Description

Technical Field

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

[0002] Over-ear headphones are like a thoughtful musical companion, opening up an immersive audio world for us anytime, anywhere. Whether on a bustling city street, putting them on instantly isolates you from the outside world, immersing you in dynamic pop music and making your steps lighter; or in the quiet of the night, soothing classical melodies allow you to relax your mind and body and drift into a peaceful dream. They are compatible with a variety of audio devices, working perfectly with mobile phones, computers, and music players, satisfying diverse needs such as listening to music, watching videos, and playing games, adding endless wonderful sound and color to life.

[0003] Traditional over-ear headphones have a relatively basic structure. The headband is mostly made of a single material, commonly plastic, and simply molded, lacking elasticity and cushioning design; the earcups are usually made of ordinary plastic injection molding, with a fixed shape that can only accommodate the sound unit; the sound unit is mainly a relatively simple dynamic type, with ordinary magnet and diaphragm construction, resulting in mediocre sound quality; the cable is a fixed, non-removable copper wire, and the outer sheath is easily worn; the ear pads are mostly thin foam covered with cheap leather, resulting in poor wearing comfort; the connection parts are simply fixed with screws or clips, the parts look obviously pieced together, and the overall function is limited.

[0004] Traditional over-ear headphone adjustment mechanisms suffer from numerous inconveniences. Their headband adjustments often employ simple sliding buckles, which are often crude, prone to jamming during sliding, and lack precision, making it difficult to accurately fit different head sizes. Furthermore, the buckles are mostly one-sided, resulting in uneven force distribution and causing the headband to easily tilt during adjustment. The earcups have a fixed angle, unable to flexibly adjust to the ear's contours, leading to localized pressure on the ears during prolonged wear. This not only forces users to repeatedly adjust the headphones initially, wasting time and effort, but also causes discomfort during use, leading to frequent headphone movement, impacting the audio experience, reducing listening enjoyment, and even reducing headphone usage frequency due to discomfort, thus preventing the headphones from fully utilizing their functionality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable headband structure for headphones, which aims to improve the problems of traditional headband headband adjustment structures being prone to jamming when sliding, having low adjustment accuracy, and being difficult to accurately adapt to different head sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable headband structure for headphones, including a connecting tube, wherein an adjustment component is provided inside the connecting tube, and a connecting component is provided at the bottom of the connecting tube;

[0007] The adjusting assembly includes a sliding shaft slidably connected inside the connecting cylinder. A fixing ring is fixedly connected to the side wall of the sliding shaft, and a sliding ring is slidably connected to the outer wall of the fixing ring. A retaining shaft is fixedly connected to the side wall of the sliding ring. Multiple retaining grooves are provided inside the sliding shaft, and the retaining shaft is slidably connected inside the retaining grooves. A side plate is fixedly connected to the side wall of the connecting cylinder, and a rotating shaft is rotatably connected to the side wall of the side plate. A lifting plate is fixedly connected to the top of the rotating shaft, and an operating plate is fixedly connected to the bottom of the rotating shaft. A spring is provided inside the fixing ring, with one end of the spring fixedly connected inside the fixing ring and the other end of the spring fixedly connected to the side wall of the sliding ring.

[0008] Furthermore, the connecting assembly includes a connector, which is fixedly connected to the bottom end of the slide shaft.

[0009] Furthermore, a head beam is fixedly connected to the top of the sliding shaft.

[0010] Furthermore, a turntable is fixedly connected to the bottom of the connector.

[0011] Furthermore, a connecting column is fixedly connected to the bottom of the turntable.

[0012] Furthermore, the bottom of the turntable is located on the ear shell, and the connecting column is rotatably connected inside the ear shell.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the control panel, when subjected to force, drives the rotating shaft to rotate inside the side plate and change its tilt angle, ultimately allowing the sliding shaft to slide inside the connecting cylinder, thereby changing the position of the headband to adjust the head circumference. This convenient adjustment function saves time from repeated adjustments, eliminating the need for users to go through the trouble of fitting the head circumference and adjusting comfort before each use, thus improving the user experience.

[0019] 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.

[0020] Reference Figures 1-2 The present invention provides an embodiment of an adjustable headband structure for headphones, comprising a connecting tube 1, characterized in that: an adjustment component is provided inside the connecting tube 1, and a connecting component is provided at the bottom of the connecting tube 1;

[0021] The adjustment assembly includes a sliding shaft 2, which is slidably connected inside the connecting cylinder 1. A fixing ring 7 is fixedly connected to the side wall of the sliding shaft 2, and a sliding ring 8 is slidably connected to the outer wall of the fixing ring 7. A retaining shaft 9 is fixedly connected to the side wall of the sliding ring 8. Multiple retaining grooves 16 are provided inside the sliding shaft 2, and the retaining shaft 9 is slidably connected inside the retaining grooves 16. A side plate 3 is fixedly connected to the side wall of the connecting cylinder 1, and a rotating shaft 4 is rotatably connected to the side wall of the side plate 3. A lifting plate 6 is fixedly connected to the top of the rotating shaft 4, and an operating plate 5 is fixedly connected to the bottom of the rotating shaft 4. A spring 10 is provided inside the fixing ring 7, with one end of the spring 10 fixedly connected to the inside of the fixing ring 7 and the other end of the spring 10 fixedly connected to the side wall of the sliding ring 8. The connection assembly includes a connector 12, which is fixedly connected to the bottom end of the sliding shaft 2. A head beam 11 is fixedly connected to the top of the sliding shaft 2, and a turntable 13 is fixedly connected to the bottom of the connector 12. A connecting column 14 is fixedly connected to the bottom of the turntable 13, and the bottom of the turntable 13 is located in the ear shell 15. The connecting column 14 is rotatably connected inside the ear shell 15.

[0022] Specifically, when adjusting the headband size, lightly press the control panel 5 with your finger. The control panel 5 is applied, which in turn causes the connected pivot 4 to rotate inside the side plate 3. The tilt angle of the pivot 4 changes accordingly. Because the lifting plate 6 is closely connected to the pivot 4, the angle of the lifting plate 6 also changes with the pivot 4. At this time, the lifting plate 6 will exert an upward force on the lower sliding ring 8. The sliding ring 8 is slowly lifted and slid along the track on the outer wall of the fixing ring 7. The locking pin 9 on the side wall of the sliding ring 8 also moves synchronously. When the locking pin 9 moves to a certain position, it slides out from the area enclosed by the inner side plate 3 of the sliding pin 2, releasing the locking state of the sliding pin 2. The sliding pin 2 can then slide inside the connecting tube 1, causing the headband 11 to move and achieve headband adjustment. This convenient adjustment function eliminates the need for repeated adjustments. Before each use, users no longer need to worry about fitting the headband size or finding a comfortable fit. Wearing the headphones is simpler, more comfortable, and provides a better user experience.

[0023] Working principle: When the head circumference of this headphone needs to be adjusted, the control panel 5, when subjected to force, will drive the rotating shaft 4 to rotate inside the side plate 3 and change its tilt angle. Subsequently, the angle of the lifting plate 6 will also be changed, further pushing the sliding ring 8. The sliding ring 8 will be lifted after being subjected to force and slide on the outer wall of the fixed ring 7. At this time, the locking shaft 9 on the side wall of the sliding ring 8 will follow the displacement. The movement of the locking shaft 9 will allow it to slide out from the side plate 3 inside the sliding shaft 2, thereby releasing the locking state of the sliding shaft 2, allowing the sliding shaft 2 to slide inside the connecting cylinder 1, thereby changing the position of the headband 11 to adjust the head circumference. The convenient adjustment function saves the time of repeated adjustments. Users do not need to go through a lot of trouble to fit the head circumference and adjust the comfort before each use, thus improving the user experience.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
