Description

Technical Field

[0001] This invention relates to the field of headphone technology, and more particularly to a headphone and headphone assembly. Background Technology

[0002] In related technologies, clip-on earphones that clip onto a user's ear typically include a clamping component and a sound-generating module. The sound-generating module is located within the clamping component for vibration to produce sound. The clamping component is often designed with a "U"-shaped structure or a U-shaped structure, allowing the opposite ends of the clamping component to open and close elastically. By using the clamping action of the clamping component on the auricle, the earphones are held in place on the user's ear. However, relying on the clamping force of the clamping component to hold the earphones in place can easily cause ear pain if the clamping force is too great, while if the clamping force is too small, the earphones can easily fall out of the ear. Summary of the Invention

[0003] This invention discloses an earphone and earphone assembly that can be stably worn on the human ear and can avoid pain caused by clamping force on the human ear.

[0004] To achieve the above objectives, in a first aspect, the present invention discloses an earphone, comprising:

[0005] The earphone body is configured to fit within the concha of the human ear and abut against the connection between the antihelix and the tragus of the human ear; the earphone body has a sound outlet.

[0006] The earphone tail hook includes a connecting part and a bent part. The connecting part is connected to the outer periphery of the earphone body. The bent part is connected to the connecting part and bent relative to the connecting part to form a hook space. The hook space is configured to accommodate the helix of a human ear so that the bent part at least partially conforms to the helix of a human ear. The end of the bent part opposite to the connecting part is set to conform to the back of the human ear.

[0007] When the earphone is worn on a human ear, the earphone has a first direction, a second direction, and a third direction upward limitation relative to the human ear. The first direction limitation is achieved at least by the earphone body fitting against the human concha cavity and one end of the bent portion away from the connecting part fitting against the back of the human ear. The second direction and the third direction upward limitation are achieved at least by the earphone body fitting against the connection point between the human antihelix and the human antitragus, and the bent portion fitting at least partially against the human antihelix.

[0008] The first direction, the second direction, and the third direction are perpendicular to each other.

[0009] As an optional implementation, in an embodiment of the first aspect of the present invention, the earphone body has a protruding fitting portion on the side facing the human concha cavity, the fitting portion being configured to fit into the human concha cavity.

[0010] As an optional implementation, in an embodiment of the first aspect of the present invention, the headphone body includes a first part and a second part, the fitting part is disposed on the side of the first part facing the human concha cavity, and the outer periphery of the first part is configured to abut against the connection between the human antihelix and the human antitragus.

[0011] The second part is connected to the side of the first part that is away from the human concha cavity;

[0012] The connecting portion is connected to the second part at a position near the connection between the antihelix and the tragus of the human body, or the connecting portion is connected to the second part at a position near the connection between the antihelix and the tragus of the human body at the connection between the first part and the second part.

[0013] As an optional implementation, in an embodiment of the first aspect of the present invention, the first part is a conical structure, and the cross-section of the first part gradually decreases along the direction from the first part to the second part.

[0014] As an optional implementation, in an embodiment of the first aspect of the present invention, the sound outlet of the sound hole is located on the side of the first part that faces the human concha cavity, and the sound outlet is disposed facing the human ear canal.

[0015] As an optional implementation, in an embodiment of the first aspect of the present invention, the earphone body is further configured to fit against the side of the human ear helix facing the human antitragus, so that the earphone body fits against the connection between the human antitragus and the human antitragus, and the bent portion at least partially fits against the human ear helix to jointly limit the earphone in the second direction.

[0016] As an optional implementation, in an embodiment of the first aspect of the present invention, the bending portion includes a bending portion and an overlapping portion, the bending portion connecting the overlapping portion and the connecting portion, the bending portion being used to fit against the helix of a human ear, and the overlapping portion being used to fit against the back of a human ear.

[0017] As an optional implementation, in an embodiment of the first aspect of the present invention, the overlapping portion and the connecting portion are respectively located on two opposite sides of the bent portion, and when the earphone is worn on a human ear, the connecting portion and the overlapping portion are arranged opposite to each other along the first direction.

[0018] In a second aspect, the present invention discloses an earphone assembly, the earphone assembly including an earphone case and earphones as described in the first aspect above, the earphones being disposed in the earphone case.

[0019] As an optional implementation, in an embodiment of the second aspect of the present invention, the earphone further includes a first magnet;

[0020] The earphone case has a second magnet, the first magnet and the second magnet having opposite polarities, to provide a force for fixing the earphones to the receiving slot.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention provides an earphone and earphone assembly. The earphone body fits snugly against the concha of the human ear, with one end of the bent portion away from the connecting part fitting against the back of the ear. This restricts the earphone's freedom of movement in the first direction of the ear, i.e., the thickness direction of the ear. Since the connection between the antihelix and the antitragus, and the end of the antihelix near the earlobe, are inclined relative to the width and height directions of the ear, the earphone body abuts against the connection between the antihelix and the antitragus, and the bent portion fits against the antihelix, thus restricting the earphone's freedom of movement in the second and third directions of the ear, thereby ensuring a stable fit. This invention eliminates the need for clamping force; by fitting the earphone parts against different parts of the ear, a stable fit is achieved, replacing the ear pain caused by clamping in related technologies.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 For the purpose of identifying the terminology used in this invention, Figure 1 The diagram illustrates the specific structure of the human ear and a Cartesian coordinate system based on the human ear. It can be understood that the X0 and X1 directions are located along the height of the human ear (100), and the Y0 and Y1 directions are located along the width of the human ear (100).

[0032] In this design, the thickness direction of the human ear 100 is perpendicular to the paper surface. The thickness direction, height direction, and width direction of the human ear 100 are all mutually perpendicular. The thickness direction of the human ear 100 includes the Z0 direction and the Z1 direction. The Z0 direction points away from the paper surface, and the Z1 direction points inwards into the paper surface. The side pointed to by the Z0 direction of the human ear 100 corresponds to the front side of the human ear 100, and the side pointed to by the Z1 direction corresponds to the back side of the human ear 100. Figure 1 The middle view is of the human ear 100 viewed from the front to the back of the human ear 100, that is, from the perspective along the Z1 direction.

[0033] The human ear 100 has a helix 101, a crus of the helix 102, an antihelix 103, an antitragus 104, a concha 105, an earlobe 106, an ear canal 107, and the back of the ear (not shown). Among them, the concha has a certain depth and volume in three-dimensional space.

[0034] Please see Figures 2 to 5In a first aspect, the present invention provides an earphone. The earphone 10 includes an earphone body 11 and an earphone hook 12. The earphone body 11 is configured to fit against the concha 105 of a human ear and abut against the connection between the antihelix 103 and the tragus 104 of a human ear. The earphone body 11 has a sound outlet, and the earphone hook 12 includes a connecting portion 121 and a bent portion 122. The connecting portion 121 is connected to the outer periphery of the earphone body 11, and the bent portion 122 is connected to the connecting portion 121 and bent relative to the connecting portion 121 to form a hook space. The hook space is configured to accommodate the helix 101 of a human ear, such that the bent portion 122 at least partially fits against the helix 101 of a human ear, and the end of the bent portion 122 opposite to the connecting portion 121 is used to fit against the back of the human ear.

[0035] When the earphone 10 is worn on the human ear 100, the earphone 10 has a first direction, a second direction, and a third direction upward limitation relative to the human ear 100. The first direction limitation is achieved at least by the earphone body 11 fitting against the human concha 105 and one end of the bent portion 122 fitting against the back of the human ear. The second direction and third direction upward limitation are achieved at least by the earphone body 11 fitting against the connection between the human antihelix 103 and the human antitragus 104, and the bent portion 122 fitting at least partially against the human helix 101.

[0036] Understandably, the headphone body 11 is located in front of the human ear 100, and the sound outlet is located in the headphone body 11 so that the human ear 100 can receive the sound emitted by the speaker module inside the headphone 10. The connecting part 121 of the headphone tail hook 12 is connected to the headphone body 11, and the connecting part 121 is located in front of the human ear 100. The bent part 122 is bent relative to the connecting part 121 and forms a hook space that can accommodate the human ear helix 101. That is to say, the bent part 122 goes around the human ear helix from the front of the human ear 100 and extends to the back of the human ear 100.

[0037] Figure 2 The diagram illustrates the state of the earphone 10 when worn on the left ear of a human body. For example, the first direction can be the thickness direction of the left ear, and may include Z0 and Z1 directions; the second direction can be the width direction of the left ear, and may include... Figure 2 In the Y0 and Y1 directions, the third direction can be the height direction of the left ear of the human body, and the third direction can include Figure 2 The X0 and X1 directions in the equation.

[0038] Specifically, the earphone body 11 extends into the ear and fits against the concha 105, restricting the movement of the earphone 10 in the Z1 direction. Meanwhile, the end of the bent portion 122 of the earphone tail hook 12 facing away from the connecting portion fits against the back of the ear, restricting the movement of the earphone 10 along the Z0 direction. These factors together restrict the degree of freedom of the earphone 10 in the first direction. It is understood that the connection point between the antihelix 103 and the antitragus 104, as well as the end of the antihelix 101 adjacent to the earlobe 106, is inclined relative to the height and width directions of the ear 100. Therefore, when the earphone body 11 abuts against the connection point between the antihelix 103 and the antitragus 104, it restricts the movement of the earphone 10 along the Z0 direction. Figure 2 The movement in the X0 direction, and the movement of the earphone 10 along the X0 direction. Figure 2 Movement in the Y0 direction, while the bent portion 122 of the earphone tail hook 12 fits against the end of the human ear helix 101 near the human earlobe 106, can limit the movement of the earphone 10 along the Y0 direction. Figure 2 The movement in the X1 direction, and the movement of the earphone 10 along the Figure 2 The movement in the Y1 direction together restricts the degrees of freedom of the earphone 10 in the second and third directions.

[0039] As can be seen, this application employs a method where the main body 11 of the earphone is inserted into the ear and fits against the concha cavity 105 of the human body. The end of the bent portion 122 of the earphone tail hook 12 away from the connecting portion fits against the back of the human ear, which can restrict the rotation of the earphone 10 around the second direction (Y0, Y1 direction) and the rotation of the earphone 10 around the third direction (X0, X1 direction). The main body 11 of the earphone abuts against the connection between the antihelix 103 and the antitragus 104 of the human body. The bent portion 122 of the earphone tail hook 12 fits against the end of the helix 101 near the earlobe 106 of the human body, which can restrict the rotation of the earphone 10 around the first direction (Z0, Z1 direction).

[0040] Thus, by fitting the various parts of the earphone 10 to the various parts of the human ear 100, the earphone 10 can be stably worn on the human ear 100. Since the earphone 10 is not fixed by clamping force when worn on the human ear 100, it helps to avoid pain caused by clamping force on the human ear 100.

[0041] Optionally, the speaker module is located inside the headphone body 11. Since the movement of the headphone 10 in the direction of gravity (X0 direction) is mainly restricted by the connection between the headphone body 11 and the antihelix 103 and the tragus 104 of the human body, and the headphone body 11 is closer to the human ear canal 107 than the headphone tail hook 12, placing the speaker module inside the headphone body 11 not only helps to improve the stability of the headphone 10 when worn on the human ear 100, but also facilitates the transmission of sound emitted by the speaker module.

[0042] In some embodiments, the earphone body 11 has a protruding fitting portion 11a on the side facing the human concha 105, and the fitting portion 11a is configured to fit against the human concha 105. As mentioned above, the human concha 105 is a recessed structure with a certain depth. In order to facilitate the fitting of the earphone body 11 with the human concha 105, the earphone body 11 may have a protruding fitting portion 11a, which can extend into the human concha 105 along the Z1 direction and fit against the human concha 105.

[0043] Furthermore, the surface of the fitting part 11a that is used to fit the human concha 105 is arc-shaped. This not only allows the fitting part 11a to fit tightly with the human concha 105, but also increases the area of ​​the fitting part 11a in the human concha 105, while achieving a smooth transition of the fitting surface of the fitting part 11a, thus avoiding scratching the human ear 100.

[0044] Specifically, the fitting part 11a can fit into the position of the human ear concha 105 along the X0 and Y0 directions, that is, the fitting part 11a is completely fitted into the human ear concha 105, thereby further restricting the movement of the earphone 10 in the X0 and Y0 directions, so that the earphone 10 can be worn more securely in the human ear 100.

[0045] In some embodiments, the earphone body 11 includes a first portion 111 and a second portion 112. A fitting portion 11a is disposed on the side of the first portion 111 facing the human concha 105. The outer periphery of the first portion 111 is configured to abut against the connection between the human antihelix 103 and the human antitragus 104. The second portion 112 is connected to the side of the first portion 111 facing away from the human concha 105. A connecting portion 121 is connected to the second portion 112 near the connection between the human antihelix 103 and the human antitragus 104, or, alternatively, the connecting portion 121 is connected to the second portion 112 near the connection between the first portion 111 and the second portion 112. It is understandable that the first part 111 is located on the side of the human antitragus 104 pointing in the Z1 direction, that is, the rear side of the human antitragus 104, so that the fitting part 11a fits against the human concha cavity 105. At the same time, the outer periphery of the first part 111 can abut against the connection between the human antihelix 103 and the human antitragus 104. The connecting part 121 is connected to the second part 112 near the connection between the human antihelix 103 and the human antitragus 104, or near the connection between the first part 111 and the second part 112. Then, under the action of gravity, the earphone tail hook 12 drives the earphone body 11 to be supported at the connection between the human antihelix 103 and the human antitragus 104, which helps to ensure the wearing stability of the earphone 10.

[0046] Furthermore, the first part 111 has a conical structure, specifically roughly in the shape of a conical block, to fit the shape of the human auricular cavity 105. Along the direction from the first part 111 to the second part 112, the cross-section of the first part 111 gradually decreases. Because the posterior side of the connection between the human antihelix 103 and the human antitragus 104 faces... Figure 2 The ear is concave in the Y0 direction. Therefore, by designing the first part 111 as a conical structure, the structure of the first part 111 matches the inner shape of the connection between the antihelix 103 and the tragus 104. This not only allows the first part 111 to conform to the structure of the human ear 100 and facilitates the first part 111 to abut against the end of the antihelix 103 near the tragus 104, but also helps to prevent the first part 111 from falling out by using the antihelix 103, thus restricting the earphone 10 from moving along the Y0 direction. Figure 2 Motion in the Z0 direction.

[0047] In some embodiments, the sound outlet of the sound hole is located on the side of the first part 111 facing the human concha 105, and the sound outlet is positioned facing the human ear canal 107. Compared to other parts, the first part 111 is closer to the human ear canal 107. Therefore, by opening the sound outlet on the side of the first part 111 facing the human concha 105 and positioning the sound outlet facing the human ear canal 107, it is beneficial for the sound emitted by the speaker module to be transmitted to the external environment through the sound hole and then directly transmitted to the human ear canal 107, so that the user can hear the sound more clearly.

[0048] Understandably, the sound outlet is not blocked by any part of the human ear, so that the sound emitted by the speaker module can be transmitted to the external environment through the sound outlet.

[0049] In one example, when the earphone 10 is worn on a human ear 100, viewed along the direction from the first part 111 to the second part 112, the first part 111 covers part of the human ear canal 107, the fitting part 11a may be located in the middle of the first part 111, and the sound outlet may be located in the part of the first part 111 located on the outer periphery of the fitting part 11a, and the sound outlet is positioned directly facing the human ear canal 107.

[0050] Another example is that the sound outlet is located on the outer periphery of the first part 111 near the human ear canal 107.

[0051] In some embodiments, the earphone body 11 is further configured to fit against the side of the human ear helix 102 facing the human antitragus 104, so that the earphone body 11 fits against the connection between the human antitragus 103 and the human antitragus 104, and the bent portion 122 at least partially fits against the human ear helix 101, together achieving the limitation of the earphone 10 in the second direction. It can be understood that the side of the human ear helix 102 facing the human antitragus 104, that is, the lower side of the human ear helix 102, when the earphone 10 is worn on the human ear 100, can have the first portion 111 fitted against the lower side of the human ear helix 102, so that together with the bent portion 122 of the earphone tail hook 12, the earphone 10 is limited in the direction of movement. Figure 2 The movement is in the Y1 direction to ensure that the earphone 10 can be stably worn on the human ear 100.

[0052] Specifically, the fitting portion 11a of the earphone body 11 is also used to fit against the side of the human ear helix 102 facing the human antitragus 104, so as to restrict the earphone 10 along the earphone tail hook 12 together with the bent portion 122 of the earphone tail hook 12. Figure 2 Motion in the Y1 direction.

[0053] In some embodiments, the length of the connecting portion 121 of the earphone tail hook 12 is adjustable so that the distance from the bent portion 122 to the earphone body 11 is adjustable so that the bent portion 122 fits against the human ear helix 101.

[0054] In some embodiments, the earphone tail hook 12 is generally U-shaped, that is, the bent portion 122 may include a bent portion 1221 and an overlapping portion 1222. The bent portion 1221 connects the overlapping portion 1222 and the connecting portion 121. The bent portion 1221 is used to conform to the helix of the human ear, and the overlapping portion 1222 is used to conform to the back of the human ear. It is understood that the overlapping portion 1222 is located on the back side of the human ear 100, and the bent portion 1221 extends from the front side of the human ear 100 to the back side of the human ear 100, connecting the connecting portion 121 and the overlapping portion 1222. The bent portion 1221 conforms to the helix of the human ear, close to the earlobe, to limit the earphone 10 from moving in any direction. Figure 2 Restrictions in the X1 and Y1 directions.

[0055] For example, the end face of the overlapping portion 1222 can be fitted to the back of a human ear, or the circumferential surface of the overlapping portion 1222 can be fitted to the back of a human ear.

[0056] Furthermore, the overlapping portion 1222 and the connecting portion 121 are located on opposite sides of the bent portion 1221. When the earphone 10 is worn on the human ear 100, the connecting portion 121 and the overlapping portion 1222 are arranged opposite each other along the first direction. That is to say, when looking from the second part 112 to the first part 111, the extension direction of the overlapping portion 1222 is parallel to or slightly angled to the length direction of the connecting portion 121, so that the connecting portion 121 can be projected onto the overlapping portion 1222. This is beneficial because whether the earphone 10 is worn on the left or right ear, when the earphone body 11 abuts against the connection between the antihelix 103 and the antitragus 104, and the bent portion 1221 is attached to the end of the antihelix 101 near the earlobe, the overlapping portion 1222 can abut against the back of the ear. This makes the earphone 10 suitable for both left and right ears, improving the universal compatibility of the earphone 10.

[0057] In some embodiments, a charging contact is provided on the side of the second part 112 of the earphone body 11 away from the first part 111, or a charging contact is provided on the side of the overlapping part 1222 away from the earphone body 11 and the connecting part 121. The charging contact is electrically connected to the speaker module inside the earphone body 11. It can be understood that when the earphone 10 is worn on the human ear 100, the side of the second part of the earphone body 11 away from the first part, and the side of the overlapping part 1222 away from the earphone body 11 and the connecting part 121, are not in contact with the human skin. Therefore, providing charging contacts at these two locations helps to reduce the discomfort of human skin contacting the charging contacts and improves the user's wearing experience.

[0058] Secondly, the present invention also provides an earphone assembly, which includes an earphone case and the aforementioned earphones 10, wherein the earphones 10 are disposed in the earphone case. Specifically, the earphone assembly may include one or more earphones 10, all of which are stably worn on the human ear and help to avoid pain in the human ear caused by the clamping force exerted by the earphones 10 when worn on the human ear.

[0059] Understandably, the headphone case is used to store one or more headphones.

[0060] For example, the headphone assembly includes a headphone case and two earphones 10, and the two earphones 10 can be stored together in the headphone case, and the two earphones 10 can be worn on the left and right ears of the human body respectively.

[0061] In some embodiments, the earphone 10 further includes a first magnet. The earphone case has a second magnet, the first magnet and the second magnet having opposite polarities, to provide a force to secure the earphone 10 to the receiving slot, ensuring that the earphone 10 cannot easily fall out of the earphone case, preventing loss, and also helping to ensure the electrical stability of the earphone 10 and the earphone case. Specifically, the first magnet can be located inside the earphone body 11 or inside the earphone tail hook 12.

[0062] The foregoing has provided a detailed description of the earphones and earphone components disclosed in the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the embodiments above are only for the purpose of helping to understand the earphones and earphone components of the present invention and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
