Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, specifically a retractable neckband-style multi-functional Bluetooth headset. Background Technology

[0002] Bluetooth headphones are portable headphones that enable wireless audio transmission via Bluetooth technology. They can be paired with devices without the need for physical cables. There are many types of Bluetooth headphones. Neckband Bluetooth headphones integrate the cable with the neckband, providing a secure fit, making them suitable for sports and less likely to be lost.

[0003] Currently, Bluetooth headphones still have some shortcomings, such as the fact that they need to be hung on the ears, which can cause pressure on the ears after a while.

[0004] To overcome the problem of earphones causing pressure on the ears, a Chinese patent (publication number: CN215379197U) discloses a portable Bluetooth headset. This device distributes ear pressure to the wearer's head, reducing pressure and improving comfort. It includes two Bluetooth headsets, two hanging brackets, a pressure-reducing strap, a cable management box, a swivel, a gear, and an elastic baffle. The two Bluetooth headsets are mounted inside the two hanging brackets, which are connected by the pressure-reducing strap. The cable management box has a cable management cavity inside, with through holes at both the top and bottom. The pressure-reducing strap extends through the two through holes into the cable management cavity and wraps around the swivel. The swivel is rotatably mounted at the rear end of the cable management cavity. A gear is mounted at the front of the swivel, with the front end of the swivel extending through the front of the cable management box to the front side of the box. An elastic baffle is mounted at the top of the cable management cavity and engages with the gear.

[0005] However, the Bluetooth headphones currently in use still have some shortcomings. In the aforementioned document, the Bluetooth headphone cable is wound around the pressure-reducing strap through a cable management box to improve the comfort of wearing the headphones. However, this component is integrated with the headphones, and it will affect the comfort of wearing them when hanging around the neck. In addition, the twisting winding method is relatively inefficient, affecting the efficiency of operating the headphones. Therefore, the existing structure needs to be improved.

[0029] 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.

[0030] Example 1, such as Figures 1-7 The present invention provides the following technical solution to address the problem of long Bluetooth headset cables being inconvenient to carry: A compression mechanism is disclosed, comprising a hanging ring 1, with a headset cable 2 connected to the side of the hanging ring 1, and a headset body 3 connected to the end of the headset cable 2. Two Velcro rolls 101 are movably connected to the surface of the hanging ring 1, and the Velcro rolls 101 are wound around the surface of the hanging ring 1. A winding block 102 and a winding block 103 are respectively connected to the sides of the two Velcro rolls 101. A fixing block 104 is fixed to the sides of the winding blocks 102 and 103 away from the hanging ring 1. A compression mechanism for positioning the headset cable 2 is provided inside the fixing block 104. The compression mechanism includes a sliding rod 105, which slides through the fixing block 104. Two sets of sliding rods 105 are symmetrically connected vertically about the fixing block 104. A pressing plate 106 is rotatably connected to the end of the sliding rod 105. A toothed block 107 is connected to the inner side of the sliding rod 105. A gear 108 is meshed between the two sliding rods 105. The gear 108 rotates inside the fixed block 104. A ratchet 109 is fixed to the side of the gear 108. The ratchet 109 rotates inside the twist groove 110. The twist groove 110 is opened inside the fixed block 104. A rotating groove 111 is opened on the side of the twist groove 110. A rotating block 112 is rotatably connected inside the rotating groove 111. A torsion spring is connected between the rotating block 112 and the rotating groove 111. A rotating block 113 is fixed to the end of the rotating block 112. The rotating block 113 rotates inside the twist groove 110 and is attached to the side of the ratchet 109. A knob 114 is fixed to the side of the rotating block 113 away from the rotating block 112. The knob 114 rotates through the rotating groove 111.

[0031] When using the headphones, the earring loop 1 needs to be hung around the neck, and then the headphone body 3 is inserted into the ear. When the headphones need to be put away, moving the headphone body 3 will move the headphone cable 2. When the headphone cable 2 moves to the side of the winding block 102, it can be wound. The headphone cable 2 will be slowly wound inside the tooth groove of the winding block 102. After the headphone cable 2 is wound, the pressing plate 106 is rotated. When the pressing plate 106 rotates, it can be rotated by the sliding rod 105. When the pressing plate 106 rotates to the upper and lower surfaces of the winding block 102, it can be located on the surface of the headphone cable 2. Then, pressing the pressing plate 106 will drive the sliding rod 105 to slide inside the fixed block 104. When the sliding rod 105 slides, it can drive the toothed block 107 to move. The two toothed blocks 107 will move relative to each other. When the toothed blocks 107 move, they can drive the... Gear 108 meshes and rotates. When gear 108 meshes and rotates, it can rotate inside fixed block 104. When gear 108 rotates, it can drive ratchet 109 to rotate. When ratchet 109 rotates, the inclined surface of the meshing teeth can squeeze rotating block 113. When rotating block 113 is squeezed, it can drive rotating block 112 to rotate. When rotating block 112 rotates, it can rotate through rotating groove 111. When rotating block 112 rotates, it can tighten torsion spring. After rotating block 113 rotates out of the inner side of ratchet 109, sliding rod 105 can slide relative to fixed block 104. When sliding rod 105 drives squeezing plate 106 to slide to the side of headphone wire 2, it can squeeze and position, which can prevent the wound headphone wire 2 from becoming loose and unstable. The removal realizes the Bluetooth headphone wire winding function, making the Bluetooth headphone convenient to carry.

[0032] Example 2, as follows Figure 3 and Figure 8 The present invention provides the following technical solution to address the problem that the Bluetooth earphone hanging ring 1 has a large support range, making it inconvenient to carry the earphone. Based on embodiment one, a locking mechanism is disclosed: a locking groove 115 is symmetrically opened on the side of the winding block 102 near the Velcro roll 101. The locking groove 115 is provided with a locking mechanism to reduce the area occupied by the earphone. The locking mechanism includes a rotating groove 116, which is symmetrically opened on the top of the winding block 103. A friction pad 117 is symmetrically connected to the inner side of the rotating groove 116. A locking block 118 is rotatably connected inside the rotating groove 116. The locking block 118 and the locking groove 115 are locked together.

[0033] After the Bluetooth earphone's cable is wound up by the compression mechanism, the hanging loop 1 can be bent. The first winding block 102 and the second winding block 103 on the side of the hanging loop 1 are brought closer together, and the locking block 118 is rotated. The locking block 118 can rotate through the rotating groove 116. Simultaneously, the rotation of the locking block 118 compresses the friction pad 117. When the friction pad 117 is compressed, it deforms due to its material. After deformation, the rotating groove 116 can rotate out of the winding block 103. When the first winding block 102 and the second winding block 103 approach each other, they respectively drive the locking groove 115 and the locking block 118 to move. When the locking block 118 moves to the side of the locking groove 115, it can be inserted. When the locking block 118 is inserted, the inclined surface can squeeze the side of the locking groove 115. When the locking block 118 is squeezed, it can deform through its own rubber material. When the locking block 118 is deformed, it can be inserted into the locking groove 115 for reset. When the locking block 118 is reset, it can engage and position with the locking groove 115. After the locking block 118 is positioned, it can drive the winding block 102 and the winding block 2 103 to be positioned, thereby driving the hanging ring 1 to bend and position, further reducing the volume of the hanging ring 1 and improving the portability of the Bluetooth headset.

[0034] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
