Abstract
Description
Technical Field
[0001] This utility model relates to the field of Bluetooth headset technology, specifically a noise-canceling Bluetooth headset. Background Technology
[0002] Noise-canceling Bluetooth headphones are widely popular because they can effectively isolate external noise, providing users with a quiet listening environment without the interference of wires. Their active noise cancellation function covers daily commutes and sports scenarios. Among them, neckband Bluetooth headphones have added elastic bands, which can prevent the earphone shells from falling directly to the ground even if they fall off the ears, thus enhancing their protective performance and making them more suitable for sports.
[0003] Some existing neckband-style Bluetooth headphones have electronic component boxes at both ends of the elastic band, which are connected to the two earphone shells by a wire. The wire is of a certain length and is easy to get tangled when not in use, which may lead to problems such as wire breakage and damage. When hanging up for storage, the wire may shake and cause the earphone shell to be bumped, resulting in damage to the internal components, making it inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to provide a noise-canceling Bluetooth headset to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides a noise-canceling Bluetooth headset, comprising:
[0006] The elastic band has two power supply component housings slidably connected to its outer wall. An earphone cable is fixedly connected to the outer wall of the power supply component housing. One end of the earphone cable is fixedly connected to an ear shell. Protective rings are fixedly connected to the top and bottom of the elastic band. Two retaining rings are symmetrically fixedly connected to the top of the upper protective ring. The earphone cable passes through the adjacent retaining rings.
[0007] An auxiliary module is disposed at both ends of the elastic band, and the auxiliary module is used to limit and protect the ear shell. Further, a connecting plate is fixedly connected to the outer wall of the power supply component housing, and a slider is fixedly connected to the inner wall of the connecting plate. A limiting groove is formed on the outer wall of the elastic band, and both sliders are slidably connected to the limiting groove.
[0008] Furthermore, one end of the slider is rotatably connected to a plurality of ball bearings.
[0009] Furthermore, an arc-shaped rod is fixedly connected through the interior of the slider, and a positioning block is fixedly connected to the inner wall of the limiting groove. The positioning block has slots on both sides, and the arc-shaped rod is movably engaged with the adjacent slot.
[0010] Furthermore, a magnet is fixedly connected to the inner wall of the card slot, and magnets are fixedly connected to both ends of the limiting groove.
[0011] Furthermore, the auxiliary module includes two limiting plates, which are fixedly connected to adjacent protective rings. A vertical plate is provided below the limiting plate, and a second slider is fixedly connected to the top of the vertical plate. The second slider is slidably connected to the bottom of the limiting plate. A shaft is rotatably connected to the top of the vertical plate, and a protective shell is fixedly connected to the outer wall of the shaft. A torsion spring is fixedly connected between the shaft and the second slider.
[0012] Furthermore, an elastic card is fixedly connected to the outer wall of the limiting plate, and the elastic card can be movably engaged with the adjacent vertical plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: after the headphones are used up, pull the power supply component shell to bring the two power supply component shells closer to the center of the elastic band until the arc rod is inserted into the slot for limiting. The attraction of the arc rod by the magnet inside the slot limits the two power supply component shells, effectively preventing the two headphone wires from getting tangled and preventing damage.
[0014] It also limits the position of the ear shell. Pulling the protective shell moves it out, and the protective shell rotates under the action of the torsion spring, wrapping and protecting the ear shell. This provides better protection when the device is accidentally dropped, extends the service life of the headphones, and makes them more convenient to use. Attached Figure Description

[0023] 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.
[0024] Please see Figure 1-7 This utility model provides a technical solution: a noise-canceling Bluetooth headset, comprising,
[0025] The elastic band 10 has two power supply component housings 11 slidably connected to its outer wall. The outer wall of the power supply component housing 11 is fixedly connected to an earphone cable 12. One end of the earphone cable 12 is fixedly connected to an ear shell 13. The top and bottom of the elastic band 10 are both fixedly connected to protective rings 101. Two retaining rings 103 are symmetrically fixedly connected to the top of the upper protective ring 101. The earphone cable 12 passes through the adjacent retaining rings 103.
[0026] The auxiliary module 15 is located at both ends of the elastic band 10. The auxiliary module 15 is used to limit and protect the ear shell 13.
[0027] In specific implementation, when the earphone is in use, the magnets 142 at both ends inside the limiting groove 102 attract the arc rod 114. The arc rod 114 is made of nickel-chromium alloy steel, thereby fixing the two power supply component shells 11 at both ends respectively. The elastic band 10 is put on the neck for auxiliary fixation, and the ear shell 13 can be used normally. The power supply component shell 11 is provided with electrical components for powering the ear shell 13 and transmitting signals.
[0028] After using the headphones, remove the elastic band 10 from the neck, wipe and dry the entire device, then pull the power supply component housing 11 so that the two power supply component housings 11 are close to the center of the elastic band 10 until the arc rod 114 is inserted into the slot 141 for limiting. The attraction of the arc rod 114 by the magnet 142 inside the slot 141 limits the two power supply component housings 11. During the process, the power supply component housing 11 pulls the headphone cable 12 through the retaining ring 103. Finally, the headphone cable 12 will not be taut to prevent damage to the headphone cable 12. Pull the protective shell 153 to remove it. The protective shell 153 rotates under the reset action of the torsion spring 156 and wraps and protects the ear shell 13.
[0029] See Figure 2-4 A connecting plate 111 is fixedly connected to the outer wall of the power supply component housing 11, and a slider 112 is fixedly connected to the inner wall of the connecting plate 111. A limiting groove 102 is opened on the outer wall of the elastic band 10, and both sliders 112 are slidably connected to the limiting groove 102.
[0030] One end of slider 112 is rotatably connected to multiple ball bearings 113.
[0031] In practice, the limiting groove 102 limits the slider 112, thereby limiting the sliding of the connecting plate 111 and the power supply component housing 11. This allows for adjustment of the position of the power supply component housing 11, which in turn helps to manage the headphone wires 12, preventing them from getting tangled and damaged. The ball bearing 113 helps to reduce friction between the slider 112 and the elastic band 10, making the overall movement of the power supply component housing 11 smoother and easier to control.
[0032] See Figure 4 An arc-shaped rod 114 is fixedly connected through the inside of the slider 112. A positioning block 14 is fixedly connected to the inner wall of the limiting groove 102. A slot 141 is provided on both sides of the positioning block 14. The arc-shaped rod 114 is movably engaged with the adjacent slot 141.
[0033] A magnet 142 is fixedly connected to the inner wall of the slot 141, and magnets 142 are fixedly connected to both ends of the limiting groove 102.
[0034] In practice, when storing the headphone wires 12, the two power supply component housings 11 are pulled and slid closer together until the arc-shaped rod 114 is inserted into the slot 141 for positioning. The magnet 142 is used to attract the arc-shaped rod 114 for auxiliary positioning, which can pull the two headphone wires 12 to a reasonable position for storage and protection, preventing the two headphone wires 12 from getting tangled together. At the same time, the position of the ear shell 13 is limited to prevent the headphone wires 12 from swinging and causing collision damage to the ear shell 13 when placed.
[0035] See Figure 5-7The auxiliary module 15 includes two limiting plates 151. The limiting plates 151 are fixedly connected to the adjacent protective rings 101. A vertical plate 152 is provided below the limiting plates 151. A slider 154 is fixedly connected to the top of the vertical plate 152. The slider 154 is slidably connected to the bottom of the limiting plates 151. A shaft 155 is rotatably connected to the top of the vertical plate 152. A protective shell 153 is fixedly connected to the outer wall of the shaft 155. A torsion spring 156 is fixedly connected between the shaft 155 and the slider 154.
[0036] An elastic card 157 is fixedly connected to the outer wall of the limiting plate 151, and the elastic card 157 can be movably engaged with the adjacent vertical plate 152.
[0037] In practice, after the headphone cable 12 is tidied up, the two ear shells 13 are located at both ends of the elastic band 10. To protect the headphone cable 12, the headphone cable 12 will not be taut, allowing the ear shells 13 to move slightly. However, if the device is dropped in this state, the ear shells 13 may be damaged by collision and impact. Therefore, after tidying up the headphone cable 12, the elastic card 157 is moved to contact the limit of the vertical plate 152 and the protective shell 153. At this time, the protective shell 153 can be pulled out horizontally. Then, under the reset action of the torsion spring 156, the protective shell 153 rotates 90 degrees, thereby wrapping the ear shells 13 inside for limit and protection. When the device is not in use, it can provide stable protection for the headphone cable 12 and the ear shells 13.
[0038] Working principle: When the earphone is in use, the magnets 142 at both ends of the limiting groove 102 attract the arc rod 114. The arc rod 114 is made of nickel-chromium alloy steel, thereby fixing the two power supply component shells 11 at both ends. The elastic band 10 is put on the neck for auxiliary fixation, and the ear shell 13 can be used normally. The power supply component shell 11 is equipped with electrical components for powering the ear shell 13 and transmitting signals.
[0039] After using the headphones, remove the elastic band 10 from the neck, wipe and dry the entire device, then pull the power supply component housing 11 so that the two power supply component housings 11 are close to the center of the elastic band 10 until the arc rod 114 is inserted into the slot 141 for limiting. The attraction of the arc rod 114 by the magnet 142 inside the slot 141 limits the two power supply component housings 11. During the process, the power supply component housing 11 pulls the headphone cable 12 through the retaining ring 103. Finally, the headphone cable 12 will not be taut to prevent damage to the headphone cable 12. Pull the protective shell 153 to remove it. The protective shell 153 rotates under the reset action of the torsion spring 156 and wraps and protects the ear shell 13.
