Description

Technical Field

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

[0002] Neckband headphones are a type of Bluetooth headset design where the neckband is made of flexible titanium memory alloy or flexible silicone, allowing for manual bending and adjustment to fit different users' neck sizes, providing personalized comfort and a secure wearing experience. Suitable for sports, commuting, and other scenarios, they ensure the headphones won't slip off easily while reducing pressure from prolonged wear.

[0003] According to the Chinese patent "Adjustable Neckband Headphones" authorization announcement number "CN220606040U", a micro motor and a cable winding component work together to tighten the headphone cable. When the headphone cable is too tight, simply pull the cable outward to a comfortable position. This is very convenient and quick, ensuring that the headphone cable will not swing during running and affect the running experience, thus improving the user's exercise experience.

[0004] In the aforementioned application, because the headphone cable is in a coiled state, pulling the headphone cable outward can easily cause damage to the headphone cable, thereby affecting the lifespan of the neckband headphones. Utility Model Content

[0005] Therefore, it is necessary to provide an adjustable neckband headphone to address the issue that pulling the headphone cable outward when it is in a coiled state can easily damage it.

[0006] The device includes: a controller with an adjustment frame fixedly connected to one side; and an adjustment mechanism comprising a winding rod rotatably connected to the inner wall of the adjustment frame, the surface of which is wound with an earphone cord. The top of the adjustment frame has annularly distributed grooves. A positioning rod is slidably connected to the inner wall of the winding rod, its surface engaging with the inner wall of the grooves. Two socket discs are fixedly connected to the inner wall of the adjustment frame, and the surface of the winding rod is rotatably connected to the inner wall of the socket discs. By moving the positioning rod away from the grooves and rotating the winding rod, the earphone cord is loosened, preventing pulling on the cord in its coiled state and thus avoiding damage, ensuring the lifespan of the earphone cord and consequently the lifespan of the neckband headphones.

[0007] In one embodiment, a first spring is fixedly connected to the top end of the positioning rod, and the top end of the first spring is fixedly connected to the inner top wall of the winding rod. The first spring pushes the positioning rod to automatically move downwards and engage with the groove, thereby positioning the winding rod and ensuring the positioning of the wound earphone cord.

[0008] In one embodiment, two wire-limiting rods are rotatably connected to the inner wall of the adjustment frame, and the surfaces of the wire-limiting rods contact the surface of the headphone cord. The two wire-limiting rods guide and limit the headphone cord during winding, preventing it from tangling.

[0009] In one embodiment, an elastic pad is fixedly connected to the inner wall of the adjustment frame, and the surface of the earphone cable is slidably connected to the inner wall of the elastic pad. The elastic pad seals the connection between the earphone cable and the adjustment frame, preventing dust from entering the adjustment frame.

[0010] In one embodiment, a smooth rod is slidably connected to the upper end of the inner wall of one of the socket panels.

[0011] In one embodiment, a second spring is fixedly connected to one end of the smooth rod, and the other end of the second spring is fixedly connected to one end of the socket disc. The interaction between the second spring and the smooth rod effectively restrains the headphone cord during winding, ensuring uniform force distribution and preventing damage to the headphone cord during winding.

[0012] In one embodiment, the limiting rod and the smoothing rod are both stainless steel components, and the positioning rod and the elastic pad are both rubber components.

[0013] Beneficial effects

[0014] 1. Loosen the headphone cord by moving the positioning rod away from the groove and rotating the winding rod to avoid pulling the headphone cord in the coiled state, thereby avoiding damage to the headphone cord and ensuring the service life of the headphone cord, thus ensuring the service life of the neckband headphones.

[0015] 2. Two limiting rods guide and limit the headphone cord during winding to prevent it from tangling. The second spring and the smooth rod work together to resist and limit the headphone cord during winding, ensuring that the headphone cord is evenly stressed during winding and preventing damage to the headphone cord.

[0028] The following is combined Figures 1-4 This invention describes an adjustable neckband-style headphone.

[0029] In one embodiment, an adjustable neckband headphone includes: a controller 100, with an adjustment frame 200 fixedly connected to one side of the controller 100; an adjustment mechanism 300, the adjustment mechanism 300 including a winding rod 301 rotatably connected to the inner wall of the adjustment frame 200, a headphone cord 302 wound around the surface of the winding rod 301, annularly distributed grooves 304 opening at the top of the adjustment frame 200, a positioning rod 303 slidably connected to the inner wall of the winding rod 301, the surface of the positioning rod 303 engaging with the inner wall of the groove 304, and two socket discs 306 fixedly connected to the inner wall of the adjustment frame 200, the surface of the winding rod 301 rotatably connected to the inner wall of the socket discs 306.

[0030] A collar is fixedly connected to one side of the controller 100. The collar is a flexible silicone component. The socket panel 306 is connected to the power cord of the controller 100.

[0031] It should be noted that the socket panel 306 and the winding rod 301 are connected by a multi-layered annular copper ring and a carbon brush in sliding contact, forming a rotating circuit interface. Current flows from the fixed power cord → socket panel 306 → winding rod 301 → headphone cord 302, achieving 360° unrestricted rotation for power supply.

[0032] When using the neckband headphones, rotate the retractor 301 to loosen the headphone cord 302. Then pull the headphone cord 302 to extend its length to hang over the user's ears. Hang the neckband headphones around the user's neck with the neckband behind the neck and the headphone cord 302 hanging naturally in front of the chest. Secure the earphones on the headphone cord 302 to the user's ears. Press and hold the multi-function button on the controller 100 for 5 seconds to light up the screen on the controller 100. Open the Bluetooth settings on your phone, search for the neckband headphone device name, and connect. You can then play music or audiobooks on your phone. To switch to the next song, simply use the buttons or screen on the controller 100.

[0033] like Figure 3 As shown, a first spring 305 is fixedly connected to the top of the positioning rod 303, and the top of the first spring 305 is fixedly connected to the inner top wall of the winding rod 301.

[0034] In this embodiment, the elastic force of the first spring 305 pushes the positioning rod 303 down and engages it in the corresponding groove 304, thereby positioning the winding rod 301.

[0035] like Figure 4 As shown, two wire limiting rods 307 are rotatably connected to the inner wall of the adjustment frame 200. The surface of the wire limiting rod 307 contacts the surface of the earphone cord 302. An elastic pad 308 is fixedly connected to the inner wall of the adjustment frame 200. The surface of the earphone cord 302 is slidably connected to the inner wall of the elastic pad 308.

[0036] like Figure 4 As shown, a smooth rod 310 is slidably connected to the upper end of the inner wall of one of the socket panels 306. A second spring 309 is fixedly connected to one end of the smooth rod 310, and the other end of the second spring 309 is fixedly connected to one end of the socket panel 306. The wire limiting rod 307 and the smooth rod 310 are both stainless steel components, while the positioning rod 303 and the elastic pad 308 are both rubber components. The first spring 305 and the second spring 309 are both rubber components.

[0037] In this embodiment, the elastic force of the second spring 309 pushes the smooth rod 310 to move and abut against the surface of the headphone cord 302, thereby limiting the winding of the headphone cord 302.

[0038] Working principle: Pull the positioning rod 303 away from the corresponding groove 304, rotate the winding rod 301, and then loosen the headphone cord 302. At this time, pull the headphone cord 302, and the moving headphone cord 302 passes between the two limiting rods 307, so that the length of the pulled-out headphone cord 302 can hang on the user's ear. The elastic force of the first spring 305 pushes the positioning rod 303 down and engages in the corresponding groove 304.

[0039] It should be noted that the controller 100, adjustment frame 200, winding rod 301, earphone cord 302, and socket panel 306 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the controller 100, winding rod 301, earphone cord 302, and socket panel 306 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
