Description

Technical Field

[0001] This invention relates to the field of headphone technology, specifically to a distributed motherboard low-interference sealed in-ear headphone fixing assembly. Background Technology

[0002] In-ear headphones are a type of headphone that improves sound quality by being inserted into the ear canal and creating a sealed environment. They use rubber tips or custom-made earmolds to achieve this seal. To integrate more functional chips and improve audio processing performance within a limited cavity, some headphones are beginning to adopt a multi-circuit board layout. In current technology, multi-circuit board designs are relatively conventional, with flexible circuit boards used to connect the boards to accommodate miniaturization and complex layout requirements.

[0003] For users with oily ears, wearing in-ear headphones causes prolonged close contact and continuous friction between the ear tip and the inner ear canal skin. This contact stimulates the sebaceous glands in the ear canal to become abnormally active, leading to the secretion of more oily substances. These oils gradually adhere to and soak into the outer surface of the ear tip, forming a low-friction lubricating layer between the earbud and the ear canal wall. This significantly weakens the holding force that the ear tip originally provided through friction. In this state, the headphones are extremely prone to slipping off under the slightest external disturbance, causing them to completely detach from the ear canal. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a distributed motherboard low-interference sealed in-ear headphone fixing assembly, comprising a housing, a sealing sleeve fitted onto the outer wall of the housing, and further comprising: A rotating mechanism is installed on the outer wall of the housing, and the rotating mechanism includes a connecting ring; A connecting mechanism is installed on the outer wall of the housing, and the connecting mechanism includes an arc-shaped plate. The thrust mechanism is installed on the outer wall of the housing and includes a fixed plate. The user inserts the shell into their ear, and a rotating mechanism causes the connecting mechanism and the thrust mechanism to push the sealing sleeve into the ear canal.

[0005] Preferably, the rotating mechanism further includes: A rotating assembly is mounted on the outer wall of the housing. A locking component is installed on the inner wall of the rotating component; The user rotates the locking component to make it turn.

[0006] Preferably, the connecting mechanism further includes: A flip assembly is installed on the outer wall of the housing. A sliding component is mounted on the outer wall of the housing. When the rotating mechanism rotates, the flipping component will rotate simultaneously, and the thrust mechanism will be pushed, causing the thrust mechanism to slide.

[0007] Preferably, the thrust mechanism further includes: The thrust assembly is installed on the outer wall of the sliding assembly; Telescopic assembly, which is installed on the outer wall of the thrust assembly; When the flipping component rotates, the thrust component slides on the outer wall of the sliding component.

[0008] Preferably, the rotating component includes a rotating ring fixedly connected to the outer wall of the connecting ring; The user rotates the rotating ring, causing the locking component to rotate simultaneously.

[0009] Preferably, the locking assembly includes a toothed ring fixedly connected to the outer wall of the housing, an elastic plate fixedly connected to the inner wall of the rotating ring, and a locking block fixedly connected to the elastic plate away from the outer wall of the rotating ring. Among them, the elastic plate is elastic, and it will accumulate potential energy when it is compressed.

[0010] Preferably, the flipping assembly includes a rotating ring fixedly connected to the outer wall of the rotating ring, and a plurality of arc-shaped plates are fixedly connected to the outer wall of the rotating ring; Among them, the arc-shaped plates are arranged in a circular array on the outer wall of the rotating ring.

[0011] Preferably, the sliding component includes several arc-shaped plates two fixedly connected to the outer wall of the housing, and a locking block is fixedly connected to the outer wall of the arc-shaped plates two; Among them, the arc-shaped plate is arranged in a circular array on the arc-shaped plate.

[0012] Preferably, the thrust assembly includes several thrust plates slidably connected to the outer wall of the arc-shaped plate, the outer wall of the thrust plate is fixedly connected to the inner wall of the sealing sleeve, several fixing plates are fixedly connected to the outer wall of the housing, and the outer wall of the thrust plate is rotatably connected to the inner wall of the fixing plate. When the thrust plate rotates away from the housing, it pushes the sealing sleeve to expand outward.

[0013] Preferably, the telescopic component includes a deformable strip fixedly connected to the outer wall of the thrust plate, and a number of claws fixedly connected to the outer wall of the rotating ring; The deformable strip is initially under pressure. When the deformable strip is squeezed, it will bulge out in an arc shape. In the initial state, the arc shape on the deformable strip will fit against the outer wall of the sealing sleeve and lift the sealing sleeve.

[0014] The present invention has the following beneficial effects: (1) By setting a thrust plate, the rotation of the rotating ring will cause the arc plate to contact part of the thrust plate and lift the thrust plate, while the pawl will contact the remaining thrust plate, causing the remaining thrust plate to rotate towards the housing, so that part of the sealing sleeve is pulled back. In this way, the user can change the contact position between the sealing sleeve and the ear canal by rotating the rotating ring, avoiding the long-term contact of a single area of ​​the sealing sleeve with the ear canal and the adhesion of grease, effectively preventing the housing from falling off.

[0015] (2) By setting up a deformation strip, during the rotation of the rotating ring, one of the thrust plates on both sides of the deformation strip is raised upwards and the other thrust plate moves downwards. This causes the arc on the thrust plate to move closer to the thrust plate that is being raised, so that the arc on the deformation strip and the thrust plate cooperate with each other to expand the area where the sealing sleeve is pushed up. In this way, when the thrust plate pushes the rotating ring, it is no longer in line contact. The sealing sleeve pushed out by the thrust plate and the deformation strip is in arc shape, preventing the thrust plate from contacting the ear canal in line contact when pushing out the sealing sleeve, which would cause the ear canal to be under pressure for a long time and cause pain.

[0016] (3) By setting a rotating ring, when the user rotates the rotating ring, four thrust plates will contract inward and four other thrust plates will open outward, controlling the degree of expansion of the sealing sleeve. In this way, the user can adjust the sealing sleeve according to the comfort level, preventing the ear canal cartilage from being compressed for a long time due to the inability to adjust the sealing sleeve after long-term wear.

[0017] (4) By setting the claw, when the user with oily ears needs to adjust the shell, he only needs to rotate the rotating ring to make multiple thrust plates fit into the ear canal. Or when the shell needs to be removed, rotate the rotating ring to make multiple thrust plates fit between the arc plate and the claw to remove the shell. In this way, the user with oily ears will be prevented from stimulating the ear canal to secrete more oil when pushing the ear, which will cause the sealing sleeve to sink deeper during the pushing process. This will cause discomfort when the sealing sleeve is removed later, and in severe cases, pain may occur. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-7 The present invention is a distributed motherboard low-interference sealed in-ear headphone fixing assembly, including a housing 12, a sealing sleeve 13 fitted on the outer wall of the housing 12, and further comprising: Rotating mechanism 2 is installed on the outer wall of housing 12, and rotating mechanism 2 includes connecting ring 211; The connecting mechanism 3 is installed on the outer wall of the housing 12, and the connecting mechanism 3 includes an arc-shaped plate 312; The thrust mechanism 4 is installed on the outer wall of the housing 12 and includes a fixing plate 412. The user inserts the shell 12 into the ear and rotates the rotating mechanism 2 to make the connecting mechanism 3 and the thrust mechanism 4 push the sealing sleeve 13 to fit into the ear canal.

[0023] Rotating mechanism 2 also includes: Rotating component 21 is mounted on the outer wall of housing 12; Locking component 22 is installed on the inner wall of rotating component 21; The user rotates the rotating component 21 to make the locking component 22 rotate.

[0024] Example 2, please refer to Figures 2-10 This invention relates to a distributed motherboard low-interference sealed in-ear headphone fixing assembly. Based on Embodiment 1, the connecting mechanism 3 further includes: A flip assembly 31 is installed on the outer wall of the housing 12. Sliding component 32 is mounted on the outer wall of housing 12; When the rotating mechanism 2 rotates, the flipping component 31 will rotate simultaneously, and the thrust mechanism 4 will be pushed, causing the thrust mechanism 4 to slide.

[0025] The thrust mechanism 4 also includes: Thrust assembly 41 is installed on the outer wall of sliding assembly 32; Telescopic component 42 is installed on the outer wall of thrust component 41; When the flipping component 31 rotates, the thrust component 41 will slide on the outer wall of the sliding component 32.

[0026] The rotating assembly 21 includes a rotating ring 212 that is fixedly connected to the outer wall of the connecting ring 211; The user rotates the rotating ring 212, causing the locking component 22 to rotate simultaneously.

[0027] Locking component 22 includes a toothed ring 223 fixedly connected to the outer wall of housing 12, an elastic plate 221 fixedly connected to the inner wall of rotating ring 212, and a locking block 222 fixedly connected to the elastic plate 221 away from the outer wall of rotating ring 212. Among them, the elastic plate 221 is elastic, and the elastic plate 221 will accumulate potential energy when it is compressed.

[0028] The flipping assembly 31 includes a rotating ring 311 fixedly connected to the outer wall of the rotating ring 212, and a plurality of arc-shaped plates 312 are fixedly connected to the outer wall of the rotating ring 311. Among them, the arc-shaped plate 312 is arranged in a circular array on the outer wall of the rotating ring 311. By setting the rotating ring 311, when the user rotates the rotating ring 311, four thrust plates 411 will retract inward and the other four thrust plates 411 will open outward, controlling the degree of expansion of the sealing sleeve 13. In this way, the user can adjust the sealing sleeve 13 according to the comfort level, preventing the ear canal cartilage from being compressed for a long time due to the inability to adjust the sealing sleeve 13 after long-term wear.

[0029] The sliding component 32 includes several arc-shaped plates 321 fixedly connected to the outer wall of the housing 12, and a locking block 322 is fixedly connected to the outer wall of the arc-shaped plates 321. Among them, the arc-shaped plate 312 is arranged in a circular array on the arc-shaped plate 312.

[0030] The thrust assembly 41 includes several thrust plates 411 that are slidably connected to the outer wall of the arc plate 321. The outer wall of the thrust plate 411 is fixedly connected to the inner wall of the sealing sleeve 13. Several fixing plates 412 are fixedly connected to the outer wall of the housing 12. The outer wall of the thrust plate 411 is rotatably connected to the inner wall of the fixing plate 412. When the thrust plate 411 rotates away from the housing 12, it pushes the sealing sleeve 13 to expand outward. By setting the thrust plate 411, the rotation of the rotating ring 311 will cause the arc plate 312 to contact part of the thrust plate 411 and lift the thrust plate 411. The claw 422 will contact the remaining thrust plate 411, causing the remaining thrust plate 411 to rotate towards the housing 12, so that part of the sealing sleeve 13 is pulled back. In this way, the user can change the contact position between the sealing sleeve 13 and the ear canal by rotating the rotating ring 311, avoiding the long-term contact of a single area of ​​the sealing sleeve 13 with the ear canal and the adhesion of grease, effectively preventing the housing 12 from falling off.

[0031] The telescopic assembly 42 includes a deformable strip 421 fixedly connected to the outer wall of the thrust plate 411, and a number of claws 422 fixedly connected to the outer wall of the rotating ring 311. The deformable strip 421 is initially under pressure. When compressed, the deformable strip 421 will bulge into an arc shape. In the initial state, the arc shape on the deformable strip 421 will fit against the outer wall of the sealing sleeve 13 and lift the sealing sleeve 13. By setting the deformable strip 421, during the rotation of the rotating ring 311, because one of the thrust plates 411 on both sides of the deformable strip 421 is lifted upward and the other thrust plate 411 is moved downward, the arc shape on the thrust plate 411 will move closer to the thrust plate 411 that is being lifted. This allows the arc shape on the deformable strip 421 to cooperate with the thrust plate 411, expanding the area where the sealing sleeve 13 is lifted. In this way, when the thrust plate 411 pushes the rotating ring 311, it is no longer a line contact. The sealing sleeve 13 pushed out by the thrust plate 411 and the deformable strip 421 is in an arc shape, preventing the thrust plate 411 from contacting the ear canal in a line contact manner when it pushes out the sealing sleeve 13, which would cause the ear canal to be under pressure for a long time and cause pain.

[0032] A specific application of this embodiment is as follows: When wearing headphones, the user removes the housing 12 from the headphone compartment, allowing the sealing sleeve 13 to enter the ear canal. When adjustment of the sealing sleeve 13 is needed, the user places their hand on the rotating ring 212 and rotates it. Rotating the rotating ring 212 causes the connecting ring 211 to move. As the connecting ring 211 rotates, the locking block 222 experiences an upward compressive force, causing the elastic plate 221 to bend and accumulate potential energy. With the rotation of the connecting ring 211, the locking block 222 enters the next tooth groove on the toothed ring 223. When the next tooth groove is reached, the elastic plate 221 releases its elastic potential energy, causing the locking block 222 to enter the tooth groove of the toothed ring 223. While the rotating ring 212 rotates, the rotating ring 311 also rotates. During the rotation of the rotating ring 311, the arc-shaped plate 312 contacts the outer wall of the thrust plate 411. As the rotating ring 311 continues to rotate... Rotation causes the thrust plate 411 to be lifted by the arc plate 312, causing the thrust plate 411 to rotate away from the housing 12 around the fixed plate 412. This causes multiple thrust plates 411 to push the sealing sleeve 13 to unfold. During the rotation of the rotating ring 311, the claw 422 will contact other thrust plates 411. As the rotating ring 311 rotates, the thrust plates 411 will rotate towards the housing 12 around the fixed plate 412, causing other parts of the sealing sleeve 13 to be pulled back. The two sides of the lifted thrust plate 411 are the pulled-back thrust plates 411, which will cause the deformation strip 421 to deform. When the arc of the deformation strip 421 is compressed, the bulging arc of the outer wall of the deformation strip 421 will move towards the thrust plate 411 in the lifted state. This will cause the bulging arc of the deformation strip 421 to contact the outer wall of the sealing sleeve 13 and, together with the thrust plate 411, lift up part of the sealing sleeve 13.

[0033] By setting the thrust plate 411, the rotation of the rotating ring 311 will cause the arc plate 312 to contact part of the thrust plate 411 and lift the thrust plate 411 up. The claw 422 will contact the remaining thrust plate 411, causing the remaining thrust plate 411 to rotate towards the housing 12, so that part of the sealing sleeve 13 is pulled back. In this way, the user can change the contact position between the sealing sleeve 13 and the ear canal by rotating the rotating ring 311, avoiding the long-term contact of a single area of ​​the sealing sleeve 13 with the ear canal and the adhesion of grease, effectively preventing the housing 12 from falling off.

[0034] By setting the rotating ring 311, when the user rotates the rotating ring 311, the four thrust plates 411 will retract inward and the other four thrust plates 411 will open outward, controlling the degree of expansion of the sealing sleeve 13. In this way, the user can adjust the sealing sleeve 13 according to the comfort level, preventing the ear canal cartilage from being compressed for a long time due to the inability to adjust the sealing sleeve 13 after long-term wear.

[0035] By setting the deformation strip 421, during the rotation of the rotating ring 311, one of the thrust plates 411 on both sides of the deformation strip 421 lifts upward and the other thrust plate 411 moves downward. This causes the arc on the thrust plate 411 to move closer to the thrust plate 411 that is being lifted, so that the arc on the deformation strip 421 and the thrust plate 411 cooperate with each other to expand the area where the sealing sleeve 13 is pushed up. In this way, when the thrust plate 411 pushes the rotating ring 311, it is no longer a line contact. The sealing sleeve 13 pushed out by the thrust plate 411 and the deformation strip 421 is in an arc shape, preventing the thrust plate 411 from contacting the ear canal in a line contact manner when pushing out the sealing sleeve 13, which would cause the ear canal to be under pressure for a long time and cause pain.

[0036] By setting the claw 422, when an oily-ear user needs to adjust the shell 12, they only need to rotate the rotating ring 212 to make the multiple push plates 411 fit into the ear canal. Or, when the shell 12 needs to be removed, the rotating ring 212 is rotated to make the multiple push plates 411 fit between the arc plate 312 and the claw 422, and the shell 12 can be removed. In this way, it is prevented that when an oily-ear user pushes their ears, it will stimulate the ear canal to secrete more oil, which will cause the sealing sleeve 13 to sink deeper during the pushing process. This will cause discomfort when the sealing sleeve 13 is removed later, and in severe cases, it may cause pain.
