Description

Technical Field

[0001] The present invention relates to the technical field related to earphones, in particular to a semi-in-ear earphone. Background Art

[0002] As is known to all, semi-in-ear headphones are a type of headphone whose design is between in-ear headphones and open-ear headphones. This type of headphone is usually not fully inserted into the ear, but partially inserted into the ear canal. It usually has the following characteristics: Comfort: Since it is not fully inserted into the ear canal, it is often more comfortable and suitable for long-term wear; Sound quality: Due to design reasons, this type of headphone can usually provide better sound quality, especially in mid- and high-frequency performance; Transparency: Compared with in-ear headphones, semi-in-ear headphones are slightly insufficient in isolating external sounds, but they allow users to still hear some surrounding sounds while enjoying music, which is very practical in some occasions; Portability: Semi-in-ear headphones are usually also lighter and easier to carry.

[0003] For example, the patent with announcement number CN118890577A, announcement date November 1, 2024, and titled "A Semi-In-Ear Headphone" includes a rod with a built-in main control circuit board, a head with a built-in speaker, a battery, and a conductive component, the conductive component includes: a conductive circuit board located between the battery and the speaker, a front FPC circuit board located on the inner wall of the head, a terminal seat located at the top of the rod, and a terminal circuit board located above the terminal seat and electrically connected to the terminal seat; a terminal plug is provided at the top of the main control circuit board, and the electrical connection between the conductive component and the main control circuit board is achieved through the docking of the terminal plug and the terminal seat; a top through hole is provided at the top of the rod, and a touch head is provided at the top through hole. After adopting the above technical solution, in the assembly process of the present invention, after the conductive group is first connected to the speaker and the battery, there is no need to use manual wire welding in the subsequent assembly process. It is only necessary to assemble each component to the specified position, which greatly improves the assembly efficiency and improves the yield rate of the product.

[0004] In the prior art, a dustproof net is arranged in the sound outlet of the earphone facing the wearer's ear canal. The dustproof net is used to prevent dust and stains from entering the earphone shell. In order to prevent the dustproof net from being worn out due to exposure, the dustproof net is arranged in a concave manner in the sound outlet. There is a concave part in the sound outlet, and the dust and stains blocked will accumulate in the concave part, which not only affects the music playback, but also breeds bacteria and other harmful substances. However, it is currently inconvenient to clean the concave part, and a needle-like tool needs to be inserted into the concave part for cleaning. This cleaning method not only fails to clean thoroughly, but may also damage the dustproof net. Summary of the invention

[0005] The purpose of the present invention is to provide a semi-in-ear earphone to solve the technical problems in the related art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] As mentioned above, the elastic body is in a curved ring structure, and its shape is adapted to the shape of the main body shell.

[0009] As mentioned above, the elastic body is in an outwardly arched state on the main body shell.

[0010] As mentioned above, the transmission member includes a first transmission rod connected to the elastic body and a support frame fixed to the dustproof net, the support frame is connected to a second transmission rod, power is transmitted between the first transmission rod and the second transmission rod through a third transmission rod, and the third transmission rod is swingably arranged on the main body.

[0011] As mentioned above, when the dustproof net extends out of the sound outlet along the sound emitting direction, the swing direction of the third transmission rod is the first direction, and when the dustproof net retracts into the sound outlet along the sound emitting direction, the swing direction of the third transmission rod is the second direction.

[0012] As mentioned above, the first transmission rod is provided with an arc-shaped groove on the side facing the sound output direction, and the third transmission rod is provided with an arc-shaped head at the end corresponding to the first transmission rod, and the arc-shaped groove and the arc-shaped head are rotatably connected in a detachable manner; the elastomer is provided with two extrusion positions: the first position, when wearing the earphones, the elastomer is extruded along the direction of the wearer's ear canal, the first transmission rod drives the arc-shaped groove to deviate from the arc-shaped head, and one side of the first transmission rod restricts the swing of the third transmission rod along the first direction; the second position, when cleaning the sound outlet, the elastomer is extruded along the direction parallel to the length of the first transmission rod, and the first transmission rod drives the third transmission rod to swing based on the rotation cooperation of the arc-shaped groove and the arc-shaped head.

[0015] As mentioned above, the baffle includes a guiding section and a blocking section. During the stroke of squeezing the elastomer from the first position, the first transmission rod gradually moves to the blocking section under the guiding action of the guiding section. When the first transmission rod abuts against the blocking section, the blocking section limits the swinging of the first transmission rod along the second direction.

[0016] As mentioned above, there are two transmission parts, which are arranged at two positions opposite to the elastic body; an anti-accidental collision mechanism is provided between the two transmission parts and the dustproof net. When only one transmission part is subjected to the force from the elastic body, the dustproof net does not extend out of the sound outlet along the sound output direction.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 6 The present invention is further described in detail.

[0028] An embodiment of the present invention provides a semi-in-ear earphone, including an earphone body 1, a dustproof net 14 is arranged at the sound outlet 13 of the body 1, and the dustproof net 14 is arranged in a concave manner at the sound outlet 13. An elastomer 15 is provided on the outer shell part of the body 1 located at the sound outlet 13, and a transmission part is provided between the elastomer 15 and the dustproof net 14; when the sound outlet 13 needs to be cleaned, the elastomer 15 is pressed to cause elastic deformation, and the dustproof net 14 extends along the sound outlet direction of the sound outlet 13 based on the elastic deformation force of the elastomer 15.

[0029] Specifically, the body 1 of the semi-in-ear earphone includes a front cavity shell 10, a rear cavity shell 11 and an earphone handle 12. The front cavity shell 10 fits against the concha cavity wall of the wearer's ear. The front cavity shell 10 and the rear cavity shell 11 are combined to form a junction boundary. A sound unit (not specifically shown in the figure) is arranged in the cavity formed between the two. The earphone handle 12 is connected to the rear cavity shell 11. The sound outlet 13 is on the front cavity shell 10 and extends into the external auditory canal to a certain depth. When the earphone plays sound, the sound enters the external auditory canal through the sound outlet 13. A dustproof net 14 is arranged at the sound outlet 13. The dustproof net 14 is used to prevent dust and stains from entering the interior of the body 1. During use, in order to protect the dustproof net 14 from wear and tear, the dustproof net 14 will be arranged inside the sound outlet 13 (recessed arrangement), that is, there is a certain distance between the open end of the sound outlet 13 and the dustproof net 14, so as to avoid the dustproof net 14 being worn. However, dust and stains will accumulate in the part between the open end of the sound outlet 13 and the dustproof net 14, which will not only affect the music playback over time, but also breed harmful substances such as bacteria. However, it is currently inconvenient to clean the recessed part, and a needle-like tool needs to be inserted into the recessed part for cleaning. This cleaning method not only fails to clean thoroughly, but may also damage the dustproof net 14.

[0030] Based on the above problems, in this embodiment, the dustproof net 14 is arranged to be movable in the sound outlet 13 along the sound outlet direction, and an elastic body 15 (such as rubber) is correspondingly arranged on the front cavity shell 10, and a transmission member is arranged between the elastic body 15 and the dustproof net 14. In this way, when it is necessary to clean the dust and stains accumulated in the part between the open end of the sound outlet 13 and the dustproof net 14, the elastic body 15 can be squeezed. After the elastic body 15 is elastically deformed, the power is transmitted to the dustproof net 14 through the transmission member, so that the dustproof net 14 extends out of a part of the sound outlet 13 along the sound outlet direction, and the accumulated dust and stains are pushed out, and then a paper towel is used to clean the dust and stains attached to the dustproof net 14. The dust and stains on the sound outlet 13 can be wiped clean, and the transmission part can transmit the force of the elastic deformation of the elastomer 15 to the dustproof net 14, that is, the deformation direction of the elastomer 15 is consistent with the moving direction of the dustproof net 14, and a long strip transmission rod is arranged between the two. The length direction of the transmission rod is consistent with the deformation direction of the elastomer 15. The power transmission method and transmission structure between the two components are all existing technologies and will not be elaborated on here. In addition, the cleaning method of the dust and stains accumulated in the sound outlet 13 in this embodiment is more convenient than cleaning by using a needle-like tool to reach into the concave part. The cleaning effect is better.

[0031] Preferably, the elastic body 15 is in a curved ring structure, and its shape is adapted to the shape of the outer shell of the main body 1; the elastic body 15 is in an outwardly arched state on the outer shell of the main body 1.

[0032] Specifically, according to the structural characteristics of the elastomer 15 and the arrangement of the elastomer 15 on the front cavity shell 10, the position of the transmission part can be arranged arbitrarily, preferably in a position that is not easily touched by mistake, so as to reduce the situation where the dustproof net 14 pushes dust and stains into the external auditory canal due to accidental touch. More preferably, the elastomer 15 is in a state of arching outward on the front cavity shell 10 (that is, deviating from the direction of the front cavity shell 10). In this way, when wearing the earphone, the elastomer 15 can be elastically deformed by the squeezing of the external auditory canal wall, but the degree of elastic deformation is less than the degree of deformation of the elastomer 15 when the dust and stains on the sound outlet 13 are cleaned. In this way, there is elastic contact between the outer shell of the main body 1 and the external auditory canal wall. Compared with the hard contact between the outer shell of the main body 1 and the external auditory canal wall, the wearing comfort of the earphone can be improved, and the elastic deformation of the elastomer 15 can make the fit between the earphone and the external auditory canal wall higher, and further improve the sound insulation and noise reduction effects.

[0033] Preferably, the transmission member includes a first transmission rod 16 connected to the elastomer 15 and a support frame 17 fixed to the dustproof net 14, and a second transmission rod 18 is connected to the support frame 17. Power is transmitted between the first transmission rod 16 and the second transmission rod 18 via a third transmission rod 19, and the third transmission rod 19 is swingably arranged on the main body 1; when the dustproof net 14 extends out of the sound outlet 13 along the sound output direction, the swing direction of the third transmission rod 19 is the first direction, and when the dustproof net 14 retracts into the sound outlet 13 along the sound output direction, the swing direction of the third transmission rod 19 is the second direction.

[0034] Specifically, due to the external structure of the front cavity shell 10 (the external structure of the front cavity shell 10 of the semi-in-ear earphone is the prior art and will not be elaborated on here), the structure of the elastomer 15 needs to adapt to the external shape of the front cavity shell 10, so that the deformation direction of the elastomer 15 under extrusion is difficult to be consistent with the moving direction of the dustproof net 14. Therefore, in this embodiment, since the dustproof net 14 is relatively thin, the support frame 17 fixed to the dustproof net 14 can provide rigid support for the dustproof net 14, and then a first transmission rod 16 is arranged on the elastomer 15, and a second transmission rod 18 is arranged on the support frame 17. Power is transmitted between the first transmission rod 16 and the second transmission rod 18 through a third transmission rod 19, and the third transmission rod 19 is arranged to swing in the front cavity shell 10, that is, when the first transmission rod 16 is pushed by the deformation of the elastomer 15 during operation, a pushing effect can be generated on one end of the third transmission rod 19, and the pushing effect enables the third transmission rod 19 to swing along the swing axis connected to the front cavity shell 10. When the second transmission rod 18 is swung, the swing of the other end of the third transmission rod 19 will push the second transmission rod 18 to move, and the second transmission rod 18 can push the support frame 17 to move, so that the power transmission between the elastic body 15 and the dustproof net 14 can be realized. In the stroke of the dustproof net 14 extending out of the sound outlet 13 along the sound outlet direction, the swing direction of the third transmission rod 19 is the first direction, and in the stroke of the dustproof net 14 retracting into the sound outlet 13 along the sound outlet direction, the swing direction of the third transmission rod 19 is the second direction. Since the third transmission rod 19 is swingingly arranged, in order to make the reciprocating swing of the third transmission rod 19 drive the second transmission rod 18 to move, a swinging groove 22 that is matched and connected with the other end of the third transmission rod 19 is provided at one end of the second transmission rod 18 away from the support frame 17, and the other end of the third transmission rod 19 can rotate or slide in the swinging groove 22, but the two will not separate, that is, the two side walls of the swinging groove 22 are always on the swinging path of the other end of the third transmission rod 19.

[0035] There is also a connection method between the first transmission rod 16 and one end of the third transmission rod 19. Preferably, the first transmission rod 16 is provided with an arc-shaped groove 20 on the side facing the sound output direction, and the third transmission rod 19 is provided with an arc-shaped head 21 at the end corresponding to the first transmission rod 16, and the arc-shaped groove 20 and the arc-shaped head 21 are rotatably connected in a detachable manner; the elastomer 15 has two extrusion positions: the first position 23, when wearing the earphones, the elastomer 15 is extruded along the direction of the wearer's ear canal, the first transmission rod 16 drives the arc-shaped groove 20 to deviate from the arc-shaped head 21, and one side of the first transmission rod 16 restricts the swing of the third transmission rod 19 along the first direction; the second position 24, when cleaning the sound outlet 13, the elastomer 15 is extruded along the length direction parallel to the first transmission rod 16, and the first transmission rod 16 drives the third transmission rod 19 to swing based on the rotation cooperation of the arc-shaped groove 20 and the arc-shaped head 21.

[0036] That is, when wearing the earphone, the extrusion position of the elastic body 15 by the external auditory canal should be distinguished from the position of the elastic body 15 when cleaning the sound outlet 13. At this time, there is no need to drive the dustproof net 14 to move to avoid pushing the dust and stains accumulated in the sound outlet 13 into the external auditory canal. As can be seen from the above, when wearing the earphone, the first transmission rod 16 should not generate a force on one end of the third transmission rod 19, that is, the connection position of the first transmission rod 16 and one end of the third transmission rod 19 is set on the side of the first transmission rod 16 facing the sound outlet 13, and the elastic body 1 The position squeezed by the external auditory canal is also on the side facing the sound outlet 13. When the elastic body 15 is squeezed by the external auditory canal, the first transmission rod 16 can drive the circular arc groove 20 to be disconnected from the circular arc head 21. In the process of wearing the earphone, one side of the first transmission rod 16 abuts against the circular arc head 21. Based on the rebound force of the elastic body 15, the first transmission rod 16 can limit the swing of the third transmission rod 19 along the first direction, thereby preventing the dust and stains in the sound outlet 13 from being pushed into the external auditory canal by the dustproof net 14 to a certain extent.

[0037] Furthermore, a baffle 25 is provided on the main body 1, and when the first transmission rod 16 limits the swing of the third transmission rod 19 along the first direction, the baffle 25 abuts against the other side of the first transmission rod 16; a block 26 is also provided on the main body 1, and when the first transmission rod 16 limits the swing of the third transmission rod 19 along the first direction, the block 26 limits the swing of the third transmission rod 19 along the second direction.

[0038] Specifically, in the aforementioned embodiment, during the wearing process of the earphone, the force provided by the elastomer 15 to the first transmission rod 16 to limit the swing of the third transmission rod 19 along the first direction is an elastic force. Then when the earphone is worn, if the wearer is in motion, the vibration generated will cause the elastic force provided by the elastomer 15 to be insufficient to limit the movement of the dustproof net 14 in the sound outlet 13. There is still a situation where the dust and stains in the sound outlet 13 are pushed into the external auditory canal. Therefore, in this embodiment, a baffle 25 is provided on the other side of the first transmission rod 16, and the baffle 25 is fixedly connected to the front cavity shell 10. In order to facilitate when the first position 23 of the elastomer 15 is squeezed, since the movement direction of the first transmission rod 16 is in the combined direction of the two directions away from the sound outlet and extending into the front cavity shell 10, the baffle 25 is arranged to have a structure including a guide section and a blocking section, that is, in the stroke of squeezing the elastomer 15 from the first position 23, the first transmission rod 16 is Under the guiding action of the guide section, it gradually moves to the blocking section. When the first transmission rod 16 abuts against the blocking section, the blocking section limits the swing of the first transmission rod 16 along the second direction. If one end of the third transmission rod 19 is deflected along the second direction by the force of the first transmission rod 16, the swing of the third transmission rod 19 should also be limited at this time. Because here, although the swing of the third transmission rod 19 along the first direction is restricted, if it is swung along the second direction for a distance under the action of the first transmission rod 16, it can reciprocate based on vibration or change in the deformation of the elastic body 15. Therefore, in this embodiment, when the other side of the first transmission rod 16 is blocked by the blocking section, a stopper 26 is also fixed to the front cavity shell 10. The stopper 26 is used to block the third transmission rod 19 from swinging along the second direction, so that when wearing headphones, the position of the dustproof net 14 can be basically locked, thereby further reducing the situation where dust and stains enter the external auditory canal.

[0039] Preferably, the distance between the swing axis of the third transmission rod 19 and the first transmission rod 16 is smaller than the distance between the third transmission rod 19 and the second transmission rod 18; specifically, due to the limited elastic deformation of the elastomer 15, it should not be arched too much on the front cavity shell 10. Too much arch height will cause uncomfortable wearing. Appropriate arch height can improve wearing comfort and improve the sound insulation and noise reduction effect. Among them, the specific arch height of the elastomer 15 can be set according to actual conditions. Therefore, in this embodiment, the swing axis of the third transmission rod 19 is arranged closer to the first transmission rod 16, which can play a role in amplifying the stroke to ensure that when the elastic body 15 has a small deformation, the dustproof net 14 can smoothly extend a part of the sound outlet 13 to clean dust and stains.

[0040] Furthermore, there are two transmission parts, which are arranged at two positions opposite to the elastic body 15; an anti-accidental collision mechanism is provided between the two transmission parts and the dustproof net 14. When only one transmission part is subjected to the force from the elastic body 15, the dustproof net 14 does not extend out of the sound outlet 13 along the sound output direction.

[0041] Specifically, it is difficult to avoid accidental contact with the earphones during wearing. A separate transmission member is arranged. When the relative position of the elastic body 15 corresponding to the transmission member is accidentally touched (when the relative position of the second position 24 is basically or approximately squeezed), the squeezing effect of the external auditory canal wall on the elastic body 15 becomes smaller or disappears. Then the first transmission rod 16 will be based on the rebound effect of the elastic body 15, so that the arc-shaped groove 20 and the arc-shaped head 21 are connected again. Then, after the accidental contact disappears, the squeezed part of the elastic body 15 rebounds. At this time, the extrusion force direction of the external auditory canal wall on the elastic body 15 is not along the direction when squeezing the first position 23, but is relatively close to the direction when squeezing the second position 24. Then the transmission member will transmit power to the dustproof net 14, causing the dustproof net 14 to move in the sound outlet 13. Therefore, in order to avoid the above situation, in this embodiment, two transmission members are arranged, and the two transmission members are arranged on the elastic body 15 at relative positions, such as relative positions in the width direction, relative positions in the length direction, etc. In this embodiment, basically As for the outer structure of the earphone sound outlet 13, when the earphone is worn, two transmission parts are arranged at two upper and lower positions of the elastomer 15, and two inclined slide grooves 27 are opened on the support frame 17. The arrangement of the two slide grooves 27 is in a trumpet shape, and the opening is facing the sound output direction. A slider 28 is slidably arranged in each slide groove 27, and there is a friction force between each slider 28 and the corresponding slide groove 27. The contact part of the support frame 17 and the front cavity shell 10 also has a friction force, but the component force of the friction force between each slider 28 and the corresponding slide groove 27 along the moving direction of the support frame 17 is smaller than the friction force between the contact part of the support frame 17 and the front cavity shell 10, but the sum of the component forces of the friction force between the two sliders 28 and their respective corresponding slide grooves 27 along the moving direction of the support frame 17 is greater than the friction force between the contact part of the support frame 17 and the front cavity shell 10, wherein each slider 28 is correspondingly connected to a second transmission rod 18, and the end of the second transmission rod 18 connected to the third transmission rod 19 is a cylindrical structure.

[0042] That is to say, for the convenience of description and understanding, the two transmission parts arranged relatively to each other in the upper and lower parts are named A and B respectively. That is, during the wearing process of the earphone, when the B part of the elastomer 15 is accidentally touched and squeezed, the first transmission rod 16 corresponding to this part continues to move in the direction of extending into the front cavity shell 10. Then, the part of the elastomer 15A in its relative position will drive the first transmission rod 16 connected thereto to move in the direction of extending out of the front cavity shell 10 under the action of its own rebound force. When the arc-shaped groove 20 on the first transmission rod 16 is connected to the arc-shaped head 21, the accidental touch disappears, the external auditory canal squeezes the elastomer 15A, the first transmission rod 16 drives the arc-shaped groove 20 to move together, and the arc-shaped groove 20 is connected to the arc-shaped head 21. The arc-shaped head 21 connected to the second transmission rod 18 works together and drives the corresponding third transmission rod 19 to swing. The swing of the third transmission rod 19 drives the second transmission rod 18 to push the support frame 17 to move in the sound outlet 13. However, the friction force between the slider 28 and the slide groove 27 corresponding to the second transmission rod 18 is smaller than the friction force between the support frame 17 and the front cavity shell 10. Then, the movement of the second transmission rod 18 will only drive the slider 28 to slide in the slide groove 27, and the cylindrical structure on the second transmission rod 18 can make the slider 28 deflect smoothly when sliding in the slide groove 27 along the inclined direction. Therefore, the problem of the dustproof net 14 moving in the sound outlet 13 due to accidental contact can be solved.

[0043] When the dust and stains accumulated in the sound outlet 13 need to be cleaned, the earphones are not in the worn state and the elastomer 15 is in the initial state. Then, by pressing the two second positions 24 corresponding to the two transmission parts, the dustproof net 14 can be pushed out of a part of the sound outlet 13 to clean the dust and stains.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.

A semi-in-ear earphone, comprising an earphone body, wherein a dustproof net is arranged at the sound outlet of the body, and the dustproof net is arranged in a concave manner at the sound outlet, characterized in that: An elastic body is provided on the outer shell portion of the main body located at the sound outlet, and a transmission member is provided between the elastic body and the dustproof net; When the sound outlet needs to be cleaned, the elastic body is pressed to cause elastic deformation, and the dustproof net extends along the sound outlet direction of the sound outlet based on the elastic deformation force of the elastic body; The elastic body is in a curved annular structure, and its shape is adapted to the shape of the main body shell; The elastic body is in an outwardly arched state on the main body shell; When wearing the earphones, the elastic body is squeezed by the external auditory canal wall and undergoes elastic deformation, and the degree of elastic deformation is less than the degree of deformation of the elastic body when the elastic body is squeezed when cleaning the dust and stains on the sound outlet; The transmission member includes a first transmission rod connected to the elastic body and a support frame fixed to the dustproof net, the support frame is connected to a second transmission rod, power is transmitted between the first transmission rod and the second transmission rod via a third transmission rod, and the third transmission rod is swingably arranged on the body; When the dustproof net extends out of the sound outlet along the sound outlet direction, the swing direction of the third transmission rod is the first direction, and when the dustproof net retracts into the sound outlet along the sound outlet direction, the swing direction of the third transmission rod is the second direction; A swing groove which is connected with the third transmission rod is provided at one end of the second transmission rod away from the support frame; The first transmission rod is provided with an arc-shaped groove on one side facing the sound output direction, and the third transmission rod is provided with an arc-shaped head at the end corresponding to the first transmission rod, and the arc-shaped groove and the arc-shaped head are rotatably connected in a detachable manner; the elastic body is provided with two extrusion positions: In the first position, when the earphone is worn, the elastic body is squeezed along the ear canal direction of the wearer, the first transmission rod drives the arc-shaped groove to deviate from the arc-shaped head, and one side of the first transmission rod restricts the swing of the third transmission rod along the first direction; In the second position, when the sound outlet is cleaned, the elastic body is squeezed along a direction parallel to the length of the first transmission rod, and the first transmission rod drives the third transmission rod to swing based on the rotation cooperation between the arc-shaped groove and the arc-shaped head.

2. The semi-in-ear earphone according to claim 1, characterized in that: The distance between the swing axis of the third transmission rod and the first transmission rod is smaller than the distance between the swing axis of the third transmission rod and the second transmission rod.

3. The semi-in-ear earphone according to claim 1, characterized in that: The body is provided with a baffle, and when the first transmission rod restricts the swing of the third transmission rod along the first direction, the baffle abuts against the other side of the first transmission rod; The body is also provided with a stopper, and when the first transmission rod limits the swing of the third transmission rod along the first direction, the stopper limits the swing of the third transmission rod along the second direction.

4. The semi-in-ear earphone according to claim 3, characterized in that: The baffle includes a guiding section and a blocking section. During the stroke of squeezing the elastic body from the first position, the first transmission rod gradually moves to the blocking section under the guiding action of the guiding section. When the first transmission rod abuts against the blocking section, the blocking section limits the swinging of the first transmission rod along the second direction.

5. The semi-in-ear earphone according to claim 4, characterized in that: There are two transmission parts, which are arranged at two positions opposite to the elastic body; an anti-accidental collision mechanism is provided between the two transmission parts and the dustproof net. When only one transmission part is subjected to the force from the elastic body, the dustproof net does not extend out of the sound outlet along the sound output direction.
