Description

Technical Field

[0001] The invention belongs to the technical field of earphones, and in particular relates to a Bluetooth earphone. Background Art

[0002] ‌‌Bluetooth headset is a wireless communication product. Bluetooth technology was originally developed by six manufacturers including Ericsson, Nokia, IBM, Intel, Toshiba, and CEIEC. As a short-range wireless transmission communication interface, Bluetooth operates on the 2.4GHz frequency band and supports one-to-many data transmission and voice communication. Bluetooth headsets apply this Bluetooth technology to hands-free headsets, allowing users to avoid the entanglement of wires and talk freely. It is widely used in communication with mobile phones, computers and other devices with Bluetooth functions. It is a good tool for mobile business people to improve efficiency. Users can use Bluetooth headsets for voice calls, music playback and other operations and enjoy the convenience brought by wireless.

[0003] Among Bluetooth headsets, head-mounted Bluetooth headsets are less harmful to the eardrum because the sound is transmitted through the head-mounted design instead of directly entering the ear canal, so they are more friendly to the ears. In addition, head-mounted Bluetooth headsets usually have better wrapping and better passive noise reduction, and can obtain fuller sound effects at lower volumes. However, wearing head-mounted Bluetooth headsets for a long time or using them frequently will cause the foam to wear, which will affect the sealing and comfort of the headset. At the same time, the wear of the foam may also lead to a decrease in sound quality, because the foam is the main isolation layer between the headset and the ear, and the wear will affect the sound. In order to improve the transmission and isolation effects, the foam on the ears of head-mounted Bluetooth headsets can be removed and replaced by buckles. However, in actual use, the cushion at the headband of the headset is more susceptible to compression and wear. This area is located on the inner side of the headband of the headset. In order to hide the screws used to open the headband, the cushion is usually glued directly to the inner side of the headband, and requires professional tools such as blades to cut it open for replacement. At the same time, the headband and the headset are fixed with screws, which makes the operation process cumbersome when the cushion at the headband is damaged or the headset is damaged and needs repair, which greatly reduces the convenience of using the Bluetooth headset.

[0004] Therefore, it is particularly important to design a Bluetooth headset to solve the above-mentioned defects. Summary of the invention

[0021] This specific implementation is a Bluetooth headset, and its structural diagram is as follows Figure 1-11 As shown, the Bluetooth headset includes a head beam frame 1, an inner frame 2 is clamped on the inner side of the head beam frame 1, a soft pad 3 is fixedly connected to the inner side of the inner frame 2, a fixing box 4 is fixedly installed inside the head beam frame 1, the left and right ends of the head beam frame 1 are rotatably connected with connecting frames 5, the tops of the two groups of connecting frames 5 are fixedly connected with connecting heads 6, the front and rear sides of the two groups of connecting heads 6 are rotatably connected to the head beam frame 1 through quick-release parts 7, the inner sides of the bottom ends of the two groups of connecting frames 5 are rotatably connected with earphone covers 8, the inner frame 2 is fixed to the inner side of the head beam frame 1 through the fixing box 4, the soft pad 3 on the inner side of the inner frame 2 can improve the comfort of the top of the head when the Bluetooth headset is worn, and when the soft pad 3 is damaged, the fixing of the inner frame 2 can be quickly released through the fixing box 4, thereby facilitating the disassembly and replacement of the soft pad 3, and the connecting head 6 is fixedly connected to the head beam frame 1 through the fixing box 4. The quick-release part 7 is rotatably connected to the head beam frame 1, so that the connecting frame 5 can swing toward the inside of the head beam frame 1, which can not only automatically adjust to fit the user's head when the Bluetooth headset is worn, but also when the Bluetooth headset is not in use, the two sets of connecting heads 6 can be swung toward the inside of the head beam frame 1 for folding, thereby reducing the size of the Bluetooth headset for easy carrying. At the same time, the earphone cover 8 can be rotated on the inside of the connecting frame 5, so that the Bluetooth headset can be automatically adjusted to further fit the user's head when worn, which can not only effectively ensure the wearing comfort, but also the sound effect after wearing. When the earphone cover 8 is damaged, the quick-release part 7 can also be used to quickly separate the connecting head 6 from the head beam frame 1 to perform a separate repair of the earphone cover 8, thereby improving the convenience of using the Bluetooth headset.

[0022] First, in this embodiment, the specific structure of the fixing box 4 is as follows: Two groups of fixed plugs 401 are symmetrically and slidably connected inside the fixed box 4, and fixed holes 402 are opened at positions corresponding to the fixed plugs 401 inside the inner frame 2. A first spring 403 is movably installed inside the fixed box 4 and between the two groups of fixed plugs 401. The opposite ends of the two groups of fixed plugs 401 are fixedly connected with an operating handle 404. When the Bluetooth headset is used, after the inner frame 2 is inserted into the inner side of the head beam frame 1, the fixed box 4 is inserted into the inner side of the top of the inner frame 2. Under the pressure of the first spring 403, the two The two groups of fixing pins 401 are pushed out of the interior of the fixing box 4, so that the two groups of fixing pins 401 are continuously inserted into the fixing holes 402 in the inner frame 2, thereby firmly fixing the inner frame 2. After the cushion 3 on the inner frame 2 is damaged, it is only necessary to pinch the two groups of operating handles 404 to compress the first spring 403 inside the fixing box 4, and at the same time drive the two groups of fixing pins 401 to retract into the interior of the fixing box 4, thereby quickly releasing the fixation of the inner frame 2 and disassembling and replacing the cushion 3, which greatly improves the convenience of using the Bluetooth headset.

[0023] Then, a slot 405 is opened at the position of the top of the inner frame 2 corresponding to the fixing box 4, and docking slots 406 are opened at the left and right ends of the top of the inner frame 2. An operating slot 407 is opened at the position of the top of the head beam frame 1 corresponding to the operating handle 404. When replacing a new soft pad 3, first pinch the two sets of operating handles 404 to retract the fixed pin 401 into the interior of the fixing box 4, and then dock the left and right ends of the top of the inner frame 2 with the head beam frame 1 through the docking slot 406. At the same time, the fixing box 4 is automatically inserted into the interior of the slot 405. Finally, release the operating handle 404 to fix the inner frame 2, so that the soft pad 3 can be quickly disassembled and replaced, further improving the convenience of using the Bluetooth headset.

[0024] Furthermore, a protective plate 408 is fixedly connected to the top of the fixed box 4 and between the two groups of operating handles 404. The two groups of operating handles 404 are slidably connected to the protective plate 408 through a slide groove 409. The operating handles 404 are slidably connected to the protective plate 408 through the slide groove 409, so that the operating handles 404 can slide and drive the fixed plug 401 to move. The protective plate 408 is used to protect the top of the fixed box 4 to prevent external impurities from entering and affecting its normal use.

[0025] Among them, movable grooves 601 are opened at positions corresponding to the connecting heads 6 at both ends of the head beam frame 1, and wiring holes 602 are opened inside the two groups of connecting heads 6. After the connecting heads 6 are inserted into the inner side of the movable grooves 601, the connecting heads 6 and the head beam frame 1 are connected through the quick release parts 7, so that the connecting frame 5 can swing toward the inner side of the head beam frame 1, which can not only automatically adjust to fit the user's head when the Bluetooth headset is worn, but also when the Bluetooth headset is not in use, the two groups of connecting heads 6 are swung toward the inner side of the head beam frame 1 for folding, thereby greatly reducing the size of the Bluetooth headset for easy carrying.

[0026] Furthermore, the quick-release part 7 includes an insert tube 701 which is inserted into the two ends of the head beam frame 1 and is located at the front and rear sides of the connecting head 6. The interior of the insert tube 701 is rotatably connected to a rotating shaft 702, and the outer side of the rotating shaft 702 is threadedly connected to a movable sleeve 703. The outer end of the rotating shaft 702 close to the connecting head 6 is rotatably connected to an extrusion sleeve 704. A second spring 705 is sleeved on the outer side of the rotating shaft 702 and located between the extrusion sleeve 704 and the movable sleeve 703. A card ball 706 is movably installed at one end of the insert tube 701 located inside the connecting head 6 and on the outer side of the extrusion sleeve 704. After the connecting head 6 is inserted into the interior of the movable groove 601, the insert tube 701 is inserted into the interior of the head beam frame 1, and then the rotating shaft 702 is rotated to drive the movable sleeve 703 to move. Move, push the second spring 705 through the movable sleeve 703, and the second spring 705 will push the extrusion sleeve 704 to slide on the outside of the rotating shaft 702 until the extrusion sleeve 704 squeezes the card ball 706 inside the plug sleeve 701 out from the inside of the plug sleeve 701, thereby locking the plug sleeve 701 through the card ball 706, connecting the connecting head 6 and the head beam frame 1, so that the connecting head 6 can rotate, and when the earphone cover 8 is damaged, the reversing rotating shaft 702 can quickly release the lock of the plug sleeve 701, and then the plug sleeve 701 can be taken out from the inside of the head beam frame 1 to separate the earphone cover 8 from the head beam frame 1, thereby facilitating the separate disassembly and maintenance of the earphone cover 8, further improving the convenience of using the Bluetooth headset.

[0027] Furthermore, one end of the insert tube 701 located on the outside of the head beam frame 1 is fixedly connected with a positioning head 707, and a positioning groove 708 is opened at a position on the outside of the head beam frame 1 corresponding to the positioning head 707. After the insert tube 701 is inserted into the interior of the head beam frame 1, the inner side of the positioning head 707 is inserted into the interior of the positioning groove 708, and the end of the insert tube 701 located on the outside of the head beam frame 1 is positioned by the positioning head 707, thereby avoiding the insert tube 701 from rotating together with the rotating shaft 702.

[0028] Furthermore, a screw groove 709 is provided at one end of the rotating shaft 702 located on the outside of the head beam frame 1, and the interior of the movable sleeve 703 is threadedly connected to the rotating shaft 702 through a threaded sleeve 710. The rotating shaft 702 is rotated by turning the screw groove 709, and the movable sleeve 703 is driven to move on the outside of the rotating shaft 702 by rotating the rotating shaft 702 forwards and reversely and under the connection of the threaded sleeve 710. When it is particularly noted here, the shape of the screw groove 709 is set according to other screws of the Bluetooth headset, so that the Bluetooth headset can be operated by the same screwdriver during assembly and maintenance.

[0029] Secondly, the outer side of the movable sleeve 703 is symmetrically connected with positioning blocks 711, and the two groups of positioning blocks 711 are slidably connected to the insertion tube 701 through the limiting groove 712. The two ends of the second spring 705 are fixedly connected to the movable sleeve 703 and the extrusion sleeve 704 respectively. A card groove 713 adapted for the card ball 706 is opened inside the connector 6. When the rotating shaft 702 is rotated, the positioning block 711 slides linearly on the inner side of the limiting groove 712, thereby preventing the movable sleeve 703 from rotating together when the rotating shaft 702 rotates, so that the movable sleeve 703 can only move linearly, thereby pushing the second spring 705 to move on the outer side of the rotating shaft 702, and finally pushing the extrusion sleeve 704 to push the card ball 706 out of the inner side of the insertion tube 701 The insert tube 701 is locked, and the shaft 702 continues to rotate after the extrusion sleeve 704 pushes out the card ball 706 until the second spring 705 is compressed to the maximum extent, so that the second spring 705 can continue to act on the extrusion sleeve 704, ensuring the locking effect of the card ball 706 on the insert tube 701. When releasing the lock of the insert tube 701, the shaft 702 is reversed and the movable sleeve 703 is moved in the opposite direction, and then the extrusion sleeve 704 is pulled to move by the second spring 705, and finally the earphone cover 8 is shaken to make the card ball 706 retract into the inside of the insert tube 701, so that the insert tube 701 can be poured out from the inside of the head beam frame 1 to release the connection with the connecting head 6, which is convenient for the earphone cover 8 to be disassembled and repaired separately.

[0030] Furthermore, earphone foam 801 is clamped on the opposite side of the two groups of earphone covers 8, and heat dissipation groove 802 is opened on the opposite side of the two groups of earphone covers 8. The inner sides of the two groups of heat dissipation grooves 802 are fixedly connected with ventilation nets 803. The ventilation net 803 is located on one side of the interior of the earphone cover 8 and is fixedly installed with a first dustproof net 804. The interior of the ventilation net 803 is fixedly connected with multiple groups of reinforcing ribs 805. After the Bluetooth headset is worn, the earphone foam 801 covers the outer side of the user's ear. When the Bluetooth headset is used in summer, as the Bluetooth headset is continuously used, the heat inside the earphone cover 8 is difficult to discharge, which makes the user feel stuffy. The heat dissipation groove 802 can quickly discharge the heat inside the earphone cover 8, thereby improving the wearing comfort of the Bluetooth headset. At the same time, the heat dissipation groove 802 is protected and strengthened by the ventilation net 803 and the reinforcing ribs 805 to prevent it from being easily damaged by external forces. Moreover, the first dustproof net 804 on one side of the interior of the earphone cover 8 of the ventilation net 803 can also prevent external impurities from entering the interior of the earphone cover 8 during ventilation and heat dissipation.

[0031] Finally, the inner side of the earphone foam 801 is fixedly connected with a second dustproof net 806, and the inner side of the earphone foam 801 is snapped with the earphone cover 8 through multiple sets of buckles 807. When the earphone foam 801 is in use, it and the earphone cover 8 are directly protected by the second dustproof net 806 to prevent impurities from entering the interior of the earphone cover 8 and causing impact. The earphone foam 801 is snapped with the earphone cover 8 through multiple sets of buckles 807 on the inside, so that it is convenient to replace it when it is damaged.

[0032] When using the device of the present technical solution, first insert the inner frame 2 into the inner side of the head beam frame 1, insert the fixing box 4 into the inner side of the top of the inner frame 2, and under the pressure of the first spring 403, push the two groups of fixing pins 401 out of the inside of the fixing box 4, so that the two groups of fixing pins 401 are continuously inserted into the fixing holes 402 in the inner frame 2, thereby firmly fixing the inner frame 2. After the cushion 3 on the inner frame 2 is damaged, it is only necessary to pinch the two groups of operating handles 404 to compress the first spring 403 inside the fixing box 4, and at the same time drive the two groups of fixing pins 401 to retract into the fixing box 4, thereby quickly releasing the fixation of the inner frame 2 and disassembling and replacing the cushion 3. The connecting head 6 is rotatably connected to the head beam frame 1 through the quick-release part 7, so that the connecting frame 5 can be moved to the inner side of the head beam frame 1 The swing can not only automatically adjust the Bluetooth headset to fit the user's head when the Bluetooth headset is worn, but also, when the Bluetooth headset is not in use, the two sets of connectors 6 can be swung toward the inside of the headband frame 1 to be folded, thereby reducing the size of the Bluetooth headset for easy carrying. At the same time, the earphone cover 8 can be rotated on the inside of the connecting frame 5, so that the Bluetooth headset can automatically adjust to further fit the user's head when worn, which can not only effectively ensure the wearing comfort, but also ensure the sound effect after wearing. When the earphone cover 8 is damaged, the quick release part 7 can also quickly separate the connector 6 and the headband frame 1 to perform a separate repair of the earphone cover 8. The whole operation process is simple and convenient. Compared with the existing Bluetooth headset, the present invention can improve the convenience of use of the Bluetooth headset through design.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
