Description

Technical Field

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

[0002] Low-interference distributed motherboard sealed in-ear headphones adopt a distributed circuit architecture, which distributes the main control, wireless radio frequency and audio processing modules on multiple sub-motherboards. With the help of physical isolation and local shielding, electromagnetic crosstalk is greatly reduced, achieving pure audio output and stable wireless transmission. These headphones are often used with flexible in-ear ear tips to form a double seal, which not only optimizes acoustic performance and passive sound insulation, but also prevents moisture and dust from entering.

[0003] Once in-ear headphones are inserted into the ear canal and worn, the continuous changes in head posture and repeated jaw movements during daily activities will cause subtle deformations and relative displacements in the soft tissues around the ear canal. This gradually reduces the friction and clamping force between the headphone cavity and the inner wall of the ear canal, disrupting the initial stable wearing condition. Especially when the range of motion is slightly larger or the wearing time is longer, the headphones are very likely to loosen and fall out of the ear canal, eventually causing the headphones to fall out. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a low-interference distributed motherboard sealed in-ear headphone, comprising a main body, a charging terminal fixedly connected to the outer wall of the main body, a sound outlet fixedly connected to the outer wall of the main body, and further comprising: The support mechanism is slidably disposed on the outer wall of the sound outlet. The support mechanism includes a fixed sleeve that is slidably connected to the outer wall of the sound outlet, and the outer wall of the fixed sleeve is fixedly connected with several bent sleeves. A folding mechanism is fixedly installed on the inner wall of the bending sleeve. The folding mechanism includes an elastic plate fixedly connected to the inner wall of the bending sleeve. A limiting mechanism is installed on the outer wall of the sound outlet. The device includes six bending sleeves arranged in a circular array. The fixing sleeve and bending sleeves are made of soft silicone, while the elastic plate is made of hard silicone. The main body is divided into four independent sub-boards according to signal attributes, which are interconnected by flexible ribbon cables or micro-board connectors. Electromagnetic interference is suppressed by isolating high-frequency harmonics of digital circuits from analog audio signals. The housing is sealed by ultrasonic welding and waterproof rubber rings.

[0005] Preferably, the support mechanism also includes: A sealing assembly is fixedly installed on the outer wall of the fixed sleeve. Pressure assembly, the pressure assembly is installed on the outer wall of the bending sleeve; The sealing component is used to seal the ear canal, while the pressure component relieves contact pressure.

[0006] Preferably, the folding mechanism further includes: The elastic component is installed on the outer wall of the fixed sleeve. A support component is fixedly installed on the outer wall of the bending sleeve. The elastic component restricts the position of the elastic plate, and the support component supports the sealing component.

[0007] Preferably, the limiting mechanism includes: The locking assembly is installed on the outer wall of the sound outlet; The locking component restricts the movement of the elastic plate.

[0008] Preferably, the sealing assembly includes a sealing sleeve that is fixedly connected to the outer wall of the fixed sleeve; The thickness of the sealing sleeve is much smaller than that of the fixing sleeve; The fixing sleeve and the sealing sleeve are made of the same soft silicone.

[0009] Preferably, the pressure assembly includes a support plate fixedly connected to the outer wall of the bending sleeve; The side of the support plate furthest from the bending sleeve is arc-shaped; The support plate and the bending sleeve are made of the same soft silicone.

[0010] Preferably, the elastic component includes a plurality of through slots formed on the outer wall of the fixed sleeve; The outer wall of the elastic plate is fixedly connected to the inner wall of the through groove; There are six through slots, which are arranged in a circular array.

[0011] Preferably, the support assembly includes a top sleeve ring fixedly connected to the outer wall of the bending sleeve, and the outer wall of the top sleeve ring is provided with a plurality of bending grooves; The bending groove faces the fixed sleeve; There are six top sleeves, which connect two adjacent bending sleeves. There are three bending grooves arranged in a linear array.

[0012] Preferably, the locking component includes a locking groove formed on the outer wall of the sound outlet; The locking groove is arranged in a ring on the outer wall of the sound outlet; The elastic plate extends towards the sound outlet and can be engaged with the inner wall of the locking groove.

[0013] The present invention has the following beneficial effects: (1) When the user inserts the earphone into the ear canal, the inner wall of the ear canal exerts pressure on the support plate in the direction of the fixed sleeve. At this time, the six elastic plates and the bending sleeve will tilt towards the main body. The elastic plates will accumulate elastic potential energy, which will be applied to the inner wall of the fixed sleeve and then transferred to the inner wall of the ear canal to fix the earphone. The six bending sleeves and elastic plates are arranged in a circumferential array and can be bent independently, so as to adapt to ear canals of different sizes and shapes. Through the application of the above components, the problem of the earphone falling off due to normal behavior when the user wears the earphone is effectively prevented, and the adaptability to ear canals of different sizes and shapes is improved.

[0014] (2) This invention utilizes the bending characteristics of the elastic plate of the above-mentioned device. When the elastic plate and the bending sleeve are bent for support, the radial support point of the fixed sleeve is not continuous and circular. At this time, the fixed sleeve between the two bending sleeves will detach from the inner wall of the ear canal due to lack of support, resulting in a gap in the seal and causing a deviation in tone. When the elastic plate and the bending sleeve are bent, the support plate will move closer together, thereby reducing the distance between the two support plates. At this time, the top sleeve ring will bend towards the fixed sleeve under the influence of the bending groove, so that the top sleeve ring can be tightly attached to the fixed sleeve and press the fixed sleeve tightly against the ear canal. Through the application of the above components, it effectively prevents the sealing sleeve from detaching from the inner wall of the ear canal during use, resulting in a small gap in the seal and causing sound leakage.

[0015] (3) The present invention utilizes the feature of the support plate contacting the fixing sleeve in contacting the inner wall of the ear canal. When in use, because the elastic plate material is relatively hard, the elastic plate directly contacts the fixing sleeve, which will continuously exert pressure on the inner wall of the ear canal. By setting the support plate, when the elastic plate deforms, the pressure is first transmitted to the bending sleeve and then to the support plate. By setting the support plate as a larger plane, the pressure generated by the bending sleeve will be evenly distributed to a larger area through the support plate, thereby reducing the pressure per unit area. Through the application of the above components, the problem of excessive pressure squeezing the inner wall of the ear canal and causing discomfort to the user's ear canal is effectively alleviated.

[0016] (4) The present invention utilizes the feature of the elastic plate of the above-mentioned device to be inserted into the slot. When the fixed sleeve is inserted into the outer wall of the sound outlet, the elastic plate will be inserted into the slot. Since the inner diameter of the fixed sleeve is smaller than the outer diameter of the sound outlet, the fixed sleeve will deform when it is installed, so that the inner wall of the fixed sleeve is tightly attached to the outer wall of the sound outlet. The elastic plate is inserted into the slot to further restrict the sliding of the fixed sleeve. Through the application of the above components, the problem of the earplug sleeve coming off the earphone during use is effectively prevented. Attached Figure Description

[0020] 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.

[0021] Example 1, please refer to Figures 1-5 The present invention is a low-interference distributed motherboard sealed in-ear headphone, including a main body 13, a charging terminal 14 fixedly connected to the outer wall of the main body 13, a sound outlet 15 fixedly connected to the outer wall of the main body 13, and further including: Support mechanism 1 is slidably disposed on the outer wall of the sound outlet 15. Support mechanism 1 includes a fixed sleeve 111 slidably connected to the outer wall of the sound outlet 15. Several bent sleeves 121 are fixedly connected to the outer wall of the fixed sleeve 111. The folding mechanism 2 is fixedly installed on the inner wall of the bending sleeve 121. The folding mechanism 2 includes an elastic plate 211 fixedly connected to the inner wall of the bending sleeve 121. Limiting mechanism 3 is installed on the outer wall of the sound outlet 15; The device includes six bending sleeves 121 arranged in a circular array. The fixing sleeve 111 and bending sleeves 121 are made of soft silicone, while the elastic plate 211 is made of hard silicone. The main body 13 is divided into four independent sub-boards according to signal attributes and interconnected by flexible ribbon cables or micro-board connectors. Electromagnetic interference is suppressed by isolating high-frequency harmonics of digital circuits from analog audio signals. The housing is sealed by ultrasonic welding and waterproof rubber rings.

[0022] Supporting mechanism 1 also includes: Sealing assembly 11 is fixedly disposed on the outer wall of fixed sleeve 111; Pressure assembly 12 is installed on the outer wall of bending sleeve 121; The sealing component 11 is used to seal the ear canal, and the pressure component 12 relieves contact pressure.

[0023] The folding mechanism 2 also includes: Elastic component 21 is installed on the outer wall of fixed sleeve 111; Support component 22 is fixedly installed on the outer wall of the bending sleeve 121; Among them, the elastic component 21 restricts the position of the elastic plate 211, and the support component 22 supports the sealing component 11.

[0024] Limiting mechanism 3 includes: The locking component 31 is installed on the outer wall of the sound outlet 15; The locking component 31 restricts the movement of the elastic plate 211.

[0025] Example 2, please refer to Figures 3-8 The present invention is a low-interference distributed motherboard sealed in-ear headphone. Based on Example 1, the sealing component 11 includes a sealing sleeve 112 fixedly connected to the outer wall of the fixing sleeve 111. Among them, the thickness of the sealing sleeve 112 is much smaller than that of the fixing sleeve 111; The fixing sleeve 111 and the sealing sleeve 112 are made of the same soft silicone.

[0026] Pressure assembly 12 includes a support plate 122 fixedly connected to the outer wall of bending sleeve 121; Among them, the side of the support plate 122 away from the bending sleeve 121 is arc-shaped; The support plate 122 and the bending sleeve 121 are made of the same soft silicone. During use, because the elastic plate 211 is made of a relatively hard material, it directly contacts the fixed sleeve 111 and will continuously exert pressure on the inner wall of the ear canal. By setting the support plate 122, when the elastic plate 211 deforms, the pressure is first transmitted to the bending sleeve 121 and then to the support plate 122. By setting the support plate 122 to a larger plane, the pressure generated by the bending sleeve 121 will be evenly distributed to a larger area through the support plate 122, thereby reducing the pressure per unit area.

[0027] The elastic component 21 includes a plurality of through slots 212 formed on the outer wall of the fixed sleeve 111; The outer wall of the elastic plate 211 is fixedly connected to the inner wall of the through groove 212; Six through slots 212 are provided, and the six through slots 212 are arranged in a circular array; When the user inserts the earphone into the ear canal, the sealing sleeve 112 will first contact the inner wall of the ear canal. The sealing sleeve 112 will deform under pressure and continue to be inserted into the earphone. At this time, the sealing sleeve 112 deforms and contacts the support plate 122. The support plate 122 and the bending sleeve 121 are under pressure and begin to deform. At this time, the inner wall of the ear canal exerts pressure on the support plate 122 in the direction of the fixing sleeve 111. Since the elastic plate 211 extends out of the fixing sleeve 111 and the extended part extends into the locking groove 311, the elastic plate 211 will be restricted. When the support plate 122 is subjected to pressure and transmitted to the elastic plate 211, the elastic plate 211 will deform at the position of the through groove 212. At this time, the six elastic plates 211 and the bending sleeve 121 will tilt towards the main body 13. At this time, the elastic plate 211 will accumulate elastic potential energy, which will be applied to the inner wall of the fixing sleeve 111 and then transmitted to the inner wall of the ear canal to fix the earphone. The six bending sleeves 121 and the elastic plates 211 are arranged in a circumferential array and can be bent independently.

[0028] The support component 22 includes a top sleeve 221 fixedly connected to the outer wall of the bending sleeve 121, and the outer wall of the top sleeve 221 is provided with a plurality of bending grooves 222; Among them, the bending groove 222 faces the fixed sleeve 111; There are six top sleeves 221 in total. The top sleeves 221 connect two adjacent bending sleeves 121. There are three bending grooves 222. The three bending grooves 222 are arranged in a linear array. When the elastic plate 211 and the bending sleeve 121 are bent for support, the radial support point of the fixed sleeve 111 is not continuous and circular. At this time, the fixed sleeve 111 between the two bending sleeves 121 will detach from the inner wall of the ear canal due to lack of support, resulting in a gap in the seal and causing a deviation in tone. When the elastic plate 211 and the bending sleeve 121 are bent, the position of the support plate 122 will move closer together, and the distance between the two support plates 122 will decrease. At this time, under the influence of the bending groove 222, the top sleeve ring 221 will bend towards the fixed sleeve 111, so that the top sleeve ring 221 can fit tightly against the fixed sleeve 111 and press the fixed sleeve 111 tightly against the ear canal.

[0029] The locking assembly 31 includes a locking groove 311 formed on the outer wall of the sound outlet 15; Among them, the locking groove 311 is arranged in a ring on the outer wall of the sound outlet 15; The elastic plate 211 extends toward the sound outlet 15, and the elastic plate 211 can be inserted into the inner wall of the locking groove 311.

[0030] One specific application of this embodiment is as follows: When in use, the operator aligns the fixing sleeve 111 with the sound outlet 15 and presses it down so that the fixing sleeve 111 is close to the main body 13 to form a snap-fit ​​fixation. Then, the operator holds the charging end 14, brings the fixing sleeve 111 close to the ear canal, keeps it from falling off, and then releases the charging end 14.

[0031] Once the in-ear headphones are inserted into the ear canal and worn, the continuous changes in head posture and repeated jaw movements during daily activities cause subtle deformations and relative displacements in the soft tissues surrounding the ear canal. This gradually diminishes the friction and clamping force between the headphone housing and the inner wall of the ear canal, disrupting the initial stability of the fit. Especially with slightly larger movements or prolonged wear, the headphones are prone to loosening and falling out of the ear canal, eventually causing them to fall out. When the user inserts the headphones into the ear canal, the sealing sleeve 112 first contacts the inner wall of the ear canal. The sealing sleeve 112 is compressed and deforms. As the headphones continue to be inserted, the sealing sleeve 112 deforms and contacts the support plate 122. The support plate 122 and the bending sleeve 121 are under pressure and begin to deform. At this time, the inner wall of the ear canal exerts pressure on the support plate 122 towards the fixing sleeve 111. Due to elasticity... Plate 211 extends out of fixing sleeve 111 and the extended part extends into the locking groove 311. At this time, elastic plate 211 will be restricted. When the support plate 122 is subjected to pressure and transmitted to elastic plate 211, elastic plate 211 will deform at the through groove 212. At this time, the six elastic plates 211 and bending sleeve 121 will tilt towards the main body 13. At this time, elastic plate 211 will accumulate elastic potential energy, which will be applied to the inner wall of fixing sleeve 111 and then transmitted to the inner wall of ear canal to fix the earphone. The six bending sleeves 121 and elastic plates 211 are arranged in a circumferential array and can be bent independently, so as to adapt to ear canals of different sizes and shapes. Through the application of the above components, the problem of earphones falling off due to normal behavior when the user wears the earphone is effectively prevented, and the adaptability to ear canals of different sizes and shapes is improved.

[0032] Utilizing the bending characteristics of the elastic plate 211 in the aforementioned device, when the elastic plate 211 and the bending sleeve 121 are bent for support, the radial support points of the fixed sleeve 111 are not continuous rings. At this time, the fixed sleeve 111 between the two bending sleeves 121 will detach from the inner wall of the ear canal due to lack of support, resulting in a gap in the seal and causing a deviation in tone. When the elastic plate 211 and the bending sleeve 121 are bent, the position of the support plate 122 will move closer, thereby reducing the distance between the two support plates 122. At this time, under the influence of the bending groove 222, the top sleeve ring 221 will bend towards the fixed sleeve 111, so that the top sleeve ring 221 can fit tightly against the fixed sleeve 111 and press the fixed sleeve 111 tightly against the ear canal. Through the application of the above components, it effectively prevents the sealing sleeve 112 from detaching from the inner wall of the ear canal during use, resulting in a small gap in the seal and causing sound leakage.

[0033] Utilizing the characteristic that the support plate 122 contacts the fixing sleeve 111 in contact with the inner wall of the ear canal, during use, because the elastic plate 211 is made of a relatively hard material, the elastic plate 211 directly contacts the fixing sleeve 111, which will continuously exert pressure on the inner wall of the ear canal. By setting the support plate 122, when the elastic plate 211 deforms, the pressure is first transmitted to the bending sleeve 121, and then to the support plate 122. By setting the support plate 122 to a larger plane, the pressure generated by the bending sleeve 121 will be evenly distributed over a larger area through the support plate 122, thereby reducing the pressure per unit area. Through the application of the above components, the problem of excessive pressure squeezing the inner wall of the ear canal and causing discomfort to the user's ear canal is effectively alleviated.

[0034] Utilizing the feature of the elastic plate 211 engaging with the slot 311, when the fixing sleeve 111 is fitted onto the outer wall of the sound outlet 15, the elastic plate 211 will be engaged within the slot 311. Since the inner diameter of the fixing sleeve 111 is smaller than the outer diameter of the sound outlet 15, the fixing sleeve 111 will deform during installation, causing the inner wall of the fixing sleeve 111 to fit tightly against the outer wall of the sound outlet 15. The engagement of the elastic plate 211 with the slot 311 further restricts the sliding of the fixing sleeve 111. Through the application of the above components, the problem of the ear tips detaching from the headphones during use is effectively prevented.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
