In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a wireless headset in-box detection method according to an embodiment of the present invention.
The wireless earphone in-box detection method is applied to a wireless earphone and comprises the following steps:
step S1: and detecting the capacitance value of a first touch key arranged on the surface of the wireless earphone.
Step S2: and when the capacitance value is larger than a preset in-box induction threshold value, determining that the wireless earphone is in the box.
The preset box-entering induction threshold value is set according to a second touch key which is arranged in the charging box and is grounded, and after the wireless earphone is placed in the box, the capacitance value generated when the second touch key contacts the first touch key is larger than the capacitance value generated when a human hand touches the first touch key.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, considering that the surface of the wireless headset is provided with the first touch key (capacitive touch screen), when a human hand touches the first touch key, a capacitance value generated by the human hand is superposed on the first touch key, so that the capacitance value fed back to the wireless headset by the first touch key is increased, and the wireless headset can determine whether the first touch key is being touched by a user based on the capacitance value change of the first touch key.
Based on the principle, the second touch key (capacitive touch screen) is arranged inside the charging box, and the second touch key is grounded. When the wireless earphone is plugged into the box, the second touch key is in contact with the first touch key, the capacitance value generated by the second touch key is superposed on the first touch key, so that the capacitance value fed back to the wireless earphone by the first touch key is increased, and the wireless earphone can judge whether the wireless earphone is plugged into the box or not based on the capacitance value change of the first touch key. Therefore, the wireless earphone can determine the information of the wireless earphone entering the box only by additionally arranging the second touch key inside the charging box, so that the detection cost of the wireless earphone entering the box is reduced; and the change of the capacitance value of the first touch key can be immediately detected after the wireless earphone is placed into the charging box, so that the detection time of the earphone in the charging box is shortened.
Considering that the first touch button of staff touch and wireless earphone go into the box two kinds of circumstances and all can make the capacitance value that first touch button fed back to wireless earphone increase to some extent, considering simultaneously that the area size of second touch button influences self and stacks the capacitance value on first touch button, so this application makes it satisfy when setting up the second touch button in order to distinguish the first touch button of staff touch and wireless earphone and go into the box two kinds of circumstances: after the wireless headset is plugged into the box, the capacitance value generated when the second touch key contacts the first touch key is greater than the capacitance value generated when the human hand touches the first touch key (preferably, the two capacitance values have a significant difference, for example, the capacitance value generated when the human hand touches the first touch key is usually about 50pF, and the capacitance value generated when the second touch key contacts the first touch key can be set to 100 pF).
Based on this, this application sets up one in advance and goes into box response threshold value, and its theory of setting is: the capacitance value of the first touch key when the wireless earphone is put into the box is known to be larger than the capacitance value of the first touch key when a human hand touches the first touch key, so that a box-putting induction threshold value can be set between the two capacitance values, namely the capacitance value of the first touch key when the wireless earphone is put into the box is larger than the capacitance value of the first touch key when the human hand touches the first touch key, and whether the wireless earphone is put into the box is judged based on the setting principle. Specifically, the wireless earphone of the application firstly detects the capacitance value of the first touch key, then judges whether the capacitance value of the first touch key is larger than the set box induction threshold value, and determines that the wireless earphone enters the box when the capacitance value of the first touch key is larger than the set box induction threshold value, so that the wireless earphone can enter a charging state after determining that the wireless earphone enters the box, and the charging box can charge the wireless earphone conveniently.
The invention provides a wireless earphone in-box detection method, which is applied to a wireless earphone and comprises the following steps: detecting a capacitance value of a first touch key arranged on the surface of the wireless earphone; when the capacitance value is larger than a preset in-box induction threshold value, determining that the wireless earphone is in a box; the preset box-entering induction threshold value is set according to a second touch key which is arranged in the charging box and is grounded, and after the wireless earphone is placed in the box, the capacitance value generated when the second touch key contacts the first touch key is larger than the capacitance value generated when a human hand touches the first touch key.
This application sets up the second touch button of ground connection inside the charging box, when wireless earphone goes into the box, the second touch button can with set up in the first touch button contact on wireless earphone surface, the capacitance value that the second touch button provided can superpose on first touch button promptly, thereby increase the capacitance value of first touch button (after wireless earphone goes into the box, the capacitance value that produces when the first touch button of second touch button contact > the capacitance value that produces when touching first touch button, in order to distinguish wireless earphone and go into the box and the two kinds of circumstances of staff touch). Based on the principle, the wireless earphone box entering method and device are characterized in that the box entering induction threshold value is set in advance, and the wireless earphone box entering is determined when the capacitance value of the first touch key is larger than the set box entering induction threshold value. Therefore, the wireless earphone can determine the information of the wireless earphone entering the box only by additionally arranging the second touch key inside the charging box, so that the detection cost of the wireless earphone entering the box is reduced; and the change of the capacitance value of the first touch key can be immediately detected after the wireless earphone is placed into the charging box, so that the detection time of the earphone in the charging box is shortened.
On the basis of the above-described embodiment:
as an alternative embodiment, the process of detecting a capacitance value of a first touch key disposed on a surface of a wireless headset includes:
acquiring a driving voltage signal transmitted by a first touch key arranged on the surface of the wireless earphone;
determining a capacitance value of a first touch key corresponding to the driving voltage signal according to a preset voltage-capacitance corresponding relation; the preset voltage-capacitance corresponding relation is a corresponding relation between a driving voltage signal transmitted by the first touch key and a capacitance value of the first touch key.
Specifically, the touch principle of the first touch key of the wireless headset is as follows: the wireless earphone transmits a driving voltage signal (consisting of continuous pulse signals) to the first touch key, and when a human hand touches the first touch key, the capacitance value fed back to the wireless earphone by the first touch key is increased to some extent, so that the driving voltage signal transmitted between the wireless earphone and the first touch key is reduced by a certain value. Similarly, after the wireless earphone is placed in the box, when the second touch key contacts the first touch key, the capacitance value fed back to the wireless earphone by the first touch key is increased, so that the driving voltage signal transmitted between the wireless earphone and the first touch key is reduced by a certain value.
Based on this, the corresponding relationship between the driving voltage signal transmitted by the first touch key and the capacitance value of the first touch key (that is, the voltage-capacitance corresponding relationship, which may be specifically represented in a table form) may be set in advance, so that after the wireless headset of the present application acquires the driving voltage signal transmitted by the first touch key, the capacitance value of the first touch key corresponding to the acquired driving voltage signal is determined according to the voltage-capacitance corresponding relationship.
As an optional embodiment, the wireless headset in-box detection method further comprises:
when the wireless earphone is determined to be in the box, the Bluetooth of the wireless earphone is controlled to be closed, and the wireless earphone is controlled to enter a dormant state.
Further, consider that wireless earphone goes into the box and charges the back, wireless earphone is in idle state, namely the user does not use wireless earphone this moment, so the wireless earphone of this application is confirming self after going into the box, steerable bluetooth is closed to enter dormant state, thereby reduced wireless earphone's consumption, and then practiced thrift the energy.
As an optional embodiment, the wireless headset in-box detection method further comprises:
and when the capacitance value is not greater than the preset in-box induction threshold value, determining that the wireless earphone is out of the box.
Furthermore, after the wireless headset goes out of the box, the first touch key feeds back the capacitance value of the wireless headset to restore to the state before the wireless headset goes into the box (namely, the capacitance value of the first touch key is not greater than the preset box-entering induction threshold value), so the wireless headset of the application can determine that the wireless headset goes out of the box when the capacitance value of the first touch key is not greater than the preset box-entering induction threshold value.
Preferably, the process of determining that the wireless headset goes out of the box by itself may specifically be: the wireless earphone is not greater than a preset box-entering induction threshold value at the capacitance value of the first touch key, and the wireless earphone determines that the wireless earphone goes out of the box when the capacitance value of the first touch key detected last time is greater than the preset box-entering induction threshold value, so that the earphone box-exiting detection accuracy is improved.
In addition, the wireless headset of this application can be in the automatic bluetooth of opening of confirming oneself after going out the box to the user uses.
As an alternative embodiment, when the capacitance value is greater than the preset in-box sensing threshold value, the process of determining that the wireless headset is in the box includes:
judging whether the capacitance value is larger than a preset in-box induction threshold value or not every preset first time, and determining that the wireless earphone is in the box until the capacitance value is judged to be larger than the preset in-box induction threshold value for N times continuously; wherein N is an integer greater than 1.
Specifically, considering that when the wireless headset is not plugged into the box, the capacitance value fed back to the wireless headset by the first touch key may be increased due to a certain special factor, and even the capacitance value of the first touch key is greater than the preset box-entering induction threshold value, if the wireless headset of the present application determines that the wireless headset enters the box when the capacitance value of the first touch key is determined to be greater than the preset box-entering induction threshold value at a single time, the wireless headset may enter the box by mistake.
Based on this, the wireless earphone of this application all judges whether the capacitance value of first touch button is greater than the box response threshold value of predetermineeing into at every predetermined first time to add up the number of times of judging the capacitance value of first touch button in succession and being greater than the box response threshold value of predetermineeing into, when the number of times that adds up reaches preset number of times N (N > 1), just confirms that self has gone into the box, thereby has avoided the wireless earphone single to judge the condition that the box misjudgement appears going into, and then has improved the earphone and has gone into the accuracy that the box detected.
As an optional embodiment, the wireless headset in-box detection method further comprises:
when the capacitance value is not greater than the preset box-entering induction threshold value and the capacitance value is greater than the preset hand touch threshold value, determining that the wireless earphone is in a hand touch state; wherein the preset hand touch threshold is less than the preset box-entering induction threshold.
Further, the capacitance value of the first touch key when a human hand touches the first touch key is known, so that the human hand touch threshold value smaller than the capacitance value can be set in advance, namely the in-box sensing threshold value is larger than the capacitance value of the first touch key when the human hand touches the first touch key is larger than the set human hand touch threshold value, and whether the first touch key of the wireless earphone is touched by a user is judged based on the setting principle.
Specifically, the wireless earphone of the application continuously judges whether the capacitance value of the first touch key is larger than the preset entering box induction threshold value or not under the condition that the capacitance value of the first touch key is judged to be not larger than the preset entering box induction threshold value, and when the capacitance value of the first touch key is larger than the preset entering box induction threshold value, the first touch key is determined to be being touched by a user, namely, the wireless earphone is in a hand touch state, so that the wireless earphone can execute corresponding actions of hand touch after the wireless earphone is determined to be in the hand touch state.
As an optional embodiment, when the capacitance value is not greater than the preset boxing induction threshold value and the capacitance value is greater than the preset hand touch threshold value, the process of determining that the wireless headset is in the hand touch state includes:
when the capacitance value is not larger than the preset box-entering induction threshold value, judging whether the capacitance value is larger than the preset hand touch threshold value every other preset second time, and determining that the wireless earphone is in a hand touch state until the capacitance value is judged to be larger than the preset hand touch threshold value for M times continuously; wherein M is an integer greater than 1.
Similarly, when the wireless headset is not in a box and is not in a hand touch state, the capacitance value fed back to the wireless headset by the first touch key may be increased due to a certain special factor, and even the capacitance value of the first touch key is greater than the preset hand touch threshold value, so that if the wireless headset of the application determines that the capacitance value of the first touch key is not greater than the preset box-entering induction threshold value, the wireless headset determines that the wireless headset is in the hand touch state when the capacitance value of the first touch key is determined to be greater than the preset hand touch threshold value at a single time, and the misjudgment of the touch of the wireless headset may be caused.
Based on this, the wireless earphone of the application judges whether the capacitance value of the first touch key is larger than the preset hand touch threshold value at every preset second time under the condition that the capacitance value of the first touch key is judged to be not larger than the preset box-entering induction threshold value, accumulates the times of continuously judging whether the capacitance value of the first touch key is larger than the preset hand touch threshold value, determines that the wireless earphone is in a hand touch state when the accumulated times reach the preset times M (M is larger than 1), and executes corresponding actions of hand touch, thereby avoiding the condition that touch misjudgment occurs in single judgment of the wireless earphone, and further improving the accuracy of earphone touch detection.
Further, the first time of the present application may be set to 1000ms, the first time may be set to 20ms, and the times N and M may be set to 10 times, as shown in fig. 2:
step S110: detecting a capacitance value of a first touch key arranged on the surface of the wireless earphone;
