It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
At present, along with wearable equipment's development, more and more wearing formula equipment is accepted by vast consumer like intelligent bracelet, earphone, wherein, wireless earphone is because of its small and exquisite convenience, is in the favor. The wireless earphone needs a matched charging box to charge the wireless earphone due to the small size and short endurance time. The charging box needs to detect that the wireless earphone enters the box, namely, the wireless earphone and the charging box are connected, and then the charging circuit is started to charge the wireless earphone. Here, detect wireless earphone and go into the box at the box that charges, the box that charges can be automatic and wireless earphone connection, acquires the electric quantity of wireless earphone, if the electric quantity is 100%, then can not charge, if the electric quantity is less than 100%, will charge it.
Here, the manner of detecting that the wireless headset is inserted into the charging box includes: in the first mode, the wireless earphone is detected to enter the box through the exposed pin between the wireless earphone and the charging box. The exposed pins are generally 2 or 3 pins, if the exposed pins comprise two pins, one of the pins is used as a communication pin, and the other pin is used as a charging pin; if the exposed pins include three pins, 1 of the three pins is used as a communication pin, and the other 2 pins are used as charging pins. And in the second mode, an infrared sensor, a capacitance sensor, a Hall sensor and the like are additionally arranged in the charging box to detect the connection of the wireless earphone into the box.
However, in the first mode, detection circuits need to be added to the wireless headset and the charging box, and the wireless headset and the charging box both have exposed pins, which may be oxidized to reduce detection accuracy while affecting appearance. Mode two, need increase the sensor simultaneously inside wireless earphone and the box that charges, like this, be unfavorable for the design of the big electric quantity of little volume of wireless earphone promptly, also can be when wireless earphone does not go into the box that charges, because of the distance of sensor distance charging box roof when wireless earphone does not go into the box differs little with the distance of wireless earphone main part distance sensor when going into the box, leads to the false detection, reduces the accuracy that detects wireless earphone and the box that charges and be connected.
Based on this, in order to solve the above problems, an object of the detection method provided by the embodiments of the present application is to detect that a wireless headset is inserted into a box by using sound waves without exposing a pin and without adding a sensor to the wireless headset. When the wireless earphone is placed in the charging box, due to the difference of the structure of the wireless earphone, the structure of the charging box, the mode of placing the wireless earphone in the charging box and the like, specific sound is generated when the wireless earphone is placed in the charging box, and the sound has fixed Time Domain (TD) and Frequency Domain (FD). In this way, the sound of the wireless headset when being put into the box is recorded, parameters such as TD and FD are extracted, and the extracted parameters are stored in the charging box, for example, in a charging box Micro Control Unit (MCU). When detecting that the lid and the box body of box that charges open relatively, the box that charges begins to acquire the target audio frequency, when detecting that target audio frequency and the TD and the FD of prestoring are unanimous, then confirm to place in the box body with the wireless earphone that the box that charges corresponds to charge the earphone through the box that charges.
From this, effectively reduce the possibility of false detection, improve the accuracy that detects wireless earphone and the box that charges and be connected, guarantee to charge the box and charge for its wireless earphone that corresponds fast. In addition, more battery space is reserved for the design of small space and large electric quantity of the wireless earphone, meanwhile, the wireless earphone does not need to be limited to be electrified during detection, the wireless earphone does not need to be communicated with a charging box, and the portability of the design of the wireless earphone is guaranteed to the maximum extent.
Based on this, the following describes in detail the detection method provided by the embodiment of the present application through a specific embodiment and an application scenario thereof with reference to fig. 1 to fig. 2.
The embodiment of the present application provides a detection architecture, as shown in fig. 1, the detection architecture may include a charging box and an earphone including a wireless earphone 10, or may have a device configured with the charging box, such as a wearable device like a smart watch. Wherein, the charging box includes lid 101 and box body 102, and the charging box can be used for accomodating wireless earphone 10 to it charges to be less than 100% at its electric quantity.
The charging box and the wireless headset 10 described above will be described below.

The universal serial bus 20 is used for standardizing the connection and communication between the charging box and external equipment such as a charger; the overvoltage protection circuit 21 is used for protecting a subsequent circuit from being damaged by load shedding or instantaneous high voltage; the power management unit 22 is a microcontroller that controls the power functions of the digital platform; the battery 23 may charge the wireless headset 10 corresponding to the charging box; the micro control unit 25 is configured to store audio of the wireless headset 10 placed in the box body, or store audio of the wireless headset 10 placed in the box body and audio of the cover 101 and the box body 102 that are relatively closed, and detect whether a similarity between the acquired first target audio and the stored preset audio satisfies a first preset threshold, or detect whether a similarity between the acquired first target audio and the stored preset audio satisfies a first preset threshold, and detect whether a similarity between the acquired second target audio and the stored preset audio satisfies a second preset threshold. Under the condition that the similarity of the first target audio and the preset audio is detected to meet a first preset threshold value, the wireless earphone 10 corresponding to the charging box is determined to be placed in the box body 102 and connected with the wireless earphone 10, or under the condition that the similarity of the first target audio and the preset audio is detected to meet the first preset threshold value and the similarity of the second target audio and the preset audio is detected to meet a second preset threshold value, the cover body 101 and the box body 102 are determined to be relatively closed, and the wireless earphone 10 is placed in the charging box and connected with the wireless earphone 10. When the wireless earphone 10 is determined to be connected, the power management unit 22 is controlled to detect the electric quantity and charge the wireless earphone 10 through the battery 23; the led 26 may be used as a warning light to notify the user of the power information; the radio 27 is configured to pick up and transmit sound, and convert the sound signal into an electrical signal, and the radio 27 in this embodiment of the application may acquire an audio frequency of the wireless headset 10 placed in the box body 102 and an audio frequency of the cover 101 and the box body 102 that are relatively closed, and acquire a first target audio frequency (or a first target audio frequency and a second target audio frequency) when it is detected that the cover 101 and the box body 102 of the charging box are relatively opened, so that the micro control unit 25 detects whether the similarity between the first target audio frequency and the preset audio frequency meets a first preset threshold (or detects whether the similarity between the first target audio frequency and the preset audio frequency meets a first preset threshold and detects whether the similarity between the second target audio frequency and the preset audio frequency meets a second preset threshold). The Wireless headset 10 may be a Wireless bluetooth headset (TWS).
Based on the above detection architecture, the detection method provided in the embodiment of the present application may obtain the preset audio frequency of the wireless earphone 10 placed in the box body 102 through the radio 27, so that when the micro control unit 25 detects that the cover 101 and the box body 102 of the charging box are relatively opened, or detects that the wireless earphone 10 is not included in the charging box and the cover 101 and the box body 102 of the charging box are relatively opened, the radio 27 obtains the first target audio frequency; when the similarity between the first target audio and the preset audio meets the first preset threshold, the mcu25 determines that the wireless headset 10 corresponding to the charging box is placed in the box 102 and connected to the wireless headset 10. Or, the first target audio and the second target audio are acquired through the radio receiver 27; when the similarity between the first target audio and the preset audio meets the first preset threshold and the similarity between the second target audio and the preset audio meets the second preset threshold, the micro control unit 25 determines that the cover 101 and the case 102 are relatively closed, and the wireless headset 10 is placed in the charging case and connected to the wireless headset 10. Then, the mcu25 detects the power of the wireless headset 10 through the power management unit 22, and charges the wireless headset 10 through the battery 23 when the power of the wireless headset 10 is less than or equal to a preset power, such as 100%.
Therefore, on the premise that the pin is not exposed and the sensor is not added in the wireless earphone, whether the wireless earphone is placed in the charging box and connected with the charging box is detected by using the sound wave. From this, effectively reduce the possibility of false detection, improve the accuracy that detects wireless earphone and the box that charges and be connected to guarantee to charge the box and charge for its wireless earphone that corresponds fast.
It should be noted that, based on the detection architecture, an application scenario of the detection method provided in the embodiment of the present application is described. The detection method provided by the embodiment of the application can be applied to the scene that the charging box detects the wireless earphone entering the box. The method can also be applied to a scene that the electronic equipment is connected with the charger, for example, when the situation that the electric quantity of the electronic equipment is smaller than or equal to the preset electric quantity is detected, the first target audio is obtained, and when the similarity of the first target audio and the preset audio meets a first preset threshold value, the electronic equipment is determined to be connected with the charger, so that the electronic equipment can start the charging circuit to charge the electronic equipment. Based on this, the embodiment of the present application may also be used in any scenario of detecting connection of two devices, and is not limited herein.
According to the application scenario, the following describes in detail the detection method provided by the embodiment of the present application with reference to fig. 3.
Fig. 3 is a flowchart of a detection method according to an embodiment of the present application.
As shown in fig. 3, the detection method may be applied to a charging box, and specifically may include the following steps based on this:
first, in step 310, a first target audio is obtained when the cover and the case of the charging case are relatively opened. Then, in step 320, when the similarity between the first target audio and the preset audio meets a first preset threshold, determining that the earphone corresponding to the charging box is placed in the box body; and 330, charging the earphone through the charging box, wherein the preset audio is pre-stored audio of the earphone placed on the box body, and the first target audio is sound of the earphone contacting with the charging box.
The above steps are described in detail below, specifically as follows:
referring first to step 310, in one or more alternative embodiments, a first target audio is obtained upon detecting that the charging pouch does not include an earphone therein and that the cover and the case of the charging pouch are relatively open.
Here, in order to ensure that the amount of power of the charging box is reduced, the first target audio may be acquired when it is detected that the earphone is not included in the charging box and the cover and the box of the charging box are relatively opened, so as to eliminate a problem that the radio is opened to increase the amount of power consumption of the charging box when the earphone is included in the charging box.
It should be noted that, if there are two earphones, the charging box includes only one earphone, and the radio is also turned on to obtain the first target audio when the cover and the box of the charging box are relatively opened, so as to ensure the accuracy of the charging box in detecting the connection between the other earphone and the charging box.
Then, referring to step 320, in one or more alternative embodiments, before step 320, the detection method may further include:
under the condition that the earphones comprise a first earphone and a second earphone, acquiring a first audio frequency of the first earphone placed in the box body and a second audio frequency of the second earphone placed in the box body;
and determining the first audio and the second audio as preset audio.
Based on this, the step 320 may specifically include:
extracting a first target audio signal in the first target audio, wherein the first target audio signal comprises audio signals except the noise signal;
matching the first target audio signal with a first audio signal of a first audio and a second audio signal of a second audio to obtain a matching result;
when the matching result represents that the similarity between the first target audio signal and the first audio signal and the similarity between the first target audio signal and the second audio signal are greater than or equal to a first preset threshold value, the earphone corresponding to the charging box is placed in the box body.
For example, a first target audio signal other than a noise signal in the first target audio is extracted, which in one possible embodiment comprises two, namely a first sub-target audio signal and a second sub-target audio signal. Here, the time domain waveform 31 and the frequency domain waveform 32 corresponding to the first sub-target audio signal, and the time domain waveform 33 and the frequency domain waveform 34 corresponding to the second sub-target audio signal are determined.
Matching a time domain waveform 35 and a frequency domain waveform 36 corresponding to a pre-stored first audio signal and a time domain waveform 37 and a frequency domain waveform 38 corresponding to a pre-stored second audio signal with the time domain waveform 31, the frequency domain waveform 32, the time domain waveform 33 and the frequency domain waveform 34, and determining that the earphone corresponding to the charging box is placed in the box body under the condition that the time domain waveform 31 and the frequency domain waveform 32 are matched with the time domain waveform 35 and the frequency domain waveform 36 and the time domain waveform 33 and the frequency domain waveform 34 are matched with the time domain waveform 37 and the frequency domain waveform 38.
Here, it should be noted that the first audio signal may be an audio signal with a first earphone placed in the box body, or an audio signal with a second earphone placed in the box body. Therefore, if the time domain waveform and the frequency domain waveform of the first target audio signal are matched with the preset audio signal, the earphone corresponding to the charging box can be placed in the box body.
In addition, in one or more optional embodiments, the step 320 may specifically include:
under the condition that the preset audio frequency further comprises a third audio frequency with a cover body and a box body relatively closed, a second target audio frequency is obtained, and the second target audio frequency is a sound with the cover body and the box body relatively closed; and under the condition that the similarity between the second target audio signal of the second target audio and the third audio signal of the third audio is greater than or equal to a second preset threshold value, determining that the cover body and the box body are relatively closed, and placing the earphone in the charging box.
For example, similar to the earphone being put into the charging box, there may be a unique time domain waveform and a unique frequency domain waveform corresponding to the audio signal, and similarly, there may also be a special time domain waveform and a special frequency domain waveform when the cover and the box of the charging box are relatively closed. In order to promote the accuracy that detects the earphone and charge the box and be connected, can combine the earphone to put into the process that charges the box and carry out the cubic and detect that an earphone is put into the detection, another earphone is put into the lid that detects and charge the box and the relative closed detection of box body, its concrete testing process as follows:
and respectively acquiring the audio frequency put into one earphone, the audio frequency put into the other earphone and a second target audio frequency, namely the audio frequency of the charging box with the cover body and the box body relatively closed.
Then, the time domain waveform 31 and the frequency domain waveform 32 corresponding to the first sub-target audio signal of the audio put in one earphone, the time domain waveform 33 and the frequency domain waveform 34 corresponding to the second sub-target audio signal of the audio put in another earphone, the time domain waveform 39 and the frequency domain waveform 40 corresponding to the second target audio, the time domain waveform 35 and the frequency domain waveform 36 corresponding to the first audio signal of the preset audio, the time domain waveform 37 and the frequency domain waveform 38 corresponding to the pre-stored second audio signal, and the time domain waveform 41 and the frequency domain waveform 42 corresponding to the third audio signal of the pre-stored third audio are set.
And if the similarity between the three groups of corresponding first target audios and second target audios and the time domain waveforms and the frequency domain waveforms of the three groups of prestored audios meets the preset threshold values, namely a first preset threshold value and a second preset threshold value, determining that the earphones corresponding to the charging box are placed in the charging box.
It should be noted that the interval between the acquisition of the first target audio and the acquisition of the second target audio is less than or equal to the preset time period, that is, it is ensured that the one-time earphone is placed in the charging box, thereby avoiding detection errors. In addition, the detection method in the embodiment of the application does not limit the sequence of the detected audio and the acquired audio, that is, the first target audio may be acquired first and then the first target audio and the preset audio may be matched, and then the second target audio may be acquired and matched with the preset audio. Or, the first target audio and the second target audio are acquired within a preset time period, and the first target audio and the second target audio are matched with the preset audio at the same time, so that the sequence is not limited.
In addition, the detection method provided by the embodiment of the application can preset different audio frequencies according to different types of earphones, different types of charging boxes and positions of the earphones placed in the charging boxes, and is exemplified by fig. 4 to fig. 10.
The earphone a corresponding to the earphone style 1 shown in fig. 4 is placed vertically in the charging box as shown in fig. 5. Then, fig. 6 is a schematic diagram of a time domain waveform of the earphone a placed in the charging box. In addition, as for the earphone B corresponding to the earphone style 2 shown in fig. 7, the earphone B shown in fig. 8 is placed horizontally in the charging box. Then, fig. 9 is a schematic diagram of a time domain waveform of the earphone B placed in the charging box. Comparing the time domain waveform diagram shown in fig. 6 with the time domain waveform diagram shown in fig. 9, as shown in fig. 10, the upper curve is a curve corresponding to the earphone a, the lower curve is a curve corresponding to the earphone B, the frame 101 is a frequency band 2-3 KHz corresponding to the frequency domain maximum value of the earphone a, and the frame 102 is 7-9 KHz corresponding to the frequency domain maximum value of the earphone B.
As can be seen from the above examples, when the earphone is placed in the charging box, there are specific frequency domain waveforms, time domain waveforms and durations, and different earphones have different waveforms and durations due to differences in the structure of the earphone, the structure of the charging box, the placement manner, and the like. Through the detection of specific waveforms, whether the earphone corresponding to the charging box is placed in the box body or not can be determined, and the earphone is connected with the earphone.
Furthermore, in one or more alternative embodiments, after step 320, the detection method may further include: detecting the electric quantity of the earphone;
and when the electric quantity of the earphone is less than or equal to the preset electric quantity, charging the earphone.
Then, step 330 is involved, the power of the headset is detected, and when the power is less than or equal to the preset power, such as 100%, the headset is charged through the charging box.
In summary, in the embodiment of the application, the acquired first target audio and the pre-stored preset audio of the box body in which the earphones are placed are matched, and when the similarity between the first target audio and the pre-stored audio meets the first preset threshold, the earphones corresponding to the charging box are determined to be placed in the box body. Therefore, on the premise that the pins are not exposed and the sensor is not added in the earphone, whether the earphone is placed in the charging box and connected with the charging box is detected by using sound waves. From this, effectively reduce the possibility of false detection, improve the accuracy that detects the earphone and charge the box and be connected to guarantee to charge the box and charge for its earphone that corresponds fast.
In addition, more battery space is reserved for the design of small space and large electric quantity of the earphone, the earphone is not required to be limited to be powered during detection, the earphone and a charging box are not required to be communicated, and the portability of earphone design is guaranteed to the maximum extent.
It should be noted that, in the detection method provided in the embodiment of the present application, the execution subject may be a detection device, or a control module in the detection device for executing the detection method. In the embodiment of the present application, a detection device executing a detection method is taken as an example, and the detection device provided in the embodiment of the present application is described.
