Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic front side structure diagram of a profile of an ear of a user according to the present application.
As shown in fig. 1, the ear 100 of the user has a certain depth and volume in a three-dimensional space, in addition to the external auditory canal 101 and the concha cavity 102 near the external auditory canal, such as the concha boat 103, the triangular fossa 104, and the otoboat 106, and can be used for the wearing requirement of the headset. In other words, by properly designing the structure of the headset and using the parts of the user's ear 100 other than the external auditory meatus 101, it is possible to achieve wearing of the headset and propagation of mechanical vibration, as well as "liberating" the external auditory meatus 101 of the user, thereby increasing the physical health of the user and reducing the occurrence probability of traffic accidents. Based on this, the present application proposes a new way to provide an earphone, wherein the movement for generating sound is mainly located at the front side of the tragus 109 of the ear 100 (abbreviated as "tragus front side", for example, the area shown in J in fig. 1) in the wearing state, and mainly realizes wearing of the earphone by means of the upper half part of the ear 100 of the user (specifically, the areas where the cymba concha 103, the triangular fossa 104, the antihelix 105, the otoboats 106, the helix 107, and the like are located). Of course, the user may further use the earlobe 108 or the like in order to improve the wearing comfort and reliability of the earphone.
It should be noted that: although the ear piece of the present application mainly releases the external auditory meatus 101 of the user in a wearing state, a part of the structure of the ear piece (for example, a holding portion mentioned later) may be pressed against the tragus 109, or may even partially cover the external auditory meatus 101.
Referring to fig. 2 to 5 together, fig. 2 is a schematic front view, fig. 3 is a schematic left view, fig. 4 is a schematic front side view, and fig. 5 is a schematic rear side view, of the headset of fig. 2. It should be noted that: the X, Y, Z directions of the earphone are illustrated in fig. 2, mainly to illustrate the XY, XZ, YZ planes for the convenience of the following description. Accordingly, all directional indicators in this application (such as up, down, left, right, front, and rear … …) are used primarily to explain the relative positional relationship, movement, etc. of the components in a particular position (as shown in FIG. 2); if the particular gesture changes, the directional indication changes accordingly.
As shown in fig. 2 and 3, the earphone 10 may include a hook 11, a connection part 12, and a holding part 13. In some embodiments, the connecting portion 12 connects the hook portion 11 and the holding portion 13, so that the earphone 10 is in a three-dimensional curved shape when in a non-wearing state (i.e., a natural state). In other words, the hook 11, the connecting portion 12, and the holding portion 13 may not be coplanar in three-dimensional space. In this way, when the earphone 10 is worn, as shown in fig. 4 and 5, the hook portion 11 may be mainly used to be hooked between the back side of the ear of the user and the head, the holding portion 13 may be mainly used to contact the tragus front side of the ear of the user, and the connecting portion 12 extends from the head to the outside of the head in the worn state, and further cooperates with the hook portion 11 so that the holding portion 13 is stably positioned at the tragus front side of the ear in the worn state.
It should be noted that: for users of children, pre-adults, adult women, etc., the ear thickness is often thin (commonly referred to as "thin ear"), especially compared to the thickness of the ear of an adult male, and the connecting portion 12 may be small in size, for example, the connecting portion 12 is an arc transition between the holding portion 13 and the hook portion 11, in order to increase the fitting degree of the earphone 10 to the ear of the user when the earphone is worn. Further, the connecting portion 12 may be regarded as an extension of the hook portion 11, that is, one end of the hook portion 11 connected to the holding portion 13 is bent so that the hook portion 11 can be wound from the rear side to the front side of the ear in the wearing state. Wherein for an ear, a front side of the ear and a back side of the ear may be understood simply as the front and back sides of the ear, wherein the front side (e.g. front side) of the ear may be as shown in fig. 1.
Further, the earphone 10 may further include a movement 14, a main board 15, and a battery 16. The movement 14 is mainly used for converting an electrical signal into corresponding mechanical vibration (i.e., "sound production"), and may be electrically connected to the motherboard 15 and the battery 16 through corresponding conductors; the main board 15 is mainly used for controlling the sound production of the movement 14, and the battery 16 is mainly used for providing electric energy for the sound production of the movement 14. Of course, the earphone 10 described herein may also include microphones such as a microphone and a sound pick-up, and may further include Communication devices such as bluetooth and NFC (Near Field Communication), which are electrically connected to the main board 15 and the battery 16 through corresponding conductors to implement corresponding functions.
It should be noted that: those skilled in the art can flexibly arrange the above functional components, i.e., the battery, the main board, the movement, etc., in the structural components, i.e., the holding portion, the hook portion, the connecting portion, etc., as needed. For example:
in some embodiments, movement 14 and main board 15 may be provided at holding portion 13, and battery 16 may be provided at hook portion 11. Of course, in other embodiments, movement 14 may be provided at holding portion 13, and battery 16 and main board 15 may be provided at hook portion 11.
In some embodiments, battery 16 and main board 15 may be disposed in holder 13, and movement 14 may be disposed in hook 11. Of course, in other embodiments, battery 16 may be disposed in holder 13, and movement 14 and main board 15 may be disposed in hook 11.
In other embodiments, when one of the movement 14 and the battery 16 is provided in the hook 11 at the same time as the main plate 15, they may be provided at intervals along the length of the hook 11.
As an example, the movement 14 may be fixed to the holding portion 13, and the movement 14 can be stably held at the tragus front side of the ear of the user when the headphone 10 is in the wearing state. Further, when the earphone 10 is worn, since the holding portion 13 is mainly located at the front of the tragus of the user's ear, as shown in fig. 4, the holding portion 13 may be provided with some function keys (not shown in fig. 2) for facilitating the user's interaction with the earphone 10 in addition to fixing the movement 14. Based on this, the main board 15 may also be provided at the holding portion 13 to shorten the routing distance between the movement 14 and other components such as function keys and the like and the main board 15. It is worth noting that: since the holding portion 13 can be provided with the movement 14, the main board 15, the function keys, and the like, and is located on the tragus front side of the user's ear when the earphone 10 is in the wearing state, the battery 16 can be provided in the hook portion 11 and is mainly located between the back side of the user's ear and the head when the earphone 10 is in the wearing state, as shown in fig. 5. So configured, not only can the capacity of the battery 16 be increased to improve the cruising ability of the earphone 10; the weight of the headset 10 may also be balanced to improve the stability and comfort of the headset 10 during wear.
Further, the inventors of the present application found in long-term studies that: the weight ratio of the total weight of the holding portion 13 to the total weight of the portion of the hook portion 11 corresponding to the battery 16 (hereinafter, referred to as a battery portion) may be within 4:1, preferably within 3:1, and more preferably within 2.5: 1. With reference to fig. 2 and 3, in some embodiments, the total weight of the holding portion 13 is the self weight of the holding portion 13 and the weight of the components such as the movement 14 and the main plate 15; the total weight of the battery part is the weight of the battery part and the weight of the structural members such as the battery 16. Of course, those skilled in the art can easily understand that the structural members in the holding portion 13 and the structural members in the battery portion may be changed according to design requirements, and the adjustment of the structural members at different positions is included in the technical solution of the present application, and has no influence on the weight ratio, and will not be described herein again. At this time, the weight of the earphone 10 can be distributed relatively evenly at both ends, and the ear of the user can also be used as a fulcrum to support the earphone 10 when the earphone 10 is in the wearing state, so that the earphone 10 can not slide down at least in the non-moving state when the earphone 10 is in the wearing state. Of course, it follows that the user's ear can bear a large portion of the weight of the headset 10, which can be prone to discomfort in long-wear scenarios. For this reason, the hook portion 11, the connecting portion 12, the holding portion 13, etc. can be made of a material with a soft texture (e.g., polycarbonate, polyamide, abs, silicone, etc.) so as to improve the wearing comfort of the earphone 10. Further, in order to improve the structural strength of the earphone 10, an elastic wire such as spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, aluminum alloy, copper alloy, or the like may be provided in the hook portion 11, the connecting portion 12, the holding portion 13, or the like.
It should be noted that: in order to achieve the comfort and stability of the earphone 10, the following improvements can be made:
1) the connection part 12 and the battery part may be made of hard materials, and the middle part between the connection part and the battery part may be made of soft materials; or the middle part adopts a structure form of 'soft packing hard', for example, when a user wears the earphone 10, the area of the hook-shaped part 11 contacted with the user is selected from the material with soft texture, the other area is selected from the material with hard texture, and different materials are molded by adopting processes of double-shot molding, hand feeling paint spraying and the like. Wherein the hard materials may include, but are not limited to, Polycarbonate (PC), Polyamide (PA), Acrylonitrile Butadiene Styrene (ABS), Polystyrene (PS), High Impact Polystyrene (HIPS), Polypropylene (PP), Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), polyurethanes (PU), Polyethylene (PE), Phenol Formaldehyde resins (PF), polyethersulfone resins (Poly (ester sulfonic acids)), PEs, Polyvinylidene dichloride (PVDC), Polymethyl Methacrylate (PMMA), polyether ether ketone (PEEK), or a mixture of at least two thereof, or a mixture of the same and a reinforcing agent such as glass fiber or carbon fiber. Further, the hand feeling paint can be specifically rubber hand feeling paint, elastic hand feeling paint, plastic elastic paint and the like.
2) Since the headset 10 is worn by the user, a part of the area of the headset 10 is always in contact with the skin of the user (hereinafter: skin contact area); the material of the skin contact area generally affects the comfort of the user when wearing the headset 10 for extended periods of time. Therefore, the skin contact area can be made of the soft material, other areas are made of the hard material, and different materials are molded by adopting processes of double-shot molding, hand feeling paint spraying and the like.
Wherein, the Shore hardness of the softer material can be 45-85A and 30-60D. Of course, the elastic wire may be coated with the soft material or the hard material.
3) The holding portion 13 may be provided with a face-fitting structure, that is, the face-fitting structure may be in direct contact with the skin of the user instead of the holding portion 13 when the user wears the earphone 10. Wherein the face structure and the holding portion 13 can be detachably connected. Further, the face structure may preferably be made of a material with good skin-friendly property and air permeability, so as to reduce the stimulation of the face structure to the skin of the user, and further increase the comfort level of the earphone 10 in wearing.
In some embodiments, the face-attaching structure may be a self-adhesive sheet, a double-sided adhesive tape, or other structures with certain adhesiveness, one surface of which may be adhered to the holding portion 13, and the other surface of which may be used to achieve adhesive fixation between the holding portion 13 and a human face, thereby increasing the wearing stability of the earphone 10. Furthermore, some granular materials can be mixed into the sticky sheet, the double faced adhesive tape and other structures, so that the surface of the face pasting structure is in a high-low fluctuation state, the contact area between the face pasting structure and the skin of a user can be increased, the air permeability of the face pasting structure can also be increased, and the stimulation of the face pasting structure to the skin of the user can also be reduced. By the arrangement, the face-attaching structure can realize the original viscous fixing effect and can effectively prevent the discomfort of a sensitive person caused by skin compression; when the user takes off the earphone 10, the tearing, pain and roughness caused by the increase of the viscosity of the face pasting structure can be effectively avoided. Certainly, the front and back surfaces of the face pasting structure can be provided with release paper and the like, so that the face pasting structure can be used simply and conveniently by taking off the release paper when a user needs the face pasting structure.
In other embodiments, the face-contacting structure may be a hydrogel, hydrocolloid, or other dressing with certain water absorption, one side of which may be glued to the holding portion 13, and the other side of which may be used to achieve adhesive fixation between the holding portion 13 and the human face, thereby increasing the wearing stability of the earphone 10. The face-pasting structure can provide better skin contact feeling for a user, sweat and the like generated between the holding part 13 and the skin of the user due to long-time wearing can be absorbed, and discomfort of a sensitive person due to skin pressure can be effectively prevented.
In other configurations, the facing structure may be a slip-resistant sleeve that fits over the retaining portion 13. The damping coefficient of the anti-slip cover is greater than that of the holding part 13, so that the friction force formed when the holding part 13 is in contact with the skin of the user is increased, and the wearing stability of the earphone 10 is further increased. Further, the surface of the anti-slip cover contacting with the skin of the user may be provided with a texture structure as shown in fig. 14 (a), or may be provided with a dot-shaped protrusion as shown in fig. 14 (b), or may be provided with a dot-shaped recess to increase the air permeability of the anti-slip cover.
In still other configurations, the surface of the holding portion 13 that contacts the skin of the user may have a textured structure as shown in fig. 14 (a), a dot-like projection as shown in fig. 14 (b), or a dot-like depression to achieve both of the friction and the air permeability between the holding portion 13 and the skin of the user.
With reference to fig. 2 to 5, the earphone 10 may further include an auxiliary portion 17 connected to the holding portion 13. Wherein, under the wearing state, the auxiliary part 17 is used for propping against the inside of the ear boat of the ear. In this way, the auxiliary portion 17 can prevent the holding portion 13 from moving toward the ear by being supported in the ear boat of the ear, and can also hold the ear of the user in "tandem" in cooperation with the hook portion 11, thereby improving the stability of the headset 10 in terms of wearing. Further, in the wearing state, and viewed along the coronal axis of the human body, the auxiliary portion 17 and the hook portion 11 extend at least partially in the same direction, so that the auxiliary portion 17 better adapts to the contour of the ear and is thus better supported on the ear. Of course, in some other embodiments, the auxiliary portion 17 may also be used to abut against other positions on the front side of the ear except for the otoboat, for example, the upper half of the front side of the ear, specifically, the cymba concha, fossa trigonalis, antihelix, otoboat, and helix. In this way, the stability of the headset 10 in terms of wearing can likewise be improved.
It should be noted that: in the fields of medicine, anatomy, and the like, three basic sections of a human body can be defined, namely, a Sagittal Plane (Sagittal Plane), a Coronal Plane (Coronal Plane), and a Horizontal Plane (Horizontal Plane), and three basic axes, namely, a Sagittal Axis (Sagittal Axis), a Coronal Axis (Coronal Axis), and a Vertical Axis (Vertical Axis). Wherein, the sagittal plane is a section perpendicular to the ground along the front and back direction of the body, which divides the human body into a left part and a right part; the coronal plane is a section perpendicular to the ground along the left and right directions of the body, and divides the human body into a front part and a rear part; the horizontal plane is a section parallel to the ground along the up-down direction of the body, and divides the body into an upper part and a lower part. Accordingly, the sagittal axis means an axis passing perpendicularly through the coronal plane in the anteroposterior direction of the body, the coronal axis means an axis passing perpendicularly through the sagittal plane in the left-right direction of the body, and the vertical axis means an axis passing perpendicularly through the horizontal plane in the up-down direction of the body.
As an example, the auxiliary portion 17 may include a supporting section 171 and an abutting section 172 connected to the supporting section 171 in a bending manner. The supporting section 171 is connected to the holding portion 13, and the abutting section 172 is used for abutting against the inside of the ear boat of the ear. Based on this, parameters such as the length of the supporting section 171 and the included angle between the connecting end thereof and the connecting end of the holding portion 13 can be reasonably designed according to factors such as the specific position where the supporting section 171 is connected with the holding portion 13, the distance between the abutting section 172 and the holding portion 13, and the specific position where the abutting section 172 abuts against the inside of the ear boat of the ear, and parameters such as the size and the shape of the abutting section 172 can be designed into a profile structure according to the ear boat of the ear and human tissues around the ear boat.
Further, the support section 171 may be made of the hard material to ensure the structural strength of the support against the top section 172, and the area contacting the skin of the user may be provided with the touch paint. Accordingly, the abutting section 172 may be made of the above-mentioned softer material to avoid the auxiliary portion 17 from stabbing the user. Of course, in order to ensure the structural strength of the auxiliary portion 17 in the overall structure and the connection strength with the holding portion 13, an elastic wire such as spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, aluminum alloy, copper alloy, or the like may also be provided in the auxiliary portion 17. Those skilled in the art will readily appreciate that in some embodiments, the skin-contacting surface of the supporting section 171 and the abutting section 172 may be formed by an adhesive structure or a water-absorbent dressing in the face-contacting structure of the previous embodiments, and other skin-contacting portions of the earphone 10 may be similarly designed, and will not be described herein.
Further, the supporting section 171 may have a wavy structure, a spiral structure, etc. along the length direction of the auxiliary portion 17, so that the supporting section 171 has a certain elasticity, so that the propping section 172 better props against the inside of the ear boat of the ear.
Further, in some embodiments, the retaining portion 13 may have a major axis direction (e.g., the direction indicated by arrow Z in fig. 2) and a minor axis direction (e.g., the direction indicated by arrow Y in fig. 2). The dimension of the holding portion 13 in the major axis direction may be greater than or equal to the dimension thereof in the minor axis direction. At this time, one end of the holding part 13 in the long axis direction may be connected to the hook part 11 through the connection part 12 so that the earphone 10 is hooked on the ear of the user; the auxiliary portion 17 is connected to the holding portion 13 on a side close to the hook portion 11, so that the auxiliary portion 17 extends into and abuts against the ear boat of the ear in the wearing state.
With reference to fig. 2 to 5, the respective outer surfaces of the holding portion 13 are now defined as follows: 1) the side of the holding portion 13 that contacts the front side of the tragus of the ear in the worn state is defined as an inner surface, and the side of the holding portion 13 that opposes the inner surface is defined as an outer surface; 2) the side of the holding portion 13 connected to the hook portion 11 is defined as an upper surface, and the side of the holding portion 13 opposite to the upper surface in the long axis direction is defined as a lower surface; 3) a side of the holding portion 13 near the ear in the worn state is defined as a rear surface, and a side of the holding portion 13 opposite to the rear surface in the short axis direction is defined as a front surface. In short, the outer surface and the inner surface may be disposed opposite to each other in the X direction, the lower surface and the upper surface may be disposed opposite to each other in the Z direction, and the front surface and the rear surface may be disposed opposite to each other in the Y direction. Wherein the edges between the outer surfaces may be provided with chamfers and/or fillets.
Obviously, when the earphone 10 is worn, the upper surface, the rear surface, the lower surface of the holding portion 13 and the junction between two of the upper surface, the rear surface and the lower surface of the holding portion 13 can be closer to the ear boat of the ear in terms of the distance between different positions on the holding portion 13 and the ear boat of the ear, so that the auxiliary portion 17 can be more conveniently inserted into and abutted against the ear boat of the ear. In other words, the auxiliary portion 17 may be provided on any one of the upper surface, the rear surface, and the lower surface of the holding portion 13; alternatively, the auxiliary portion 17 may be provided at the boundary between the upper surface and the rear surface of the holding portion 13; alternatively, the auxiliary portion 17 may be provided at the boundary between the rear surface and the lower surface of the holding portion 13.
It should be noted that: when the dimension of the holding portion 13 in the major axis direction is larger than that in the minor axis direction, the holding portion 13 may have a rectangular parallelepiped structure as shown in fig. 2, and projections of the inner and outer surfaces thereof on the YZ surface are substantially rectangular; the holding portion 13 may have an elliptic cylindrical structure, and projections of inner and outer surfaces thereof on YZ surfaces may have a substantially elliptic shape. When the dimension of the holding part 13 in the major axis direction is equal to the dimension thereof in the minor axis direction, the holding part 13 may have a rectangular parallelepiped structure, the projections of the inner and outer surfaces thereof on the YZ surface being substantially square; or a cylindrical structure, and the projections of the inner surface and the outer surface on the YZ surface are generally circular. Of course, the holding portion 13 may have other types of structures, which are not listed here. Further, when the holding portion 13 has an elliptical cylinder, a cylindrical body, or the like, the upper surface, the lower surface, the rear surface, and the front surface may be collectively defined as a circumferential surface.
For example, referring to fig. 2 and 12, the supporting segment 171 may be disposed at a boundary between the upper surface and the rear surface of the holding portion 13, at a rear surface of the holding portion 13, or at a boundary between the rear surface and the lower surface of the holding portion 13. At this time, an angle formed between the extending direction of the supporting section 171 and the long axis direction may be within a closed range [0 °, 30 ° ] so that the propping section 172 protrudes into and props against the otoboat of the ear. Among them, since the dimension of the holding part 13 in the Z direction may be 22 to 28mm and the dimension in the X direction may be 8 to 15mm, the distance between the connecting point of the support section 171 and the holding part 13 and the inner surface of the holding part 13 may be 0 to 9mm, and the distance between the connecting point and the upper surface of the holding part 13 may be 0 to 20 mm.
Further, an angle formed between a projection of the support section 171 on a reference plane (e.g., XY plane) perpendicular to the long axis direction and the short axis direction may be within a range of a closed interval [0 °, 60 ° ] so that the auxiliary portion 17 can also grip the ear of the user together with the hook portion 11 in a wearing state, thereby improving the stability of the headset 10 in wearing.
Referring to fig. 26, the holding portion 13 may be configured as a housing with an opening, and the connecting portion 12 may be fastened to the opening of the holding portion 13 to form a cavity structure. Illustratively, the outer surface side of the holding portion 13 is provided to be open and connected to the connecting portion 12 so that the connecting portion 12 serves as the outer surface of the holding portion 13 in a wearing state. At this time, since the holding portion 13 has a certain depth in the X direction, the connecting portion 12 may be provided to be curved in a direction approaching the inner surface of the holding portion 13, that is, the connecting portion 12 gradually approaches the head of the user in a wearing state to be connected with the hook portion 11. With such an arrangement, the connecting portion 12 can effectively improve the influence of the thickness difference of the ears of different users on the wearing stability.
Further, the auxiliary portion 17 may be connected with the connection portion 12. Illustratively, the support section 171 is connected to an end of the connecting portion 12 near the hook portion 11 so as to facilitate better abutment of the abutment section 172 against the inside of the ear canal of the ear.
Referring to fig. 6, fig. 6 is a mechanical model diagram of the earphone in fig. 2 in a wearing state. It should be noted that: the YZ plane in FIG. 6 may be considered to be the plane of the user's head; the ABC section in fig. 6 can be regarded as the hook, the CD section in fig. 6 as the connection section, the EF section in fig. 6 as the holding section, and the GHI section in fig. 6 as the auxiliary section. Further, point C in fig. 6 may correspond to the area where the upper near head end of the ear in fig. 1 is located (the area indicated by dashed box C in fig. 1).
As shown in fig. 4 to 6, when the earphone 10 is worn, the ABC section is located mainly at the rear side of the user's ear, the EF section is located mainly at the front side of the tragus of the user's ear, and the CD section is mainly adapted to the thickness of the user's ear; while the DE section can be regarded as a transition between the attachment portion and the retaining portion, also mainly at the front side of the user's ear. At this time, the BC segment, the CD segment and the EF segment can form a structure similar to a "hook" so that the earphone 10 can be hooked on the ear of the user, thereby forming a basic wearing situation. Further, the GHI section is located primarily in front of the user's ear and may extend into the ear boat of the ear. The following is an exemplary description of the force applied to the headset 10 during wearing and its stability, etc.:
as shown in fig. 6, the hook 11 is bent toward the head of the user in a direction from a first connection point C between the hook 11 and the connection 12 to a free end (e.g., an end at which point a in fig. 6 is located) of the hook 11, and forms a first contact point B and a second contact point a with the head. The first contact point B is located between the second contact point A and the first connection point C. It should be noted that: the first contact point B and the second contact point a are defined points in a mechanical model, and when the earphone is actually worn, due to differences in physiological structures of the head, the ear and the like of different users, the earphone 10 is actually worn, and the position of the earphone 10, which is in contact with the head when the earphone is actually worn, may correspond to the free end of the hook-shaped portion 11, or may be any point between the free end and the first contact point B; certainly, the AB segment may be partially or entirely abutted against the head of the user, and the mechanical model and the stabilization principle in actual wearing of the AB segment are the same as those in the above technical solutions, so that those skilled in the art can easily know and adjust the contents of the AB segment without creative work based on the technical solutions of the present application, and details are not described here. It is so arranged that the hook 11 forms a lever structure with the first contact point B as a fulcrum. At this time, the free end of the hook portion 11 is pressed against the head of the user, and the head of the user provides a force directed to the outside of the head at the second contact point a, which is converted into a force directed to the head at the first contact point C by the lever structure, thereby providing the holding portion 13 with a pressing force against the tragus front side of the ear via the connecting portion 12.
It should be noted that: in order to enable the free end of the hook 11 to be pressed against the head of the user when the headset 10 is in the wearing state and to enable the head of the user to provide a force directed outward of the head at the second contact point a, at least the following conditions need to be satisfied: the free end of the hook-like portion 11 forms an angle with the YZ-plane when the earphone 10 is in a non-wearing state that is larger than the angle formed by the free end of the hook-like portion 11 with the YZ-plane when the earphone 10 is in a wearing state. Wherein the larger the included angle formed between the free end of the hook-shaped part 11 and the YZ plane when the earphone 10 is in the non-wearing state, the better the free end of the hook-shaped part 11 can be pressed against the head of the user when the earphone 10 is in the wearing state, and the larger the force directed to the outside of the head can be provided by the head of the user at the second contact point a.
Further, based on the above analysis of the mechanical model, when the hook 11 is hooked between the back side of the ear of the user and the head, the hook 11 contacts the head of the user and/or the back side of the ear, and may also receive another reaction force, and the reaction force may cause the holding part 13 to move toward the ear after being converted by the connecting part 12, and may cause the holding part 13 to rotate about the connecting part 12 and toward the ear. In this regard, the auxiliary portion 17 is bent toward the ear of the user in a direction from a connection point G between the auxiliary portion 17 and the holding portion 13 to a free end (e.g., an end at which point I in fig. 6) of the auxiliary portion 17, and forms a contact point H and a contact point I with the ear. Wherein the contact point H is located between the contact point I and the connection point G. The arrangement is such that the auxiliary portion 17 forms a support structure with the connection point G as a fulcrum. At this time, the free end of the auxiliary portion 17 extends into and abuts against the ear boat of the ear, and the ear of the user can provide a reaction force directed to the holding portion 13 at the contact point H, and the reaction force causes the holding portion 13 to form a moment to counteract the reaction of the back side of the head and/or the ear of the user to the hook portion 11, so that the holding portion 13 cannot move in the direction close to the ear.
It is worth noting that: when the free end of the hook portion 11 is pressed against the head of the user, besides enabling the head of the user to provide a force pointing to the outside of the head at the second contact point a, at least the segment BC of the hook portion 11 can form another pressing force on the rear side of the ear, and can cooperate with the pressing force formed by the auxiliary portion 17 on the front side of the ear to form a "front-back pinching" pressing effect on the ear of the user, thereby improving the wearing stability of the earphone 10.
Further, the battery 16 may be disposed mainly at the AB segment of the hook portion 11 (i.e. the battery portion), so as to overcome the dead weight of the holding portion 13 and the inner movement 14 and the main board 15 therein, and further improve the wearing stability of the earphone 10. Of course, the surface of the hook-shaped portion 11 contacting the ear and head of the user may be a frosted surface, a textured surface, or the like, so as to increase the friction between the hook-shaped portion 11 and the ear and head of the user, so as to overcome the self-weight of the holding portion 13 and the inner movement 14 and the main board 15 therein, and further improve the wearing stability of the earphone 10. Further, the free end of the hook-shaped portion 11 (especially, the area of the point a) can be deformed, so that when the earphone 10 is in a wearing state, the free end of the hook-shaped portion 11 is pressed against the head of the user and deformed, and the contact area between the free end of the hook-shaped portion 11 and the head of the user is increased, thereby improving the wearing comfort and stability of the earphone 10. For example: the hook 11 is formed by two-shot molding, and the elastic modulus of the free end (especially the area where the point A is located) is smaller than that of the other areas, so that the deformation capacity of the free end is increased. For another example: the free end of the hook 11 is provided with a hole 111, which is a hollow structure to increase the deformation capability of the free end. The holes 111 may be through holes and/or blind holes, and may be one or more, and the axial direction thereof may be perpendicular to the contact surface between the free end of the hook 11 and the head of the user.
It should be noted that: in order to achieve the comfort and stability of the earphone 10, the following improvements can be made:
1) the skin contact area of the battery part is formed with a texture structure, which, in fig. 14 (a), may be a plurality of strip-shaped protrusions 112 spaced apart along the length direction of the hook part 11; referring to fig. 14 (b), the texture structure may be a plurality of dot-shaped protrusions 113 spaced apart from each other along the length of the hook 11; of course, the texture structure may also be in a grid shape.
2) Referring to fig. 14 (c), the skin contact area of the battery part may be further provided with a semi-spindle-shaped protrusion 114 extending in the longitudinal direction of the hook part 11. Here, with reference to the free end of the hook 11, the half-spindle-shaped protrusion 114 has portions which are gradually increased and then gradually decreased in height with respect to the protrusion of the hook 11 in a direction (a direction indicated by an arrow in fig. 14) near the free end of the hook 11. The arrangement is such that as little resistance as possible is generated between the semi-fusiform protrusion 114 and the user's skin during wearing of the headset 10 by the user; after the user wears the earphone 10, the semi-spindle-shaped protrusion 114 and the skin of the user can generate a large resistance as much as possible to prevent the earphone 10 from falling off.
3) When the skin contact area of the battery part is provided as a frosted surface, a material having a good skin-friendly property may be preferable.
Wherein, the materials with soft texture, large damping coefficient and certain skin affinity can be selected for the various bulges. Further, with the various embodiments described above, the friction coefficient of the skin contact area of the battery part may reach 0.1 to 1.0.
Illustratively, the linear distance between the projection of point C on the YZ plane and the projection of section EF on the YZ plane (which may also be considered as the length of section DE) may be 10-17mm, preferably 12-16mm, and more preferably 13-15 mm. The projection of the BC-segment onto the XY-plane may be at an angle of 0-25 °, preferably 0-20 °, more preferably 2-20 ° to the Y-direction. Further, the angle between the AB segment and the normal on the XY plane passing through point B may be 0-25 °, preferably 0-20 °, and more preferably 2-20 °. Further, the straight-line distance between the projection of the point C on the XY plane and the projection of the segment EF on the XY plane (which can also be regarded as the length of the CD segment) may be 0-5mm, preferably 2-4mm, and more preferably 2.8 mm.
Further, the projection of the GH segment on the YZ plane may be at an angle of 0-60 °, preferably 0-30 °, more preferably 0-10 ° to the Z direction. The projection of the GH segment onto the XY plane may be at an angle of-30 ° -60 °, preferably 0-60 °, more preferably 0-30 °, to the Y direction.
Based on the above detailed description, the present application, on the one hand, provides a reasonable and balanced distribution of the weight of the headset 10, so that the ear of the user can serve as a fulcrum to support the headset 10 when the headset 10 is worn; on the other hand, a connecting part 12 is arranged between the hook-shaped part 11 and the holding part 13 of the earphone 10, so that the connecting part 12 is matched with the hook-shaped part 11 when the earphone 10 is in a wearing state to provide pressing force on the front side of the tragus of the ear for the holding part 13, and further, the earphone 10 can be firmly attached to the ear of a user when in the wearing state. With this arrangement, the stability of the headphone 10 in terms of wearing and the reliability of the headphone 10 in terms of sound emission can be improved.
Referring to fig. 7 to 11 together, fig. 7 is a schematic front view structure diagram of another embodiment of the headset provided by the present application, fig. 8 is a schematic left view structure diagram of the headset in fig. 7, fig. 9 is a schematic front side view angle diagram of the headset in fig. 7 in a wearing state, fig. 10 is a schematic rear side view angle diagram of the headset in fig. 7 in the wearing state, and fig. 11 is a schematic mechanical model diagram of the headset in fig. 7 in the wearing state. It should be noted that: the YZ plane in FIG. 11 may be considered as the plane of the user's head; the ABC section in fig. 11 can be regarded as the hook, the CD section in fig. 11 as the connection section, the EF section in fig. 11 as the holding section, and the GHI section in fig. 11 as the auxiliary section. Further, point C in FIG. 11 may correspond to the area of the ear near the upper head end in FIG. 1 (shown as dashed box C in FIG. 1).
The main differences from the above described embodiment are: in the present embodiment, as shown in fig. 7 and 8, the hook portion 11 is integrally closer to the holding portion 13, so that when the earphone 10 is in a wearing state, as shown in fig. 9 and 10, the free end of the hook portion 11, which is away from the connecting portion 12, acts on the rear side of the ear of the user, rather than pressing against the head of the user.
As shown in fig. 11, in a direction from a first connection point C between the hook portion 11 and the connection portion 12 to a free end (e.g., an end at a point a in fig. 11) of the hook portion 11, the hook portion 11 is bent toward a rear side of the ear and forms a first contact point B with the rear side of the ear, and the holding portion 13 forms a second contact point F with a front side of the tragus of the ear. Here, with the earphone 10, the distance between the first contact point B and the second contact point F in the extending direction of the connecting portion 12 in the natural state (i.e., the unworn state) is smaller than the distance between the first contact point B and the second contact point F in the extending direction of the connecting portion 12 in the worn state, thereby providing the holding portion 13 with a pressing force against the tragus front side of the ear. In other words, the distance between the first contact point B and the second contact point F in the extension direction of the connecting portion 12 in the natural state of the headphone 10 is smaller than the thickness of the user's ear, so that the headphone 10 can be clipped to the user's ear like a "clip" in the wearing state.
Further, a first connection line BC is provided between the first contact point B and the first connection point C, and a second connection line EF is provided between the second contact point F and a second connection point E of the holding portion 13 and the connection portion 12.
Further, the hook 11 may also extend in a direction away from the connecting portion 12, that is, the entire length of the hook 11 is extended, so that when the earphone 10 is in a wearing state, the hook 11 may also form a third contact point a with the rear side of the ear, and the first contact point B is located between the first contact point C and the third contact point a and close to the first contact point C. Here, with the earphone 10, the distance between the projections of the first contact point B and the third contact point a on a reference plane (for example, YZ plane in fig. 11) perpendicular to the extending direction of the connecting portion 12 in the natural state is smaller than the distance between the projections of the first contact point B and the third contact point a on a reference plane (for example, YZ plane in fig. 11) perpendicular to the extending direction of the connecting portion 12 in the worn state. With this arrangement, not only can the free end of the hook portion 11 be pressed against the rear side of the ear of the user, but also the ABC segment can be C-shaped, wherein the third contact point a can be located in the area of the ear close to the earlobe, so that the hook portion 11 can clamp the ear of the user in the vertical direction (as indicated by arrow Z in fig. 11) to overcome the self weight of the holding portion 13. In addition, after the whole length of the hook part 11 is extended, not only the ear of the user can be clamped in the vertical direction, but also the contact area between the hook part 11 and the ear of the user can be increased, that is, the friction force between the hook part 11 and the ear of the user can be increased, thereby improving the stability of the earphone 10 in wearing.
It should be noted that: in order to achieve the comfort and stability of the earphone 10, the following improvements can be made:
1) since the hook 11 needs to match the ears of different users, and the ears of different users are different in size and shape, the free end (for example, the battery part) of the hook 11 is prone to be in a suspended state when the user with a small ear wears the earphone 10, that is, the hook 11 and the ears of the user only form the first contact point B. Therefore, referring to fig. 7 and 8, the hook portion 11 has a structure in which the battery portion has a larger outer diameter than the other middle portion, i.e., has a step, and is gradually necked. This is provided, in conjunction with fig. 9 and 10, so that when the user wears the headset 10, the hook 11 not only forms the first contact point B with the user's ear, but also forms the third contact point a with the user's ear at the free end, i.e. the battery part forms the third contact point a with the user's ear under any circumstances. Obviously, the progressive constriction may be distributed in plurality at intervals along the length of the hook 11 in order to fit a wider user population.
2) Similarly, the ratio of the length of the battery portion to the outer diameter of the battery portion also affects the fit of the hook portion 11 to the ear of the user. Based on this, the inventors of the present application found in long-term studies that: with reference to fig. 7 and 8, the ratio of the length of the battery part to the outer diameter may be within 6:1, and preferably within 4: 1. At this time, the hook-shaped portion 11 not only forms the first contact point B with the ear of the user, but also forms the third contact point a with the ear of the user at the free end, that is, the battery portion can be well attached to the ear of the user.
Referring to fig. 13, fig. 13 is a schematic front view of a headset according to another embodiment of the present application.
The main differences from any of the above embodiments are: in this embodiment, the holding portion 13 has a multi-stage structure so as to adjust the relative position of the movement 14 on the whole structure of the earphone 10. The arrangement is such that when the earphone 10 is worn, the external auditory canal of the ear is not shielded, and the movement 14 is close to the external auditory canal as much as possible.
As an example, as shown in fig. 13, the holding portion 13 may include a first holding section 131, a second holding section 132, and a third holding section 133 that are connected end to end in this order. One end of the first holding section 131, which is away from the second holding section 132, is connected to the connecting portion 12, and the third holding section 133 is mainly used for arranging structural members such as the movement 14 and the main board 15. Further, the second retaining section 132 is folded back relative to the first retaining section 131 and has a spacing therebetween, i.e., the two are in a U-shaped configuration. So configured, the first and second holding sections 131 and 132 can also be pressed against the front side of the ear (such as the area where the antihelix is located) to grip the user's ear together with the hook 11.
Based on the above description, different users may have great differences in age, sex, gene-controlled trait expression, etc., and thus the ears and heads of different users may have different sizes and shapes. Then, on the basis of any of the above embodiments, the related structure of the earphone 10 can be further modified as follows, so as to meet the wearing requirements of a wider user group, and enable different users to have good comfort and stability when wearing the earphone 10.
Referring to fig. 15, fig. 15 is a schematic structural diagram of another embodiment of the earphone provided by the present application.
The main differences from any of the above embodiments are: in this embodiment, in conjunction with fig. 15, the free end of the hook 11 may also be provided with a resilient structural member 18. The elastic structure member 18 may be made of the above material with soft texture, and has a certain structural strength, and the comfort of the user wearing the earphone 10 can be considered. Further, the elastic structure 18 may be tubular and may be detachably fitted over the free end of the hook 11. In this case, the elastic structure 18 can be used as an accessory of the earphone 10, so that the user can conveniently mount or dismount the earphone according to actual use requirements. Wherein the portion of the resilient structure 18 that contacts the user may be provided with the texture described above, the frosted surface described above.
As an example, the elastic structure 18 may include a first tubular portion 181 and a second tubular portion 182 that are integrally connected. The first tubular portion 181 and the second tubular portion 182 are bent, and the specific bending angle can be designed reasonably according to actual use requirements. Of course, the elastic structure member 18 may have a certain memory property at least at the bending position thereof, so that the user can flexibly adjust the bending angle by bending, folding, and the like. This is provided so that the resilient structure 18 can hook over the auricular root socket of the ear from the rear side of the user's ear when the user is wearing the headset 10 to avoid the headset 10 falling out.
Further, the first tubular portion 181 and the second tubular portion 182 may be hollow tubular, and may or may not be in communication with each other; and all can be sleeved at the free end of the hook-shaped part 11. In the present embodiment, the first tubular portion 181 and the second tubular portion 182 are not connected to each other for exemplary illustration, so as to improve the structural strength of the elastic structural member 18 at the bending position thereof. The length (L1) of the first tubular part 181 and the length (L2) of the second tubular part 182 may not be equal, so that a user can select one of the first tubular part 181 and the second tubular part 182 to be sleeved on the free end of the hook part 11 according to actual use requirements, and further adjust the actual total length of the hook part 11 and the elastic structural member 18. In this case, the elastic member 18 may partially or entirely cover the battery part. Referring to fig. 15, the present embodiment is exemplarily described by taking an example that the elastic structural member 18 partially covers the battery part, for example, the elastic structural member 18 covers half of the battery part.
The inventors of the present application found in long-term studies that: referring to fig. 15, when the difference in length between the length (L1) of the first tubular part 181 and the length (L2) of the second tubular part 182 is within the range of 2.0-8.0mm, the elastic structure 18 can better catch the auricular root fossa on the back side of the ear when the headset 10 is worn by different users. Preferably, the difference in length is in the range of 3.5-7.0 mm.
Based on the above detailed description, the free end of the hook 11 is sleeved with the elastic structure 18 to increase the outer diameter of the battery, i.e. to change the actual outer diameter of the free end of the hook 11, so as to better adapt to the external ear contour angle of different user groups, especially to the "hurricane ear", and further improve the rotation and eversion problems of the earphone 10. Based on this, by designing the wall thickness of the first tubular portion 181 and/or the second tubular portion 182, a step difference can be formed between the elastic structural member 18 and the battery portion, so as to achieve a technical effect similar to the progressive necking.
Referring to fig. 16 and 17 together, fig. 16 is a perspective structural view of the hook portion in fig. 8, and fig. 17 is a cross-sectional structural view of the elastic wire in fig. 16 on a reference plane perpendicular to an extending direction of the hook portion. It should be noted that: the elastic wire shown in fig. 16 is generally embedded in the hook portion and the like and is not visible, but is illustrated to be externally visible for convenience of description, for example, a part of the material covering the elastic wire is removed.
Based on the above description, the hook 11, the connecting portion 12, the holding portion 13, etc. may be further provided with an elastic wire 115 such as spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, etc. to improve the structural strength of the earphone 10. Generally, the cross-section of the elastic wire 115 may be circular.
Referring to fig. 16 and 17, the elastic wire 115 may have a flat structure, so that the elastic wire 115 has different deformation capacities in various directions. The cross section of the elastic wire 115 may be a rounded rectangle as shown in fig. 17 (a), or an ellipse as shown in fig. 17 (b). Illustratively, the ratio between the long side (or major axis, L3) of the resilient wire 115 and its short side (or minor axis, L4) may be in the range of 4:1-6:1, and preferably may be 5: 1. Further, referring to fig. 17 (c), in the case that the cross section of the elastic wire 115 is a rounded rectangle shown in fig. 17 (a), the elastic wire 115 may be formed into an arc shape in the short axis direction by a process such as stamping, pre-bending, and the like, so that the elastic wire 115 can store a certain elastic potential energy. For example: the elastic metal wire 115 is in a curled state in an original state, and is made to be arc-shaped in the short axis direction by a pressing process after being straightened, so that the elastic metal wire 115 can store certain internal stress to maintain a straight state to be a memory metal wire; when a small external force is applied, the curling state is recovered, and the hook-shaped part 11 is attached and wrapped on the human ear. Illustratively, the ratio between the arc height (L5) of the elastic wire 115 and the long side (L3) thereof may be in the range of 0.1-0.4.
In this way, under the action of the elastic wire 115 with the flat sheet structure, not only the hook-shaped portion 11 has stronger rigidity in the X direction, but also the hook-shaped portion 11 and the holding portion 13 cooperate to form effective elastic clamping for the ear 100 of the user; the hook 11 is also made to have strong elasticity due to bending along the length direction thereof, so that the hook 11 itself can be effectively pressed against the ear or head of the user.
Referring to fig. 18 and 19 together, fig. 18 is a schematic structural view of an embodiment of a rotating shaft assembly according to the present application, and fig. 19 is a schematic structural view of the rotating shaft assembly in fig. 18 before and after assembly. It should be noted that: it should be noted that: the shaft assembly shown in fig. 18 is typically embedded in the joint and is not visible, but for ease of description it is shown externally, e.g. by removing some of the material covering the shaft assembly.
Different users may have great differences in age, sex, gene-controlled trait expression, etc., resulting in different users' ears and heads possibly having different sizes and shapes. For this purpose, the hook portion 11 is rotatable relative to the connecting portion 12, or the holding portion 13 is rotatable relative to the connecting portion 12, or one portion of the connecting portion 12 is rotatable relative to another portion, so that the relative position relationship of the hook portion 11, the connecting portion 12 and the holding portion 13 in the three-dimensional space can be adjusted, so that the earphone 10 can be adapted to different users, that is, the application range of the earphone 10 to the user in terms of wearing can be increased. For example: the connecting part 12 is made of deformable materials such as soft steel wires, and a user can adjust the relative positions of the hook-shaped part 11, the connecting part 12 and the holding part 13 in a three-dimensional space by bending the connecting part 12 to enable one part to rotate relative to the other part, so that the wearing requirements of the user are met. For another example: the connecting part 12 is provided with a rotating shaft mechanism 121, and a user can also adjust the relative positions of the hook-shaped part 11, the connecting part 12 and the holding part 13 in a three-dimensional space through the rotating shaft mechanism 121, so as to meet the wearing requirements of the user. The detailed structure of the rotating shaft mechanism 121 is within the understanding of those skilled in the art, and will not be described in detail here. Further, if the hook-shaped portion 11 is movably connected to the connecting portion 12 through the rotating shaft mechanism 121, the hook-shaped portion 11 can rotate relative to the connecting portion 12; if the holding part 13 is movably connected with the connecting part 12 through the rotating shaft mechanism 121, the holding part 13 can rotate relative to the connecting part 12; if one part of the connecting part 12 is movably connected with the other part through the rotating shaft mechanism 121, one part of the connecting part 12 can rotate relative to the other part.
Referring to fig. 18, the shaft mechanism 121 may be a bendable metal leaf spring, one end of which may be connected to the hook 11, and the other end of which may be a part of the connecting portion 12. For example: the metal elastic sheet can be connected with the connecting part 12 into a whole through a metal insert injection molding process and is connected with the hook part 11. With this arrangement, the metal elastic piece deforms under the action of the external force F, so that the hook portion 11 can be switched between the first use state (shown by a solid line in fig. 18, for example) and the second use state (shown by a broken line in fig. 18, for example) with respect to the holding portion 13, that is, the hook portion 11 can rotate with respect to the holding portion 13.
As an example, referring to fig. 19, the metal dome may include a first deformation portion 1211, a second deformation portion 1212, and an intermediate connection portion 1213. Before the metal dome is mounted, as shown in fig. 19 (a), the first deformation portion 1211 and the second deformation portion 1212 are respectively connected to two ends of the intermediate connecting portion 1213 in a bending manner. Further, after the metal dome is installed, referring to fig. 19 (b), a free end of the first deformation portion 1211 facing away from the intermediate connecting portion 1213 and a free end of the second deformation portion 1212 facing away from the intermediate connecting portion 1213 may be directly hinged to form a triangular structure and be bent along the length direction of the hook portion 11; or further to the resilient wire in the hook 11. So set up, certain elastic potential energy can be stored to metal shrapnel after the installation to it takes place to warp under external force F's effect.
Further, before the metal dome is mounted, as shown in fig. 19 (a), the length of the first deformation portion 1211 and the length of the second deformation portion 1212 may be equal to each other (which may be referred to as L6), and may be greater than the length of the intermediate connection portion 1213 (L7). Wherein, L3 and L4 can satisfy the following relations: L7/L6 is more than or equal to 0.1 and less than or equal to 0.6. Of course, the thickness of the metal elastic sheet can be 0.1-0.8 mm.
Referring to fig. 20 to 24 together, fig. 20 is a schematic structural view of another embodiment of a spindle assembly according to the present application, fig. 21 is a schematic disassembled structural view of an embodiment of the spindle assembly in fig. 20, fig. 22 is a schematic sectional structural view of the spindle assembly in fig. 21, fig. 23 is a schematic disassembled structural view of another embodiment of the spindle assembly in fig. 20, and fig. 24 is a schematic sectional structural view of the spindle assembly in fig. 23.
Illustratively, in conjunction with fig. 20, the hinge mechanism 121 may include a first connecting block 1214, a second connecting block 1215, a hinge 1216, and a resilient assembly 1217. Wherein, the first connecting seat 1214 can be a part of the connecting portion 12; the second connecting seat 1215 may be connected to the hook 11 (or the metal elastic wire 115 therein), but may be formed as a part of the hook 11. Further, the first connecting seat 1214 and the second connecting seat 1215 are connected by the rotating shaft 1216, so that the first connecting seat 1214 and the second connecting seat 1215 can rotate relatively, and further, the hook 11 can rotate relative to the connecting portion 12 and the holding portion 13 by the rotating shaft mechanism 121. Referring to fig. 21 to 24, the elastic member 1217 is disposed to elastically abut between the first link seat 1214 and the second link seat 1215 so as to maintain the state of the hook 11 after rotating with respect to the holding part 13. So set up, when the user wore earphone 10, can adjust hook 11, make it more laminate ear 100, and then improve the comfort level and the stability of earphone 10 in the aspect of wearing.
In some embodiments, referring to fig. 21 and 22, the second connecting seat 1215 may be partially inserted into the first connecting seat 1214, so that the rotating shaft 1216 can be simultaneously inserted into the first connecting seat 1214 and the second connecting seat 1215, thereby achieving the rotation fit. Further, the first connecting seat 1214 may be provided with a receiving cavity 12141 with one end opened, and the elastic member 1217 may include an elastic member 12171 and a supporting member 12172. Wherein, the elastic member 12171 is disposed in the accommodating cavity 12141, and an end portion of the supporting member 12172 extends into the accommodating cavity 12141 to support the elastic member 12171; the other end of the supporting member 12172 supports the second connecting seat 1215.
It should be noted that: in order to facilitate the elastic component 1217 to be elastically supported between the first connecting seat 1214 and the second connecting seat 1215, the elastic member 12171 may be in a compressed state after the hinge mechanism 121 is assembled. Based on this, when the user wears the earphone 10, especially in the situation that the ear 100 of the user is large, the hook 11 and the elastic wire 115 therein can be forced to rotate relative to the holding portion 13, or have a tendency to rotate, so that the second connecting seat 1215 rotates relative to the first connecting seat 1214, and the elastic member 12171 is compressed by the propping member 12172. At this time, the elastic member 12171 acts against the supporting member 12172 to support the second connecting holder 1215 so that at least the hook 11 is more fitted to the ear 100 of the user based on newton's third law.
In other embodiments, referring to fig. 23 and 24, the end of the top holding member 12172 facing away from the elastic member 12171 may be a sphere, a cylinder, etc., and the end of the second connecting seat 1215 facing away from the elastic wire 115 may be provided with a plurality of grooves distributed along the circumference of the rotating shaft 1216. Wherein, the propping piece 12172 can be partially clipped into the groove under the action of the elastic force of the elastic piece 12171. In other words, after the hook 11 is rotated to different angles relative to the holding part 13, the supporting pieces 12172 can be respectively clipped into different grooves, thereby achieving the purpose of multi-stage adjustment.
Those skilled in the art will readily understand that the auxiliary portion 17 can also adopt the solutions in the foregoing embodiments to realize a flexible and adjustable adaptive structure, which is not described herein in detail.
Referring to fig. 25, fig. 25 is a schematic cross-sectional structure diagram of any embodiment of the earphone provided by the present application in the XY plane.
In some embodiments, the earphone 10 may be an air-guide earphone, and for this example, the holding portion and the components such as the movement and the main board thereof are exemplarily described as follows:
referring to fig. 25, the holding portion 13 may include an inner housing 131 and an outer housing 132, which are connected to form a cavity structure for receiving the core 14, the main board 15, and other components. It should be noted that: when the user wears the earphone 10, it may be mainly the inner case 131 that is in contact with the user's ear 100. In this case, since a large number of electronic components having different sizes and shapes are often integrated on the main board 15, the inside of the cavity of the holding portion 13 becomes extremely complicated, which easily affects the acoustic performance of the earphone 10. For this purpose, in this embodiment, a partition 133 is provided inside the holding portion 13 to separate the movement 14 from the main board 15, and to form a cavity 200 independent of the main board 15. The cavity 200 may have a relatively smooth inner wall. With this arrangement, the cavity 200 can be protected from the main board 15 and the electronic components thereon, so that the acoustic performance of the earphone 10 can be effectively improved.
As an example, the partition 133 may be directly connected with the movement 14, for example, the two are glued, so that the two directly form the cavity 200, wherein the partition 133 and the movement 14 enclose an inner wall forming the cavity 200, so as to avoid sharp structures such as right angles, sharp corners, and the like as much as possible. Further, the edges of the two parts may be wrapped with an elastic member (not shown) to form an interference fit with the inner wall of the holding portion 13, so as to achieve an acoustic seal.
The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes that can be directly or indirectly applied to other related technologies, which are made by using the contents of the present specification and the accompanying drawings, are also included in the scope of the present application.
