Embodiment Construction

[0021] Below in conjunction with accompanying drawing, further illustrate how the present invention is implemented:

[0022] as attached figure 1 , 2 As shown, before blowing air: the voltage on the signal of the microphone 10 is its bias voltage, which is obtained by dividing the battery voltage 11 through two MIC_BIAS voltage dividing resistors 4, and it always exists when the microphone is turned on and off. The value of this voltage needs to meet the minimum value of the high-level input of the mobile phone signal. The content in the dotted box is an optional module, in which the low-pass filter 5 is for more accurate detection of the blowing sound (the blowing sound of the microphone is mainly low-frequency, and the high-frequency components that are not blowing sounds can be filtered out by low-pass filtering ), the NOT gate 6 is used for the mobile phone chip logic high level power-on situation (the NOT gate directly bypasses when the logic level is low). Assuming th...

Abstract

The invention discloses an air blowing on-off method of a mobile phone. According to the method, air is blown to the mobile phone with a relatively large volume in a non-contact short distance. The air blowing action causes an air extrusion. When extruded air enters a microphone equipment, a sound pressure characteristic of the microphone when air blows causes a substantial change to the signal microphone bias voltage triggers a logic interruption of signals of the microphone. Once the change of a logic level is applied to on-off pins of chips of mobile phones, an on-off event will be triggered, thereby an on-off function of mobile phones can be realized. The method provides a novel and fashionable method for the on-off ways of mobile phones, and simultaneously makes a mobile phone product independent of entity on-off switch and method, providing a full touch screen mobile phone without any buttons.

Description

technical field [0001] The invention relates to a novel method for turning on and off a mobile phone. The method realizes the function of turning on and off the mobile phone by blowing air at a relatively large volume in a non-contact close range. [0002] The invention of this method not only provides a very novel and fashionable method for switching on and off the mobile phone, but also enables the mobile phone product to be separated from the physical button switch and the method, and make a full touch-screen mobile phone without any buttons. Background technique [0003] At this stage, the switch and method of mobile phone products are basically physical button switch mode. This traditional boot method needs to add a power button. A method for turning on and off the mobile phone by blowing air is different from the traditional starting method. The method realizes the function of turning on and off the mobile phone by blowing air at a relatively large volume at a short di...
