FIG. 1 a is a schematic flowchart of a method for adjusting parameters based on ultrasonic waves provided in Embodiment 1 of the present invention. This embodiment can be applied in the following scenario: the user wants to adjust specific parameters of the mobile terminal in a non-contact manner. The ultrasonic-based parameter adjustment method provided in this embodiment can be applied to a mobile terminal having an ultrasonic sensor. The method may be performed by an ultrasonic-based parameter adjustment device, which is implemented by software and/or hardware and configured in a mobile terminal. The mobile terminal may be a mobile electronic device, such as a smart phone, a tablet computer, a notebook computer, etc., which has a processor and a memory and is compatible with ultrasonic technology.

Referring to Figure 1a, the method specifically includes:

Step 110: Identify the user's gesture action on the side of the mobile terminal through the ultrasonic sensor in the mobile terminal.

As shown in Figure 1b, the ultrasonic sensor includes two parts, a transmitting end 111 for transmitting ultrasonic waves, and a receiving end 112 for receiving ultrasonic waves. Fig. 1c is a schematic diagram of the working principle of the ultrasonic sensor in the first embodiment of the present invention. As shown in Fig. 1c, when an object approaches, the ultrasonic wave emitted by the transmitting end 111 will be reflected on the surface of the object, and the receiving end 112 will receive the reflected ultrasonic wave . The approach distance of the object can be obtained through the algorithm of the difference between the transmitting time and the receiving time, the ultrasonic sound speed, and the differential filtering algorithm. According to different settings of IC (Integrated Circuit, integrated circuit) and software algorithm, the accuracy of distance measurement reaches the millimeter (mm) level, and the full scale is about 150-200cm. When the receiving end 112 of a plurality of ultrasonic sensors is arranged in the mobile terminal, the mobile terminal can detect approaching and moving away from the side of the mobile terminal through the ultrasonic sensors, that is, the ultrasonic sensor can recognize the user's gesture on the side of the mobile terminal action.

In this embodiment, the ultrasonic sensor includes at least two receiving ends and at least one transmitting end; wherein, one of the at least two receiving ends and the at least one transmitting end is disposed on the screen of the mobile terminal together with the at least one transmitting end. The upper half of the mobile terminal is arranged near the top of the mobile terminal casing, and the other receiving end of the at least two receiving ends is arranged on the lower half of the mobile terminal screen or near the bottom of the mobile terminal casing. The speaker of the mobile terminal is multiplexed to transmit ultrasonic signals (that is, the speaker is used as the ultrasonic transmitting end), and the microphone of the mobile terminal is multiplexed to receive the reflected ultrasonic signal (that is, the microphone is used as the ultrasonic receiving end), which not only enriches the functions of the speaker and the microphone. In addition, there is no need to configure separate receivers and transmitters in the mobile terminal to recognize user gestures, and the space in the mobile terminal and the manufacturing cost of the mobile terminal can also be saved.

The ultrasonic wave emitted by the transmitter will generate reflection echoes in different directions when it encounters the user's hand, and at least two receivers receive at least two reflection echoes in different directions. The distance between the user's hand and the two receiving ends at the moment, and then the three-dimensional coordinates of the user's hand are obtained, so that the coordinates of the user's hand at a specific moment can be obtained. In order to make the obtained coordinates more accurate, at least one receiving end is arranged on the upper half of the screen, and at least one receiving end is arranged on the lower half of the screen, which can recognize the user's gestures on the side of the mobile terminal.
