Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically to a type of over-ear headphone. Background Technology

[0002] In today's fast-paced life, people's needs for headphones have long surpassed simple listening; they now seek comfort and a quiet experience. While traditional over-ear headphones offer excellent sound quality, they are often criticized for discomfort and poor noise cancellation. Many people experience pressure on their ears and head after prolonged use, along with a feeling of stuffiness, which is especially noticeable in the sweltering summer. Furthermore, in noisy environments such as subways, buses, and offices, ordinary headphones struggle to create a quiet listening space, severely impacting the experience of listening to music, studying, or working. Utility Model Content

[0003] To address the aforementioned challenges, this invention provides a headset comprising an arc-shaped frame and headset bodies located at both ends of the arc-shaped frame. The headset body includes a first ear shell, a second ear shell, and an outer periphery of the ear shell. The first ear shell and the arc-shaped frame are rotatably connected around the Z-axis via a rotating component. The first ear shell and the second ear shell are rotatably connected around the X-axis via a ball joint structure. The outer periphery of the ear shell is arranged around the second ear shell in a non-contact coaxial assembly manner, and the outer periphery of the ear shell and the second ear shell are connected by at least one connector. The second ear shell has a hollow cavity containing a speaker. The side of the second ear shell away from the first ear shell is designed with a 5-25° angle to the Z-axis, and ear foam is fitted on the angled surface. Ear foam is also fitted on the outer periphery of the ear shell. The headset body has a microphone with a hollow open structure at the front end. The microphone has multiple layers of alternating dense and sparse nylon mesh at the diaphragm, a tapered spiral sound guide cavity embedded in the middle of the microphone, and a honeycomb porous metal layer covering the outside of the microphone.

[0004] Preferably, the rotating component includes a rotating shaft and a damping component coaxially arranged along the Z-axis. The damping component is provided with an internal thread, and the rotating shaft is provided with an external thread, with the internal thread and the external thread engaging.

[0005] Preferably, the connector is made of elastic rubber.

[0006] Preferably, the ear cotton is made of memory foam or silicone material.

[0007] Preferably, the pore size of the honeycomb porous metal layer is 0.5~0.7mm.

[0008] Preferably, a control component is provided inside the cavity, and the control component is electrically connected to the speaker.

[0009] Preferably, the connector is equipped with a power switch, a volume control button, and a mode switch button, all of which are electrically connected to the control unit.

[0010] Preferably, the bottom of the second earpiece has an audio interface and a charging interface.

[0011] Preferably, the microphone and the earphone body are connected by a waterproof sealing ring.

[0012] The beneficial effects are as follows: This application simultaneously solves the pain points of traditional over-ear headphones, such as strong pressure, stuffiness, poor ventilation, and poor noise cancellation, achieving a multi-dimensional breakthrough from structural innovation to functional upgrades. The Z-axis rotating component and X-axis ball joint connection give the headphones flexible adaptability, allowing dynamic adjustment to different head shapes and wearing postures. Combined with 5-25° angled earcups and ear cushions, it effectively disperses ear pressure, avoiding the pressure and stuffiness of prolonged wear, while delivering an excellent sound quality experience. The non-contact coaxial assembly of the earcups uses elastic rubber connectors to buffer external forces while retaining ventilation space, solving the problem of traditional headphones being airtight. By setting a hollow open structure at the microphone front end, combined with multi-layer nylon mesh, a tapered double-helix sound guide cavity, and a honeycomb porous metal layer nano-antibacterial coating, the headphone noise is significantly reduced, balancing high-fidelity sound quality and ambient sound filtering to meet the needs of diverse scenarios such as music listening and phone calls.

[0027] Example

[0028] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a cross-sectional schematic diagram of the present invention. This embodiment provides a headset, including an arc-shaped frame and headset bodies disposed at both ends of the arc-shaped frame.

[0029] The headphone body includes a first ear shell, a second ear shell, and an outer periphery of the ear shell. The first ear shell and the arc frame are connected to each other by a rotating component to rotate around the Z-axis so as to adapt to different head shapes, save storage space, and make it easy to carry. The rotating component includes a rotating shaft and a damping component arranged coaxially along the Z-axis. The damping component is provided with an internal thread, and the rotating shaft is provided with an external thread. The internal thread and the external thread cooperate to enable the damping component to move synchronously with the rotation of the rotating shaft to ensure flexible and stable rotation.

[0030] The first and second ear shells are connected by a ball joint structure to rotate around the X-axis, allowing the headphones to adapt to different head shapes and wearing postures. Specifically, the first ear shell has a ball socket and the second ear shell has a ball head. The ball head and ball socket cooperate with each other, and lubricating oil is filled between the ball head and ball socket to reduce friction and wear, and improve the service life and rotational flexibility of the ball joint.

[0031] like Figure 1 As shown, to facilitate understanding of this embodiment, a direction axis is established, with O as the origin, the Z-axis as the first direction, the X-axis as the second direction, and the Y-axis as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other, wherein the second direction is parallel to the central axis of the first ear shell.

[0032] The outer ear shell is coaxially mounted around the second ear shell using a non-contact method, and the outer ear shell is connected to the second ear shell by at least one connector, preferably three connectors evenly distributed along the circumference. This ensures the stability of the connection between the outer ear shell and the second ear shell. The connectors are made of elastic rubber, which ensures the coaxiality of the outer ear shell and the second ear shell and also provides cushioning when subjected to external forces. This non-contact coaxial assembly method provides good heat dissipation and breathability, preventing the ears from feeling stuffy and sweaty even after prolonged wear. The connector has a power switch, volume control, and mode switch. The hollow interior of the connector integrates a miniature vibration sensor, a Bluetooth transmitter, and a Bluetooth receiver. The vibration sensor detects external impacts and vibrations to the headphones, transmits the data to a mobile phone or other terminal device via the Bluetooth transmitter, and the Bluetooth receiver receives the signals from the terminal device to control the headphones to perform corresponding operations.

[0033] The second earpiece has a hollow interior cavity housing a speaker and control components. These components are electrically connected to the speaker, power switch, volume control, and mode switch. The side of the second earpiece furthest from the first earpiece is angled at 5-25° with respect to the Z-axis, ideally 10°. This design allows the earphone to better conform to the ear's contours, improving wearing comfort. An ear cushion is fitted on this angled surface. Similarly, an ear cushion made of memory foam or silicone is fitted around the outer edge of the earpiece. This soft ear cushioning on both the angled surface and the outer edge of the earpiece effectively distributes pressure around the ear, preventing ear pressure even after prolonged wear, further enhancing wearing comfort and noise isolation, while also providing an excellent sound quality experience. (See attached image.) Figure 3 As shown, the frequency response curve of the headphones provided in this embodiment exhibits excellent performance in the 10~40kHz range. The bottom of the second earcup also features an audio interface and a charging interface.

[0034] The earphone body is equipped with a microphone. The microphone's front end has an open, perforated structure. The microphone is connected to the earphone body via a waterproof sealing ring to prevent moisture from entering and damaging internal components. Inside the microphone, multiple layers of alternating dense and sparse nylon mesh are arranged at the diaphragm to initially filter low-frequency noise from the environment while allowing the voice signal to pass relatively smoothly. A tapered double-helix sound guide cavity is embedded in the center of the microphone to guide sound to the diaphragm, enhancing sound intensity and directionality. The microphone is covered with a honeycomb-shaped porous metal layer with a pore size of 0.5~0.7mm, which dampens high-frequency noise from the outside air and protects the internal structure from damage. A titanium dioxide nano-silver coating is applied to the surface of the honeycomb porous metal layer to prevent dust and stains from adhering to the metal layer surface, maintaining the ventilation and noise reduction effect of the porous layer. The nano-coating also has certain antibacterial properties, reducing bacterial growth on the microphone surface. The synergistic effect of these structures effectively improves the quality and clarity of the sound captured by the microphone. Figure 4 As shown, the noise reduction curve of the headphone microphone provided in this embodiment performs excellently in the range of 2~20k. When the user speaks, the forward sound wave reaches the diaphragm directly through the spiral sound guide cavity, while the lateral noise cancels out in phase within the cavity due to the path difference; the external porous layer and the internal filter weaken high-frequency wind noise and low-frequency interference, respectively, and the residual noise is further filtered out by the integrated DSP chip through an adaptive beamforming algorithm, ultimately achieving a balance between openness and breathability and noise reduction performance.

[0035] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
