Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a wireless Bluetooth headset with adaptive ear tips. Background Technology

[0002] Wireless Bluetooth headsets are hands-free headset products that utilize Bluetooth technology. They are widely used in mobile communications, music playback, and other fields. Wireless Bluetooth headsets are earphone devices that use Bluetooth technology for wireless communication, allowing users to connect and use them with devices such as mobile phones and computers without a physical connection. Through a built-in Bluetooth module, the headset can automatically pair with Bluetooth-enabled devices to achieve wireless data transmission. This technology supports point-to-point and point-to-multipoint communication methods, making it ideal for listening to music or making phone calls while on the go.

[0003] In existing technologies, users encounter challenges when attempting to insert earbuds into their ear canals, especially those with smaller ear canals. Standard earbuds often fail to fit properly, resulting in unnatural deformation when forcibly inserted. This deformation typically manifests as the outer surface of the earbud bending inward to better accommodate the narrow space. However, this adaptation is often unsatisfactory. First, because the outer surface of the earbud bends inward, it can no longer form an effective seal with the user's ear canal wall. This misfit means that external noise can more easily enter the ear canal, reducing the noise isolation the earbuds should provide. This not only affects the user's experience when listening to music or watching videos but also interferes with call clarity in noisy environments. Second, this deformation of the earbud also generates a reaction force that continuously applies pressure to the user's ear canal. Prolonged exposure to such pressure can cause earache and soreness, obviously affecting the comfort of wearing headphones. For users who need to use headphones for extended periods, this discomfort can become unbearable. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wireless Bluetooth headset with adaptive ear tips.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wireless Bluetooth earphone with adaptive ear tips, comprising an earphone body, a mounting post fixed to one side of the earphone body, a hollow rubber post nested at one end of the mounting post, an ear tip arc plate fixed to one end of the hollow rubber post, an installation ring groove formed on the inner circumferential surface of the hollow rubber post, a reserved truncated pyramidal groove formed on the edge of the circumferential surface of the ear tip arc plate, an anti-crack ring fixed to the inner wall of the bottom end of the reserved truncated pyramidal groove, and the circumferential surface of the anti-crack ring fixed to the inner circumferential surface of the ear tip arc plate.

[0006] Preferably, the surface of the earplug arc plate is provided with a cross-shaped groove, and an inner retaining ring is fixed to the circumferential surface of the inner wall of the earplug arc plate. In the prior art, when users try to insert earplugs into their ear canals, they usually need to adjust the position of the earplugs by rotating the earphones to find the most suitable wearing point for their ear canal shape. Since everyone's ear canal shape and size are different, this process of finding the right position becomes particularly important. However, the challenge in this process is that the pressure on the earplugs is often unevenly distributed in the ear canal. The design of earplugs is usually circular or other symmetrical shapes, which means that their contact surface in the ear canal is uniform. However, when the earplugs are subjected to pressure from different directions, these pressure differences cause the earplugs to be squeezed out of the area with less pressure. This situation is particularly obvious when users exercise or perform other head movements, because head movement increases the relative movement between the earplugs and the ear canal, thereby increasing the risk of the earplugs falling out. To address this problem, this utility model solves the problem by providing a cross-shaped groove, which allows the earplugs to be inserted into the ear canal without being squeezed out. When inserted into the ear canal, a carefully designed structure—the cross-shaped groove—plays a crucial role. This groove divides the earbud's curved plate into four independent parts, each with greater autonomy, capable of deforming independently according to varying pressure. This design allows the earbud to more flexibly adapt to different shapes and sizes within the ear canal, thereby improving wearing comfort and sealing. Simultaneously, to ensure the overall stability and durability of the earbud, the design of the inline retaining ring is also essential. By applying uniform restraint to each part of the earbud's curved plate, it maintains the autonomy of each part while also being influenced by the overall structure. This uniform influence prevents fragility and easy dislodgement issues caused by the cross-shaped groove. Through this design, headphone manufacturers can provide greater adaptability and comfort without sacrificing earbud stability. Users not only experience better noise isolation and sound quality but also enjoy a more secure fit during exercise or other activities, ultimately extending the device's lifespan.

[0007] Preferably, a main reinforcing rib is fixed to the inner wall of the mounting ring groove, and a secondary reinforcing rib is fixed to the inner wall of the mounting ring groove. In the prior art, when a user installs an earbud onto an earphone, it is usually necessary to pull the earbud to deform the hollow rubber column so that it can be tightly nested with the mounting post. This step is crucial to ensuring that the earbud is firmly attached to the earphone, but it also brings certain challenges. Because this deformation process occurs frequently in daily use, especially when the user needs to clean or replace the earbud, the degree of deformation of the hollow rubber column will be aggravated. Long-term repeated deformation and recovery This can lead to material fatigue in the hollow rubber column, increasing the risk of tearing. Once the hollow rubber column tears, it not only affects the earplug's fixation but also damages the entire product, as the earplug can no longer be securely installed on the headphones. Furthermore, the torn hollow rubber column leaves fragments inside the ear canal, which can cause injury or discomfort to the user's ears. To address these issues, this invention employs a main reinforcing rib, which strengthens the hollow rubber column as a whole and its various parts through main and secondary reinforcing ribs, preventing tearing and thus extending the lifespan of the device.

[0008] Preferably, the inner wall of the earbud arc is provided with a thin ear groove, which reduces the thickness of the earbud arc and improves the user experience.

[0009] Preferably, the inner wall of the hollow rubber column is provided with an installation auxiliary groove, which makes it easier for users to install earplugs and improves the user experience.

[0010] Preferably, the other top side of the earphone body has an anti-slip groove, which makes it easier for users to install earplugs and improves the user experience.

[0011] Preferably, the earphone body has double-sided pinch grooves on both sides, which makes it easier for users to install earplugs and improves the user experience.

[0012] Beneficial effects:

[0013] 1. In existing technologies, users encounter challenges when attempting to insert earbuds into their ear canals, especially those with small ear canals. Standard earbuds may not fit perfectly. In such cases, when earbuds are forcibly inserted, they undergo unnatural deformation. This deformation typically manifests as the outer surface of the earbud bending inward to better adapt to the narrow space. However, this adaptive change is often unsatisfactory. First, because the outer surface of the earbud bends inward, it can no longer form an effective seal with the user's ear canal wall. This misfit means that external noise can more easily enter the ear canal, reducing the noise isolation the earbuds should provide. This not only affects the user's experience when listening to music or watching videos but also interferes with call clarity in noisy environments. Second, this deformation of the earbud also generates a reaction force that continuously applies pressure to the user's ear canal. Prolonged exposure to such pressure can cause earache and soreness, obviously affecting the comfort of wearing headphones. For users who need to use headphones for extended periods, this discomfort can become... To address this unbearable problem, this invention employs a pre-designed truncated pyramidal groove. This groove plays a crucial role when a user attempts to insert the earphone's curved piece into their ear canal. The groove design considers the deformation of the earphone within the ear canal, especially in smaller ear canals. Because of the pre-designed deformation space, the earphone's curved piece can adjust from a larger to a smaller diameter, rather than being forced to fit the narrow ear canal. This design significantly reduces the degree of inward bending of the earphone, providing a natural transition area that allows the earphone to more smoothly adapt to the shape of the ear canal. This not only ensures an effective seal between the earphone and the ear canal wall, improving sound insulation and audio quality, but also greatly reduces the reaction force caused by deformation. The reduced reaction force also alleviates the pressure felt by the user when wearing the earphone, meaning that even with prolonged wear, the user's ears are less likely to experience significant swelling or soreness, thus improving the user experience.

[0014] 2. In existing technologies, when users attempt to insert earbuds into their ear canals, they typically need to rotate the earbuds to adjust their position and find the most suitable wearing point for their ear canal shape. Since everyone's ear canal shape and size are different, this process of finding the right position becomes particularly important. However, the challenge lies in the fact that the pressure on the earbuds is often unevenly distributed within the ear canal. Earbuds are usually designed to be circular or other symmetrical shapes, meaning their contact surface within the ear canal is uniform. However, when the earbuds are subjected to pressure from different directions, these pressure differences cause the earbuds to be squeezed out of areas of lower pressure. This is especially noticeable when users exercise or engage in other head movements, as head movement increases the relative movement between the earbuds and the ear canal, thus increasing the risk of the earbuds falling out. To address this problem, this invention solves it by creating a cross-shaped groove, resulting in a carefully designed structure—the cross-shaped groove—that allows the earbuds to be inserted into the ear canal. The groove design plays a crucial role, dividing the in-ear tip into four independent parts, each with greater autonomy and the ability to deform independently according to different pressures. This design allows the earbud to more flexibly adapt to different shapes and sizes within the ear canal, thereby improving wearing comfort and sealing. Meanwhile, the inline retaining ring design is also essential to ensure the overall stability and durability of the earbud. By applying uniform constraints to each part of the in-ear tip, it maintains the autonomy of each part while also being influenced by the overall structure. This uniform influence prevents fragility and easy detachment issues caused by the cross-shaped groove. Through this design, headphone manufacturers can provide greater adaptability and comfort without sacrificing earbud stability. Users not only experience better noise isolation and sound quality when wearing them, but also enjoy a more secure fit during exercise or other activities, thus extending the device's lifespan.

[0015] 3. In existing technology, when a user installs an earbud onto headphones, the hollow rubber column is usually deformed by pulling the earbud so that it can be tightly nested with the mounting post. This step is crucial to ensuring that the earbud is securely attached to the headphones, but it also presents certain challenges. Because this deformation process occurs frequently in daily use, especially when the user needs to clean or replace the earbud, the deformation of the hollow rubber column will be aggravated. Long-term repeated deformation and recovery will lead to material fatigue of the hollow rubber column, thereby increasing the risk of tearing. Once the hollow rubber column tears, it will not only affect the fixation of the earbud, but also lead to the damage of the entire product, because the earbud can no longer be securely installed on the headphones. In addition, the torn hollow rubber column will leave fragments in the ear canal, which will cause injury or discomfort to the user's ears. To address these issues, this utility model adopts a main reinforcing rib to solve the problem. It achieves the reinforcement of the hollow rubber column as a whole and its various parts through the main reinforcing rib and the secondary reinforcing rib, preventing the hollow rubber column from tearing and thus improving the service life of the device.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4 A wireless Bluetooth headset with adaptive ear tips includes a headset body 1. A mounting post 101 is fixed to one side of the headset body 1. A hollow rubber post 103 is nested at one end of the mounting post 101. An ear tip arc plate 102 is fixed to one end of the hollow rubber post 103. An installation ring groove 104 is opened on the circumferential surface of the inner wall of the hollow rubber post 103. A reserved truncated pyramid groove 2 is opened on the edge of the circumferential surface of the ear tip arc plate 102. An anti-crack ring 203 is fixed on the inner wall of the bottom end of the reserved truncated pyramid groove 2. The circumferential surface of the anti-crack ring 203 is fixed to the circumferential surface of the inner wall of the ear tip arc plate 102. The surface of the in-ear tip arc plate 102 has a cross-shaped groove 201, and an inner retaining ring 202 is fixed to the inner circumferential surface of the in-ear tip arc plate 102. When users try to insert the earbuds into their ear canals, they usually need to adjust the position of the earbuds by rotating the earphones to find the most suitable wearing point for their ear canal shape. Since everyone's ear canal shape and size are different, this process of finding the right position becomes particularly important. However, the challenge in this process is that the pressure on the earbuds is often unevenly distributed in the ear canal. The design of earbuds is usually circular or other symmetrical shapes, which means that their contact surface in the ear canal is uniform. However, when the earbuds are subjected to pressure from different directions, these pressure differences cause the earbuds to be squeezed out of the areas with less pressure. This situation is particularly noticeable when users exercise or perform other head movements, because head movement increases the relative movement between the earbuds and the ear canal, thereby increasing the risk of the earbuds falling out. The cross-shaped groove 201 is used to solve this problem, achieving a carefully designed fit when the user inserts the earbuds into the ear canal. The structure—the cross-cut groove 201 plays a crucial role. This groove divides the in-ear tip arc 102 into four independent parts, each with greater autonomy, capable of independent deformation according to different pressures. This design allows the earbud to more flexibly adapt to different shapes and sizes within the ear canal, thereby improving wearing comfort and sealing. Simultaneously, the design of the inline limiting ring 202 is also essential to ensure the overall stability and durability of the earbud. By applying uniform restraint to each part of the in-ear tip arc 102, it maintains the autonomy of each part while also being influenced by the overall structure. This uniform influence prevents fragility and easy detachment issues caused by the cross-cut groove 201. Through this design, headphone manufacturers can provide greater adaptability and comfort without sacrificing earbud stability. Users not only experience better noise isolation and sound quality when wearing the earbud, but also enjoy a more secure fit during exercise or other activities, thus extending the device's lifespan.

[0026] The inner wall of the mounting ring groove 104 is fixed with a main reinforcing rib 206 and a secondary reinforcing rib 207. When the user installs the earbud onto the headphones, the hollow rubber post 103 is usually deformed by pulling the earbud so that it can be tightly nested with the mounting post 101. This step is crucial to ensuring that the earbud is firmly attached to the headphones, but it also presents certain challenges. Because this deformation process occurs frequently in daily use, especially when the user needs to clean or replace the earbud, the degree of deformation of the hollow rubber post 103 will be aggravated. Long-term repeated deformation and recovery will lead to the hollow rubber post 103 being hollow. Material fatigue in the hollow rubber column 103 increases the risk of tearing. Once the hollow rubber column 103 tears, it not only affects the earbud's fixation but also damages the entire product, as the earbud can no longer be securely installed on the headphones. Furthermore, the torn hollow rubber column 103 leaves fragments in the ear canal, which can cause injury or discomfort to the user's ears. This is addressed by using a main reinforcing rib 206, which, along with secondary reinforcing ribs 206 and 207, strengthens the hollow rubber column 103 as a whole and its individual parts, preventing tearing and extending the device's lifespan. A thin ear groove 204 is formed on the inner wall of the earbud arc 102, reducing its thickness and improving the user experience. An installation auxiliary groove 205 is formed on the inner wall of the hollow rubber column 103, facilitating earbud installation and improving the user experience. An anti-slip back groove 3 is formed on the top of the other side of the headphone body 1, further facilitating earbud installation and improving the user experience. Both sides of the earphone body 1 have double pinch grooves 301, which makes it easier for users to install ear tips and improves the user experience.

[0027] The working principle of this utility model is as follows: When a user attempts to insert the curved piece of an in-ear headphone into their ear canal, the reserved truncated pyramid groove 2 plays a crucial role. The design of this truncated pyramid groove takes into account the deformation problem encountered by the earplug in the ear canal. Especially when the ear canal size is small, due to the reserved deformation space, the curved piece 102 of the in-ear headphone can be adjusted from the larger to the smaller diameter using this reserved space, rather than forcibly adapting to the narrow ear canal. This design significantly reduces the degree of inward bending of the earplug because it provides a natural transition area, allowing the earplug to adapt to the shape of the ear canal more smoothly. This not only ensures that an effective seal can be formed between the earplug and the ear canal wall, thereby improving the sound insulation effect and sound quality experience, but also greatly reduces the reaction force generated by deformation. Due to the reduction of the reaction force, the pressure felt by the user when wearing the headphones is also reduced accordingly. This means that even if worn for a long time, the user's ears are less likely to experience obvious swelling or soreness.
