Description

Technical Field

[0001] This utility model relates to a flared sponge earphone cover, belonging to the field of earphone cover technology. Background Technology

[0002] With the continuous advancement of technology, electronic products (such as smartphones, tablets, portable music players, etc.) have become deeply integrated into people's daily lives and work. Headphones, as the core audio output accessory of electronic products, can help users clearly listen to the sounds (such as music, voice calls, audio content, etc.) emitted by electronic products without external interference. They have become an essential piece of equipment for users when using electronic products in various scenarios such as commuting, exercising, working, and at home.

[0003] As a key component of headphones, the core functions of foam ear tips are: on the one hand, to form a sealed space by fitting snugly against the user's ear canal, reducing the intrusion of external environmental noise and preventing sound from the headphone driver unit from leaking out; on the other hand, to improve wearing comfort through the softness of its material and to ensure effective sound transmission from the driver unit to the ear canal through structural adaptation, directly affecting the headphone's sound quality performance (including high-frequency resolution, low-frequency fullness, mid-frequency stability, etc.) and wearing stability.

[0004] However, current foam earphone covers still have many shortcomings in terms of structural design and performance adaptation, making it difficult to meet users' needs for high-quality sound and a stable wearing experience. The specific defects are as follows: Existing foam earphone covers typically have a short silicone portion, and the foam used to wrap the earphone shaft directly covers or is close to the sound transmission path. Due to the porous structure of the foam's sound wave absorption properties, it easily over-absorbs high-frequency sound waves emitted by the earphone driver unit, resulting in the loss of high-frequency details, blurred sound layering, and ultimately a "muddy" listening experience.

[0005] Existing earphone covers lack a dedicated sound energy converging structure, causing the sound energy emitted by the earphone driver unit to easily diffuse into irrelevant areas outside the ear canal, failing to accurately direct the sound energy deep into the ear canal. This not only reduces sound transmission efficiency but also results in poor sound field positioning, making it difficult for users to clearly distinguish the location of the sound source and disrupting the immersive listening experience. Utility Model Content

[0006] This invention provides a horn-shaped foam earphone cover to solve the problems of muddy high-frequency sound quality, poor resolution, dispersed sound energy transmission, and blurred sound field positioning in the prior art.

[0007] This utility model provides a horn-shaped foam earphone cover, which includes an earbud body, an amplification part for amplifying sound on the earbud body, the amplification part being located at the top of the earbud body in a horn shape, an axial through hole communicating with the amplification part inside the earbud body, a ring-shaped memory foam on the outside of the earbud body, and an anti-blocking component inside the amplification part.

[0008] Preferably, the earbud body and the sound amplification part are both polished and made of hard silicone material.

[0009] Preferably, the earbud body and the sound amplification part are both polished and made of metal.

[0010] Preferably, the opening angle of the amplification part is 15°~45°.

[0011] Preferably, the memory foam is located on the side of the earbud body away from the amplification part.

[0012] Preferably, the memory foam is arranged in a horizontal ring on the earbud body.

[0013] Preferably, the anti-blocking component includes a base, an outer isolation pad, an adhesive component, and an inner isolation pad. The base is fixedly connected to the amplifier unit. The inner and outer isolation pads are located inside the base. The inner isolation pad is connected to the base via the adhesive component. The outer isolation pad is located above the inner isolation pad and is connected to the inner isolation pad via the adhesive component.

[0014] Preferably, the outer isolation pad has multiple sound transmission holes that match the headphones, the outer isolation pad is in the form of a metal mesh, and the inner isolation pad is a water-resistant layer.

[0015] Preferably, the memory foam has multiple anti-slip protrusions, which are distributed circumferentially on the memory foam.

[0016] The beneficial effects of this utility model are: This invention provides a horn-shaped foam earphone cover. The earphone body and the sound amplification section are made of polished hard silicone or metal, reducing random reflections and diffusion losses of high-frequency sound waves during propagation. This avoids the "muddy" sound caused by the porous structure of traditional foam earphone covers absorbing high frequencies. The memory foam is located on the side of the earphone body away from the sound amplification section, in a horizontal ring design, eliminating the absorption of high-frequency sound waves by the porous structure of the foam and further ensuring the purity of high-frequency sound quality. The sound amplification section has a horn-shaped opening of 15°~45°, which can more effectively transfer the vibration energy of the driver unit into the air, significantly improving the sound pressure level. When the opening angle is 15°~30°, the sound energy transmission is more concentrated, reducing sound dispersion, improving low-frequency energy locking efficiency, and improving the sound field positioning. When the opening angle is 30°~45°, it can better fit the ear canal space, conforming to the memory foam and avoiding conflict with the ear canal wall, ensuring sealing efficiency. The earphone body has an axial through hole that penetrates the sound amplification section, ensuring sound... The sound transmission path from the driver unit to the ear canal is minimized, reducing energy loss and improving sound transmission efficiency. The memory foam material is soft and malleable, dynamically adapting to different ear shapes within the ear canal. Even with irregular ear canals or improper wearing methods, it automatically fills gaps through compression and rebound, effectively preventing air leakage, firmly locking in sound pressure, and maintaining complete low-frequency energy transmission. The memory foam features multiple circumferentially distributed silicone anti-slip protrusions, increasing the contact area with the ear canal skin, ensuring stability even in sweaty conditions, preventing the earbuds from slipping or falling out, and enhancing the user experience. The amplifier section incorporates anti-blocking components, including a metal mesh outer isolation pad and a water-resistant inner isolation pad. The outer isolation pad effectively blocks earwax, dust, and other foreign objects from entering the amplifier section, preventing axial through-holes and earphone blockage. At the same time, the metal mesh structure has an acoustic damping effect, optimizing high-frequency sound wave diffusion and reducing sound quality attenuation. The inner isolation pad is a water-resistant layer, preventing sweat from seeping into the earphone, avoiding moisture damage to electronic components, and extending the earphone's lifespan.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 This utility model proposes a horn-shaped foam earphone cover, including an earphone body 1, an amplification part 2 on the earphone body 1 for amplification, the amplification part 2 is located at the top of the earphone body 1 in a horn shape, an axial through hole 11 is provided in the earphone body 1, the top of the axial through hole 11 is interconnected with the amplification part 2, the earphone body 1 is fixed to the earphone through the bottom of the axial through hole 11, and a memory foam 3 is provided on the outside of the earphone body 1, the memory foam 3 is located on the earphone body 1 in a horizontal ring design, and the memory foam 3 is located on the side of the earphone body 1 away from the amplification part 2. The earbud body 1 and the amplification part 2 have smooth surfaces made of polished hard silicone or metal, with aluminum alloy or titanium alloy being preferred. The opening angle of the amplification part 2 is preferably 15°~45°. When the opening angle of the amplification part 2 is 15°~30°, the sound energy transmission is more concentrated, the sound dispersion is reduced, and the vibration energy of the driver unit can be more accurately directed to the ear canal, improving the low-frequency energy locking efficiency, preventing the sound from spreading to irrelevant areas outside the ear canal, and improving the sound field positioning. When the opening angle of the amplification part 2 is 30°~45°, it can better fit the ear canal space, better fit the memory foam 3, avoid conflict with the ear canal wall, ensure the sealing effect of the memory foam 3, and at the same time, not affect the high frequency transmission.

[0024] In use, the earbud body 1 is fitted onto the earphone through the bottom of the axial through-hole 11. The earbud body 1 is then inserted into the ear canal. The memory foam 3 deforms and conforms to the ear canal. The memory foam 3 is soft and malleable, dynamically adapting to different ear shapes within the ear canal. Even if the ear canal is irregular or the wearing method is not standard, it can automatically fill gaps by compressing and rebounding, effectively preventing air leakage and firmly locking the sound pressure emitted by the earphone unit, maintaining the complete transmission of low-frequency energy. Because the memory foam 3 provides a certain degree of support within the ear canal and is not easily loosened or shifted due to head movements, it is highly effective. Therefore, the mid-frequency sound image position is stable, and the fullness and thickness of the sound can be maintained, preventing frequency response fluctuations caused by improper wearing. The memory foam 3 is located on the earbud body 1 in a ring design. The memory foam 3 is far away from the amplification part 2, which can prevent the porous structure of the foam from absorbing high frequencies and causing high-frequency muddiness. The earbud body 1 is equipped with the amplification part 2, which is horn-shaped. The earbud body 1 is made of polished hard silicone material or metal material, which can better fix it on the headphones. When transmitting sound waves, there is almost no material absorption or energy dissipation. The sound energy is transmitted to the ear canal more directly, especially the high-frequency details are clearer and the resolution is higher. The hard and smooth surface reduces the random reflection and diffusion loss of the high-frequency part. The amplification part 2 can more effectively transmit the vibration energy of the driver unit into the air, greatly improving the sound pressure level. Under the same input power, the sound is louder and farther, and mechanical distortion and compression distortion can be reduced.

[0025] Compared to existing technologies, the amplifier section 2 is horn-shaped, which can more effectively transfer the vibration energy of the driver unit into the air, significantly improving the sound pressure level. At the same input power, the sound is louder and farther-reaching, reducing mechanical and compression distortion. The opening angle of the amplifier section 2 is preferably 15°~45°. When the opening angle is 15°~30°, the sound energy transmission is more concentrated, reducing sound dispersion. It can more accurately guide the vibration energy of the driver unit to the ear canal, improving low-frequency energy locking efficiency, preventing sound from spreading to irrelevant areas outside the ear canal, and improving the sound field positioning. When the opening angle of the amplifier section 2 is 30°~45°, it can better fit the ear canal space, better conform to the memory foam 3, avoid conflict with the ear canal wall, ensure the sealing effect of the memory foam 3, and not affect high-frequency transmission. The earbud body 1 has a smooth surface and is made of polished hard silicone material or metal material, with aluminum alloy or titanium alloy being preferred metal materials. This hard, smooth surface reduces random reflections and diffusion losses in the high-frequency range. There is almost no material absorption or energy dissipation during sound wave transmission, allowing sound energy to be transmitted more directly to the ear canal. High-frequency details are clearer, resulting in higher resolution. The earbud body 1 is surrounded by memory foam 3, which is designed in a horizontal ring on the earbud body 1 and located on the side away from the amplifier section 2. The memory foam 3 is soft and malleable, dynamically adapting to different ear shapes within the ear canal. Even with irregular ear canals or improper wearing methods, it can automatically fill gaps by compressing and rebounding, effectively preventing air leakage and firmly locking the sound pressure emitted by the headphone unit, maintaining the complete transmission of low-frequency energy. Because the memory foam 3 provides support within the ear canal and is not easily loosened or shifted due to head movements, the mid-frequency sound image position is stable, maintaining the fullness and thickness of the sound and preventing frequency response fluctuations caused by improper fit. The ring-shaped design of the memory foam 3 on the earbud body 1, away from the amplifier section 2, prevents the porous structure of the foam from absorbing high frequencies and causing high-frequency muddiness.

[0026] Example 2 Based on Embodiment 1, this embodiment further includes multiple anti-slip protrusions 31 on the memory foam 3, which are circumferentially distributed on the memory foam 3. The anti-slip protrusions 31 are made of silicone material. The sound amplification part 2 is provided with an anti-blocking component 21 that matches the headphones. The anti-blocking component 21 includes a base 211, which is fixedly connected to the sound amplification part 2. The base 211 is provided with an outer isolation pad 212 and an inner isolation pad 214. The outer isolation pad 212 and the inner isolation pad 214 are arranged vertically inside the base 211. The inner isolation pad 214 is connected to the base 211 by an adhesive component 213. The outer isolation pad 212 and the inner isolation pad 214 are bonded and fixed by the adhesive component 213. The outer isolation pad 212 is provided with multiple sound transmission holes that match the headphones. The outer isolation pad 212 is in the form of a metal mesh, and the inner isolation pad 214 is a water-resistant layer.

[0027] When in use, the earphone is fixed at the bottom of the axial through hole 11, and the earbud body 1 is fitted onto the earphone. Multiple anti-slip protrusions 31 on the memory foam 3 form a dynamic fit with the ear canal skin. The three-dimensional structure of the protrusions increases the contact area and can remain stable even in sweaty situations. When the earbud body 1 is inserted into the ear canal, it is blocked by the outer isolation pad 212 to prevent foreign objects from entering the amplification part 2 and causing blockage of the axial through hole 11 and the earphone. The acoustic damping effect of the mesh structure can optimize the diffusion of high-frequency sound waves and reduce the sound quality attenuation that may be caused by traditional dustproof mesh. The inner isolation pad 214 is a water-proof layer and can be made of breathable and waterproof nylon material. When in use, it can effectively prevent external sweat from seeping into the earphone and avoid damaging the electronic components inside.

[0028] Compared with existing designs, the memory foam 3 has multiple anti-slip protrusions 31, and these protrusions 31 are arranged in a circular pattern on the memory foam 3, which changes the contact between the memory foam 3 and the ear canal skin from the traditional planar contact to a three-dimensional protruding contact, greatly expanding the contact area. The anti-slip protrusions 31 are made of silicone, which has good flexibility and friction. Even in sweaty situations, it can dynamically conform to the skin of the ear canal. The three-dimensional structure of the protrusions increases friction, thereby effectively preventing the earplug from sliding or falling off, ensuring the stability of the earplug during use, and improving the user experience. The inner isolation pad 214 is a water-proof layer, which can be made of breathable and waterproof nylon material. During use, the inner isolation pad 214 can effectively prevent external sweat from seeping into the earphone, avoiding damage to electronic components due to moisture and extending the service life of the earphone. During use, earwax, dust and other foreign objects in the ear canal can easily enter the amplification part 2, thereby blocking the axial through hole 11 and the earphone, affecting the sound propagation and causing a decrease in sound quality. The amplification part 2 is equipped with an anti-blocking component 21 that matches the earphone. When the earplug body 1 is inserted into the ear canal, the outer isolation pad 212 can effectively block foreign objects from entering the amplification part 2, preventing the axial through hole 11 and the earphone from being blocked. Meanwhile, the metal mesh structure has an acoustic damping effect, which can optimize the diffusion of high-frequency sound waves, reduce the sound quality attenuation that may be caused by traditional dustproof mesh, ensure high-quality sound transmission, and enhance the user's auditory experience.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
