It should be understood that the embodiments shown in Figures 2A to 2D are intended to illustrate that the metal sheet 4 can be connected to any position of the mobile phone 3 in any shape, and are not intended to limit the embodiments of the present invention to the above four methods, wherein, The mobile phone 3 can be a mobile phone of various brands, including the case material of the mobile phone being plastic or metal, which can be applied to the present invention.

Among them, the embodiment of connecting the metal piece L1 of any shape to any mobile phone L4 through the method of non-contact coupling L2 via the mobile phone case L3, the metal piece can be directly connected to the mobile phone case by referring to the above-mentioned implementation or by using Figure 3A and Figure 3B As shown in the example, it is connected to the pull tab and is matched with the chute structure of the mobile phone case so that the pull tab can slide back and forth on the mobile phone case to adjust the frequency of the antenna coupling.

As shown in Figure 3A, the body 1 of the mobile phone case is shaped according to the appearance of the mobile phone to form a protective case for placing the mobile phone.

The main body 1 forms a rectangular hole in the middle of the upper half of the placement surface 12, and a slide rail structure is formed on the side of the two holes to form a chute 122. The placement surface 12 is also formed with a hole 121, so that the mobile phone case can be combined with the mobile phone after use. The camera lens will not be blocked.

At least one side hole 111 is formed on the side 11 of the main body 1 to provide space. When the mobile phone case is combined with the mobile phone, the user can press the standby button, the sound control button and other buttons; and can insert earphones, chargers and other devices.

It should be noted that the above-mentioned hole 121 and the side hole 111 are formed with devices included in the mobile phone, such as a camera lens, an earphone hole, and a charger hole. If the mobile phone does not have the above-mentioned devices, the present invention can also be formed without the above-mentioned hole 121 And the aspect of side hole 111.

The pull tab 2 is formed in response to the rectangular appearance of the chute 122 and formed on its side to match the design of the slide rail structure, so that the pull tab 2 can slide between the chute 122. The plane of the pull tab 2 facing the position where the mobile phone is placed is The first face; the plane relative to the first face is the second face. In addition, the pull tab 2 is provided with a metal sheet 21 on the first surface, wherein the arrangement method may be, but not limited to, the two are glued together.

As shown in Figure 3B, the body 1 of the mobile phone case is shaped according to the appearance of the mobile phone to form a protective case for placing the mobile phone.

The main body 1 forms a hole 121 on the placement surface 12, so that the camera lens of the mobile phone will not be blocked after the mobile phone case is combined with the mobile phone.

The main body 1 forms a rectangular hole in the lower half of the right side of the side surface 11 , and forms a slide rail structure on the sides of the two holes to form a chute 112 . The body 1 is formed with at least one side hole 111 on the side 11 to provide space. When the mobile phone case is combined with the mobile phone, the user can press the standby button, the sound control button and other buttons; and can insert earphones, chargers and other devices.

The pull piece 2 is shaped according to the rectangular appearance of the chute 112 and formed on its side to match the design of the slide rail structure, so that the pull piece 2 has to slide between the chute 112, and the pull piece 2 faces the plane where the mobile phone is placed is the first face; the plane relative to the first face is the second face. In addition, the pull tab 2 is provided with a metal sheet 21 on the second surface, wherein the arrangement method may be, but not limited to, the two are glued together.

It should be understood that the two embodiments shown in FIG. 3A and FIG. 3B are intended to illustrate that when the chute structure is used as an implementation mode for arranging the metal sheet on the mobile phone case, it is not intended to limit the embodiment of the present invention to the above-mentioned Two methods. Among them, the metal sheet is not limited to forming the chute structure into any shape or being arranged on any part of the body 1; the metal sheet 21 is not limited to being arranged on the first surface of the pull tab 2, but can also be arranged on the second surface, or A slot is opened in the pull tab 2, and the metal sheet 21 is put in and then covered with another metal sheet and fused, so that it is arranged inside the pull tab and cannot be viewed from the outside. In addition, since the pull tab 2 is designed to be slidable to couple the antenna frequency to achieve the best effect, the pull tab 2 does not necessarily need to slide to adapt to different types of mobile phones. In the case of a good effect, the metal sheet 21 can be directly disposed in the body 1 without going through the pull sheet 2 .

When the user uses the mobile phone combined with the mobile phone case of the present invention, if he feels that the wireless network of the mobile phone, the mobile phone mobile network, the Bluetooth transmission device, and the communication device are not well received, he can pull the pull tab 21 to a certain point, and through the contact on the pull tab 21 The metal sheet changes the frequency response of the antenna, so as to enhance the receiving capability of the wireless device of the mobile phone. Among them, the fixed point to be pulled depends on the antennas of various mobile phones, and it may not be necessary to pull the pull sheet 21 to achieve the best receiving ability.

It should be understood that in order to achieve the best performance of the present invention, the grooves and pull tabs need to be shaped to match the antenna position of the mobile phone to produce the best results. However, as mentioned in the previous paragraphs, the grooves and pull tabs It is not limited to be formed with the receiving antenna, and the two can be formed at any position, which also has the effect of strengthening the receiving antenna.

Voltage standing wave ratio (VSWR) is a pointer unit used to measure the severity of impedance mismatch, usually expressed as X to 1 or directly represented by X. The smaller the value of X, the closer it is to 1, which means that the impedance values of all components in the system are almost the same, that is, the closer to the ideal state. In order to prove that the present invention clearly has the effect of enhancing the receiving function, the applicant of the present invention actually measured the VSWR of the mobile phone without the structure of the present invention and the mobile phone with the structure of the present invention (as shown in FIG. 4 ). It can be seen from Fig. 4 that at various frequencies, the VSWR of the antenna before using the present invention is higher than the VSWR after using the present invention, for example, at a frequency of 1600MHz, the VSWR is reduced from 6 to about 2.3, and at a frequency of 2000MHz, the VSWR is reduced from 3 down to about 1.9. It is not difficult to find the function of the present invention via FIG. 4 .

The above-mentioned are only preferred embodiments for explaining the present invention, and are not intended to limit the present invention in any form. Therefore, any modification or change of the present invention made under the same spirit of the invention, All should still be included in the category that the present invention intends to protect.
