In this embodiment, preferably, the locking and fixing component includes a clamping head 1044 arranged at the end of the pull rod 1042, and the edge of the rotating knob 104 is located at the adjustment groove 1046 at the bottom end of the speaker seat 102, and a clamping hole 1045 is opened at the inner edge of the adjustment groove 1046. The end of the clamping head 1044 is consistent with the internal structure of the clamping hole 1045, so that after the rotating knob 104 and the rotating shaft 1034 are rotated to a certain position, the clamping head 1044 is locked in the inside of the clamping hole 1045 to lock the rotating knob 104 and the rotating shaft 1034 together, so as to facilitate the fixed protection of the folding protective curtain 1030, otherwise the folding protective curtain 1030 is opened for fixed installation and use.

[0035] The working principle and use process of the utility model are as follows: the earphone with built-in protection structure is placed before use for protection after use. First, the finger pulls the pull rod 1042 to disengage the clamp head 1044 from the inside of the clamp hole 1045, pulls the pull rod 1042 to open and rotates the rotating knob 104 to drive the rotating shaft 1034 to rotate. The rotation of the rotating shaft 1034 drives the torsion gear 1 1035 to engage with the outer surface of the torsion gear 2 1036 to rotate. When the torsion gear 2 1036 rotates, it drives the connecting shaft 1037 and the rotating rod 1033 to rotate. When the rotating rod 1033 rotates, the end drives the rotating control block 1039 to rotate smoothly in the rotating control groove 1038, so that the fixed cross bar 1034 can rotate smoothly. 32. Stable rotation opens and closes the two folding protective curtains 1030 stably inside the built-in groove 1031, so that the end of the connection hole 103 is located inside the built-in groove 1031 for protection, so that dust is not easy to enter the inside of the speaker seat 102 through the connection hole 103 when the earphone body 100 is not in use, so that dust can be easily prevented from entering through the connection hole 103, and the speaker seat 102 can be used to stably produce sound, thereby improving the built-in dustproof protection effect of the earphone body 100 when in use, prolonging the use effect of the earphone body 100, and when the earphone body 100 is in use, the folding protective curtains 1030 are opened and fixed by the opposite operation, so that the connection hole 103 is exposed to the outside world and the sound can be transmitted to the ear more effectively;

[0036] Finally, when the earphone body 100 is not in use, the folding protective curtain 1030 is closed inside the built-in groove 1031, and the pull rod 1042 is released at this time. The deformation of the compression spring 1043 drives the pull rod 1042 to be elastically connected with the clamping head 1044, until the clamping head 1044 is elastically clamped inside the clamping hole 1045 to fix the rotating knob 104, which is convenient for fixing the rotating knob 104 and the rotating shaft 1034. When not adjusted, it is not easy to cause the torsion gear 2 1036 and the torsion gear 1 1035 to rotate. Stable reinforcement installation and protection are used, which improves the fixity of the installation when the folding protective curtain 1030 is closed for protection when the earphone body 100 is not in use. On the contrary, the folding protective curtain 1030 is also fixed and installed for use after it is opened.

[0037] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
