Description

Technical Field

[0001] The present invention relates to the field of audio playback equipment, and further to an ear-clip earphone and an ear-clip earphone design method. Background Art

[0002] At present, users often experience discomfort or inability to fit the ear contour when wearing some clip-on earphones, resulting in a poor user experience. In addition, the clamping and fixing design of some clip-on earphones is also relatively random, which may cause the clamping to be too forceful, causing discomfort to the user's ears, or may cause unstable clamping, causing the earphones to fall off.

[0003] In summary, an ear-clip type headset is needed to solve the above problems. Summary of the invention

[0004] In view of the above technical problems, the purpose of the present invention is to provide an ear-clip earphone and an ear-clip earphone design method, so that users can wear the ear-clip earphone more comfortably, and the earphone can better fit the human ear structure, has high adaptability and is not easy to fall off.

[0005] In order to achieve the above-mentioned purpose, the present invention provides an earphone with a clip-on design, comprising: an earphone body and a clamping portion, wherein the earphone body comprises a sound outlet portion and a fixing portion connected to the sound outlet portion, wherein the sound outlet portion is suitable for being placed in the concha cavity, and the sound outlet hole of the sound outlet portion faces the ear canal, the fixing portion comprises a curved section, and the tail section of the fixing portion faces the same direction as the extension direction of the sound outlet portion, so that the curved section and the sound outlet portion form an adaptation cavity to adapt to the ear contour; the clamping portion is movably connected to an end of the fixing portion away from the sound outlet portion, so that when the earphone with a clip-on design is worn, the clamping portion can move toward the sound outlet portion and abut against the back of the ear, so that the fixing portion and the clamping portion can wrap a part of the ear together.

[0006] It should be noted that, through the joint action of the fixing part and the clamping part, the earphones can wrap and fix the human ears well. At the same time, since the fixing part is set to a curved shape, the fixing part will not press on the ears, and the ears of users will not feel burdened when wearing them, thereby improving the experience.

[0007] In some embodiments, the side of the fixing portion close to the auricle is a smooth curved surface, and when the ear clip-on earphone is worn, the antihelix is ​​located on the inner side of the smooth curved surface.

[0008] Among them, the smooth arc surface design on one side of the fixing part can facilitate processing and production, and when taking the clip-on earphone, the fingers can directly pinch this part, which is also convenient for users to take it. In addition, this smooth arc surface has a stronger adaptability to the antihelix of the human ear, which can improve the comfort of wearing the earphone.

[0009] In some embodiments, the clamping portion includes a connecting end and a pressing end, the connecting end is rotatably connected to the fixing portion via a rotating shaft, and the contour of the pressing end matches the contour of the back of the ear, so that when the clip-on earphone is worn, the pressing end can fit against the back of the ear.

[0010] Here, the clamping part and the fixing part are rotatably connected by a rotating shaft. Therefore, when wearing the earphones, the user only needs to rotate the clamping part toward the back of the ear to complete the clamping and fixing. It is very easy to use, and because the contour of the clamping end of the clamping part is compatible with the contour of the back of the ear, the clamping performance is very good, and no gap will be generated to cause shaking or deviation during wearing of the earphones.

[0011] In some embodiments, the connecting end and the fixing portion are both provided with corresponding receiving end surfaces, so that after the connecting end is rotated by a preset angle, the two receiving end surfaces can fit together, and the clamping portion and the fixing portion form a smooth earphone tail section.

[0012] It should be noted that the design of the connecting end surface can be used to limit the rotation of the connecting end. When the corresponding connecting end surfaces are fitted, the connecting end cannot continue to rotate due to the lack of excess gap, so that the connecting end is fixed in this position. In addition, when the clamping part and the fixing part form a smooth ear-clip earphone tail section, it is also very convenient for storage, and the user does not need to clamp and fix it when wearing it in some scenarios, which can realize the diversification of earphone wearing forms and styles.

[0013] In some embodiments, when the clamping portion moves to the extreme position, the distance between the clamping portion and the sound output portion is a first preset interval, and the first preset interval matches the distance between the concha cavity and the back of the ear.

[0014] The distance between the concha cavity and the back of the ear can be understood as the thickness of the human ear. When wearing the clip-on earphone, if the first preset interval does not match the thickness of the human ear, it may cause the clamping portion to exert too much pressure on the ear, causing the clip-on earphone to damage the ear, or the pressure may be too small, making the clamping portion unable to clamp the ear, causing the clip-on earphone to fall off, resulting in property loss to the user.

[0015] In some embodiments, the first preset interval is no greater than 4 mm.

[0016] In some embodiments, the distance between two sides of the adaptation cavity is a second preset interval, and the second preset interval matches the distance from the anti-helix to the helix of the human ear.

[0017] Among them, the distance from one helix to another helix is ​​adapted to the second preset interval, so that the width of the fixing part is very reasonable, so that when the fixing part wraps the auricle, it will not produce a sense of oppression thereon, making the clip-on earphones very comfortable and secure when worn.

[0018] In some embodiments, the second preset interval ranges from 6 to 15 mm.

[0019] Another aspect of the present invention also provides a method for designing a clip-on earphone, comprising the steps of:

[0020] Acquire the contour data of the concha cavity, and design a sound output part according to the contour data of the concha cavity, so that the contour of the sound output part corresponds to the contour of the concha cavity;

[0021] A fixing portion is arranged at the tail section of the sound-emitting portion, and the fixing portion is in a curved shape, so that the fixing portion and the sound-emitting portion are surrounded by each other to form an adaptation cavity to adapt to the contour of the ear;

[0022] Acquire the back of the ear contour data, design a clamping part according to the back of the ear contour data, and movably connect the clamping part with the fixing part at one end away from the sound-emitting part, so that the clamping part can abut against the back of the ear for clamping and fixing, so that part of the ear can be wrapped by the clamping part and the fixing part together.

[0023] It should be noted that it is necessary to obtain the data of the concha cavity contour, the back of the ear contour, etc., and then design the sound-emitting structure based on the corresponding data, so that the ear-clip earphones can be highly adaptable to the human ear, and data can be collected through population surveys, so that the designed ear-clip earphones can conform to the ear contours of a large part of the population, which has good economic benefits.

[0024] In some embodiments, the fixing portion is provided at the end of the sound output portion, specifically comprising:

[0025] Acquiring contour data of the antihelix and the helix, and setting the contour of the fixing portion close to the ear according to the contour data of the antihelix and the helix;

[0026] The distance data from the antihelix to the helix is ​​obtained, and the length of the fixing portion is set according to the distance data from the antihelix to the helix, so that the fixing portion can surround a portion of the antihelix and the helix at the same time.

[0027] It should be noted here that when wearing the clip-on earphones, the fixing portion surrounds part of the antihelix and the auricle, so the design of the fixing portion is very important. If the design of the fixing portion is not appropriate, it is easy for the earphones to compress the ears, or the earphones are very loose when worn, which affects safety and is not beautiful.

[0028] In some embodiments, the back of the ear contour includes a back of the ear groove contour and a helix contour, and designing a clamping portion according to the back of the ear contour data specifically includes:

[0029] Acquire the dorsal ear groove contour data, and design the pressing end contour of the clamping portion according to the dorsal ear groove contour data, so that the pressing end can abut against and fit the dorsal ear groove;

[0030] The helix contour data is obtained, and the ear-contacting surface contour of the clamping portion is designed according to the helix contour data, wherein the ear-contacting surface is the surface of the clamping portion close to the helix, so that the pressing end contour and the ear-contacting surface contour are smoothly transitioned, and the clamping portion forms a continuous arc surface that can fit the back of the ear contour.

[0031] Among them, the design of the clamping part is mainly based on the contour of the dorsal ear groove and the helix. Such a design enables the clamping part to fit the contour of the back of the ear very well when clamped, making the wearing process of the clip-on earphones more comfortable.

[0032] In some embodiments, the designing of a clamping portion according to the back-of-ear contour data further includes:

[0033] The distance data from the concha cavity to the back of the ear is obtained, and the minimum interval between the pressing end and the sound output part is set according to the distance data from the concha cavity to the back of the ear, so that when the clip-on earphone is worn, the minimum interval can match the thickness of the human ear.

[0034] The clamping part is designed to adapt to the thickness of human ears. When the user wears the clip-on earphones, the clamping end and the sound-emitting part just clamp the ears. If the clamping is too tight or too loose, it will lead to a bad user experience. Therefore, these problems can be avoided by designing the minimum interval to adapt to the thickness of the ears.

[0035] Compared with the prior art, the ear-clip earphone and the ear-clip earphone design method provided by the present invention have the following beneficial effects:

[0036] 1. The present invention provides an ear-clip earphone, wherein the fixing portion and the clamping portion are capable of forming a clamping space, and can wrap around a portion of the ear, so that the user is very comfortable when wearing the ear-clip earphone.

[0037] 2. In the ear-clip earphone provided by the present invention, the relative state of the fixing part and the clamping part can be adjusted by setting a receiving end surface, so that the shape and wearing method of the earphone can be adjusted according to specific circumstances.

[0038] 3. In the ear-clip earphone provided by the present invention, the contours of the fixing part and the clamping part are highly adapted to the ear contour, which can avoid the problem of the earphone being loose or the earphone being pressed too tightly when fixed, thereby improving reliability.

[0039] 4. The ear-clip earphone design method provided by the present invention can design the ear-clip earphone's ear-clip contour by acquiring contour data of various parts of the ear. It is very targeted at factors such as the ear-clip size, thereby ensuring a reasonable ear-clip contour size of the ear-clip earphone. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0056] In one embodiment, the reference specification Figure 1A clip-on earphone and a clip-on earphone design method provided by the present invention are described. The clip-on earphone provided by the present invention has an ear-clip space that is highly adapted to the ear contour, so that the user can be very comfortable when clamping the clip-on earphone, and the earphone is firm and not easy to fall off.

[0057] Reference Manual Attached Figure 1 The present invention provides an earphone with a clip-on design, comprising an earphone body and a clamping portion 3. The earphone body comprises a sound outlet portion 1 and a fixing portion 2 connected to the sound outlet portion 1. The sound outlet portion 1 is suitable for being placed in the concha cavity, and a sound outlet hole 10 of the sound outlet portion 1 faces the ear canal. The fixing portion 2 is curved, and the tail section of the fixing portion 2 faces the same direction as the extension direction of the sound outlet portion 1, so that the curved section of the fixing portion 2 and the sound outlet portion 1 form an adaptation cavity to adapt to the ear contour; the clamping portion 3 is movably connected to an end of the fixing portion 2 away from the sound outlet portion 1, so that when the earphone with a clip-on design is worn, the clamping portion 3 moves toward the direction of the sound outlet portion 1 and abuts against the back of the ear, so that the fixing portion 2 and the clamping portion 3 can wrap a part of the ear together.

[0058] It should be noted that, through the joint action of the fixing part 2 and the clamping part 3, this kind of ear-clip earphone can wrap and fix the ear of the human body well. At the same time, since the fixing part 2 is set to a curved shape, the fixing part 2 will not press on the ear, and the user's ear will not feel any burden when wearing it, thereby improving the experience.

[0059] When wearing headphones, please refer to the instructions. Figure 5 and Figure 6 The sound-emitting part 1 is first placed in the concha cavity, the fixing part 2 extends along the ear canal in the direction of the concha cavity and wraps the antihelix, and then the back of the ear is clamped by the clamping part 3 to achieve fixation. The wearing method is very simple, and because the back of the ear is clamped from the side, it avoids pressing on the earrings, ear studs and the like worn by the user to a certain extent, which is more reliable.

[0060] In one embodiment, based on the above embodiment, the side of the fixing portion 2 close to the auricle is a smooth arc surface, and when the clip-on earphone is worn, the antihelix is ​​located on the inner side of the smooth arc surface.

[0061] Among them, the smooth arc surface design of the fixing part 2 close to the auricle can facilitate processing and production, and the fingers can directly pinch this part when taking the clip-on earphone, which is also convenient for users to take it. In addition, this smooth arc surface has a stronger adaptability to the antihelix of the human ear, which can improve the comfort of wearing the earphone.

[0062] However, it should be noted that the smooth curved surface design here is a preferred implementation mode, and it can also be set to a concave and convex surface, or some materials such as silicone pads and soft rubber can be added to the smooth curved surface to improve comfort and prevent oil or sweat in the ears from slipping when wearing headphones.

[0063] In one embodiment, the reference specification Figure 2 and Figure 3 The clamping portion 3 includes a connecting end and a pressing end 32. The connecting end is rotatably connected to the fixing portion 2 via a rotating shaft. The contour of the pressing end 32 matches the contour of the back of the ear, so that when the clip-on earphone is worn, the pressing end 32 can fit the back of the ear.

[0064] Here, the clamping part 3 and the fixing part 2 are rotatably connected by a rotating shaft. Therefore, when wearing the earphone, the user only needs to rotate the clamping part 3 toward the back of the ear to complete the clamping and fixing. It is very easy to use, and because the contour of the clamping end 32 of the clamping part 3 is compatible with the contour of the back of the ear, the clamping performance is very good, and no gap will be generated to cause shaking or deviation during wearing of the earphone.

[0065] Preferably, refer to the specification sheet. Figure 3 and Figure 4 The fixing part 2 is provided with a rotating column head 21, and the connecting end is a hollow ring 31 corresponding to the rotating column head. The rotating shaft passes through the through holes in the center of the rotating column head 21 and the hollow ring 31 at the same time to make the two rotatably connected. When the clamping part 3 rotates, it rotates around the rotating shaft.

[0066] A transition groove 300 is disposed on one side of the clamping portion 3 close to the rotating column head 21 , and the rotating column head 21 can be accommodated in the transition groove 300 .

[0067] This arrangement first reduces the contact between the rotating column head 21 and the outside air or water vapor, making it less likely to be damaged. It also makes the earphone more beautiful and more integrated as a whole. Moreover, due to the matching of the transition groove 300, when the clamping part 3 rotates, the hollow ring 31 and the rotating column head 21 are not likely to collide, which can improve reliability to a certain extent.

[0068] On the basis of the above-mentioned embodiment, the contact surface between the rotating column head 21 and the hollow ring 31 is configured as an arc concave surface 310, so that the outer circumference of the hollow ring 31 can match the arc concave surface 310, which can play a guiding role.

[0069] In addition, in one embodiment, refer to the attached specification Figure 3 There are two hollow rings 31, which are extended from the clamping portion 3 and are located on different sides of the rotating column head 21, so that the rotating shaft rotates through one of the hollow rings 31, the rotating column head 21, and the other hollow ring 31 in sequence to rotatably connect the fixing portion 2 and the clamping portion 3.

[0070] It should be noted that connecting hollow rings 31 on both sides of the rotating column head 21 can improve stability to a certain extent. If only the hollow ring 31 is set on one side, and the rotating shaft is offset to the other side in an unexpected situation, the hollow ring 31 on this side will not be able to be rotatably connected to the rotating column head 21 and will fall off the rotating column head 21. If hollow rings 31 are set on both sides, the mechanism can still rely on the rotational connection relationship on one side to enable normal operation.

[0071] In another embodiment, refer to the attached Figure 2 The connecting end of the clamping part 3 and the fixing part 2 are both provided with corresponding receiving end surfaces, so that after the connecting end is rotated by a preset angle, the two receiving end surfaces can fit together, and the clamping part 3 and the fixing part 2 can form a smooth tail section of the clip-on earphone.

[0072] It should be noted that the design of the receiving end surface can be used to limit the rotation of the connection end. When the corresponding receiving end surfaces are attached, the connection end cannot continue to rotate because there is no extra gap, so that the connection end is fixed in this position. In addition, when the clamping part 3 and the fixing part 2 form a smooth ear-clip earphone tail section, it is also very convenient to store, and the earphone wearing form and style can be diversified. In order to distinguish the receiving end surfaces, the receiving end surface on the fixing part 2 is called the first receiving end surface 201, and the receiving end surface on the clamping part 3 is called the second receiving end surface 202.

[0073] Reference Manual Attached Figure 2 When the clamping part 3 is rotated clockwise, the distance between the first receiving end surface 201 and the second receiving end surface 202 will gradually decrease until the two are completely fitted together. At this time, since the contours of the clamping part 3 and the tail section of the fixing part 2 can match, the two can form a continuous and smooth tail section of the clip-on earphone, which makes the overall appearance very high. At this time, the extension directions of the sound outlet part 1 and the clamping part 3 are the same, which is very suitable for users to wear the earphone when they are not exercising or walking. They only need to place the sound outlet part 1 in the concha cavity without clamping and fixing it, so that they can listen to the sound while relaxing their ears.

[0074] In one embodiment, the reference specification Figure 7 When the clamping part 3 moves to the extreme position, a first preset interval D is set between the clamping part 3 and the sound output part 1, and the setting of the first preset interval D matches the distance between the concha cavity and the back of the ear to provide a clamping space.

[0075] The distance between the concha cavity and the back of the ear can be understood as the thickness of the human ear, that is, the thickness when the concha cavity and the back of the ear are pinched by hand. The extreme position is the position where the clamping part 3 is at the smallest distance from the sound-emitting part 1, and can also be understood as the position where the clamping is the tightest. The first preset interval D is the minimum distance. It is easy to understand that when wearing the clip-on earphone, if the first preset interval D does not match the thickness of the human ear, it may cause the clamping part 3 to exert too much pressure on the ear, causing the clip-on earphone to damage the ear, or the pressure may be too small, making the clamping part 3 unable to clamp the ear, causing the clip-on earphone to fall off, resulting in property loss to the user.

[0076] In one embodiment, after investigating the ear contour dimensions of most people, it can be found that the ear thickness of most people generally does not exceed 4 mm, so in this embodiment, the first preset interval D is at most 4 mm.

[0077] In one embodiment, the reference specification Figure 7 , the distance between the two sides of the adaptation cavity is a second preset interval L, and the second preset interval L matches the distance from the antihelix to the helix of the human ear.

[0078] It should be noted that, the end surfaces on both sides of the adaptation cavity can be set as the first limit surface and the second limit surface for the convenience of expression, and the first limit surface and the second limit surface are respectively the end surface of the fixed part 2 close to the sound output part 1 and the end surface of the fixed part 2 close to the clamping part 3. If the first limit surface and the second limit surface are curved surfaces, the second preset interval L can be calculated from the vertex of the curved surface; in actual situations, due to the different shapes of the inner circumference of the fixed part 2, the first limit surface and the second limit surface may also be planes.

[0079] Among them, the distance from one helix to another helix is ​​adapted to the second preset interval L, so that the width of the fixing part 2 is very reasonable, so that when the fixing part 2 wraps the auricle, it will not produce a sense of oppression thereon, making the ear-clip earphone very comfortable and secure when worn.

[0080] In another embodiment, based on the above embodiment, the range of the second preset interval L is between 6-15 mm. This range is also based on a survey of the population, and the distance interval from the antihelix to the auricle of most people is obtained within this range, which can make the earphones suitable for most people.

[0081] In one embodiment, the reference specification Figure 8 According to another aspect of the present invention, the present invention further provides a method for designing a clip-on earphone, comprising the steps of:

[0082] S100, obtaining the contour data of the concha cavity, and designing a sound source according to the contour data of the concha cavity, so that the contour of the sound source corresponds to the contour of the concha cavity.

[0083] The sound outlet portion includes a sound outlet hole facing the ear canal, and the contour of the sound outlet portion matches the contour of the concha cavity, so that the sound outlet portion can be placed more firmly in the concha cavity, ensuring the firmness of wearing.

[0084] S200, a fixing portion is provided at the tail section of the sound-emitting portion, wherein the fixing portion is curved so that the fixing portion and the sound-emitting portion together form an adaptation cavity to adapt to the contour of the ear.

[0085] S300, obtaining the back of the ear contour data, designing a clamping part according to the back of the ear contour data, and movably connecting the clamping part with an end of the fixing part away from the sound-emitting part, so that the clamping part can abut against the back of the ear for clamping and fixing, so that part of the ear can be wrapped by the clamping part and the fixing part.

[0086] It should be noted that it is necessary to obtain the data of the concha cavity contour, the back of the ear contour, etc., and then design the sound-emitting structure based on the corresponding data, so that the ear-clip earphones can be highly adaptable to the human ear, and data can be collected through population surveys, so that the designed ear-clip earphones can conform to the ear contours of a large part of the population, which has good economic benefits.

[0087] In one embodiment, the steps of providing a fixed portion at the end of the sound-emitting portion specifically include:

[0088] S210, obtaining contour data of the antihelix and the helix, and setting the contour of the fixing portion close to the ear according to the contour data of the antihelix and the helix.

[0089] S220, obtaining antihelix-to-helix distance data, and setting the length of the fixing portion according to the antihelix-to-helix distance data, so that the fixing portion can surround a portion of the antihelix and the helix at the same time.

[0090] It should be noted here that when wearing clip-on earphones, the fixing part surrounds part of the antihelix and the auricle, so the design of the fixing part is very important. If the design of the fixing part is not appropriate, it is easy for the earphone to compress the ear, or the earphone is very loose when worn, which affects safety and is not beautiful.

[0091] Among them, the distance data between the antihelix and the auricle matches the ear clamping distance of the fixing part, and the respective contour data of the two are used to design the contour of the fixing part close to the ear side, so that the fixing part can be well adapted to the contour of the human ear.

[0092] In one embodiment, the back of the ear contour includes a back of the ear groove contour and a helix contour, and designing a clamping portion according to the back of the ear contour data specifically includes:

[0093] S310, obtaining dorsal ear groove contour data, and designing the contour of the clamping end of the clamping portion according to the dorsal ear groove contour data, so that the clamping end can resist and fit the dorsal ear groove.

[0094] S320, obtaining the helix contour data, and designing the ear-contacting surface contour of the clamping portion according to the helix contour data, wherein the ear-contacting surface is the surface of the clamping portion close to the helix, so that the contour of the pressing end and the contour of the ear-contacting surface are smoothly transitioned, and the clamping portion forms a continuous arc surface that can fit the contour of the back of the ear.

[0095] Among them, the design of the clamping part is mainly based on the contour of the dorsal ear groove and the helix. Such a design enables the clamping part to fit the contour of the back of the ear very well when clamped, making the wearing process of the clip-on earphones more comfortable.

[0096] Specifically, the clamping end of the clamping part can be understood as the end of the clamping part close to the back of the ear. Since the back ear groove of the human body has a certain curvature, it is easy to crush the back ear groove if the clamping end is directly set to a square or some sharp shapes. However, if it is directly set to a circle, it is also easy to make the clamping not in place. Therefore, designing the contour of the clamping end according to the contour of the back ear groove can avoid the above problems.

[0097] In addition, the ear-contacting surface of the clamping part can be understood as the end surface of the clamping part close to the back of the ear, which will fit against the back of the ear when the clamping part is clamped relative to the back of the ear. Similarly, if a plane is set randomly, it will easily make the user feel uncomfortable when wearing it, so it is also designed according to the contour of the helix.

[0098] In one embodiment, a clamping portion is designed according to the back of ear contour data, further comprising:

[0099] S330, obtaining distance data from the concha cavity to the back of the ear, and setting a minimum distance between the pressing end and the sound output part according to the distance data from the concha cavity to the back of the ear, so that when wearing a clip-on earphone, the minimum distance can match the thickness of the human ear.

[0100] The clamping part is designed to adapt to the thickness of the human ear. When the user wears the clip-on earphones, the clamping end and the sound-emitting part just clamp the ear. If it is clamped too tightly or too loosely, it will lead to a bad user experience. Therefore, these problems can be avoided by designing the minimum spacing to adapt to the thickness of the ear.

[0101] More preferably, the clamping part is arranged on the fixing part through a rotating member. When clamping and fixing, the clamping part is rotated toward the sound output part and wraps around the back of the ear together with the fixing part to complete the fixation. The operation is very simple and very convenient.

[0102] It should also be noted that the above steps S310, S320, and S330 may be performed simultaneously or separately, and the order may also be changed accordingly.

[0103] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
