is opposite to the guide groove, the locking post can engage with the locking groove, the third direction being perpendicular to the first direction and the second direction respectively.

[0016] In one embodiment, the second groove includes a sliding portion and a connecting portion, the connecting portion being located on one side of the sliding portion in the first direction;

[0017] The locking component further includes a sliding seat, the locking pin is disposed on the sliding seat, the sliding seat is slidably connected to the sliding part, the sliding seat is provided with a protrusion, the protrusion is located in the connecting part, the connecting part includes a limiting wall disposed in the second direction toward the protrusion, and the second elastic member is sandwiched between the limiting wall and the protrusion.

[0018] In one embodiment, a first limiting post is provided on the limiting wall, and the second elastic member is fitted onto the first limiting post; and / or, a second limiting post is provided on the groove wall of the first sliding groove, and the first elastic member is fitted onto the second limiting post.

[0019] In one embodiment, the outer casing includes an inner shell and an outer shell, the mounting base is disposed on the inner shell, the operating part is a lever connected to the sliding seat, the outer shell has an opening, the outer shell covers the inner shell, and the lever passes through the opening.

[0021] In one embodiment, the end of the ear wing facing away from the snap-fit ​​end is covered with an adhesive-coated component.

[0022] In one embodiment, the snap-fit ​​end is a protrusion disposed on the outer peripheral surface, and the protrusion has a gradually narrowing trend in the direction away from the insertion portion.

[0023] Compared with the prior art, the Bluetooth headset provided by this utility model has the following advantages: the Bluetooth headset has strong compatibility and adaptability, which can greatly improve the comfort of users during the wearing process.

[0024] Specifically, the Bluetooth headset is equipped with a locking component. The locking member of the locking component can lock the ear wing using the connecting structure of the locking ear wing, so that the ear wing is locked in the insertion part. When the user's ears are small, the ear wing can be locked in the insertion part before wearing. Since there is no ear wing to affect the ear, it is easy to adjust the relative position of the clip end in the ear. After the adjustment is completed, since the operating part is exposed on the outer peripheral surface facing away from the user's ear, the user can operate the operating part to move the locking member relative to the shell, the connecting structure separates from the locking part, and the locking member unlocks the ear wing. At this time, the ear wing pops out under the action of the first elastic member and abuts against the ear, thereby completing the Bluetooth headset being clipped into the ear. Compared with the existing embodiment where the ear wing needs to rub against the ear frequently, during the entire wearing process, the ear wing does not come into contact with the ear when the user adjusts the position of the Bluetooth headset, which is more effortless. After the adjustment is completed, the ear wing is directly unlocked to complete the Bluetooth headset clipping. The ear wing does not rub against the ear, making the user's wearing process more comfortable. Attached Figure Description

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0046] This utility model embodiment provides a Bluetooth headset 1000, such as Figure 1 - Figure 7 As shown, the Bluetooth headset 1000 includes a housing 10, a locking component 20, and a fixing component 30. The housing 10 includes an insertion portion 11 for insertion into a user's ear, the insertion portion 11 including an outer peripheral surface 111 covered by the ear, and the outer peripheral surface 111 including a snap-fit ​​end 1111. The locking component 20 includes a locking member 21, the locking member 21 including a locking portion 211 installed inside the housing 10, and an operating portion 213 connected to the locking portion 211, the operating portion 213 being exposed on the side of the outer peripheral surface facing away from the user's ear. The fixing component 30 includes an ear wing 31 and a first elastic member 32, the ear wing 31 being movably disposed at the insertion portion 11, and the ear wing 31 and the snap-fit ​​end 1111 being in a first direction (e.g., Figure 3The earpieces (as shown in the X direction) are spaced apart and arranged opposite to each other. A first elastic member 32 is connected to the ear wing 31, and a connecting structure 311 is provided at the ear wing 31. The connecting structure 311 cooperates with the locking part 211 to lock the ear wing 31 in the insertion part 11. The locking member 21 is movably connected to the outer shell 10 so that when the operating part 213 is touched, the locking part 211 can move and unlock with the connecting structure 311. At this time, the first elastic member 32 can drive the ear wing 31 to pop out of the insertion part 11. This application can solve the problem of poor wearability of the novel Bluetooth headset 1000 in the prior art, which leads to user discomfort. The Bluetooth headset 1000 has strong compatibility and can greatly improve the comfort of the user during wearing.

[0047] Specifically, the Bluetooth headset 1000 is equipped with a locking component 20. The locking member 21 of the locking component 20 can lock the ear wing 31 using the connecting structure 311 of the locking ear wing 31, so that the ear wing 31 is locked in the insertion part 11. When the user's ears are small, the ear wing 31 can be locked in the insertion part 11 before wearing. Since there is no ear wing 31, the relative position of the latch end 1111 in the ear can be easily adjusted. After adjustment, since the operating part 213 is exposed on the side of the outer peripheral surface 111 facing away from the user's ear, the user can operate the operating part 213 to make the locking member 21 relative to the outer shell. 10. The connecting structure 311 separates from the locking part 211, and the locking member 21 unlocks from the ear wing 31. At this time, the ear wing 31 pops out under the action of the first elastic member 32 and abuts against the ear, thus completing the Bluetooth headset 1000 being inserted into the ear. Compared with the prior art embodiment where the ear wing 31 needs to rub against the ear frequently, during the entire wearing process, the ear wing 31 does not contact the ear when the user adjusts the position of the Bluetooth headset 1000, which is less effort. After adjustment, the ear wing 31 is unlocked directly to complete the insertion of the Bluetooth headset 1000. The ear wing 31 does not rub against the ear, making the user's wearing process more comfortable. Furthermore, since the locking member 21 is partially exposed outside the shell 10, the user can unlock the ear wing 31 by operating the locking member 21, which is more operable and allows the user to more clearly see whether the ear wing 31 is accurately locked, resulting in a better user experience.

[0048] In addition, the locking component 20 can also facilitate the storage of the Bluetooth headset 1000, reduce the space occupied by the Bluetooth headset 1000, and make it easy to place it in the earphone case, which also helps to reduce the size of the earphone case and improve the portability of the product.

[0049] It is worth mentioning that the Bluetooth headset 1000 of this application offers better wearing stability and is less prone to falling out. Because the ear wing 31 protrudes from the outer surface of the insertion portion 11 and engages with the latching end 1111 to secure the Bluetooth headset 1000 to the user's ear, the friction between the Bluetooth headset 1000 and the ear is enhanced, effectively preventing the Bluetooth headset 1000 from falling out. Furthermore, the ear wing 31 and the latching end 1111 are positioned opposite each other in the first direction of the insertion portion 11. After the Bluetooth headset 1000 is secured, the latching end 1111 and the ear wing 31 provide support on both sides of the insertion portion 11, resulting in a more balanced force on the Bluetooth headset 1000 within the ear, thus ensuring a more secure fit. In addition, the ear wing 31 of the Bluetooth headset 1000 is movably disposed within the insertion portion 11. When wearing the Bluetooth headset 1000, the ear wing 31 can be adapted and fixed according to the size of the ear, improving the flexibility and adaptability of the Bluetooth headset 1000.

[0050] In this application, the first elastic element 32 can be a spring, a spring pad, or other device that can provide elastic driving force (such as a hydraulic elastic damper), and there is no limitation on it here.

[0051] There are many ways to configure the connecting structure 311 and the locking element 21; several embodiments are described below. (Refer to...) Figure 6 and Figure 7 In one embodiment, the ear wing 31 includes a second direction (e.g., Figure 3 The sidewall 3111 (shown in the Y direction) is provided on the sidewall 3111, and the connecting structure 311 is a slot 3111a provided on the sidewall 3111. The locking member 21 is slidably connected to the outer shell 10 in a second direction, which is perpendicular to the first direction. The locking part 211 is a locking post 2111. When the ear wing 31 is locked, the slot 3111a is located in the first direction of the locking post 2111 to engage with the slot 3111a. In another embodiment, the connecting structure 311 is a first hook (not shown in the figure) provided on the sidewall 3111, and the locking part 211 is a second hook (not shown in the figure). When the ear wing 31 is locked, the first hook and the second hook are engaged. In another embodiment, the connecting structure 311 is a first magnetic attractor (not shown in the figure) disposed on the side wall 3111, and the locking part 211 is a second magnetic attractor (not shown in the figure). When the ear wing 31 is locked, the first magnetic attractor is magnetically connected to the second magnetic attractor. Specifically, both the first magnetic attractor and the second magnetic attractor are magnets.

[0052] Reference Figure 7In one embodiment, the sidewall 3111 includes a guide surface 3111b, which is adjacent to the side of the slot 3111a near the latching end 1111. The guide surface 3111b is set at an angle to the first direction. The locking assembly 20 also includes a second elastic member 22, which is connected to the locking member 21. When the ear wing 31 retracts, the guide surface 3111b moves relative to the latch 2111. The second elastic member 22 can drive the latch 2111 to abut against the guide surface 3111b and cooperate with the guide surface 3111b to move the latch 2111 into the slot 3111a. With this configuration, the retraction of the ear wing 31 allows the latch 2111 to fall into the slot 3111a, achieving automatic locking of the ear wing 31. The locking operation is more convenient and faster, and the locking process is more efficient.

[0053] Specifically, the second elastic element 22 is a spring. The second elastic element 22 causes the locking element 21 to have a tendency to move towards the side wall 3111 of the ear wing 31 in the second direction. When locking is required, a force is applied to the ear wing 31 to retract it into the insertion part 11. During the retraction process, the locking post 2111 will first contact the guide surface 3111b, and under the action of the second elastic element 22, the locking post 2111 and the guide surface 3111b can maintain a tight fit, and the guide surface 3111b can also drive... The locking post 2111 moves relative to the second elastic member 22 in the second direction, overcoming the elastic force of the second elastic member 22. At this time, the second elastic member 22 is compressed and stores energy. When the ear wing 31 is fully retracted to the insertion part 11, the locking post 2111 moves to the corresponding position in the locking groove 3111a under the guidance of the guide surface 3111b. At this time, since the locking post 2111 is disengaged from the guide surface 3111b, the second elastic member 22 can release energy and drive the locking post 2111 into the locking groove 3111a, thereby locking the ear wing 31. Locking can be achieved in just one step. The locking operation is convenient, and the entire locking process is smooth and stable, effectively preventing jamming.

[0054] Reference Figure 4 , Figure 8 as well as Figure 9 In one embodiment, a mounting base 12 is provided inside the housing 10, and the mounting base 12 is provided in a first sliding groove 121 and a second sliding groove 122; the second sliding groove 122 is located in a third direction of the first sliding groove 121 (e.g., Figure 5On one side of the Z-direction (as shown in the diagram), the ear wing 31 is slidably connected to the first slide groove 121, and the locking member 21 is slidably connected to the second slide groove 122. The bottom of the second slide groove 122 is provided with a guide groove 1221, which is connected to the first slide groove 121. The locking pin 2111 passes through the guide groove 1221 so that when the ear wing 31 moves to the position of the locking groove 3111a opposite to the guide groove 1221, the locking pin 2111 can engage with the locking groove 3111a. The third direction is perpendicular to the first direction and the second direction, respectively. With this configuration, both the ear wing 31 and the locking member 21 are installed at the mounting base 12. The mounting base 12 serves as the same mounting reference for the ear wing 31 and the locking member 21, which can improve the positional accuracy of the locking pin 2111 when it engages with the locking groove 3111a, thereby improving the stability and reliability of locking and unlocking.

[0055] Specifically, the first slide groove 121 provides guidance for the ear wing 31, so that the ear wing 31 always moves relative to the outer shell 10 in the first direction. The second slide groove 122 provides guidance for the locking member 21, so that the locking member 21 always moves relative to the outer shell 10 in the second direction. The locking post 2111 passes through the guide groove 1221. The guide groove 1221 can limit the locking post 2111, so that the locking post 2111 can move along the preset path without deviation. Thus, when the locking groove 3111a of the ear wing 31 moves to be aligned with the guide groove 1221, the locking post 2111 is accurately placed into the locking groove 3111a.

[0056] Reference Figure 9 and Figure 10 In one embodiment, the second slide groove 122 includes a sliding portion 1222 and a connecting portion 1223, with the connecting portion 1223 located on one side of the sliding portion 1222 in a first direction. The locking member 21 also includes a sliding seat 212, with a locking pin 2111 disposed on the sliding seat 212. The sliding seat 212 is slidably connected to the sliding portion 1222. The sliding seat 212 has a protrusion 2121 located in the connecting portion 1223. The connecting portion 1223 includes a limiting wall 1223a disposed in the second direction facing the protrusion 2121. The second elastic member 22 is sandwiched between the limiting wall 1223a and the protrusion 2121. With this configuration, the second elastic member 22 sandwiched between the limiting wall 1223a and the protrusion 2121 improves the stability of the connection while ensuring that the elastic force applied by the second elastic member 22 is fully applied to the locking member 21, allowing the locking member 21 to be stably reset.

[0057] Reference Figure 4 and Figure 11In one embodiment, a first limiting post 1223b is provided on the limiting wall 1223a, and a second elastic member 22 is fitted onto the first limiting post 1223b; and / or, a second limiting post 1211 is provided on the groove wall of the first sliding groove 121, and a first elastic member 32 is fitted onto the second limiting post 1211. Thus, the first limiting post 1223b can limit the installation of the second elastic member 22, and the second limiting post 1211 can limit the installation of the first elastic member 32, so that the first elastic member 32 and the second elastic member 22 will not bend under force, ensuring that the first elastic member 32 and the second elastic member 22 can fully compress, store, and release energy, thereby improving the overall reliability of the product structure.

[0058] Reference Figure 8 In one embodiment, the outer casing 10 includes an inner casing 13 and an outer casing 14. A mounting base 12 is disposed on the inner casing 13. The operating part 213 is a lever 2131213 connected to a sliding base 212. The outer casing 14 has an opening 141 covering the inner casing 13, and the lever 2131213 passes through the opening 141. Thus, the lever 2131213 facilitates user operation of the locking member 21, while the opening 141 limits the maximum range of movement of the lever 2131213. Even when the user applies excessive force, the locking member 21 remains on its predetermined trajectory, improving operational safety.

[0059] It is worth mentioning that implementing the above embodiments can greatly improve assembly efficiency and reduce assembly difficulty; to better understand the effects of this technology, the following detailed explanations will provide further details on specific operational methods.

[0060] Mounting base 12 is disposed on inner shell 13. When installing fixing component 30, the assembler can directly install ear wing 31 and first elastic member 32 into first slide groove 121. When installing locking component 20, the assembler can first place second elastic member 22 into connecting part 1223, and make one end of second elastic member 22 connect with limiting wall 1223a of connecting part 1223. Then, align the locking post 2111 of locking member 21 with guide groove 1221, so that sliding base 212 is placed. After the locking member 21 is installed at the sliding part 1222, the second elastic member 22 is positioned between the protrusion 2121 and the limiting wall 1223a. Finally, the outer shell 14 is fastened. Since the lever 2131213 is restricted by the opening 141 of the outer shell 14, the locking member 21 can automatically adjust to abut the other end of the protrusion 2121 against the other end of the second elastic member 22. At this time, the second elastic member 22 is sandwiched between the protrusion 2121 and the limiting wall 1223a. The entire installation process of the locking assembly 20 does not require pressing the second elastic member 22. Simply place each component in its corresponding position and fasten the inner shell 13 and the outer shell 14 together to position the second elastic member 22 as needed. Since the installation process does not require manually pressing the second elastic member 22 to adjust the position of the locking member 21, the assembly process is not affected by the second elastic member 22, making assembly simpler and installation more efficient.

[0061] Reference Figure 8 In one embodiment, the Bluetooth headset 1000 further includes a control circuit board 40. A insertion boss 123 is provided on the side of the mounting base 12 near the snap-fit ​​end 1111, and the control circuit board 40 is mounted on the insertion boss 123. This configuration also allows the mounting base 12 to limit and fix the control circuit board 40, improving the reliability of the control circuit board 40 connection while facilitating assembly by personnel.

[0062] Specifically, the insertion boss 123 is provided with a plug post 1231, and the control circuit board 40 is provided with a socket 41, with the plug post 1231 inserted into the socket 41.

[0063] Reference Figure 4 In one embodiment, the end of the ear wing 31 facing away from the snap-fit ​​end 1111 is covered with a rubber-coated part 312. Thus, the rubber-coated part 312 improves wearing comfort. Specifically, the rubber-coated part 312 can be silicone or a soft pad, or of course, other soft gels; no limitation is made here.

[0064] Preferably, the side of the overmolded part 312 facing away from the snap-fit ​​end 1111 has an arc-shaped surface, which can better fit the outer contour of the ear, improving wearing stability and comfort.

[0065] In one embodiment, the snap-fit ​​end 1111 is a protrusion provided on the outer peripheral surface 111, and the protrusion has a gradually narrowing tendency in the direction away from the insertion part 11. In this way, the protrusion is more adapted to the shape of the ear, and the snap-fit ​​end 1111 is less likely to be misaligned when connected to the ear.

[0066] Because the area from the auricle to the external auditory canal has a certain depth, in order for the Bluetooth headset 1000 to better fit the shape of the auricle and to ensure a more secure fit, [reference needed]. Figure 3 and Figure 5 In one embodiment, the snap-fit ​​end 1111 and the ear wing 31 are spaced apart in a third direction (as shown in the Y direction in the figure).

[0067] In a specific embodiment, the insertion part 11 includes a main body segment 112 and an extension segment 113. In a second direction, a sound outlet 15 is provided on one side of the main body segment 112, and the extension segment 113 is connected to the other side of the main body segment 112. The extension segment 113 extends in a direction away from the main body segment 112 in a first direction. The mounting base 12 is disposed on the side of the extension segment 113 away from the main body segment 112, and the snap-fit ​​end 1111 is disposed on the side of the main body segment 112 away from the mounting base 12. The main body segment 112 is used to install an audio driver unit. When the user wears the device, the snap-fit ​​end 1111 abuts against the side of the auricle of the outer ear near the external auditory canal. For example, the snap-fit ​​end 1111 abuts against the tragus and the entrance of the external auditory canal, so that the sound outlet 15 of the main body 112 is close to the entrance of the external auditory canal, thereby better transmitting sound. The extension section 113 abuts against the opposite side of the auricle of the outer ear away from the external auditory canal through the ear wing 31 at the mounting base 12. For example, the ear wing 31 abuts against the upper cavity wall of the concha, ultimately ensuring that the insertion part 11 is completely fixed and installed in the ear. In this way, on the one hand, the snap-fit ​​end 1111 and the ear wing 31 can each abut in a suitable position according to the shape of the ear, ensuring the stability of the connection and the wearing comfort after wearing, providing a better user experience; on the other hand, the sound outlet 15 on the main body 112 is designed to be close to the entrance of the external auditory canal, so that the sound can be transmitted to the ear more directly, reducing sound loss and interference, and providing a better listening experience.

[0068] Reference Figure 3 In one embodiment, the snap-fit ​​end 1111 and the ear wing 31 are symmetrically positioned opposite each other, and the center line of the sound outlet is aligned with the center line connecting the snap-fit ​​end 1111 and the ear wing 31. Thus, the Bluetooth headset 1000 adopts a completely symmetrical design, eliminating the need for users to distinguish between left and right ears, achieving a non-directional wearing experience. Users can freely switch between wearing sides without needing to identify the left or right ear, significantly improving product compatibility and ease of use.

[0069] Reference Figure 4 and Figure 8In one embodiment, the insertion portion 11 includes an inner shell 13 and an outer shell 14 sequentially arranged in a third-order direction. A portion of the main body segment 112 and the extension segment 113 jointly define the inner shell 13, and another portion of the main body segment 112 and the extension segment 113 jointly define the outer shell 14. The outer shell 14 covers the inner shell 13 and together with the inner shell 13 forms a snap-fit ​​end 1111. The outer shell 14 is detachably connected to the inner shell 13. This facilitates the installation of components into the insertion portion 11, improving assembly efficiency.

[0070] Refer again Figure 3 In one embodiment, the Bluetooth headset 1000 further includes an audio driver unit 50, which is disposed in the insertion portion and located between the control circuit board 40 and the inner shell 13. The control circuit board 40 is electrically connected to the audio driver unit 50. Thus, the overall layout of the Bluetooth headset 1000 is more compact, saving space.
