## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to an ear wing used for an earphone or hearing aid.
Background of the Related Art
In general, an earphone is a sound transmitting device widely used for communication, learning or listening to music, and the like, and there are a variety of types of earphones such as open type earphones, carnal type earphones, ear-hanging type earphones, and so on.
As various portable multimedia devices have been prevailed, speakers embedded in the multimedia devices (for example, smartphone) are not used so as to prevent damages caused by the usage thereof from being given to other persons. Instead of the speakers, an earphone is generally used in such a manner as to be connected to an earphone jack mounted on the multimedia device. Therefore, the demand on the earphone is expected to be gradually increased in the future.
However, eartips of recently launched earphones, which are worn on the ears of users, have almost uniform shapes, and when considering different ear structures and features according to users, accordingly, it is difficult that the earphones are fixed to the ears of the users.
So as to solve the above-mentioned problems, accordingly, there is proposed U.S. Pat. No. 9,036,852 (hereinafter, referred to as ‘conventional practice’). According to the conventional practice, an earpiece positioning and fixing structure is suggested.
In more detail, the earpiece positioning and fixing structure in the conventional practice includes an outer leg and an inner leg each having one end coupled to different portions (one side and the other side) of an eartip and the other end coupled to each other, wherein the outer leg is located along the inner side of the antihelix and the inner leg comes into contact with the base of an external ear.
So as to fix the earpiece to the external ear, according to the conventional practice, the outer leg extended from one side of the eartip comes into contact with the antitragus formed on the end of the antihelix, and the inner leg extended from the other side of the eartip comes into contact with the tragus. If the earpiece is worn for long hours, accordingly, the portions around the antigragus and the tragus may be compressed against the outer leg and the inner leg, thus causing wearing comfort to be bad and making the user feel uncomfortable.

Further, the tragus 13 is a triangular protrusion formed in front of the acoustic meatus 16, the concha 15 is a deep depression located above the antitragus 12, and the crus of helix 14 is the front portion of the helix 17 which starts at the bottom portion of the concha 15.
2. Explanations on Components of Ear Wing and Worn State of Ear Wing
FIG. 2 is a view showing components of an ear wing according to a first embodiment of the present invention, FIG. 3 is a view showing components of an ear wing according to a second embodiment of the present invention, FIG. 4 is a view showing a state wherein the ear wing according to the second embodiment of the present invention is worn on a user's ear, FIG. 5 is a view showing a state wherein the ear wing according to the second embodiment of the present invention is worn on the user's ear through the deformation of a deformable portion, and FIG. 6 is a view showing a state wherein a first variable part of the ear wing according to the second embodiment of the present invention is worn on the user's ear.
Referring to FIGS. 2 to 6, an ear wing 100 according to the present invention largely includes a coupling portion 110, a deformable fixing portion 120, and a variable portion 130.
As shown in FIG. 2, the coupling portion 110 is coupled to a sound output device E, and accordingly, the coupling portion 110 has a space adapted to accommodate a portion of the sound output device E thereinto. Further, the coupling portion 110 may be coupled rotatably to the sound output device E.
As shown in FIG. 2, the deformable fixing portion 120 is located with a given curvature inside the antihelix 11 in such a manner as to allow the coupling portion 110 to be located fixedly to the external ear 10.
In this case, desirably, the deformable fixing portion 120 is not brought into contact with the region around the antitragus 12 located on the end portion of the antihelix 11. The reason is that the pressure against the region around the antigragus 12 can be minimized when the sound output device E is fixed through the deformable fixing portion 120.
Further, the deformable fixing portion 120 is changed in shape in accordance with the shape of the antihelix 11 and is desirably made of an elastic material or a soft material (for example, silicone) so as to improve the wearing comfort thereof.
As shown in FIG. 4, the deformable fixing portion 120 is located inside the antihelix 11, so that as a portion of the coupling portion 110 is inserted into the acoustic meatus 16, the coupling portion 110 can be stably fixed to the external ear 10. To this end, as shown in FIG. 2, the deformable fixing portion 120 includes a fitting portion 121 and a deformable portion 122.
The fitting portion 121 is extended from one side of the deformable fixing portion 120 in such a manner as to be fitted to the space between the antihelix 11 and the crus of helix 14. The formation of the fitting portion 121 improves the fixing force of the coupling portion 110 to the external ear 10 and the fixing force of the sound output device E coupled to the coupling portion 110.
The deformable portion 122 is extended from the other side of the deformable fixing portion 120 toward the antitragus 12 in such a manner as to be located inside the antihelix 11, and further, the deformable portion 122 is deformed in accordance with the shape of the antihelix 11. That is, the deformable portion 122 is located with a given curvature between the antihelix 11 and the concha 15 in such a manner as to be deformed appropriately with respect to the shape of the antihelix 11.
The variable portion 130 connects the coupling portion 110 and the deformable fixing portion 120 to each other in such a manner as to support the deformable fixing portion 120 thereagainst, so that the coupling portion 110, the deformable fixing portion 120, and the variable portion 130 are formed integrally with each other.
In this case, the variable portion 130 has at least one or more variable parts changed in shape according to the deformation of the deformable fixing portion 120, and in the same manner as the deformable fixing portion 120, the variable portion 130 is desirably made of an elastic material or a soft material so as to improve the wearing comfort thereof.
The variable portion 130 is extended from one side of the coupling portion 110 and connected to the deformable fixing portion 120, so that a portion of the coupling portion 110 is not brought into contact with the region around the antihelix 11, thus minimizing the pressure applied to the region around the antihelix 11 and the tragus 13.
Further, as shown in FIGS. 2 and 3, the variable portion 130 includes a first variable part 131.
The first variable part 131 connects one side of the coupling portion 110 and the surrounding portion of the fitting portion 121 formed on one side of the deformable fixing portion 120 to each other, and further, the first variable part 131 is changed in shape through the deformation of the deformable fixing portion 120.
As shown in FIG. 6, desirably, the first variable part 131 can be curved with a curvature in accordance with the protruding degree of the crus of helix 14. Accordingly, the first variable part 131 is provided appropriately in accordance with the shape of the crus of helix 14 in such a manner as to avoid the interference with the crus of helix 14, thus more stably fixing the deformable fixing portion 120 to the inside of the antihelix 11. That is, the first variable part 131 is curved outwardly from the external ear 10 with a curvature in correspondence to the outwardly protruding shape of the crus of helix 14 from the external ear 10.
According to the second embodiment of the present invention, as shown in FIG. 3, the variable portion 130 further includes a second variable part 132. The second variable part 132 connects one side of the coupling portion 110 and the other side of the deformable fixing portion 120 to each other, and in the same manner as the above-mentioned first variable part 131, the second variable part 132 is changed in shape through the deformation of the deformable fixing portion 120.
Like this, the ear wing according to the present invention is configured wherein the coupling portion 110 is rotatably coupled to the sound output device E in such a manner as to be adequate to the structure or features of the external ear 10 of a user, and accordingly, the deformable fixing portion 120 is deformed, so that through the deformation of the deformable fixing portion 120, the variable portion 130 is changed in shape to allow the coupling portion 110 and the sound output device E to be more stably located fixedly to the external ear 10.
Accordingly, the coupling portion 110 and the sound output device E are stably fixed to the external ear 10 by means of the deformable fixing portion 120 and the variable portion 130, so that even during the user's outside activities, the coupling portion 110 and the sound output device E are not easily escaped from the external ear 10 of the user.
Moreover, the variable portion 130 has a variable space S formed between the first variable part 131 and the second variable part 132 in such a manner as to be changed in shape by means of the first variable part 131 and the second variable part 132, and accordingly, the shape of the variable portion 130 is changed in shape to correspond to the width of the concha 15. Through the formation of the variable space S, further, the first variable part 131 and the second variable part 132 may be changed in shape by means of the deformation of the deformable fixing portion 120 or the structure of the external ear 10 (for example, the structures of the antihelix 11 and the crus of helix 14 and the like).
That is, the shapes or structures of the antihelix 11 are different according to the users who wear the ear wing 100 according to the present invention, and accordingly, as shown in FIG. 5, the deformable portion 122 is deformed correspondingly to the shape of the antihelix 11 and located inside the antihelix 11 in the state wherein the fitting portion 121 is fitted to the space between the antihelix 11 and the crus of helix 14. As a result, the first variable part 131, the second variable part 132, and the variable space S are changed in shape.
Further, the variable portion 130 includes other variable parts like the first variable part 131 and the second variable part 132 as mentioned above, and accordingly, the number of variable spaces S formed between the variable parts may be increased in accordance with the number of variable parts.
As mentioned above, the ear wing 100 according to the present invention is configured wherein the coupling portion 110 and the sound output device E are stably contactedly fixed to the external ear 10 by means of the deformable fixing portion 120 and the variable portion 130, and further, the pressure applied to the surrounding portions of the antitragus 12 and the tragus 13 can be minimized through the structure of connecting the coupling portion 110 and the variable portion 130, so that wearing comfort becomes excellent and even if the user wears the ear wing 100 for long hours, he or she does not feel uncomfortable, thus optimizing the conveniences in use.
Further, the sound output device E fixed to the external ear 10 by means of the ear wing 100 according to the present invention may be an earphone or hearing aid, so that the ear wing 100 according to the present invention may be applied to a variety of sound output devices E.
As described above, the ear wing according to the present invention has the following advantages.
Firstly, the pressure applied to the surrounding portions of the antitragus and the tragus can be minimized through the structure of connecting the coupling portion and the variable portion, so that wearing comfort becomes excellent, and even if the user wears the ear wing for long hours, he or she does not feel uncomfortable, thus optimizing the conveniences in use.
Secondly, the coupling portion is rotatably coupled to the sound output device in such a manner as to be adequate to the structure or features of the external ear of the user, and accordingly, the deformable fixing portion is deformed, so that through the deformation of the deformable fixing portion, the variable portion is changed in shape to allow the coupling portion and the sound output device to be more stably located fixedly to the external ear.
Lastly, the coupling portion and the sound output device are stably fixed to the external ear by means of the deformable fixing portion and the variable portion, so that even during the user's outside activities, the coupling portion and the sound output device are not easily escaped from the external ear of the user.
