Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a foldable adaptive headband Bluetooth headset. Background Technology

[0002] Bluetooth headphones are widely used in people's daily lives and work, providing users with a convenient audio experience. Whether listening to music and watching videos during leisure and entertainment, or making voice calls and participating in online meetings in an office setting, Bluetooth headphones, with their convenient wireless connectivity, allow users to break free from the constraints of cables and move freely. Current devices typically require the following technologies in practical applications:

[0003] 1. The connecting beam material has good elasticity and strength to adapt to the wearing needs of users with different head shapes and ensure wearing stability;

[0004] 2. The flexible and reliable headphone and connecting beam connection structure allows the headphones to rotate at multiple angles and fit the ear.

[0005] 3. Comfortable and noise-isolating earphone cover material improves sound transmission and reduces external interference.

[0006] Currently, various design approaches are employed to realize the various functions of Bluetooth headphones. Some headphones use connecting beams made of flexible materials, such as plastic or metal.

[0007] However, the above method has a prominent hardware structural problem: the angle between the headphones and the connecting beam is relatively fixed, and the head shape is adapted solely by the elastic deformation of the connecting beam. During use, when encountering users with wider heads, the connecting beam needs to undergo greater deformation. At this time, the headphones are easily pushed and displaced to both ends, resulting in a loose fit with the user's ears, poor sound transmission, increased external noise interference, and the headphones cannot adaptively fit the ears, which greatly affects the wearing comfort and sound transmission effect, and reduces the user experience. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides a foldable adaptive headband Bluetooth headset. This solves the problem of a relatively fixed angle between the headset and the connecting beam, relying solely on the elastic deformation of the connecting beam to adapt to head shape. During use, when encountering users with wider heads, the connecting beam needs to deform significantly, causing the headset to be easily pushed to either end, resulting in a loose fit to the user's ears, poor sound transmission, increased external noise interference, and the headset failing to adaptively fit the ears, greatly affecting wearing comfort and sound transmission, thus reducing the user experience.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A foldable adaptive headband Bluetooth headset includes a support beam, a round rod shaft rotatably connected inside the support beam, a U-shaped headphone bracket sleeved on the outer surface of the round rod shaft, a torsion spring sleeved on the outer surface of the round rod shaft, the torsion spring sleeved on the outer surface of the support beam, an arc-shaped limiting block slidably connected inside the support beam, a pressing and pushing block fixedly connected to the outer surface of the arc-shaped limiting block, a set of triangular slots inside the U-shaped headphone bracket, the arc-shaped limiting block and the set of triangular slots being adapted to each other, and an arc-shaped groove inside the support beam.

[0011] Preferably, the pressing and pushing block is slidably connected inside the arc-shaped groove, and a light rod is fixedly connected inside the U-shaped earphone bracket.

[0012] Preferably, the outer surface of the optical rod is rotatably connected to the headphone body, and the headphone body is rotatably connected inside the U-shaped headphone bracket.

[0013] Preferably, an earphone cover is fitted onto the outer surface of the earphone body, and a spherical slot is provided inside the earphone body.

[0014] Preferably, a helical spring is fixedly connected inside the U-shaped earphone bracket, and a ball is slidably connected inside the U-shaped earphone bracket.

[0015] Preferably, the helical spring is sleeved on the outer surface of the ball, and the ball is inserted into the spherical slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By attaching a torsion spring to the surface of the round rod shaft, elasticity is provided for the two U-shaped headphone brackets, so that the two headphone bodies are always affected by the elasticity and rotate closer to the center position. When the user wears the headphones, the deformation of the support beam adapts to the user's headband, and the two U-shaped headphone brackets that are always close to the center will cause the two headphone bodies to adaptively fit the user's ears, avoiding the fixed placement direction of the headphones, thus preventing the headphones from fitting loosely to the user's ears when the overall opening of the support beam is large.

[0018] Second, the two earphone bodies are supported by a flexible support beam. The earphone bodies are covered by ear tips, which provide a more snug fit for the user's ears. This snug fit ensures that the sound produced by the earphone bodies is transmitted to the user more effectively, reducing sound leakage and external interference. Attached Figure Description

[0025] This application provides a foldable adaptive headband Bluetooth headset, effectively solving the problem of a relatively fixed angle between the headset and the connecting beam. Relying solely on the elastic deformation of the connecting beam to adapt to head shape leads to issues. During use, when encountering users with wider heads, the connecting beam requires significant deformation, causing the headset to be pushed to either end, resulting in a loose fit with the user's ears, poor sound transmission, increased external noise interference, and the headset failing to adaptively fit the ears, greatly affecting wearing comfort and sound transmission, thus reducing the user experience. By attaching a torsion spring to the surface of the round rod shaft, elasticity is provided to the two U-shaped headset supports, ensuring that the two headset bodies are constantly rotated towards the center under the influence of elasticity. When the user wears the headset, the deformation of the support beam adapts to the user's headband, and the two U-shaped headset supports, always moving towards the center, cause the two headset bodies to adaptively fit the user's ears, avoiding a fixed headset placement direction and preventing a loose fit when the support beam is fully open.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that the angle between the headphones and the connecting beam is relatively fixed, relying solely on the elastic deformation of the connecting beam to adapt to the head shape. During use, when encountering users with wider heads, the connecting beam needs to undergo significant deformation. In this case, the headphones are easily pushed to both ends, resulting in a loose fit with the user's ears, poor sound transmission, increased external noise interference, and the headphones failing to adaptively fit the ears, greatly affecting wearing comfort and sound transmission, thus reducing the user experience. The overall concept is as follows: A foldable adaptive headband Bluetooth headphone includes a support beam 11, with a round rod shaft 12 rotatably connected inside the support beam 11. A U-shaped headphone bracket 13 is fitted onto the outer surface of the round rod shaft 12. A torsion spring 14 is fitted onto the outer surface of the round rod shaft 12. The torsion spring 14 is fitted onto the outer surface of the support beam 11. An arc-shaped limiting block 15 is slidably connected inside the support beam 11. A pressing push block 16 is fixedly connected to the outer surface of the arc-shaped limiting block 15. A set of triangular slots 17 are formed inside the U-shaped headphone bracket 13. The arc-shaped limiting block 15 and the set of triangular slots 17 are adapted to each other. An arc-shaped groove 18 is formed inside the support beam 11. The pressing push block 16 is slidably connected inside the arc-shaped groove 18. A smooth rod 19 is fixedly connected inside the U-shaped headphone bracket 13. The headphone body 21 is rotatably connected to the outer surface of the smooth rod 19. Inside the support beam 11, it is rotatably connected to... The round rod pivot 12 provides rotational space for the placement of the U-shaped headphone brackets 13. A torsion spring 14 is fitted onto the surface of the round rod pivot 12, providing elasticity to the two U-shaped headphone brackets 13. This ensures that the two headphone bodies 21 are always influenced by the elasticity and rotate towards the center. When the user wears the headphones, the deformation of the support beam 11 adapts to the user's headband, and the two U-shaped headphone brackets 13, always moving towards the center, will cause the two headphone bodies 21 to adaptively fit the user's ears, avoiding a fixed headphone placement direction. This prevents the headphones from loosely fitting the user's ears when the support beam 11 is fully open. During extended wear, the user can press and push the headphones with both hands. The surface of the moving block 16 pushes the arc-shaped limiting insert 15 downward to slide. The arc-shaped limiting insert 15 is attached to the inner wall of the support beam 11 through the adhesive rubber pad on its surface, thereby ensuring its reliable placement. (Alternatively, a spring can be set at the upper end of the arc-shaped limiting insert 15 so that the arc-shaped limiting insert 15 is always sliding downward due to the elastic force. However, this method requires the user to push the arc-shaped limiting insert 15 upward to slide it when wearing it.) The arc-shaped limiting insert 15 slides downward and engages in the triangular slot 17, thereby limiting the position of the U-shaped headphone bracket 13. This avoids the influence of the elastic force of the torsion spring 14, which would cause the headphone body 21 to exert greater pressure on the ear and affect the long-term wearing experience.

[0028] The headphone body 21 is rotatably connected inside the U-shaped headphone bracket 13. The outer surface of the headphone body 21 is fitted with a headphone cover 22. The support beam 11 is made of spring steel or thermoplastic elastomer (TPE) material, which has good elasticity and can be pulled open when worn, and actively deform and return to its original shape when the tension is removed, thereby conforming to the size of the user's headband and ensuring the stability of the over-ear headphones. (Thermoplastic elastomer material is cheaper than spring steel and can be selected according to actual needs.) The support beam 11 provides support for the two headphone bodies 21. The headphone covers 22 fitted on the surfaces of the two headphone bodies 21 provide a more snug fit for the user's ears. The snug fit ensures that the sound produced by the headphone body 21 is transmitted to the user more effectively, reducing sound leakage and external interference.

[0029] The earphone body 21 has a spherical slot 23 inside. A coil spring 24 is fixedly connected inside the U-shaped earphone bracket 13. A ball bearing 25 is slidably connected inside the U-shaped earphone bracket 13. The coil spring 24 is sleeved on the outer surface of the ball bearing 25, and the ball bearing 25 is inserted into the spherical slot 23. Inside the U-shaped earphone bracket 13, it is rotatably connected to the earphone body 21 through a rod 19. The rotatably connected earphone body 21 can be folded for storage when the earphone is not in use, thereby reducing the overall height of the earphone and improving the convenience of storage. Inside the U-shaped headphone bracket 13, a ball bearing 25 is installed on the surface of the coil spring 24, and a slot slightly smaller than the diameter of the ball bearing 25 is opened in the U-shaped headphone bracket 13. This ensures that the ball bearing 25 can extend and engage in the ball slot 23 without slipping, thereby limiting the headphone body 21 and ensuring the stability of the headphone body 21 in the extended state. When it is necessary to flip the headphone body 21 for storage, push the headphone body 21 to rotate, and the surface of the headphone body 21 will contact the arc surface of the ball bearing 25 and lift it upward, thereby achieving the engaging effect.

[0030] To address the problems existing in the prior art, this utility model provides a foldable adaptive headband Bluetooth headset. By attaching a torsion spring 14 to the surface of the round rod pivot 12, elasticity is provided for the two U-shaped headphone brackets 13, causing the two headphone bodies 21 to rotate closer to the center position under the influence of the elasticity. When the user wears the headset, the deformation of the support beam 11 adapts to the user's headband, and the two U-shaped headphone brackets 13, which are always closer to the center, will cause the two headphone bodies 21 to adaptively fit the user's ears, avoiding the fixed placement direction of the headset and thus preventing the headset from being loosely fitted to the user's ears when the support beam 11 is opened to a large extent.

[0031] Support beam 11: Made of spring steel or thermoplastic elastomer (TPE), it can be stretched and opened when worn due to its good elasticity, and actively reset after the tension is removed, conforming to the size of the user's headband, providing support for the two headphone bodies 21, and ensuring that the headphones are worn stably.

[0032] Round rod pivot 12: Provides rotation space for U-shaped headphone bracket 13. Cooperating with the sleeved torsion spring 14, it causes the U-shaped headphone bracket 13 to rotate the headphone body 21 toward the center position, so that the headphone can adaptively fit the user's ear when worn.

[0033] U-shaped headphone stand 13: Under the elastic force of torsion spring 14, the headphone body 21 adaptively conforms to the ear. Its internal triangular slot 17 cooperates with the arc-shaped limiting block 15 to limit its position. In addition, the headphone body 21 is rotatably connected to the internally fixed light rod 19, realizing the folding and storage of the headphone.

[0034] Torsion spring 14: Provides elasticity to the two U-shaped headphone brackets 13, causing the two headphone bodies 21 to always be affected by the elasticity and rotate closer to the center position, so as to achieve the effect of the headphones adapting to fit the user's ears.

[0035] Arc-shaped limiting insert 15: It adheres to the inner wall of the support beam 11 with the help of an adhesive rubber pad on its surface to ensure reliable positioning. It can slide downward and snap into the triangular slot 17 inside the U-shaped headphone bracket 13 to limit the position of the U-shaped headphone bracket 13 and prevent the torsion spring 14 from causing the headphone body 21 to exert excessive pressure on the ear.

[0036] Press and push block 16: The user pushes the arc-shaped limiting plug 15 to slide by pressing its surface with both hands. The operation is convenient and together with the arc-shaped limiting plug 15, the position of the U-shaped headphone bracket 13 can be adjusted.

[0037] Triangular slot 17: Adapts to arc-shaped limiting plug 15, and the two work together to limit the position of the U-shaped headphone bracket 13.

[0038] Arc-shaped groove 18: The pressing push block 16 slides in it, providing a sliding track for the pressing push block 16 and ensuring its sliding stability and accuracy.

[0039] Bare rod 19: Its outer surface is rotatably connected to the headphone body 21, so that the headphone body 21 can be folded and stored when the headphones are not in use, reducing the overall height of the headphones and improving storage convenience.

[0040] The earphone body 21 is rotatably connected to the U-shaped earphone bracket 13 via the light rod 19, allowing it to be folded for storage. Inside the earphone body 21 is a speaker unit, which is the core component for generating sound. The speaker unit includes key components such as a diaphragm and a voice coil. When the audio electrical signal is transmitted to the earphone body 21 through the wire and reaches the voice coil of the speaker, the voice coil is in a magnetic field. According to the principle of electromagnetic induction, the changing current will cause the voice coil to vibrate. The audio electrical signal is transmitted through components such as mobile phones and computers and technologies such as Bluetooth and Wi-Fi installed in the earphone body 21. In the actual production of the earphone, protective covers need to be installed on the surface of components such as the torsion spring 14 and the round rod shaft 12 at the outer end to avoid direct contact between the components and the user's skin, which may cause discomfort.

[0041] Earphone cover 22: Provides a more snug fit for the user's ears, reduces sound leakage and external interference, and ensures that the sound produced by the earphone body 21 is delivered to the user more effectively.

[0042] Spherical slot 23: It engages with the ball 25 extending from the U-shaped headphone bracket 13 to limit the headphone body 21 and ensure its stability when extended.

[0043] Helical spring 24: Provides elasticity to ball 25, allowing it to extend and engage in ball slot 23, ensuring the limiting effect of the headphone body 21.

[0044] Ball 25: Under the elastic force of the coil spring 24, it extends and engages with the spherical slot 23 of the earphone body 21, limiting the earphone body 21. When the earphone body 21 is rotated and retracted, it is pushed upward and disengaged from the engagement.

[0045] Working principle:

[0046] The first step involves using a support beam 11 made of spring steel or thermoplastic elastomer (TPE), which has good elasticity and can be stretched open when worn and actively deformed and returned to its original shape when the tension is removed. This conforms to the size of the user's headband and ensures the stability of the headphones. (Thermoplastic elastomer is less expensive than spring steel and can be chosen according to actual needs.) The support beam 11 provides support for the two earphone bodies 21. The earphone bodies 21, through the earphone covers 22 attached to their surfaces, provide a more snug fit for the user's ears. This snug fit ensures that the sound produced by the earphone bodies 21 is transmitted to the user more effectively, reducing sound leakage and external interference.

[0047] The second step involves a rotating shaft 12, rotatably connected inside the support beam 11, providing rotational space for the placement of the U-shaped headphone brackets 13. A torsion spring 14 is fitted onto the surface of the shaft 12, providing elasticity to the two U-shaped headphone brackets 13. This elasticity causes the two headphone bodies 21 to rotate towards the center position. When the user wears the headphones, the deformation of the support beam 11 adapts to the user's headband, and the two U-shaped headphone brackets 13, always moving towards the center, cause the two headphone bodies 21 to adaptively conform to the user's ears, preventing a fixed headphone placement orientation. Therefore, when the support beam 11 is fully open, the earphone may not fit snugly against the user's ear. To prevent this, when the user wears the earphone for an extended period, they can press down on the surface of the push block 16 with both hands to slide the arc-shaped limiting insert 15 downwards. The arc-shaped limiting insert 15 adheres to the inner wall of the support beam 11 via an adhesive rubber pad, ensuring its reliable placement. (Alternatively, a spring can be installed at the upper end of the arc-shaped limiting insert 15, causing it to slide downwards under the influence of elasticity. However, this method requires the user to first push the arc-shaped limiting insert 15 upwards during wear.) 5. Sliding) The curved limiting insert 15 slides downward and engages with the triangular slot 17, thereby limiting the position of the U-shaped headphone bracket 13. This avoids the influence of the torsion spring 14, which could cause the headphone body 21 to exert excessive pressure on the ear, affecting the long-term wearing experience. Inside the U-shaped headphone bracket 13, the light rod 19 is rotatably connected to the headphone body 21. The rotatably connected headphone body 21 can be folded for storage when the headphones are not in use, thereby reducing the overall height of the headphones and improving the convenience of storage. The U-shaped headphone bracket 13 has a ball bearing 25 installed on the surface of the coil spring 24, and a slot slightly smaller than the diameter of the ball bearing 25 is opened in the U-shaped headphone bracket 13. This ensures that the ball bearing 25 can extend and engage in the ball slot 23 without slipping, thereby limiting the headphone body 21 and ensuring the stability of the headphone body 21 in the extended state. When it is necessary to flip the headphone body 21 for storage, the headphone body 21 is rotated, and the surface of the headphone body 21 will contact the arc surface of the ball bearing 25 and lift it upward, thereby achieving the engaging effect.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
