[0039] In order to illustrate the technical solutions described in this application, the following provides a detailed description in conjunction with specific drawings and embodiments.

[0040] First Embodiment

[0041] As Figures 1 - 9 shown, an embodiment of this application provides an ear support structure, including: an elastic sleeve body 1 and an elastic support body 2. The elastic support body 2 is disposed on the outer side surface of the elastic sleeve body 1, and the elastic support body 2 is fixedly connected to the elastic sleeve body 1, or the elastic support body 2 and the elastic sleeve body 1 are an integral structure and are integrally formed.

[0042] In the ear support structure provided in this embodiment, the elastic sleeve body 1 has a receiving cavity and a sound outlet nozzle opening 11, and the sound outlet nozzle opening 11 communicates with the receiving cavity. The receiving cavity is used to receive the head of the earphone 3, and the elastic sleeve body 1 and the head of the earphone 3 are relatively fixed by interference fit. The sound outlet nozzle opening 11 communicates with the receiving cavity. After the elastic sleeve body 1 is sleeved on the head of the earphone 3, the sound outlet nozzle of the earphone 3 faces the sound outlet nozzle opening 11. When the earphone 3 is an in-ear earphone, the sound outlet nozzle of the earphone 3 extends out of the receiving cavity of the elastic support body 2 from the sound outlet nozzle opening 11.

[0043] As Figure 3 and Figure 4 shown, the elastic sleeve body 1 is configured to be able to abut against the ear canal opening and tragus of the human ear; the elastic support body 2 protrudes along the first direction on the outer side surface of the elastic sleeve body 1 and is used to extend into the concha of the human ear and abut against the antitragus 4.

[0044] As Figure 1 shown, the first direction is the direction in which the elastic support body 2 protrudes outward away from the elastic sleeve body 1, and the included angle α between the first direction and the axial direction of the sound outlet nozzle opening 11 is 100° - 145°. Within this angle range, the elastic support body 2 can be adapted to the ears of most people. That is to say, within this angle range, after the ear support structure is installed on the earphone 3, the position where the elastic support body 2 of the ear support structure is located is adapted to the concha positions of most people, so that most people can obtain a better wearing experience without having to adjust the position of the elastic support body 2 on the earphone 3 by themselves.

[0045] Preferably, as Figure 5 and Figure 6 shown, the elastic support body 2 has a structure similar to a sand dune, and its outer contour surface is a curved surface.

[0046] Further, the elastic sleeve body 1 is provided with a mounting hole 15 and a rod opening 16. The rod opening 16 is used for the rod portion of the earphone 3 to extend out of the sleeve body. When assembling the elastic sleeve body 1 on the earphone 3, the rod portion of the earphone 3 is inserted into the accommodation cavity through the mounting hole 15 and extends out of the accommodation cavity through the rod opening 16. The head portion of the earphone 3 connected to the rod portion moves with the rod portion when the rod portion extends out of the accommodation cavity, and enters the accommodation cavity through the mounting hole 15, while the sound outlet nozzle of the head portion extends out of the accommodation cavity through the sound outlet nozzle opening 11. With such a setting, the sound outlet nozzle of the earphone 3 extends out of the sound outlet nozzle opening 11 of the ear support structure, and there is a relative limiting position between the sound outlet nozzle opening 11 and the sound outlet nozzle, which can limit the relative movement between the sound outlet nozzle and the ear support structure in the radial direction of the sound outlet nozzle; and the rod portion of the earphone 3 extends out of the rod opening 16, and there is a relative limiting position between the rod portion and the rod opening 16, which can limit the relative movement between the ear support structure and the earphone 3 in the radial direction of the rod portion. Therefore, between the ear support structure and the earphone 3, there are at least two relative limiting positions at least at the sound outlet nozzle and the rod portion, so that the ear support structure can be prevented from moving relative to the earphone 3, and the assembly stability between the ear support structure and the earphone 3 is improved.

[0047] Further, the diameter of the rod opening 16 is smaller than the diameter of the mounting hole 15, and the diameter of the rod opening 16 matches the size of the rod portion of the earphone 3, so that the inner side wall of the rod opening 16 can be attached to the outer side wall of the rod portion of the earphone 3.

[0048] Further, through the design of the size of the mounting hole 15, after the ear support structure is sleeved on the head portion of the earphone 3, a partial area of the head portion of the earphone 3 extends outside the mounting hole 15, so that a relative limiting position is added between the mounting hole 15 and the head portion of the earphone 3, which can limit the relative movement between the earphone 3 and the ear support structure in the radial direction of the mounting hole 15.

[0049] Further, the rod opening 16 is connected with a limiting cylinder 19, and the limiting cylinder 19 is used for wrapping at least part of the structure of the rod portion of the earphone 3. With such a setting, the contact area between the ear support structure and the rod portion of the earphone 3 is increased, so that the relative friction force between the ear support structure and the earphone 3 is increased, and the connection stability between the ear support structure and the earphone 3 is further improved.

[0050] The elastic support body 2 is a convex structure protruding outward from the outer side surface of the elastic sleeve body 1, and the outer contour surface of the elastic support body 2 is a curved surface. The shape and size of the elastic support body 2 should be adapted to the ear socket of the human ear.

[0051] To make the elastic support body 2 adapt to the ear sizes of most people, preferably, as Figure 5 shown, the length L1 of the elastic support body 2 in the first direction is 1.5 mm - 4.0 mm. This size has a relatively large influence on the depth of the elastic support body 2 extending into the ear socket.

[0052] Further, as Figure 6 shown, the length L3 of the elastic support 2 in the axial direction of the mounting hole 15 is 3 mm - 10 mm. If the length of the elastic support 2 in the axial direction of the mounting hole 15 is less than 3 mm, it is not conducive to the elastic support 2 fitting onto the antitragus 4. If the length of the elastic support 2 in the axial direction of the mounting hole 15 is greater than 10 mm, this dimension will be greater than the length of some people's ear canals in the same direction, affecting the wearing comfort.

[0053] Further, as Figure 5 shown, the length L2 of the elastic support 2 in the axial direction of the rod opening 16 is not greater than 13 mm. Or rather, defining a plane, the endpoint of the elastic support 2 at the farthest end in the first direction protruding from the elastic sleeve 1 and the axis of the rod opening 16 are both located in this plane, then the projection of the side of the elastic support 2 facing away from the elastic sleeve 1 on this plane is in the shape of a similar U-shaped line, and the size of the opening of this U-shaped line is not greater than 13 mm.

[0054] Further, the elastic sleeve 1 is provided with a microphone hole 12 and an air vent hole. The microphone hole 12 is opposite to the microphone position of the earphone 3, and the air vent hole is opposite to the air vent position of the earphone 3. Corresponding to the earphone 3 having a front cavity air vent and a rear cavity air vent, the air vent hole of the elastic sleeve 1 includes a front cavity air vent hole 13 and a rear cavity air vent hole 17.

[0055] Since the position of the front cavity air vent of some earphones 3 is relatively close to the position of the sound outlet nozzle, in a preferred embodiment, the front cavity air vent hole 13 is communicated with the sound outlet nozzle opening 11, which is convenient for production and manufacturing.

[0056] Further, since sensors are installed in some earphones 3 to detect whether the earphones 3 are well-fitted to the ears, some earphones 3 use infrared sensors. Correspondingly, the elastic sleeve 1 is provided with a sensor avoidance hole 14, and the sensor avoidance hole 14 is opposite to the sensor in the earphone 3. Specifically, the sensor avoidance hole 14 is opposite to the light outlet of the sensor in the earphone 3, so that the infrared light of the sensor can be directly emitted from the sensor avoidance hole 14.

[0057] The ear support structure is made of an elastic material to facilitate interference fit and fixation with the head of the earphone 3. Preferably, the ear support structure is made of a silicone elastic material, and there is an interference amount of 0.5 mm - 1.0 mm between the elastic sleeve body 1 and the head of the earphone 3. That is to say, in the design process, the contour shape of the inner wall of the accommodating cavity of the elastic sleeve body 1 is matched with the outer contour surface shape of the head of the earphone 3, and the size of the accommodating cavity of the elastic sleeve is uniformly expanded by 0.5 mm - 1.0 mm relative to the outer contour size of the head of the earphone 3. With such a setting, after the elastic sleeve body 1 is sleeved on the head of the earphone 3, the elastic sleeve body 1 will undergo a certain degree of elastic deformation, thereby increasing the relative acting force between the elastic sleeve body 1 and the earphone 3, increasing the friction force, and having stronger relative fixing stability, and it is not easy to have position deviation.

[0058] As Figure 7 shown, in a specific embodiment, the elastic support body 2 is a hollow structure, which has an inner cavity 21, and its inner cavity 21 can communicate with the accommodating cavity of the elastic sleeve body 1. With such a setting, the elastic deformation range of the elastic support body 2 can be increased, and the weight of the ear support structure can also be reduced. Of course, in other different embodiments, the elastic support body 2 can be a solid structure.

[0059] Second Embodiment

[0060] As Figure 10 and Figure 11 shown, an embodiment of the present application provides an ear support structure, which is an improved structure of the above first embodiment. The difference between the ear support structure provided in this embodiment and the ear support structure provided in the above first embodiment lies only in the content described below in this embodiment. For the parts not mentioned below, the ear support mechanism provided in this embodiment has the same features as the ear support structure provided in the above first embodiment, and will not be described in detail.

[0061] In the ear support structure provided in this embodiment, the rod opening 16 is not provided on the elastic sleeve body 1. That is to say, during the assembly of the elastic sleeve body 1 and the earphone 3, the head of the earphone 3 extends into the accommodating cavity of the elastic sleeve body 1 through the mounting hole 15, and the mounting hole 15 of the earphone sleeve body wraps around the connection between the head and the rod of the earphone 3. This design is more suitable for semi-in-ear earphones because the rod designs of different models of semi-in-ear earphones vary greatly. Therefore, if the rod opening 16 needs to be opened, the elastic sleeve body 1 needs to be designed separately for each model of semi-in-ear earphone. However, the head designs of semi-in-ear earphones vary relatively little. Therefore, the elastic sleeve body 1 is only sleeved on the head of the semi-in-ear earphone, making the universality of the elastic sleeve body 1 higher, and one ear support structure can be applicable to multiple different models of semi-in-ear earphones.

[0062] To improve the connection stability between the ear support structure and the earphone 3, preferably, a limiting convex ring 18 for covering the edge of the sound outlet nozzle of the earphone 3 is provided on the inner wall of the sound outlet nozzle opening 11. Specifically, the limiting convex ring 18 and the elastic sleeve body 1 are of an integral structure. When the ear support structure is sleeved on the head of the earphone 3, since the semi-in-ear earphone does not have an ear cap 31, the sound outlet nozzle does not extend out of the accommodation cavity from the sound outlet nozzle opening 11, but abuts against the limiting convex ring 18, and the limiting convex ring 18 contacts the edge of the sound outlet nozzle of the earphone 3, playing a certain limiting role.

[0063] Preferably, the distance L4 between the inner ring surface and the outer ring surface of the limiting convex ring 18 is 0.5 mm - 1.0 mm, and can be, for example, 0.5 mm, 0.7 mm, 0.9 mm or 1.0 mm. Within this size range, the limiting convex ring 18 can completely wrap the edge area of the sound outlet nozzle.

[0064] Third Embodiment

[0065] As Figure 12 and Figure 13 shown, this embodiment provides an earphone, including an earphone body 51. The earphone body 51 is provided with a sound outlet nozzle and a support portion 52. The support portion 52 is used to extend into the ear socket of the human ear and abut against the antitragus. The support portion 52 protrudes along a first direction on the outer side surface of the earphone body 51, and the included angle β between the first direction and the axis direction of the opening of the sound outlet nozzle is 100° - 145°. Within this angle range, the support portion 52 can be adapted to the ears of most people. That is to say, within this angle range, when the earphone is worn on the ear, the position of the support portion 52 on the earphone body 51 is adapted to the ear socket positions of most people, so that most people can obtain a better wearing experience.

[0066] Furthermore, the earphone body 51 includes a head and a rod portion, and the support portion 52 is provided on the head.

[0067] It should be noted that, preferably, the structural shape and size of the support portion 52 provided in this embodiment are the same as those of the elastic support body in the ear support structures provided in the above-mentioned first embodiment and second embodiment. That is to say, the support portion 52 at least conforms to one of the following characteristics: the support portion 52 is a convex structure protruding outward from the outer side of the earphone body 51, and the outer contour surface of the support portion 52 is a curved surface, and the shape and size of the support portion 52 should be adapted to the concha of the human ear. The length of the support portion 52 in the first direction is 1.5 mm - 4.0 mm, and the length of the support portion 52 in the axial direction of the rod portion is not greater than 13 mm. Or, defining a plane, the end point of the outermost end of the support portion 52 protruding from the earphone body 51 in the first direction and the axis of the rod portion of the earphone body are both located in this plane, then the projection of the side surface of the support portion 52 facing away from the earphone body 51 in this plane is in a shape similar to a U-shaped line, and the size of the opening of this U-shaped line is not greater than 13 mm.

[0068] Further, the earphone further includes an ear cap 31. The ear cap 31 is sleeved at the sound outlet nozzle, and the axis of the opening of the ear cap 31 is coaxially arranged with the axis of the opening of the sound outlet nozzle. In Figure 12 and Figure 13 the ear cap 31 blocks the sound outlet nozzle, but the axis position of the opening of the sound outlet nozzle can be judged from the axis position of the opening of the ear cap 31.

[0069] In a feasible implementation manner, the earphone body 51 and the support portion 52 are of an integral structure and can be manufactured by an integral molding process during the manufacturing process. Or, the earphone body 51 and the support portion 52 are respectively manufactured and fixedly connected into an integral structure, that is, the support portion 52 is directly connected to the earphone body 51. In this implementation scheme, the support portion 52 can be made of a hard material, such as the same material as the outer shell of the earphone body 51; the support portion 52 can also be made of a flexible material, such as silicone, rubber and other materials.

[0070] In another feasible implementation manner, the earphone further includes a socket portion, and the support portion 52 is connected to the earphone body 51 through the socket portion. Specifically, the socket portion is fixedly connected to the support portion 52, and the socket portion is wrapped around the outside of the head of the earphone body 51 to be relatively fixed to the head of the earphone body 51.

[0071] Preferably, the socket portion is the elastic sleeve body in the ear support structure provided in the above-mentioned embodiment one or the embodiment, and the support portion 52 is the elastic support body in the ear support structure provided in the above-mentioned embodiment one or the embodiment.

[0072] Specifically, when the earphone is an in-ear earphone, the socket portion preferably adopts the elastic sleeve body in the ear support structure provided in the above-mentioned first embodiment, and the support portion 52 preferably adopts the elastic support body in the ear support structure provided in the above-mentioned first embodiment.

[0073] When the earphone is a semi-in-ear earphone, the socket part preferably adopts the elastic sleeve body in the ear support structure provided by the above-mentioned second embodiment, and the support part 52 preferably adopts the elastic support body in the ear support structure provided by the above-mentioned second embodiment.

[0074] To improve the connection stability between the earphone body and the socket part, preferably, when the outer surface of the earphone body is a smooth surface, the inner wall of the accommodation cavity of the socket part is also a smooth surface; when the outer surface of the earphone body is a matte surface, the inner wall of the accommodation cavity of the socket part is also a matte surface. The above setting method can increase the friction force between the earphone and the inner wall of the accommodation cavity of the socket part, thereby improving the connection stability of the socket part and the support part 52 on the earphone.

[0075] When the support part 52 is connected to the earphone body 51 through the socket part, further, a plurality of support parts 52 can be correspondingly configured for one earphone body 51, each support part 52 is respectively connected to a socket part, the structures of the socket parts are the same, and the lengths of different support parts 52 in the first direction are different. With such a setting, the user can select a support part 52 with a higher matching degree with his own ear, thereby improving the wearing stability of the earphone and the wearing comfort.

[0076] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
