Recording the transmission time of the ultrasonic wave from the start of transmission to the reception of the ultrasonic wave, and calculating the transmission distance of the ultrasonic wave on the display surface of the terminal by a calculation method of dividing the distance by the time according to the preset ultrasonic wave transmission distance, wherein the ultrasonic wave transmission distance is 2 times the distance between the receiver and the microphone, as shown in fig. 5.

Specifically, the principle by which the transmission speed of ultrasonic waves is measured is as follows:

when the ultrasonic wave is emitted by the ultrasonic generator, timing is started until the ultrasonic wave is propagated to the ultrasonic receiver through air, the timing is stopped, the measured transmission time is t, and the distance L between an ultrasonic wave emitting place and a target can be calculated according to the following formula;

L＝ct/2；

wherein, c is the propagation velocity of ultrasonic wave in the air, and the measurement of transmission time t can adopt the method of singlechip pulse count, can accurate measurement, converts time t into pulse count quantity N, then has:

L＝Nc/2f；

wherein, N is the number of counting pulses, and f is the frequency of counting pulses.

The preset temperature is a preset temperature threshold, and whether the temperature of the terminal is too high can be judged by comparing the measured terminal with the temperature threshold.

Specifically, when the terminal temperature is within a temperature range, the maximum temperature value in the temperature range is compared with the preset temperature, and if the maximum temperature value is greater than the preset temperature value, the terminal temperature is considered to be greater than the preset temperature, and the temperature of the terminal is considered to be too high, so that the user needs to be reminded, or the temperature of the terminal is reduced while the user is reminded.

Optionally, when the terminal temperature is a temperature value, the terminal temperature is directly compared with a preset temperature, and if the terminal temperature is greater than the preset temperature value, the terminal temperature is considered to be too high, and the user needs to be reminded, or the terminal temperature is reduced while the user is reminded.

Specifically, the user may be reminded that the temperature of the terminal is too high by displaying a prompt message on the terminal display screen, for example, as shown in fig. 7.

Optionally, if the temperature of the terminal is detected to be higher than the preset temperature, the terminal can also send a reminding sound, and the terminal is reminded of the user through the reminding sound that the temperature of the terminal is too high.

Specifically, the user can set different prompt tones to remind the user that the temperature of the terminal is too high, so as to inform the user of cooling the terminal in time.

Optionally, if the terminal temperature is detected to be higher than the preset temperature, the terminal may further display the terminal shell as a color corresponding to the terminal temperature, so that the user is reminded of the too high temperature of the terminal through the color of the terminal shell.

Specifically, the shell of the terminal can be made of a temperature sensing material, and the temperature sensing material displays different colors when contacting different temperatures, so that a user can know the temperature of the terminal through the color change of the shell of the terminal, and the user can be reminded that the temperature of the terminal is too high.

Optionally, if the terminal temperature is detected to be higher than the preset temperature, the terminal may further display a display lamp on the terminal housing as a color corresponding to the terminal temperature, so that the user terminal is reminded of the too high temperature through the color of the display lamp on the terminal housing.

Specifically, a display lamp can be arranged on the shell of the terminal, different bright colors of the display lamp correspond to different temperatures of the terminal, and therefore when the temperature of the terminal is detected to be too high, the user terminal can be reminded of the fact that the temperature of the terminal is too high through the colors of the display lamp.

Step 405, the terminal temperature is reduced by reducing the frequency of the CPU of the terminal.
