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 9 (as shown in P) and flexible holding block (such as Figure 9 As shown in the U), the main body includes snap-fit ​​terminals arranged opposite each other (such as...). Figure 9 As shown in Figure I, the flexible retaining block is installed at the mounting end. The earphone is secured to the user's ear by engaging with the flexible retaining block at the mounting end. This enhances the friction between the Bluetooth earphone and the ear, effectively preventing the earphone from falling out.

[0004] However, in the above structure, after the flexible holding block is compressed, the different directions of force will cause uneven distribution of deformation inside the holding block. This is mainly manifested in the uneven distribution of deformation in the middle part of the flexible holding block (such as...). Figure 9 As shown by L in the diagram, the part opposite to the locking end has its middle section located in the direction of force, thus allowing it to deform under sufficient force. In contrast, the two sides of the flexible locking block (as shown by L in the diagram) Figure 9 As shown in K), due to the different direction of force, the force is smaller, resulting in insufficient deformation on both sides, which cannot effectively adapt to the shape of the ear. Moreover, during prolonged wear, this insufficient deformation will cause the sides to put pressure on the contact points with the ear, reducing wearing comfort. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a Bluetooth headset to solve the problem that although the new form of headset in the prior art has good wearing stability, its compatibility is insufficient, which affects the user experience.

[0006] The Bluetooth headset provided in this embodiment of the utility model includes:

[0007] The housing includes an insertion portion for insertion into a user's ear, the insertion portion including an outer peripheral surface that is covered by the ear, the outer peripheral surface including a mounting end and a snap-fit ​​end that are spaced apart and opposite to each other in a first direction;

[0008] The retaining block includes a connecting part and a flexible supporting part. The connecting part passes through the mounting end, and the flexible supporting part is connected to the connecting part and exposed on the outer peripheral surface of the insertion part, so that the flexible supporting part can cooperate with the retaining end to limit the installation of the Bluetooth headset.

[0009] The outer contour of the flexible abutment is larger than the outer contour of the connecting part, so as to form a gap space between the flexible abutment and the outer peripheral surface.

[0010] In one embodiment, the flexible abutment includes a first connecting segment and a second connecting segment. One end of the first connecting segment is connected to the connecting portion, and one end of the second connecting segment is connected to the end of the first connecting segment connected to the connecting portion and the connecting portion. The other ends of the first connecting segment and the other ends of the second connecting segment extend in opposite directions.

[0011] In one embodiment, the second connecting segment is symmetrically arranged with the first connecting segment, and both the first connecting segment and the second connecting segment are bent and extended along the outer peripheral surface toward the snap-fit ​​end.

[0012] In one embodiment, the cross-section of the flexible abutment is circular.

[0013] In one embodiment, the snap-fit ​​end is a protrusion disposed on the outer peripheral surface of the insertion portion, and the protrusion has a gradually narrowing trend in the direction away from the insertion portion.

[0014] In one embodiment, the latching end and the holding block are spaced apart in a second direction, and the second direction is at an angle to the first direction.

[0015] In one embodiment, the insertion portion includes a main body segment and an extension segment. In the second direction, a sound outlet 1131 is provided on one side of the main body segment, and the extension segment is connected to the other side of the main body segment. The extension segment extends away from the main body segment in the first direction and has a gradually narrowing trend. The mounting end is disposed on the side of the extension segment away from the main body segment.

[0016] In one embodiment, the connecting portion is slidably connected to the mounting end in the first direction, and the retaining block further includes an elastic structure connected to the side of the connecting portion away from the flexible abutment portion. The elastic structure is used to adjust the distance between the retaining block and the retaining end.

[0017] In one embodiment, the mounting end is provided with a sliding groove, the connecting part is slidably connected to the sliding groove in the first direction, the groove wall of the sliding groove is provided with a limiting groove, the limiting groove extends in the first direction, and the connecting part is provided with a limiting block on the side away from the flexible abutment, the limiting block is accommodated in the limiting groove.

[0018] In one embodiment, the connecting part is further provided with a retaining post on the side opposite to the flexible abutment part, and the elastic structure is a spring fitted on the retaining post, the spring being clamped between the connecting part and the bottom of the sliding groove.

[0019] Compared with the prior art, the Bluetooth headset provided by this utility model has the following advantages: the Bluetooth headset not only has good wearing stability and is suitable for various types of sports scenarios, but also has stronger adaptability and wearing comfort.

[0020] Specifically, the flexible abutment of the retaining block is exposed outside the insertion part. This flexible abutment, in conjunction with the locking end, secures the Bluetooth headset to the user's ear. Since the retaining block and the locking end are positioned opposite each other in the first direction of the insertion part, after the Bluetooth headset is inserted, the locking end and retaining block on both sides of the insertion part provide support, resulting in a more balanced force on the Bluetooth headset in the ear and increased friction between the Bluetooth headset and the ear. This allows the Bluetooth headset to be worn more securely. Furthermore, because the outer contour of the flexible abutment of the retaining block is larger than the outer contour of the connecting part, a gap is formed between the flexible abutment and the outer peripheral surface. After the user wears the headset, this gap makes the sides of the flexible abutment more easily deformable under stress. Even under small forces, the sides of the flexible abutment can fully deform according to the shape of the part in contact with the ear using the gap, increasing the fit to the ear, adapting to different ear types, reducing pressure concentration, and minimizing discomfort after wearing. Therefore, the Bluetooth headset of this application not only has good connection stability and comfort but also stronger adaptability. Attached Figure Description

[0038] 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.

[0039] This utility model embodiment provides a Bluetooth headset 1000, such as... Figure 1 and Figure 2As shown, the Bluetooth headset 1000 includes a housing 10 and a retaining block 20. The housing 10 includes an insertion portion 11 for insertion into a user's ear. The insertion portion 11 includes an outer peripheral surface that is covered by the ear. The outer peripheral surface includes a first direction (e.g., Figure 1 The mounting end 111 and the latching end 112 are positioned opposite each other and spaced apart (as shown in the X direction). The latching block 20 includes a connecting part 21 and a flexible abutment part 22. The connecting part 21 passes through the mounting end 111, and the flexible abutment part 22 is connected to the connecting part 21 and exposed on the outer surface of the insertion part 11, so that the flexible abutment part 22 can cooperate with the latching end 112 to limit the installation of the Bluetooth headset 1000. The outer contour of the flexible abutment part 22 is larger than the outer contour of the connecting part 21, so as to form a gap space 30 between the flexible abutment part 22 and the outer peripheral surface. This application can solve the problem that although the new form of headset in the prior art has good wearing stability, its adaptability is insufficient, which affects the user experience. The Bluetooth headset 1000 not only has good wearing stability and is suitable for various types of sports scenarios, but also has stronger adaptability and wearing comfort.

[0040] Specifically, the flexible abutment portion 22 of the retaining block 20 is exposed outside the insertion portion 11. The flexible abutment portion 22 can engage with the retaining end 112 to secure the Bluetooth headset 1000 to the user's ear. Since the retaining block 20 and the retaining end 112 are positioned opposite each other in the first direction of the insertion portion 11, after the Bluetooth headset 1000 is secured, the retaining end 112 and the retaining block 20 on both sides of the insertion portion 11 provide support. This makes the Bluetooth headset 1000 more evenly stressed in the ear and enhances the friction between the Bluetooth headset 1000 and the ear, thus allowing the Bluetooth headset 1000 to be worn more securely in the ear. Furthermore, since the outer contour of the flexible support portion 22 of the retaining block 20 is larger than the outer contour of the connecting portion 21, a gap space 30 is formed between the flexible support portion 22 and the outer peripheral surface. After the user wears it, the existence of the gap space 30 makes the two sides of the flexible support portion 22 more easily deformed under force. That is, even if the two sides of the flexible support portion 22 are subjected to a small force, they can fully deform according to the shape of the part in contact with the ear using the gap space 30 to increase the fit with the ear, adapt to different types of ears, reduce pressure concentration, and reduce discomfort after wearing. It can be seen that the Bluetooth headset 1000 of this application not only has good connection stability and comfort, but also has stronger adaptability.

[0041] Reference Figure 3 and Figure 4In one embodiment, the flexible support portion 22 includes a first connecting segment 221 and a second connecting segment 222. One end of the first connecting segment 221 is connected to the connecting portion 21, and one end of the second connecting segment 222 is connected to the end of the first connecting segment 221 connected to the connecting portion 21 and the connecting portion 21. The other ends of the first connecting segment 221 and the second connecting segment 222 extend in opposite directions. Thus, both the first connecting segment 221 and the second connecting segment 222 can deform according to the shape of the corresponding contact area with the ear through the gap space 30, further increasing the fit. Furthermore, the first connecting segment 221 and the second connecting segment 222 can deform according to the shape of the contact area, which not only further increases the contact area with the ear and improves the connection stability after wearing, but also helps to distribute pressure, effectively reducing pressure concentration after wearing and reducing discomfort.

[0042] Preferably, the second connecting segment 222 is symmetrically arranged with the first connecting segment 221, so that when the ear is subjected to reaction force, the force is more evenly distributed, increasing connection stability and comfort.

[0043] There are many ways to arrange the shapes of the first connecting segment 221, the second connecting segment 222, and the connecting part 21. For example, the overall shape of the retaining block 20 can be T-shaped, Y-shaped, or other special shapes, which are not limited here. Preferably, in this application, both the first connecting segment 221 and the second connecting segment 222 are bent and extended along the outer peripheral surface towards the retaining end. In this way, the bent and extended first connecting segment 221 and the second connecting segment 222 can better deform after contacting the ear and being subjected to force, and the bent and extended first connecting segment 221 and the second connecting segment can better conform to the curved shape of the ear, further increasing the contact area and increasing the wearing stability. Specifically, the overall shape of the retaining block 20 is similar to that of a ship's anchor.

[0044] In one embodiment, the other end of the first connecting segment 221 is hemispherical; similarly, the other end of the second connecting segment 222 is also hemispherical. Thus, the other ends of both the first connecting segment 221 and the second connecting segment 222 are hemispherical, which can prevent discomfort in the ear during wearing and prevent scratching of the ear skin.

[0045] In one embodiment, the first connecting segment 221, the second connecting segment 222, and the connecting portion 21 are integrally formed. This reduces the number of parts and facilitates installation.

[0046] In the above embodiments, the cross-section of the flexible support portion 22 can be of any shape and is not limited thereto. Preferably, the cross-section of the flexible support portion 22 is circular, so that the surface of the flexible support portion 22 has no sharp edges, the surface of the flexible support portion 22 is smoother, which can effectively increase the contact area with the ear, make the pressure more evenly distributed, reduce the pressure concentration on the ear, reduce the discomfort of the ear when wearing, and increase the wearing comfort.

[0047] In one embodiment, the retaining block 20 is made of a soft material. This improves user comfort when wearing the device. Specifically, the retaining block 20 can be made of silicone. It is understood that the retaining block 20 can also be a rubber-coated component, improving user comfort while maintaining overall structural strength.

[0048] Reference Figure 5 - Figure 7 In one embodiment, the snap-fit ​​end 112 is a protrusion 1121 provided on the outer peripheral surface of the insertion portion 11, and the protrusion 1121 has a gradually narrowing tendency in the direction away from the insertion portion 11. In this way, the protrusion 1121 is more adapted to the shape of the ear, and the snap-fit ​​end 112 is less likely to be misaligned when connected to the ear.

[0049] Preferably, the protrusion 1121 has a second curved surface. In this way, the second curved surface can increase the contact area with the ear, so that the Bluetooth headset 1000 is more firmly fixed on the ear; on the other hand, the surface is smoother, avoiding user discomfort after wearing and improving wearing comfort.

[0050] 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 6 and Figure 7 In one embodiment, the latching end 112 and the latching block 20 are in a second direction (e.g., Figure 6 The second direction is perpendicular to the first direction, as shown in the Y direction.

[0051] In a specific embodiment, the insertion part 11 includes a main body segment 113 and an extension segment 114. In a second direction, a sound outlet 1131 is provided on one side of the main body segment 113, and the extension segment 114 is connected to the other side of the main body segment 113. The extension segment 114 extends in a direction away from the main body segment 113 in a first direction. The mounting end 111 is provided on the side of the extension segment 114 away from the main body segment 113, and the snap-fit ​​end 112 is provided on the side of the main body segment 113 away from the mounting end 111. The main body segment 113 is used to install the audio driver unit. 50. After the user wears the device, the locking end 112 abuts against the side of the auricle of the outer ear near the external auditory canal. For example, the locking end 112 abuts against the tragus and the entrance of the external auditory canal, so that the sound outlet 1131 of the main body 113 is close to the entrance of the external auditory canal, thereby better transmitting sound. The extension section 114 abuts against the opposite side of the auricle of the outer ear away from the external auditory canal through the retaining block 20 at the mounting end 111. For example, the retaining block 20 abuts against the upper wall of the concha cavity, ultimately ensuring that the insertion part 11 is completely fixed and installed in the ear. In this way, on the one hand, the locking end 112 and the retaining block 20 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 1131 on the main body 113 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.

[0052] Reference Figure 3 In one embodiment, the insertion portion 11 includes an inner shell 115 and an outer shell 116 sequentially disposed in a second direction. A portion of the main body segment 113 and the extension segment 114 jointly define the inner shell 115, and another portion of the main body segment 113 and the extension segment 114 jointly define the outer shell 116. The outer shell 116 covers the inner shell 115 and together with the inner shell 115 forms an mounting end 111 and a snap-fit ​​end 112. The outer shell 116 is detachably connected to the inner shell 115. This facilitates the installation of components into the insertion portion 11 and improves assembly efficiency.

[0053] Refer again Figure 3 In one embodiment, the Bluetooth headset 1000 further includes a control circuit board 40, which is installed in the insertion part 11 and located on the same side as the audio driver unit 50 and the retaining block 20. The control circuit board 40 is electrically connected to the audio driver unit 50. In this way, the overall layout of the Bluetooth headset 1000 is more compact and saves space.

[0054] To further enhance the compatibility of this Bluetooth headset 1000, refer to Figure 4 - Figure 5In one embodiment, the connecting portion 21 is slidably connected to the mounting end 111 in a first direction. The retaining block 20 further includes an elastic structure 23, which is connected to the side of the connecting portion 21 away from the flexible abutment portion 22. The elastic structure 23 is used to adjust the distance between the retaining block 20 and the retaining end 112. In this way, an adaptive connection between the Bluetooth headset 1000 and the ear is achieved.

[0055] There are many ways to set the elastic structure 23. In one embodiment, the elastic structure 23 is made of a material with elastic deformation, such as rubber. When the clamping block is subjected to force, the elastic structure 23, due to its elastic deformation properties, stores energy under pressure, shortens the distance between the clamping block 20 and the clamping end 112, and releases energy and resets when no force is applied.

[0056] In another embodiment, the elastic structure 23 is a spring 231, which is used to compress and store energy when the retaining block 20 is pressed. The spring 231 causes the retaining block 20 to always tend to move outward towards the mounting end 111, and when the retaining block 20 comes into contact with the ear, it is compressed and stores energy, shortening the distance between the retaining block 20 and the locking end 112, and releasing energy and resetting when no force is applied. Specifically, the number of springs 231 can be adjusted by those skilled in the art according to the actual required elastic force, and is not limited here. In this way, both of the above embodiments can realize the adaptation and fixation of the Bluetooth headset 1000 with the ear, and after the Bluetooth headset 1000 is removed, it drives the retaining block 20 to reset, realizing the adaptive fit and connection between the Bluetooth headset 1000 and the ear.

[0057] Reference Figure 4 and Figure 8 In one embodiment, a retaining post 212 is provided on the side of the connecting portion 21 facing away from the flexible supporting portion 22. The spring 231 is fitted onto the retaining post 212 and clamped between the connecting portion 21 and the bottom of the sliding groove 1111. In this way, the retaining post 212 can restrict the bending of the spring 231, so that the spring 231 can fully store energy when compressed, thereby improving the stability of the retaining block 20 after its energy is released.

[0058] Reference Figure 5In one embodiment, the mounting end 111 is provided with a sliding groove 1111, and the connecting part 21 is slidably connected in the sliding groove 1111 in a first direction. A limiting groove 1112 is provided on the groove wall of the sliding groove 1111, extending in the first direction. A limiting block 211 is provided on the side of the connecting part 21 away from the flexible abutment part 22, and the limiting block 211 is accommodated in the limiting groove 1112. Specifically, the sliding groove 1111 can limit the connecting part 21 of the holding block 20 and provide guidance for it, so that the holding block 20 can always maintain movement along the first direction. The cooperation between the limiting groove 1112 and the limiting block 211 can limit the movement distance of the holding block 20 in the first direction and prevent the holding block 20 from detaching from the mounting end 111, improving the reliability and stability of the connection between the two.

[0059] Preferably, limiting blocks 211 are provided on both sides of the connecting part 21, and two limiting grooves 1112 are provided on the sliding groove 1111. Each holding block 20 is accommodated in each limiting groove 1112 to improve the limiting effect on the holding block 20 and prevent the holding block 20 from shifting position during movement.

[0060] Reference Figure 5 In one embodiment, 5a of the above, in the stored state, the flexible support portion 22 can move to fit against the outer peripheral surface of the insertion portion 11 to eliminate the gap space 30, reduce the space occupied by the outside, and make it easier for the Bluetooth headset 1000 to be placed in the charging case.

[0061] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
