Referring to fig. 2, fig. 2 is a view of a wearable device according to an embodiment of the present application, where the wearable device includes: at least one earplug, the earplug comprising: the device comprises a first cavity 201, a second cavity 202, a first pressure sensor and a second pressure sensor; the first cavity 201 is communicated with the ear canal (i.e. communicated with the ear canal air) when the wearable device is in a wearing state, and the second cavity 202 is communicated with the atmosphere;
a first pressure sensor 203 for detecting atmospheric pressure of the first cavity 201 using a first frequency and outputting a first electrical signal;
a second pressure sensor 204 for detecting the atmospheric pressure of the second cavity 202 using the first frequency and outputting a second electrical signal;
the wearable device may further include: an amplification comparison circuit, the amplification comparison circuit comprising: an amplifying circuit and a comparing circuit, wherein,
the input end of the first amplifying circuit is connected with a first electric signal, the output end of the first amplifying circuit is connected with one input end of the comparing circuit, the input end of the second amplifying circuit is connected with a second electric signal, the output end of the second amplifying circuit is connected with the other input end of the comparing circuit, and the output end of the comparing circuit is connected with one input/output pin of the processor;
and the processor is used for acquiring the third electric signal of the input/output pin, detecting the second frequency of the third electric signal in the first time interval, and determining whether the earplug is in a wearing state according to the relation between the second frequency and the first frequency.
The wearable device provided by the application realizes that wearing detection is based on changes of air pressure, for the wearable device, taking an earphone as an example, when the earphone is worn in a human ear, a space of an ear canal becomes a closed space, and experiments verify that the air pressure of the closed space is different from the pressure of the external atmosphere, and the air pressure of the closed space is almost unchanged in a wearing state, so that the frequencies between a first electric signal and a second electric signal obtained by setting the same sampling frequency between a first sensor and a second sensor are the same, and the magnitude relation between the first electric signal and the second electric signal is also fixed in the wearing state, so that if the frequency of a third electric signal at the output end of a comparison circuit is the same as the sampling frequency, the wearing state can be determined.
The above determination of the wearing state is based on that the wearable device is relatively fixed in wearing state, i.e. needs to be detected through a set time length, which is highly accurate for detecting actions, because it is unlikely to have good continuity for an action, for example, during a wearing action of the headset, for various reasons, the pressure value of the first cavity 201 and the pressure value of the second cavity 202 may be large or small, which may result in that the first electrical signal sampled by the first pressure sensor may be larger or smaller than the second electrical signal, at this time, after being amplified by the amplifying circuit, because the magnitude relationship between the first electrical signal and the second electrical signal is unstable, the comparing circuit may output a high level or level, which may also change the second frequency of the third electrical signal, so that the value of the second frequency is not necessarily a constant value, and in addition, the second frequency is not completely the same as the first frequency, so that the in-ear misdetection caused by the accident of action is avoided, and the method has the advantages of accurate wearing detection and improvement of user experience.
Optionally, the processor is specifically configured to determine that the earplug is in a worn state if the second frequency is different from the first frequency, and determine that the earplug is in a non-worn state if the second frequency is the same as the first frequency.
Optionally, the processor is specifically configured to determine that the earplug is in the non-wearing state if the first frequency does not change at the set time but the second frequency changes.
Optionally, the processor is further configured to change the first frequency of the first pressure sensor and the first frequency of the second pressure sensor to a third frequency in a second time interval (a time interval after the first time interval), obtain a fourth frequency of the third signal in a second time interval after a delay time t, and determine that the wearable device is in the wearing state if the fourth frequency is the same as the third frequency.
According to the technical scheme, whether the situation of false detection occurs or not is determined by changing the sampling frequency, and the detection accuracy can be greatly improved by the scheme that the detection of the two frequencies is consistent.
