[0035] In order to solve the aforementioned problem that the earphones are easily lost after falling and the earphones and the earphone box are heavy due to the magnetic attraction structure, the present invention proposes an earphone fixing device.

[0036] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] In order to illustrate the structure of the earphone fixing device provided by the present invention, Figures 1 to 4 The structure of the earphone fixing device is exemplarily indicated from different angles. Specifically, Figure 1 The structure of the earphone fixing device according to an embodiment of the present invention is shown; Figure 2 The side view structure of the earphone fixing device according to the embodiment of the present invention is shown; Figure 3 The top view of the earphone fixing device according to the embodiment of the present invention is shown; Figure 4 The three-dimensional structure of the earphone fixing device according to the embodiment of the present invention is shown.

[0038] like Figures 1 to 4 As shown together, the earphone fixing device provided by the present invention includes: two earphones 2 (respectively a right earphone 21 and a left earphone 22), and an earphone groove is arranged at the bottom of the ear handle of each earphone 2; an earphone box 1, a button 4 is arranged on the outside of the earphone box 1, a force transmission column 32 connected to the button 4 and arranged inside the earphone box 1, and an elastic metal lock buckle 521 connected to the force transmission column 32, and an earphone compartment 62 for accommodating the earphones 2 and symmetrically distributed is arranged inside the earphone box 1; wherein the force transmission column 32 includes an extension portion 321 and a connecting portion 322, One end of the extension portion 321 is connected to the button 4, and the other end passes through the interior of the earphone box 1 to the side away from the button 4 and is vertically connected to the connecting portion 322. The connecting portion 322 is connected to the elastic metal lock buckle 521; the elastic metal lock buckle 521 is arranged in each of the earphone compartments 61 and corresponds to the position of the earphone groove. When the earphone 2 is fully placed in the earphone compartment 61, the elastic metal lock buckle 521 is locked in the earphone groove. When the button 4 is pressed, the elastic metal lock buckle 521 is unlocked by the inner recess transmitted by the force transmission column 32.

[0039] exist Figure 2 and Figure 3 In the embodiment shown, the earphone 2 in the earphone box 1 is fixed by a single-end locking method, and the force transmission column 32 is arranged on a side of the earphone box 1 away from the button. One end of the extension portion 321 is connected to the button 4, and the other end passes through the earphone box 1 to the side away from the button 4 and vertically connects to the connection portion 322, and the connection portion 322 is connected to the elastic metal lock buckle 521.

[0040] The transmission column 32 further includes two non-metal elastic sheets 52 , one end of the two non-metal elastic sheets 52 is respectively connected to the two ends of the connecting portion 322 , and the other end is connected to the elastic metal lock buckle 521 .

[0041] A torsion spring 73 is provided at one end of the non-metallic elastic sheet 32 ​​, and the non-metallic elastic sheet 32 ​​is movably connected to the connecting portion 322 via the torsion spring 73 , and the torsion spring 73 realizes the inner concavity and outer convexity of the elastic metal lock buckle 521 .

[0042] In an embodiment of the present invention, the specific process of locking the earphone is as follows: when the earphone 2 is placed in the earphone compartment 62, the elastic metal lock buckle 521 is compressed by force to make the torsion spring 73 concave; when the earphone 2 is completely placed in the earphone compartment 62, the force disappears, and the torsion spring 73 drives the elastic metal lock buckle 521 to convexly lock.

[0043] The connecting portion 322 is connected to the earphone box 1 via a spring 74. The connecting portion 322 is subjected to force and moves along the force direction to compress the spring 74. When the force disappears, the spring 74 rebounds to its original state.

[0044] In an embodiment of the present invention, the specific process of unlocking the earphone is as follows: the button 4 is pressed by an external force, and the non-metallic elastic sheet 52 is driven to move along the force direction through the force transmission column 32. Under the action of the spring 74, the non-metallic elastic sheet 52 will cause the elastic metal lock buckle 521 to be recessed and unlocked.

[0045] Among them, the earphone groove is arranged at the near-ear end of the earphone 2. The earphone 2 is fixed by the elastic metal lock buckle 521 contacting the earphone groove at the end of the ear handle of the earphone. The contact point between the elastic metal lock buckle 521 and the earphone groove at the end of the ear handle of the earphone can not only lock the earphone but also serve as a charging port for charging the earphone. The first metal lock buckle and the corresponding earphone groove form a pin point for charging the earphone box, and when the earphone 2 is locked, the two pin points are connected for charging. The elastic metal lock buckle 521 is the pin point for the earphone box 1 to charge the earphone 2, and the pin point is arranged in the earphone compartment 62. In addition, a telescopic charging port 82 is arranged at the bottom of the earphone compartment 62 for charging the earphone 2 in the earphone box 1.

[0046] The principle of the earphone fixing device in the embodiment of the present invention is as follows: when the earphone 2 is inserted into the earphone box 1, it is stressed and transmits the force to the non-metallic elastic sheet 52, and the non-metallic elastic sheet 52 is stressed to wind around the torsion spring 74. When the earphone 2 is completely placed in the earphone box 1, the non-metallic elastic sheet 52 rotates to make the elastic metal lock 521 contact with the earphone groove of the corresponding earphone, and fixes the earphone in the earphone compartment 62 to fix the earphone. When the button 4 is pressed, the force transmission column 32 drives the non-metallic elastic sheet 52 to press the spring 74 to bring the elastic metal lock 521 out of the earphone compartment 62 to unlock, and the elastic metal lock is reset when the button is released.

[0047] It can be seen from the above embodiments that the earphone fixing device provided by the present invention fixes the earphone in the earphone box in a single-ended locking manner by combining the force transmission column, the elastic metal lock buckle and the earphone groove, thereby preventing the earphone from falling out of the earphone box after falling. In addition, compared with the traditional magnetic suction structure, this device structure can effectively reduce the weight of the earphone and the earphone box.
