Detailed Implementation

[0033] 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.

[0034] 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.

[0035] The following combination Figures 1 to 27 The clip-on headphones and headphone system described in the embodiments of this disclosure will be described in detail.

[0036] This disclosure describes an ear-clip earphone, which may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410. The first housing 100 may include: a support shell 110 and an elastic shell 120; or, the first housing 100 may include: a support shell 110. The sound-generating assembly 410 may be disposed within the support shell 110 by means of adhesive bonding, snap-fitting, welding, etc.; the sound-generating assembly 410 divides the space within the support shell 110 into a front cavity 101 and a rear cavity 102, and a first sound outlet 111 communicates with the front cavity 101; the side of the sound-generating assembly 410 with the diaphragm 411 is located on the front cavity 101 side, and the side of the sound-generating assembly 410 opposite to the diaphragm 411 is located on the rear cavity 102 side, such as... Figure 3 As shown, the first end 310 of the connector can be connected to the support shell 110 by means of bonding, snap-fitting, welding, etc., and the second end 320 of the connector can be connected to the second shell 200 by means of bonding, snap-fitting, welding, etc.

[0037] This disclosure describes an earphone system, including an earphone case and clip-on earphones according to this disclosure. The earphone case may include a storage slot for storing the clip-on earphones.

[0038] like Figure 1 As shown, the first housing 100, the second housing 200, and the connector 300 can form a clamping space 510, with a clamping gap 520 between the first housing 100 and the second housing 200. In the wearing state, the wearer's earlobe side can be located within the clamping space 510, and part of the wearer's ear can be located within the clamping gap 520. The first housing 100 can be located in front of the wearer's ear, and the second housing 200 can be located behind the wearer's ear. By appropriately setting the clamping gap 520, the ear clip-on headphones can be stably worn on the wearer's ear.

[0039] In the disclosed embodiments, the second housing 200 can be used to accommodate structural components of the ear clip-on headphones. In some examples, such as Figure 3 As shown, the clip-on earphone may include a battery 420 and a circuit board 430. The battery 420 and circuit board 430 may be disposed within the second housing 200 by means of adhesive bonding, snap-fitting, soldering, or other methods. Of course, in other examples, at least one of the battery 420 and circuit board 430 may also be disposed within the first housing 100. This disclosure does not limit this.

[0040] In some examples, such as Figure 1 and Figure 2As shown, the ear-clip headphones may have a button 440, which may be disposed in the second housing 200, and the button 440 may be used to control the ear-clip headphones. In some other examples, the ear-clip headphones may include a charging component 450, which may be disposed in the second housing 200, and the charging component 450 may be used to charge the ear-clip headphones.

[0041] In some examples, such as Figure 1 and Figure 9 As shown, one end of the second housing 200 in the height direction can be connected to the second end 320 of the connector, and the second housing 200 in the width direction can be disposed opposite to the first mating part 121.

[0042] It should be noted that the height and width directions in this disclosure can refer to the height and width directions of the second housing 200, such as... Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown.

[0043] In the disclosed embodiments, 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.

[0044] The connector 300 can be elastic, allowing the clamping gap between the first housing 100 and the second housing 200 to be adjusted based on the elasticity of the connector 300, thereby making it easier to wear the earbuds to a more suitable position during use. 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.

[0045] In some examples, such as Figure 3 As shown, the ear clip-on headphones may include a connecting cable 460, which can be electrically connected to the circuit board 430 and the sound-generating component 410 respectively.

[0046] In the disclosed embodiments, the structure of the sound-generating component 410 is not limited. For example, the sound-generating component 410 can be a speaker or other structure capable of emitting sound.

[0047] In the disclosed embodiments, the rigidity of the support shell 110 can be relatively high. The material of the support shell 110 is not limited. For example, the material of the support shell 110 may include plastic, etc.

[0048] The dimensions of the support shell 110 are not limited. The dimension of the support shell 110 in the first direction can be larger than the dimension of the support shell 110 in the second direction, and the dimension of the support shell 110 in the first direction can be larger than the dimension of the support shell 110 in the third direction. The first direction can be perpendicular to the second direction and the third direction, respectively. The first direction can be the direction with the largest dimension of the support shell 110; in other words, the first direction can be the length direction of the support shell 110.

[0049] In some examples, the maximum dimension of the support shell 110 in the first direction can be 16mm to 17mm, 15mm to 18mm, 16.5mm to 18mm, 15mm to 16.5mm, etc.

[0050] When worn, the support shell 110 is basically or approximately matched to the width of the wearer's concha in the first direction. In other words, the size of the support shell 110 in the first direction is set based on the width of the wearer's concha. Setting the size of the support shell 110 in the first direction relatively large allows the first shell 100 to be closer to the ear canal, effectively shortening the distance from the sound outlet to the ear canal, significantly reducing audio leakage, improving low-frequency texture and overall sound quality, to meet the usage needs in noisy environments such as airplane cabins and subways; setting the size of the support shell 110 in the first direction relatively small allows the first shell 100 to be further away from the ear canal, increasing the amount of external sound entering the ear canal, to meet the needs of open scenarios such as sports and office work where external information needs to be perceived.

[0051] In some examples, the maximum dimension of the support shell 110 in the first direction is used to match the width of the wearer's concha; the maximum dimension of the support shell 110 in the first direction and the width of the wearer's concha can be substantially the same as or close to each other; or, the difference between the maximum dimension of the support shell 110 in the first direction and the width of the wearer's concha can be relatively appropriate to accommodate the distance between the first sound outlet and the ear canal to meet the needs of different audio effects. For example, the difference between the maximum dimension of the support shell 110 in the first direction and the width of the wearer's concha can be less than or equal to 5mm, 4mm, 3mm, 2mm, 1mm, etc. As another example, the difference between the width of the wearer's concha and the maximum dimension of the support shell 110 in the first direction can be less than or equal to 5mm, 4mm, 3mm, 2mm, 1mm, etc. This disclosure does not limit this.

[0052] Here, the width of the concha can be the width between the wearer's tragus and the wearer's antihelix, such as... Figure 27As shown; wherein, the direction of the width of the concha can be parallel to the wearer's horizontal plane, or the angle F between the direction of the width of the concha and the wearer's horizontal plane can be less than or equal to 10 degrees; or the angle F between the direction of the width of the concha and the wearer's horizontal plane can be less than or equal to 8 degrees; or the angle F between the direction of the width of the concha and the wearer's horizontal plane can be less than or equal to 5 degrees; or the angle F between the direction of the width of the concha and the wearer's horizontal plane can be less than or equal to 2 degrees, etc.

[0053] In some examples, such as Figure 9 As shown, the support shell 110 may include a first half-shell 103 and a second half-shell 104. The first half-shell 103 can be connected to the first end 310 of the connector by means of bonding, snap-fitting, welding, etc.; the second half-shell 104 can be connected to the first half-shell 103 by means of bonding, snap-fitting, welding, etc., and has a first sound outlet 111; the first half-shell 103 and the second half-shell 104 can be arranged opposite to each other in a second direction, and the outer contours of the first half-shell 103 and the second half-shell 104 can have a dividing interface P, and the first direction and the dividing interface P can be parallel or substantially parallel; or, the angle between the first direction and the dividing interface P can be less than or equal to 2 degrees, 1 degree, etc. By dividing the support shell 110 into the first half-shell 103 and the second half-shell 104 at a relatively large size, it is convenient to manufacture the first half-shell 103 and the second half-shell 104, and also convenient to install the sound-generating component 410, etc.

[0054] In this embodiment, the shape of the elastic shell 120 can match the shape of the physiological curvature of the human concha. For example, the outer surface of the elastic shell 120 can be modeled in three dimensions to mimic the physiological curvature of the human concha, thereby increasing the contact area and fit between the elastic shell 120 and the inner wall of the concha. Simultaneously, because the elastic shell 120 can further adapt to the shape of the concha through elastic deformation, it can further increase the contact area, fit, and static friction between the elastic shell 120 and the inner wall of the concha, suppressing rotation and slippage of the first shell 100, improving the wearing stability of the first shell 100, and reducing the risk of the first shell 100 causing pain or discomfort to the wearer upon contact with the ear.

[0055] The elastic shell 120 can be wrapped around the support shell 110. The rigidity of the support shell 110 can be greater than that of the elastic shell 120, so that the relatively rigid support shell 110 can support and protect the sound-generating components 410, etc., while the relatively soft elastic shell 120 can improve the wearing comfort and stability of the ear clip-on headphones. The material of the elastic shell 120 can be soft silicone, rubber, etc. In some examples, the Shore hardness of the elastic shell 120 can be 20A to 30A, 20A to 25A, 25A to 30A, etc. A suitable hardness range can produce deformation under extremely low pressure and balance the conformity and support of deformation.

[0056] The area of ​​the support shell 110 enclosed by the elastic shell 120 is not limited. For example, the area of ​​the support shell 110 enclosed and covered by the elastic shell 120 can be larger than the area of ​​the support shell 110 in the exposed state.

[0057] In some examples, the resilient shell 120 may have a second sound outlet 126. The second sound outlet 126 of the resilient shell 120 is located outside and communicates with the first sound outlet 111. The portion of the resilient shell 120 located around the second sound outlet 126 contacts the wearer's ear, which can improve the wearing comfort and fit of the clip-on headphones at the second sound outlet 126.

[0058] The dimensions of the elastic shell 120 are not limited. For example, the dimension of the elastic shell 120 in the first direction can be larger than the dimension of the elastic shell 120 in the second direction. The dimension of the elastic shell 120 in the first direction can be larger than the dimension of the elastic shell 120 in the third direction. In other words, the dimension of the elastic shell 120 in the first direction is the largest. The first direction of the elastic shell 120 can also be the length direction of the elastic shell 120.

[0059] In some examples, the maximum dimension of the resilient shell 120 in the first direction can be 17mm to 28mm, 12mm to 15mm, 15mm to 19mm, 19mm to 24mm, 24mm to 28mm, etc.

[0060] The elastic shell 120 can be directly fixed to the outside of the support shell 110 by means of bonding, snap-fitting, welding, etc. Here, the elastic shell 120 is a non-removable setting. Of course, the elastic shell 120 can also be detachably set outside the support shell 110 by means of snap-fitting, sleeve, etc., so as to facilitate the maintenance and replacement of the elastic shell 120.

[0061] In some examples, the elastic shell 120 can be cap-shaped, constricted, bag-shaped, etc. The elastic shell 120 can be fitted onto the outside of the support shell 110 by increasing the entrance due to its elasticity; at the same time, since the elastic shell 120 is elastic, the position of the elastic shell 120 covering the support shell 110 can be adjusted so that the second sound outlet 126 is located outside the first sound outlet 111 and communicates with the first sound outlet 111; here, the entrance of the elastic shell 120 can be located on the periphery of the connection area between the support shell 110 and the first end 310 of the connector.

[0062] The number of elastic shells 120 is not limited. For example, the number of elastic shells 120 can be at least two, at least three, at least four, at least five, etc. The elastic shells 120 can be the same or different.

[0063] In some examples, at least two resilient shells 120 may include a first resilient shell 1201, a second resilient shell 1202, a third resilient shell 1203, and a fourth resilient shell 1204, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown. The sizes of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can increase sequentially. Different wearers can adapt the first shell 100 to different sizes of concha by replacing the elastic shell 120 with different sizes or by not setting the elastic shell 120. Alternatively, the same wearer can adjust the distance between the first shell 100 and the wearer's ear canal, the tightness of the fit with the ear canal, etc., by replacing the elastic shell 120 with different sizes or by not setting the elastic shell 120, thereby forming different modes of headphones such as open-back headphones, semi-in-ear headphones, and fully in-ear headphones.

[0064] Here, the dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can be increased sequentially in the first direction, the second direction, and the third direction to accommodate different concha widths, concha depths, concha heights, etc.

[0065] Here, the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can directly contact and cooperate with the support shell 110 of the same size by setting different thicknesses, or they can cooperate with the support shell 110 by having different gaps. When the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 have gaps with the support shell 110 to form deformation spaces, when the elastic shell 120 is inserted into the concha cavity, these deformation spaces will deform differently according to the pressure at the contact point, adaptively conforming to the irregular inner wall of the concha cavity or gently sealing the ear canal opening, thereby increasing the contact area, improving the wearing stability, greatly reducing the compression of sensitive areas, and significantly improving the comfort of wearing for a long time.

[0066] Here, when the ear clip-on headphones form a semi-in-ear or fully in-ear headphone, the ear clip-on headphones can also use the sound picked up by the first pickup element 610 and the second pickup element 620 for noise reduction, thereby further increasing the possible headphone modes that the ear clip-on headphones can form and greatly improving the adaptability of the ear clip-on headphones.

[0067] In some examples, a deformation space may exist between the elastic shell 120 and the supporting shell 110. The wall thickness of the deformation space region of the elastic shell 120 can be 0.4mm to 0.6mm, 0.4mm to 0.5mm, 0.5mm to 0.6mm, etc. By setting the wall thickness of the deformation space region of the elastic shell 120 to a relatively appropriate level, the deformation capacity of the elastic shell 120 can be improved, as can its support and low-rebound characteristics. This also avoids excessive and continuous pressure on the soft tissue of the auricle. Of course, in other examples, there may not be a deformation space between the elastic shell 120 and the supporting shell 110.

[0068] In some examples, the resilient shell 120 may be surface treated. For example, the outer surface of the resilient shell 120 may be sprayed with a nano-scale skin-friendly coating to further reduce the surface friction coefficient, bring a silky touch, and eliminate the feeling of foreign objects.

[0069] In some examples, the shape of the elastic shell 120 can match the shape of the wearer's concha. Here, the shape of the elastic shell 120 can be the same as or substantially the same as the shape of the wearer's concha. By making the shape of the elastic shell 120 the same as or substantially the same as the shape of the wearer's concha, the wearing stability of the elastic shell 120 in the concha can be improved, preventing the elastic shell 120 from reversing or moving in the concha.

[0070] In some examples, such as Figure 1 As shown, the elastic shell 120 may include a first mating part 121 and a second mating part 122 disposed opposite to each other in the first direction. The second mating part 122 may have a second sound outlet 126 to improve the wearing comfort of the ear clip headphones at the second sound outlet 126. There may be a clamping gap 520 between the first mating part 121 and the second shell 200. By clamping the wearer's ear with the elastic first mating part 121, the wearing comfort can be improved and the risk of the ear clip headphones hurting the wearer's ear can be reduced.

[0071] Here, the second mating part 122 can be used to face the wearer's ear canal side. By having the elastic second mating part 122 facing the wearer's ear canal side, the wearing comfort of the ear clip-on headphones on the wearer's ear canal side can be improved, and the contact area and sealing between the second mating part 122 and the wearer's ear canal side can be adjusted when the size of the second mating part 122 is relatively large.

[0072] Here, the first mating part 121 can be in contact with the support shell 110, or there can be a gap. For example, there can be a first deformation space 131 between the first mating part 121 and the support shell 110. The deformation of the first mating part 121 based on the first deformation space 131 can improve the fit between the first mating part 121 and the wearer's ear, thereby further improving the stability and comfort of wearing.

[0073] Here, the second mating part 122 can be in contact with the support shell 110, or there can be a gap. For example, a second deformation space 132 can be provided between the second mating part 122 and the support shell 110. The deformation of the second mating part 122 based on the second deformation space 132 can improve the fit between the second mating part 122 and the wearer's ear canal side, thereby further improving the stability and comfort of wearing. At the same time, different fits between the second mating part 122 and the wearer's ear canal side result in different sounds entering the wearer's ear canal through the second sound outlet 126. The second mating part 122 with a relatively good fit can form a fully in-ear headphone or a semi-in-ear headphone, thereby enabling the ear clip-on headphone to be converted into an in-ear headphone.

[0074] In some examples, such as Figure 4 and Figure 15 As shown, the first extending direction Q of the second sound outlet 126 may have a first included angle K1 with the first direction. The value of the first included angle K1 is not limited. For example, the first included angle K1 can be 35 degrees to 40 degrees, 35 degrees to 38 degrees, 38 degrees to 40 degrees, etc.

[0075] Here, the first direction can be the length direction of the support shell 110 with the largest dimension. Of course, the first direction can also be parallel to the interface P; or, the angle between the first direction and the interface P can be less than or equal to 2 degrees, 1 degree, etc.

[0076] Here, as Figure 15 and Figure 16 As shown, the elastic shell 120 may include a first inner surface 129 disposed opposite to the first outer end face 116 surrounding the first sound outlet 111; the first inner surface 129 may be perpendicular or substantially perpendicular to the first extension direction Q, and the first outer end face 116 and the first inner surface 129 may be parallel or substantially parallel.

[0077] Here, the extension direction of the first sound outlet 111 can be a first extension direction Q; in other words, the extension direction of the first sound outlet 111 and the first extension direction Q of the second sound outlet 126 can be the same. Of course, in other examples, the first extension direction Q of the second sound outlet 126 can also be different from the extension direction of the first sound outlet 111.

[0078] Here, as Figure 15 and Figure 16As shown, the clip-on earphone may further include a first shielding member 710 and a second shielding member 720. The first shielding member 710 and the second shielding member 720 may be located between the first outer end face 116 and the first inner surface 129. The first shielding member 710 may be located on the first inner surface 129. The material of the first shielding member 710 may be metal, plastic, etc., and the first shielding member 710 may have at least two through holes to allow audio to be transmitted through the through holes. The second shielding member 720 may be located on the side of the first outer end face 116, and the second shielding member 720 may be made of fabric mesh, etc.

[0079] In some examples, such as Figure 7 As shown, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first outer surface 113 is oriented towards the bottom of the wearer's concha cavity; in the wearing state, at least a portion of the second outer surface 114 is exposed, and one end of the outer side surface 115 in the first direction may have a first sound outlet 111; the second direction is perpendicular to the first direction; an elastic shell 120 is wrapped around at least a portion of the first outer surface 113 and the outer side surface 115; the first end 310 of the connector is connected to the second outer surface 114; wherein, the shape of the area adjacent to the elastic shell 120 and the first outer surface 113 matches the shape of the bottom of the wearer's concha cavity. By matching the shape of the area adjacent to the elastic shell 120 and the first outer surface 113 with the shape of the bottom of the wearer's concha cavity, both the wearing comfort of the ear clip headphones at the bottom of the wearer's concha cavity and the stability of the ear clip headphones can be improved.

[0080] Here, the resilient shell 120 may cover a portion of the outer surface 115, or it may cover the entire outer surface 115. For example, as Figure 11 and Figure 15 As shown, the elastic shell 120 can cover the entire outer surface 115; in other words, the area of ​​the support shell 110 not covered by the elastic shell 120 can be the second outer surface 114. The area of ​​the second outer surface 114 can be smaller than the area of ​​the first outer surface 113.

[0081] In some examples, the ear clip-on headphones may include: a second pickup element 620, which may be disposed in the rear cavity 102 by means of bonding, snapping, welding, etc.; the second outer surface 114 located in the peripheral area of ​​the first end 310 of the connector may have a pickup hole 112 that communicates with the rear cavity 102 and is disposed opposite to the position of the second pickup element 620; in the wearing state, the pickup hole 112 may be exposed, and disposing of the pickup hole 112 in the peripheral area of ​​the first end 310 of the connector can reduce the risk of the pickup hole 112 being blocked.

[0082] Here, the structure of the second pickup element 620 is not limited. For example, the second pickup element 620 can be a microphone or other structure capable of picking up sound.

[0083] In some implementations disclosed herein, such as Figure 15 and Figure 16 As shown, the first sound outlet 111 may have a first outer end face 116 on its periphery, and the support shell 110 may include a positioning protrusion 117, which may be disposed on the first outer end face 116; the second mating part 122 may have a positioning groove 128 on its periphery of the second sound outlet 126, and the positioning protrusion 117 may be inserted into the positioning groove 128. By inserting the positioning protrusion 117 into the positioning groove 128, the stability of the connection between the second mating part 122 and the support shell 110 can be improved, and the second mating part 122 can be prevented from moving relative to the support shell 110.

[0084] Of course, in other implementations, the support shell may not have the positioning protrusion 117, and the second mating part 122 may not have the positioning groove 128.

[0085] In this implementation, the positioning protrusion 117 can be block-shaped, strip-shaped, or the like. As an example, the positioning protrusion 117 can be ring-shaped to further improve the stability of the connection between the second mating part 122 and the support shell 110.

[0086] In this implementation, the positioning groove 128 can be block-shaped, strip-shaped, or the like. As an example, the positioning groove 128 can be annular to further improve the stability of the connection between the second mating part 122 and the support shell 110.

[0087] In this implementation, such as Figure 16 As shown, the second mating part 122 may include: a first cylindrical part 124 and a second cylindrical part 125; the first end of the first cylindrical part 124 may have a positioning groove 128, and the first end of the first cylindrical part 124 and the first outer end face 116 may be disposed opposite to each other; the cavity of the first cylindrical part 124 forms a second sound outlet 126; the second end of the first cylindrical part 124 forms a first outer end 127 of the second sound outlet 126; the first end of the second cylindrical part 125 is connected to the outside of the first cylindrical part 124, and the second end of the second cylindrical part 125 is wrapped around the wall of the support shell 110 located on the periphery of the first sound outlet 111.

[0088] Here, a second deformation space can be formed between the second cylindrical portion 125 and the outer surface of the support shell 110. Alternatively, a second deformation space can be formed between the second cylindrical portion 125 and the outer surface of the first cylindrical portion 124. Alternatively, a second deformation space can be formed between the second cylindrical portion 125 and the outer surface of the support shell 110, and a second deformation space can be formed between the second cylindrical portion 125 and the outer surface of the first cylindrical portion 124.

[0089] Here, the first cylindrical portion 124 and the second cylindrical portion 125 can be different parts of a structural component, or they can be connected by means of bonding, snap-fitting, welding, etc. By forming a second deformation space between the outer surfaces of the second cylindrical portion 125 and the first cylindrical portion 124, the deformation space and deformation capability of the second mating portion 122 in the first extension direction Q of the second sound outlet 126 can be further improved.

[0090] In one embodiment, the clip-on earphone may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410; the first housing 100 may include: a support housing 110 and an elastic housing 120. One end of the support housing 110 in a first direction includes a first sound outlet 111; the elastic housing 120 may have a second sound outlet 126; the elastic housing 120 at least covers the opposite ends of the support housing 110 in the first direction, and the second sound outlet 126 of the elastic housing 120 is located outside the first sound outlet 111 and communicates with the first sound outlet 111. The sound-generating component 410 can be disposed within the support shell 110; the sound-generating component 410 divides the space within the support shell 110 into a front cavity 101 and a rear cavity 102, and the first sound outlet 111 communicates with the front cavity 101; the side of the sound-generating component 410 with the 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 first end 310 of the connector is connected to the support shell 110, and the second end 320 of the connector is connected to the second shell 200; wherein, the elastic shell 120 includes a first mating part 121 and a second mating part 122 disposed opposite to each other in the first direction, the second mating part 122 has a second sound outlet 126, and the first mating part 121 and the support shell 110 may have a first deformation space 131.

[0091] The inventors discovered that clip-on earphones can easily cause ear pain during wear. For example, clip-on earphones can easily cause ear pain. In this disclosure, the elastic shell 120 includes a first mating portion 121 and a second mating portion 122 disposed opposite to each other in a first direction. The second mating portion 122 has a second sound outlet 126, and a first deformation space 131 exists between the first mating portion 121 and the support shell 110. The elastic first mating portion 121 and the elastic second mating portion 122 can improve wearing comfort and reduce the risk of ear pain caused by clip-on earphones. At the same time, the elastic second mating portion 122 can improve wearing comfort on the ear canal side, and the elastic first mating portion 121 can improve the comfort of the clip-on earphones clamping the wearer's ear. In addition, the first mating portion 121 can deform through the first deformation space 131. The deformation of the first mating portion 121 can improve the fit and contact area of ​​the first mating portion 121 clamping the ear, thereby further improving wearing comfort and stability; and thus improving the adaptability of the clip-on earphones.

[0092] In this embodiment, the elastic shell 120 may only cover the opposite ends of the support shell 110 in the first direction. Alternatively, the elastic shell 120 may cover the portion between the opposite ends of the support shell 110 in the first direction to increase the area covered by the elastic shell 120. This disclosure does not limit this to this specific embodiment.

[0093] In some examples, a second deformation space 132 may be provided between the second mating part 122 and the support shell 110. The second deformation space 132 may be located at least around the first sound outlet 111 and is arranged in a ring shape. The second mating part 122 can deform around the first sound outlet 111 through the second deformation space 132, thereby increasing the contact area and fit between the second mating part 122 and the wearer's ear canal. Of course, in other examples, the second deformation space 132 may also be located on one side or at least both sides of the first sound outlet 111.

[0094] The second deformation space 132 may be located only around the first sound outlet 111. Of course, the second deformation space 132 may also be located in other areas besides the first sound outlet 111, thereby improving the deformation capability of the second mating part 122 in other areas.

[0095] Some implementations of the embodiments disclosed herein, such as Figure 12 , Figure 13 and Figure 14As shown, one end of the second housing 200 in the height direction can be connected to the second end 320 of the connector, and the second housing 200 in the width direction can be disposed opposite to the first mating part 121. The first mating part 121 in the height direction can include a first mating end 1211 away from the second end 320 of the connector and a second mating end 1212 close to the second end 320 of the connector. The first mating end 1211 and the second housing 200 can have a first clamping gap 521 in the width direction, and the second mating end 1212 and the second housing 200 can have a second clamping gap 522 in the width direction. The first clamping gap 521 is formed by the elastic first mating end 1211, and the second clamping gap 522 is formed by the elastic second mating end 1212. This can further improve the contact area and fit of the ear clip-on headphones, thereby improving wearing comfort and stability.

[0096] In this implementation, the first clamping gap 521 and the second clamping gap 522 can be the same or different. For example, the difference between the first clamping gap 521 and the second clamping gap 522 can be less than or equal to 2 mm. Alternatively, the second clamping gap 522 can be the same as the first clamping gap 521. Another example is that the difference between the first clamping gap 521 and the second clamping gap 522 can be less than or equal to 1.5 mm. Yet another example is that the difference between the first clamping gap 521 and the second clamping gap 522 can be less than or equal to 1 mm. Still another example is that the difference between the first clamping gap 521 and the second clamping gap 522 can be less than or equal to 0.5 mm. By making the first clamping gap 521 and the second clamping gap 522 closer together, the ability of the first mating part 121 to adapt to the ear and the contact area can be further increased, improving the wearing comfort and stability of the ear clip-on headphones.

[0097] In this implementation, the support shell 110 may include a protruding end 118 near the second shell 200 in the width direction, such as... Figure 9 As shown. The first mating end 1211 and the protruding end 118 can contact each other in the width direction, as shown. Figure 12 , Figure 13 and Figure 14 As shown. Here, there may be no deformation space between the first mating end 1211 and the protruding end 118. By supporting the first mating end 1211 with the protruding end 118, the amount of movement of the first mating end 1211 away from the second housing 200 can be reduced, thereby increasing the clamping force of the first mating end 1211 on the ear.

[0098] In this implementation, the second mating end 1212 and the support shell 110 can be spaced apart in the width direction; here, the second mating end 1212 can move relatively a large amount away from the second shell 200, thereby improving the ability of the second mating end 1212 to adapt to the shape of the ear, and improving the contact area and fit of the second mating end 1212 with the ear.

[0099] In some examples, the second mating end 1212 can be the end of the first mating portion 121 closest to the second housing 200; in other words, the second mating end 1212 can be the end of the first mating portion 121 closest to the second housing 200. In still other examples, the second clamping gap 522 between the second mating end 1212 and the second housing 200 can be minimized; in other words, the second mating end 1212 can be the end of the first mating portion 121 closest to the second housing 200.

[0100] By engaging the first mating end 1211 and the second mating end 1212, both the clamping force of the first mating part 121 and the wearing comfort can be improved.

[0101] Some implementations of the embodiments disclosed herein, such as Figure 14 and Figure 16 As shown, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first end 310 of the connector is connected to the second outer surface 114; one end of the outer side surface 115 in the first direction may have a first sound outlet 111, and the other end of the outer side surface 115 in the first direction may have a first region 1151; the elastic shell 120 is wrapped around at least a portion of the first outer surface 113 and the outer side surface 115; a first deformation space 131 may be provided between the first mating part 121 and the first region 1151. By forming the first deformation space 131 between the other end in the first direction and the first region 1151 through the first mating part 121, the deformation capability and adaptability of the elastic shell 120 in the first direction can be further improved.

[0102] In this implementation, such as Figure 9 As shown, one end of the second housing 200 in the height direction can be connected to the second end 320 of the connector, and the second housing 200 in the width direction can be disposed opposite to the outer side 115; in the height direction near the second end 320 of the connector, the distance between the first region 1151 and the second housing 200 in the width direction can gradually increase to adapt to the shape of the wearer's ear and prevent the area of ​​the first region 1151 near the second end 320 of the connector from causing ear pain.

[0103] In this implementation, in the height direction near the second end 320 of the connector, the first region 1151 extends away from the second housing 200 to adapt to the shape of the wearer's ear and prevent the area of ​​the first region 1151 near the second end 320 of the connector from causing ear pain.

[0104] Some implementations of the embodiments disclosed herein, such as Figure 14 and Figure 16 As shown, the second housing 200 is connected to the second end 320 of the connector at one end in the height direction, and the second housing 200 is disposed opposite to the first mating part 121 in the width direction; the first deformation space 131 may have a first width H1 on the side near the second end 320 of the connector, and a second width on the side away from the second end 320 of the connector; the first width H1 may be greater than the second width; in other words, the deformation capacity of the first mating part 121 on the side near the second end 320 of the connector is greater than that on the side away from the second end 320 of the connector, thereby the clamping force can be improved by the part of the first mating part 121 away from the second end 320 of the connector, and the ability to adapt to different ears and the contact area can be improved by the part of the first mating part 121 near the second end 320 of the connector.

[0105] In this implementation, the value of the second width is not limited. The value of the second width can be set relatively small. The value of the second width can be greater than or equal to 0. When the second width is equal to 0, the portion of the first mating part 121 away from the second end 320 of the connector contacts the support shell 110. As an example, the value of the second width can be less than 1 mm, 0.5 mm, 0.3 mm, 0.1 mm, etc.

[0106] In this implementation, the value of the first width H1 is not limited. The value of the first width H1 can be set relatively large. For example, the value of the second width can be 2mm to 3mm, 2.5mm to 3mm, 2mm to 2.5mm, etc.

[0107] In this implementation, the width of the first deformation space 131 can gradually increase in the height direction near the second end 320 of the connector. Alternatively, the width of the first deformation space 131 can first increase and then decrease.

[0108] In some implementations of the embodiments of this disclosure, the elastic shell 120 may include a third mating part 123 that is connected to the first mating part 121 and the second mating part 122 respectively. The third mating part 123 can contact the outer surface of the support shell 110. By having the third mating part 123 contact the support shell 110, the support of the support shell 110 on the elastic shell 120 can be improved.

[0109] In this implementation, a second deformation space 132 is provided between the second mating part 122 and the support shell 110. The second deformation space 132 and the first deformation space 131 can be provided alternately. By providing the second deformation space 132 and the first deformation space 131, the overall deformation area and deformation capability of the ear clip headphones can be improved. Of course, in some other examples, the second mating part 122 can also contact the support shell 110 to improve the overall support and stability of the ear clip headphones.

[0110] In this implementation, one end of the second housing 200 in the height direction can be connected to the second end 320 of the connector, and the second housing 200 in the width direction can be disposed opposite to the first mating part 121; the support housing 110 in the width direction may include a protruding end 118 near the second housing 200; the portion of the support housing 110 in the height direction away from the protruding end 118 can contact the third mating part 123; in other words, the protruding end 118 can be located in the connection area of ​​the first mating part 121 and the third mating part 123, and by having the area near the protruding end 118 contact the first mating part 121 and the third mating part 123 respectively, the overall shape stability of the elastic housing 120 can be improved, thereby improving the wearing stability.

[0111] In some implementations of the embodiments of this disclosure, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first end 310 of the connector is connected to the second outer surface 114; the elastic shell 120 is wrapped around at least a portion of the first outer surface 113 and the outer side surface 115; one end of the outer side surface 115 in the first direction may have a first sound outlet 111, and the other end of the outer side surface 115 in the first direction may have a first deformation space 131; thereby improving the deformation capability and adaptability of the elastic shell 120 in the first direction through the first deformation space 131.

[0112] In this implementation, the shape of the area adjacent to the first outer surface 113 of the elastic shell 120 can match the shape of the bottom of the concha cavity. Here, the shape of the area adjacent to the first outer surface 113 of the elastic shell 120 and the bottom of the concha cavity can be the same or substantially the same to improve the fit between the elastic shell 120 and the bottom of the concha cavity, thereby reducing the risk of the elastic shell 120 shaking and improving the wearing stability.

[0113] In this implementation, such as Figure 14 and Figure 16As shown, in the second direction, the first deformation space 131 can be located on the side close to the first end 310 of the connector to cooperate with the wearer's concha cavity, and the first sound outlet 111 can be located on the side away from the first end 310 of the connector to cooperate with the wearer's ear canal side. By having the first deformation space 131 located on the side close to the first end 310 of the connector and the first sound outlet 111 located on the side away from the first end 310 of the connector, the fit and stability of the clip-on headphones with the ear can be further improved.

[0114] In this implementation, such as Figure 14 and Figure 16 As shown, in the second direction, the distance between the first deformation space 131 and the first end 310 of the connector can be less than the distance between the first sound hole 111 and the first end 310 of the connector. By having the first deformation space 131 located on the side closer to the first end 310 of the connector and the first sound hole 111 located on the side farther from the first end 310 of the connector, the fit and stability of the clip-on headphones with the ear can be further improved.

[0115] In this implementation, the second mating part 122 can extend away from the first mating part 121 in the first direction, and the second mating part 122 can extend away from the first end 310 of the connector in the second direction. The second mating part 122 is used to mate with the wearer's ear canal. By extending away from the first mating part 121 in the first direction and away from the first end 310 of the connector in the second direction, the fit between the second mating part 122 and the ear canal can be improved, thereby improving the overall fit of the clip-on earphone to the ear.

[0116] In some examples, such as Figure 14 and Figure 16 As shown, the first mating part 121 can have a maximum protrusion area 1213 in the first direction. The gap between the maximum protrusion area 1213 and the support shell 110 is the largest. In other words, the first deformation space 131 at the maximum protrusion area 1213 is the largest, and the deformation capacity is the largest. The maximum protrusion area 1213 and the first half shell 103 can be arranged opposite to each other in the first direction. In other words, the maximum protrusion area 1213 is located on the side of the first half shell 103, closer to the first end 310 side of the connector. By making the maximum protrusion area 1213 closer to the first end 310 side of the connector, the maximum protrusion area can be better adapted to the ear, improve the clamping area and clamping stability, and reduce the risk of clamping pain.

[0117] In embodiment two, the clip-on earphone may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410; the first housing 100 may include: a support housing 110 and an elastic housing 120. One end of the support housing 110 in a first direction may include a first sound outlet 111; the elastic housing 120 may have a second sound outlet 126; the elastic housing 120 at least covers the opposite ends of the support housing 110 in the first direction, and the second sound outlet 126 of the elastic housing 120 is located outside the first sound outlet 111 and communicates with the first sound outlet 111; the sound-generating assembly 410 is disposed inside the support housing 110; the sound-generating assembly 410 divides the space inside the support housing 110 into a front cavity 101 and a rear cavity 102, and the first sound outlet 111 communicates with the front cavity 101; the side of the sound-generating assembly 410 with the diaphragm 411 is located on the front cavity 101 side, and it generates sound. The side of component 410 facing away from diaphragm 411 is located on the rear cavity 102 side; the first end 310 of the connector is connected to the support shell 110, and the second end 320 of the connector is connected to the second shell 200; wherein, the elastic shell 120 may include a first mating part 121 and a second mating part 122 disposed opposite to each other in the first direction, the second mating part 122 is used to mate with the wearer's ear canal, the second mating part 122 has a second sound outlet 126, and a second deformation space 132 may be provided between the second mating part 122 and the support shell 110, the second mating part 122 can be deformed through the second deformation space 132 to adjust the size of the second mating part 122.

[0118] The inventors discovered that clip-on headphones can easily cause ear pain during wear. For example, clip-on headphones can easily cause ear pain in the ear canal. In this disclosure, a second mating part 122 is used to mate with the wearer's ear canal. The second mating part 122 has a second sound outlet 126, and a second deformation space 132 is provided between the second mating part 122 and the support shell 110. The second mating part 122 can deform through the second deformation space 132 to adjust its size. The elasticity of the second mating part 122 improves the fit between the second mating part 122 and the ear canal, reduces the risk of the second mating part 122 causing ear pain, and thus improves wearing comfort and adaptability.

[0119] In the disclosed embodiments, the area where the second deformable space 132 is disposed is not limited. For example, the second deformable space 132 may be disposed at least around the outer side of the first sound outlet 111. As an example, the angle of the second deformable space 132 around the outer side of the first sound outlet 111 may be greater than or equal to 90 degrees. As another example, the angle of the second deformable space 132 around the outer side of the first sound outlet 111 may be greater than or equal to 180 degrees. As yet another example, the angle of the second deformable space 132 around the outer side of the first sound outlet 111 may be greater than or equal to 270 degrees. As yet another example, the angle of the second deformable space 132 around the outer side of the first sound outlet 111 may be equal to 360 degrees. As yet another example, the angle of the second deformable space 132 around the outer side of the first sound outlet 111 may be between 90 degrees and 360 degrees. By setting the angle of the second deformable space 132 around the outer side of the first sound outlet 111 to be relatively large and appropriate, the fit of the second mating part 122 around the periphery of the first sound outlet 111 and the ear canal can be improved.

[0120] For example, the second deformable space 132 may be located on at least two sides of the first sound outlet 111. Alternatively, the second deformable space 132 may be located on at least three sides of the first sound outlet 111. Yet another example is that the second deformable space 132 may be located around the first sound outlet 111 and arranged in a ring shape. By setting the angle of the second deformable space 132 around the outer side of the first sound outlet 111 to be relatively large and suitable, the fit of the second mating part 122 between the second mating part 122 and the ear canal around the first sound outlet 111 can be improved.

[0121] The second deformation space 132 can be disposed on the periphery of the first sound outlet 111, or it can be disposed on the periphery of other areas of the support shell 110. This disclosure does not limit it in this way.

[0122] In some examples, such as Figure 14 and Figure 16 As shown, the second deformable space 132 may include a first space 1324 and a second space 1325 that are adjacent and connected. The first space 1324 is arranged in a ring around the first sound outlet 111, and the second space 1325 may be located on the periphery of the area outside the first sound outlet 111 on the support shell. The second mating part 122 can deform through the first space 1324 to adjust the size of the mating area between the second mating part 122 and the wearer's ear canal. The second mating part 122 can deform through the second space 1325 to adjust the size of the mating area between the second mating part 122 and the wearer's concha cavity. Thus, by setting a relatively large second deformable space 132, the fit between the second mating part 122 and the ear canal can be improved, and the fit between the second mating part 122 and the concha cavity can also be improved, thereby improving the overall adaptability and fit of the clip-on headphones.

[0123] Here, the second space 1325 can be annular. The length of the second space 1325 in the first direction can be greater than the length of the first space 1324 in the first direction.

[0124] Here, the length of the second space 1325 in the first extension direction Q of the second sound outlet 126 can be greater than the length of the first space 1324 in the first extension direction Q of the second sound outlet 126.

[0125] In some other examples, such as Figure 14 and Figure 16 As shown, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first end 310 of the connector is connected to the second outer surface 114; the shape of the region of the elastic shell 120 adjacent to the first outer surface 113 matches the bottom shape of the concha cavity; one end of the outer side surface 115 in the first direction may have a first sound outlet 111; the second deformation space may include a first subspace 1326 located on the side of the first outer surface 113 and a second subspace 1327 located on the side of the second outer surface 114; in the first direction, the length of the first subspace 1326 may be greater than the length of the second subspace 1327. By making the first subspace 1326 on the side of the first outer surface 113 relatively long, the area of ​​the deformable region of the elastic shell 120 and the concha cavity can be increased; by making the second subspace 1327 on the side of the second outer surface 114 relatively short, the fit at the ear canal can be improved and the volume of the elastic shell 120 can be reduced, thus achieving a balance between the fit and miniaturization of the ear clip-on headphones.

[0126] In some other examples, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first end 310 of the connector is connected to the second outer surface 114; the shape of the area of ​​the elastic shell 120 adjacent to the first outer surface 113 matches the bottom shape of the concha cavity; one end of the outer side surface 115 in the first direction has a first sound outlet 111; the second deformation space 132 is annularly disposed at least around the periphery of the first sound outlet 111; wherein, the length of the second deformation space 132 in the first direction can gradually decrease from the first outer surface 113 to the second outer surface 114, which can make the setting area of ​​the second deformation space 132 smoother and increase the area of ​​the deformable area of ​​the elastic shell 120 and the concha cavity.

[0127] In the disclosed embodiment, since the second mating part 122 has a second sound outlet 126, the second sound outlet 126 of the elastic shell 120 is located outside the first sound outlet 111 and communicates with the first sound outlet 111; the second mating part 122 can also increase the length of the first shell 100 in the first direction, so that the audio of the sound-generating component 410 is closer to the wearer's ear canal through the second sound outlet 126, thereby improving the audio effect of the clip-on headphones.

[0128] The length of the second mating part 122 increasing in the first direction is not limited. For example, the distance between the first outer end face 116 on the periphery of the first sound outlet 111 and the first outer end face 127 on the periphery of the second sound outlet 126 can be greater than or equal to 0.5 mm, 1 mm, 1.5 mm, etc. As another example, the distance between the first outer end face 116 on the periphery of the first sound outlet 111 and the first outer end face 127 on the periphery of the second sound outlet 126 can be 0.5 mm to 3 mm, 0.5 mm to 2 mm, 1 mm to 2 mm, etc. Here, the elastic shell 120 can be a second elastic shell 1202, such as... Figure 12 As shown, the spacing can be a second spacing L2. The elastic shell 120 can be a third elastic shell 1203, as shown. Figure 13 As shown, the spacing can be the third spacing L3. The elastic shell 120 can be the fourth elastic shell 1204, as shown. Figure 14 and Figure 16 As shown, the spacing can be the fourth spacing L4.

[0129] In some implementations of the embodiments of this disclosure, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; the first end 310 of the connector is connected to the second outer surface 114; the shape of the region of the elastic shell 120 adjacent to the first outer surface 113 matches the bottom shape of the concha cavity; one end of the outer side surface 115 in the first direction may have a first sound outlet 111, and the other end of the outer side surface 115 in the first direction may have a first region 1151; the elastic shell 120 covers at least a portion of the first outer surface 113 and the outer side surface 115.

[0130] In this implementation, the first mating part 121 and the first region 1151 can contact each other, such as Figure 11 and Figure 15 As shown. Of course, there can also be a first deformation space 131 between the first mating part 121 and the first region 1151, such as... Figure 12 , Figure 13 and Figure 14 As shown, the first deformation space 131 can further improve the adaptability of the first mating part 121 to the ear.

[0131] In this implementation, one end of the second housing 200 in the height direction can be connected to the second end 320 of the connector, and the second housing 200 in the width direction can be disposed opposite to the outer side 115; in the height direction near the second end 320 of the connector, the width of the first deformation space 131 can gradually increase, or the width of the first deformation space 131 can first increase and then decrease, so as to improve the fit and wearing stability of the first mating part 121 with the ear.

[0132] In some implementations of this disclosure, one end of the second housing 200 in the height direction is connected to the second end 320 of the connector, and the second housing 200 is disposed opposite to the first mating part 121 in the width direction. The first mating part 121 in the height direction may include a first mating end 1211 away from the second end 320 of the connector and a second mating end 1212 close to the second end 320 of the connector. The first mating end 1211 and the second housing 200 may have a first clamping gap 521 in the width direction, and the second mating end 1212 and the second housing 200 may have a second clamping gap 522 in the width direction. The difference between the first clamping gap 521 and the second clamping gap 522 may be less than or equal to 2 mm, so as to further improve the fit and wearing stability of the first mating part 121 with the ear.

[0133] The first clamping gap 521 and the second clamping gap 522 have been described in the above embodiment 1, and will not be repeated here.

[0134] In some implementations of this disclosure, the elastic shell 120 may include a third mating part 123 that is connected to the first mating part 121 and the second mating part respectively. The third mating part 123 can contact the outer surface of the support shell 110. By supporting the third mating part 123 through the support shell 110, the overall shape stability of the elastic shell 120 can be improved.

[0135] In this implementation, a first deformation space 131 may be provided between the first mating part 121 and the support shell 110; the first deformation space 131 and the second deformation space 132 may be provided at intervals, and the stability of the overall shape of the elastic shell 120 can be improved by providing the first deformation space 131 and the second deformation space 132 at intervals.

[0136] In embodiment three, the clip-on earphone may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410; the first housing 100 may include: a support housing 110 and an elastic housing 120. One end of the support housing 110 in a first direction may include a first sound outlet 111; the elastic housing 120 may be detachably disposed outside the support housing 110 and has a second sound outlet 126; the sound-generating assembly 410 may be disposed inside the support housing 110; the sound-generating assembly 410 may divide the space inside the support housing 110 into a front cavity 101 and a rear cavity 102, and the first sound outlet 111 communicates with the front cavity 101; the side of the sound-generating assembly 410 where the diaphragm 411 is disposed is located on the front cavity 101 side, and the sound-generating assembly 410... The side facing away from the diaphragm 411 is located on the rear cavity 102 side; the first end 310 of the connector is connected to the support shell 110, and the second end 320 of the connector is connected to the second shell 200; wherein, when the elastic shell 120 is disposed outside the support shell 110, the elastic shell 120 at least covers the opposite ends of the support shell 110 in the first direction, the second sound outlet 126 of the elastic shell 120 is located outside the first sound outlet 111 and communicates with the first sound outlet 111, and the clip-on earphone forms an in-ear earphone, such as Figures 10 to 14 As shown; when the elastic shell 120 is not located outside the support shell 110, the clip-on headphones form an open-back design, such as... Figure 7 , Figure 8 and Figure 9 As shown.

[0137] The inventors discovered that clip-on headphones have a relatively fixed size, and their position relative to the wearer's ear is fixed when worn, resulting in poor adaptability. In this disclosure, when the elastic shell 120 is positioned outside the support shell 110, the clip-on headphones can function as in-ear headphones; these can be either fully in-ear or semi-in-ear headphones. When the elastic shell 120 is not positioned outside the support shell 110, the clip-on headphones can function as open-back headphones. This allows the clip-on headphones to have different modes to adapt to different wearing needs, improving their adaptability to various requirements.

[0138] In this embodiment, by placing the elastic shell 120 outside the support shell 110, the size of the first shell 100 can be increased, reducing the distance between the sound outlet and the ear canal. This allows more audio to be transmitted directly into the wearer's ear canal, adapting to scenarios requiring in-ear headphones, such as noisy environments. By removing the elastic shell 120, the size of the first shell 100, formed solely by the support shell 110, is relatively small, allowing more external sound to be transmitted into the ear canal, adapting to scenarios requiring open-back headphones, such as sports. The detachable placement of the elastic shell 120 outside the support shell 110 increases the usage modes of the clip-on headphones, enabling a single clip-on headphone to have different modes, thereby greatly improving the adaptability of the clip-on headphones.

[0139] In this embodiment, when the elastic shell 120 is disposed outside the support shell 110, the increased length of the elastic shell 120 on the sound outlet side is not limited. For example, the distance between the first outer end face 116 on the periphery of the first sound outlet 111 and the first outer end face 127 on the periphery of the second sound outlet 126 can be greater than or equal to 0.5 mm, 1 mm, 1.5 mm, etc. As another example, the distance between the first outer end face 116 on the periphery of the first sound outlet 111 and the first outer end face 127 on the periphery of the second sound outlet 126 can be 0.5 mm to 3 mm, 0.5 mm to 2 mm, 1 mm to 2 mm, etc.

[0140] In some examples, the elastic shell 120 can be a first elastic shell 1201, such as Figure 11 and Figure 15 As shown, the spacing can be a first spacing L1. The elastic shell 120 can also be a second elastic shell 1202, as... Figure 12 As shown, the spacing can be a second spacing L2. The elastic shell 120 can also be a third elastic shell 1203, as... Figure 13 As shown, the spacing can be a third spacing L3. The elastic shell 120 can also be a fourth elastic shell 1204, as... Figure 14 and Figure 16 As shown, the spacing can be the fourth spacing L4.

[0141] In some implementations of this embodiment, the elastic shell 120 may include a first mating portion 121 and a second mating portion 122 disposed opposite to each other in the first direction. The second mating portion 122 may have a second sound outlet 126. When the elastic shell 120 is disposed outside the support shell 110, a clamping gap 520 may be formed between the first mating portion 121 and the second shell 200. The second mating portion 122 is used to mate with the wearer's ear canal. The first mating portion 121 can further increase the size of the elastic shell 120 in the first direction, thereby making it easier for the first shell 100 with the elastic shell 120 disposed to approach the wearer's ear side. At the same time, the clamping gap 520 formed by the elastic first mating portion 121 can improve both wearing comfort and the adaptability of the ear clip-on headphones.

[0142] In this implementation, when the elastic shell 120 is disposed outside the support shell 110, the increased dimension of the first mating portion 121 in the first direction is not limited. For example, the length of the first mating portion 121 protruding from the support shell 110 in the first direction can be greater than or equal to 0.5mm, 1mm, 2mm, 2.5mm, etc. As another example, the length of the first mating portion 121 protruding from the support shell 110 in the first direction can be 0.5mm to 2.5mm, 1mm to 2mm, 0.5mm to 3mm, etc.

[0143] In this implementation, the dimension of the elastic shell 120 in the first direction can be larger than the dimension of the support shell 110 in the first direction. The dimension of the elastic shell 120 in a third direction can be larger than the dimension of the support shell 110 in a third direction. The value by which the dimension of the elastic shell 120 exceeds the dimension of the support shell 110 is not limited.

[0144] For example, in the first direction, the difference between the maximum size of the elastic shell 120 and the maximum size of the support shell 110 can be greater than or equal to 1 mm, 2 mm, 3 mm, 4 mm, etc. As another example, in the first direction, the difference between the maximum size of the elastic shell 120 and the maximum size of the support shell 110 can be 1 mm to 4.5 mm, 2 mm to 3.5 mm, 2 mm to 3 mm, etc.

[0145] In this implementation, when the elastic shell 120 is disposed outside the support shell 110, the first mating part 121 and the support shell 110 can have a first deformation space 131 to increase the ability of the first mating part 121 to adapt to and clamp different ears. Of course, the first mating part 121 can also contact the support shell 110 to improve the stability of the shape of the first mating part 121.

[0146] In this implementation, when the elastic shell 120 is disposed outside the support shell 110, the second mating part 122 and the support shell 110 can have a second deformation space to improve the ability of the second mating part 122 to adapt to different ear canals. Of course, the second mating part 122 can also contact the support shell 110 to improve the stability of the shape of the second mating part 122.

[0147] In this implementation, when the elastic shell 120 is disposed outside the support shell 110, the second mating part 122 and the support shell 110 can have a second deformation space 132. The second deformation space 132 can be arranged in a ring around the periphery of the first sound outlet 111. The second mating part 122 can be deformed through the second deformation space 132 to adjust the size of the second mating part 122. By having the second deformation space 132 arranged in a ring around the periphery of the first sound outlet 111, the adaptability of the periphery of the first sound outlet 111 to the ear canal can be improved, thereby improving the fit of the periphery of the first sound outlet 111 to the ear canal.

[0148] In this implementation, the second deformable space 132 may include an adjacent and connected first space 1324 and second space 1325; the first space 1324 may be arranged in a ring around the periphery of the first sound outlet 111, and the second space 1325 may be located on the periphery of the area outside the first sound outlet 111 on the support shell; the second mating part 122 can deform through the first space 1324 to adjust the size of the mating area between the second mating part 122 and the wearer's ear canal; the second mating part 122 can deform through the second space 1325 to adjust the size of the mating area between the second mating part 122 and the wearer's concha cavity. The first space 1324 and the second space 1325 have been described in the above embodiments and will not be repeated here.

[0149] In this implementation, the first sound outlet 111 may have a first outer end face 116 on its periphery, and the support shell 110 may include a positioning protrusion 117. The positioning protrusion 117 may be disposed on the first outer end face 116; the second mating part 122 may have a positioning groove 128 on its periphery of the second sound outlet 126, and the positioning protrusion 117 may be inserted into the positioning groove 128 to improve the positional stability of the second mating part 122. The positioning protrusion 117, the positioning groove 128, and the second mating part 122 have been described in the above embodiments, and will not be repeated here.

[0150] In some implementations of the embodiments of this disclosure, the elastic shell 120 is disposed outside the support shell 110. In the wearing state, the first outer end portion 127 of the second sound outlet 126 of the elastic shell 120 has a first gap with the middle of the wearer's ear canal; if the elastic shell 120 is not disposed outside the support shell 110, in the wearing state, the first outer end face 116 of the first sound outlet 111 has a second gap M0 with the middle of the wearer's ear canal, such as... Figure 21 As shown; the first gap can be smaller than the second gap M0; in other words, the first outer end 127 is closer to the middle of the wearer's ear canal than the first outer end face 116, so that the audio of the sound-generating component 410 can be relatively more introduced into the ear canal through the first outer end 127.

[0151] The middle part of the wearer's ear canal can be the isthmus, usually located at the junction of the cartilaginous and bony parts. Here, the diameter of the middle part of the ear canal can be the smallest. Of course, the middle part of the ear canal can also be located 1 to 2 cm inward from the entrance of the ear canal.

[0152] In this implementation, the elastic shell 120 can be a first elastic shell 1201, such as... Figure 3 and Figure 11 As shown, the first gap can be a first distance M1, such as... Figure 23 As shown. The elastic shell 120 can be a second elastic shell 1202, such as... Figure 4 and Figure 12 As shown, the first gap can be the second distance M2, such as... Figure 24 As shown. The elastic shell 120 can be a third elastic shell 1203, such as... Figure 5 and Figure 13 As shown, the first gap can be the third distance M3, such as... Figure 25 As shown. The elastic shell 120 can be a fourth elastic shell 1204, such as... Figure 6 and Figure 14 As shown, the first gap can be the fourth distance M4, such as... Figure 26 As shown.

[0153] In some implementations of the embodiments of this disclosure, such as Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, the elastic shell 120 is disposed outside the support shell 110. In the wearing state, the first outer end 127 of the elastic shell 120 located at the second sound outlet 126 can be located inside the wearer's ear canal, so that the audio of the sound-generating component 410 can be directly transmitted to the ear canal through the elastic shell 120. Figure 21 As shown, the elastic shell 120 is not located outside the support shell 110. When worn, the first outer end face 116 of the first sound outlet 111 can be located outside the wearer's ear canal so that external sounds can also enter the ear canal.

[0154] In embodiment four, the clip-on earphone may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410; the first housing 100 may include: a support housing 110 and at least two elastic housings 120. One end of the support shell 110 in the first direction may include a first sound outlet 111; at least two elastic shells 120 may have second sound outlets 126; the elastic shells 120 are detachably wrapped around at least the opposite ends of the support shell 110 in the first direction, and the second sound outlets 126 of the elastic shells 120 are located outside the first sound outlets 111 and communicate with the first sound outlets 111; the sound generating assembly 410 is disposed inside the support shell 110; the sound generating assembly 410 divides the space inside the support shell 110 into a front cavity 101 and a rear cavity 102, and the first sound outlet 111 communicates with the front cavity 101; the side of the sound generating assembly 410 with the diaphragm 411 is located on the front cavity 101 side, and the side of the sound generating assembly 410 facing away from the diaphragm 411 is located on the rear cavity 102 side; the first end 310 of the connector is connected to the support shell 110, and the second end 320 of the connector is connected to the second shell 200; wherein, the maximum dimensions of at least two elastic shells 120 in the first direction are different.

[0155] The inventors discovered that clip-on headphones have a relatively fixed size, and their position relative to the wearer's ear is relatively fixed when worn, resulting in poor adaptability. In this disclosure, because at least two elastic shells 120 have different maximum dimensions in the first direction, the distance between the second sound outlet 126 and the wearer's ear canal can be varied by using elastic shells 120 of different sizes. This allows for adjustment of the distance between the sound outlet and the wearer's ear canal to accommodate different wearing needs, improving the clip-on headphones' adaptability to various requirements. For example, for the same wearer, different modes of headphones, such as open-back or in-ear, can be created using at least two elastic shells 120 of different sizes. Furthermore, for wearers with different ear sizes, a suitable elastic shell 120 can be selected from at least two elastic shells 120 of different sizes, thereby improving the clip-on headphones' adaptability to different ear sizes.

[0156] In this embodiment of the disclosure, the number of at least two elastic shells 120 is not limited. For example, the number of at least two elastic shells 120 can be two, three, four, five, etc.

[0157] In some implementations of the embodiments of this disclosure, at least two elastic shells 120 may include a first elastic shell 1201 and a second elastic shell 1202. The maximum dimension of the second elastic shell 1202 in the first direction may be greater than the maximum dimension of the first elastic shell 1201 in the first direction. The first elastic shell 1201 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the first elastic shell 1201 may have a first distance M1 between it and the middle of the wearer's ear canal. Figure 22 and Figure 23 As shown; the second elastic shell 1202 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the second elastic shell 1202 can have a second distance M2 between it and the middle of the wearer's ear canal, such as... Figure 24 As shown; the first distance M1 can be greater than the second distance M2. By using a first elastic shell 1201 with a relatively small size in the first direction, the second sound outlet 126 can be relatively far from the middle of the wearer's ear canal to accommodate the need for a relatively small size first shell 100. By using a second elastic shell 1202 with a relatively large size in the first direction, the second sound outlet 126 can be relatively close to the middle of the wearer's ear canal to accommodate the need for a relatively large size first shell 100.

[0158] In this implementation, the maximum dimension of the first elastic shell 1201 in the first direction is not limited. For example, the first elastic shell 1201 may have a first maximum dimension in the first direction, which may be 12mm to 15mm, 13mm to 14mm, 12mm to 15mm, etc.

[0159] In this implementation, the maximum dimension of the second elastic shell 1202 in the first direction is not limited. For example, the second elastic shell 1202 may have a second maximum dimension in the first direction, which may be 15mm to 19mm, 16mm to 18mm, 17mm to 18mm, etc.

[0160] In this implementation, at least two elastic shells 120 may further include a third elastic shell 1203 and a fourth elastic shell 1204. The maximum dimension of the third elastic shell 1203 in the first direction may be greater than the maximum dimension of the second elastic shell 1202 in the first direction; the maximum dimension of the fourth elastic shell 1204 in the first direction may be greater than the maximum dimension of the third elastic shell 1203 in the first direction. The third elastic shell 1203 is wrapped around the support shell 110. When worn, the second sound outlet 126 of the third elastic shell 1203 can have a third distance M3 between it and the middle of the wearer's ear canal. Figure 25As shown; the second distance M2 can be greater than the third distance M3; the fourth elastic shell 1204 is wrapped outside the support shell 110, and in the wearing state, the second sound outlet 126 of the fourth elastic shell 1204 and the middle of the wearer's ear canal can have a fourth distance M4, such as Figure 26 As shown; the third distance M3 can be greater than the fourth distance M4. By setting four elastic shells 120 of different sizes, the adaptability of the clip-on headphones can be further improved.

[0161] In the first direction, the maximum dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can increase sequentially. When worn, the distances between the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 and the middle of the wearer's ear canal can decrease sequentially. The wearer can more easily choose a relatively suitable elastic shell 120 according to their needs and ear size.

[0162] In this implementation, the maximum dimension of the third elastic shell 1203 in the first direction is not limited. For example, the third elastic shell 1203 may have a third maximum dimension in the first direction, which may be 19mm to 24mm, 21mm to 22mm, 20mm to 23mm, etc.

[0163] In this implementation, the maximum dimension of the fourth elastic shell 1204 in the first direction is not limited. For example, the fourth elastic shell 1204 may have a fourth maximum dimension in the first direction, which may be 24mm to 28mm, 25mm to 27mm, 26mm to 27mm, etc.

[0164] In this implementation, the headphone mode that the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203 and the fourth elastic shell 1204 can form is not limited.

[0165] For example, the first elastic shell 1201 can be used to form an open-back headphone, such as... Figure 22 As shown, at least one of the second elastic shell 1202, the third elastic shell 1203 and the fourth elastic shell 1204 can be used to form a semi-in-ear headphone or a fully in-ear headphone.

[0166] For example, the first elastic shell 1201 can be used to form an open-back headphone, the second elastic shell 1202 and / or the third elastic shell 1203 can be used to form a semi-in-ear headphone, and the fourth elastic shell 1204 can be used to form a fully in-ear headphone. Here, the second elastic shell 1202 can form a semi-in-ear headphone, and the third elastic shell 1203 can form a fully in-ear headphone or a semi-in-ear headphone. Alternatively, the third elastic shell 1203 can form a semi-in-ear headphone, and the second elastic shell 1202 can form a semi-in-ear headphone or an open-back headphone.

[0167] For example, the first elastic shell 1201 and / or the second elastic shell 1202 can be used to form a semi-in-ear headphone, and the third elastic shell 1203 and / or the fourth elastic shell 1204 can be used to form a fully in-ear headphone. Here, the first elastic shell 1201 can be used to form a semi-in-ear headphone, and the second elastic shell 1202 can form either a semi-in-ear headphone or a fully in-ear headphone. Alternatively, the second elastic shell 1202 can be used to form a semi-in-ear headphone, and the first elastic shell 1201 can form either a semi-in-ear headphone or an open-back headphone. The fourth elastic shell 1204 can be used to form a fully in-ear headphone, and the third elastic shell 1203 can be used to form either a fully in-ear headphone or a semi-in-ear headphone.

[0168] It should be noted that, for different ear sizes, the same elastic shell 120 in the first elastic shell 1201, second elastic shell 1202, third elastic shell 1203, and fourth elastic shell 1204 can form different headphone modes. For example, the first elastic shell 1201 can form a fully in-ear headphone or a semi-in-ear headphone for wearers with smaller ear sizes, while the first elastic shell 1201 can form an open-back headphone or a semi-in-ear headphone for wearers with larger ear sizes.

[0169] In this implementation, the arrangement of increasing dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 in the first direction is not limited. The first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can have different dimensions by setting different thicknesses or different gaps with the support shell 110.

[0170] For example, the elastic shell 120 may include a first mating portion 121 and a second mating portion 122 disposed opposite to each other in the first direction, and the second mating portion 122 may have a second sound outlet 126; the gap between the first mating portion 121 of the second elastic shell 1202 and the supporting shell 110 may be greater than the gap between the first mating portion 121 of the first elastic shell 1201 and the supporting shell 110; the gap between the second mating portion 122 of the second elastic shell 1202 and the supporting shell 110 may be greater than the gap between the second mating portion 122 of the first elastic shell 1201 and the supporting shell 110. By setting the gaps between the first mating portion 121 and the second mating portion 122 of the second elastic shell 1202 and the supporting shell 110 to be relatively large, the deformation capacity and adaptability of the second elastic shell 1202 can be improved.

[0171] In some examples, such as Figure 4 As shown, the first mating part 121 of the second elastic shell 1202 and the support shell 110 may have a first deformation space 131; the second mating part 122 of the second elastic shell 1202 and the support shell 110 may have a first sub-second deformation space 1321; the size of the second elastic shell 1202 in the first direction can be increased through the first deformation space 131 and the first sub-second deformation space 1321.

[0172] In some examples, such as Figure 1 , Figure 2 and Figure 3 As shown, the first mating part 121 of the first elastic shell 1201 can contact the support shell 110; the second mating part 122 of the first elastic shell 1201 can contact the support shell 110. Here, the support shell 110 directly contacts and supports the first mating part 121 and the second mating part 122 of the first elastic shell 1201, thereby improving the shape stability of the first elastic shell 1201.

[0173] In some examples, such as Figure 4 , Figure 5 and Figure 6As shown, the dimensions of the first mating portion 121 of the third elastic shell 1203, the first mating portion 121 of the fourth elastic shell 1204, and the first mating portion 121 of the second elastic shell 1202 can be the same. For example, the first mating portion 121 of the third elastic shell 1203 and the first mating portion 121 of the fourth elastic shell 1204 can also have a first deformation space 131 between them and the support shell 110. The second mating portion 122 of the third elastic shell 1203 can have a second sub-second deformation space 1322 between it and the support shell 110; the second mating portion 122 of the fourth elastic shell 1204 can have a third sub-second deformation space 1323 between it and the support shell 110; the third sub-second deformation space 1323 can be larger than the second sub-second deformation space 1322, and the second sub-second deformation space 1322 can be larger than the first sub-second deformation space 1321. By setting the second deformation space 132 differently, the third elastic shell 1203, the fourth elastic shell 1204 and the second elastic shell 1202 can have different dimensions in the first direction; it is also possible to make the third elastic shell 1203, the fourth elastic shell 1204 and the second elastic shell 1202 have different deformation capabilities.

[0174] Here, the first deformable space 131, the first sub-second deformable space 1321, the second sub-second deformable space 1322, and the third sub-second deformable space 1323 can be used to communicate with the outside through the gap between the support shell 110 and the elastic shell 120. In other words, when the first mating part 121 and the second mating part 122 are deformed, the gas in the first deformable space 131, the first sub-second deformable space 1321, the second sub-second deformable space 1322, and the third sub-second deformable space 1323 can be discharged into the outside through the gap between the support shell 110 and the elastic shell 120, and the gas in the outside can enter the first deformable space 131, the first sub-second deformable space 1321, the second sub-second deformable space 1322, and the third sub-second deformable space 1323 through the gap between the support shell 110 and the elastic shell 120.

[0175] In this implementation, such as Figure 7 and Figure 9As shown, the support shell 110 may include a first outer surface 113 and a second outer surface 114 disposed opposite to each other in the second direction, and an outer side surface 115 connected to the first outer surface 113 and the second outer surface 114 respectively; one end of the outer side surface 115 in the first direction may have a first sound outlet 111; the second direction may be perpendicular to the first direction; a second deformation space 132 may be provided between the second mating part 122 and the support shell 110, the second deformation space 132 including a first space 1324 and a second space 1325 that are adjacent and connected; the first space 1324 may be located around the first sound outlet 111, and the second space 1325 may be located around the area of ​​the support shell outside the area where the first sound outlet 111 is located. The first space 1324 and the second space 1325 have been described in the above embodiments, and will not be repeated here.

[0176] Here, the first space 1324 of the third sub-second deformation space 1323 can be greater than the first space 1324 of the second sub-second deformation space 1322, and the first space 1324 of the second sub-second deformation space 1322 can be greater than the first space 1324 of the first sub-second deformation space 1321.

[0177] Here, the second space 1325 of the third sub-second deformation space 1323 can be greater than the second space 1325 of the second sub-second deformation space 1322, and the second space 1325 of the second sub-second deformation space 1322 can be greater than the second space 1325 of the first sub-second deformation space 1321.

[0178] In this implementation, the dimension of the second elastic shell 1202 in the second direction can be larger than that of the first elastic shell 1201 in the second direction; the dimension of the third elastic shell 1203 in the second direction can be larger than that of the second elastic shell 1202 in the second direction; and the dimension of the fourth elastic shell 1204 in the second direction can be larger than that of the third elastic shell 1203 in the second direction. Here, the dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 in the second direction can be increased sequentially by different second deformation spaces 132. Of course, the dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 in the second direction can also be increased sequentially by setting different thicknesses. This disclosure does not limit this.

[0179] In this implementation, the dimension of the second elastic shell 1202 in the third direction can be larger than the dimension of the first elastic shell 1201 in the third direction; the dimension of the third elastic shell 1203 in the third direction can be larger than the dimension of the second elastic shell 1202 in the third direction; the dimension of the fourth elastic shell 1204 in the third direction can be larger than the dimension of the third elastic shell 1203 in the third direction; the first direction can be perpendicular to the second direction and the third direction, respectively. Here, the dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 in the third direction can be increased sequentially by different second deformation spaces 132. Of course, the dimensions of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 in the third direction can also be increased sequentially by setting different thicknesses. This disclosure does not limit this.

[0180] In some implementations of the embodiments of this disclosure, the ear-clip earphone may further include a first pickup element 610 and a second pickup element 620. The first pickup element 610 may be disposed in the front cavity 101 by means of bonding, snapping, welding, etc.; the first pickup element 610 may be used to pick up the sound in the wearer's ear canal; the second pickup element 620 may be disposed in the rear cavity 102 by means of bonding, snapping, welding, etc.; the second pickup element 620 may be used to pick up the sound of the external environment; at least one of the at least two elastic shells 120 is used to form a semi-in-ear earphone or a fully in-ear earphone. When the semi-in-ear earphone or the fully in-ear earphone is worn, the sound picked up by the first pickup element 610 and the second pickup element 620 is used for noise reduction, so that the noise reduction function of a semi-in-ear earphone or a fully in-ear earphone can also be achieved through the ear-clip earphone.

[0181] In this implementation, the noise cancellation function can be activated via button 440 or via the operating software controlling the earbuds. This disclosure does not limit this.

[0182] In this implementation, the first pickup element 610 and the second pickup element 620 can be structures capable of picking up sound, such as microphones. In some examples, the first pickup element 610 can be a feedback microphone, and the second pickup element 620 can be a feedforward microphone.

[0183] In some examples, when the clip-on headphones function as semi-in-ear or fully in-ear headphones, the wearer can manually switch the noise cancellation function using button 440. The noise cancellation chip of the clip-on headphones controls the first pickup element 610 and the second pickup element 620 to work together to generate reverse sound waves, effectively suppressing wideband noise. This transforms the clip-on headphones into noise-canceling headphones, significantly improving the user's listening clarity in noisy environments such as airplane cabins and subways, and solving the core pain point that clip-on headphones have always struggled to support high-quality noise cancellation.

[0184] In embodiment five, the clip-on earphone may include: a first housing 100, a second housing 200, a connector 300, and a sound-generating assembly 410; the first housing 100 may include: a support housing 110 and at least two elastic housings 120. One end of the support housing 110 in a first direction may include a first sound outlet 111; at least two elastic housings 120 may have second sound outlets 126; the elastic housings 120 are detachably wrapped around at least the opposite ends of the support housing 110 in the first direction, and the second sound outlets 126 of the elastic housings 120 are located outside the first sound outlet 111 and communicate with the first sound outlet 111; the sound-generating assembly 410 is disposed within the support housing 110; the sound-generating assembly 410 divides the space within the support housing 110 into a front cavity 101 and a rear cavity 102, and the first sound outlet 111 communicates with the front cavity 101; one side of the sound-generating assembly 410 with a diaphragm 411 is located on the front cavity 101 side, and the sound-generating assembly... The side of component 410 facing away from diaphragm 411 is located on the rear cavity 102 side; the first end 310 of the connector is connected to the support shell 110, and the second end 320 of the connector is connected to the second shell 200; wherein, when one of the at least two elastic shells 120 is wrapped outside the support shell 110, one of the at least two elastic shells 120 is used to have a first relative positional relationship with the wearer's ear canal; when the other elastic shell 120 is wrapped outside the support shell 110, the elastic shell 120 is used to have a second relative positional relationship with the wearer's ear canal, and the first relative positional relationship and the second relative positional relationship are different.

[0185] The inventors discovered that clip-on headphones have a relatively fixed size and a relatively fixed position relative to the wearer's ear when worn, resulting in poor adaptability. In this disclosure, when one of the at least two elastic shells 120 is wrapped outside the support shell 110, one of the elastic shells 120 has a first relative positional relationship with the wearer's ear canal; when the other elastic shell 120 is wrapped outside the support shell 110, it has a second relative positional relationship with the wearer's ear canal. The first and second relative positional relationships are different, thereby enabling the clip-on headphones to have different positional relationships with the wearer's ear canal to adapt to different wearing needs, improving the clip-on headphones' ability to adapt to various wearing requirements.

[0186] In the embodiments of this disclosure, the relative positional relationship between the elastic shell 120 and the wearer's ear canal may include distance, degree of sealing, etc. This disclosure does not limit this aspect.

[0187] For example, in a first relative positional relationship, one of the at least two elastic shells 120 is relatively far from the middle of the wearer's ear canal; in a second relative positional relationship, the other elastic shell 120 is relatively close to the middle of the wearer's ear canal. As an example, in the first relative positional relationship, the ear-clip earphone can form an open-back earphone; in the second relative positional relationship, the ear-clip earphone can form an in-ear earphone. As yet another example, in the first relative positional relationship, the ear-clip earphone can form a semi-in-ear earphone; in the second relative positional relationship, the ear-clip earphone can form a fully in-ear earphone.

[0188] For example, in a first relative positional relationship, one of the at least two elastic shells 120 has a gap with the wearer's ear canal, where the ear canal is not sealed. In a second relative positional relationship, the other elastic shell 120 is sealed with the wearer's ear canal. As an example, in the first relative positional relationship, the ear-clip earphone can form an open-back earphone; in the second relative positional relationship, the ear-clip earphone can form a fully in-ear earphone. As yet another example, in the first relative positional relationship, the ear-clip earphone can form a semi-in-ear earphone; in the second relative positional relationship, the ear-clip earphone can form a fully in-ear earphone.

[0189] In this embodiment of the disclosure, the number of at least two elastic shells 120 is not limited. For example, the number of at least two elastic shells 120 can be at least three, at least four, at least five, etc.

[0190] In some examples, the number of elastic shells 120 can be at least three, one of the at least three elastic shells 120 can be used to have a first relative positional relationship with the wearer's ear canal, another of the at least three elastic shells 120 can be used to have a second relative positional relationship with the wearer's ear canal, and yet another of the at least three elastic shells 120 can be used to have a third relative positional relationship with the wearer's ear canal.

[0191] Here, in the first relative positional relationship, the ear clip-on headphones can form an open-back headphone; in the second relative positional relationship, the ear clip-on headphones can form a semi-in-ear headphone; and in the third relative positional relationship, the ear clip-on headphones can form a fully in-ear headphone.

[0192] Of course, in the first relative positional relationship, the ear clip-on earphone can also form a semi-in-ear earphone, where the gap between one of the three elastic shells 120 and the wearer's ear canal can be relatively large; in the second relative positional relationship, the ear clip-on earphone can form a semi-in-ear earphone, where the gap between the other of the three elastic shells 120 and the wearer's ear canal can be relatively large; in the third relative positional relationship, the ear clip-on earphone can form a fully in-ear earphone.

[0193] In the embodiments of this disclosure, the implementation method of different elastic shells 120 having different relative positional relationships is not limited. For example, different elastic shells 120 may have different relative positional relationships through different shapes, different sizes, different wearing positions, etc. This disclosure does not limit this. For example, the shape of one of the at least two elastic shells 120 is different from the shape of the other elastic shell 120. As an example, in the wearing state, the second sound outlet 126 of one of the at least two elastic shells 120 may extend towards the non-ear canal side, and the second sound outlet 126 of the other elastic shell 120 may extend towards the ear canal side, thereby giving one elastic shell 120 and the other elastic shell 120 different relative positional relationships with the wearer's ear canal.

[0194] In some implementations of the embodiments of this disclosure, at least two elastic shells 120 may include a first elastic shell 1201 and a second elastic shell 1202; when the first elastic shell 1201 is wrapped around the support shell 110, a first distance L1 may be present between the first outer end portion 127 on the periphery of the second sound outlet 126 of the first elastic shell 1201 and the first outer end face 116 on the periphery of the first sound outlet 111, such as... Figure 11 and Figure 15As shown; when the second elastic shell 1202 is wrapped outside the support shell 110, there is a second distance L2 between the first outer end 127 on the periphery of the second sound outlet 126 of the second elastic shell 1202 and the first outer end face 116 on the periphery of the first sound outlet 111, as shown. Figure 12 As shown; wherein, the first spacing L1 can be smaller than the second spacing L2; in the wearing state, the first outer end 127 of the second elastic shell 1202 can be closer to the ear canal than the first outer end 127 of the first elastic shell 1201, so that the first elastic shell 1201 and the second elastic shell 1202 can have different external dimensions through different first outer ends 127, so as to have different relative positional relationships with the ear canal.

[0195] In some examples, the first elastic shell 1201 can be used to have a first relative positional relationship with the wearer's ear canal; the second elastic shell 1202 can be used to have a second relative positional relationship with the wearer's ear canal. Of course, in other examples, the first elastic shell 1201 can be used to have a second relative positional relationship with the wearer's ear canal; the second elastic shell 1202 can be used to have a first relative positional relationship with the middle of the wearer's ear canal.

[0196] In this implementation, at least two elastic shells 120 may further include a third elastic shell 1203 and a fourth elastic shell 1204; when the third elastic shell 1203 is wrapped around the support shell 110, a third distance L3 may be present between the first outer end 127 on the periphery of the second sound outlet 126 of the third elastic shell 1203 and the first outer end face 116 on the periphery of the first sound outlet 111, such as... Figure 13 As shown; when the fourth elastic shell 1204 is wrapped outside the support shell 110, a fourth distance L4 may be present between the first outer end 127 on the periphery of the second sound outlet 126 of the fourth elastic shell 1204 and the first outer end face 116 on the periphery of the first sound outlet 111, as shown. Figure 14 and Figure 16 As shown; where the third spacing L3 can be smaller than the fourth spacing L4, and the second spacing L2 can be smaller than the third spacing L3.

[0197] Here, the lengths of the first outer ends 127 of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can increase sequentially. Of course, in other examples, at least two elastic shells 120 may also include one of the third elastic shell 1203 and the fourth elastic shell 1204. Alternatively, at least two elastic shells 120 may include any two or three of the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204.

[0198] In this implementation, the value of the first spacing L1 is not limited. For example, the value of the first spacing L1 can be 1mm to 1.5mm, 1mm to 1.3mm, 1.3mm to 1.5mm, etc.

[0199] The value of the second spacing L2 is not limited. For example, the value of the second spacing L2 can be 1.5mm to 2mm, 1.5mm to 1.7mm, 1.7mm to 2mm, etc.

[0200] The value of the third spacing L3 is not limited. For example, the value of the third spacing L3 can be 2.1mm to 2.9mm, 2.3mm to 2.7mm, 2.5mm to 2.6mm, etc.

[0201] The value of the fourth spacing L4 is not limited. For example, the value of the fourth spacing L4 can be 3mm to 3.5mm, 3mm to 3.2mm, 3.2mm to 3.5mm, etc.

[0202] In this implementation, the relative positional relationship between the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203 and the fourth elastic shell 1204 and the ear canal is not limited.

[0203] For example, the first elastic shell 1201 can be used to have a first relative positional relationship with the wearer's ear canal; the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can be used to have a second relative positional relationship with the wearer's ear canal. As another example, the first elastic shell 1201, the second elastic shell 1202, and the third elastic shell 1203 can be used to have a first relative positional relationship with the wearer's ear canal; the fourth elastic shell 1204 can be used to have a second relative positional relationship with the wearer's ear canal. As yet another example, the first elastic shell 1201 and the second elastic shell 1202 can be used to have a first relative positional relationship with the wearer's ear canal; the third elastic shell 1203 and the fourth elastic shell 1204 can be used to have a second relative positional relationship with the wearer's ear canal.

[0204] In some examples, a first elastic shell 1201 may be used to have a first relative positional relationship with the wearer's ear canal; a second elastic shell 1202 and / or a third elastic shell 1203 may be used to have a second relative positional relationship with the wearer's ear canal; a fourth elastic shell 1204 may be used to have a third relative positional relationship with the wearer's ear canal; in the first relative positional relationship, the ear clip-on earphone may form an open-back earphone; in the second relative positional relationship, the ear clip-on earphone may form a semi-in-ear earphone; in the third relative positional relationship, the ear clip-on earphone may form a fully in-ear earphone.

[0205] Here, the second elastic shell 1202 can be used to have a second relative positional relationship with the wearer's ear canal, and the third elastic shell 1203 can be used to have a second relative positional relationship or a third relative positional relationship with the wearer's ear canal. Alternatively, the third elastic shell 1203 can be used to have a second relative positional relationship with the wearer's ear canal, and the second elastic shell 1202 can be used to have a second relative positional relationship or a first relative positional relationship with the wearer's ear canal.

[0206] In this implementation, the first elastic shell 1201 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the first elastic shell 1201 has a first distance M1 between it and the middle of the wearer's ear canal. Figure 22 and Figure 23 As shown; the second elastic shell 1202 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the second elastic shell 1202 has a second distance M2 between it and the middle of the wearer's ear canal, as shown. Figure 24 As shown; the third elastic shell 1203 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the third elastic shell 1203 has a third distance M3 between it and the middle of the wearer's ear canal, as shown. Figure 25 As shown; the fourth elastic shell 1204 is wrapped around the support shell 110. In the wearing state, the second sound outlet 126 of the fourth elastic shell 1204 has a fourth distance M4 between it and the middle of the wearer's ear canal, as shown. Figure 26 As shown; the third distance M3 can be greater than the fourth distance M4, the second distance M2 can be greater than the third distance M3, and the first distance M1 can be greater than the second distance M2.

[0207] In this implementation, such as Figure 15 and Figure 16 As shown, the elastic shell 120 may include a first inner surface 129 disposed opposite to the first outer end face 116 surrounding the first sound outlet 111; the second sound outlet 126 may be disposed along the first extending direction Q; the first elastic shell 1201 may have a first cross section E1 perpendicular to the first extending direction Q and passing through the first inner surface 129, such as... Figure 11 and Figure 17 As shown, the second elastic shell 1202 has a second cross section E2 perpendicular to the first extending direction Q and passing through the first inner surface 129, as... Figure 12 and Figure 18 As shown; the third elastic shell 1203 has a third cross section E3 perpendicular to the first extending direction Q and passing through the first inner surface 129, as... Figure 13 and Figure 19 As shown; the fourth elastic shell 1204 has a fourth cross section E4 perpendicular to the first extending direction Q and passing through the first inner surface 129, as... Figure 14 and Figure 20As shown; the outer dimensions of the first cross-section E1 can be smaller than the outer dimensions of the second cross-section E2, the outer dimensions of the second cross-section E2 can be smaller than the outer dimensions of the third cross-section E3, and the outer dimensions of the third cross-section E3 can be smaller than the outer dimensions of the fourth cross-section E4, thereby giving the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 different positional relationships with the wearer's ear canal through the gradually increasing outer dimensions of their cross-sections; here, the tightness of the fit between the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 and the ear canal gradually increases as the outer dimensions of their cross-sections gradually increase.

[0208] Here, the external dimensions of the first section E1, the second section E2, the third section E3, and the fourth section E4 can gradually increase in one direction, two directions, or multiple directions.

[0209] As an example, in each direction perpendicular to the first extension direction Q, the external dimensions of the first section E1, the second section E2, the third section E3, and the fourth section E4 all gradually increase.

[0210] As another example, in the fourth direction perpendicular to the first extension direction Q, the external dimensions of the first section E1, the second section E2, the third section E3, and the fourth section E4 gradually increase; in the fifth direction perpendicular to the first extension direction Q, the external dimensions of the first section E1, the second section E2, the third section E3, and the fourth section E4 gradually increase; and in the fifth direction perpendicular to the first extension direction Q, the values ​​of the gradually increasing external dimensions of the first section E1, the second section E2, the third section E3, and the fourth section E4 are relatively large.

[0211] In this implementation, the elastic shell 120 may include a first mating portion 121 and a second mating portion 122 disposed opposite to each other in the first direction. The second mating portion 122 may have a second sound outlet 126. The first mating portion 121 and the second shell 200 may have a clamping gap 520. The second mating portion 122 of the first elastic shell 1201 may be used to contact the support shell 110. The second mating portion 122 of the second elastic shell 1202 may be used to have a first sub-second deformation space 1321 between itself and the support shell 110. The second mating portion 122 of the third elastic shell 1203 may be used to have a second sub-second deformation space 1321 between itself and the support shell 110. The second mating part 122 of the fourth elastic shell 1204 can be used to have a third sub-second deformation space 1323 between itself and the support shell 110; the third sub-second deformation space 1323 can be larger than the second sub-second deformation space 1322, and the second sub-second deformation space 1322 can be larger than the first sub-second deformation space 1321; thereby, by whether or not a second deformation space 132 is present and by the different sizes of the second deformation space 132, the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203 and the fourth elastic shell 1204 have different sizes, so as to form different relative positional relationships with the wearer's ear canal.

[0212] In this implementation, the elastic shell 120 may include a first mating portion 121 and a second mating portion 122 disposed opposite to each other in the first direction. The second mating portion 122 may have a second sound outlet 126. The first mating portion 121 and the second shell 200 may have a clamping gap 520. The first mating portion 121 of the first elastic shell 1201 may be used to contact the support shell 110. The dimensions of the first mating portions 121 of the third elastic shell 1203, the fourth elastic shell 1204, and the second elastic shell 1202 may be the same. The first mating portion 121 of the second elastic shell 1202 may have a first deformation space 131 between itself and the support shell 110. Thus, by whether or not the first deformation space 131 is present, the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 may have different dimensions to form different relative positional relationships with the wearer's ear canal.

[0213] In this implementation, the first elastic shell 1201 may have a first maximum size in the first direction, the second elastic shell 1202 may have a second maximum size in the first direction, the third elastic shell 1203 may have a third maximum size in the first direction, and the fourth elastic shell 1204 may have a fourth maximum size in the first direction. The first maximum size may be smaller than the second maximum size, the second maximum size may be smaller than the third maximum size, and the third maximum size may be smaller than the fourth maximum size. By having different maximum sizes in the first direction, the first elastic shell 1201, the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 form different relative positional relationships with the wearer's ear canal.

[0214] The first maximum size, the second maximum size, the third maximum size, and the fourth maximum size have been described in the above embodiments, and will not be repeated here.

[0215] In some implementations of the embodiments of this disclosure, when at least two elastic shells 120 of the first type are wrapped outside the support shell 110, the first type of elastic shell 120 and the wearer's ear canal may have a first relative positional relationship; the number of elastic shells 120 in the first type may be greater than or equal to 1, 2, 3, etc.; when at least two elastic shells 120 of the second type are wrapped outside the support shell 110, the second type of elastic shell 120 and the wearer's ear canal may have a second relative positional relationship; the number of elastic shells 120 in the second type may be greater than or equal to 1, 2, 3, etc.

[0216] In this implementation, the specific number of the first type of elastic shell 120 and the second type of elastic shell 120 is not limited. In some examples, at least two elastic shells 120 may include a first elastic shell 1201, a second elastic shell 1202, a third elastic shell 1203, and a fourth elastic shell 1204. The first elastic shell 1201 can be a first type of elastic shell 120, and the second elastic shell 1202, the third elastic shell 1203, and the fourth elastic shell 1204 can be second type of elastic shells 120. Alternatively, the first elastic shell 1201 and the second elastic shell 1202 can be first type of elastic shells 120, and the third elastic shell 1203 and the fourth elastic shell 1204 can be second type of elastic shells 120. Or, the first elastic shell 1201, the second elastic shell 1202, and the third elastic shell 1203 can be first type of elastic shells 120, and the fourth elastic shell 1204 can be second type of elastic shell 120.

[0217] In this implementation, when the first type of elastic shell 120 is wrapped around the support shell 110, there may be a first distance between the first outer end 127 on the periphery of the second sound outlet 126 of the first type of elastic shell 120 and the first outer end face 116 on the periphery of the first sound outlet 111; when the second type of elastic shell 120 is wrapped around the support shell 110, there may be a second distance between the first outer end 127 on the periphery of the second sound outlet 126 of the second type of elastic shell 120 and the first outer end face 116 on the periphery of the first sound outlet 111; wherein, the first distance may be less than the second distance. By setting the distance between the first outer end 127 and the first outer end face 116 of the first type of elastic shell 120 to be relatively small, the distance between the first outer end 127 of the first type of elastic shell 120 and the middle of the wearer's ear canal can be set relatively far; by setting the distance between the first outer end 127 and the first outer end face 116 of the second type of elastic shell 120 to be relatively large, the distance between the first outer end 127 of the second type of elastic shell 120 and the middle of the wearer's ear canal can be set relatively close.

[0218] In some examples, such as Figure 11 and Figure 15 As shown, a first distance L1 may exist between the first outer end 127 on the periphery of the second sound outlet 126 of the first elastic shell 1201 and the first outer end face 116 on the periphery of the first sound outlet 111, such as... Figure 12 As shown, a second distance L2 may be present between the first outer end portion 127 on the periphery of the second sound outlet 126 of the second elastic shell 1202 and the first outer end face 116 on the periphery of the first sound outlet 111, such as... Figure 13 As shown, a third distance L3 may be present between the first outer end 127 on the periphery of the second sound outlet 126 of the third elastic shell 1203 and the first outer end face 116 on the periphery of the first sound outlet 111, such as... Figure 14 As shown, a fourth distance L4 may be present between the first outer end 127 on the periphery of the second sound outlet 126 of the fourth elastic shell 1204 and the first outer end face 116 on the periphery of the first sound outlet 111.

[0219] Spacing one may include a first spacing L1, and spacing two may include a second spacing L2, a third spacing L3, and a fourth spacing L4. Alternatively, spacing one may include a first spacing L1 and a second spacing L2, and spacing two may include a third spacing L3 and a fourth spacing L4. Alternatively, spacing one may include a first spacing L1, a second spacing L2, and a third spacing L3, and spacing two may include a fourth spacing L4.

[0220] In this implementation, the first type of elastic shell 120 is wrapped around the support shell 110. In the wearing state, the first outer end 127 on the periphery of the second sound outlet 126 of the first type of elastic shell 120 can be at a distance of one from the middle of the wearer's ear canal. The second type of elastic shell 120 is wrapped around the support shell 110. In the wearing state, the first outer end 127 on the periphery of the second sound outlet 126 of the second type of elastic shell 120 can be at a distance of two from the middle of the wearer's ear canal. The distance one can be greater than the distance two. By making the distance one greater than the distance two, the first outer end 127 of the first type of elastic shell 120 can be relatively far from the middle of the wearer's ear canal, and the first outer end 127 of the second type of elastic shell 120 can be relatively close to the middle of the wearer's ear canal.

[0221] In some examples, when worn, the first outer end 127 on the periphery of the second sound outlet 126 of the first elastic shell 1201 can have a first distance M1 with the middle of the wearer's ear canal, such as... Figure 22 and Figure 23 As shown; the first outer end 127 on the periphery of the second sound outlet 126 of the second elastic shell 1202 can have a second distance M2 with the middle of the wearer's ear canal, such as Figure 24 As shown; the first outer end 127 on the periphery of the second sound outlet 126 of the third elastic shell 1203 can have a third distance M3 with the middle of the wearer's ear canal, such as Figure 25 As shown; the first outer end 127 on the periphery of the second sound outlet 126 of the fourth elastic shell 1204 can have a fourth distance M4 with the middle of the wearer's ear canal, such as Figure 26 As shown.

[0222] Distance 1 can include a first distance M1, and distance 2 can include a second distance M2, a third distance M3, and a fourth distance M4. Alternatively, distance 1 can include a first distance M1 and a second distance M2, and distance 2 can include a third distance M3 and a fourth distance M4. Alternatively, distance 1 can include a first distance M1, a second distance M2, and a third distance M3, and distance 2 can include a fourth distance M4.

[0223] In this implementation, the elastic shell 120 may include a first inner surface 129 disposed opposite to the first outer end face 116 surrounding the first sound outlet 111; the second sound outlet 126 may be disposed along the first extending direction Q; the first type of elastic shell 120 may have a first type of cross section perpendicular to the first extending direction Q and passing through the first inner surface 129, and the second type of elastic shell 120 may have a second type of cross section perpendicular to the first extending direction Q and passing through the first inner surface 129; the outer dimensions of the first type of cross section may be smaller than the outer dimensions of the second type of cross section. By making the outer dimensions of the first type of cross section smaller than the outer dimensions of the second type of cross section, the first type of elastic shell 120 can fit more loosely with the ear canal, and the second type of elastic shell 120 can fit more tightly with the ear canal.

[0224] Here, the first extending direction Q can be perpendicular to the first inner surface 129. Of course, the first extending direction Q can also be substantially perpendicular to the first inner surface 129.

[0225] Here, the first inner surface 129 and the first outer end face 116 can be parallel or substantially parallel.

[0226] Here, the external dimensions of the second type of cross-section can be larger than those of the first type of cross-section in one direction, two directions, or multiple directions.

[0227] For example, in each direction perpendicular to the first extension direction Q, the external dimensions of the second type of cross section can be larger than those of the first type of cross section.

[0228] For example, the external dimensions of the second type of cross-section may have a first difference with the external dimensions of the first type of cross-section in the fourth direction, and the external dimensions of the second type of cross-section may have a second difference with the external dimensions of the first type of cross-section in the fifth direction; the fourth and fifth directions are perpendicular to the first extension direction Q, respectively.

[0229] The first difference and the second difference can be the same or different. As an example, the second difference can be greater than the first difference. In other words, the external dimensions of the second type of cross-section differ more from those of the first type of cross-section in the fifth direction and less in the fourth direction.

[0230] In some examples, such as Figure 17 As shown, the first elastic shell 1201 may have a first cross section E1 perpendicular to the first extending direction Q and passing through the first inner surface 129, such as... Figure 18 As shown, the second elastic shell 1202 may have a second cross section E2 perpendicular to the first extending direction Q and passing through the first inner surface 129; as Figure 19 As shown, the third elastic shell 1203 may have a third cross section E3 perpendicular to the first extending direction Q and passing through the first inner surface 129; as Figure 20As shown, the fourth elastic shell 1204 may have a fourth cross section E4 that is perpendicular to the first extending direction Q and passes through the first inner surface 129.

[0231] The first type of cross section may include a first cross section E1. The second type of cross section may include a second cross section E2, a third cross section E3, and a fourth cross section E4. Alternatively, the first type of cross section may include a first cross section E1 and a second cross section E2. The second type of cross section may include a third cross section E3 and a fourth cross section E4. Alternatively, the first type of cross section may include a first cross section E1. The second type of cross section may include a second cross section E2, a third cross section E3, and a fourth cross section E4.

[0232] In this implementation, the support shell 110 may include a first half-shell 103 and a second half-shell 104 disposed opposite to each other in the second direction; the second direction may be perpendicular to the first direction; and the fourth direction may have a second included angle K2 with the second direction.

[0233] The value of the second included angle K2 is not limited. For example, the second included angle K2 can be 35 degrees to 40 degrees, 36 degrees to 39 degrees, 37 degrees to 38 degrees, etc.

[0234] In this implementation, the elastic shell 120 may include a first mating part 121 and a second mating part 122 disposed opposite to each other in the first direction. The second mating part 122 may have a second sound outlet 126, and the first mating part 121 and the second shell 200 may have a clamping gap 520. The outer dimensions of the second mating part 122 of the first type of elastic shell 120 may be smaller than those of the second mating part 122 of the second type of elastic shell 120, thereby achieving different outer dimensions for the first type of elastic shell 120 and the second type of elastic shell 120 through the second mating parts 122 with different outer dimensions.

[0235] The implementation of the second mating part 122 of the first type of elastic shell 120 and the second mating part 122 of the second type of elastic shell 120 having different external dimensions is not limited.

[0236] For example, the second mating portion 122 of the first type of elastic shell 120 and the second mating portion 122 of the second type of elastic shell 120 can be used to contact the support shell 110. The thickness of the second mating portion 122 of the first type of elastic shell 120 can be less than the thickness of the second mating portion 122 of the second type of elastic shell 120; thus, different thicknesses result in different external dimensions.

[0237] For example, the second mating part 122 of the first type of elastic shell 120 can be used to contact the support shell 110; the second mating part 122 of the second type of elastic shell 120 can be used to be spaced apart from the support shell 110 and form a second deformation space 132; thus, different external dimensions are formed by whether or not the second deformation space 132 is provided.

[0238] For example, the second mating portion 122 of the first type of elastic shell 120 can be used to be spaced apart from the support shell 110 and form a first type of second deformation space 132; the second mating portion 122 of the second type of elastic shell 120 can be used to be spaced apart from the support shell 110 and form a second type of second deformation space 132; the first type of second deformation space 132 is smaller than the second type of second deformation space 132; thus, different external dimensions are achieved by varying the size of the second deformation space 132.

[0239] In some examples, such as Figure 11 and Figure 15 In the middle, the second mating part 122 of the first elastic shell 1201 is configured to contact the support shell 110, such as Figure 12 As shown, the second mating portion 122 of the second elastic shell 1202 is used to have a first sub-second deformation space 1321 between itself and the supporting shell 110; as Figure 13 As shown, the second mating portion 122 of the third elastic shell 1203 is used to have a second sub-second deformation space 1322 between itself and the supporting shell 110; as Figure 14 and Figure 16 As shown, the second mating part 122 of the fourth elastic shell 1204 is used to have a third sub-second deformation space 1323 between itself and the support shell 110. The third sub-second deformation space 1323 is larger than the second sub-second deformation space 1322, and the second sub-second deformation space 1322 is larger than the first sub-second deformation space 1321.

[0240] Here, the first type of elastic shell 120 may include a first elastic shell 1201, and the second type of elastic shell 120 may include a second elastic shell 1202, a third elastic shell 1203, and a fourth elastic shell 1204. Alternatively, the first type of elastic shell 120 may include a first elastic shell 1201 and a second elastic shell 1202, and the second type of elastic shell 120 may include a third elastic shell 1203 and a fourth elastic shell 1204. Alternatively, the first type of elastic shell 120 may include a first elastic shell 1201, and the second type of elastic shell 120 may include a second elastic shell 1202, a third elastic shell 1203, and a fourth elastic shell 1204.
