[0030] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0031] With the development of wireless communication technology, the application of wireless headphones with intelligent and wireless trends is becoming more and more widespread. Among them, True Wireless Stereo (TWS) Bluetooth headphones are a typical type of wireless headphones. TWS headphones consist of two parts: headphones and headphone boxes. Usually, the charging box needs to detect the entry of the headphones in time, then charge the headphones, and perform a series of information interactions.

[0032] At present, most earphone boxes require additional sensors, such as: Hall switch detection, acceleration sensor detection, light sensor detection, etc. There is even a method of detecting using the principle of capacitance and current to determine whether the earphones are in the box.

[0033] However, the above detection method has the following problems:

[0034] 1. Hall principle detection is currently the more mainstream detection method. This method is relatively reliable, but it requires additional Hall switches and additional magnets in the box. The design is complex and the cost is high.

[0035] 2. Due to the principle of light sensitivity changes, it is easy to misjudge scenes such as occlusion, resulting in a poor user experience.

[0036] 3. The acceleration sensing principle has a difficult tolerance for false triggering and can easily lead to misjudgment in some scenarios, resulting in a poor user experience.

[0037] 4. Capacitor-current principle, circuit design is more complicated and the cost is higher.

[0038] In view of this, the embodiment of the present disclosure provides a method for detecting earphones entering a box. In the method, no additional sensors or noise signals are required. The method only needs to use the microphone MIC in the earphone to pick up the sound and combine the algorithm to determine whether the earphones are in the box. The method for detecting earphones entering a box provided in the embodiment of the present disclosure not only achieves a simple design and low cost, but also has a relatively simple algorithm control.

[0039] Figure 1 is a flow chart of a method for detecting earphones entering a box according to an exemplary embodiment. Figure 1 As shown, the earphone entry detection method is used in TWS earphones and includes the following steps.

[0040] In step S101, a sound signal picked up by an earphone is acquired.

[0041] In step S102, if it is determined that the sound signal matches the sound signal preset in the earphone, it is determined that the earphone is in the box-entered state.

[0042] In one embodiment of the present disclosure, the pre-set sound signal includes at least one of the following: a sound signal determined based on the collision between the earphone and the earphone box, a sound signal of knocking on the earphone box, and a sound signal of the user issuing a target instruction. For the convenience of subsequent description, the various embodiments of the present disclosure are mainly described by taking the sound signal determined based on the collision between the earphone and the earphone box as an example. It is understandable that the sound signal picked up by the earphone in the earphone box detection method provided in the present disclosure is not limited to this.

[0043] In one embodiment of the present disclosure, a sound signal picked up by a target microphone is obtained, wherein the target microphone includes: a microphone whose power consumption during data processing is lower than a threshold.

[0044] In another embodiment of the present disclosure, a sound signal picked up by a target microphone in a headset is obtained. The target microphone may be a smart microphone (SmartMIC). In addition, the power consumption of the target microphone during data processing is lower than a threshold, such as a smart microphone with processing capability of a low-power digital signal processing (DSP) chip.

[0045] In one embodiment of the present disclosure, the sound signal can be picked up and the algorithm can be processed by a DSP chip. The sound signal can be picked up by a target microphone with a DSP chip in the headset, and the picked up sound signal can be processed according to the DSP chip. When the processed sound signal matches the sound signal pre-set in the headset, it can be determined that the headset is in the box state.

[0046] In one embodiment of the present disclosure, the collision sound refers to the collision noise signal generated by the accelerated contact between the magnet at the head of the wireless headset and the magnet set in the headset box, which is an instantaneous sound. The sound is used to detect the box entry operation. In particular, this noise signal is very obvious in terms of time, so that it can be clearly distinguished from other noises in terms of the loudness of the sound signal, the size of the sound signal, the frequency of the sound signal, etc. There are obvious characteristics to compare with other noises.

[0047] In one embodiment of the present disclosure, the noise signal may be understood as a signal generated by different objects, which is a useless sound signal for human ears.

[0048] However, currently, in order to use acoustics to detect whether the earphones are in the box, a speaker needs to be added to the earphone box. When the earphone box is closed, it is opened, which proves that the user wants to put the wireless earphones in the earphone box, and the earphone box starts the speaker installed in the earphone box. A certain preset audio signal is continuously played through the speaker. When the wireless earphones are put into the earphone box, the audio signal emitted by the earphone box is obtained through the microphone of the earphone, and then compared with the preset audio signal in the earphone. If the audio signal emitted by the earphone box is the same as the preset audio signal in the earphone, it is determined that the wireless earphone has completed the box insertion operation. In this way, a speaker needs to be separately set in the earphone box, which is not only costly and complicated in terms of process, but also requires the addition of additional noise signals, which greatly reduces the user experience.

[0049] In the headphone box detection method of the disclosed embodiment, there is no need to set additional noise signals through the headphone box, and only the target microphone of the wireless headphone needs to pick up the collision sound signal between the wireless headphone and the headphone box or the sound signal of knocking on the headphone box, the sound signal of the user issuing a target instruction, etc. The sound signal picked up by the microphone of the headphone is compared with the sound signal pre-set in the wireless headphone to determine whether the wireless headphone is in the box state.

[0050] It is understandable that the sound signal pre-set in the embodiment of the present disclosure is a signal that can be obtained without improving the structure of the earphone box.

[0051] Among them, the collision sound signal picked up by the target microphone of the wireless headset is compared with the preset signal. The sound signal preset in the wireless headset is an experimental value, which is obtained by colliding the wireless headset with the headset box many times. The sound after the collision obtained after many experiments is very stable, and the sound signal after the collision obtained has obvious characteristics. Figure 2As shown, from the time domain, it can be seen that the sound signal determined by the collision between the wireless headset and the headphone box has obvious characteristics, which can be distinguished from the noise signals in other scenes, and the consistency is very good. Whether it is through algorithm adjustment or machine learning, it is easy to achieve the detection of the headset entering the box by this collision signal. Therefore, the sound after the collision can be used as the pre-set sound of the wireless headset, and compared one by one with the sound signal picked up by the target microphone of the wireless headset. When the sound signal received by the target microphone of the wireless headset has the same characteristics as the sound signal pre-set by the wireless headset, the wireless headset can be judged as the box entry operation. If the sound signal does not match the pre-set sound signal in the headset, the headset is not in the box state.

[0052] Through the above embodiment, it is only necessary to detect the earphones entering the box through the principle of acoustic detection, without adding additional sensors or additional noise signals, which realizes a simple design, low cost, and relatively simple algorithm control. The sound signal determined for the earphones and earphone boxes with the same serial number is single, and therefore the method of detecting the earphones entering the box has high reliability.

[0053] Figure 3 is a flowchart showing a method of determining that a wireless headset is in a box-entered state if a sound signal matches a sound signal preset in the wireless headset according to an exemplary embodiment, such as Figure 3 As shown, the following steps are included.

[0054] In step S201, in response to detecting that the attribute of the sound signal meets the preset attribute condition.

[0055] In step S202, it is determined that the sound signal matches a sound signal preset in the earphone.

[0056] In an embodiment of the present disclosure, the attribute includes at least one of the following: duration, loudness, and frequency.

[0057] In one embodiment of the present disclosure, the encoded information obtained by decoding the sound signal includes: pitch, timbre, and loudness. Any complex sound can be described by these three attributes, which correspond to three physical quantities of sound pressure: frequency, phase, and amplitude.

[0058] In one embodiment of the present disclosure, the coding information of the sound signal can be divided into the time domain and the frequency domain. Among them, in the algorithm for detecting whether the earphone is in the box, the specific implementation process is: from the time domain, the duration of the sound and the loudness of the sound, where the loudness of the sound can also be understood as the amplitude spanned by the sound signal, are all the biggest features in the time domain. From the frequency domain, the earphone continuously picks up different sounds from a certain frequency to a certain frequency through the target microphone, and the frequency span is different.

[0059] In one embodiment of the present disclosure, the serial number of the earphone box is consistent with the serial number of the wireless earphone based on the collision between the wireless earphone and the earphone box.

[0060] For example, when the serial number of the earphone box is consistent with the serial number of the wireless earphone, the wireless earphone and the matching earphone box are made of the same material, such as material A. Furthermore, when the earphone made of material A collides with an object made of material B, or collides with an object made of material C or other objects made of material A that are not matched with the wireless earphone, the frequencies of the sounds of the earphone colliding with objects of different materials picked up by the target microphone of the earphone are different. In other words, in the earphone box detection method provided by the present invention, the frequency corresponding to the pre-set sound signal determined based on the sound of the wireless earphone colliding with the matching earphone box is unique. The frequency characteristic mainly determines the pitch of the sound.

[0061] In one embodiment of the present disclosure, the pre-set sound signal has a tolerance, and the tolerance range is relatively wide. In the production process of earphones and earphone boxes, there may be production tolerances, and therefore, the collision sounds of different earphones and their respective matching earphone boxes picked up multiple times may be different. For example, the duration, amplitude and frequency of the collision sound signals of individual earphones may vary to a certain extent. Therefore, the present disclosure sets a reasonable tolerance range for the pre-set sound signal to lock the sound signals generated by the collisions between different earphones and their respective matching earphone boxes.

[0062] In another embodiment of the present disclosure, the preset sound signal is an experimental value, which is set in the following two ways: First, a segment of audio signal is measured through a large amount of experimental data, and then the collision sound generated by the earphone and the earphone box is identified according to the self-learning method. Second, the upper and lower limits are set, and the threshold is set relatively broadly. As long as the time and height corresponding to the picked-up sound signal are within the range of this threshold, the sound signal can be considered to be the collision sound generated by the earphone and the earphone box. Among them, the upper and lower limits are set by the algorithm, and the algorithm goes through a continuous self-learning stage, which helps to improve the recognition efficiency, and the probability of false detection and missed detection is small.

[0063] In the current technology, only when the sound signal picked up by the microphone is basically consistent with the preset sound signal, can it be judged that the earphone is in the box, and there is no misjudgment, misoperation, etc., and the noise signal picked up by the microphone is an additional audio signal. The earphone box detection method provided by the present disclosure needs to match the sound signal picked up by the earphone microphone, detect the duration, amplitude and other characteristics of the picked up sound signal, and after the sound signal is converted into frequency, it is within the tolerance range of the preset sound signal, so that it can be judged in real time that the earphone has been put into the earphone box.

[0064] Through the embodiments provided by the present disclosure, the acoustic recording device MIC inside the earphone can be fully utilized without the need for additional sensors, which can effectively save the stacking space inside the earphone. In addition, since the present disclosure saves additional sensor modules, it can save the cost of developing additional modules for the project and reduce the complexity of assembly production.

[0065] Figure 4 is a flow chart of a method for detecting earphones entering a box according to an exemplary embodiment. Figure 4 As shown, the following steps are included.

[0066] In step S301, it is detected that the attribute of the sound signal meets the preset attribute condition.

[0067] The specific implementation of step S301 can be found in Figure 3 The specific implementation of step S201 will not be explained here.

[0068] In step S302, the sound signal is decoded to obtain coding information of the sound signal.

[0069] In step S303, if the coding information matches the target coding information, it is determined that the sound signal matches the sound signal preset in the earphone.

[0070] In an embodiment of the present disclosure, the preset sound signal is obtained by encoding the target encoding information.

[0071] In one embodiment of the present disclosure, it is determined whether the encoding information obtained by decoding the sound signal matches the target encoding information. Since the preset sound signal is obtained by encoding the sound signal according to the target encoding information, the earphone pre-stores the target encoding information and the preset sound signal obtained by encoding based on the target encoding information.

[0072] In one embodiment of the present disclosure, after the wireless headset obtains the sound signal, the sound signal is decoded. If the obtained coding information does not contain the target coding information, it is determined that the sound signal is not a sound signal for box entry detection. If the obtained coding information contains coding information, it can be determined whether the sound signal is used for box entry detection by judging whether the coding information matches the target coding information.

[0073] In one embodiment of the present disclosure, after detecting that the attribute of the sound signal meets the preset attribute condition, the sound signal is decoded to obtain the corresponding coding information, and then the coding information is compared with the target coding information to see whether it matches. If the coding information matches the target coding information, it is determined that the sound signal matches the sound signal preset in the headset.

[0074] In another embodiment of the present disclosure, the DSP chip can be used to decode the sound signal picked up by the target microphone and encode the target coding information to obtain a preset sound signal. Not only is the implementation method simple, but the cost is low and the recognition reliability is high.

[0075] In yet another embodiment of the present disclosure, a usage state of the wireless headset is determined, where the usage state includes a wearing state and a non-wearing state.

[0076] In one embodiment of the present disclosure, after the target microphone in the earphone acquires an audio signal, the picked-up sound signal needs to be processed. When the user takes the earphone off the ear, the earphone picks up the sound signal generated by the surrounding environment. For example, when the user is wearing the earphone, the earphone accidentally hits the earphone against a table or wall. At this moment, the sound of the earphone colliding with other objects will be generated. The earphone will also pick up the sound signal and compare it with the pre-set sound signal. When the sound signal generated by the collision between the earphone and other objects other than the earphone box is detected to be different from the pre-set sound signal, such as the duration of the sound signal, the amplitude and other factors do not match.

[0077] In the above embodiment, since the wireless earphone and the earphone box are matching products, the materials and structures between the two are fixed, so the frequency of the collision sound generated by the wireless earphone and the earphone box is also fixed. The present disclosure provides a method for detecting whether the earphone is in the box, without adding additional noise signals, and only needs to use the collision sound generated by the wireless earphone and the earphone box as a basis for determining whether the earphone is in the box.

[0078] Figure 5 is a flow chart of a method for detecting earphones entering a box according to an exemplary embodiment. Figure 5 As shown, the following steps are included.

[0079] In step S401, it is determined that the earphone is in a box-inserted state, and an inserting operation is performed.

[0080] In step S402, in response to the earphone establishing a charging connection with the earphone box, a charging request is sent to the earphone box.

[0081] In one embodiment of the present disclosure, the charging request is used to request the earphone box to charge the earphone.

[0082] In one embodiment of the present disclosure, for example, there is an earphone box and a wireless Bluetooth headset. The earphone box is in an open state. During the process of opening the earphone box, the earphone box enters a working state. During the process of taking the wireless Bluetooth headset off the user's ear, it is equivalent to being in a working state, and the target microphone inside the wireless Bluetooth headset is also in a powered-on state. When the user puts the wireless Bluetooth headset into the earphone box, due to the mutual attraction between the magnets between the headset and the earphone box, an impact sound, such as a "pop", is generated, and its duration is short, about a few milliseconds.

[0083] In one embodiment of the present disclosure, the earphone picks up the impact sound generated by the internal target microphone, wherein the earphone is still powered on at this time. When the impact sound picked up by the target microphone is compared with the preset sound signal, if the preset sound signal is satisfied, it can be proved that the earphone is in the earphone box.

[0084] In one embodiment of the present disclosure, the earphone establishes a charging connection with the earphone box, and the connection can be established by contacting the contact point at the bottom of the earphone with the charging magnetic needle in the earphone box. On this basis, the earphone box can be informed of the fact that the earphone has entered the earphone box through the charging contact piece in the earphone box for charging the earphone, and the earphone box supplies power to the earphone, and the earphone is in a shutdown state.

[0085] In another embodiment of the present disclosure, a charging connection is established between the earphone and the earphone box, which is convenient for reminding the earphone box that the earphone is in the box and stopping the power-on state of the earphone, that is, disconnecting the connection between the earphone and the connected device, and powering the earphone through the earphone box, which can reduce the power consumption of the earphone and avoid unnecessary power consumption.

[0086] In one embodiment of the present disclosure, by collecting a large amount of experimental data, the wireless headset continuously optimizes the tolerance of the preset sound signal through self-learning, such as the loudness, timbre, etc. The timbre can reflect the resonant frequency, that is, the different proportions of harmonic components when the headset collides with objects of different materials, resulting in different sounds.

[0087] Among them, in another embodiment of the present disclosure, the self-learning process can be understood as a product update and iteration process. Contemporary headphones can pre-set a tolerance for sound signals, detect misjudgment data in the feedback data, such as data collected before the headphones are turned off, and modify the pre-set tolerance for sound signals based on the data, so as to reduce misjudgment in the next generation of products and improve the user experience.

[0088] In one embodiment of the present disclosure, the process of earphone self-learning can be self-learning by the earphone itself during use, but the continuous self-learning process will consume a lot of power consumption of the earphone. Therefore, with regard to the self-learning process, the embodiment of the present disclosure is more inclined to complete the self-learning process before the product leaves the factory. In other words, the tolerance of the sound signal of the contemporary earphone is set by self-learning with a large amount of data from the previous generation. After leaving the factory, the preset sound signal in the earphone remains unchanged. Through continuous updating and iteration, the existence of errors is continuously reduced.

[0089] In one embodiment of the present disclosure, the left and right wireless earphones do not affect each other, and there is no interaction between them. For example, when it is detected that the earphone entering the earphone box is a wireless earphone for the left ear, the contact chip of the wireless earphone for the left ear can inform the earphone box that the state of the wireless earphone for the left ear is not worn and is in the box state, after which the wireless earphone for the left ear stops working, and the earphone box supplies power to the wireless earphone for the left ear. However, in this process, the wireless earphone for the right ear is not affected.

[0090] Based on the same concept, an embodiment of the present disclosure also provides a device for detecting whether an earphone has entered a box.

[0091] It is understandable that in order to realize the above functions, the earphone box detection device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0093] The acquisition unit 101 is used to acquire the sound signal picked up by the earphone.

[0094] The processing unit 102 is used to determine that the earphone is in the box-inserted state and perform the box-insertion operation if it is determined that the sound signal matches a preset sound signal in the earphone, and the preset sound signal is a sound signal determined based on the collision between the earphone and the earphone box.

[0095] In one implementation, the acquisition unit 101 is used to acquire a sound signal picked up by a target microphone, wherein the target microphone includes: a microphone whose power consumption during data processing is lower than a threshold.

[0097] In one embodiment, the processing unit 102 is also used to decode the sound signal to obtain the encoding information of the sound signal after detecting that the attributes of the sound signal meet the preset attribute conditions; if the encoding information matches the target encoding information, it is determined that the sound signal matches the sound signal preset in the headset, and the preset sound signal is encoded for the target encoding information.

[0098] In one embodiment, the processing unit 102 is further used to determine that the earphone is in a box-inserted state, and after performing the box-inserting operation, in response to the earphone establishing a charging connection with the earphone box, send a charging request to the earphone box, wherein the charging request is used to request the earphone box to charge the earphone.

[0099] In one embodiment, the preset sound signal includes at least one of the following: a sound signal determined based on a collision between the earphone and the earphone box; a sound signal of knocking on the earphone box; a sound signal of a user issuing a target instruction.

[0100] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0101] Figure 7 1 is a block diagram of an apparatus 200 for detecting earphone in-box according to an exemplary embodiment. For example, the apparatus 200 may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.
