[0002] With the development of society, people's requirements for technology are getting higher and higher. Bluetooth headsets are a kind of listening device that is convenient for people to use with them, and their application is becoming more and more extensive. However, long-term use of in-ear headphones can easily cause damage to the ears. You need to pay attention to the volume and usage time when using them. It is also easy to lose hearing the sounds on the road when wearing headphones while walking or riding. For this reason, clip-on Bluetooth headsets came into being, but the same problem applies. Clip-on headphones can cause discomfort and even redness and itching of the ears if worn for a long time.

[0003] However, there are some problems with the prior art: since the clip-on earphones need to be clipped on the ears, the weight of the earphones is borne entirely by the ears, so the ears will become red and itchy after wearing them for a long time.

DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a fitted earphone cover, comprising a mounting groove 1 provided on the ear clip, connecting holes 11 provided on both sides of the mounting groove 1, an earphone cover 12 provided in the mounting groove 1, a plunger 13 inserted in the mounting groove 1, the plunger 13 is used to close the mounting groove 1, an inner cavity 14 is provided on the plunger 13, a hollow area is formed on the plunger 13, the hollow area is located in the middle of the inner cavity 14, a pressure piece 15 is inserted in the inner cavity 14, and the pressure piece 15 is in contact with the earphone cover 12.

[0022] Furthermore, the earphone sleeve 12 is installed inside the mounting groove 1, the plunger 13 is buckled on the mounting groove 1 to close it, and the pressure piece 15 is installed on the plunger 13 to adjustably press the airbag 2 in the earphone sleeve 12 to ventilate and expand the ring 22. The ring 22 fits according to the shape of the ear during the expansion process, and the inflation amount can be adjusted according to personal needs to obtain the best comfort and fit;

[0023] Furthermore, the inner cavity 14 of the plunger 13 is a hollow area for installing the pressure piece 15 , and a structure for limiting the stroke of the pressure piece 15 is provided on the plunger 13 to prevent the pressure piece 15 from being pressed too deeply or detaching from the plunger 13 .

[0024] Specifically, the earphone cover 12 includes an airbag 2, which is fixedly installed in the installation groove 1. Air inlet pipes 21 are arranged on both sides of the airbag 2. The air inlet pipes 21 are arranged corresponding to the connecting holes 11. A ring 22 is arranged on the output end of the air inlet pipe 21. The ring 22 is an inflatable part. The ring 22 is installed on the outside of the ear clip for fitting the ear.

[0025] Furthermore, the earphone cover 12 is composed of an airbag 2, an air inlet pipe 21 and a ring 22, and the airbag 2, the air inlet pipe 21 and the ring 22 are all sealed to prevent air leakage. The pressure of the ring 22 is greater than that of the airbag 2. This ensures that when the pressure of the airbag 2 is released, the ring 22 will discharge the internal gas through the air inlet pipe 21 into the airbag 2 through the pressure, so that the pressure block 31 is forced to rebound.

[0026] Specifically, the pressure member 15 includes a pressure plate 3 and a button 4. A pressure block 31 is fixedly connected to the pressure plate 3. The pressure plate 3 contacts the plunger 13. The pressure block 31 is plugged into the plunger 13. A limit pin 34 is provided between the pressure block 31 and the plunger 13 for adjusting the pressing degree of the pressure block 31.

[0027] Specifically, an adjustment hole 32 is provided on the plunger 13, a limit hole 33 is provided on the pressure block 31, a limit pin 34 is slidably connected inside the limit hole 33, the limit pin 34 is plugged into the adjustment hole 32, a spring 35 is provided inside the limit hole 33, one end of the spring 35 is fixedly connected to the limit hole 33, and the other end of the spring 35 is fixedly connected to the limit pin 34.

[0028] Furthermore, the limit pin 34, the adjustment hole 32 and the limit hole 33 are all arranged correspondingly, and the limit hole 33 is aligned with the adjustment hole 32. When the limit pin 34 is separated from the adjustment hole 32 and retracts into the limit hole 33, the spring 35 is compressed to release the limit pin 34. The spring 35 uses the elastic force to automatically insert the limit pin 34 into the adjustment hole 32 to achieve fixation.

[0029] Specifically, there are multiple adjusting holes 32 , which are symmetrically distributed on both sides of the plunger 13 , and the adjusting holes 32 and the limiting holes 33 are correspondingly arranged.

[0030] Furthermore, the number of the adjustment holes 32 can be multiple groups, and the adjustment holes 32 are symmetrically distributed to adapt to different adjustment degrees.

[0031] Specifically, the button 4 is plugged into the pressure block 31, a sliding hole 41 is opened on the pressure block 31, a guide rod 42 is fixedly connected to the button 4, the guide rod 42 is plugged into the sliding hole 41, a connecting through hole is provided between the sliding hole 41 and the limiting hole 33, a pair of lifting ears 43 are provided on the outer side of the guide rod 42, and a metal wire 44 is provided between the lifting ears 43 and the limiting pin 34.

[0032] Working principle: When in use, first press the button 4, the button 4 drives the guide rod 42 to slide downward inside the sliding hole 41, and at the same time, the ear 43 on the guide rod 42 drives the limit pin 34 to slide through the metal wire 44, and the limit pin 34 is separated from the adjustment hole 32 by the hand traction force, slides into the limit hole 33, and compresses the spring 35. At this time, force is applied to press the pressure block 31, and the pressure block 31 drives the pressure plate 3 to slide inside the installation groove 1, and the pressure plate 3 presses the airbag 2. The airbag 2 shrinks under the force and discharges the internal gas into the ring 22 through the intake pipe 21. The ring 22 is inflated and expanded. By continuously pressing the pressure block 31, the ring 22 is inflated to fit the ear until it is in a suitable position, and the button 4 is released. The limit pin 34 rebounds under the elastic force of the spring 35 and is inserted into the adjustment hole 32 to achieve fixation, so that the ring 22 is in a fixed and expanded state.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
