detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

At present, with the development of wearable devices, more and more wearable devices such as smart bracelets and earphones such as wireless earphones are accepted by consumers. Among them, wireless earphones are popular because of their small size and convenience. Due to their small size and relatively short battery life, wireless earphones need a matching charging box to charge them. The charging box needs to detect that the wireless headset is in the box, that is, after the two are connected, the charging circuit will be turned on to charge the wireless headset. Here, when the charging box detects that the wireless headset is in the box, the charging box will automatically connect to the wireless headset to obtain the power of the wireless headset. If the power is 100%, it will not be charged. If the power is less than 100%, it will be checked. Charge.

Here, the way for the charging box to detect the entry of the wireless earphone into the box includes: Method 1, the wireless earphone and the charging box use exposed pins to detect the entry of the wireless earphone into the box. Among them, the exposed pins are generally 2 or 3 pins. If the exposed pins include two, one of them is used as a communication pin and the other is used as a charging pin; if the exposed pins include three , one of them is used as a communication pin, and the other 2 pins are used for charging. Method 2: Add infrared sensors, capacitive sensors, Hall sensors, etc. to the charging box to detect the connection of the wireless earphones into the box.

However, in the first method, a detection circuit needs to be added to the wireless earphone and the charging box, and both the wireless earphone and the charging box have exposed pins. While affecting the appearance, the pins will be oxidized and the detection accuracy will be reduced. Method 2, it is necessary to add sensors inside the wireless earphone and the charging box at the same time, so that it is not conducive to the design of the wireless earphone with a small volume and large power, and when the wireless earphone is not in the charging box, the sensor The distance from the top plate of the charging box is not much different from the distance between the earphone body and the sensor when the wireless earphones are put into the box, which leads to false detection and reduces the accuracy of detecting the connection between the wireless earphones and the charging box.

Based on this, in view of the above-mentioned problems, the purpose of the detection method provided by the embodiment of the present application is to use sound waves to detect the entry of the wireless earphone into the box without exposing pins and adding sensors to the wireless earphone. Among them, when the wireless earphone is put into the charging box in the embodiment of the present application, due to the differences in the structure of the wireless earphone, the structure of the charging box, and the way the wireless earphone is placed in the charging box, there will be a specific sound when the wireless earphone is put into the box. There are fixed time domain waveforms (Timedomain, TD) and frequency domain waveforms (Frequency domain, FD). In this way, first record the sound of the wireless earphone when it is put into the box, extract parameters such as TD and FD, and store them in the charging box, such as in the charging box Microcontroller unit (MCU). When it is detected that the lid and the box of the charging box are relatively open, the charging box starts to acquire the target audio, and when the target audio is detected to be consistent with the pre-stored TD and FD, it is determined that the wireless earphone corresponding to the charging box is placed in the box , and charge the headset through the charging box.

Thus, the possibility of false detection is effectively reduced, the accuracy of detecting the connection between the wireless earphone and the charging box is improved, and the charging box is ensured to quickly charge its corresponding wireless earphone. In addition, it also leaves more battery space for the small space and large power design of the wireless earphones. At the same time, it is not necessary to limit the power of the wireless earphones during detection, and there is no need for the wireless earphones to communicate with the charging box. Lightweight wireless headset design.

When the similarity between the detected first target audio and the preset audio satisfies the first preset threshold, it is determined that the wireless earphone 10 corresponding to the charging box is placed in the box body 102 and connected to the wireless earphone 10, or, upon detection When the similarity between the first target audio and the preset audio satisfies the first preset threshold, and it is detected that the similarity between the second target audio and the preset audio meets the second preset threshold, it is determined that the cover 101 and the box 102 are relatively Closed, and the wireless earphone 10 is placed in the charging box and connected with the wireless earphone 10 . When it is determined to be connected with the wireless earphone 10, the power management unit 22 is controlled to detect the electric quantity, and the wireless earphone 10 is charged by the battery 23; the light-emitting diode 26 can be used as a reminder lamp to prompt the electric quantity information for the user; the radio 27 is used for picking up and To transmit sound, the sound signal can be converted into an electrical signal, and the receiver 27 in the embodiment of the present application can obtain the audio of the wireless earphone 10 being placed in the box body 102 and the audio of the relative closure of the cover body 101 and the box body 102, and detect When the cover 101 and the box body 102 of the charging box are relatively opened, the first target audio (or the first target audio and the second target audio) is obtained, so that the micro control unit 25 detects the first target audio and the preset audio Whether the similarity of the first target audio meets the first preset threshold (or detects whether the similarity of the first target audio and the preset audio meets the first preset threshold and detects whether the similarity of the second target audio and the preset audio meets the second preset threshold). The wireless headset 10 may be a wireless Bluetooth headset (True Wireless Stereo, TWS).

Or, obtain the first target audio and the second target audio through the microphone 27; the micro-control unit 25 meets the first preset threshold when the similarity between the first target audio and the preset audio, and the second target audio and the preset audio When the similarity meets the second preset threshold, it is determined that the cover body 101 and the box body 102 are relatively closed, and the wireless earphone 10 is placed in the charging box and connected to the wireless earphone 10 . Then, the micro control unit 25 detects the power of the wireless earphone 10 through the power management unit 22, and charges the wireless earphone 10 through the battery 23 when the power of the wireless earphone 10 is less than or equal to a preset power such as 100%.

Therefore, the possibility of false detection is effectively reduced, and the accuracy of detecting the connection between the wireless earphone and the charging box is improved, so as to ensure that the charging box quickly charges its corresponding wireless earphone.

It should be noted that based on the detection framework, the application scenario of the detection method provided in the embodiment of the present application will be described. Wherein, the detection method processing provided in the embodiment of the present application can be applied to the above-mentioned scene where the charging box detects the entry of the wireless earphone into the box. It can also be applied to the scene where the electronic device detects that it is connected to the charger. For example, when it is detected that the power of the electronic device is less than or equal to the preset power, the first target audio is obtained, and the similarity between the first target audio and the preset audio satisfies the first When a preset threshold is reached, it is determined that the electronic device is connected to the charger, so that the electronic device turns on the charging circuit to charge the electronic device. Based on this, the embodiment of the present application can also be used in any scenario of detecting the connection of two devices, which is not limited here.

According to the above application scenario, the detection method provided by the embodiment of the present application will be described in detail below with reference to FIG. 3 .

FIG. 3 is a flow chart of a detection method provided by an embodiment of the present application.

As shown in Figure 3, the detection method can be applied to the charging box, based on this, it can specifically include the following steps:

First, in step 310, the first target audio is acquired when the cover and the box of the charging box are relatively open. Then, in step 320, when the similarity between the first target audio and the preset audio satisfies the first preset threshold, it is determined that the earphone corresponding to the charging box is placed in the box; in step 330, the earphone is charged through the charging box, wherein the preset Assume that the audio is the pre-stored audio of the earphones placed in the box, and the first target audio is the sound of the earphones touching the charging box.

The above steps are described in detail below, as follows:

First, it involves step 310. In one or more optional embodiments, when it is detected that the charging box does not include an earphone, and the cover and box of the charging box are relatively opened, the first target audio is acquired.

Here, in order to reduce the power of the charging box, it is possible to obtain the first target audio when it is detected that the charging box does not include earphones, and the cover and box body of the charging box are relatively open, so as to exclude the case where the earphones are included in the charging box. Turn on the radio to increase the power consumption of the charging case.

It should be noted that if there are two earphones, only one earphone is included in the charging box, and when the cover and box body of the charging box are relatively open, the receiver should also be turned on to obtain the first target audio to ensure that the charging box Check the accuracy of another headset connected to it.

Then, step 320 is involved. In one or more optional embodiments, before step 320, the detection method may also include:

In the case where the earphone includes a first earphone and a second earphone, acquire the first audio of the first earphone placed in the box and the second audio of the second earphone placed in the box;

The first audio and the second audio are determined as preset audio.

Based on this, the step 320 may specifically include:

Extracting the first target audio signal in the first target audio, the first target audio signal includes audio signals other than noise signals;

Matching the first target audio signal with the first audio signal of the first audio and the second audio signal of the second audio to obtain a matching result;

When the matching result indicates that the similarity between the first target audio signal and the first audio signal and the second audio signal is greater than or equal to a first preset threshold, it is determined that the earphone corresponding to the charging box is placed in the box.

For example, to extract the first target audio signal except the noise signal in the first target audio, the first target audio signal includes two in a possible embodiment, namely the first sub-target audio signal and the 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 frequency-domain waveform 34 corresponding to the second sub-target audio signal are determined.

The time domain waveform 35 and the frequency domain waveform 36 corresponding to the prestored first audio signal, and the time domain waveform 37 and the frequency domain waveform 38 corresponding to the prestored second audio signal, and the time domain waveform 31, the frequency domain waveform 32, the time domain waveform Domain waveform 33 and frequency domain waveform 34 are matched, time domain waveform 31 and frequency domain waveform 32 are matched with time domain waveform 35 and frequency domain waveform 36, and time domain waveform 33 and frequency domain waveform 34 are matched with time domain waveform 37 and frequency domain waveform If the domain waveform 38 matches, it is determined that the earphone corresponding to the charging box is placed in the box.

Here, it should be noted that the first audio signal may be an audio signal of the first earphone placed in the box, or an audio signal of the second earphone placed in the box. Thus, as long as the time-domain waveform and frequency-domain waveform of the first target audio signal are matched with the preset audio signal, it can be determined that the earphone corresponding to the charging box is placed in the box.

In addition, in one or more optional embodiments, this step 320 may specifically include:

In the case that the preset audio also includes the third audio of the relative closure of the lid and the box body, the second target audio is obtained, and the second target audio is the sound of the relative closure of the lid and the box body; When the similarity between the target audio signal and the third audio signal of the third audio is greater than or equal to the second preset threshold, it is determined that the cover and the box are relatively closed, and the earphone is placed in the charging box.

For example, similar to putting the earphones into the charging box, there will be a time-domain waveform and a frequency-domain waveform corresponding to the unique audio signal. Similarly, when the lid and the box body of the charging box are relatively closed, there will also be a special time-domain waveform. and frequency domain waveforms. In order to improve the accuracy of detecting the connection between the earphone and the charging box, three tests can be performed in combination with the process of putting the earphone into the charging box, that is, one earphone is put in for detection, the other earphone is put in for detection, and the cover and box of the charging box are relatively closed The specific detection process is as follows:

Acquire the audio input from one earphone, the audio input from the other earphone, and the audio of the second target audio, that is, the relatively closed lid and box body of the charging box.

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 by an earphone, and the time-domain waveform 33 and the corresponding time-domain waveform 33 of the second sub-target audio signal of the audio put in by another earphone The frequency domain waveform 34 and 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 its preset audio, and the prestored second audio signal corresponding to The time domain waveform 37 and the frequency domain waveform 38, and the time domain waveform 41 and the frequency domain waveform 42 corresponding to the prestored third audio signal of the third audio.

If the similarity between the first target audio and the second target audio corresponding to the three groups and the time-domain waveform and the frequency-domain waveform of the three pre-stored audio groups meet the preset threshold, that is, the first preset threshold and the second preset threshold, then determine The earphones corresponding to the charging box are placed in the charging box.

It should be noted that the interval between acquiring the first target audio and the second target audio should be less than or equal to the preset time period, that is, to ensure that the earphone is put into the charging box for one time, so as to avoid detection errors. In addition, the detection method in the embodiment of the present application does not limit the order of audio detection and audio acquisition, that is, the first target audio can be obtained first, and then the first target audio and the preset audio can be matched, and then the second target audio can be obtained. And match the second target audio with the preset audio. Alternatively, 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, and the sequence thereof is not limited here.

In addition, the detection method provided by the embodiment of the present application may vary according to different types of earphones, different types of charging boxes, and the positions where the earphones are placed in the charging box.

The earphone A corresponding to the earphone style 1 shown in Figure 4, and the earphone A shown in Figure 5 are placed vertically in the charging box. Then, FIG. 6 is a schematic diagram of time-domain waveforms when earphone A is put into the charging box. In addition, the earphone B corresponding to the earphone style 2 shown in FIG. 7 is placed horizontally in the charging box as shown in FIG. 8 . Then, FIG. 9 is a schematic diagram of time-domain waveforms when earphone B is put into the charging box. Compare the time-domain waveform schematic diagram shown in Figure 6 with the time-domain waveform schematic diagram shown in Figure 9, as shown in Figure 10, the upper curve is the curve corresponding to earphone A, and the lower curve is the curve corresponding to earphone B, box 101 is the frequency band 2-3 KHz corresponding to the maximum value of the frequency domain of the earphone A, and box 102 is 7-9 KHz corresponding to the maximum value of the frequency domain of the earphone B.

From the above examples, it can be seen that when the earphones are placed in the charging box, there are specific frequency domain waveforms, time domain waveforms, and duration. waveform and duration. Through the detection of specific waveforms, it can be determined whether the earphone corresponding to the charging box is placed in the box and connected to the earphone.

In addition, in one or more optional embodiments, after step 320, the detection method may further include: detecting the power of the earphone;

When the power of the headset is less than or equal to the preset power, the headset is charged.

Then, step 330 is involved, detecting the power of the earphone, and charging the earphone through the charging box when the power is less than or equal to a preset power such as 100%.

To sum up, in the embodiment of the present application, by matching the acquired first target audio with the pre-stored preset audio of the earphone placed in the box, the similarity between the first target audio and the preset audio satisfies the first When the threshold is preset, it is determined that the earphone corresponding to the charging box is placed in the box. In this way, on the premise of not exposing pins and adding sensors to the earphone, the sound wave is used to detect whether the earphone is placed in the charging box and connected to it. As a result, the possibility of false detection is effectively reduced, and the accuracy of detecting the connection between the earphone and the charging box is improved, so as to ensure that the charging box quickly charges its corresponding earphone.

In addition, it also leaves more battery space for the small space and large power design of the earphones. At the same time, it is not necessary to limit the power of the earphones during detection, and it is not necessary for the earphones to communicate with the charging box, which ensures the earphone design to the greatest extent. Portability.
