[0018] As Figures 1-4 shown, a mobile phone earpiece connection structure includes a mobile phone case 1, a substrate 2 and an earpiece main body 3. The substrate 2 is arranged inside the mobile phone case 1. A connection and fixing structure 7 is provided on the earpiece main body 3, and the lower end of the connection and fixing structure 7 is connected to the substrate 2. A groove is provided on the substrate 2, and a clamping hole is provided on the substrate 2. The earpiece main body 3 is arranged in the clamping hole on the substrate 2. A positive contact piece and a negative contact piece are provided on the substrate 2. A positive pin 4 is provided on the earpiece main body 3, and a negative pin 5 is provided on the earpiece main body 3.

[0019] When installing the mobile phone earpiece, the substrate 2 is arranged inside the mobile phone case 1. The earpiece main body 3 is placed inside the mobile phone case 1 to ensure that the earpiece main body 3 is located at the groove on the substrate 2. The connection and fixing structure 7 is arranged on the earpiece main body 3. The lower end of the connection and fixing structure 7 is connected to the substrate 2, and the upper end presses and fixes the earpiece main body 3. At the same time, the two groups of connection and fixing structures 7 electrically connect the positive pin 4 and the negative pin 5 to the positive contact piece and the negative contact piece on the substrate 2 respectively to ensure electrical connection between the earpiece main body 3 and the substrate 2. After the installation of the earpiece main body 3 is completed, it can be used continuously.

[0020] Through the above implementation, the connection and fixing structure 7 includes a butting plate 701, a connecting plate 702, a plug 703 and a fastening assembly 705. The butting plate 701 is fixedly connected to the connecting plate 702. The plug 703 is arranged on the connecting plate 702. The fastening assembly 705 is installed on the butting plate 701 and is connected to the earphone main body 3. The connection and fixing structure 7 further includes an elastic pressing plate 704. The two butting plates 701 are respectively in contact with the positive pin 4 and the negative pin 5. The plug 703 is connected to the clamping hole on the substrate 2. The elastic pressing plate 704 is arranged on the butting plate 701 and abuts against the earphone main body 3. The fastening assembly 705 includes a fixing frame 7051, a rotating block 7052, a pin shaft 7053, a plug 7054, an elastic plate 7055, a spring 7056 and a control column 7057. The fixing frame 7051 is fixedly installed on the butting plate 701, and a rotating groove is provided on the fixing frame 7051. The rotating block 7052 is rotatably installed in the rotating groove on the fixing frame 7051 through the pin shaft 7053. The plug 7054 is fixed to the lower end of the rotating block 7052 and is inserted into the slot 6. The elastic plate 7055 is connected to the upper end of the rotating block 7052. The spring 7056 is installed on the lower surface of the elastic plate 7055, and the lower end of the spring 7056 abuts against the earphone main body 3. The control column 7057 is fixed to the end of the elastic plate 7055. By providing the connection and fixing structure 7, when installing the mobile phone earphone using the butting plate 701, in addition to pressing the two pins, the elastic pressing plate 704 is also used to press the earphone main body 3, thereby improving the pressing effect on the entire mobile phone earphone. A slot 6 is opened on the earphone main body 3 and used in cooperation with the fastening assembly 705. The plug 7054 is connected to the slot 6, which plays an auxiliary tightening effect on the earphone main body 3, can enhance the stability of the earphone main body 3 after installation, prevent loosening, and ensure the use effect. The rotating block 7052 is installed on the fixing frame 7051 through the pin shaft 7053 and used in cooperation with the elastic plate 7055 and the spring 7056. It can be quickly flipped and loosened for easy disassembly, and can also play an elastic support effect in the normal state, ensuring that the plug 7054 is firmly set in the slot 6 and guaranteeing the tightening effect of the fastening assembly 705 on the earphone main body 3.

[0021] When installing the earphone main body 3, place the earphone main body 3 into the mobile phone case 1. The abutting plate 701 in the connection fixing structure 7 abuts against the corresponding pin, and the insertion block 703 at the connecting plate 702 is arranged in the clamping hole on the substrate 2, so as to be tightly fixed at the pin. At the same time, the elastic pressing plate 704 presses the earphone main body 3. During the installation process, the control column 7057 pulls and presses down the elastic plate 7055, and the two elastic plates 7055 tend to move towards the middle part and compress the spring 7056, so that the rotating block 7052 rotates on the fixing frame 7051 through the pin shaft 7053, thereby opening the plug 7054. When the abutting plate 701 is installed, release the action on the control column 7057. Under the elastic action of the elastic plate 7055 and in cooperation with the spring 7056, the rotating block 7052 flips and resets through the pin shaft 7053, and the plug 7054 is inserted into the slot 6. Under the elastic action, the fastening assembly 705 plays an auxiliary abutting role on the earphone main body 3, thereby being able to strengthen the fixing effect on the earphone main body 3 and ensure the stability of the earphone main body 3 during use. If disassembly is required, the control column 7057 can be used to drive the elastic plate 7055 to move, and the elastic plate 7055 drives the rotating block 7052 to flip, so that the plug 7054 is removed from the slot 6, and then the entire connection fixing structure 7 can be removed. The structure is simple and the operation is convenient and fast.
