It should be noted that the use of the private lover's first application to clarify this April's intention is not a limitation of the present invention. For example, in the case of a user, the field user closes the electronic device 100 to other parts of the body to make the wireless communication _#. (4) The village can change as 201232923 Please refer to Figure 2, which is a functional block diagram of the embodiment of the electronic device. As shown, the electronic device 100 & includes (but is not limited to) a sensing unit ιι, - a control unit 120 and a - wireless communication module 13 。. The sensing unit is configured to generate a sensing result S_ResuIt, wherein the sensing unit 1 〇〇 is mainly caused by the electronic device 100 approaching the user (as shown in FIG. 1 ), resulting in the sensing unit 1〇〇 The received energy produces a change, thereby producing a ❹丨 result s-ResuIt. Therefore, the sensing result S_Result can indicate a current separation distance d between the electronic device and the user. Wherein, the sensing unit may be a thermal sensing component (eg, an infrared sensor). In general, any object with a temperature above the absolute temperature will emit more or less infrared light, and the principle of the infrared sensor (passive infrared sensor) is the received radiant energy (ie ' When the infrared energy produces a change, a charge is generated, which will cause a change in the sensed signal of the output. In general, the charge change of the sensor outside the red line has a proportional relationship with the temperature change. On the other hand, if the sensing unit 110 is implemented by an infrared sensor, the infrared sensor can be used to determine whether the human body is close to the electronic device lake by utilizing the sensitivity of the infrared sensor to the change of the light energy. Although the human body is close to the f-subject device, the sensing unit 110 composed of infrared rays receives more infrared rays that are lightly emitted by the human body, thereby generating more electric charge. ,. In order to record a large sensing value, when the electronic device is excited when the human body is away, the sensing unit 110 receives the infrared rays with relatively little contact, so such a change may cause the sensing unit 110 to record a small amount of electric charge. , so that the value is reduced. Based on such a concept, the sensing unit U〇 of the present invention can use the change in the sensed value to determine a current separation distance between the electronic device 100 and a user. 201232923 In practice, the sensing unit 110 may be disposed on a different side from the display screen of the electronic device 1〇〇. As shown in Fig. 3, the display screen 14 is disposed on the front side of the electronic device 1A, and the sensing unit 110 is disposed on the back surface of the electronic device 1A. Moreover, the control unit 120 is coupled to the sensing unit no and the wireless communication module 13A, and changes the operational characteristics of the wireless communication module 130 according to the sensing result S_ReSUlt. Preferably, the control unit 120 changes the signal transmission characteristics of the wireless communication module 13 according to the sensing result S_Result. In addition, the wireless communication module 130 may perform wireless transmission according to specifications such as IEEE 8〇2 u, WCDMa or Wireless USB (however, these specifications are not limited by the present invention).

However, it should be noted that, in addition to the above listed possible electronic devices, any other electronic device having a wireless communication module, and having circuit elements functional and similar to the sensing element 110 and the control unit 12, are all of the present invention. Fan Ming. If the sensing result S_Result indicates that the current separation distance D falls within a specific range (which may be regarded as the body part of the user is close to the electronic device 100), at this time, the control unit 120 controls the wireless communication module 130 to reduce its location. Generates the energy of one of the transmitted signals. By changing the energy of the transmitted signal, the high-frequency radiation 201232923 absorbed by the user can be effectively reduced. In the Keshi Guan towel of the present invention, Ke's way is provided to specifically realize the concept of reducing the emission of the signal. In the present invention, in the present invention, when the sensing result S_Result indicates that the current separation distance D falls within the specific range, the control unit 120 reduces the gain value of the power amplifier 132 to reduce the energy of the transmitted signal. . In addition, in the embodiment of the present invention, the control unit 12G works to adjust the antenna module 134 to change the signal transmission characteristics of the wireless communication module 13A. Therefore, when the sensing result S-ReSUlt indicates that the current separation distance D falls within the specific range, the control unit 12 adjusts the impedance value of the antenna module 134 to reduce the energy of the transmitted signal. In detail, the energy intensity of the transmitted signal generated by the antenna module 134 is related to the impedance matching between the antenna module 134 and the front end circuit (such as the 'power amplifier 132). Therefore, when the impedance does not match, some of the signal energy is reflected back to the front-end circuit. In this case, the energy of the transmitted signal generated by the antenna module 134 is lower than the energy of the impedance matching. Therefore, the present invention deliberately weaves the impedance into a non-matching situation, thereby reducing the energy of the transmitted signal. . In addition to the above two methods, by changing the energy of the transmitted signal to reduce the south astigmatism energy absorbed by the user, in addition to the embodiment of the present invention, by changing the antenna directivity of the antenna module 134 To achieve the same purpose. Further, when the gain of the antenna module 134 in different directions is adjustable (for example, the antenna array " can increase the gain value of the antenna module in a direction in which the receiving end is located, and reduce the direction in other directions. The gain value is used to reduce the amount of high-frequency radiation absorbed by the user. The receiving end may be - (WiFeless _ss pGint, WAp) or - mobile communication base station. By adjusting this way, the same can be reduced. High-frequency radiation absorbed by the person 201232323 Energy. Another implementation should pay particular attention to the fact that the "one embodiment" or "another embodiment" mentioned above represents a specific feature described for the embodiment, , a gentleman structure or a characteristic system is included in at least one embodiment of the present invention. Therefore, although the various features are mentioned in the description of different embodiments, different structural features or method features are mentioned. The two embodiments of adjusting the antenna directivity of the antenna module 134 can be adjusted with the antenna mode by appropriately modifying the implementation manner in a specific embodiment. The embodiment of the impedance value of the group j 34 is mutually mutually & σ, which can reduce the harm of the high-frequency radiation energy to the human body, and ensure the quality and reliability of the wireless transmission line. (1) The illusion is based on the aforementioned concept, An embodiment of the present invention provides a method for controlling a wireless communication module (such as a wireless communication module 13A). The flowchart of the method is not shown in FIG. 4, and the present invention is in step S410. The method generates a _ result according to the change of the igniting energy received by the wireless communication module, wherein the domain is determined to indicate a current separation distance between the communication module and the user. Then, in the step The method of the invention further changes the operation of the wireless communication module according to the sensing result. Preferably, the operating characteristic of the wireless communication module is a signal transmission characteristic. Furthermore, the wireless communication group is modified. The operation stealing step S· further includes: when the sensing result, the current separation distance falls within a specific range, and controls the wireless communication module to generate energy of the __transmitted signal generated by the wireless communication module. Step by step In fact, the energy of the transmitted signal generated by the 5 hai wireless communication module may be one of the following two methods: 201232923: lowering the wireless communication module - a power amplifier (such as: one of the power amplifiers) Gain value; or adjust the _day, miscellaneous group (such as one impedance value ' of the wireless communication group to reduce the energy of the transmitted signal. In addition, the present method can also be achieved by changing the directivity of the day group. The purpose of reducing the high frequency radiant energy absorbed by the user is reduced. Therefore, in one embodiment of the method of the present invention, 'step S42 〇 may include: when the sensing result indicates that the current separation distance falls within a specific range Controlling the wireless communication module to adjust the antenna directivity of one of the antenna modules 2. Preferably, the method of the present invention increases the gain value of the antenna module in a specific direction, and the specific direction is directed A receiving end. Similarly, the embodiment of adjusting the antenna directivity of the antenna module can be combined with the embodiment for adjusting the impedance value of the antenna module, thereby reducing the risk of high frequency and light energy to the human body, and ensuring wireless transmission. Connection quality and reliability. In summary, the 'invention of the present invention is that the sub-device is close to the body part of the side to adjust the emission reduction characteristics of the wireless communication module, thereby reducing the risk that the high-frequency Korean energy may pose to the user's health. The above description is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made by the scope of the present invention should be covered by the present invention. 201232923 [Simple description of the drawing] FIG. 2 is a functional block diagram of an embodiment of an electronic device according to the present invention.
