Description

Technical Field

[0001] This utility model relates to the field of earmuff technology, specifically a modular magnetic earmuff quick-change structure. Background Technology

[0002] Earmuffs are ear protectors that cover the entire auricle. Noise-canceling earmuffs consist of two round shells connected by a bow frame. The shells are lined with sound-absorbing material and sealing gaskets. The overall shape resembles headphones and is suitable for noisy environments.

[0003] However, existing earcups are tightly connected to the headphone body during use and cannot be replaced separately. When the leather surface of the earcups is damaged due to prolonged use, sweat erosion, or environmental factors, users are often forced to replace the entire earcup assembly.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN222916166U discloses an earphone with easily replaceable parts, comprising an earphone body, a base, earcups, and filling material. The base is magnetically fixed to the earphone body. The base has inner and outer protrusions connected to its interior and edges. Inner and outer slots are correspondingly provided on the inner and outer sides of the inner and outer protrusions. Inner and outer retaining rings are connected to the interior and edges of the earcups. The upper part of the base is located between the inner and outer protrusions. The area between the earcups is provided with a lower limit groove, and the inside of the earcup is provided with an upper limit groove. The outer side of the inner retaining ring and the inner side of the outer retaining ring are respectively connected to an inner retaining ring and an outer retaining ring. The inner retaining ring and the outer retaining ring are respectively engaged inside the inner retaining groove and the outer retaining groove. Through the clever buckle design, namely the inner and outer retaining grooves and the inner and outer retaining rings, the earcup can be quickly and easily disassembled and replaced when the leather of the earcup is damaged, without having to replace the entire earcup. This preserves the plastic and sponge materials, saves resources to the maximum extent and avoids waste, and solves the problem of damaged earcups in a low-cost way.

[0005] The aforementioned device allows for the replacement of ear tips using inner and outer retaining rings during use. However, although the device can be disassembled, disassembly requires first removing the inner and outer retaining rings, which is extremely troublesome. Utility Model Content

[0006] The purpose of this invention is to provide a modular magnetic earmuff quick-change structure to solve the problem of cumbersome disassembly mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular magnetic earcup quick-change structure, comprising an earphone body, an earphone frame provided on the outer surface of the earphone body, a limiting block provided on the outer surface of the earphone frame, a connecting block provided on the inner side of the limiting block, and an adjusting component provided on the inner side of the earphone frame; an earcup provided on the outer surface of the earphone body, and an auxiliary assembly / disassembly mechanism provided on the inner side of the earcup.

[0008] Furthermore, the disassembly and assembly mechanism includes a connecting ring, which is disposed on the inner side of the earcup, and the outer surface of the connecting ring is provided with the headphone body.

[0009] Furthermore, the outer surface of the earmuff is provided with an ear sleeve, and the inner side of the ear sleeve is provided with a sponge.

[0010] Furthermore, the outer surface of the earcup is provided with a magnetic connector, and the inner side of the earcup is provided with a ring magnet.

[0011] Furthermore, an electromagnet is provided on the outer surface of the earcup, and a positioning bolt is provided on the inner side of the earcup.

[0012] Furthermore, the outer surface of the earcup is provided with a heat-conducting sheet, and the inner side of the earcup is provided with a ventilation groove.

[0013] Furthermore, the outer surface of the earmuff is provided with a metal heat-insulating component, the outer surface of the metal heat-insulating component is provided with an ear sleeve, and the inner side of the ear sleeve is provided with a sponge soft sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The earmuffs can be quickly disassembled and assembled through the disassembly and assembly mechanism. Users can easily replace the earmuffs without complicated operations, which greatly improves the convenience of use. By setting electromagnets and positioning bolts, the stability and accuracy of the earmuffs during disassembly and assembly can be further ensured.

[0016] (2) The electromagnet is magnetically controlled by a switch. When the electromagnet is energized, it generates magnetism and attracts the ring magnet, so that the earcups are tightly connected to the headphone body. When the electromagnet is de-energized, it loses its magnetism and the earcups can be easily removed from the headphone body for quick replacement. The positioning bolts can play a positioning role during disassembly and assembly, ensuring that the earcups can be accurately installed in the designated position on the headphone body.

[0017] (3) By setting heat-conducting plates and ventilation slots, the heat dissipation performance of the earcups is improved, making it more comfortable for users to wear headphones for a long time. The heat-conducting plates can quickly dissipate the heat inside the earcups, while the ventilation slots can allow air circulation and further accelerate the heat dissipation speed.

[0018] (4) The use of metal insulation and sponge soft cover can improve the heat preservation performance and wearing comfort of the earmuff. The metal insulation can effectively block the invasion of cold air from the outside to the ear, while the sponge soft cover can provide a soft touch and reduce the friction and pressure between the ear and the earmuff.

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a modular magnetic earcup quick-change structure, including an earphone body 1, an earphone frame 2 is provided on the outer surface of the earphone body 1, a limiting block 3 is provided on the outer surface of the earphone frame 2, a connecting block 4 is provided on the inner side of the limiting block 3, and an adjusting component 5 is provided on the inner side of the earphone frame 2; an earcup 6 is provided on the outer surface of the earphone body 1, and an auxiliary assembly and disassembly mechanism is provided on the inner side of the earcup 6.

[0028] The earcups 6 and the headphone body 1 are magnetically attached, allowing for quick assembly and disassembly. This facilitates easy replacement of the earcups 6. Specifically, the headphone body 1 has a corresponding ring magnet 10 that engages with the magnetic connector 9. When the earcups 6 need to be installed on the headphone body 1, they attract each other magnetically and are fixed together, enabling quick installation. To enhance the comfort and warmth of the earcups 6, the outer surface is covered with ear tips 7. The inner side of the ear tips 7 is lined with soft foam. The foam has good elasticity and breathability, providing comfortable support and protection for the user's ears. The ear tips 7 and the foam further improve the sound insulation of the earcups 6, reducing external noise interference.

[0029] Example 2: Based on Example 1, please refer to... Figure 2 - Figure 4 The earcup 6 was also disclosed, and its specific structure is as follows: the disassembly and assembly mechanism includes a connecting ring 8, which is set on the inner side of the earcup 6. The outer surface of the connecting ring 8 is provided with the headphone body 1. The outer surface of the earcup 6 is provided with the ear sleeve 7. The inner side of the ear sleeve 7 is provided with a sponge. The outer surface of the earcup 6 is provided with a magnetic connector 9. The inner side of the earcup 6 is provided with a ring magnet 10.

[0030] The magnetic connector 9 and the ring magnet 10 allow the earcups 6 to easily attach to the headphone body 1. Figure 2 It is known that an electromagnet 13 is also provided on the outer surface of the earcup 6. The electromagnet 13 works in conjunction with the positioning bolt 11 to further secure the connection between the earcup 6 and the headphone body 1, preventing the earcup 6 from falling off during vigorous exercise or accidental collision, ensuring the safety and stability of the user during use. The power supply of the electromagnet 13 can be switched on and off by the switch. When it is necessary to remove the earcup 6 for cleaning or replacement, the power supply of the electromagnet 13 can be turned off by manually pushing the switch, so that it loses its magnetism, and the earcup 6 can be removed.

[0031] Example 3: Based on Example 1, please refer to... Figure 3 - Figure 6 The electromagnet 13 was also disclosed, and its specific structure is as follows: an electromagnet 13 is provided on the outer surface of the earcup 6, a positioning bolt 11 is provided on the inner side of the earcup 6, a heat-conducting plate 12 is provided on the outer surface of the earcup 6, a ventilation groove 14 is provided on the inner side of the earcup 6, a metal heat-insulating component 15 is provided on the outer surface of the metal heat-insulating component 15, an ear sleeve 7 is provided on the outer surface of the ear sleeve 7, and a sponge soft sleeve 16 is provided on the inner side of the ear sleeve 7.

[0032] The heat-conducting plate 12 quickly dissipates heat from inside the earcups 6, preventing discomfort during prolonged wear. The ventilation slot 14 increases airflow within the earcups 6, further enhancing user comfort. Figure 6 It can be seen that the metal heat insulation component 15 can maintain the temperature inside the earcup 6 in cold environments and prevent heat loss too quickly, while the sponge soft cover 16 can further increase the softness and comfort of the earcup 6, providing users with a better wearing experience.
