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...
