[0045] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as that generally understood by those skilled in the art to which the present application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have meanings consistent with those in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as such.

[0046] The present application provides an open wearable earphone with a horn-shaped guiding structure, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 9 , which comprises an earphone shell 1, an acoustic outlet 2 (as shown in Figure 3 and Figure 9(as shown) and guide structure 3; the earphone shell 1 has a receiving cavity 101 for accommodating the speaker (as shown) and guide structure 3; Figure 3 (As shown); the sound outlet 2 is located on the front side of the earphone shell 1 and communicates with the receiving cavity 101; one end of the guide structure 3 is detachably connected to the earphone shell 1 from the sound outlet 2, and the other end of the guide extends outward; the guide structure 3 is horn-shaped and is arranged around the periphery of the sound outlet 2 to form a closed loop; the diameter of the guide structure 3 near the earphone shell 1 is smaller than the diameter of the end away from the earphone shell 1.

[0047] Specifically, without the guiding structure 3, sound released into the air through the sound outlet 2 usually diffuses in all directions, causing audio leakage. In this application, a guiding structure 3 is added to the earphone shell 1. The guiding structure 3 is directly connected to the sound outlet 2 of the earphone shell 1 and is detachable. The guiding structure 3 is used to guide the direction of sound propagation, so that the sound propagating at the sound outlet 2 is more effectively guided to a specific direction, rather than freely diffused to the outside of the earphone, thus reducing the phenomenon of audio leakage.

[0048] Furthermore, the guide structure 3 adopts a horn-shaped closed-loop structure and is arranged around the periphery of the sound outlet 2. Both ends of the horn-shaped guide structure 3 have openings along the axial direction. The opening at the end of the guide structure 3 closer to the earphone shell 1 is smaller than the opening at the end farther from the earphone shell 1, forming a gradually expanding guide surface. The small opening near the earphone shell 1 restricts excessive audio diffusion; the sound emitted from the sound outlet 2 is initially concentrated in a small area. As the guide structure 3 gradually expands, a gradually expanding propagation path is formed, allowing the sound to propagate outwards gradually, evenly, and orderly. The sound propagation is more precisely guided to the vicinity of the wearer's ear, avoiding disordered sound diffusion in the air and interference from direct interaction with airborne noise, thus significantly reducing sound leakage.

[0049] Therefore, this application adds a horn-shaped guide structure 3 around the sound outlet 2 to guide the direction of sound propagation, preventing the sound from spreading directly into the surrounding environment after being emitted from the sound outlet 2. Instead, it concentrates the sound emitted by the speaker near the sound outlet 2 and then guides it outward, avoiding excessive sound diffusion, limiting the range of audio dispersion, and allowing the audio to propagate within a more controlled range. This improves the soundproofing effect of the headphones and reduces the sound leakage that is common in open-back headphones.

[0050] In one embodiment of this application, the guide structure 3 is arranged coaxially with the sound outlet 2, and the guide structure 3 can be a circular guide structure or an elliptical guide structure.

[0051] One embodiment of this application, such as Figure 6As shown, the guide structure 3 comprises a converging section 31, a horizontal section 32 and a diverging section 33; the converging section 31 is attached to the earphone shell 1, and the diameter of the end of the converging section 31 away from the earphone shell 1 is smaller than the diameter of the sound hole 2; the inner wall of the converging section 31 is provided with a sound absorption layer; one end of the horizontal section 32 is connected to the end of the converging section 31 away from the earphone shell 1; the diverging section 33 is provided at the end of the horizontal section 32 away from the converging section 31; the diameter of the diverging section 33 gradually increases in the direction away from the horizontal section 32.

[0052] Specifically, the converging section 31 gradually reduces in diameter in the axial direction away from the earphone shell 1, and the propagation range of sound when it first leaves the earphone shell 1 is contracted by the converging section 31, producing the effect of "sound focusing", and the transmission of sound is more concentrated, avoiding immediate outward dispersion of sound. The inner wall of the converging section 31 is provided with a sound absorption layer (such as an acoustic mesh or sound-absorbing cotton), which can produce a strong absorption effect on medium and high frequencies (especially frequencies above 500 Hz), reducing the excessive amplification of these frequencies inside the earphone; the sound absorption layer absorbs the energy of these frequency bands, avoiding excessive high-frequency noise or sharp resonance peaks, thereby improving the sound quality in terms of clarity and naturalness. For low-frequency sound, the sound absorption effect is less, which makes the low-frequency part more prominent, and by suppressing unnecessary resonance peaks (such as the "head-banging" phenomenon), the frequency response curve is smoother and more natural, avoiding distortion or deficiency of low frequencies.

[0053] As can be seen, the converging section 31, through its shape structure and the damping effect of the sound absorption layer, moderately suppresses medium and high frequencies, relatively enhances the performance of low frequencies, and at the same time reduces resonance peaks, improving the naturalness of the sound and the balance of the sound quality.

[0054] The horizontal section 32, through its fixed cross-sectional area and length, affects the transition process of sound from the front side of the earphone shell 1 to the ear canal; when sound energy is transmitted from the converging section 31 to the horizontal section 32, the fixed cross-sectional area will maintain a relatively stable impedance, allowing low-frequency energy to be more evenly transmitted to the subsequent diverging section 33, without energy loss or unnecessary reflection due to impedance mismatch. The horizontal section 32 is used to provide a uniform propagation path, reducing mutual interference between different frequency bands and avoiding sudden changes in frequency response, making the sound transition process more natural and smooth; and the horizontal section 32 works together with the upstream converging section 31 and the downstream diverging section 33 to form a composite resonance system, concentrating energy in the target frequency band.

[0055] The gradually expanding section 33 has a gradually increasing diameter, which helps to make the coupling of sound and ear canal more closely, improve the transmission efficiency of sound, improve the coupling efficiency of earphone and ear canal, so that the low frequency energy which is carefully adjusted by the front cavity and damping of the earphone shell 1 can enter the ear canal more effectively instead of being reflected back at the outlet and wasted, thereby improving the sound quality performance. At the same time, the design of the gradually expanding section 33 makes the propagation direction of sound (especially in the range of medium and high frequency) more accurate, providing higher sound concentration and clarity.

[0056] It can be seen that the horn-shaped guide structure 3 in the present application adopts a three-section design, which not only effectively reduces the leakage of sound, but also improves the sound quality performance of the earphone in terms of low frequency and audio coupling efficiency, thereby providing the wearer with a more clear and natural audio experience.

[0057] In an embodiment of the present embodiment, the converging section 31, the horizontal section 32 and the gradually expanding section 33 are integrally formed.

[0058] Specifically, the converging section 31, the horizontal section 32 and the gradually expanding section 33 are arranged in sequence and integrally formed, thereby improving the overall structural strength and stability of the guide structure 3. At the same time, through integral forming, the converging section 31, the horizontal section 32 and the gradually expanding section 33 can be precisely matched to ensure smooth transition and transmission of sound energy; there is no excessive gap between the three sections, which avoids unnecessary loss of sound in the transition process, thereby improving the overall sound quality.

[0059] At the same time, integral forming can reduce the splicing of multiple parts and reduce the assembly process.

[0060] In the present application, the open wearable earphone with a horn-shaped guide structure further comprises a connecting structure arranged on the earphone shell 1 and the guide structure 3 respectively to detachably connect the guide structure 3 and the earphone shell 1.

[0061] Specifically, the guide structure 3 with different diameters will affect the propagation direction, frequency response and transmission efficiency of sound. By using the connecting structure to detachably connect the earphone shell 1 and the guide structure 3, the guide structure 3 can form a modular design, so that different specifications of the guide structure 3 (such as different materials and different sizes) can be replaced, thereby providing users with a variety of personalized customized earphones.

[0062] At the same time, after long-term use of the earphone, the guide structure 3 may accumulate dust, earwax or other pollutants; by using the connecting structure to detachably connect the earphone shell 1 and the guide structure 3, the user can easily detach the guide structure 3 for cleaning, avoiding incomplete cleaning or damaging other parts due to overall cleaning of the earphone.

[0063] In an embodiment of the present application, the guide structure 3 is a hard guide structure made of hard material to ensure the stability of the guide structure 3 in guiding the sound propagation and avoid the adverse effect on the sound guidance caused by the structural deformation of the guide structure 3 during wearing.

[0064] Embodiment one of the present application

[0065] The connecting structure includes a plug-in part 4 (as shown in Figure 4 and Figure 7 ) and an elastic expansion unit 5 (as shown in Figure 4 and Figure 5 ); the plug-in part 4 is arranged on the guide structure 3 and extends horizontally; the elastic expansion unit 5 is arranged on the earphone shell 1 and located at the periphery of the sound outlet hole 2; the elastic expansion unit 5 can expand or contract along the radial direction of the sound outlet hole 2 to hold or release the plug-in part 4.

[0066] Specifically, the plug-in part 4 is arranged at one end of the contraction section 31 away from the horizontal section 32 and extends horizontally; the elastic expansion unit 5 is arranged on the earphone shell 1 and located at the periphery of the sound outlet hole 2, so that after the plug-in part 4 is installed in cooperation with the elastic expansion unit 5, the sound outlet hole 2 can be located within the closed loop structure formed by the guide structure 3, ensuring that the sound emitted by the sound outlet hole 2 can be completely guided by the guide structure 3, and reducing the leakage of sound between the guide structure 3 and the earphone shell 1.

[0067] In the present embodiment, the earphone shell 1 is provided with a plug-in groove 11 and an expansion groove 12 (as shown in Figure 4 and Figure 5 ) at the periphery of the sound outlet hole 2; the plug-in groove 11 extends along the axial direction; the expansion grooves 12 are distributed on the inner side of the plug-in groove 11 and communicate with the plug-in groove 11; the plug-in groove 11 is used to accommodate the plug-in part 4; the elastic expansion unit 5 is arranged in the expansion groove 12 and can extend into the plug-in groove 11 to hold the plug-in part 4, and can also retract into the expansion groove 12 to release the plug-in part 4.

[0068] In an embodiment of the present application, the plug-in part 4 extends along the axial direction, and there is at least one group of plug-in parts 4; one group of plug-in parts 4 includes two plug-in parts 4, and the two plug-in parts 4 in each group are arranged symmetrically along the radial direction; correspondingly, there are multiple groups of plug-in grooves 11, each group of plug-in grooves 11 includes two plug-in grooves 11 arranged symmetrically along the radial direction, and one plug-in groove 11 accommodates one plug-in part 4. In the present embodiment, the multiple plug-in grooves 11 are arranged in sequence along the circumferential direction of the periphery of the sound outlet hole 2, the plug-in part 4 and the plug-in groove 11 both extend along the axial direction, the expansion groove 12 extends along the radial direction, and the number of expansion grooves 12 is equal to and corresponds to the number of plug-in grooves 11.

[0069] Each telescopic groove 12 contains a corresponding elastic telescopic unit 5. When the guide structure 3 is not assembled with the earphone shell 1, the free end of the elastic telescopic unit 5 extends into the insertion groove 11. When installing the guide structure 3, the insertion part 4 is aligned with the insertion groove 11 and inserted into the corresponding insertion groove 11. Under the pressure of the insertion part 4, the elastic telescopic unit 5 is squeezed and retracted into the telescopic groove 12, thereby making way for the insertion part 4, until the insertion part 4 contacts the bottom of the insertion groove 11, thus completing the installation of the guide structure 3 on the earphone shell 1.

[0070] In this embodiment, when the insertion part 4 contacts the bottom of the insertion groove 11, the free end of the elastic telescopic unit 5 also contacts the insertion part 4, and the elastic telescopic unit 5 is in a compressed state. Thus, the holding action of the elastic telescopic unit 5 on the insertion part 4 ensures the stability of the insertion part 4's positioning within the insertion groove 11. When it is necessary to disassemble the guide structure 3, simply hold the guide structure 3 and pull it outwards to disassemble the insertion part 4 from the insertion groove 11, completing the disassembly of the guide structure 3.

[0071] In this embodiment, in the second implementation, the insertion part 4 is annular and arranged around the periphery of the sound outlet 2 to form a closed-loop structure; correspondingly, the insertion slot 11 is also annular (e.g., Figure 9 (As shown). The telescopic grooves 12 are in at least one set, with each set consisting of two telescopic grooves 12 arranged symmetrically in the radial direction. Each telescopic groove 12 contains a corresponding elastic telescopic unit 5. When the guide structure 3 is not assembled with the earphone shell 1, the free end of the elastic telescopic unit 5 extends into the insertion groove 11. When installing the guide structure 3, align the insertion part 4 with the insertion groove 11 and insert it into the corresponding groove. Under the pressure of the insertion part 4, the elastic telescopic unit 5 is squeezed and retracted into the telescopic groove 12, thus making way for the insertion part 4 until the insertion part 4 contacts the bottom of the insertion groove 11, completing the installation of the guide structure 3 on the earphone shell 1. When it is necessary to disassemble the guide structure 3, simply hold the guide structure 3 and pull it outwards to disengage the insertion part 4 from the insertion groove 11, completing the disassembly of the guide structure 3.

[0072] Based on the above implementation method one or implementation method two, such as Figure 4 and Figure 5 As shown, the elastic telescopic unit 5 includes an elastic element 51 and an interference element 52; the elastic element 51 is located in the telescopic groove 12 and extends radially; one end of the elastic element 51 is connected to the bottom of the telescopic groove 12; the interference element 52 is connected to the other end of the elastic element 51 so as to reciprocate radially under the drive of the elastic element 51; the insertion groove 11 is located on the movement path of the interference element 52; when the interference element 52 extends into the insertion groove 11 and abuts against the insertion part 4, the elastic element 51 is in a compressed state.

[0073] Specifically, one end of the elastic member 51 is connected with the bottom of the telescopic groove 12, and the other end of the elastic member 51 is connected with the interference member 52, so that when the elastic member 51 is elastically deformed, the interference member 52 is moved along the radial direction; the interference member 52 can be moved into the insertion groove 11 or the telescopic groove 12 along with the elastic member 51.

[0074] When the guide structure 3 is not installed on the earphone shell 1, the elastic member 51 supports the interference member 52, and at least a part of the interference member 52 is located in the insertion groove 11; when the guide structure 3 is installed, the insertion part 4 is aligned with the insertion groove 11 and inserted into the insertion groove 11, the insertion part 4 first contacts and presses the interference member 52, the elastic member 51 is compressed, the interference member 52 is gradually moved into the telescopic groove 12 and gives way to the insertion part 4, until the insertion part 4 contacts the bottom of the insertion groove 11, then the end of the interference member 52 away from the elastic member 51 contacts the insertion part 4 and supports the insertion part 4 outward along the radial direction, so as to position the insertion part 4 in the insertion groove 11, and realize the installation of the guide structure 3 on the earphone shell 1.

[0075] If the interference member 52 extends into the insertion groove 11 and contacts the inner wall of the insertion groove 11 when the guide structure 3 is not installed, it is not easy to install the insertion part 4; therefore, a limiting part 521 is arranged around the interference member 52 in the present application, and the end face of the end of the interference member 52 away from the elastic member 51 (i.e. the head of the interference member 52) is arc-shaped; when the limiting part 521 contacts the inner wall of the end of the telescopic groove 12 close to the insertion groove 11, the head of the interference member 52 is located in the insertion groove 11 and has a gap with the insertion groove 11, so as to provide an insertion channel for the insertion part 4, and facilitate the insertion part 4 to press the interference member 52 and insert into the insertion groove 11.

[0076] Based on the first or second embodiment in the present application, the end of the insertion part 4 away from the guide structure 3 is provided with an inclined part 41 (as shown in Figure 7 , and the insertion part 4 is also provided with an arc-shaped groove 42 (as shown in Figure 7 ); the inclined part 41 is inclined from outside to inside towards the center axis, and is used to contact the interference member 52, so as to guide the insertion and installation of the insertion part 4 into the insertion groove 11; the arc-shaped groove 42 is used to accommodate the head of the interference member 52. When the insertion part 4 contacts the bottom of the insertion groove 11, a part of the head of the interference member 52 is located in the arc-shaped groove 42, so as to realize the positioning of the insertion part 4 in the insertion groove 11. The guide structure 3 is pulled outward with force, so that the interference member 52 is separated from the arc-shaped groove 42, until the insertion part 4 moves out of the insertion groove 11, so as to realize the disassembly of the guide structure 3.

[0077] The second embodiment in the present application

[0078] The earphone shell 1 is provided with a plug-in slot 11 along the periphery of the sound hole 2; the connecting structure comprises a plug-in part 4, a first magnetic part 6 and a second magnetic part 7 (as shown in Figure 8 The plug-in part 4 is arranged on the guide structure 3 and extends horizontally; the first magnetic part 6 is arranged on the plug-in part 4; and the second magnetic part 7 is arranged in the plug-in slot 11 and used for being magnetically attracted to the first magnetic part 6.

[0079] Specifically, the plug-in part 4 can be annular and in a closed loop structure, and the plug-in part 4 can also be multiple and arranged in pairs along the circumferential direction of the periphery of the sound hole 2. The plug-in slot 11 corresponds to the plug-in part 4, and if the plug-in part 4 is annular, the plug-in slot 11 is also annular; if the plug-in part 4 is multiple, the plug-in slot 11 is also multiple and spaced from each other.

[0080] The first magnetic part 6 is arranged on the plug-in part 4, and the second magnetic part 7 is arranged in the plug-in slot 11, so that the plug-in part 4 is positioned in the plug-in slot 11 through the magnetic attraction between the first magnetic part 6 and the second magnetic part 7, thereby achieving the installation of the guide structure 3 on the earphone shell 1. By pulling the guide structure 3 outward with force, the first magnetic part 6 and the second magnetic part 7 can be separated, thereby achieving the disassembly of the guide structure 3.

[0081] Based on the first or second embodiment, the plug-in part 4 and the guide structure 3 are integrally formed, so as to ensure the connection strength and structural stability between the plug-in part 4 and the guide structure 3.

[0082] In an embodiment of the present application, as shown in Figure 1 、 Figure 2 、 Figure 6 and Figure 9 , the open wearable earphone with the horn-shaped guide structure further comprises a flexible sleeve 8, which is sleeved on the guide structure 3 away from the earphone shell 1.

[0083] Specifically, since the diameter of the gradually expanding section 33 away from the earphone shell 1 is the largest, it is closer to the ear canal and more likely to contact the skin of the user's ear, therefore, in this embodiment, the flexible sleeve 8 is sleeved on the gradually expanding section 33 of the guide structure 3, so as to avoid the direct contact of the gradually expanding section 33 with the skin of the human ear, and the flexible sleeve 8 is used to contact the skin of the human ear, thereby enhancing the comfort of wearing.
