[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0019] The present invention provides the following technical solution: a wired earphone with high wearing comfort, which has both excellent wearing comfort and stability during use: medical-grade liquid silicone ear caps and anti-slip texture on the inner wall avoid ear canal pressure and prevent the earphone from falling out; adjustable crescent-shaped wings adapt to different ear shapes, further reducing local discomfort and meeting the needs of long-term wearing for more than 4 hours.

[0020] Figures 1-4 The diagram shown is a structural schematic of a first embodiment of a wired headphone with high wearing comfort according to the present invention. Please refer to [link / reference]. Figures 1-4 This embodiment provides a wired headphone with high wearing comfort, including a headphone shell 100, ear tips 120, a wire 140, a controller 150, and a plug 160. The specific structure and connection relationship are as follows: The earphone shell 100 is composed of a rear cover 101 and a front cover 102 of the sound chamber, which are fixedly connected by snaps or screws. The interior forms a sealed sound chamber to accommodate the sound-producing unit such as a dynamic unit, ensuring sound quality output. The outer side of the front cover 102 of the sound cavity is integrally formed with a snap connector 110 and a crescent-shaped wing 130: the snap connector 110 is a ring-shaped protrusion structure for detachable installation of ear caps 120, making it convenient for users to replace ear caps 120 of different sizes; the crescent-shaped wing 130 is an arc-shaped sheet structure that fits the outer side of the user's concha cavity and plays an auxiliary fixing role to prevent the earphone from falling off. The Moon Wing 130 adopts a composite structure of "high-strength inner shell 121 and flexible outer shell 122": the high-strength inner shell 121 is made of polycarbonate (lightweight and bend-resistant), and the flexible outer shell 122 is made of silicone (fits the skin without discomfort); and the end of the Moon Wing 130 away from the front cover 102 of the sound cavity is rotatably connected to the outer wall of the front cover 102 of the sound cavity through a damping pivot, with an adjustable angle range of 0-30° (damping coefficient 5-8 N·m / rad). Users can rotate the Moon Wing 130 according to their own ear shape to adapt to different concha curvatures and reduce local pressure.

[0021] The ear cap 120 is press-fitted with the snap connector 110 of the front cover 102 of the sound chamber through the inner hole, and can be easily disassembled and replaced to fit S / M / L sizes; The ear cap 120 also adopts the structure of "high-strength inner shell 121 and flexible outer shell 122": the flexible outer shell 122 is made of medical-grade liquid silicone material (good biocompatibility, no risk of allergies, and soft to the touch), and the inner wall of the flexible outer shell 122 is uniformly set with arc-shaped anti-slip texture (texture depth 0.1-0.3mm, texture spacing 0.5-1mm) - the anti-slip texture can enhance the friction between the ear cap 120 and the inner wall of the ear canal, preventing the earphone from falling off due to head shaking. At the same time, the arc design will not produce local pressure, improving the comfort of wearing for a long time. The bottom of the front cover 102 of the sound cavity has a wire hole. One end of the wire 140 passes through the wire hole and is electrically connected to the internal sound unit, and the other end is fixedly connected to the controller 150. The wire 140 is made of TPE material, which is soft, flexible and resistant to bending, and not easy to tangle. An optional anti-tangle braided mesh can be wrapped around the outer layer to improve durability. The controller 150 has a rectangular plastic shell (approximately 40×20×10mm in size, easy to operate with one hand). The shell integrates a microphone 151 and control buttons 152: the microphone 151 has a built-in noise-canceling microphone that can filter out ambient noise and improve call clarity; the control buttons 152 include a pause / play button (centered, long press to wake up the voice assistant), a fast forward button (right side), and a rewind button (left side). Users can directly control audio playback through the buttons without operating the device itself. The end of the controller 150 furthest from the wire 140 is connected to the plug 160 via a control line (the plug 160 can be either a 3.5mm national standard plug 160 or a Type-C plug 160, suitable for different devices); a bend-resistant sleeve 170 is provided at the connection between the control line and the plug 160—the bend-resistant sleeve 170 is a one-piece molded TPU soft sleeve (highly flexible and resistant to aging), 15-20mm in length, and a tapered transition section (taper 1:3) is provided at the end of the bend-resistant sleeve 170 near the plug 160: the tapered transition section can disperse the stress when the control line is bent, avoid the breakage of the copper core inside the wire 140 caused by the traditional right-angle transition, and extend the service life of the control line.

[0022] Headphone housing 100 assembly: Fix the sound unit (such as a 10mm dynamic unit) in the mounting groove inside the front cover 102 of the sound cavity, and solder one end of the wire 140 to the pin of the sound unit; fasten the rear cover 101 of the sound cavity to the front cover 102 of the sound cavity and fix it with two M2 screws (to ensure the sound cavity is sealed and reduce sound leakage). Moon Wing 130 Installation: Insert the fixed end of the damping shaft into the shaft hole on the outside of the front cover 102 of the sound cavity, and the movable end is interference-fitted with the reserved hole of the moon wing 130. Rotate the moon wing 130 to test: ensure smooth rotation within the range of 0-30°, and maintain the angle stably after stopping the rotation (damping coefficient meets the requirement of 5-8 N·m / rad). Assemble the ear cap 120 with the controller 150: Align the inner hole of the ear cap 120 with the snap connector 110 of the front cover 102 of the sound cavity, and press it until it fits completely (ensure there is no looseness); pass the other end of the wire 140 through the inlet hole of the controller 150 and solder it to the internal PCB board, and use hot melt glue to fix the connection between the wire 140 and the outer shell of the controller 150 (avoid pulling that may cause the solder joint to fall off). Assemble the anti-bend sleeve 170 and plug 160: Slide the anti-bend sleeve 170 onto the control line from the plug 160 end. Solder one end of the control line to the PCB board of the controller 150 and the other end to the pin of the plug 160. Push the anti-bend sleeve 170 to the connection point between the control line and the plug 160. Heat the anti-bend sleeve 170 with a hot air gun (temperature 80-100℃) to make it fit tightly against the control line and the plug 160 (ensure that the tapered transition section completely covers the bending area).

[0023] Combination Figures 1-4 The working principle of this embodiment of a wired headphone with high wearing comfort is as follows: 1. Principles of Audio Signal Transmission and Playback Signal reception and transmission: After plug 160 is inserted into the audio interface of a device (such as a mobile phone or computer), the audio electrical signal output by the device is transmitted to the controller 150 through the control line; after the PCB board inside the controller 150 performs preliminary processing on the signal (such as filtering and gain adjustment), it is transmitted to the sound unit (such as a dynamic unit) inside the earphone shell 100 through the wire 140. Sound quality assurance: The sealed acoustic cavity formed by the rear cover 101 and the front cover 102 of the acoustic cavity can avoid sound wave leakage caused by the vibration of the sound unit and reduce sound quality distortion; at the same time, the "semi-sealed acoustic environment" formed by the ear cap 120 fitting the ear canal further enhances the low frequency extension and mid frequency clarity, and improves the overall listening experience.

[0024] 2. Call pickup and control principle Noise reduction and voice pickup: During a call, the user's voice signal is transmitted through the air to the pickup port 151 of the controller 150. The built-in noise reduction microphone converts the voice signal into an electrical signal. At the same time, the "ambient sound filtering algorithm" (integrated into the controller 150 PCB board) suppresses ambient noise (such as wind noise and crowd noise), and then transmits the processed voice signal back to the device to achieve clear calls. Audio control: When the control button 152 of the controller 150 is pressed, the button triggers the internal micro switch to generate the corresponding control signal (such as pause signal, fast forward signal). The signal is transmitted to the device through the control line. The device performs the corresponding operation according to the signal instruction (such as pausing playback, switching to the next track); when the pause / play button is pressed and held, the voice assistant wake-up signal is triggered to adapt to the voice interaction function of the device.

[0025] 3. The principle of wearing stability and comfort adaptation Multi-dimensional fixation: After the ear cap 120 is inserted into the ear canal, the medical-grade liquid silicone of the flexible shell 122 fits the ear canal skin in a flexible manner, avoiding the pressure caused by hard contact; at the same time, the arc-shaped anti-slip texture on the inner wall of the ear cap 120 increases the static friction with the inner wall of the ear canal, preventing the earphone from falling off due to head shaking (such as walking or running). Ear shape adaptation adjustment: Users can rotate the crescent-shaped wing 130 through the damping pivot to adjust the angle between it and the front cover 102 of the sound cavity (within the range of 0-30°), so that the arc surface of the crescent-shaped wing 130 completely fits the outer contour of their own concha cavity. Different users have different concha cavity curvatures. The adjustable design allows the crescent-shaped wing 130 to form an "auxiliary support point", which not only avoids local pressure, but also further improves wearing stability and adapts to the ear shape of most people. 4. Durability Protection Principle Wire 140 bend protection: The connection between the control wire and the plug 160 is a high-frequency bending area (such as when plugging, unplugging, or storing). The one-piece molded TPU anti-bend sleeve 170 disperses the bending stress to a larger area through a "conical transition section" (the stress of a traditional right-angle transition is concentrated at one point, which can easily lead to copper core breakage). At the same time, the high flexibility of the TPU material can deform with the bending of the wire 140, preventing the protective sleeve itself from cracking. Enhanced damage resistance of conductor 140: The TPE material conductor 140 has excellent bending resistance (can withstand more than 10,000 bending tests), and the outer anti-tangling braided mesh (optional) can reduce wear when conductor 140 is pulled, and extend the overall service life of conductor 140.
