[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Please read Figure 1-5 As shown, the technical solution of this patent is as follows;

[0024] A replacement foam earphone structure includes an earphone telescopic bracket 1 and an earphone body 3. The earphone body 3 includes foam 32 and a speaker assembly 31. A magnetic fixing device is provided between the foam 32 and the speaker assembly 31, and the foam 32 can be replaced by the magnetic fixing device.

[0025] Furthermore, a metal sheet 6 is provided on one side of the foam 32. The metal sheet 6 is circular in shape, and several through holes 7 are provided on the outer wall of the circular shape.

[0026] Instructions are required; the metal sheet is made of stainless steel or iron, and such metal materials are attracted to magnets, allowing for a secure hold.

[0027] The speaker assembly 31 is provided with a plurality of magnetic posts 5, the positions of which are adapted to the through holes 7. The magnetic posts 5 are inserted into the through holes 7 for movable fixation, and then attracted by the magnetic posts.

[0028] The instruction manual is required; a silicone ring can also be set inside part of the through hole 7. When the magnetic column 5 is inserted, the magnetic column 5 squeezes the silicone ring, which can also achieve a tensioning effect and also have a magnetic attraction.

[0029] The speaker assembly 31 has a speaker 8 in the middle, and the foam 32 has a cavity 9 in the middle corresponding to the speaker 8.

[0030] The cavity 9 is conical in shape, tapering from large to small, through... Figure 5 It can be seen clearly.

[0031] A connecting wire 4 is provided on one side of the earphone body 3, and the connecting wire 4 is electrically connected to the electronic product.

[0032] A telescopic device 2 is provided between the telescopic bracket 1 and the earphone body 3, which allows the earphone body 3 to be lengthened.

[0033] It should be noted that the retractable device 2 is existing technology; therefore, this patent will not provide a detailed description of the existing technical solution.

[0034] Working principle:

[0035] First, align the through-hole of foam 32 with the position of magnetic post 31. The attraction of magnetic post 31 will cause the two objects to automatically attract each other. Then, to replace the old foam, simply pull it with a little force. Because foam 32 is circular, it is also arranged in a circular pattern with magnetic post 31. This way, the empty space of foam 32 can be attracted to magnetic post 31 regardless of the direction.
