Fig. 3 is a flowchart illustrating a method for detecting a mis-insertion of a microphone hole according to an embodiment of the present application. The method is as follows.
S302: a sound signal collected by a microphone is acquired.
In S302, during the use of the electronic device by the user, a microphone in the electronic device may acquire a sound signal in a microphone guide channel in real time, and after the microphone acquires the sound signal, the electronic device may acquire the sound signal.
S304: and extracting the characteristics of the sound signals to obtain a first characteristic vector.
In S304, after acquiring the sound signal collected by the microphone, the electronic device may perform feature extraction on the sound signal to obtain a feature vector, so as to facilitate subsequent determination of whether the sound signal is a sound signal when the card pin is inserted into the microphone hole by mistake. For the convenience of distinction, the feature vector obtained by feature extraction of the sound signal may be referred to as a first feature vector.
When the feature extraction is performed on the sound signal, the following steps may be included:
firstly: the sound signal is pre-processed.
In the preprocessing of the sound signal, a mute portion included in the sound signal may be removed, and a portion where the sound information remains, thereby obtaining a first preprocessed signal. Wherein, the mute part of the sound signal is usually located at the beginning and the end of the sound signal, and the part with sound information is usually located in the middle of the sound signal.
And secondly, framing the first preprocessed signal to obtain a second preprocessed signal.
The main purpose of framing the preprocessed sound signal in this embodiment is to facilitate the subsequent digitization of the second preprocessed signal. When the first preprocessed signal is framed, specific implementation manners can be referred to in the existing framing method, and detailed description is omitted here.
And thirdly, performing digital processing on the second preprocessed signal to obtain a multi-dimensional vector.
In this embodiment, the second preprocessing signal is digitized, which can be understood as converting each frame of waveform after framing into a multidimensional vector containing sound information, so as to obtain a multidimensional vector corresponding to the multi-frame waveform.
And finally, extracting the features of the multi-dimensional vector to obtain a first feature vector.
When the feature extraction is performed on the multi-dimensional vector, the feature extraction can be performed by using an existing algorithm for performing feature extraction on the multi-dimensional vector of the sound, which is not described in detail herein.
S306: and matching the first feature vector with a predetermined second feature vector.
In S306, after obtaining the first feature vector, the first feature vector may be matched with a predetermined second feature vector, where the second feature vector may be understood as a feature vector corresponding to the sound signal when the card pin is inserted into the microphone hole by mistake. For the sake of convenience of distinction, the sound signal when the card pin is erroneously inserted into the microphone hole may be referred to as a noise signal.
In this embodiment, the second feature vector may be obtained by determining in advance in the following manner:
first, a plurality of noise signals collected by the microphone when the microphone hole is inserted by mistake a plurality of times are acquired.
Specifically, the operation of mistakenly inserting the card pin into the microphone hole can be simulated for multiple times, and when the mistaken inserting into the microphone hole is simulated, the microphone collects the noise signals in the sound guide channel, wherein the noise signals collected by the microphone can comprise sound signals of scraping of the card pin on a metal surface and plastic surfaces.
In this embodiment, in order to accurately determine whether the sound signal in S302 is the sound signal of the card pin inserted into the microphone hole in the following process, when the operation of inserting the card pin into the microphone hole is simulated for multiple times, the angle and force of the card pin inserted in the microphone hole may be different each time.
Then, after acquiring the plurality of noise signals, feature extraction may be performed on the plurality of noise signals to obtain feature vectors corresponding to the plurality of noise signals, that is, the second feature vector described above. When extracting the features of the noise signal, the specific implementation manner may refer to the step of extracting the features of the sound signal described in S304, and a description thereof is not repeated here.
After the second feature vector is obtained, the second feature vector may be stored in a database, so that when the first feature vector is matched with the second feature vector, the first feature vector may be matched with the second feature vector stored in the database.
In this embodiment, after the first feature vector and the second feature vector are matched, the matching result may include the following two types:
the first method comprises the following steps: the first feature vector and the second feature vector are successfully matched;
and the second method comprises the following steps: the first feature vector and the second feature vector fail to match.
If the matching result is the first type, it may be determined that the sound signal acquired in S302 is a sound signal when the card pin is inserted into the microphone hole by mistake, and at this time, S308 may be executed; if the matching result is the second type, it may be determined that the sound signal acquired in S302 is not a sound signal when the card pin is inserted into the microphone hole by mistake, and at this time, it may be determined that the card pin is not inserted into the microphone hole by mistake, and the sound signal collected by the microphone is a sound signal when the microphone is normally used.
S308: and prompting the microphone hole to be inserted wrongly under the condition that the first feature vector is matched with the second feature vector.
In S308, if the first feature vector is matched with the second feature vector, it can be stated that the sound signal corresponding to the first feature vector is a sound signal when the card pin is inserted into the microphone hole by mistake, that is, the user may mistakenly insert the card pin into the microphone hole, and at this time, the user may be prompted to mistakenly insert the card pin into the microphone hole.
In this embodiment, when the user is prompted to mistakenly insert the microphone hole, the method may be implemented by at least one of the following methods:
controlling the electronic equipment to vibrate;
controlling the electronic equipment to send out prompt tones;
and displaying the prompt information of the misinsertion on a screen of the electronic equipment.
The prompt information for the misinsertion may be a text prompt, an animation prompt, or the like, and is not limited in this respect.
It should be understood that when the electronic device is controlled to emit the prompt sound, a ring prompt mode may be adopted, a voice prompt mode may also be adopted, and other prompt sounds may also be adopted, which are not specifically limited herein. In addition, when the prompt message of the misinsertion is displayed on the screen, the correct position of the card needle hole can be displayed, so that a user can insert the card needle into the correct position according to the prompt.
After prompting the user to insert the microphone hole by mistake, the user can determine that the current card pin is inserted into the microphone hole and not into the card pin hole based on the prompt, and stop the error insertion operation, so that the problem that the microphone is damaged due to the fact that the user further inserts the microphone hole by mistake can be avoided.
Optionally, in this embodiment, if the first feature vector is not matched with the second feature vector, it may be stated that the sound signal corresponding to the first feature vector is not a sound signal when the card pin is inserted into the microphone hole by mistake, but a sound signal when the microphone is normally used, that is, the user does not insert the card pin into the microphone hole by mistake, and at this time, the electronic device may not need to prompt.
For facilitating understanding of the technical solution provided by the embodiment of the present invention, refer to fig. 4. Fig. 4 is a schematic flow chart of a method for detecting a mis-insertion of a microphone hole according to an embodiment of the present invention, which may specifically include the following steps:

S402: and performing feature extraction on the sound signal to obtain a first feature vector.
When the feature extraction is carried out on the sound signal, the method comprises the following steps: preprocessing a sound signal, and removing a mute part included in the sound signal to obtain a first preprocessed signal; framing the first preprocessed signal to obtain a second preprocessed signal; carrying out digital processing on the second preprocessed signal to obtain a multidimensional vector; and performing feature extraction on the multi-dimensional vector to obtain a first feature vector.
The specific implementation of this step can be referred to the specific implementation of the corresponding step in the embodiment shown in fig. 3, and the description is not repeated here.
