Description

Technical Field

[0001] This utility model relates to the field of headphones, and in particular to semi-open headphones. Background Technology

[0002] Semi-open headphones, as an audio device that balances sound quality and environmental awareness, are widely used in daily commutes, sports and fitness activities, and business calls. Their design features include retaining some ambient sound input to ensure safety while improving sound quality through optimized acoustic structure. As users increasingly demand comfort, call clarity, and adaptability to different sports activities, semi-open headphones need further breakthroughs in structural design, material selection, and acoustic performance.

[0003] Traditional ear hooks are mostly made of hard plastic or a single elastic material, which can easily cause ear pressure and pain when worn for a long time. They also lack the ability to adapt to different ear shapes and are prone to loosening and falling off during exercise. The semi-in-ear structure often suffers from serious low-frequency leakage and thin sound quality due to the unreasonable position of the sound outlet. On the other hand, the overly closed design will lose the ability to perceive the environment, affecting the safety of outdoor use. The microphone is mostly exposed on the surface of the earphone, which is easily affected by wind noise and environmental noise. The call quality drops sharply, especially in scenarios such as running and cycling. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a semi-open earphone, which can effectively solve the technical problems of ear compression and susceptibility to wind noise and environmental noise interference.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The semi-open earphone includes an earpiece, an ear clip, and an ear hook. A speaker element is housed within the earpiece. The ear hook is fixedly connected to both ends of the earpiece and the ear clip, respectively, and is elastically deformable. A buffer groove and an air suspension are formed on the surface of the ear hook. The air suspension is made of silicone and can be compressed towards the buffer groove to deform it. An earbud is located inside the earpiece. The earpiece and earbud are internally connected and form a receiving cavity. The speaker element is located at one end of the receiving cavity near the earbud. The surface of the earbud has a sound outlet and a microphone hole. The microphone hole is located inside the earbud, corresponding to the position of the speaker element. The microphone hole is located outside the earbud. When worn, the earbud is located within the ear clip cavity of the user's ear, with the sound outlet and speaker element aligned with the ear canal, and the microphone hole located below the tragus.

[0007] Furthermore, the ear hook is composed of an inner skeleton and a silicone layer. The inner skeleton is made of elastic metal, and the silicone layer covers the surface of the inner skeleton. The air suspension, buffer channel and silicone layer are integrally formed.

[0008] Furthermore, the cross-sections at both ends of the ear loop gradually increase in size compared to the cross-section of the middle section.

[0009] Furthermore, the air suspension and buffer channel are located at one end of the ear hook near the earpiece.

[0010] Furthermore, the cavity contains a main control circuit board, a battery, and charging terminals, and the speaker components, battery, and charging terminals are all electrically connected to the main control circuit board.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: The air suspension of the ear hook has high elasticity and deformation recovery capability, which can adaptively fit according to different users' ear shapes, disperse ear pressure, and avoid the oppressive feeling of traditional rigid ear hooks. The compression deformation of the air suspension into the buffer groove further absorbs the impact of exercise, forming a double buffer with the elastic ear hook, ensuring a stable fit in high-intensity scenarios such as running and fitness, and no discomfort even after long-term use. The semi-open structure of the earbud allows the sound hole to be precisely aligned with the ear canal entrance, reducing sound leakage through directional sound wave conduction, while avoiding the ear canal blockage feeling of fully in-ear earbuds, balancing sound clarity and wearing comfort. After wearing, the microphone hole is hidden under the tragus, utilizing the physical structure of the tragus to naturally block lateral wind noise and environmental noise.

[0016] 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.

[0017] The following is combined Figures 1-3 The present invention provides a detailed description of the semi-open headphone:

[0018] The semi-open earphone includes a receiver 1, an ear clip 2, and an ear hook 3. A speaker element 5 is housed inside the receiver 1. The two ends of the ear hook 3 are fixedly connected to the receiver 1 and the ear clip 2, respectively. The ear hook 3 is elastically deformable. A buffer groove 6 and an air suspension 7 are formed on the surface of the ear hook 3. The air suspension 7 is made of silicone and can be pressed towards the buffer groove 6 to deform it. An earbud 4 is located inside the receiver 1. The receiver 1 and the earbud 4 are internally connected and form a receiving cavity. A main control circuit board, a battery 10, and charging terminals are housed within the receiving cavity. 11. The speaker element 5, battery 10 and charging terminal 11 are all electrically connected to the main control circuit board. The speaker element 5 is located at one end of the receiving cavity near the earplug part 4. The design of the speaker element 5 near the earplug part 4 shortens the sound wave transmission path. The surface of the earplug part 4 is provided with a sound outlet 8 and a microphone hole 9. The microphone hole 9 is located on the inner side of the earplug part 4. The sound outlet 8 corresponds to the position of the speaker element 5. The microphone hole 9 is located on the outer side of the earplug part 4. When the user wears it, the inner side of the earplug part 4 is located in the ear clip cavity of the user's ear. The sound outlet 8 and the speaker element 5 are aligned with the ear canal. The microphone hole 9 is located under the tragus.

[0019] The silicone air suspension 7 of the ear hook 3 has high elasticity and deformation recovery capabilities, which can adaptively fit different users' ear shapes, distribute ear pressure, and avoid the oppressive feeling of traditional rigid ear hooks. The compression deformation of the air suspension 7 towards the buffer groove 6 further absorbs the impact of exercise, forming a double buffer with the elastic ear hook 3, ensuring a stable fit in high-intensity scenarios such as running and fitness, and no discomfort even after long-term use. The semi-open structure of the earbud 4 allows the sound outlet 8 to be precisely aligned with the ear canal entrance, using directional sound wave conduction to reduce sound leakage, while avoiding the ear canal blockage feeling of fully in-ear earbuds, balancing sound clarity and wearing comfort. After wearing, the microphone hole 9 is hidden under the tragus, using the physical structure of the tragus to naturally block lateral wind noise and environmental noise.

[0020] The ear hook 3 is composed of an inner skeleton and a silicone layer. The inner skeleton is made of elastic metal, and the silicone layer covers the surface of the inner skeleton. The air suspension 7, the buffer groove 6, and the silicone layer are integrally molded. The composite structure of the elastic metal inner skeleton and the silicone layer ensures the overall support strength of the ear hook and provides a soft touch through the outer silicone layer. The integrally molded structure of the air suspension 7 and the buffer groove 6 simplifies the manufacturing process and ensures stable and reliable buffering performance. The elastic metal skeleton provides sufficient rebound force to ensure that the earphone can return to its original shape after multiple deformations, thus extending its service life. The cross-sections at both ends of the ear hook 3 gradually increase in size compared to the cross-section in the middle section. The thinner cross-section in the middle section maintains good elasticity, achieving a more natural wearing curvature. The air suspension 7 and the buffer groove 6 are located at the end of the ear hook 3 near the earpiece 1, focusing on buffering the upper part of the auricle where force is applied. The buffer structure can absorb the impact of movement most effectively.
