Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a headphone and headphone assembly that provides stable wearing. Background Technology

[0002] In related technologies, headphones typically have a touch area, which allows fingers to interact and operate to control the headphones. However, the touch area is usually located on the side of the ear stem, which makes it easy to pull the headphones out of the concha when interacting with the touch area during wear, resulting in insufficient stability. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a stable-wearing headset and headset assembly to improve the stability of headset wearing when interacting with the touch area with the finger.

[0004] To achieve the above objectives, one aspect of this application provides a pair of headphones that provide stable wearing, including:

[0005] The head includes an ear inlet for engaging with the concha of the outer ear;

[0006] The ear stem has its top end connected to the head. The outer wall of the ear stem facing away from the head is a first outer wall, and a touch area is formed on the first outer wall.

[0007] In the projection along the thickness direction of the ear stem, the projection of the touch area overlaps with the projection of the head, and the area of ​​the overlapping part is not less than 50% of the projected area of ​​the touch area.

[0008] In some embodiments, the touch area extends to both sides of the first outer wall along the width direction of the ear stem; or, the touch area is spaced apart from either side of the first outer wall along the width direction of the ear stem, wherein the thickness direction, width direction, and top-bottom direction of the ear stem are mutually perpendicular.

[0009] In some embodiments, the portion of the first outer wall excluding the touch area is a non-touch area, and the distance between the top of the non-touch area and the top of the touch area along the top-bottom direction is between 4mm and 6mm.

[0010] In some embodiments, the distance between the bottom end of the non-touch area and the bottom end of the touch area is between 8 mm and 12 mm.

[0011] In some embodiments, the earphone includes a flexible circuit board disposed within the ear stem. The flexible circuit board includes a touch area and an antenna area. The touch area and the antenna area are coplanar and parallel to the first outer wall. In a plane projection perpendicular to the thickness direction of the ear stem, at least a portion of the touch area overlaps with the touch area.

[0012] In some embodiments, the antenna region surrounds the outer periphery of the touch area and is spaced apart from the touch area.

[0013] In some embodiments, the minimum spacing between the touch area and the antenna area is between 0.5 mm and 1.2 mm.

[0014] In some embodiments, the extension dimension of the touch area along the top-bottom direction is between 10 mm and 16 mm.

[0015] In some embodiments, the extension dimension of the touch area along the width direction of the ear stem is between 1.6 mm and 2.5 mm, wherein the thickness direction, width direction, and top-bottom direction of the ear stem are mutually perpendicular.

[0016] In some embodiments, the ear stem includes a middle shell and a rear shell. The middle shell is connected to the head on one side along the thickness direction of the ear stem and to the rear shell on the other side. The middle shell has a receiving cavity. An opening is formed on the side of the middle shell opposite to the head along the thickness direction of the ear stem. The rear shell closes the opening. The flexible circuit board is disposed in the receiving cavity. The outer wall of the rear shell opposite to the ear insertion part along the thickness direction of the ear stem is the first outer wall.

[0017] In some embodiments, the earphone further includes at least one first connector, at least two second connectors, and a main board disposed within the receiving cavity. The flexible circuit board is disposed on the side of the main board near the opening along the thickness direction of the ear stem. The first connector is used to connect the touch area to the main board, and the second connector is used to connect the antenna area to the main board.

[0018] Another aspect of this application provides an earphone assembly, including an earphone case and earphones as described in any of the above embodiments that provide stable wearing, wherein the earphones are placed inside the earphone case.

[0019] The earphones provided in this application embodiment, by forming the touch area on the first outer wall, allow the user to apply pressure to the earphones by touching or sliding the touch area. This pressure is perpendicular to the plane of the auricle along the thickness direction of the ear stem, which improves the situation where the earphones are easily pulled out of the concha when the user touches the touch area, thus enhancing the stability of the earphones. Furthermore, in the projection along the thickness direction of the ear stem, the projection of the touch area overlaps with the projection of the head, and the area of ​​the overlap is not less than 50% of the projection area of ​​the touch area. Thus, more than half of the force applied by the finger to the earphones is directed towards the concha along the thickness direction of the ear stem, and the remaining force is also applied near the concha along the thickness direction of the ear stem. This improves the situation where, during the user's touch operation, the applied force deviates significantly from the position of the concha in the thickness direction of the ear stem, making it easy to pry the head out of the concha through leverage. It also facilitates user control of the earphones via the touch area. Attached Figure Description

[0026] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0027] In the description of the embodiments of this application, it should be noted that the terms "upper," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0029] A first aspect of this application provides a pair of headphones 10 that offer stable wear. Please refer to [link to relevant documentation]. Figures 1 to 4 The earphone 10 includes a head 11 and an ear stem 12. The head 11 includes an ear inlet 11a. The ear inlet 11a is used to engage with the concha of the outer ear. The tip of the ear stem 12 is connected to the head 11. The outer wall of the ear stem 12 opposite to the head 11 is a first outer wall 122a. A touch area 12a is formed on the first outer wall 122a. In the projection along the thickness direction of the ear stem 12, the projection of the touch area 12a overlaps with the projection of the head 11, and the area of ​​the overlapping portion is not less than 50% of the projected area of ​​the touch area 12a.

[0030] It should be noted that the earphone 10 in this application can be a wireless earphone or a wired earphone, and can be an in-ear earphone, a semi-in-ear earphone, an open-back earphone, etc., without any restrictions.

[0031] The concha, also known as the auricular cavity or auricular depression, is part of the outer ear. Specifically, it refers to a concave area of ​​the auricle (the cartilaginous part of the outer ear) near the center of the ear. It is located between the crus of the helix and the antihelix and is a relatively open space. The concha is a prominent anatomical landmark of the auricle and plays a certain acoustic role in the structure of the ear, helping to capture and guide sound into the ear canal.

[0032] The earphone 10 includes a head 11 and an ear stem 12. The head 11 refers to the part that houses the sound-producing unit. The ear inlet 11a of the head 11 cooperates with the concha cavity of the outer ear. The sound-producing unit located in the head 11 converts electrical signals into sound waves and emits them toward the concha cavity.

[0033] The top end of the ear stem 12 is connected to the head 11, and the bottom end of the ear stem 12 passes through the tragus and earlobe of the human ear along the top-bottom direction. In this way, the bottom end of the ear stem 12 can avoid the crus of the helix, the tragus and the earlobe on the periphery of the concha cavity, so that the ear-entry part 11a of the head 11 fits more closely with the concha cavity.

[0034] For example, the thickness direction of the ear stem 12 can be the thickness direction of the earphone 10, and the top and bottom directions are the length directions of the earphone 10 and the ear stem 12. For example, the ear stem 12 extends along the length direction.

[0035] For example, the thickness direction of the ear stem 12 is perpendicular to the plane of the auricle.

[0036] The outer wall of the ear stem 12 opposite to the head 11 is the first outer wall 122a. That is, the side of the head 11 opposite to the ear inlet 11a is connected to the side of the ear stem 12 opposite to the first outer wall 122a. The first outer wall 122a is away from the head 11 along the thickness direction.

[0037] A touch area 12a is formed on the first outer wall 122a. The touch area 12a refers to the interactive area where the user can control the earphone 10 through touch, swipe, or other operations. By forming the touch area 12a on the first outer wall 122a, when the user touches or swipes to contact the touch area 12a, the finger can apply a certain pressure to the earphone 10. The applied pressure is perpendicular to the plane of the auricle along the thickness direction of the ear stem 12, making it difficult for the finger to pull the earphone 10 out of the concha cavity, thus ensuring high wearing stability of the earphone 10.

[0038] Understandably, in some related technologies, the touch area is located on one side of the outer wall of the ear stem in the width direction, i.e., the side of the ear stem. In this embodiment, the touch area 12a is located on the first outer wall 122a, i.e., the front of the ear stem 12. This can improve the situation where, when touching the touch area 12a, the finger easily applies force along the width direction of the ear stem 12 to the earphone 10, thereby pulling the earphone 10 out of the concha cavity. This is beneficial to improving the stability of wearing the earphone 10. At the same time, it can reduce the probability of accidentally touching the touch area 12a when picking up the earphone 10, making it easier for the user to operate the touch area 12a.

[0039] For example, the width direction of the ear stem 12 is the width direction of the earphone 10, and the width direction is perpendicular to both the thickness direction and the top and bottom direction.

[0040] In the projection along the thickness direction of the ear stem 12, that is, on a plane perpendicular to the thickness direction of the ear stem 12, the projection of the touch area 12a overlaps with the projection of the head 11. In other words, the position range of the force applied by the finger to the earphone 10 is at least partially within the projection of the head 11. That is, most of the force applied by the finger to the earphone 10 can be applied towards the concha cavity along the thickness direction of the ear stem 12, and the remaining part can be applied near the concha cavity along the thickness direction of the ear stem 12. This can improve the situation where the position of the applied force is significantly deviated from the position of the concha cavity in the thickness direction of the ear stem 12 during the user's finger touch of the earphone 10, which makes it easy to pry the head 11 through the leverage effect and cause the head 11 to fall out of the concha cavity.

[0041] Meanwhile, the area of ​​the overlapping portion is not less than 50% of the projected area of ​​the touch area 12a. Here, the area of ​​the overlapping portion can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% of the projected area of ​​the touch area 12a, etc., and there is no restriction here.

[0042] The earphone 10 provided in this embodiment of the application forms a touch area 12a on the first outer wall 122a. When a user touches or slides the touch area 12a, their finger can apply a certain pressure to the earphone 10. The applied pressure is perpendicular to the plane of the auricle along the thickness direction of the ear stem 12. This can improve the situation where the finger can easily pull the earphone 10 out of the concha when touching the touch area 12a. While improving the stability of wearing the earphone 10, it can also reduce the probability of accidentally touching the touch area 12a when picking up the earphone 10, which is beneficial for the user to operate the touch area 12a. In addition, the projection along the thickness direction of the ear stem 12... In this design, the projection of the touch area 12a overlaps with the projection of the head 11, and the area of ​​the overlap is not less than 50% of the projected area of ​​the touch area 12a. Thus, more than half of the force applied by the finger to the earphone 10 is directed towards the concha cavity along the thickness direction of the ear stem 12, and the remaining force can also be applied near the concha cavity along the thickness direction of the ear stem 12. This can improve the situation where, during the process of the user touching the earphone 10, the position of the applied force deviates significantly from the position of the concha cavity in the thickness direction of the ear stem 12, making it easy to pry the head 11 through the leverage effect, thereby causing the head 11 to easily fall out of the concha cavity.

[0043] In some embodiments, please refer to Figure 1 The touch area 12a extends to both sides of the first outer wall 122a along the width direction of the ear stem 12. The thickness direction, width direction, and top-bottom direction of the ear stem 12 are mutually perpendicular.

[0044] For example, the width direction of the ear stem 12 is the width direction of the earphone 10.

[0045] In this embodiment, the touch area 12a extends to both sides of the first outer wall 122a along the width direction of the ear stem 12, which can increase the size of the touch area 12a in the width direction of the ear stem 12, which is beneficial for the user to perform touch operation.

[0046] In other embodiments, the touch area 12a and the first outer wall 122a are spaced apart along any one side edge of the ear stem 12 in the width direction, wherein the thickness direction, width direction and top-bottom direction of the ear stem 12 are perpendicular to each other.

[0047] In other words, the touch area 12a and the first outer wall 122a have a non-touch area 12b on either side of the ear stem 12 along the width direction. The restriction of the touch area 12a in the width direction of the ear stem 12 can correspondingly increase the antenna arrangement space, which is beneficial to improving the transmission quality of wireless signals.

[0048] In some embodiments, please refer to Figure 1 The portion of the first outer wall 122a excluding the touch area 12a is a non-touch area 12b. Along the top-bottom direction, the distance between the top of the non-touch area 12b and the top of the touch area 12a is between 4mm and 6mm.

[0049] For example, the distance between the top of the non-touch area 12b and the top of the touch area 12a is 4mm, 4.2mm, 4.5mm, 4.8mm, 5mm, 5.2mm, 5.5mm, 5.8mm or 6mm, etc., and is not limited here.

[0050] like Figure 1 As shown, the distance between the top of the non-touch area 12b and the top of the touch area 12a is represented by D1.

[0051] In this embodiment, by controlling the distance between the top of the non-touch area 12b and the top of the touch area 12a to between 4mm and 6mm, the non-touch area 12b has a certain extended area on the top side of the touch area 12a, which can provide arrangement space and transmission space for the antenna transmission, and is less likely to affect the antenna communication during the touch process.

[0052] In some embodiments, please refer to Figure 1 The distance between the bottom of the non-touch area 12b and the bottom of the touch area 12a is between 8mm and 12mm.

[0053] For example, the distance between the bottom end of the non-touch area 12b and the bottom end of the touch area 12a is 8mm, 8.2mm, 8.5mm, 8.8mm, 9mm, 9.2mm, 9.5mm, 9.8mm, 10mm, 10.5mm, 11mm, 11.5mm or 12mm, etc., and is not limited here.

[0054] like Figure 1 As shown, the distance between the bottom end of the non-touch area 12b and the bottom end of the touch area 12a is represented by D2.

[0055] In this embodiment, by controlling the distance between the bottom end of the non-touch area 12b and the bottom end of the touch area 12a to be between 8mm and 12mm, a certain non-touch area 12b is provided on the bottom side of the touch area 12a. Users can pinch the non-touch area 12b located at the bottom of the touch area 12a with their fingers, making it convenient for users to pick up and put down the earphone 10. At the same time, it is not easy for users to accidentally touch the touch area 12a during the process of picking up and putting down the earphone 10, thus improving the user experience.

[0056] In some embodiments, please refer to Figures 2 to 4 The earphone 10 includes a flexible circuit board 13. The flexible circuit board 13 is disposed within the ear stem 12. The flexible circuit board 13 includes a touch area 13a and an antenna area 13b. The touch area 13a and the antenna area 13b are coplanar and parallel to the first outer wall 122a. In a plane projection perpendicular to the thickness direction of the ear stem 12, at least a portion of the touch area 12a coincides with the touch area 13a.

[0057] It should be noted that the flexible printed circuit board (FPC) 13 is a type of printed circuit board made with polyimide or polyester film as the substrate, which has high reliability and high flexibility. It features high wiring density, light weight, thinness, and good bending performance.

[0058] The flexible circuit board 13 includes a touch area 13a and an antenna area 13b. The touch area 13a can specifically be a copper area on the flexible circuit board 13. The touch area 13a can have both tap and swipe touch functions. Swipe touch can be used to adjust the volume of the headset 10, while tap touch can be used to control functions such as answering / hanging up calls, pausing or resuming audio / video playback. The antenna area 13b can also be a copper area on the flexible circuit board 13. The antenna area 13b can be used to receive wireless signals, thereby enabling communication between the headset 10 and other devices.

[0059] The touch area 13a and the antenna area 13b are coplanar and parallel to the first outer wall 122a. Here, the touch area 13a and the antenna area 13b are integrated on the flexible circuit board 13, and the touch area 13a and the antenna area 13b are coplanar. That is to say, the touch area 13a and the antenna area 13b are combined to form a complete flexible circuit board 13. The touch area 13a and the antenna area 13b are not stacked along the thickness direction of the ear stem 12, which saves the stacking space along the thickness direction of the ear stem 12, thereby reducing the size of the ear stem 12 in the thickness direction, which is convenient for miniaturization design, can improve the appearance of the earphone 10, and at the same time, the production process is reduced, which can reduce the production cost and reduce the situation of poor consistency in the production process.

[0060] It is understandable that, in the thickness direction of the ear stem 12, the touch area 12a corresponds to the touch area 13a, and the non-touch area 12b corresponds to the antenna area 13b.

[0061] The touch area 13a and antenna area 13b of the flexible circuit board 13 are parallel to the first outer wall 122a. This includes situations where the touch area 13a and antenna area 13b of the flexible circuit board 13 are spaced apart or attached to the first outer wall 122a in the thickness direction of the ear handle 12. This facilitates the alignment of the touch area 13a and the touch area 12a in the thickness direction of the ear handle 12, making production and assembly more convenient.

[0062] In the plane projection along the thickness direction perpendicular to the ear stem 12, at least a portion of the touch area 12a coincides with the touch area 13a. The touch area 12a and the touch area 13a may completely coincide, or the touch area 13a may coincide with a portion of the touch area 12a. No limitation is made here.

[0063] In this embodiment, the touch area 13a and the antenna area 13b are coplanar and parallel to the first outer wall 122a, so that the touch area 13a and the antenna area 13b of the flexible circuit board 13 are directly facing the first outer wall 122a along the thickness direction of the ear stem 12. At the same time, the touch area 13a and the antenna area 13b are integrated on a flexible circuit board 13, which can simplify the internal stacking design of the earphone 10, save stacking space along the thickness direction of the ear stem 12, reduce production steps, reduce material costs and assembly costs, reduce inconsistencies during production, and improve the reliability of product production.

[0064] In some embodiments, please refer to Figures 2 to 4 The antenna region 13b surrounds the outer periphery of the touch region 13a and is spaced apart from the touch region 13a.

[0065] The antenna area 13b surrounds the outer periphery of the touch area 13a, that is, the touch area 13a is located inside the antenna area 13b. In this way, the arrangement area of ​​the antenna area 13b can be increased as much as possible, and the signal anti-interference capability and communication capability of the antenna area 13b can be improved.

[0066] The antenna area 13b and the touch area 13a are spaced apart, which can improve the performance of the antenna area 13b from being interfered with by the touch area 13a.

[0067] Here, the non-touch area 12b can correspond to the antenna area 13b and the total area of ​​the gap between the antenna area 13b and the touch area 13a.

[0068] In this embodiment, by surrounding the outer periphery of the touch area 13a with the antenna area 13b and spaced apart from the touch area 13a, the mutual interference between the antenna area 13b and the touch area 13a can be reduced. At the same time, it is beneficial to maximize the arrangement area of ​​the antenna area 13b and improve the signal anti-interference capability and communication capability of the antenna area 13b.

[0069] Of course, in other embodiments, the antenna region 13b may also be the outer periphery of a portion surrounding the touch region 13a; or, the antenna region 13b may be located on at least one side of the touch region 13a along the width direction of the ear stem 12, or the antenna region 13b may be located on at least one side of the touch region 13a along the top-bottom direction.

[0070] In some embodiments, please refer to Figures 2 to 4 The minimum spacing between the touch area 13a and the antenna area 13b is between 0.5mm and 1.2mm.

[0071] It is understandable that, since the external dimensions of the ear stem 12 in the width direction are limited and cannot be too large, the minimum spacing between the touch area 13a and the antenna area 13b here can refer to the spacing between the touch area 13a and the antenna area 13b in the width direction of the ear stem 12. By limiting the minimum spacing between the touch area 13a and the antenna area 13b in the width direction of the ear stem 12, the size of the flexible circuit board 13 in the width direction of the ear stem 12 can be controlled, thereby reducing the size of the ear stem 12 in the width direction and reducing the impact of the size of the flexible circuit board 13 in the width direction of the ear stem 12 on the appearance of the ear stem 12.

[0072] For example, the minimum spacing between the touch area 13a and the antenna area 13b is 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm or 1.2mm, etc., and is not limited here.

[0073] like Figure 2 and Figure 4 As shown, the minimum spacing between the touch area 13a and the antenna area 13b is denoted by D3.

[0074] By limiting the minimum spacing between the touch area 13a and the antenna area 13b to between 0.5mm and 1.2mm, the size of the flexible circuit board 13 in the width direction of the ear stem 12 can be reduced, thereby reducing the size of the ear stem 12 in the width direction and improving the appearance of the ear stem 12.

[0075] Furthermore, the minimum spacing between the touch area 13a and the antenna area 13b is between 0.5mm and 1mm.

[0076] In some embodiments, please refer to Figures 2 to 4 The extension dimension of the touch area 13a along the top and bottom direction is between 10mm and 16mm.

[0077] For example, the extension dimension of the touch area 13a along the top and bottom direction is 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or 16mm, etc., and there is no limitation here.

[0078] like Figure 4 As shown, the extension dimension of the touch area 13a along the top and bottom direction is represented by D4.

[0079] Thus, by setting the extension dimension of the touch area 13a along the top and bottom direction between 10mm and 16mm, the length of the touch area 13a on the flexible circuit board 13 can be controlled, allowing the user to slide and control the earphone 10 along this length while also reducing the extension dimension of the ear stem 12 in the top and bottom direction, thus improving the appearance of the ear stem 12.

[0080] In some embodiments, please refer to Figures 2 to 4 The extension dimension of the touch area 13a along the width direction of the ear stem 12 is between 1.6 mm and 2.5 mm. The thickness direction, width direction, and top-bottom direction of the ear stem 12 are mutually perpendicular.

[0081] For example, the extension dimension of the touch area 13a along the width direction of the ear stem 12 is 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm or 2.5mm, etc., and there is no limitation here.

[0082] like Figure 2 and Figure 4 As shown, the extension dimension of the touch area 13a along the width direction of the ear stem 12 is represented by D5.

[0083] Here, by setting the extension dimension of the touch area 13a along the width direction of the ear stem 12 to between 1.6mm and 2.5mm, space can be left on both sides of the flexible circuit board 13 along the width direction of the ear stem 12 for the arrangement of the antenna area 13b and the spacing distance between the antenna area 13b and the touch area 13a. This helps to reduce the size of the ear stem 12 in the width direction and improve the appearance of the product.

[0084] In some embodiments, please refer to Figures 1 to 4 The ear stem 12 includes a middle shell 121 and a rear shell 122. The middle shell 121 is connected to the head 11 on one side along the thickness direction of the ear stem 12, and to the rear shell 122 on the other side. The middle shell 121 has a receiving cavity 121a. An opening 121b is formed on the side of the middle shell 12 opposite to the head 11 along the thickness direction of the ear stem 12.
