AI Technical Summary
Since each person's ear canal shapes are different, users may achieve sealing effect by adjusting the wear angle of the earphones, but in fact, the ear cap and ear canal are not closely fitted, resulting in air leakage and reducing the passive noise reduction effect.
An ear cap structure including the main ear cap and the secondary ear cap is designed. The main ear cap is closely connected with the ear arthrode cavity and the tragus through the mounting column and sound guide channel to form a first-level seal, and the secondary ear cap and the ear canal opening. A tight fit is formed into a secondary seal to achieve a dual superposition passive noise shielding effect.
The passive noise reduction effect of the headphones is significantly enhanced through the dual sealing structure, and the squeezing perception of the secondary ear cap allows users to intuitively confirm the sealing state, reducing the frequent adjustment of the headphone wearing state due to concerns that the seal is not tight.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of earphones, and in particular to an ear cap and an earphone. Background Art
[0002] A key feature of headphones is their passive noise reduction function, that is, the ability to isolate external noise, which is essential for providing a high-quality listening experience. In our consumer wearing survey, we found that consumers mainly judge whether the headphones fit tightly with the ear canal by the contact feeling at the ear canal opening.
[0003] However, since each person's ear canal has a different shape, for example, the lower part of the ear canal opening of some consumers is slightly higher than the concha cavity. In this case, in order to achieve the perceived sealing effect, they may tilt the earphones downward. Although this makes them feel that the earphones are tightly fitted to the ear canal opening, in fact, the ear caps of the earphones may have wrinkles, and there is no tight fit between the ear caps and the concha cavity and tragus, resulting in air leakage, thereby reducing the passive noise reduction effect. Utility Model Content
[0004] The embodiments of the present application provide an ear cap and earphones, which can solve the technical problem that when users wear earphones based on their sense of feeling, the ear cap may not fit tightly against the ear canal, thereby reducing the passive noise reduction effect.
[0005] An embodiment of the present application provides an ear cap, which includes a main ear cap and a secondary ear cap.
[0006] The main ear cap includes a mounting post and an ear cap body. The mounting post is provided with a sound guide channel running through both ends thereof. The ear cap body is connected to the mounting post and is arranged around the outer circumference of the mounting post. The secondary ear cap is connected to the mounting post and / or the ear cap body. The secondary ear cap is provided with a sound guide hole connected to the sound guide channel.
[0007] Based on the ear cap of the embodiment of the present application, a sound guide channel running through both ends of the mounting post is provided on the mounting post, and the ear cap body is sleeved on the outer periphery of the mounting post, so that the ear cap body is wrapped around the outer periphery of the sound guide channel, and the secondary ear cap is connected to the mounting post and / or the ear cap body, and the secondary ear cap is provided with a sound guide hole connected to the sound guide channel. When the user inserts the earphone into the ear, the ear cap body can fit tightly with the concha cavity and the tragus, so that the ear cap body and the ear fit tightly together to form a primary seal, effectively sealing the sound guide channel inside the ear cap body, which can achieve the effect of passively shielding noise. At the same time, the secondary ear cap can fit tightly with the ear canal opening of the ear to form a secondary seal, which is combined with the primary seal to form a double-superimposed passive noise shielding effect, so that the sound in the earphone can be clearly transmitted to the user's ear through the sound guide channel and the sound guide hole, and the secondary ear cap is squeezed at the ear canal opening, so that the user can intuitively feel the sealing state of the ear canal opening, thereby reducing the situation of frequently adjusting the wearing state of the earphone due to concerns about loose sealing, which not only improves the user experience, but also further enhances the noise reduction effect.

[0031] In the tide of the digital age, music has become an indispensable part of people's lives. Headphones, as an important medium for music playback, have become one of the most common electronic devices in our daily lives. At the same time, ear caps, as a part of headphones, also play an important role, providing music lovers with a more comfortable and private listening experience.
[0032] Earphones have passive noise reduction function, that is, the ability to isolate external noise, which is essential to providing a high-quality auditory experience. In our consumer wearing survey, we found that consumers mainly judge whether the earphones fit tightly to the ear canal by the contact feeling at the ear canal opening.
[0033] However, since each person's ear canal has a different shape, for example, the lower part of the ear canal opening of some consumers is slightly higher than the concha cavity. In this case, in order to achieve the perceived sealing effect, they may tilt the earphones downward. Although this makes them feel that the earphones are tightly fitted to the ear canal opening, in fact, the ear caps of the earphones may have wrinkles, and there is no tight fit between the ear caps and the concha cavity and tragus, resulting in air leakage, thereby reducing the passive noise reduction effect.
[0034] To solve the above problems, the present application proposes an earphone. In an embodiment of the present application, the earphone includes an earphone body and an ear cap 100. The earphone body has a sound mouthpiece, which is located at the front end of the earphone and is responsible for directing the sound directly to the user's ear. The ear cap 100 is detachably connected to the sound mouthpiece.
[0035] When the user wears the earphone on the ear 2, the ear cap 100 can fit tightly against the user's ear 2, and the ear cap 100 can form a relatively closed space with the ear 2, so that the ear cap 100 can ensure a good seal between the sound mouthpiece and the ear 2, reduce sound leakage, thereby enhancing the immersiveness of the sound effect, and reduce the interference of external noise. This is especially important for users who listen to music or make calls in a noisy environment, and can provide better sound immersion and call clarity.
[0036] At the same time, the ear cap 100 in the present application can also be squeezed at the ear canal opening 23, so that the user can intuitively feel the sealing state of the ear canal opening 23. Therefore, when the user wears the earphones, the user can reduce the frequent adjustment of the earphone wearing state due to concerns about loose sealing, which not only improves the user experience, but also further enhances the noise reduction effect.
[0037] See also Figure 1 and Figure 2 As shown, an ear cap 100 proposed in the present application is shown. In an embodiment of the present application, the ear cap 100 includes a main ear cap 1 and a secondary ear cap 3 .
[0038] The main ear cap 1 includes a mounting post 11 and an ear cap body 12. The mounting post 11 is a cylindrical structure as a whole and is used for mounting a sound mouthpiece. The mounting post 11 is provided with a sound guide channel 111 running through both ends thereof, and the sound guide channel 111 is used to transmit the sound generated by the sound mouthpiece to the user's ear canal. In some embodiments, the central axis of the sound guide channel 111 is collinear with the central axis of the mounting post 11. In some other embodiments, the central axis of the sound guide channel 111 may be parallel to the central axis of the mounting post 11 but not collinear, or the central axis of the sound guide channel 111 may be inclined to each other with the central axis of the mounting post 11. Along the extension direction of the sound guide channel 111, the outer diameter of the mounting post 11 gradually increases or decreases, so that a plurality of protruding rings are formed on the outer peripheral wall of the mounting post 11. The plurality of protruding rings may increase the structural strength of the mounting post 11.
[0039] The shape of the ear cap body 12 is a horn-like structure, so that the ear cap body 12 has two openings, one large and one small. In this embodiment, the end of the ear cap body 12 with the smaller opening can be connected to the mounting post 11, and the ear cap body 12 is arranged around the outer periphery of the mounting post 11, so that the ear cap body 12 can be wrapped around the outer periphery of the sound guide channel 111, thereby reducing sound leakage in the sound guide channel 111.
[0040] Combination Figures 4 to 6 As shown, the secondary ear cap 3 can be connected to the mounting post 11 or the ear cap body 12, and combined with Figures 7 to 9As shown, the secondary ear cap 3, the mounting post 11 and the ear cap body 12 may be connected together. Specifically, along the extension direction of the sound guide channel 111, the secondary ear cap 3 may be arranged at one end of the mounting post 11, and the ear cap body 12 is connected near the connection between the secondary ear cap 3 and the mounting post 11, and the end of the ear cap body 12 with a larger opening is arranged in a direction away from the secondary ear cap 3, wherein the secondary ear cap 3 is provided with a sound guide hole 301, and the sound guide hole 301 is communicated with one end of the sound guide channel 111. Figure 1 The N axis in FIG. 3 represents the central axis of the sound guide hole 301, and Figure 1 The Z axis in FIG. 1 is the central axis of the sound guide channel 111 .
[0041] Combination Figure 3 The figure shows a schematic diagram of a human ear 2. The ear 2 includes a concha cavity 21, a tragus 22 and an external auditory canal. When a user inserts an earphone into the ear 2, the ear Figure 1 and Figure 2 As shown, the outer wall of the ear cap body 12 can fit tightly with the concha cavity 21 and the tragus 22, so that the ear cap body 12 fits tightly in the ear 2 and forms a primary seal, which can effectively seal the sound guide channel 111 in the ear 2, and can play a passive noise shielding effect. At the same time, the secondary ear cap 3 can be inserted into the ear canal opening 23 of the external auditory canal, and the secondary ear cap 3 can fit tightly with the ear canal opening 23 after being compressed to form a secondary seal. The combination of the primary seal and the secondary seal can form a double-superimposed passive noise shielding effect, so that the sound in the earphone can be more clearly transmitted to the user's ear through the sound guide channel 111 and the sound guide hole 301, and the secondary ear cap 3 can be squeezed at the ear canal opening 23, so that the user can intuitively feel the sealing state of the ear canal opening 23, thereby reducing the situation of frequently adjusting the wearing state of the earphone due to concerns about loose sealing, which not only improves the user experience, but also further enhances the noise reduction effect.
[0042] See also Figures 7 to 9 As shown, in some embodiments, the secondary ear cap 3 may include a sealing portion 32, which defines a sound guide hole 301, and the sealing portion 32 is connected to the mounting post 11 and the ear cap body 12, so that the sound guide hole 301 can be connected to the sound guide channel 111.
[0043] Specifically, the mounting post 11 and the ear cap body 12 can be partially embedded in the sealing part 32, so that the sealing part 32 is firmly connected to the mounting post 11 and the ear cap body 12 to prevent sound leakage at the connection point between the sound guide hole 301 and the sound guide channel 111; when the user wears the earphone, the sealing part 32 can be inserted into the ear 2 and seal the ear canal opening 23 to further enhance the noise reduction effect.
[0044] See also Figure 4 and Figure 5As shown, in some embodiments, the shape of the ear cap body 12 can be round or oval, so that the ear cap 100 has two small categories of round and oval shapes, which can increase the diversity of categories and facilitate users to choose the ear cap 100 that suits them.
[0045] Combination Figure 6 As shown, the secondary ear cap 3 may include an elastic connecting portion 31 and a sealing portion 32. The shape of the elastic connecting portion 31 is generally a cylindrical structure. A partial sound guide hole 301 is formed in the elastic connecting portion 31. One end of the elastic connecting portion 31 may be connected to the mounting post 11, or one end of the elastic connecting portion 31 is connected to the ear cap body 12, or one end of the elastic connecting portion 31 is connected to the mounting post 11 and the ear cap body 12 together, so that the partial sound guide hole 301 located on the elastic connecting portion 31 can be connected to the sound guide channel 111.
[0046] The sealing part 32 is a cylindrical structure, and another part of the sound guide hole 301 is formed on the sealing part 32. The sealing part 32 is connected to one end of the elastic connecting part 31 away from the mounting column 11. The sealing part 32 can be connected to the elastic connecting part 31 as a whole or separately, so that the sealing part 32 and the elastic connecting part 31 can constitute a complete sound guide hole 301. Preferably, the central axis of the sound guide hole 301 is coaxially arranged with the central axis of the sealing part 32 and the central axis of the elastic connecting part 31.
[0047] When the secondary ear cap 3 is inserted into the ear 2, the sealing portion 32 is used to contact the ear canal opening 23, and the sealing portion 32 will be compressed, so that the sealing portion 32 and the ear canal opening 23 are tightly fitted, and in this process, the elastic connecting portion 31 will drive the sealing portion 32 to deflect, so that the sound guide hole 301 located in the sealing portion 32 can be connected with the ear canal opening 23, so that the sound can be transmitted to the user more clearly, and the sealing portion 32 can also be squeezed at the ear canal opening 23 more accurately, so that the user can feel the sealing state of the ear canal opening 23 more intuitively.
[0048] See also Figure 6 As shown, in some embodiments, along the extension direction of the sound guide channel 111, the thickness of the sealing portion 32 is S, wherein S is less than or equal to 20 mm, so that the thickness of the sealing portion 32 is not too thick. If the thickness of the sealing portion 32 is greater than 20 mm, inserting the ear cap 100 into the ear 2 may completely block the ear canal opening 23, causing the user to be unable to clearly hear the sound of the earphone. The sealing portion 32 may also be over-compressed, causing the sound guide hole 301 to be blocked, which also causes the user to be unable to clearly hear the sound of the earphone, and also increases the user's discomfort, resulting in reduced comfort for the user wearing the earphone.
[0049] In some embodiments, the compression ratio of the sealing portion 32 is between 10% and 100%, so that when the sealing portion 32 contacts the ear canal opening 23, the sealing portion 32 is more easily compressed into a shape that matches the ear canal opening 23. Moreover, since the internal contour structure of each person's ear is different, a softer sealing portion 32 can increase the adaptation range of the ear cap 100 and increase the wearing comfort of the user.
[0050] See also Figure 6 As shown, in some embodiments, the sealing portion 32 can be made of sponge, so that the sealing portion 32 has a soft characteristic and is easier to be compressed. The sponge is a porous material, which can be beneficial to the transmission of sound, so that the sound in the earphone can be transmitted to the user's ears more clearly.
[0051] The elastic connection part 31 can be made of silicone. The strong plasticity of silicone makes the elastic connection part 31 have good elasticity. Therefore, when the secondary ear cap 3 is inserted into the ear 2, the elastic connection part 31 can support and squeeze the sealing part 32 while the elastic connection part 31 can also undergo a certain deflection, driving the sealing part 32 to move a certain distance, so that the sound guide hole 301 can be connected with the ear canal opening 23.
[0052] See also Figures 10 to 15 As shown, in some other embodiments, the sealing part 32 and the elastic connecting part 31 are made of the same material, so that the sealing part 32 and the elastic connecting part 31 can form an integrated structure. For example, the sealing part 32 and the elastic connecting part 31 are both made of silicone, or the sealing part 32 and the elastic connecting part 31 are both made of sponge, which can facilitate the manufacture of the secondary ear cap 3.
[0053] See also Figure 6 As shown, in some embodiments, specifically, when the ear cap 100 is not deformed, along a direction perpendicular to the central axis of the sound guide channel 111, the maximum outer diameter of the ear cap body 12 is L, and the maximum outer diameter of the sealing portion 32 is D, wherein the difference between L and D is greater than or equal to -15 mm, and less than or equal to 15 mm. Within this difference range, it can be ensured that the size of the ear cap 100 can fit the ears of most people, thereby avoiding the situation where the ear cap 100 may be unstable when worn due to excessive difference in size between the ear cap body 12 and the sealing portion 32.
[0054] To be more clear, if the maximum outer diameter L of the ear cap body 12 is 20 mm larger than the maximum outer diameter D of the sealing portion 32, when the ear cap body 12 fits tightly against the concha cavity 21 and the tragus 22, the size of the sealing portion 32 may be smaller than the size of the ear canal opening 23, resulting in the sealing portion 32 being unable to fit tightly against the ear canal opening 23, thereby the sealing portion 32 being unable to form a secondary seal with the ear canal opening 23, making the ear cap 100 unstable to wear.
[0055] Similarly, if the maximum outer diameter L of the ear cap body 12 is 20 mm smaller than the maximum outer diameter D of the sealing portion 32, when the sealing portion 32 is tightly fitted with the ear canal opening 23, the size of the ear cap body 12 may be smaller than the size of the concha cavity 21, resulting in the ear cap body 12 being unable to fit tightly with the concha cavity 21 and the tragus 22, and the ear cap body 12 being unable to form a secondary seal with the concha cavity 21 and the tragus 22, making the ear cap 100 unstable to wear.
[0056] See also Figures 4 to 6 As shown, in some embodiments, the elastic connecting portion 31 may include a connecting column 311 and a connecting skirt 312, the connecting column 311 may be a straight cylindrical structure, and the inner wall surface of the connecting column 311 may define a sound guide hole 301, one end of the connecting column 311 may be connected to the mounting column 11 and / or the ear cap body 12, so that the sound guide hole 301 is connected to the sound guide channel 111, and a connecting skirt 312 is provided on the outer edge of the other end of the connecting column 311, that is, the connecting skirt 312 protrudes and extends from the outer wall surface of the connecting column 311 toward the outside, so that the connecting skirt 312 can form a platform-like structure, and the sealing portion 32 is connected to the connecting skirt 312, and the connecting skirt 312 can increase the connection area between the sealing portion 32 and the connecting column 311, so that the sealing portion 32 is more firmly connected to the elastic connecting portion 31.
[0057] See also Figures 10 to 12 As shown, in some embodiments, the elastic connection part 31 is a straight cylindrical structure, and the two ends of the elastic connection part 31 are respectively connected to the mounting column 11 and the sealing part 32, so that the elastic connection part 31 can play a role in supporting the sealing part 32, and the elastic connection part 31 has a simple structure and is easy to process.
[0058] Or, combined Figures 12 to 15 As shown, the elastic connecting portion 31 may include at least two connecting segments 313, and the at least two connecting segments 313 are connected in sequence, and along the extension direction of the sound guide channel 111, the outer diameters of the two connecting segments 313 may increase or decrease, and the outer diameter change trends of two adjacent connecting segments 313 are opposite.
[0059] To be more clear, in two adjacent connecting segments 313, along the extension direction of the sound guide channel 111, for example, along the direction close to the secondary ear cap 3, if the outer diameter of one connecting segment 313 increases, the outer diameter of the other connecting segment 313 decreases and becomes larger, so that the side walls of the two adjacent connecting segments 313 intersect at an angle, which can facilitate the compression of the elastic connecting part 31.
[0060] Preferably, combined Fig.15As shown, the side walls of two adjacent connecting sections 313 intersect to form an angle β, and the open end of the angle β is arranged toward the central axis of the elastic connecting part 31, so that when the elastic connecting part 31 is compressed, the outer diameter of the two adjacent connecting sections 313 will increase, so that the radial size of the sound guide hole 301 formed by the two connecting sections 313 will increase, so that the sound guide hole 301 located on the elastic connecting part 31 can better transmit sound.
[0061] Combination Fig.12 and Fig.15 As shown, in some embodiments, the sealing portion 32 can be bent toward the side where the elastic connecting portion 31 is located, so that the side of the sealing portion 32 away from the elastic connecting portion 31 is a curved surface structure. When the sealing portion 32 is used to contact the ear canal opening 23, the sealing portion 32 can better make adaptive deformation, so that the shape of the deformed sealing portion 32 is more adapted to the contour of the ear canal opening 23, which can increase the wearing comfort of the user.
[0062] See also Figure 1 and Figure 2 As shown, in some embodiments, when the ear cap 100 is inserted into the ear 2, the secondary ear cap 3 will first contact the ear canal opening 23, and as the ear cap 100 gradually extends into the ear 2, the secondary ear cap 3 will be gradually squeezed, so that the secondary ear cap 3 will be deflected relative to the mounting post 11, or it can be said that the central axis of the sound guide hole 301 is deflected relative to the central axis of the sound guide channel 111, so that the central axis of the sound guide hole 301 will intersect with the central axis of the sound guide channel 111 to form an angle α, wherein the value range of the angle α is greater than or equal to 0° and less than or equal to 90°, so that the sound guide hole 301 can be deflected to communicate with the ear canal opening 23, and can adapt to the shape of the ear 2 of most people, thereby increasing the wearing comfort of the ear cap 100.
[0063] In some embodiments, when the ear cap 100 is inserted into the ear 2, the secondary ear cap 3 can be offset relative to the mounting post 11, and the offset of the secondary ear cap 3 is less than or equal to 30 mm. Similarly, the sound guide hole 301 can be offset to communicate with the ear canal opening 23, so that the ear cap 100 can adapt to the shape of the ear 2 of different people.
[0064] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
