Problems solved by technology

[0003] Specifically, the proximity sensor detects the electrical signal generated when an object approaches the earphone, the pressure sensor detects the pressure in the ear area when the earphone is in the ear, and judges whether the earphone is worn according to whether the electrical signal or the pressure meets the preset conditions. However, the detection result of this method It is not sure that the ear must be the ear or the pressure generated by the ear on the earphone. For example, when people hold the earphone, it will cause the proximity sensor to detect that there is an object approaching the earphone, or the pressure sensor will detect that the earphone is under pressure. In this way, it will It leads to misjudgment of the wearing status of the earphones, affects the accuracy of identifying the wearing status of the earphones, and makes the earphones still work when they are not worn, such as playing music, resulting in power consumption

Embodiment 1

[0033] The embodiment of the present application provides a detection method, figure 1 A schematic flow diagram of an optional detection method provided in Embodiment 1 of the present application, such as figure 1 As shown, the method may include:

[0034] S101: Control the earphone to emit ultrasonic waves and receive reflected sound waves of the ultrasonic waves.

[0035] At present, the detection method of whether the earphone is in the wearing state is generally detected by sensors such as proximity sensors and pressure sensors. The sensor is generally based on whether the value of the signal sensed when the earphone is in the wearing state or when the earphone is not wearing the state meets the preset conditions. To judge whether the earphone is in the wearing state, then, when the size of the pressure signal or electrical signal sensed by the sensor meets the preset conditions, the earphone will be misjudged as being in the wearing state. The detection accuracy of whet...

Embodiment 2

[0054] Based on the above-mentioned embodiments, this embodiment of the present application provides a detection method. Before S101, it is also possible to confirm the preset value range corresponding to the detection point by collecting the reflected sound wave of the ultrasonic wave reflected by the ear cavity when the user wears the earphone. figure 2 A schematic flow diagram of an optional detection method provided in Embodiment 2 of the present application, such as figure 2 As shown, the method may include:

[0055] S201: Control the earphones in the wearing state to emit ultrasonic waves, and receive reflected sound waves of the ultrasonic waves emitted by the earphones in the wearing state;

[0056] S202: Determine a preset value range according to the maximum point of the reflected sound wave of the ultrasonic wave emitted by the earphone in the wearing state.

[0057] It should be noted that when the earphone is in the wearing state, the earphone is controlled to ...

Embodiment 3

[0063] Based on the foregoing embodiments, this embodiment of the present application provides a detection method, Figure 4 A schematic flow diagram of an optional detection method provided in Embodiment 3 of the present application, such as Figure 4 As shown, S202 may include:

[0064] S401: Obtain the coordinate value of the maximum point;

[0065] Here, obtaining the coordinate value of the maximum point includes obtaining the abscissa value and the ordinate value of the maximum point.

[0066] S402: Add the first preset value to the abscissa of the coordinate value of the maximum point as the first reference value to obtain the upper limit value of the abscissa in the preset value range, and set the abscissa of the coordinate value of the maximum point to the first reference value A reference value is reduced by the first preset value to obtain the lower limit value of the abscissa in the preset value range;

[0067] S403: Add the second preset value to the ordinate o...

Abstract

The embodiment of the invention discloses a detection method, a detection device, an earphone, a terminal and a computer-readable storage medium, wherein the method comprises the steps of: controllingthe earphone to transmit ultrasonic wave, and receiving reflected sound wave of ultrasonic wave; according to a pre-set selection rule, selecting a detection point from the reflected sound wave; judging whether all coordinate values of the detection point fall in a pre-set numerical range or not; when all the coordinate values of the detection point fall in the pre-set numerical range, detectingthat the earphone is in a wearing state; and, when at least one value in the coordinate values of the detection point does not fall in the pre-set numerical range, detecting that the earphone is in anon-wearing state.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to a detection method, device, earphone, terminal and computer-readable storage medium. Background technique [0002] At present, with regard to the detection method of the wearing state of the earphone, the wearing state of the earphone is generally detected by a proximity sensor and a pressure sensor. When the earphone is detected to be in an unworn state, the earphone enters a low power consumption mode to avoid power consumption. [0003] Specifically, the proximity sensor detects the electrical signal generated when an object approaches the earphone, the pressure sensor detects the pressure in the ear area when the earphone is in the ear, and judges whether the earphone is worn according to whether the electrical signal or the pressure meets the preset conditions. However, the detection result of this method It is not sure that the ear must be the ear...
