Description

Technical Field

[0001] The utility model relates to the technical field of magnetically fixed bone conduction earphones, in particular to a magnetically fixed bone conduction earphone. Background Art

[0002] Bluetooth headsets are hands-free headsets that apply Bluetooth technology, allowing users to avoid the entanglement of annoying wires and make calls easily in various ways. Since the advent of Bluetooth headsets, they have been a good tool for mobile business people to improve efficiency. Sponge pads are installed on the bone support of Bluetooth headsets to prevent the bone support from direct contact and friction with the ear, which would prevent ear pain caused by wearing Bluetooth headsets for a long time.

[0003] After searching, a Chinese patent with publication number CN215445956U discloses a comfortable portable bone conduction Bluetooth headset, and its technical points are: the utility model discloses a comfortable portable bone conduction Bluetooth headset, including a headset body, a bone bracket and a connecting line, two bone brackets are symmetrically fixedly installed on the outside of the connecting line, and the headset body is fixedly installed at the bottom of the bone bracket, and the two ends of the connecting line pass through the bone bracket to be electrically connected with the headset body, and a support block is fixedly installed on the outer end of the bone bracket, and a spring 1 is fixedly installed inside the support block, and a moving block is fixedly installed on the other end of the spring 1, and the rear end of the moving block extends to the outside of the support block, and a U-shaped magnetic block is fixedly installed on the rear side of the bottom end of the support block. The utility model can not only drive the circular plate to move and adsorb and fit with the magnetic ring by pushing the T-shaped circular block to move, and then complete the fitting of the two bone brackets, but also can drive the U-shaped magnetic block to move by moving the moving block to clamp and fix the connecting line, and can also prevent the bone bracket from directly fitting with the ear through the design of the rubber jacket and sponge pad.

[0004] The above solution solves the problem that the bone conduction Bluetooth headset currently in use has certain defects, such as the lack of auxiliary storage function, which makes it inconvenient to fit the two bone supports together, and it is also inconvenient to clip the connection line together, which makes it inconvenient to store and carry the bone conduction Bluetooth headset. However, this device cannot be adjusted according to different groups of people. The head sizes of different groups of people are different. This device cannot adjust the size of the headset when in use, which easily causes some special groups to be unable to use the headset conveniently, resulting in limitations. To this end, we provide a magnetically fixed bone conduction headset to solve the above problems. Utility Model Content
