Embodiment 1

[0036] In the following, reference will be made to image 3 and Figure 4 A specific example of an approach judging method and an associated electronic device according to an exemplary embodiment of the present invention will be described.

[0037] image 3 A specific example of the proximity judging method according to an exemplary embodiment of the present invention is illustrated, and Figure 4 A specific example of a first electronic device and a second electronic device according to an exemplary embodiment of the present invention is illustrated.

[0038] For example, the approach judging method according to an exemplary embodiment of the present invention can be applied to the following situations: such as Figure 4 As shown, the first electronic device is a cell phone 500 and includes a first speaker 510 , while the second electronic device is a wireless headset 600 and includes a second speaker 610 . In this case, the proximity determination method according to the...

Embodiment 2

[0050] In the following, reference will be made to Figure 3 to Figure 6 The step S310 of sensing an induced voltage and the step S320 of generating a voltage to be compared in the proximity judging method according to an exemplary embodiment of the present invention will be described in detail.

[0051] Figure 5 Illustrated image 3 In the specific example of the step S310 of sensing the induced voltage, and Figure 6 Illustrated image 3 The step S320 of generating the voltage to be compared in the specific example.

[0052] The inventor noticed that in practical applications, since the first loudspeaker in the mobile phone is often used to receive the audio signal output by the audio amplifier in the mobile phone, so as to listen to music, play incoming ringtones or answer calls in an external way, so at this time , the user may not want to use the first speaker to judge whether the wireless headset is close to the mobile phone, so as not to affect the sound quality of...

Embodiment 3

[0066] In addition, after the comparison and judgment module in the mobile phone judges that the wireless headset is close to the mobile phone, we can also use this judgment result to perform various subsequent processing, for example, automatically establish a wireless communication connection between the two.

[0067] In the following, reference will be made to Figure 4 and Figure 7 The method for automatically establishing a communication connection implemented by the approach judging method according to an exemplary embodiment of the present invention will be specifically described.

[0068] The inventor further noticed that: due to the continuous enhancement of the functions of various electronic devices, the design of the menu options is becoming more and more complicated; the user often needs to enter the multi-level menu and perform tedious selection and confirmation before activating the wireless communication function of the electronic device , and then search for...

Abstract

The invention discloses an approaching judgment method and equipment and a state switching method and equipment. The approaching judgment method is applied to first electronic equipment which is composed of a first loudspeaker. The approaching judgment method includes sensing an induced voltage produced by the first loudspeaker, the induced voltage is produced by the first loudspeaker due to the fact that second electronic equipment moves opposite to the first electronic equipment, wherein the second electronic equipment comprises a second loudspeaker. Voltage to be compared is produced according to the induced voltage; the voltage to be compared is compared with threshold voltage; and if the voltage to be compared is larger than or equal to the threshold voltage, the second electronic equipment and the first electronic equipment are confirmed to be approached.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, the present invention relates to a method and device for approach judgment, and a method and device for switching states of a wireless communication module. Background technique [0002] In recent years, various wireless communication technologies such as Near Field Communication (NFC), Wi-Fi, Bluetooth, and infrared have emerged in an endless stream. With the continuous development and popularization of these wireless communication technologies, electronic devices such as mobile phones, computers, speakers and the like all have wireless communication functions. This function eliminates the hardware connection between two or more electronic devices, realizes their easy interconnection, and greatly facilitates the use of users. [0003] For example, the application of this wireless communication function can be to wirelessly connect a mobile phone to electroni...
