[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] Clip-on earphones are worn on the outer ear, without needing to be inserted into or hooked onto the ear. Compared to semi-in-ear earphones that fit snugly at the entrance of the ear canal, clip-on earphones offer a more open, breathable, and comfortable fit, as well as better stability during exercise. However, the sound-generating module (i.e., the speaker unit) of clip-on earphones is usually some distance from the ear canal, resulting in less effective sound pickup compared to semi-in-ear earphones. Sound pickup quality refers to call / voice interaction quality, which can be assessed using parameters such as Speech Transmission Index (STI), Signal-to-Noise Ratio (SNR), and frequency response consistency.

[0052] Therefore, this application provides an ear-clip earphone, which includes a first shell, a second shell, and a connecting bridge. The first shell and the second shell are spaced apart to form a clamping space. The first shell houses a sound-generating module and can fit snugly against the ear canal to achieve a semi-in-ear effect, improving sound quality. The first shell can rotate around the first end of the connecting bridge, allowing adjustment of the insertion angle of the first shell, thereby improving the fit of the ear-clip earphone. The first shell near the first end has a hollow structure to provide a ventilation channel, reducing the stuffiness and heat caused by long-term wear, balancing ear pressure, and improving wearing comfort.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] See Figures 1 to 8 This application provides an ear-clip earphone, which includes a first housing 10, a second housing 20, and a connecting bridge 30. The first housing 10 houses a sound-generating module, and the second housing 20 is spaced apart from the first housing 10, forming a clamping space between the first housing 10 and the second housing 20. The connecting bridge 30 includes a first end and a second end, with the first end connected to the first housing 10 and the second end connected to the second housing 20. The first housing 10 is rotatable around the first end, and the first end of the first housing 10 has a hollow structure 11.

[0055] The first housing 10 provides space for the sound-generating module and secures it, providing support and protection and preventing it from shaking within the housing. For example, the first housing 10 is hollow to accommodate the sound-generating module. The sound-generating module can produce sound and can utilize existing structures, which will not be elaborated upon here. The first housing 10 is rotatably connected to the first end of the connecting bridge 30, and the first housing 10 rotates circumferentially relative to the connecting bridge 30 about the first end of the connecting bridge 30 as its pivot point.

[0056] The first housing 10 is provided with a plurality of sound outlets. For example, the surface of the first housing 10 facing the concha cavity has a plurality of sound outlets. The sound outlets connect the interior and exterior of the first housing 10, allowing the sound generated by the sound-generating module to be transmitted to the exterior of the first housing 10, thereby enabling the user to hear the sound and improving the sound effect. The sound outlets can be circular, elliptical, or other shapes. The plurality of sound outlets can be arranged in an array or arbitrarily.

[0057] The first shell 10 has a hollow structure 11, which can be regular or irregular holes or gaps. The hollow structure 11 can extend along the ear canal, thereby connecting the ear canal and the outside of the ear. In this way, on the one hand, it can provide a ventilation channel, reduce the stuffiness and heat caused by long-term wear, balance ear pressure, and improve wearing comfort; on the other hand, it can remove some materials to achieve weight reduction.

[0058] In some possible examples, the first housing 10 is annular, with the central hole serving as the perforated structure 11. This allows the first housing 10 to fit snugly against the ear canal entrance, forming a semi-in-ear design that is closer to the ear canal and provides better sound pickup. For example, the first housing 10 can be a circular or elliptical annular shape, with a cross-section perpendicular to the axis of the perforated structure 11. The cross-sectional shape of the perforated structure 11 can be circular, elliptical, oblong, rounded rectangle, or other shapes. The corresponding sound-emitting module can also be annular, thus adapting to the shape of the first housing 10 and improving sound uniformity.

[0059] In some possible examples, such as Figure 5 As shown, the first housing 10 includes a first part 12 and a second part 13. The first part 12 is connected to the connecting bridge 30 and has a first through hole 14. The second part 13 is connected to the first part 12 and has a second through hole 15. The second through hole 15 is opposite to the first through hole 14, forming a hollow structure 11. The sound-generating module is annular in shape. The shape of the sound-generating module refers to the fact that, with a plane perpendicular to the axis of the hollow structure 11 as the cross-section, the cross-sectional shape of the sound-generating module is annular, which can be either circular or elliptical.

[0060] The first housing 10 includes a first component 12 and a second component 13. The first component 12 and the second component 13 are separate components, which facilitates the use of different materials and shapes as needed, and also facilitates the molding and assembly of the first component 12 and the second component 13. The first component 12 and the second component 13 can also be an integrated structure. In this embodiment, the structure and material of the first component 12 and the second component 13 are not limited and can be designed as needed.

[0061] The second component 13 is located on the side of the first component 12 closest to the ear canal, and also on the side of the first component 12 furthest from the connecting bridge 30. The stacking direction of the first component 12 and the second component 13 serves as the height direction of the first housing 10, which can be parallel to the axial direction of the hollow structure 11. The first component 12 has a first through hole 14, and the second component 13 has a second through hole 15. The first through hole 14 and the second through hole 15 are connected to form the hollow structure 11. The shape of the first through hole 14 and the shape of the second through hole 15 can be the same or different.

[0062] The first component 12 and the second component 13 can be bonded, snap-fitted, fastened, or connected in other ways. For example, the surfaces of the first component 12 and the second component 13 facing each other are flat, and an adhesive is applied between these two surfaces. Figure 5 and Figure 6 As shown, the bottom surface of the first part 12 and the top surface of the second part 13 are both flat. The first part 12 is closer to the ear canal and can house a sound-generating module. The second part 13 is connected to the connecting bridge 30 and can house a motherboard, etc. The motherboard is electrically connected to the sound-generating module to control the sound-generating module.

[0063] Continue reading Figures 1 to 8 The second housing 20 is spaced apart from the first housing 10, forming a clamping space between them to accommodate and clamp the auricle. For example, Figure 6 and Figure 7 As shown, the second housing 20 and the first housing 10 are movably configured, meaning they can move relative to each other, for example, moving closer or further apart. This allows for different distances between the second housing 20 and the first housing 10, enabling the clamping space to be enlarged or deformed to suit different auricles. For example, the distance between the first housing 10 and the second housing 20 is specifically the shortest point-to-point distance between the main body 21 of the second housing 20 and the second segment of the first housing 10.

[0064] It is understandable that when the distance between the first housing 10 and the second housing 20 is at its maximum value, such as... Figure 7 As shown, the clamping space is at its maximum and greater than the thickness of the auricle. When the distance between the first housing 10 and the second housing 20 is at its minimum, as... Figure 6 As shown, the clamping space is minimal and less than the thickness of the auricle. During normal wear, the distance between the first shell 10 and the second shell 20 lies between the maximum and minimum values ​​mentioned above, matching the thickness of the auricle. The first shell 10 and the second shell 20 are located on the front and back sides of the auricle, respectively, and both reliably press against the auricle to form a good clamping force, improving wearability and stability, and preventing the auricle from falling off.

[0065] Continue reading Figures 1 to 8 The second housing 20 houses a battery, providing space for its installation, securing it, supporting and protecting it, and preventing it from shifting within the housing. For example, the second housing 20 is hollow to accommodate the battery. The battery is electrically connected to the sound-generating module, providing it with power. The battery can utilize an existing structure, which will not be elaborated upon here.

[0066] In some possible examples, such as Figure 5 and Figure 8 As shown, the second housing 20 includes a main body 21 and a tail 22. A battery or similar component is housed within the main body 21 and contacts the auricle. The tail 22 is disposed on the outer peripheral surface of the main body 21 and is connected to the connecting bridge 30. The tail 22 and the connecting bridge 30 partially overlap. A second rotating shaft 50 passes through the end of the tail 22 furthest from the main body 21 and through the connecting bridge 30, thereby enabling relative rotation between the second housing 20 and the connecting bridge 30.

[0067] The tail section 22 is arc-shaped, and the connecting bridge 30 is C-shaped. In this way, the main body 21, which is equipped with components such as batteries, and the first housing 10, which is equipped with components such as sound-generating modules, are connected by arc-shaped and C-shaped structures. This allows the movement path of the first housing 10 relative to the main body 21 to form a complex curve (such as a cycloid), which facilitates assembly and avoidance, and forms a more stable constraint.

[0068] In some possible implementations, the main body 21 includes a third part 23 and a fourth part 24 connected together. The third part 23 and the fourth part 24 are assembled to form the main body 21, for example, by gluing, snapping, or connecting with fasteners. Both the third part 23 and the fourth part 24 contact the auricle. The arrangement direction of the third part 23 and the fourth part 24 is perpendicular to the extension direction of the connecting bridge 30. Both the third part 23 and the fourth part 24 are provided with openings, for example, the third part 23 and the fourth part 24 are cylindrical. The openings of the third part 23 and the fourth part 24 are opposite and connected, forming a large space to accommodate components such as batteries.

[0069] The tail section 22 includes a fifth part 25 and a sixth part 26 connected to each other. The fifth part 25 and the sixth part 26 are assembled to form the tail section 22, for example, by bonding, snapping, or connecting with fasteners. Both the fifth part 25 and the sixth part 26 are connected to the connecting bridge 30. The fifth part 25 is disposed on the third part 23, for example, the fifth part 25 and the third part 23 can be a one-piece molded structure. The sixth part 26 is disposed on the fourth part 24, for example, the sixth part 26 and the fourth part 24 can be a one-piece molded structure.

[0070] For example, the fifth component 25 and the third component 23 are integrally molded structures, and the sixth component 26 and the fourth component 24 are integrally molded structures. In this case, the fifth component 25 and the sixth component 26 are connected, and / or the third component 23 and the fourth component 24 are connected, thereby assembling the second shell 20 into a whole.

[0071] One end of the fifth component 25 can be flush with the opening of the third component 23; for example, the surface of the fifth component 25 facing the sixth component 26 is flush with the opening of the third component 23. One end of the sixth component 26 can be flush with the opening of the fourth component 24; for example, the surface of the sixth component 26 facing the fifth component 25 is flush with the opening of the fourth component 24. In this way, the fifth component 25 and the sixth component 26 can be joined together, improving the overall strength of the tail section 22.

[0072] The fifth part 25 and the sixth part 26 are also rotatably connected to the connecting bridge 30. For example, the end of the fifth part 25 away from the third part 23 and the end of the sixth part 26 away from the fourth part 24 are both connected to the connecting bridge 30.

[0073] As one possible implementation, the end of the fifth part 25 away from the third part 23 and the end of the sixth part 26 away from the fourth part 24 both have lugs. The two lugs are located on both sides of the connecting bridge 30. The two lugs and the connecting bridge 30 are respectively provided with mounting holes 27. The rotational connection is achieved by placing the second rotating shaft 50 in the mounting holes 27.

[0074] As another possible implementation, the connecting bridge 30 has two lugs at one end adjacent to the fifth component 25 and the sixth component 26. The two lugs are located on opposite sides of the fifth component 25 and the sixth component 26, respectively. Both lugs and the connecting bridge 30 are provided with mounting holes 27, and a rotatable connection is achieved by placing the second rotating shaft 50 within the mounting holes 27. Of course, the fifth component 25, the sixth component 26, and the connecting bridge 30 can be rotatably connected in other ways, and this embodiment is not limited thereto.

[0075] To achieve adjustable clamping space between the second housing 20 and the first housing 10, the second housing 20 and the connecting bridge 30 are connected by a second rotating shaft 50. This allows the second housing 20 and the connecting bridge 30 to rotate relative to each other, enabling relative movement between them by having the connecting bridge 30 move the first housing 10 closer to or further away from the second housing 20. For example, both the second housing 20 and the connecting bridge 30 may have corresponding mounting holes 27, with the second rotating shaft 50 passing through the mounting holes 27, and both the second housing 20 and the connecting bridge 30 can rotate around the second rotating shaft 50.

[0076] In some possible implementations, one of the second housing 20 and the first end of the connecting bridge 30 is provided with a second receiving cavity, and the other is provided with a first limiting portion, with the second limiting portion disposed within the second receiving cavity; the ear clip-on earphone also includes an elastic element 40, one end of which abuts against the first limiting portion and the other end against the second limiting portion, and deforms as the first housing 10 and the second housing 20 move away from each other to provide a clamping force. Specifically, under the action of an external force, the first housing 10 and the second housing 20 move away from each other; as the first housing 10 and the second housing 20 move away from each other, the deformation of the elastic element 40 increases; after the external force is removed, the elastic element 40 causes the first housing 10 and the second housing 20 to move closer together, thereby providing a clamping force.

[0077] For example, the second housing 20 has a second receiving cavity near one end of the connecting bridge 30, the second receiving cavity facing the connecting bridge 30, and a second limiting portion is provided inside the second receiving cavity. The connecting bridge 30 has a first limiting portion near one end of the second housing 20, and the first limiting portion extends into the second receiving cavity. As another example, the connecting bridge 30 has a second receiving cavity near one end of the second housing 20, the second receiving cavity facing the second housing 20, and a second limiting portion is provided inside the second receiving cavity. The second housing 20 has a first limiting portion near one end of the connecting bridge 30, and the first limiting portion extends into the second receiving cavity.

[0078] The elastic element 40 can be a spring, such as a metal spring. The elastic element 40 is located within the second receiving cavity, with one end abutting against a first limiting portion and the other end abutting against a second limiting portion, for providing clamping force. Figure 5 and Figure 8 As shown, a second receiving cavity is provided inside the second housing 20, and a first limiting part is provided in the connecting bridge 30. Specifically, the fifth part 25 and the sixth part 26 are assembled relative to each other to form the second receiving cavity, and a second limiting part is provided inside the fifth part 25 or the sixth part 26.

[0079] In some possible examples, one of the first and second limiting portions is a second slot 28, and the other is a protrusion 32; one end of the elastic member 40 is embedded in the second slot 28, which can improve the stability of the elastic member 40. The second housing 20 (e.g., the sixth segment 26) has a second receiving cavity, and the wall of the second receiving cavity has the second slot 28, with one end of the elastic member 40 located within the second slot 28. The second slot 28 can be formed by two opposing plates, and the second slot 28 can be irregularly shaped to hold the elastic member 40 in place and prevent it from detaching. These two plates can also be connected to other walls of the second receiving cavity (e.g., the outer peripheral surface of the fifth segment 25) to limit the elastic member 40.

[0080] like Figure 8As shown, the connecting bridge 30 is provided with a protrusion 32, which is located in the second receiving cavity and abuts against the elastic member 40. The end of the elastic member 40 that abuts against the protrusion 32 can be curled into an arc shape to reduce friction against the first limiting part. The end of the protrusion 32 adjacent to the second slot 28 can also protrude outward toward the elastic member 40 to limit the corresponding end of the elastic member 40 and reduce the separation of the elastic member 40 and the protrusion 32.

[0081] In other examples, the clip-on headphones may also include a torsion spring, one end of which is connected to the second housing 20 and the other end to the connecting bridge 30. The rotational axis of the torsion spring is parallel to the axis of the second pivot 50, and the torsion spring is used to bring the first housing 10 and the second housing 20 closer together to provide a clamping force. Alternatively, the connecting bridge 30 may be an elastic structure, for example, including a shape memory alloy, such as titanium wire, to provide a clamping force so that the clip-on headphones can be worn stably.

[0082] Continue reading Figures 1 to 8 A connecting bridge 30 connects the first housing 10 and the second housing 20. The connecting bridge 30 includes a first end and a second end, which are opposite each other along the extending direction of the connecting bridge 30. The first end is connected to the first housing 10, and the first housing 10 rotates around the first end; that is, the first end is the pivot of the first housing 10, allowing adjustment of the ear-mount angle of the first housing 10, thereby improving the fit of the ear-clip headphones. The second end is connected to the second housing 20, for example, through a second pivot 50, and the angle between the second end and the second housing 20 can be changed.

[0083] The connecting bridge 30 and the first housing 10 are provided with a first receiving cavity, and the other has a first rotating shaft 31. The first rotating shaft 31 is disposed in the first receiving cavity and rotates relative to the first receiving cavity. By utilizing the cooperation of the first rotating shaft 31 and the first receiving cavity, the relative rotation of the connecting bridge 30 and the first housing 10 can be realized, and this rotation is performed around the first rotating shaft 31.

[0084] In some possible implementations, the connecting bridge 30 has a first pivot 31; the hollow structure 11 in the first housing 10 forms a first receiving cavity. Thus, as... Figure 3 and Figure 4 As shown, the hollow structure 11 can accommodate the first rotating shaft 31, which can improve space utilization while ensuring air permeability, reduce the volume of the first housing 10, and facilitate insertion into the ear. In other possible embodiments, the connecting bridge 30 forms the first receiving cavity, and the first housing 10 is correspondingly provided with the first rotating shaft 31.

[0085] For example, the connecting bridge 30 includes an arched column 33 and a first rotating shaft 31 disposed at one end of the arched column 33. The arched column 33 and the first rotating shaft 31 can be an integral structure. Taking a plane perpendicular to the extension direction of the connecting bridge 30 as a cross-section, the cross-sectional shape of the arched column 33 and the first rotating shaft 31 can be rectangular, circular, elliptical, etc. For example, the cross-sectional shape of the arched column 33 is a biconvex quadrilateral (racetrack shape), and the cross-sectional shape of the first rotating shaft 31 is circular, that is, the first rotating shaft 31 is a cylinder. Further, the connecting bridge 30 also includes a protrusion 32 (first limiting part) disposed at the other end of the arched column 33. The arched column 33, the protrusion 32, and the first rotating shaft 31 can be an integral structure.

[0086] To achieve rotation of the first rotating shaft 31, a guide groove 34 is provided on one of the inner circumferential surface of the first receiving cavity and the outer circumferential surface of the first rotating shaft 31, and a guide block 16 is provided on the other. The guide block 16 is located within the guide groove 34 and moves along the guide groove 34. The guide block 16 and the guide groove 34 are respectively provided circumferentially for the first receiving cavity and the first rotating shaft 31. By moving the guide block 16 within the guide groove 34, relative rotation between the first rotating shaft 31 and the first receiving cavity is achieved.

[0087] In some examples, the guide groove 34 is disposed on the inner peripheral surface of the first receiving cavity, and the guide block 16 is disposed on the outer peripheral surface of the first rotating shaft 31. For example, the guide block 16 is a rib disposed on the circumferential side of the first rotating shaft 31. In other examples, the guide groove 34 is disposed on the outer peripheral surface of the first rotating shaft 31, and the guide block 16 is disposed on the inner peripheral surface of the first receiving cavity. The guide groove 34 and the guide block 16 are adapted to each other and can be flexibly disposed inside the first receiving cavity and outside the first rotating shaft 31 as needed, and multiple guide grooves can be disposed.

[0088] like Figure 5 As shown, the guide block 16 is disposed on the inner circumferential surface of the first receiving cavity and extends circumferentially along the first receiving cavity; the guide groove 34 is disposed on the outer circumferential surface of the first rotating shaft 31 and extends circumferentially along the first rotating shaft 31; the two ends of the guide groove 34 are spaced apart along the extending direction of the guide groove 34. In this way, the rotation angle of the first rotating shaft 31 relative to the first receiving cavity (i.e., the first housing 10) can be limited, and when the guide block 16 abuts against the end of the guide groove 34, the first rotating shaft 31 is difficult to continue rotating.

[0089] The guide block 16 and the first housing 10 can be an integral structure or separate structures. The guide block 16 can extend circumferentially around the first receiving cavity and encircle the first receiving cavity completely, i.e., the guide block 16 is annular. The guide block 16 may not encircle the first receiving cavity completely, for example, it may encircle three-quarters of the cavity. The guide block 16 has an opening, for example, the guide block 16 is C-shaped. Taking a plane perpendicular to the extension direction of the guide block 16 as a cross-section, the cross-sectional shape of the guide block 16 can be semi-circular, semi-elliptical, trapezoidal, rectangular, rounded rectangle, etc.

[0090] The guide groove 34 can surround the first rotating shaft 31 for a full circumference, i.e., the guide groove 34 is annular. Alternatively, the guide groove 34 may not surround the first rotating shaft 31 for a full circumference, for example, it may surround half a circumference. The guide groove 34 has an opening, for example, the guide block 16 is C-shaped. The shape of the guide groove 34 is adapted to the shape of the guide block 16. Taking a plane perpendicular to the extension direction of the guide groove 34 as a cross-section, the cross-sectional shape of the guide groove 34 can be semi-circular, semi-elliptical, trapezoidal, rectangular, rounded rectangle, etc.

[0091] To install the first rotating shaft 31 into the first receiving cavity, a first retaining groove is provided on the inner circumferential surface of the first receiving cavity, extending circumferentially along the cavity. The guide block 16 is an elastic open ring, which is embedded in and protrudes from the first retaining groove. The elastic open ring can be engaged in the first retaining groove and, when the first rotating shaft 31 is installed, is subjected to a radially outward spreading force, undergoing elastic deformation, increasing its opening, and then returning to its original shape within the guide groove 34. This allows the elastic open ring to be inserted into the first retaining groove, and the first rotating shaft 31 to be installed into the first receiving cavity. Alternatively, the guide groove 34 and the guide block 16 can also use other mating methods, such as the first rotating shaft 31 being directly pressed into the first receiving cavity.

[0092] The clip-on earphone in this embodiment includes a first housing 10, a second housing 20, and a connecting bridge 30. The first housing 10 houses a sound-generating module. The second housing 20 is spaced apart from the first housing 10, forming a clamping space between them. The connecting bridge 30 includes a first end and a second end, with the first end connected to the first housing 10 and the second end connected to the second housing 20. The first housing 10 rotates around its first end, and the first end of the first housing 10 has a perforated structure 11. The perforated structure 11 provides a ventilation channel, reducing the stuffiness and heat caused by prolonged wear, balancing ear pressure, and improving wearing comfort. The first housing 10 can fit snugly against the ear canal, achieving a semi-in-ear effect and improving sound quality. It can also rotate around the connecting bridge 30 to adjust the in-ear angle of the first housing 10, thereby improving the adaptability of the clip-on earphone.
