Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In the embodiments described in this disclosure, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can refer to an electrical connection or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0051] The following combination Figures 1 to 16 The clip-on headphones described in the embodiments of this disclosure will be described in detail.

[0052] In this embodiment, the clip-on earphone may include a first housing 100, a second housing 200, and a connector 300. A first end 320 of the connector 300 is connected to the first housing 100, and a second end 330 of the connector 300 is connected to the second housing 200. In the wearing state, the first housing 100 may be located in front of the wearer's ear, and the second housing 200 may be located behind the wearer's ear. The connector 300 is used to engage with the wearer's auricle; the connector 300 may contact the wearer's auricle or have a gap with it.

[0053] In this embodiment, the connector 300 connects the first housing 100 and the second housing 200. The first housing 100, the connector 300, and the second housing 200 form a clamping space 510. A clamping gap 520 may exist between the first housing 100 and the second housing 200. When the first housing 100 and the second housing 200 are in contact, the clamping gap 520 is zero; when the first housing 100 and the second housing 200 are spaced apart, the clamping gap 520 is greater than zero. In the wearing state, the portion on the wearer's earlobe side is located in the clamping space 510, and the portion on the ear root side is located between the first housing 100 and the second housing 200. The clamping force between the clamping space 510 and the first housing 100 and the second housing 200 enables the ear clip-on headphones to be stably worn on the wearer's ear.

[0054] The shape of the connector 300 is not limited. For example, the connector 300 may be C-shaped, n-shaped, parabolic, etc. This disclosure does not limit it in this respect.

[0055] The connector 300 can be elastic, allowing the distance between the first housing 100 and the second housing 200 to be adjusted based on the elasticity of the connector 300, thereby making the ear-clip headphones easy to wear. The connector 300 can also be rigid, allowing it to maintain a specific shape, thereby improving the clamping force and wearing stability of the connector 300. The material of the connector 300 is not limited. For example, the material of the connector 300 may include shape memory alloys, polymer materials, etc.

[0056] In this embodiment of the disclosure, at least a portion of the first housing 100 may be located within the concha cavity of the wearer to reduce the distance between the first housing 100 and the wearer's ear canal, thereby improving audio performance.

[0057] The first housing 100 may or may not be elastic. For example, the first housing 100 may be a rigid structure and may not be elastic. As an example, the material of the first housing 100 may include metal, plastic, etc. Alternatively, at least a portion of the first housing 100 may be elastic. The first housing 100 may be elastic throughout. As an example, the material of the first housing 100 may include rubber, etc. The first housing 100 may also be partially elastic, with the remaining portion being a rigid structure. This disclosure does not limit this aspect.

[0058] The first housing 100 may have a sound outlet channel 140 and a pressure relief channel 150. The sound-generating assembly 410 may be installed within the first housing 100 by means of bonding, snap-fitting, welding, etc. The sound-generating assembly 410 may be a speaker or other structure capable of producing sound. The sound-generating assembly 410 may include a side with a diaphragm 411 and a side opposite to the diaphragm 411. The side with the diaphragm 411 may be located in the front cavity 101, and the side opposite to the diaphragm 411 may be located in the rear cavity 102. When the sound-generating assembly 410 is in operation, the vibration of the diaphragm 411 can generate sound in the front cavity 101, and the sound from the front cavity 101 is transmitted to the wearer's ear canal through the sound outlet channel 140. The pressure in the rear cavity 102 can be adjusted through the pressure relief channel 150 to improve the audio effect.

[0059] Example 1: The first housing 100 may include a support housing 110 and an elastic housing 120. The sound-generating assembly 410 divides the space within the support housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 is wrapped around the support housing 110; the elastic housing 120 can be used to fit with the wearer's ear, and by wrapping the elastic housing 120 around the support housing 110, the softer elastic housing 120 can contact the wearer's ear, thereby improving the wearing comfort of the clip-on headphones.

[0060] In Example 1, the hardness of the support shell 110 is greater than that of the elastic shell 120. The support shell 110 can be a rigid structure. The support shell 110 can be a hard shell, and it may not be elastic, so that the sound-generating component 410 can be protected by the support shell 110. The material of the support shell 110 may include plastic, metal, etc. The elastic shell 120 may be elastic, so that it can adaptively deform to fit the shape of the wearer's ear during wearing, thereby improving the wearing comfort and fit of the ear clip headphones. The material of the elastic shell 120 is not limited. For example, the material of the elastic shell 120 may include rubber, foam, etc.

[0061] In Example 1, the position of the elastic shell 120 covering the support shell 110 is not limited. For example, the elastic shell 120 may cover the portion of the support shell 110 facing the second shell 200; the elastic force of the elastic shell 120 can adjust the clamping force between the second shell 200 and the elastic shell 120; for example, the elastic shell 120 can increase the contact area between the elastic shell 120 and the wearer's ear through elastic deformation, thereby reducing the stress per unit area and improving wearing comfort. As another example, the elastic shell 120 may cover the area of ​​the support shell 110 that mates with the wearer's concha, thereby improving the comfort of the ear clip headphones mate with the wearer's concha.

[0062] In Example 1, the area of ​​the elastic shell 120 covering the support shell 110 is not limited. For example, the elastic shell 120 may cover one side, at least both sides, half of the outer surface, or the entire outer surface of the support shell 110. This disclosure does not limit this. As an example, the surface area of ​​the support shell 110 covered by the elastic shell 120 may be larger than the surface area of ​​the support shell 110 in its exposed state, so that during wearing or removal, most of the surface of the first shell 100 can contact the wearer's ear through the softer elastic shell 120, thereby improving the comfort of wearing and removing the ear clip headphones.

[0063] In Example 1, the elastic shell 120 may be based solely on its own elastic deformation. Of course, the elastic shell 120 may also be based on spatial deformation between itself and the supporting shell 110. This disclosure does not limit this. For example, as... Figure 3 As shown, a deformation space 130 can be defined between the elastic shell 120 and the support shell 110. Here, the elastic shell 120 can deform based on its own elasticity and also based on the deformation space 130, thereby improving the deformation capability of the elastic shell 120. In other words, it can improve the ability of the elastic shell 120 to be in different sizes when worn, and thus improve the ability of the elastic shell 120 to adapt to the ears of wearers of different sizes.

[0064] In Example 1, the connection method between the elastic shell 120 and the support shell 110 is not limited. For example, the elastic shell 120 can be wrapped around the support shell 110 by means of adhesive, snap-fit, welding, etc. The elastic shell 120 and the support shell 110 can be detachably connected or non-detachably connected. When the elastic shell 120 and the support shell 110 are detachably connected, the elastic shell 120 can be replaced in time if it is damaged, hardened, or loses its elasticity. As an example, the number of elastic shells 120 can be at least two, and one of the at least two elastic shells 120 is used for detachable connection with the support shell 110; the at least two elastic shells 120 can be identical so that if one is damaged, the other can be replaced in time; the size, material, structure, etc. of the at least two elastic shells 120 can be the same. Of course, at least two elastic shells 120 can be different, and the deformation space 130 defined between at least two elastic shells 120 and the support shell 110 can be different, so that at least two elastic shells 120 have different maximum deformation amounts. The deformation space 130 refers to the space formed by the gap between the elastic shell 120 and the support shell 110, and the maximum deformation amount refers to the maximum distance that the elastic shell 120 moves towards the support shell 110 based on the deformation space 130. Since at least two elastic shells 120 have different maximum deformation amounts, the maximum external dimensions of the first shell 100 formed by at least two elastic shells 120 can be different, thereby enabling the ear clip headphones to adapt to different ear sizes, and further improving the adaptability of the ear clip headphones.

[0065] In Example 1, the elastic shell 120 may include an opening 121, through which a portion of the supporting shell 110 can be located within the cavity defined by the elastic shell 120; in other words, the elastic shell 120 can be wrapped around the supporting shell 110 through the opening 121, thereby increasing the area of ​​the elastic shell 120 wrapped around the supporting shell 110. The opening 121 may be constricted, allowing the elastic shell 120 to be stably wrapped around the supporting shell 110 and increasing the surface area of ​​the elastic shell 120 wrapped around the supporting shell 110; no other connecting structure may be provided between the supporting shell 110 and the elastic shell 120, as the elastic shell 120 can be wrapped around the supporting shell 110 by deformation. Of course, other connecting structures may also be provided between the supporting shell 110 and the elastic shell 120 to improve connection stability. In other examples, the opening 121 may also be flared, or it may be straight.

[0066] In Example 1, such as Figure 3As shown, the support shell 110 may include a connection area 111 connected to the first end 320 of the connector 300, and an annular groove 112 formed along the outer periphery of the connection area 111; the elastic shell 120 may include an opening 121, through which the elastic shell 120 is fitted over the portion of the support shell 110 facing the second shell 200. The elastic shell 120 has an annular protrusion 124 at the opening 121, which is inserted into the annular groove 112. This arrangement allows for a detachable connection between the elastic shell 120 and the support shell 110, while also improving the connection strength between them. Here, the opening 121 may be constricted.

[0067] In Example 1, the sound outlet channel 140 and the pressure relief channel 150 can be provided only in the support shell 110, or they can be provided in both the support shell 110 and the elastic shell 120. As an example, such as Figure 3 As shown, the support shell 110 may have a first sound outlet 116; the elastic shell 120 may cover the area of ​​the support shell 110 where the first sound outlet 116 is located; the elastic shell 120 has a second sound outlet 122 corresponding to the position of the first sound outlet 116; the sound outlet channel 140 may include the first sound outlet 116 and the second sound outlet 122; the first sound outlet 116 is connected to the front cavity 101; the audio of the front cavity 101 can be transmitted to the wearer's ear canal through the first sound outlet 116 and the second sound outlet 122; in the wearing state, the area around the sound outlet channel 140 is in contact with the wearer's ear or has a small gap. By covering the area of ​​the support shell 110 where the first sound outlet 116 is located with the elastic shell 120, the area around the sound outlet channel 140 is in contact with the wearer's ear or has a small gap, which can greatly improve the wearing comfort of the ear clip headphones. As another example, the support shell 110 also has a first through hole 117 communicating with the rear cavity 102; the elastic shell 120 covers the area of ​​the support shell 110 where the first through hole 117 is located; the elastic shell 120 has a second through hole 123 corresponding to the position of the first through hole 117; the pressure relief channel 150 includes the first through hole 117 and the second through hole 123, and the pressure in the rear cavity 102 can be adjusted through the first through hole 117 and the second through hole 123. During wear, the area around the pressure relief channel 150 may come into contact with the wearer's ear. By covering the area of ​​the support shell 110 where the first through hole 117 is located with the elastic shell 120, the area around the pressure relief channel 150 comes into contact with the wearer's ear through the elastic shell 120, which greatly improves the wearing comfort and safety of the clip-on headphones.

[0068] In Example 1, when a deformation space 130 is defined between the elastic shell 120 and the supporting shell 110, the deformation space 130 can communicate with the outside through a through hole in the elastic shell 120. This allows gas in the deformation space 130 to escape to the outside after the elastic shell 120 is deformed under pressure, and outside gas to enter the deformation space 130 after the pressure is released, thus enabling rapid deformation and recovery of the elastic shell 120. In some other examples, the deformation space 130 can also communicate with the outside through a second through hole 123. The second through hole 123 can both adjust the air pressure in the rear cavity 102 and enable rapid deformation of the elastic shell 120. In other examples, the deformation space 130 can also communicate with the outside through a second sound outlet 122. The second sound outlet 122 can both transmit audio and enable rapid deformation of the elastic shell 120.

[0069] In the embodiments disclosed herein, the second housing 200 may or may not be elastic. For example, the second housing 200 may be a rigid structure and may not be elastic. As an example, the material of the second housing 200 may include metal, plastic, etc. As another example, at least a portion of the second housing 200 may be elastic. The second housing 200 may be partially elastic, with the remaining portion being a rigid structure. As an example, the material of the second housing 200 may include rubber, foam, etc.

[0070] like Figure 1 As shown, the second housing 200 may have a sound pickup hole 201, and a microphone or other structure capable of picking up sound may be provided inside the second housing 200. The second housing 200 may also have a button 440, which is used to control the ear clip headphones.

[0071] The battery 420 and circuit board 430 can be disposed within the second housing 200 or the first housing 100 by means of bonding, snap-fitting, welding, etc. This disclosure does not limit this. The battery 420 is used to power the ear-clip headphones. The circuit board 430 can house electronic components and conductive circuits. The charging component 450 can be disposed at the mounting through hole 203 of the second housing 200 or the mounting through hole 203 of the first housing 100 by means of bonding, snap-fitting, welding, etc. The charging component 450 can be strip-shaped, column-shaped, etc. The material of the charging component 450 can be conductive materials such as copper or aluminum. The circuit board 430 can be electrically connected to the sound-generating component 410, the battery 420, and the charging component 450 respectively. One end of the charging component 450 is exposed through the mounting through-hole 203, and the other end of the charging component 450 can be electrically connected to the circuit board 430 by means of bonding, soldering, snap-fitting, etc. The circuit board 430 can be electrically connected to the battery 420 through wires. When the charging component 450 is connected to a power supply, the charging component 450 can charge the battery 420 through the circuit board 430. The circuit board 430 can also be electrically connected to the sound-generating component 410 through wires, and the battery 420 can also supply power to the sound-generating component 410 through the circuit board 430.

[0072] like Figure 1 and Figure 2 As shown, the second housing 200 can have a thickness direction, a height direction, and a length direction, with the thickness direction being perpendicular to the height and length directions, respectively. The thickness direction of the second housing 200 can be the direction in which the second housing 200 approaches or recedes from the first housing 100. Here, the clamping gap 520 between the second housing 200 and the first housing 100 in the thickness direction of the second housing 200 can be used to accommodate the wearer's ear, and the clamping gap 520 between the second housing 200 and the first housing 100 can be adjusted by the deformation of the connector 300. For example, the thickness direction of the second housing 200 can also be the axial direction of the battery 420, where the battery 420 can be cylindrical, conical, etc. As another example, the thickness direction of the second housing 200 can be the thickness direction of the circuit board 430. The height direction of the second housing 200 can be the direction in which the second housing 200 recedes from or approaches the second end 330 of the connector 300, where one end of the second housing 200 in the height direction is connected to the second end 330 of the connector 300. For example, the height direction of the second housing 200 can be the width direction of the circuit board 430. The length direction of the second housing 200 can be the direction of the largest end of the second housing 200. For example, the length direction of the second housing 200 can also be the length direction of the circuit board 430.

[0073] The second housing 200 may have a mounting groove 213 on the side facing the first housing 100. The ear clip earphone may also include a flexible element 212, which can be set in the mounting groove 213 by means of bonding, snapping, welding, etc. In the wearing state, there can be a clamping force between the second housing 200 and the first housing 100 to hold the wearer's ear, and the ear clip earphone can be kept in a stable wearing state by the clamping force between the second housing 200 and the first housing 100. By setting the flexible element 212 on the side of the second housing 200 facing the first housing 100, the second housing 200 contacts and cooperates with the back of the wearer's ear through the flexible element 212, which can improve wearing comfort. The hardness of the flexible element 212 can be less than that of the second housing 200. The structure of the flexible element 212 is not limited. For example, the flexible element 212 may include a fabric structure, an elastic structure, etc. For example, the flexible component 212 can be elastic, and the material of the flexible component 212 can include rubber, silicone, etc., so that the deformation of the flexible component 212 can also improve the ability of the second housing 200 to adapt to ears of different sizes. It should be noted that the flexible component 212 can be understood as a part of the structure that makes up the second housing 200.

[0074] Example 2: The second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 may be located on the side closer to the first housing 100, and the second half-shell 220 may be located on the side farther away from the first housing 100. The first half-shell 210 and the second half-shell 220 may be connected by means of adhesive, snap-fit, welding, etc. By setting two half-shells, it is convenient to install the battery 420, circuit board 430, charging component 450, etc.

[0075] In Example 2, the first half-shell 210 may include a supporting half-shell 211 and a flexible member 212. The supporting half-shell 211 and the second half-shell 220 may be arranged opposite to each other, and the supporting half-shell 211 and the second half-shell 220 may be connected by means of bonding, snap-fitting, welding, etc.; the supporting half-shell 211 may have a mounting groove 213 on the side facing the first shell 100; the flexible member 212 may be disposed in the mounting groove 213 by means of bonding, snap-fitting, welding, etc. The hardness of the flexible member 212 may be less than the hardness of the supporting half-shell 211. The flexible member 212 has been described in the above embodiments and will not be repeated here.

[0076] In Example 2, such as Figure 6As shown, the middle portion of the flexible member 212 can be recessed inwards towards the side away from the first housing 100 to form a recessed mating surface 214, adapting to the shape of the wearer's ear. The recessed mating surface 214 is used to adapt to the shape of the wearer's ear, thereby improving the fit between the second half-shell 220 and the wearer's ear. The middle portion of the back side of the wearer's ear is generally protruding relative to the root and end of the back side of the ear. Through the recessed mating surface 214, the protruding portion of the middle portion of the back side of the ear mates with the recessed mating surface 214, allowing the root and end of the back side of the ear to contact the peripheral area of ​​the flexible member 212. This significantly increases the contact area between the flexible member 212 and the back side of the ear, reduces the distance between the flexible member 212 and the back side of the ear, and allows the flexible member 212 to fit more snugly behind the ear. The shape of the recessed mating surface 214 is not limited. For example, the recessed mating surface 214 can be a concave arc surface to make the recessed mating surface 214 smoother. The depth of the recessed mating surface 214 can gradually increase from the edge to the center. The maximum depth M3 of the recessed mating surface 214 is not limited. For example, the maximum depth M3 of the recessed mating surface 214 can be 0.1mm to 0.4mm, 0.2mm to 0.4mm, 0.3mm to 0.4mm, 0.2mm to 0.3mm, etc. Of course, in some other examples, the center of the flexible member 212 can be planar.

[0077] It is important to note that, such as Figure 3 As shown, when the ear clip earphone does not include the flexible member 212, the second housing 200 facing the first housing 100 can also be recessed inward to form a recessed mating surface 214 away from the first housing 100 to adapt to the shape of the wearer's ear. The recessed mating surface 214 has been described above and will not be repeated here.

[0078] In some embodiments, such as Figure 1 As shown, the connector 300 may include a first connecting portion 350 and a second connecting portion 360. The first connecting portion 350 may be connected to the first housing 100 by means of bonding, snap-fitting, welding, etc.; the second connecting portion 360 may be connected to the first connecting portion 350 and the second half-shell 220 by means of bonding, snap-fitting, welding, etc.

[0079] The second connecting portion 360 and the second half-shell 220 can be different parts of a single structural component to facilitate manufacturing and improve the connection strength between the second connecting portion 360 and the second half-shell 220; or, the second connecting portion 360 and the second half-shell 220 can be different structural components.

[0080] The first connecting portion 350 can be connected to the side of the first housing 100 opposite to the second housing 200 to increase the clamping space 510. The second connecting portion 360 can be connected to the second half-housing 220 to increase the clamping space 510.

[0081] The second connecting portion 360 can protrude beyond the second half-shell 220 in the height direction of the second housing 200. For example... Figure 7 As shown, the distance N4 in the thickness direction of the second shell 200 from the end of the second half-shell 220 away from the first half-shell 210 to the connection point between the first connecting portion 350 and the second connecting portion 360 can be 1mm to 2mm. By setting a suitable distance N4, the clamping space 510 can be made larger, while preventing interference between the second connecting portion 360 and the wearer's head can be prevented. Of course, the distance N4 can also be 1mm to 1.5mm, 1.5mm to 2mm, etc. Figure 7 As shown, the second connecting portion 360 may not protrude beyond the second half-shell 220 in the thickness direction of the second shell 200, so as to prevent the second connecting portion 360 from interfering with the wearer's head during wearing and affecting the smoothness of wearing the ear clip headphones.

[0082] like Figure 5 As shown, the cross-sectional area of ​​the second connecting portion 360 can gradually decrease in the direction away from the second half-shell 220. A second connecting portion 360 with a larger cross-sectional area can improve the connection strength with the second half-shell 220, while a second connecting portion 360 with a smaller cross-sectional area can reduce the size of the second connecting portion 360 and achieve weight reduction. Of course, the cross-sectional area of ​​the second connecting portion 360 can also remain unchanged. This disclosure does not limit this.

[0083] The minimum dimension N5 of the second connecting portion 360 in the thickness direction of the second housing 200 can be 2.5mm to 4mm; by using a suitable minimum dimension N5, both high connection strength and lightweight can be achieved. The minimum dimension N5 can also be 3mm to 4mm, 2.5mm to 3mm, etc.

[0084] In some optional implementations of the embodiments of this disclosure, such as Figure 3 and Figure 6 As shown, the clip-on earphone may include a connecting cable 460. A first end of the connecting cable 460 may be located within a first housing 100 and electrically connected to a sound-generating assembly 410. A second end of the connecting cable 460 may be located within a second housing 200 and electrically connected to a circuit board 430. The portion of the connecting cable 460 located between the first and second ends may be located within a connector 300.

[0085] In some optional implementations of the embodiments disclosed herein, the first housing 100 may have a sound outlet channel 140 and a pressure relief channel 150; the sound generating assembly 410 may be disposed within the first housing 100; the sound generating assembly 410 divides the space within the first housing 100 into a front cavity 101 and a rear cavity 102; the sound outlet channel 140 communicates with the front cavity 101, and the rear cavity 102 communicates with the pressure relief channel 150; one side of the sound generating assembly 410 with a diaphragm 411 faces the sound outlet channel 140. The side of 410 facing away from the diaphragm 411 faces the pressure relief channel 150; the second housing 200 may have a mounting through hole 203; the second housing 200 is provided with a battery 420 and a circuit board 430; a charging component 450 is provided at the mounting through hole 203, and the circuit board 430 is electrically connected to the sound-generating component 410, the battery 420 and the charging component 450 respectively; the first end 320 of the connector 300 is connected to the first housing 100, and the second end 330 of the connector 300 is connected to the second housing 200.

[0086] In some optional implementations of the embodiments of this disclosure, the maximum dimensions of the first housing 100 in the first direction, the second direction, and the third direction can be 12 mm to 16 mm; wherein the first direction is perpendicular to the second direction and the third direction, respectively.

[0087] In this implementation, the first direction, the second direction, and the third direction are not limited. For example, the first direction can be the length direction of the first housing 100, the second direction can be the width direction of the first housing 100, and the third direction can be the height direction of the first housing 100. As another example, the first direction can be the height direction of the second housing 200, the second direction can be the thickness direction of the second housing 200, and the third direction can be the length direction of the second housing 200. This disclosure does not limit these aspects.

[0088] The inventors discovered that the size design of clip-on headphones in related technologies has poor fit with the wearer's ears, easily causing discomfort. For example, if the size of the first shell 100 is too small, it is easy for the first shell 100 to become loose, causing frequent shaking and audio information leakage. Conversely, if the size of the first shell 100 is too large, it is easy for the first shell 100 to compress the wearer's concha, causing ear pain with prolonged wear. The clip-on headphones of this disclosure, by setting the size of the first shell 100 more appropriately in three directions, can make the first shell 100 fit more snugly against the wearer's concha, reducing the gap or interference between the first shell 100 and the wearer's concha. This improves the wearing stability of the first shell 100 in the concha and reduces the pressure caused by the first shell 100 on the wearer's concha.

[0089] In this implementation, the maximum dimensions of the first housing 100 in the first direction, the second direction, and the third direction can also be 12mm to 15mm, 12mm to 14mm, 13mm to 14mm, 13.5mm to 14.5mm, 13mm to 16mm, 14mm to 16mm, etc. The maximum dimensions of the first housing 100 in the first direction, the second direction, and the third direction can be the same or different.

[0090] In this implementation, the first housing 100 may include a first portion disposed adjacent to the second housing 200 and a second portion disposed opposite to the second housing 200; the first end of the connector 300 may be connected to the second portion of the first housing 100; the second end of the connector 300 may be connected to the side of the second housing 200 away from the first housing 100; thereby increasing the size of the clamping space 510 in the thickness direction of the second housing 200, improving the ability of the ear clip headphones to adapt to large ears, and reducing the possibility of the ear clip headphones squeezing the wearer's ears; and / or, as Figure 3 As shown, the battery 420 can be located inside the second housing 200 on the side closer to the first housing 100, while the circuit board 430 and the charging component 450 can be located inside the second housing 200 on the side farther from the first housing 100. The second end of the connector 300 can be connected to the side of the second housing 200 away from the first housing 100, and the second end of the connecting wire 460 can be located inside the second housing 200 on the side farther from the first housing 100, so as to reduce the distance between the second end of the connecting wire 460 and the circuit board 430 and facilitate wiring.

[0091] In this implementation, the first housing 100 may include a first part disposed adjacent to the second housing 200 and a second part disposed opposite to the second housing 200; the first end of the connector 300 is connected to the second part of the first housing 100; wherein, the second part of the first housing 100 may be hemispherical, and the diameter L1 of the second part of the first housing 100 may be 12mm to 16mm; by setting the second part of the first housing 100 opposite to the second housing 200 to a hemispherical structure of appropriate size, the surface of the second part of the first housing 100 can be smoother, further improving the wearing safety of the second part of the first housing 100.

[0092] In this implementation, the first housing 100 may include a support housing 110 and an elastic housing 120. A sound-generating component 410 may be disposed within the support housing 110; the sound-generating component 410 may divide the space within the support housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may wrap around the support housing 110; wherein, the elastic housing 120 forms a first part of the first housing 100, and the support housing 110 and the elastic housing 120 form a second part of the first housing 100; by wrapping the support housing 110 with the elastic housing 120, the wearing comfort of the first housing 100 can be further improved.

[0093] The above embodiments have already described the support shell 110 and the elastic shell 120, and will not be repeated here. For example, the elastic shell 120 may include an opening 121, through which a portion of the support shell 110 may be located within the cavity defined by the elastic shell 120; a deformation space 130 may be defined between the elastic shell 120 and the support shell 110. As another example, the elastic shell 120 may include an opening 121, through which the elastic shell 120 may be fitted over the portion of the support shell 110 facing the second shell 200; the opening 121 may be constricted; and / or, the surface area of ​​the support shell 110 enclosed by the elastic shell 120 may be larger than the surface area of ​​the support shell 110 in its exposed state. For example, the support shell 110 may have a first sound outlet 116; the elastic shell 120 may cover the area of ​​the support shell 110 where the first sound outlet 116 is located; the elastic shell 120 may have a second sound outlet 122 corresponding to the position of the first sound outlet 116; the sound outlet channel 140 may include the first sound outlet 116 and the second sound outlet 122; the first sound outlet 116 communicates with the front cavity 101; the support shell 110 may also have a first through hole 117 communicating with the rear cavity 102; the elastic shell 120 may cover the area of ​​the support shell 110 where the first through hole 117 is located; the elastic shell 120 may have a second through hole 123 corresponding to the position of the first through hole 117; the pressure relief channel 150 may include the first through hole 117 and the second through hole 123. Here, a deformable space 130 is defined between the elastic shell 120 and the support shell 110; the deformable space 130 communicates with the outside through the second through hole 123; and / or, the deformable space 130 communicates with the outside through the second sound outlet hole 122. For example, the elastic shell 120 is used to fit with the wearer's ear; and / or, the support shell 110 may include a connecting region 111 connected to the first end 320 of the connector 300, and an annular groove 112 formed along the outer periphery of the connecting region 111; the elastic shell 120 may include an opening 121, through which the elastic shell 120 is fitted over the portion of the support shell 110 facing the second shell 200, and the elastic shell 120 has an annular protrusion 124 at the opening 121, which can be inserted into the annular groove 112. For another example, the elastic shell 120 and the support shell 110 may be detachably connected; and / or, the support shell 110 may be a rigid structure.

[0094] In some of the implementations disclosed herein, Figure 1 As shown, the side of the first housing 100 facing the second housing 200 can deform, and the deformation amount L4 of the side of the first housing 100 facing the second housing 200 can be 0 to 3 mm.

[0095] The inventors discovered that the size design of clip-on headphones in related technologies has poor fit with the wearer's ears, easily causing discomfort. For example, the side of the sound-generating structure facing the power supply structure is used to clamp the wearer's ear in conjunction with the power supply structure. If the distance between the sound-generating structure and the power supply structure is too large, it is easy to cause the ear to loosen due to insufficient clamping; if the distance between the sound-generating structure and the power supply structure is too small, it is easy to cause pain to the wearer's ear. In contrast, the clip-on headphones disclosed in this invention, by allowing the first shell 100 of the ear clip-on headphones to deform on the side facing the second shell 200, can have a relatively large size on the side facing the second shell 200. This not only provides clamping force between the first shell 100 and the second shell 200, improving wearing stability, but also reduces the maximum clamping force between the first shell 100 and the second shell 200 due to the deformability, thus improving wearing comfort.

[0096] In this implementation, the deformation amount L4 of at least a portion of the first housing 100 facing the second housing 200 is greater than 0. The deformation amount L4 of the first housing 100 facing the second housing 200 can also be 0 to 2.5 mm, 0 to 2 mm, 0 to 1 mm, 0 to 1.5 mm, 0.5 mm to 3 mm, 0.1 mm to 3 mm, 1 mm to 3 mm, 1.5 mm to 3 mm, 2 to 3 mm, etc. The deformation amounts of each region of the first housing 100 facing the second housing 200 can be the same or different. For example, the deformation amount L4 of a portion of the first housing 100 facing the second housing 200 can be 0; in other words, a portion of the first housing 100 facing the second housing 200 cannot deform. The deformation amount L4 of the remaining portion of the first housing 100 facing the second housing 200 can be greater than 0. Alternatively, the deformation amount L4 of all regions of the first housing 100 facing the second housing 200 can be greater than 0.

[0097] In this implementation, such as Figure 4 As shown, the first end 320 of the connector 300 can be connected to the side of the first housing 100 facing away from the second housing 200; the size L5 of the first housing 100 end of the ear clip earphone after the maximum deformation under pressure in the thickness direction of the second housing 200 can be 9mm to 14mm. The first housing 100 end of the ear clip earphone includes the first housing 100 and the part where the first end 320 of the connector 300 is connected to the first housing 100. By setting the size L5 of the first housing 100 end of the ear clip earphone after the maximum deformation under pressure in the thickness direction of the second housing 200 appropriately, it is possible to improve the ability of the ear clip earphone to adapt to different sizes of ears and to maximize the miniaturization of the ear clip earphone.

[0098] The maximum deformed dimension L5 can also be 11mm to 12mm, 9mm to 13mm, 9mm to 12mm, 9mm to 11mm, 9mm to 10mm, 10mm to 14mm, 11mm to 14mm, 12mm to 14mm, 13mm to 14mm, 12.5mm to 13.5mm, etc.

[0099] The dimension L2 of the first housing 100 after maximum deformation under pressure in the thickness direction of the second housing 200 can be 8mm to 13mm; and / or, the first end 320 of the connector 300 protrudes from the thickness L7 of the first housing 100 in the thickness direction of the second housing 200 by 0.5mm to 1.5mm. The dimension L2 after maximum deformation can also be 8mm to 12mm, 8mm to 11mm, 8mm to 10mm, 8mm to 9mm, 9mm to 13mm, 10mm to 13mm, 11mm to 13mm, 12mm to 13mm, 10mm to 12mm, etc. The thickness L7 can also be 0.5mm to 1mm, 0.5mm to 0.75mm, 1mm to 1.5mm, 0.75mm to 1.5mm, etc. The dimension L3 of the first housing 100 without pressure in the width direction of the second housing 200 can be 11mm to 16mm, 12mm to 15mm, 13mm to 14mm, etc.

[0100] In this implementation, such as Figure 4 As shown, the first end 320 of the connector 300 is connected to the side of the first housing 100 opposite to the second housing 200; the dimension L6 of the first housing 100 end of the ear clip earphone, which is not compressed in the thickness direction of the second housing 200, can be 11.5mm to 15.5mm; the first housing 100 end of the ear clip earphone includes the first housing 100 and the portion where the first end 320 of the connector 300 connects to the first housing 100. By setting the dimension L6 appropriately, the ability of the ear clip earphone to adapt to larger ears can be improved, as can the wearing stability of the ear clip earphone. The dimension L6 can also be 12.5mm to 14.5mm, 13.5mm to 15.5mm, 11.5mm to 13.5mm, 13.5mm to 14.5mm, etc.

[0101] In this implementation, the connector 300 in the height direction of the second housing 200 has a high point region 310 with the greatest distance from the second housing 200; the end of the first housing 100 facing the high point region 310 can deform, thereby improving the ability of the clamping space 510 to adapt to different sizes of ears. The dimension L7 of the first housing 100 after maximum deformation under pressure in the height direction of the second housing 200 can be 11.5mm to 15.5mm. By setting the dimension L7 appropriately, the ability of the ear clip headphones to adapt to different sizes of ears can be improved, and the miniaturization of the ear clip headphones can be maximized. The dimension L7 can also be 11.5mm to 14.5mm, 11.5mm to 13.5mm, 11.5mm to 12.5mm, 12.5mm to 15.5mm, 13.5mm to 15.5mm, 13.5mm to 14.5mm, etc. One end of the first housing 100 facing the high point region 310 can be the end of the first housing 100 facing the high point region 310 and close to the second housing 200.

[0102] In this implementation, the connector 300 in the height direction of the second housing 200 can have a high point region 310 with the greatest distance from the second housing 200; the end of the first housing 100 facing the high point region 310 can deform, and the dimension L8 of the first housing 100 not under pressure in the height direction of the second housing 200 can be 12mm to 16mm; by setting the dimension L8 appropriately, both the ability of the ear clip headphones to adapt to different ear sizes can be improved, and the wearing stability of the ear clip headphones can also be improved. The dimension L8 can also be 12mm to 15mm, 12mm to 14mm, 12mm to 13mm, 13mm to 16mm, 14mm to 16mm, 15mm to 16mm, 13mm to 15mm, etc.

[0103] In this implementation, the first housing 100 may include a supporting housing 110 and an elastic housing 120; a sound-emitting component 410 may be disposed within the supporting housing 110; the sound-emitting component 410 divides the space within the supporting housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the supporting housing 110 facing the second housing 200; a deformation space 130 may be defined between the elastic housing 120 and the supporting housing 110, and the elastic housing 120 may deform based on the deformation space 130, thereby increasing the amount of deformation. Of course, in some other examples, the deformation space 130 may not be provided, and the elastic housing 120 may deform based on its own elasticity. Alternatively, the first housing 100 may be elastic in its entirety or in part, and the first housing 100 may also deform by being elastic in its entirety or in part; this disclosure does not limit this.

[0104] Here, as Figure 6As shown, the connector 300 in the height direction of the second housing 200 may have a high point region 310 with the greatest distance from the second housing 200; the deformation space 130 may include a first space 131 located between the support shell 110 and the second housing 200, and a second space 132 located between the high point region 310 and the support shell 110; and / or, the elastic shell 120 can deform away from the second housing 200 based on the deformation space 130, and deform away from the high point region 310 based on the deformation space 130. The first space 131 can increase the amount of deformation of the elastic shell 120 in the thickness direction of the second housing 200, thereby improving the adaptability of the clamping gap 520 between the second housing 200 and the elastic shell 120; the second space 132 can increase the amount of deformation of the elastic shell 120 in the height direction of the second housing 200, thereby improving the adaptability of the clamping space 510. Of course, in some other examples, only one of the first space 131 and the second space 132 may be provided.

[0105] The elastic shell 120 can deform away from the second shell 200 based on the deformation space 130, which can increase the amount of deformation of the elastic shell 120 in the thickness direction of the second shell 200, thereby improving the adaptability of the clamping gap 520 between the second shell 200 and the elastic shell 120; the elastic shell 120 can deform away from the high point region 310 based on the deformation space 130, which can increase the amount of deformation of the elastic shell 120 in the height direction of the second shell 200, thereby improving the adaptability of the clamping space 510.

[0106] The above embodiments have already described the support shell 110 and the elastic shell 120, and will not be repeated here. For example, the support shell 110 may have a first sound outlet 116; the elastic shell 120 may cover the area of ​​the support shell 110 where the first sound outlet 116 is located; the elastic shell 120 may have a second sound outlet 122 corresponding to the position of the first sound outlet 116; the sound outlet channel 140 includes the first sound outlet 116 and the second sound outlet 122; the first sound outlet 116 communicates with the front cavity 101; the support shell 110 may also have a first through hole 117 communicating with the rear cavity 102; the elastic shell 12 ... The elastic shell 120 surrounds the area of ​​the support shell 110 where the first through hole 117 is located; the elastic shell 120 has a second through hole 123 corresponding to the position of the first through hole 117; the deformation space 130 communicates with the outside through the second sound outlet 122; the pressure relief channel 150 includes the first through hole 117 and the second through hole 123; wherein, the deformation space 130 can communicate with the outside through the second through hole 123; and / or, the deformation space 130 can communicate with the outside through the second sound outlet 122. For example, the number of elastic shells 120 can be at least two, and one of the at least two elastic shells 120 can be detachably connected to the support shell 110; the at least two elastic shells 120 can be identical; or, the deformation spaces 130 defined between the at least two elastic shells 120 and the support shell 110 can be different, so that the at least two elastic shells 120 have different maximum deformation amounts.

[0107] In some implementations of the embodiments of this disclosure, the connector 300 in the height direction of the second housing 200 has a high point region 310 that is at the greatest distance from the second housing 200, and the side of the first housing 100 facing the second housing 200 includes a first end close to the high point region 310 and a second end away from the high point region 310 in the height direction of the second housing 200; from the first end of the first housing 100 to the second end of the first housing 100, the amount of deformation of the first housing 100 in the direction away from the second housing 200 gradually decreases.

[0108] The inventors discovered that the side of the sound-generating structure facing the power supply structure is used to clamp the wearer's ear in conjunction with the power supply structure. However, this side of the sound-generating structure does not match the shape of the wearer's concha, easily causing some areas to be too far from the concha and resulting in movement, while other areas may experience excessive pressure on the concha, causing wearing pain. The ear clip-on earphone disclosed herein, by gradually reducing the deformation of the first housing 100 in the direction away from the second housing 200 from its first end to its second end, allows the first side of the first housing 100 to adapt to the shape deformation of the wearer's concha, increasing the fit between the first side of the first housing 100 and the wearer's concha, improving wearing stability, reducing the pressure of the first side of the first housing 100 on the wearer's concha, and improving wearing comfort.

[0109] In this implementation, the end of the first housing 100 facing the high point region 310 is deformable. The maximum deformation L9 of this end of the first housing 100 facing the high point region 310 under pressure in the height direction of the second housing 200 can be 0.5mm to 2mm, to improve the adaptability of the clamping space 510 to the shape and size of the ear. Of course, the maximum deformation L9 can also be 0.5mm to 1.5mm, 0.5mm to 1mm, 1mm to 2mm, 1.5mm to 2mm, etc. Of course, in some other implementations, the end of the first housing 100 facing the high point region 310 may not be deformable. This disclosure does not limit this.

[0110] In this implementation, the first housing 100 may include a support housing 110 and an elastic housing 120; a sound-emitting component 410 may be disposed within the support housing 110, dividing the space within the support housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the support housing 110 facing the second housing 200; a deformation space 130 may be defined between the elastic housing 120 and the support housing 110, and the elastic housing 120 may include a first end near the high point region 310 and a second end away from the high point region 310 in the height direction of the second housing 200; from the first end 126 to the second end 127 of the elastic housing 120, the size of the deformation space 130 gradually decreases; thereby, the deformation amount gradually decreases through the deformation space 130. Of course, in some other implementations, the deformation space 130 may not be provided. For example, from the first end 126 of the elastic shell 120 to the second end 127 of the elastic shell 120, the thickness of the elastic shell 120 may be gradually reduced, thereby achieving a gradual reduction in the amount of deformation through the deformation of the elastic shell 120 itself.

[0111] In this implementation, the deformation space 130 may include a first space 131 located between the support shell 110 and the second shell 200, and a second space 132 located between the high point region 310 and the support shell 110; and / or, the elastic shell 120 is capable of deforming away from the second shell 200 based on the deformation space 130, and is also capable of deforming away from the high point region 310 based on the deformation space 130. The deformation space 130 has been described in the above embodiments and will not be repeated here.

[0112] In this implementation, the deformation L4 of the first housing 100 in the direction away from the second housing 200 can be 0 to 3 mm. Of course, the deformation L4 can also be 0 to 2 mm, 0 to 1 mm, 0.5 mm to 3 mm, 1 mm to 3 mm, 1.5 mm to 3 mm, 2 mm to 3 mm, etc.

[0113] In this implementation, the elastic shell 120 protrudes from the first end 113 of the support shell 110 towards the high point region 310 and towards the second shell 200, so that the deformation space 130 of the elastic shell 120 at the first end 113 of the support shell 110 is maximized; and / or, the wall thickness of the elastic shell 120 in each region is the same or close; by maximizing the deformation space 130 of the elastic shell 120 at the first end 113 of the support shell 110, both the ability of the clamping space 510 to adapt to different ear sizes can be improved, and the ability of the clamping gap 520 between the first shell 100 and the second shell 200 to adapt to different ear sizes can also be improved.

[0114] In this implementation, such as Figure 6 and Figure 9 As shown, the distance between the first surface 115 of the support shell 110 facing the second shell 200 and the elastic shell 120 can first increase and then decrease along the length of the second shell 200; the first surface 115 can be a plane; and / or, the first wall 125 of the elastic shell 120 opposite to the first surface 115 can be an arc-shaped structure. By allowing the distance between the first surface 115 and the elastic shell 120 to first increase and then decrease along the length of the second shell 200, the overall deformation of the elastic shell 120 can be increased, while the elastic shell 120 can be set relatively small and the support shell 110 relatively large. Thus, with the same amount of deformation, miniaturization of the ear clip-on earphone can be achieved. Of course, in other examples, the distance between the first surface 115 and the elastic shell 120 can also continuously increase, continuously decrease, or remain constant along the length of the second shell 200. This disclosure does not limit this.

[0115] The above embodiments have already described the support shell 110 and the elastic shell 120, and will not be repeated here. For example, the support shell 110 may have a first sound outlet 116; the elastic shell 120 may cover the area of ​​the support shell 110 where the first sound outlet 116 is located; the elastic shell 120 may have a second sound outlet 122 corresponding to the position of the first sound outlet 116; the sound outlet channel 140 includes the first sound outlet 116 and the second sound outlet 122; the support shell 110 may also have a first through hole 117 communicating with the rear cavity 102; the elastic shell 120 may cover the area of ​​the support shell 110 where the first through hole 117 is located; the elastic shell 120 may have a second through hole 123 corresponding to the position of the first through hole 117; the pressure relief channel 150 may include the first through hole 117 and the second through hole 123. Here, the deformation space 130 may communicate with the outside through the second through hole 123; and / or, the deformation space 130 may communicate with the outside through the second sound outlet 122.

[0116] In this implementation, the first end of the connector 300 can be connected to the side of the first housing 100 facing away from the first housing 100; the second end of the connector 300 can be connected to the side of the second housing 200 away from the first housing 100, so as to increase the clamping space 510 and thereby improve the ability of the ear clip headphones to adapt to large-sized ears.

[0117] In some implementations of the embodiments of this disclosure, such as Figure 5 As shown, the second housing 200 may include one end close to the first housing 100 and another end away from the first housing 100 in the thickness direction. The thickness N1 between the end of the second housing 200 close to the first housing 100 and the other end away from the first housing 100 may be 8 mm to 13 mm.

[0118] The inventors discovered that the power supply structure design of clip-on earphones has poor fit with the wearer's ears, easily causing discomfort. For example, if the thickness of the power supply structure is too large, it can easily compress the back of the wearer's ear and head; if the thickness is too small, the second shell 200 can easily wobble after wearing. The clip-on earphones disclosed in this invention, by setting a more suitable thickness N1 between the end of the second shell 200 closest to the first shell 100 and the end furthest from the first shell 100, can improve both wearing stability and comfort.

[0119] In this implementation, the thickness N1 can also be 8mm to 12mm, 8mm to 11mm, 8mm to 10mm, 9mm to 13mm, 10mm to 13mm, 11mm to 13mm, 12mm to 13mm, 10mm to 12mm, etc.

[0120] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 may be located closer to the first housing 100, and the second half-shell 220 may be located farther from the first housing 100; wherein, the thickness N2 of the first half-shell 210 may be less than the thickness N3 of the second half-shell 220, and the second end 330 of the connector 300 may be connected to the thicker second half-shell 220 to improve the connection strength. Of course, in other examples, the thickness N2 of the first half-shell 210 may also be greater than or equal to the thickness N3 of the second half-shell 220.

[0121] The thickness N2 of the first half-shell 210 can be 3mm to 5mm; and / or, the thickness N3 of the second half-shell 220 can be 5mm to 9mm. Of course, the thickness N2 can also be 3mm to 4mm, 4mm to 5mm, etc. The thickness N3 can be 5mm to 8mm, 5mm to 7mm, 5mm to 6mm, 6mm to 8mm, etc.

[0122] In this implementation, the connector 300 may include a first connecting portion 350 and a second connecting portion 360. The first connecting portion 350 may be connected to the first housing 100; the second connecting portion 360 may be connected to the first connecting portion 350 and the second half-shell 220 respectively; the second connecting portion 360 protrudes from the second half-shell 220 in the height direction of the second housing 200.

[0123] The first connecting portion 350 and the second connecting portion 360 have been described in the above embodiments and will not be repeated here. For example, the distance N4 between the end of the second half-shell 220 away from the first half-shell 210 and the connection point of the first connecting portion 350 and the second connecting portion 360 in the thickness direction of the second housing 200 can be 1 mm to 2 mm; and / or, the second connecting portion 360 does not protrude from the second half-shell 220 in the thickness direction of the second housing 200. As another example, the cross-sectional area of ​​the second connecting portion 360 gradually decreases in the direction away from the second half-shell 220, and the minimum dimension N5 of the second connecting portion 360 in the thickness direction of the second housing 200 can be 2.5 mm to 4 mm.

[0124] In this implementation, the first half-shell 210 may include a supporting half-shell 211 and a flexible member 212. The supporting half-shell 211 is disposed opposite to the second half-shell 220; the supporting half-shell 211 may have a mounting groove 213 on the side facing the first shell 100; the flexible member 212 may be disposed in the mounting groove 213, and the wearing comfort can be improved by contacting the wearer's ear through the flexible member 212.

[0125] The above embodiments have already described the flexible member 212 and the supporting half-shell 211. Further details will not be repeated here. For example, the middle portion of the flexible member 212 may be recessed inwards towards the side away from the first shell 100 to form a recessed mating surface 214 to adapt to the shape of the wearer's ear; and / or, the flexible member 212 may be elastic.

[0126] In this implementation, the battery 420 can be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the circuit board 430 can be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the mounting through hole 203 can be formed in the second half-shell 220, wherein the axial direction of the battery 420 and the thickness direction of the second shell 200 can be the same; and / or, the thickness direction of the circuit board 430 and the thickness direction of the second shell 200 can be the same, so as to make reasonable use of the space defined by the first half-shell 210 and the second half-shell 220.

[0127] In this implementation, the first housing 100 may include a supporting housing 110 and an elastic housing 120; a sound-generating component 410 may be disposed within the supporting housing 110; the sound-generating component 410 divides the space within the supporting housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the supporting housing 110 facing the second housing 200; a deformation space 130 may be defined between the elastic housing 120 and the supporting housing 110, and the elastic housing 120 may be deformable based on the deformation space 130. The supporting housing 110 and the elastic housing 120 have been described in the above embodiments and will not be repeated here.

[0128] In some implementations of the embodiments of this disclosure, such as Figure 7 As shown, the height N6 of the second housing 200 can be from 13mm to 17mm.

[0129] The inventors discovered that the power supply structure design of clip-on headphones has poor fit with the wearer's ears, easily causing discomfort. For example, if the height of the power supply structure is too large, it can be pushed up by the wearer's head, resulting in a large gap between the clip-on headphones and the wearer's ear helix, leading to instability. If the height of the power supply structure is too small, the gap between it and the wearer's head can be too large, causing the power supply structure to wobble. The clip-on headphones disclosed in this invention, by setting a more suitable height N6 for the second shell 200, allow the second shell 200 to fit more snugly against the wearer's head and ears; it also reduces the risk of a large gap between the connector 300 and the wearer's ear helix, thereby improving wearing stability and comfort.

[0130] In this implementation, the height N6 of the second housing 200 can also be 14mm to 15mm, 13mm to 16mm, 13mm to 15mm, 13mm to 14mm, 14mm to 17mm, 15mm to 17mm, 16mm to 17mm, 14mm to 16mm, etc.

[0131] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 is located on the side closer to the first housing 100, and the second half-shell 220 is located on the side farther from the first housing 100; wherein, the height of the second housing 200 is the height of the second half-shell 220; the height of the second half-shell 220 may be greater than the height of the first half-shell 210. By setting the height of the second half-shell 220 to be larger, it is easier for the second half-shell 220 to be connected to the second end 330 of the connector 300, and by setting the height of the first half-shell 210 to be smaller, the clamping space 510 can be increased.

[0132] In this implementation, the connector 300 may include a first connecting portion 350 and a second connecting portion 360. The first connecting portion 350 may be connected to the first housing 100; the second connecting portion 360 may be connected to the first connecting portion 350 and the second half-shell 220 respectively; the second connecting portion 360 protrudes from the second half-shell 220 in the height direction of the second housing 200.

[0133] The second connecting portion 360 protrudes from the second half-shell 220 in the height direction of the second housing 200 by a dimension N7 that can be from 1.5mm to 3.5mm. The cross-sectional area of ​​the second connecting portion 360 can gradually decrease in the direction away from the second half-shell 220. By separating the second connecting portion 360 with its varying cross-sectional area from the first connecting portion 350, manufacturing is facilitated. The second connecting portion 360 connects to the second half-shell 220 via its larger cross-sectional area side, which improves the connection strength. The second connecting portion 360 connects to the first connecting portion 350 via its smaller cross-sectional area side, which reduces the size of the connector 300 and achieves miniaturization of the connector 300.

[0134] The second connecting portion 360 protrudes from the second half-shell 220 in the height direction of the second housing 200. The size N7 can also be 1.5mm to 3mm, 1.5mm to 2.5mm, 1.5mm to 2mm, 2mm to 3.5mm, 2.5mm to 3.5mm, 3mm to 3.5mm, 2mm to 3mm, etc.

[0135] The second connecting portion 360 can be connected to the side of the second half-shell 220 away from the first half-shell 210 to increase the clamping space 510; and / or, the distance N4 between the connection point of the end of the second half-shell 220 away from the first half-shell 210 and the first connecting portion 350 and the second connecting portion 360 in the thickness direction of the second shell 200 can be 1mm to 2mm to prevent the second connecting portion 360 from interfering with the wearer's head and affecting the wearing stability. The distance N4 has been described in the above embodiments and will not be repeated here.

[0136] In this implementation, the first half-shell 210 may include a supporting half-shell 211 and a flexible member 212. The supporting half-shell 211 may be disposed opposite to the second half-shell 220; a mounting groove 213 may be formed on the side of the supporting half-shell 211 facing the first shell 100; the flexible member 212 may be disposed within the mounting groove 213. The supporting half-shell 211 and the flexible member 212 have been described in the above embodiments and will not be repeated here. For example, the middle part of the flexible member 212 may be recessed inward toward the side away from the first shell 100 to form a recessed mating surface 214 to adapt to the shape of the wearer's ear; and / or, the flexible member 212 may be elastic.

[0137] In this implementation, the battery 420 can be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the circuit board 430 can be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the mounting through hole 203 is formed in the second half-shell 220, wherein the axial direction of the battery 420 and the thickness direction of the second shell 200 can be the same; and / or, the thickness direction of the circuit board 430 and the thickness direction of the second shell 200 can be the same.

[0138] In this implementation, such as Figure 2 As shown, the length N8 of the second housing 200 can be from 19mm to 23mm. By setting the length N8 of the second housing 200 appropriately, the second housing 200 can fit more snugly against the wearer's ears and head, thereby improving the wearing stability and comfort of the second housing 200. The length N8 can also be 20mm to 22mm, 20.5mm to 21.5mm, 19mm to 21mm, 21mm to 23mm, etc.

[0139] In this implementation, the first housing 100 may include a supporting housing 110 and an elastic housing 120; a sound-generating component 410 may be disposed within the supporting housing 110; the sound-generating component 410 divides the space within the supporting housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the supporting housing 110 facing the second housing 200; a deformation space 130 is defined between the elastic housing 120 and the supporting housing 110, and the elastic housing 120 is deformable based on the deformation space 130. The supporting housing 110 and the elastic housing 120 have been described in the above embodiments and will not be repeated here.

[0140] In some implementations of the disclosed embodiments, the second housing 200 may have a mounting groove 213 on the side facing the first housing 100; the ear clip earphone may include a flexible member 212, which may be disposed in the mounting groove 213.

[0141] The inventors discovered that when wearing earphones, the portion of the earphone structure located behind the wearer's earlobe can easily cause discomfort and pain. The earphones of this application, by incorporating a flexible component 212, make the area where the second shell 200 meets the wearer's ear more flexible, reducing the likelihood of the second shell 200 causing discomfort and pain, thereby improving the comfort of wearing clip-on earphones.

[0142] The flexible member 212 has been described in the above embodiments and will not be repeated here. For example, the middle part of the flexible member 212 may be recessed inward to form a recessed mating surface 214 away from the first housing 100 to adapt to the shape of the wearer's ear; and / or, the flexible member 212 is elastic.

[0143] In this implementation, the flexible element 212 can be detachably installed in the mounting groove 213 so that it can be replaced in time if it is damaged; and / or, the outer edge of the flexible element 212 can be flush or nearly flush with the outer surface of the second housing 200 at the groove of the mounting groove 213, so that the side of the second housing 200 facing the first housing 100 is set more smoothly. The side of the second housing 200 facing the first housing 100 fits the wearer's ear with a smoother surface, which can prevent sharp corners from hurting the wearer and improve wearing comfort.

[0144] In this implementation, the second housing 200 is adjacent to the first housing 100 in the thickness direction; the mounting groove 213 can be located on the side of the second housing 200 facing the first housing 100 in the thickness direction; and / or, the second housing 200 has a larger dimension in the length direction than in the height direction; the mounting groove 213 has a larger dimension in the length direction than in the height direction, and the length direction of the mounting groove 213 can be the same as the length direction of the second housing 200. The second housing 200 engages with the wearer's ear through the clamping gap 520 between the flexible member 212 and the first housing 100. The relatively soft flexible member 212 can provide a more uniform wearing clamping force, preventing excessive local stress from causing pain to the wearer's ear, thereby improving wearing comfort. The height direction of the mounting groove 213 can be the same as the height direction of the second housing 200. By making the setting direction of the mounting groove 213 correspond to the setting direction of the second housing 200, a larger area of ​​the mounting groove 213 can be provided, and the appearance of the second housing 200 can be improved.

[0145] In this implementation, the cross-sectional shapes of the mounting groove 213, the flexible member 212, and the second housing 200 are not limited. For example, the cross-section of the mounting groove 213 in the thickness direction of the second housing 200 can be elliptical, and the cross-section of the flexible member 212 in the thickness direction of the second housing 200 can be elliptical; and / or, the cross-section of the second housing 200 in the thickness direction can be elliptical. An elliptical cross-section of the second housing 200 in the thickness direction makes the outer surface of the second housing 200 smoother, improving the wearing comfort of the second housing 200 and preventing sharp corners from causing pain to the wearer. The elliptical cross-sections of the mounting groove 213 and the flexible member 212 in the thickness direction of the second housing 200 can match the shape of the second housing 200, thereby maximizing the cross-sectional area of ​​the mounting groove 213 and the flexible member 212, and thus increasing the installation area of ​​the flexible member 212 and the contact area with the wearer's ear. Here, the depth direction of the mounting groove 213 can be the same as or close to the thickness direction of the second housing 200, and the thickness direction of the flexible member 212 can be the same as or close to the thickness direction of the second housing 200.

[0146] In this implementation, such as Figure 6 and Figure 10 As shown, the depth E1 of the mounting groove 213 can be 0.3mm to 0.5mm; and / or, the length E2 of the mounting groove 213 can be 15mm to 19mm; and / or, the width E3 of the mounting groove 213 can be 9mm to 13mm. Setting a suitable depth E1 for the mounting groove 213 can increase the thickness of the flexible member 212 without affecting the strength of the second housing 200. Setting a suitable length E2 for the mounting groove 213 can increase the dimensions of the flexible member 212 without affecting the strength of the second housing 200. Setting a suitable width E3 for the mounting groove 213 can increase the dimensions of the flexible member 212 without affecting the strength of the second housing 200.

[0147] Depth E1 can also be 0.3mm to 0.4mm, 0.4mm to 0.5mm, etc. Length E2 can also be 15mm to 18mm, 15mm to 17mm, 15mm to 16mm, 16mm to 19mm, 17mm to 19mm, 18mm to 19mm, 16mm to 18mm, etc. Width E3 can also be 10mm to 12mm, 10mm to 11mm, 11mm to 12mm, 9mm to 11mm, 11mm to 13mm, etc.

[0148] In this implementation, one end of the second housing 200 in the height direction can be connected to the second end of the connector 300; and / or, the thickness of the flexible member 212 increases from the middle to the edge and then decreases, so that the flexible member 212 forms the highest point on the side of the second housing 200 facing the first housing 100. In other words, during the wearing process, the highest point of the flexible member 212 contacts the wearer first, which can improve wearing comfort.

[0149] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 is located on the side closer to the first housing 100, and the second half-shell 220 is located on the side farther from the first housing 100; the first half-shell 210 has a mounting groove 213; the battery 420 may be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the circuit board 430 may be disposed within the space defined by the first half-shell 210 and the second half-shell 220; wherein, the axial direction of the battery 420 is the same as the thickness direction of the second housing 200; and / or, the thickness direction of the circuit board 430 is the same as the thickness direction of the second housing 200; by providing two half-shells, it is convenient to install the battery 420 and the circuit board 430.

[0150] In this implementation, the length N8 of the second housing 200 can be from 19 mm to 23 mm; and / or, at least a portion of the flexible member 212 protrudes from the mounting groove 213, and the distance between the flexible member 212 and the first housing 100 in the thickness direction of the second housing 200 is less than the distance between the second housing 200 and the first housing 100. By placing the flexible member 212 closer to the first housing 100, the wearer's ear can be clamped by the flexible member 212 and the first housing 100, thereby improving wearing comfort. The length N8 of the second housing 200 has been described in the above embodiment and will not be repeated here.

[0151] In this implementation, the first housing 100 may include a supporting housing 110 and an elastic housing 120; a sound-emitting component 410 is disposed within the supporting housing 110, dividing the space within the supporting housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the supporting housing 110 facing the second housing 200; a deformation space 130 may be defined between the elastic housing 120 and the supporting housing 110, and the elastic housing 120 is deformable based on the deformation space 130. The supporting housing 110 and the elastic housing 120 have been described in the above embodiments and will not be repeated here.

[0152] In some implementations of the embodiments of this disclosure, such as Figure 8 As shown, the first housing 100, the connector 300, and the second housing 200 form a clamping space 510. On the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X. The clamping space 510 forms a projection curve on the coordinate system composed of the first coordinate axis Y and the second coordinate axis X. The distance D2 between the highest point 340 of the projection curve and the second coordinate axis X can be 24mm to 25mm.

[0153] The inventors discovered that the size design of clip-on headphones is poorly adapted to the wearer's ear, easily causing discomfort. For example, when wearing the headphones, the headphone structure is often pushed up by the wearer's ear helix, causing the sound-producing structure to not fit snugly against the wearer's concha, resulting in unstable wear and affecting the headphone's audio performance. However, the headphones of this application, by setting a more reasonable distance D2 between the highest point 340 of the projection curve and the second coordinate axis X, can reduce the risk of the connector 300 being pushed up by the wearer's ear helix, allowing the sound-producing component 410 to fit snugly against the wearer's concha, thereby improving the wearing stability and audio performance of the clip-on headphones.

[0154] In this implementation, the distance D2 can also be 24mm to 24.5mm, 24mm to 24.3mm, 24.5mm to 25mm, 24.3mm to 25mm, etc.

[0155] In this implementation, such as Figure 2 As shown, the projection plane F9 can be parallel to the thickness direction of the second housing 200. The projection plane F9 can bisect the first housing 100, or it can substantially bisect the first housing 100; the portions of the first housing 100 on both sides of the projection plane F9 can be the same or substantially the same. The projection plane F9 can also bisect the connecting member 300, or it can substantially bisect the connecting member 300; the portions of the connecting member 300 on both sides of the projection plane F9 can be the same or substantially the same. Of course, the projection plane F9 can also bisect or substantially bisect the second housing 200. For example... Figure 8 As shown, the second coordinate axis X can be parallel or the same as the thickness direction of the second housing 200.

[0156] In this implementation, the projection curve may include a portion of the projection curve of the connector 300 on the projection plane F9, a portion of the projection curve of the first housing 100 on the projection plane F9, and a portion of the projection curve of the second housing 200 on the projection plane F9.

[0157] In this implementation, such as Figure 8 As shown, the maximum dimension D1 of the ear-clip headphones in the first coordinate axis Y direction can be 26mm to 29mm. Here, the maximum dimension D1 can be located at the connector 300. By setting the maximum dimension D1 of the ear-clip headphones appropriately in the first coordinate axis Y direction, the wearing stability of the ear-clip headphones can be improved, and the size of the connector 300 can also be set appropriately, thereby achieving miniaturization of the connector 300. The maximum dimension D1 can also be 27mm to 28mm, 26mm to 28mm, 27mm to 29mm, etc.

[0158] In this implementation, the maximum size area of ​​the ear clip earphone in the first coordinate axis Y direction can be located at the connector 300; the highest point 340 of the projection curve can be located at the connector 300; the maximum size area of ​​the ear clip earphone in the first coordinate axis Y direction and the highest point 340 of the projection curve can be set back to back, and the highest point 340 and the maximum size area can be realized simultaneously through a part of the connector 300, which can realize the miniaturization of the connector 300.

[0159] In this implementation, the dimension D3 of the region corresponding to the highest point 340 of the projected curve of the connector 300 in the first coordinate axis Y direction can be 2.5mm to 3.5mm. By setting the dimension D3 of the connector 300 in the first coordinate axis Y direction appropriately, it is possible to ensure that the connector 300 provides a suitable clamping force for the first housing 100 and the second housing 200, while also achieving miniaturization of the connector 300. The dimension D3 can also be 2.5mm to 3mm, 3mm to 3.5mm, etc.

[0160] In this implementation, such as Figure 8 As shown, in the coordinate system, the first housing 100 and the second housing 200 can be located on the same side of the second coordinate axis X. The distance D4 between the first housing 100 and the second coordinate axis X can be 0.8mm to 1.3mm. By setting the distance D4 between the first housing 100 and the second coordinate axis X appropriately, the first housing 100 can fit more snugly against the wearer's concha, and the second housing 200 can fit more snugly against the back of the wearer's ear and head, thereby improving wearing stability. The distance D4 can also be 0.9mm to 1.2mm, 1mm to 1.1mm, 1mm to 1.3mm, 0.8mm to 1mm, etc.

[0161] In this implementation, the distance D5 between the highest point 340 of the projected curve and the second housing 200 in the first coordinate axis Y direction can be 9mm to 11mm. By setting a suitable distance D5 between the highest point 340 of the projected curve and the second housing 200 in the first coordinate axis Y direction, both the fit between the connector 300 and the wearer's earlobe and the fit between the second housing 200 and the back of the wearer's ear and head can be improved. The distance D5 can also be 9mm to 10mm, 10mm to 11mm, etc.

[0162] In this implementation, the first housing 100 may include a supporting housing 110 and an elastic housing 120; a sound-generating component 410 may be disposed within the supporting housing 110; the sound-generating component 410 divides the space within the supporting housing 110 into a front cavity 101 and a rear cavity 102; the elastic housing 120 may cover the portion of the supporting housing 110 facing the second housing 200; a deformation space 130 is defined between the elastic housing 120 and the supporting housing 110, and the elastic housing 120 is deformable based on the deformation space 130. The supporting housing 110 and the elastic housing 120 have been described in the above embodiments and will not be repeated here.

[0163] For example, in the coordinate system, the distance D6 between the elastic shell 120 after maximum deformation under pressure in the first coordinate axis Y direction and the highest point 340 of the projected curve can be 9.5mm to 11.5mm. By setting the distance D6 appropriately, both the fit between the connector 300 and the wearer's auricle and the fit between the first shell 100 and the wearer's concha can be improved. The distance D6 can also be 10mm to 11mm, 10.5mm to 11.5mm, 9.5mm to 10.5mm, etc.

[0164] In this implementation, the thickness direction of the second housing 200 can be the same as the direction of the second coordinate axis X. The second housing 200 can include, in the thickness direction, two adjacent half-shells: a first half-shell 210 and a second half-shell 220; the battery 420 can be disposed within the space defined between the first half-shell 210 and the second half-shell 220; and the circuit board 430 can be disposed within the space defined between the first half-shell 210 and the second half-shell 220. The axial direction of the battery 420 is the same as the thickness direction of the second housing 200; and / or, the thickness direction of the circuit board 430 is the same as the thickness direction of the second housing 200. By configuring the second housing 200 as two half-shells, it is convenient to install the battery 420 and the circuit board 430.

[0165] In this implementation, the length N8 of the second housing 200 can be 19mm to 23mm; and / or, the height N6 of the second housing 200 can be 13mm to 17mm; the length N8 and height N6 have been described in the above embodiments and will not be repeated here.

[0166] In some implementations of the embodiments of this disclosure, the ear-clip earphone may include a first housing 100, a sound-generating component 410, a second housing 200, and a connector 300. The sound-generating component 410 may be disposed within the first housing 100; the first end 320 of the connector 300 may be connected to the first housing 100, and the second end 330 of the connector 300 may be connected to the second housing 200; the first housing 100, the connector 300, and the second housing 200 may form a clamping space 510. The first housing 100, the sound-generating component 410, the second housing 200, the connector 300, and the clamping space 510 have been described in the above embodiments, and will not be repeated here.

[0167] In some implementations of the embodiments of this disclosure, such as Figure 11As shown, on the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X. The clamping space 510 forms a projection curve on the coordinate system composed of the first coordinate axis Y and the second coordinate axis X. There is a first intersection point 301 between the connector 300 and the first housing 100 on the projection curve, and a second intersection point 302 between the connector 300 and the second housing 200 on the projection curve. There is a first distance F3 between the highest point 340 of the projection curve and the first intersection point 301, and a second distance between the highest point 340 of the projection curve and the second intersection point 302. The ratio of the first distance F3 to the second distance F4 can be greater than 1 and less than or equal to 2.

[0168] The size design of clip-on earphones often results in poor fit to the wearer's ears, easily causing discomfort. For example, when the earphone structure is worn, a large gap between the C-bridge portion of the earphone structure and the wearer's ear can cause it to wobble, while a small gap can cause it to be pushed up by the wearer's ear, preventing the earphone structure from fitting properly and thus affecting its stability. The clip-on earphone of this application, by setting a more suitable ratio between the first distance F3 and the second distance F4, allows the shape of the connector 300 to better match the shape of the wearer's ear. This improves both the fit of each area of ​​the connector 300 to the wearer's ear and the stability of the clip-on earphone.

[0169] In this implementation, the projection curve and projection plane F9 have already been described in the above embodiments, and will not be repeated here. Figure 11 As shown, the first intersection point 301 can be the intersection of the projected curve of the connector 300 and the projected curve of the first housing 100. The first intersection point 301 can be the minimum value of the projected curve on the second coordinate axis X. Of course, in some other examples, the first intersection point 301 may not be the minimum value of the projected curve on the second coordinate axis X. The second intersection point 302 can be the intersection of the projected curve of the connector 300 and the projected curve of the second housing 200. The second intersection point 302 can be the maximum value of the projected curve on the second coordinate axis X. Of course, as... Figure 11 As shown, the second intersection point 302 may not be the maximum value of the projected curve on the second coordinate axis X. The length of the clamping space 510 on the second coordinate axis X can be basically determined by the first intersection point 301 and the second intersection point 302.

[0170] With the first housing 100 and the second housing 200 essentially determined, the height of the clamping space 510 on the first coordinate axis Y can be roughly determined by the highest point 340. The highest point 340 can be the point where the connector 300 mates with the wearer's auricle. A more suitable position of the highest point 340 can make the highest area of ​​the connector 300 mate more properly with the wearer's auricle, preventing the wearer's auricle from mate with the lower area of ​​the connector 300, and reducing the risk that the lower area is not high enough and will push the connector 300 up. The area of ​​connector 300 between the first intersection point 301 and the highest point 340 can fit with the front of the wearer's ear, and the area of ​​connector 300 between the second intersection point 302 and the highest point 340 can fit with the back of the wearer's ear. By setting the ratio of the first distance F3 and the second distance F4 appropriately, the distance between the highest point 340 and the wearer's ear helix can be reduced in the wearing state, reducing the risk of the ear clip headphones being pushed up, and the fit between connector 300 and the front and back of the wearer's ear can be improved.

[0171] In this implementation, the ratio of the first distance F3 to the second distance F4 can also be 1.7 to 2; and / or, the highest point 340 of the projection curve and the first intersection point 301 form the first line segment F5, the highest point 340 of the projection curve and the second intersection point 302 form the second line segment F6, and the included angle F7 between the first line segment F5 and the second line segment F6 can be 64 degrees to 68 degrees; by setting the included angle F7 appropriately, both the fit between the connector 300 and the front side of the wearer's ear and the fit between the connector 300 and the back side of the wearer's ear can be improved. Here, the ratio of the first distance F3 to the second distance F4 can also be 1.5 to 2, 1.3 to 2, 1.4 to 2, 1.6 to 2, 1.8 to 2, 1.9 to 2, 1.1 to 2, 1.2 to 2, 1.75 to 1.95, etc.

[0172] In this implementation, the first distance F3 can be 17mm to 21mm; and / or, the length of the first inner contour line 303 of the connector 300 between the highest point 340 of the projected curve and the first intersection point 301 can be 19mm to 23mm. By setting the first distance F3 appropriately, both the fit between the connector 300 and the front of the wearer's ear and the fit between the first housing 100 and the wearer's concha can be improved. By setting the length of the first inner contour line 303 appropriately, the fit between each area of ​​the connector 300 and the front of the wearer's ear can be improved. The first distance F3 can also be 18mm to 20mm, 19mm to 21mm, 17mm to 19mm, 18.5mm to 19.5mm, etc. The length of the first inner contour line 303 can also be 20mm to 22mm, 21mm to 23mm, 19mm to 21mm, 21 to 22mm, etc.

[0173] In this implementation, the length of the first inner contour line 303 of the connector 300 between the highest point 340 and the first intersection point 301 of the projection curve has a first ratio to the first distance F3, and the length of the second inner contour line 304 of the connector 300 between the highest point 340 and the second intersection point 302 of the projection curve has a second ratio to the second distance F4. The first ratio can be from 1.05 to 1.12, and the second ratio can be from 1.2 to 1.35; and / or, the first ratio can be less than the second ratio. The first ratio corresponds to the curvature of the first inner contour line 303, and the second ratio corresponds to the curvature of the second inner contour line 304. By setting an appropriate first ratio, the fit between the connector 300 and the front side of the ear can be improved, and by setting an appropriate second ratio, the fit between the connector 300 and the back side of the ear can be improved. The curvature of the back side of the ear is generally greater than that of the front side of the ear. By setting the first ratio to be less than the second ratio, the fit between the connector 300 and the ear can be further improved.

[0174] The first ratio can also be 1.06 to 1.11, 1.07 to 1.1, 1.08 to 1.09, 1.05 to 1.09, 1.09 to 1.12, etc. The second ratio can also be 1.22 to 1.32, 1.24 to 1.3, 1.26 to 1.28, 1.2 to 1.27, 1.27 to 1.35, etc.

[0175] In this implementation, such as Figure 11 As shown, on the projection plane, the surface of the first housing 100 facing the second housing 200 has a first tangent F1, and the highest point 340 of the projection curve is located on the first tangent F1. The highest point 340 of the projection curve and the first intersection point 301 form a first line segment F5, and the included angle F2 between the first line segment F5 and the first tangent F1 can be 31 degrees to 35 degrees. The surface of the first housing 100 facing the second housing 200 is used to mate with the wearer's concha, and the area of ​​the connector 300 corresponding to the first line segment F5 is used to mate with the front of the wearer's ear. By setting the included angle F2 between the first line segment F5 and the first tangent F1 appropriately, both the fit between the connector 300 and the front of the ear and the fit between the first housing 100 and the concha can be improved. At the same time, by making the first tangent F1 of the surface of the first housing 100 facing the second housing 200 pass through the highest point 340, the position of the highest point 340 can have a reference standard, thereby improving the positional accuracy of the highest point 340. Of course, in other examples, the first tangent F1 on the surface of the second housing 200 may not pass through the highest point 340.

[0176] The angle F2 between the first line segment F5 and the first tangent F1 can also be 32 to 34 degrees, 33 to 34 degrees, 32 to 33 degrees, 31 to 33 degrees, 33 to 35 degrees, etc.

[0177] In this implementation, the distance between the first intersection point 301 and the highest point 340 of the projected curve in the second coordinate axis X direction can be greater than the distance between the second intersection point 302 and the highest point 340 of the projected curve in the second coordinate axis X direction; and / or, the highest point 340 of the projected curve in the second coordinate axis X direction can be located closer to the second housing 200. By bringing the highest point 340 closer to the second housing 200, the fit between the highest point 340 and the wearer's ear helix can be improved.

[0178] In this implementation, the thickness direction of the second housing 200 may be the same as the direction of the second coordinate axis X; and / or, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed adjacently; the first half-shell 210 is located on the side closer to the first housing 100, and the second half-shell 220 is located on the side farther from the first housing 100; the ear clip-on earphone may include a battery 420 and a circuit board 430; the battery 420 may be disposed within the space defined between the first half-shell 210 and the second half-shell 220; the circuit board 430 may be disposed within the space defined between the first half-shell 210 and the second half-shell 220; wherein, the axial direction of the battery 420 is the same as the thickness direction of the second housing 200; and / or, the thickness direction of the circuit board 430 is the same as the thickness direction of the second housing 200.

[0179] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 may be located closer to the first housing 100, and the second half-shell 220 may be located farther from the first housing 100; the connector 300 may include a first connecting portion 350 and a second connecting portion 360. The first connecting portion 350 is connected to the side of the first housing 100 opposite to the second half-shell 220; the first connecting portion 350 may have a highest point 340 of its projected curve; the second connecting portion 360 may be connected to both the first connecting portion 350 and the second half-shell 220; wherein, the second connecting portion 360 and the second half-shell 220 may be different parts of a single structural member; or, the second connecting portion 360 and the second half-shell 220 may be different structural members. By setting the highest point 340 at the first connecting portion 350, wearing comfort can be improved, and the discomfort caused by the discontinuity at the connection area of ​​the first connecting portion 350 and the second connecting portion 360 can be reduced.

[0180] In this implementation, on the projection plane, the connector 300 can be recessed at the second intersection point 302 away from the first intersection point 301; and / or, on the projection plane, the second housing 200 has the greatest height at the second intersection point 302, and the height of the second housing 200 towards the connector 300 first increases and then decreases. By recessing the connector 300 at the second intersection point 302 towards the positive direction of the second coordinate axis X, the size of the clamping space 510 in the positive direction of the second coordinate axis X can be increased; interference between the connector 300 and the wearer's ear can be prevented, improving the fit between the second housing 200 and the wearer's ear; by setting the second intersection point 302 as the highest point of the second housing 200, the risk of interference between other areas of the second housing 200 and the wearer's ear can be reduced, thereby improving the fit between the second housing 200 and the wearer's ear.

[0181] In some implementations of the embodiments of this disclosure, such as Figure 12 As shown, on the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X. The clamping space 510 forms a projection curve on the coordinate system composed of the first coordinate axis Y and the second coordinate axis X. There is a first intersection point between the connector 300 and the first housing 100 on the projection curve. There is a first distance F3 between the highest point 340 of the projection curve and the first intersection point 301. The first distance F3 can be 17mm to 21mm.

[0182] The inventors discovered that the size design of clip-on headphones is poorly adapted to the wearer's ear, easily causing discomfort. For example, when the headphone structure is worn, if the C-bridge of the headphone structure is set too long, the corresponding part on the front of the wearer's ear is prone to contacting the helix of the ear and pushing up the headphone structure. If the C-bridge of the headphone structure is set too short, the corresponding part on the back of the ear is prone to contacting the helix of the ear and pushing up the headphone structure, thus affecting the wearing stability of the headphone structure. However, the clip-on headphone of this application, by setting a more reasonable first distance F3 between the highest point 340 of the projection curve and the first intersection point 301, can reduce the distance between the highest point 340 of the projection curve and the helix of the wearer when worn, reducing the risk of the connector 300 being pushed up by the wearer's helix, thereby improving the wearing stability of the clip-on headphone.

[0183] The first intersection point 301, the highest point 340, and the projection plane F9 have been described in the above embodiments, and will not be repeated here. The first distance F3 can also be 18mm to 20mm, 17mm to 19mm, 19mm to 21mm, 18mm to 19mm, etc.

[0184] In this implementation, on the projection plane, the first housing 100 and the second housing 200 can have a shortest connecting line H2; the distance between the midpoint of the shortest connecting line H2 and the target point 370, which is furthest from the connector 300, and the highest point 340 of the projection curve can be less than or equal to 2.5 mm; and / or, the distance H3 between the midpoint of the shortest connecting line H2 and the highest point 340 of the projection curve can be 12 mm to 16 mm. By setting the highest point 340 closer to the target point 370, the highest point 340 can be closer to the wearer's ear helix in the wearing state, thereby improving the fit of the ear clip headphones. By setting the distance H3 between the midpoint of the shortest connecting line H2 and the highest point 340 of the projection curve more appropriately, the highest point 340 can better match the wearer's ear helix, improving the fit of the highest point 340 to the wearer's ear helix.

[0185] Of course, the distance between the target point 370 and the highest point 340 of the projected curve can also be less than or equal to 2mm, 1.5mm, 1mm, 0.5mm, etc. Alternatively, the distance between the target point 370 and the highest point 340 of the projected curve can be zero; in other words, the highest point 340 can be the point where the distance between the midpoint of the shortest connecting line H2 and the connector 300 is greatest. The distance H3 can also be 13mm to 15mm, 13mm to 14mm, 14mm to 15mm, 12mm to 14mm, 14mm to 16mm, etc.

[0186] In this implementation, on the projection plane, the first housing 100 and the second housing 200 can have a shortest connecting line H2. The midpoint of the shortest connecting line H2 and the highest point 340 of the projection curve form a reference line H4. The highest point 340 of the projection curve and the first intersection point 301 form a first line segment F5. The included angle H6 between the reference line H4 and the first line segment F5 can be 36 degrees to 40 degrees. By setting the included angle H6 appropriately, the fit of the ear clip headphones can be improved. The included angle H6 can also be 37 degrees to 39 degrees, 37 degrees to 38 degrees, 38 degrees to 39 degrees, 36 degrees to 38 degrees, 38 degrees to 40 degrees, etc.

[0187] In this implementation, the first housing 100 and the second housing 200 can have a shortest connecting line H2.

[0193] In this implementation, on the projection plane, the connector 300 and the second housing 200 have a second intersection point 302 on the projection curve. The height of the second housing 200 at the second intersection point 302 can be maximized. The height of the second housing 200 towards the connector 300 can first increase and then decrease to improve the fit between the second housing 200 and the wearer's ear; and / or, the first housing 100 and the second housing 200 have a shortest connection line H2. In the height direction of the second housing 200, the shortest connection line H2 intersects with the first housing 100.

[0194] In some implementations of the embodiments of this disclosure, such as Figure 13 As shown, on the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X. The clamping space 510 forms a projection curve on the coordinate system composed of the first coordinate axis Y and the second coordinate axis X. The distance K1 between the highest point 340 of the projection curve and the first region 103 of the first housing 100 can be 12.5mm to 16.5mm. The distance H1 between the first region 103 of the first housing 100 and the second region 202 of the second housing 200 can be the minimum distance between the first housing 100 and the second housing 200.

[0195] The inventors discovered that the size design of clip-on headphones is poorly adapted to the wearer's ears, easily causing discomfort. For example, the clamping areas between the two shells of the headphone structure exert a clamping force on the wearer's ears. If the distance between the clamping area and the C-bridge of the headphone structure is large, the C-bridge is prone to shifting, resulting in unstable wearing. The clip-on headphones of this application, by setting a more reasonable distance K1 between the highest point 340 of the projection curve and the first area 103 of the first shell 100, can reduce the shift of the connector 300 at the highest point 340 during wearing, thereby improving the wearing stability of the clip-on headphones.

[0196] In this implementation, the first region 103 and the second region 202 are used to clamp the wearer's ear. The clamping force between the first region 103 and the second region 202 is used to stabilize the ear clip headphones. The first region 103 and the second region 202 can be understood as the fulcrum of the ear clip headphones on the wearer's ear. The high point region 310 corresponding to the highest point 340 of the connector 300 is relatively far from the first region 103. During the wearing process, the high point region 310 is prone to shift relative to the first region 103. The shift of the high point region 310 has a significant impact on the overall wearing stability of the ear clip headphones. By setting the distance K1 appropriately, the shift of the high point region 310 relative to the first region 103 can be reduced, thereby greatly improving the wearing stability of the ear clip headphones. K1 can also be 13.5mm to 15.5mm, 12.5mm to 14.5mm, 14.5mm to 16.5mm, 13.5mm to 14.5mm, etc.

[0197] In this implementation, the distance K2 between the highest point 340 of the projection curve and the second region 202 can be from 11.5mm to 15.5mm. By setting the distance K2 appropriately, the offset of the high point region 310 relative to the second region 202 can be reduced, thereby greatly improving the wearing stability of the ear clip headphones. The distance K2 can also be 12.5mm to 14.5mm, 11.5mm to 13.5mm, 13.5mm to 15.5mm, 12.5mm to 13.5mm, 13.5mm to 14.5mm, etc.

[0198] In this implementation, a first line K3 can be formed between the highest point 340 of the projection curve and the first region 103 on the projection plane, and a second line K4 can be formed between the highest point 340 of the projection curve and the second region 202. The included angle K5 between the first line K3 and the second line K4 can be 12 to 16 degrees. By setting the included angle K5 appropriately, the force on the first region 103 and the second region 202 can be more even, improving wearing comfort. The included angle K5 can also be 13 to 15 degrees, 12 to 14 degrees, 14 to 16 degrees, 14 to 15 degrees, 13 to 14 degrees, etc.

The relevant characteristics of the shortest connecting line H2 have been described in the above embodiments and will not be repeated here.

The distance between the first intersection point 301 and the highest point 340 of the projection curve in the second coordinate axis X direction can be greater than the distance between the second intersection point 302 and the highest point 340 of the projection curve in the second coordinate axis X direction, so as to improve the fit between the connector 300 and the ear.

The first connecting portion 350 and the second connecting portion 360 have been described in the above embodiments and will not be repeated here.

[0204] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 may be located closer to the first housing 100, and the second half-shell 220 may be located farther from the first housing 100; the ear clip-on earphone may include a battery 420 and a circuit board 430.

[0205] In this implementation, in the height direction of the second housing 200, the distance between the first housing 100 and the second housing 200 can first decrease and then increase in the direction near the highest point 340 of the projection curve to improve wearing comfort; and / or, in the height direction of the second housing 200, the first region 103 can be located on the side of the first housing 100 near the highest point 340 of the projection curve, and the second region 202 can be located on the side of the second housing 200 near the highest point 340 of the projection curve to improve wearing stability.

[0206] In some implementations of the embodiments of this disclosure, such as Figure 14 As shown, on the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X.

The distance H1 between the first region 103 of the first housing 100 and the second region 202 of the second housing 200 is the minimum distance between the first housing 100 and the second housing 200.

[0207] The inventors discovered that the size design of clip-on earphones is poorly adapted to the wearer's ears, easily causing discomfort. For example, the sound-generating structure of the earphone is designed to fit into the wearer's concha, and the clamping area of ​​the sound-generating structure is used to hold the sound-generating structure in place within the wearer's concha. If the angle between the clamping area and the front side of the C-bridge of the earphone structure is large, the clamping force of the sound-generating structure is too small and it is prone to shifting. If the angle between the clamping area and the front side of the C-bridge of the earphone structure is small, the clamping force of the sound-generating structure is too large and can cause pain to the wearer. However, the clip-on earphone of this application, by setting a more reasonable angle K6, can achieve a suitable clamping force at the first housing 100 and prevent the connector 300 from shifting, thereby balancing the wearing stability and comfort of the clip-on earphone.

[0208] In this implementation, the included angle K6 can be 30 to 32 degrees, 29 to 31 degrees, 31 to 33 degrees, 30 to 31 degrees, 31 to 32 degrees, etc.

[0214] In this implementation, the connector 300 and the second housing 200 on the projection curve have a second intersection point 302. The distance between the first intersection point 301 and the highest point 340 of the projection curve in the second coordinate axis X direction can be greater than the distance between the second intersection point 302 and the highest point 340 of the projection curve in the second coordinate axis X direction.

The first connecting portion 350 and the second connecting portion 360 have been described in the above embodiments and will not be repeated here.

[0216] In this implementation, the second housing 200 may include, in the thickness direction, a first half-shell 210 and a second half-shell 220 disposed opposite to each other; the first half-shell 210 is located near the first housing 100, and the second half-shell 220 is located away from the first housing 100; the ear clip-on earphone may include a battery 420 and a circuit board 430. The battery 420 may be disposed within the space defined by the first half-shell 210 and the second half-shell 220; the circuit board 430 may be disposed within the space defined by the first half-shell 210 and the second half-shell 220; wherein, the axial direction of the battery 420 is the same as the thickness direction of the second housing 200; and / or, the thickness direction of the circuit board 430 is the same as the thickness direction of the second housing 200.

[0217] In this implementation, in the height direction of the second housing 200, the distance between the first housing 100 and the second housing 200 first decreases and then increases in the direction approaching the highest point 340 of the projection curve; and / or, the first housing 100 and the second housing 200 have a shortest connecting line H2. In the height direction of the second housing 200, the first region 103 corresponding to the shortest connecting line H2 and the first housing 100 is located on the side of the first housing 100 near the highest point 340 of the projection curve, and the second region 202 corresponding to the shortest connecting line H2 and the second housing 200 is located on the side of the second housing 200 near the highest point 340 of the projection curve. The positions of the first region 103 and the second region 202 have been described in the above embodiments and will not be repeated here.

[0218] In some implementations of the embodiments of this disclosure, such as Figure 15As shown, on the projection plane F9 that bisects the first housing 100 and the connector 300, the height direction of the second housing 200 is taken as the first coordinate axis Y, and the direction perpendicular to the first coordinate axis Y and passing through the lowest point of the second housing 200 is taken as the second coordinate axis X. The clamping space 510 forms a projection curve on the coordinate system composed of the first coordinate axis Y and the second coordinate axis X. There is a first intersection point 301 between the connector 300 and the first housing 100 on the projection curve, and a second intersection point 302 between the connector 300 and the second housing 200 on the projection curve. There is a first inner contour line 303 between the highest point 340 of the projection curve and the first intersection point 301, and a second inner contour line 304 between the highest point 340 of the projection curve and the second intersection point 302. The curvature of the first inner contour line 303 is less than the curvature of the second inner contour line 304.

[0219] The inventors discovered that the size design of clip-on earphones is poorly adapted to the wearer's ear, easily causing discomfort. For example, an improperly shaped C-bridge in the earphone structure can easily cause the C-bridge to have a large gap with the wearer's ear, making it prone to wobbling, or it can be pushed up and shifted by the wearer's ear. The clip-on earphone of this application, by having a curvature of the first inner contour line 303 that is less than the curvature of the second inner contour line 304, allows the shape of the connector 300 to better match the shape of the wearer's ear. This improves both the fit between the connector 300 and the front and back of the wearer's ear, thereby enhancing the stability and comfort of the clip-on earphone.

[0220] In this implementation, a first inner contour line 303 and a second inner contour line 304 are located on the connector 300. The first inner contour line 303 corresponds to the front side of the wearer's ear, and the second inner contour line 304 corresponds to the back side of the wearer's ear. The shape of the front side of the wearer's ear is relatively flatter than the shape of the back side of the wearer's ear. By making the curvature of the first inner contour line 303 less than the curvature of the second inner contour line 304, the shape of the connector 300 can better match the shape of the wearer's ear.

The first connecting portion 350 may be connected to the side of the first housing 100 opposite to the second half-shell 220; the first connecting portion 350 has a highest point 340 of its projection curve; the second connecting portion 360 may be connected to both the first connecting portion 350 and the second half-shell 220; wherein, the second connecting portion 360 and the second half-shell 220 are different parts of a single structural member; or, the second connecting portion 360 and the second half-shell 220 are different structural members. The first connecting portion 350 and the second connecting portion 360 have been described in the above embodiments and will not be repeated here.

[0229] In this implementation, on the projection plane, the connector 300 can be recessed towards the side away from the first intersection point 301 at the second intersection point 302; and / or, on the projection plane, the second housing 200 has the greatest height at the second intersection point 302, and the height of the second housing 200 towards the connector 300 can first increase and then decrease. The features of the second housing 200 at the second intersection point 302 have been described in the above embodiments and will not be repeated here.

[0230] In some implementations of the embodiments of this disclosure, such as Figure 6As shown, the clip-on earphone may include a first housing 100, a sound-generating component 410, a second housing 200, and a connector 300. The first housing 100 may include a support housing 110 and an elastic housing 120. The elastic housing 120 may enclose the support housing 110; the sound-generating component 410 may be disposed within the support housing 110; the sound-generating component 410 divides the space within the support housing 110 into a front cavity 101 and a rear cavity 102; the side of the sound-generating component 410 with a diaphragm 411 is located on the front cavity 101 side, and the side of the sound-generating component 410 facing away from the diaphragm 411 is located on the rear cavity 102 side; the second housing 200 may have a mounting through hole 203; a battery 420 and a circuit board 430 are disposed within the second housing 200; a charging component 450 is disposed at the mounting through hole 203, and the circuit board 430 is electrically connected to the sound-generating component 410, the battery 420, and the charging component 450 respectively; the connector 300... The first end 320 is connected to the first housing 100, and the second end 330 of the connector 300 is connected to the second housing 200; wherein, in the height direction of the second housing 200, the connector 300 has a high point region 310 that is at the greatest distance from the second housing 200, and the elastic shell 120 facing the second housing 200 includes a first end close to the high point region 310 and a second end away from the high point region 310; the first end 126 of the elastic shell 120 has a first deformation amount M1 in the direction away from the second housing 200, and the second end 127 of the elastic shell 120 has a second deformation amount M2 in the direction away from the second housing 200; the first deformation amount M1 can be greater than the second deformation amount M2.

[0231] Ear clip-on headphones often have poor fit to the wearer's ears, leading to discomfort. For example, if the sound-generating and power-generating structures are designed to hold the wearer's ear, an improperly sized side of the sound-generating structure facing the power-generating structure can cause it to wobble or cause pain when wearing them. The ear clip earphone disclosed herein includes a first end near the high point region 310 and a second end away from the high point region 310 on the side of the elastic shell 120 facing the second shell 200. The first end 126 of the elastic shell 120 has a first deformation amount M1 in the direction away from the second shell 200, and the second end 127 of the elastic shell 120 has a second deformation amount M2 in the direction away from the second shell 200. The first deformation amount M1 is greater than the second deformation amount M2, which allows the first end 126 of the elastic shell 120 to adapt to the shape of the wearer's concha cavity with a larger deformation amount, thereby increasing the fit and comfort between the first end 126 of the elastic shell 120 and the wearer's concha cavity. By setting the deformation amount of the second end 127 of the elastic shell 120 to be relatively small, the clamping force and wearing stability between the second end 127 of the elastic shell 120 and the wearer's concha cavity can be increased.

[0232] In this implementation, the values ​​of the first deformation amount M1 and the second deformation amount M2 are not limited. For example, the first deformation amount M1 can be 1 mm to 3 mm; the second deformation amount M2 can be 0.3 mm to 1.5 mm; and / or, from the first end 126 to the second end 127 of the elastic shell 120, the deformation amount of the elastic shell 120 in the direction away from the second shell 200 can gradually decrease to improve wearing stability, reduce the pressure of the first side of the first shell 100 on the wearer's concha cavity, and improve wearing comfort. In other examples, from the first end 126 to the second end 127 of the elastic shell 120, the deformation amount of the elastic shell 120 in the direction away from the second shell 200 can also first decrease, then increase, and then decrease again. The first deformation amount M1 can also be 1.5 mm to 2.5 mm, 1 mm to 2 mm, 2 mm to 3 mm, 1.5 mm to 2 mm, 2 mm to 2.5 mm, etc. The second deformation amount M2 can also be 0.6mm to 1.2mm, 0.8mm to 1mm, 0.9mm to 1.5mm, 0.3mm to 0.9mm, 0.6mm to 0.9mm, etc.

[0233] In this implementation, such as Figure 16 As shown, in the length direction of the second shell 200, the length of the first end 126 of the elastic shell 120 is less than the length of the second end 127 of the elastic shell 120. By setting a larger first deformation amount M1 at the shorter first end and a smaller second deformation amount M2 at the longer second end, both wearing comfort and wearing stability can be improved. In other words, by setting a larger first deformation amount M1 at the relatively smaller first end and a smaller second deformation amount M2 at the relatively larger second end, it is easier to adapt to the shape of the wearer's concha, while improving wearing stability and comfort.

[0234] In this implementation, the support shell 110 may include a first end and a second end. The first end 113 of the support shell 110 may correspond to the position of the first end 126 of the elastic shell 120, and there may be a first deformation amount M1 between the first end 113 of the support shell 110 and the first end 126 of the elastic shell 120. The second end 114 of the support shell 110 may correspond to the position of the second end 127 of the elastic shell 120, and there may be a second deformation amount M2 between the second end 114 of the support shell 110 and the second end 127 of the elastic shell 120.

[0237] In this implementation, the second housing 200 may include one end close to the first housing 100 and another end away from the first housing 100 in the thickness direction.

Of course, in other examples, the thickness N1 can be less than 8 mm or greater than 13 mm; the height N6 can be less than 13 mm or greater than 17 mm.

The distance H1 between the first region 103 of the first housing 100 and the second region 202 of the second housing 200 is the minimum distance between the first housing 100 and the second housing 200.
