Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear clip-on headphone structure. Background Technology

[0002] As people's demands for headphones increase, prolonged use of in-ear headphones can cause ear canal blockage and discomfort. Therefore, clip-on headphones have emerged. Clip-on headphones can be held in place on the user's ear without going inside, improving wearing comfort.

[0003] However, the existing ear clip-on wireless earphones are not ergonomically designed, and prolonged wear can cause ear pain for users. Utility Model Content

[0004] This invention provides an ear clip-on headphone structure that improves wearing comfort by incorporating a flexible connecting bridge.

[0005] This utility model embodiment provides an ear clip-on headphone structure, including:

[0006] The first housing contains a sound-generating module and has multiple sound outlets.

[0007] The second housing is spaced apart from the first housing and forms a clamping space between the first housing and the second housing. The second housing contains a battery for providing power to the sound-generating module.

[0008] A connecting bridge includes a first end and a second end. The first end is fixedly connected to a first housing, and the second end is fixedly connected to a second housing. The connecting bridge is elastic and has an arc-shaped structure.

[0009] The connecting bridge includes an outer wall and an inner core. The outer wall wraps around the outside of the inner core, and the hardness of the outer wall is between 80 Shore A and 90 Shore A.

[0010] By providing a first housing, a space is created for the sound-generating module, allowing it to be housed within the housing and preventing movement. A sound outlet on the first housing allows sound to be transmitted to the outside, improving sound quality. A second housing facilitates battery placement, providing power to the sound-generating device. A connecting bridge connects the first and second housings, creating a clamping space between them for comfortable wear. A flexible connecting bridge provides a secure grip when the earcup headphones are worn, enhancing stability. The connecting bridge's structure, including an inner core and an outer wall, provides support through the inner core and enhances comfort through the outer wall. A softer outer wall, with a hardness between 80 and 90 Shore A, further improves wearing comfort.

[0011] In one possible implementation, the connecting bridge has a C-shaped structure.

[0012] By designing the connecting bridge in a C-shape, a gap is created between the connecting bridge and the user's ear when the ear clip-on headphone structure is worn on the user's ear, preventing it from hitting the auricle and thus avoiding pain caused by the ear clip-on headphone structure clamping the auricle cartilage.

[0013] In one possible implementation, the length of the connecting bridge is greater than 2 / 3 of the overall length of the ear clip-on headphone structure in the extending direction of the connecting bridge.

[0014] By setting the length of the connecting bridge to be greater than 2 / 3 of the overall length of the ear clip-on headphone structure in the extension direction of the connecting bridge, the proportion of the connecting bridge can be increased. Since the connecting bridge is an elastic structure, this increases the proportion of elastic structure, and the area of ​​deformation of the connecting bridge is larger, so it can adapt to a greater degree of deformation, and thus can adapt to more users with different ear shapes, thereby improving adaptability.

[0015] In one possible implementation, one end of the inner core is fixedly connected to the first housing, and the other end is fixedly connected to the second housing;

[0016] One end of the outer wall is fixedly connected to the first housing, and the other end is fixedly connected to the second housing;

[0017] The inner core is a memory metal wire, which is elastic.

[0018] By fixing the two ends of the inner core to the first and second housings respectively, and connecting the two ends of the outer wall to the first and second housings respectively, the connection stability between the connecting bridge and the first and second housings can be increased, thereby improving the structural strength of the ear clip-on headphone structure and extending its service life. The outer wall on the outside of the inner core provides protection and makes it easier to shape and choose skin-friendly materials, thus enhancing wearing comfort.

[0019] It should be noted that, in the embodiments of this utility model, "memory metal wire" refers to an elastic metal component with "memory" shape function, which can deform under external force and can completely restore the original pre-constructed shape after the external force is removed.

[0020] In one possible implementation, the shape memory wire is a titanium wire or a titanium alloy wire.

[0021] This design enhances the comfort of clip-on earphones. The memory titanium wire, with its excellent elasticity and flexibility, adjusts to the wearer's ear shape for a more comfortable fit. Its high strength and fatigue resistance allow it to withstand repeated bending and stretching, preventing breakage and extending the earphone's lifespan. The low density of the memory titanium wire contributes to the earphone's lighter weight, reducing strain during extended wear. The memory titanium wire returns to its pre-set shape at specific temperatures, meaning the earphones maintain a compact shape when not in use, facilitating storage and portability. Titanium's excellent corrosion resistance ensures stability in humid environments, preventing rust and making it suitable for long-term use. The memory titanium wire remains stable across a wide temperature range, ensuring the earphone's performance is unaffected by changes in ambient temperature.

[0022] In one possible implementation, the diameter of the shape memory wire is between 0.4 mm and 0.6 mm.

[0023] In one possible implementation, the diameter of the shape memory wire is 0.5 mm.

[0024] It's worth noting that the 0.4mm-0.6mm memory titanium wire is thinner, making it suitable for headphone components requiring delicate and complex designs, such as ear hooks and headphone frames, enabling more intricate structures. The thinner titanium wire further reduces the weight of the headphones, making them lighter and less burdensome to wear, enhancing user comfort. The 0.4mm-0.6mm memory titanium wire has good flexibility, better conforming to the shape of the ear, improving wearing stability and comfort. Despite its smaller diameter, the memory titanium wire maintains high strength and fatigue resistance, able to withstand repeated bending and stretching without breaking, extending the headphone's lifespan. The thinner diameter memory titanium wire effectively returns to its preset shape when temperature changes, allowing the headphones to maintain a compact form when not in use, facilitating storage and portability. Titanium itself has excellent corrosion resistance; the 0.4mm-0.6mm memory titanium wire remains stable in humid environments, is not prone to rust, and is suitable for long-term use. The thinner titanium wire performs well in thermal conductivity, responding more quickly to temperature changes and achieving rapid shape memory.

[0025] In one possible implementation, the outer wall is a soft rubber wall.

[0026] By using a soft rubber outer wall, the earphones better conform to the shape of the ear due to the softness and elasticity of the material, reducing pressure and improving comfort. Soft rubber typically has a high coefficient of friction, effectively preventing the earphones from slipping off during wear, providing a more stable wearing experience, especially suitable for sports. Soft rubber also has good abrasion and tear resistance, withstanding the pulling and bending of daily use, extending the lifespan of the earphones. Furthermore, soft rubber is generally lightweight, not adding to the overall weight of the earphones, reducing the burden of wearing them, and making them suitable for extended use.

[0027] In one possible implementation, the soft rubber wall is a silicone wall or a rubber wall.

[0028] By using silicone or rubber as the soft inner wall, the wearing comfort of clip-on earphones can be improved, as silicone is a biocompatible material that does not irritate the skin. Silicone has excellent UV and oxidation resistance, is not prone to aging, and has a long service life. Silicone is very soft, making it suitable for applications requiring high flexibility and comfort. The smooth surface of silicone makes it easy to clean and maintain. Rubber has excellent elasticity and flexibility, capable of withstanding significant deformation without damage, making it suitable for shock absorption and sealing materials.

[0029] In one possible implementation, the first housing and the second housing are movably configured, and the first housing is switchable between a first position and a second position relative to the second housing; wherein...

[0030] When the first housing is in the first position, the included angle between the first end and the second end of the connecting bridge is 3.5°.

[0031] When the first housing is in the second position, the included angle between the first end and the second end of the connecting bridge is 10°.

[0032] When the first housing moves relative to the second housing, it passes through at least the first position and the second position.

[0033] This design allows the angle between the first and second ends of the connecting bridge to be changed. In other words, the clamping space between the first and second shells can be increased or decreased, thus making it suitable for people with more different ear sizes.

[0034] In one possible implementation, the side of the second housing facing the first housing is an inwardly concave arc-shaped surface.

[0035] By setting the side of the second shell facing the first shell to be an inwardly concave arc surface, since the auricle of the ear is concave, this allows the second shell to fit more closely to the back of the auricle of the ear, better conforming to the natural shape of the ear, providing a more comfortable wearing experience, and reducing discomfort caused by wearing for a long time.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0058] The ear clip-on headphone structure of this utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0059] like Figure 1As shown, this embodiment of the present invention provides an ear-clip earphone structure 100, which may include a first housing 111, a second housing 112, and a connecting bridge 120. The first housing 111 houses a sound-generating module and has multiple sound outlet holes 113. The second housing 112 is spaced apart from the first housing 111, forming a clamping space between them. A battery is housed within the second housing 112 to provide power to the sound-generating module. The connecting bridge 120 includes a first end 121 and a second end 122. The first end 121 is fixedly connected to the first housing 111, and the second end 122 is fixedly connected to the second housing 112. The connecting bridge 120 is elastic and has an arc-shaped structure.

[0060] like Figure 2 As shown, the connecting bridge 120 includes an outer wall 124 and an inner core 123. The outer wall 124 wraps around the outer side of the inner core 123, and the hardness of the outer wall 124 is between 80 Shore A and 90 Shore A.

[0061] By providing a first housing 111, a space is provided for the sound-generating module to be housed within it, preventing it from shifting. A sound outlet 113 on the first housing 111 allows sound to be transmitted to the outside, enabling the user to hear the sound and improving the sound effect. A second housing 112 facilitates the installation of a battery, providing power to the sound-generating device. A connecting bridge 120 connects the first housing 111 and the second housing 112, creating a clamping space between them for easy wearing.

[0062] By configuring the connecting bridge 120 with a flexible structure, a good clamping force can be formed when the ear clip-on headphone structure 100 is worn on the user's ear 200, thereby improving the wearing stability of the ear clip-on headphone structure 100. By configuring the connecting bridge 120 with a structure including an inner core 123 and an outer wall 124, the inner core 123 can provide a supporting force, while the outer wall 124 can enhance comfort. In particular, by making the hardness of the outer wall 124 of the connecting bridge 120 between 80 Shore A and 90 Shore A, the outer wall 124 can be made relatively soft, thereby improving wearing comfort.

[0063] For example, a first cavity is formed within the first housing 111, and a sound-generating module is disposed within the first cavity. A second cavity is formed within the second housing 112, and a battery is disposed within the second cavity.

[0064] It should be noted that a circuit board can also be installed inside the second cavity. This circuit board can be electrically connected to the battery and the sound-generating module, thereby controlling the sound-generating module.

[0065] In one possible implementation, such as Figure 3 As shown, the connecting bridge 120 has a C-shaped structure.

[0066] By arranging the connecting bridge 120 in a C-shape, a gap 115 is created between the connecting bridge 120 and the user's ear 200 when the ear clip-on headphone structure 100 is worn on the user's ear 200. This prevents contact with the auricle 210 and thus avoids pain caused by the ear clip-on headphone structure 100 clamping the auricle 210 cartilage. For example, the gap 115 between the connecting bridge 120 and the user's ear 200 is typically between 1 mm and 5 mm.

[0067] In one possible implementation, the length of the connecting bridge 120 is greater than 2 / 3 of the overall length of the ear clip headphone structure 100 in the extending direction of the connecting bridge 120.

[0068] For example, the length of the connecting bridge 120 is greater than 65%, 70%, 75%, etc., of the overall length of the ear clip-on headphone structure 100. In this embodiment, the proportion of the length of the connecting bridge 120 to the overall length of the ear clip-on headphone structure 100 is not further limited.

[0069] By setting the length of the connecting bridge 120 to be greater than 2 / 3 of the overall length of the ear clip-on headphone structure 100 in the extension direction of the connecting bridge 120, the proportion of the connecting bridge 120 can be increased. Since the connecting bridge 120 is an elastic structure, this can increase the proportion of the elastic structure. The area that the connecting bridge 120 can deform is larger, so it can adapt to a greater degree of deformation, thereby adapting to more users with different ear shapes and improving adaptability.

[0070] In one possible implementation, such as Figure 2 As shown, one end of the inner core 123 is fixedly connected to the first housing 111, and the other end is fixedly connected to the second housing 112. One end of the outer wall 124 is fixedly connected to the first housing 111, and the other end is fixedly connected to the second housing 112. The inner core 123 is a memory metal wire, which is elastic.

[0071] By fixing the two ends of the inner core 123 to the first housing 111 and the second housing 112 respectively, and connecting the two ends of the outer wall 124 to the first housing 111 and the second housing 112 respectively, the connection stability between the connecting bridge 120 and the first housing 111 and the second housing 112 can be increased, thereby improving the structural strength of the ear clip-on headphone structure 100 and extending its service life. The outer wall 124, located on the outside of the inner core 123, provides protection for the inner core 123 and facilitates shaping and selection of skin-friendly materials, thus enhancing wearing comfort.

[0072] For example, the connecting bridge 120 can be formed by nano-injection molding. In this embodiment of the application, the forming method of the connecting bridge 120 is not further limited.

[0073] It should be noted that, in the embodiments of this utility model, "memory metal wire" refers to an elastic metal component with "memory" shape function, which can deform under external force and can completely restore the original pre-constructed shape after the external force is removed.

[0074] In one possible implementation, the shape memory wire is a titanium wire or a titanium alloy wire.

[0075] This design enhances the comfort of the clip-on earphone structure 100. The memory titanium wire, with its excellent elasticity and flexibility, can adjust to the shape of the wearer's ear 200, providing a more comfortable wearing experience. The memory titanium wire boasts high strength and fatigue resistance, able to withstand repeated bending and stretching without breaking, extending the earphone's lifespan. Its low density makes the earphone lighter overall, reducing the burden during extended wear. The memory titanium wire can return to its preset shape at specific temperatures, meaning the earphone can maintain a compact shape when not in use, facilitating storage and portability. Titanium has excellent corrosion resistance, remaining stable in humid environments and resistant to rust, making it suitable for long-term use. The memory titanium wire remains stable within a wide temperature range, ensuring that changes in ambient temperature do not affect the earphone's performance.

[0076] In one possible implementation, the diameter of the shape memory wire is between 0.4 mm and 0.6 mm. For example, the diameter of the shape memory wire can be 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, or 0.6 mm.

[0077] It's worth noting that the 0.4mm-0.6mm memory titanium wire is relatively thin, making it suitable for headphone components requiring delicate and complex designs, such as ear hooks and headphone frames, enabling more intricate structures. The thinner titanium wire further reduces the weight of the headphones, making them lighter and more portable, with almost no burden felt when wearing them, thus improving user comfort. The 0.4mm-0.6mm memory titanium wire has good flexibility, allowing it to better conform to the shape of the ear, improving wearing stability and comfort. Despite its small diameter, the memory titanium wire maintains high strength and fatigue resistance, able to withstand repeated bending and stretching without easily breaking, extending the headphone's lifespan. The thin diameter memory titanium wire effectively returns to its preset shape when temperature changes, allowing the headphones to maintain a compact form when not in use, facilitating storage and portability. Titanium itself has excellent corrosion resistance; the 0.4mm-0.6mm memory titanium wire remains stable in humid environments, is not prone to rust, and is suitable for long-term use. Thinner titanium wires perform well in terms of thermal conductivity, enabling them to respond more quickly to temperature changes and achieve rapid shape memory effects.

[0078] For example, the outer wall 124 can be a soft rubber wall. For instance, the soft rubber wall is a silicone wall or a rubber wall, etc.

[0079] By using a soft rubber outer wall 124, the excellent softness and elasticity of the material allow it to better conform to the shape of the ear 200, reducing pressure and improving wearing comfort. Soft rubber typically has a high coefficient of friction, effectively preventing the headphones from slipping off during wear and providing a more stable wearing experience, especially suitable for sports. Soft rubber also boasts good abrasion and tear resistance, withstanding the pulling and bending of daily use and extending the headphones' lifespan. Furthermore, the generally lightweight nature of soft rubber does not increase the overall weight of the headphones, reducing the burden of wearing them and making them suitable for extended use.

[0080] By using silicone or rubber as the soft inner wall, the wearing comfort of the clip-on earphone structure 100 can be improved, as silicone is a biocompatible material that does not irritate the skin. Silicone has excellent UV and oxidation resistance, is not prone to aging, and has a long service life. Silicone material is very soft, making it suitable for applications requiring high softness and comfort. The smooth surface of silicone is easy to clean and maintain. Rubber has excellent elasticity and flexibility, can withstand large deformations without damage, and is suitable for shock absorption and sealing materials.

[0081] It should be noted that "soft" refers to the property of being able to stretch and deform, and having elasticity so that it can return to its original shape after deformation.

[0082] In one possible implementation, the first housing 111 and the second housing 112 are movably configured, and the first housing 111 can switch between a first position and a second position relative to the second housing 112. For example... Figure 4 As shown, when the first housing 111 is in the first position, the included angle between the first end 121 and the second end 122 of the connecting bridge 120 is 3.5°. Figure 5 As shown, when the first housing 111 is in the second position, the angle between the first end 121 and the second end 122 of the connecting bridge 120 is 10°. When the first housing 111 moves relative to the second housing 112, it passes through at least the first position and the second position.

[0083] It should be noted that since the first housing 111 and the second housing 112 are connected by a connecting bridge 120, and the connecting bridge 120 is elastic, it can drive the first housing 111 and the second housing 112 to move relative to each other. For example, the first housing 111 and the second housing 112 can be moved closer to each other by pressing them. Alternatively, the first housing 111 and the second housing 112 can be moved further apart by pulling them. During the process of driving the first housing 111 and the second housing 112 closer to each other or further apart, the included angle between the first end 121 and the second end 122 of the connecting bridge 120 is between 3.5° and 10°.

[0084] It should be noted that the included angle between the first end 121 and the second end 122 of the connecting bridge 120 refers to the included angle between the tangent of the outer edge of the first end 121 of the connecting bridge 120 where it connects to the first housing 111 and the tangent of the outer edge of the second end 122 of the connecting bridge 120 where it connects to the second housing 112.

[0085] This design allows the angle between the first end 121 and the second end 122 of the connecting bridge 120 to be changed. In other words, the clamping space between the first housing 111 and the second housing 112 can be increased or decreased, thus making it suitable for more people with different ear sizes.

[0086] In one possible implementation, see [link to previous section] Figure 1 As shown, the side of the second housing 112 facing the first housing 111 is an inwardly concave arc-shaped surface 114.

[0087] By setting the side of the second housing 112 facing the first housing 111 as an inwardly concave arcuate surface 114, such as Figure 6As shown, since the auricle 210 of the ear 200 is concave inward, the second shell 112 can fit more closely to the back of the auricle 210 of the ear 200, which is more in line with the natural shape of the ear 200, and can better fit the ear 200, providing a more comfortable wearing experience and reducing the discomfort caused by wearing for a long time.
