Detailed ways

In an existing electronic device, it usually includes a SIM card holder and a microphone, wherein the SIM card holder corresponds to a card pinhole, and when the card pin is inserted into the card pinhole, the card holder can be popped up so that the user can The SIM card is placed in the seat; the microphone corresponds to a microphone hole, which is convenient for the user of the electronic device to make a voice call.

Usually, for the sake of the beauty and overall layout of the electronic equipment, the card holder of the SIM card and the microphone can be arranged on the same side of the electronic equipment, so that the card pin hole and the microphone hole are located on the same end face of the electronic equipment. , as shown in Figure 1, the card pin hole and the microphone hole are located on the same end face of the electronic device and the distance is relatively close.

In practical applications, when the user uses the card holder in the electronic device, the card pin can be inserted into the card pin hole of the card holder. However, since the card pin hole and the microphone hole are located on the same end face of the electronic device, it is easy for the user to Insert the card pin into the microphone hole by mistake. When the user inserts the microphone hole by mistake, it will usually damage the sound guide channel of the microphone, resulting in the failure of the microphone to work normally.

In the prior art, in order to avoid the above problems, a barrier wall is usually installed at the sound guide channel of the microphone. When the user inserts the microphone hole by mistake, the barrier wall can protect the sound guide channel of the microphone to a certain extent, thereby ensuring The microphone works fine. as shown in picture 2.

Figure 2 can be a cross-sectional view along the AA' line shown in Figure 1. In Figure 2, the microphone is provided with a sub-board, a sealing silicone ring, a middle frame (face cover), a sealing PET, a sound guide channel and a retaining wall , The retaining wall can protect the sound guide channel.

However, in practical applications, when the user inserts the microphone hole by mistake, if the card holder of the SIM does not pop up, the user will often use the card pin to insert the microphone hole several times vigorously. The side wall of the sound channel is damaged, resulting in air leakage in the sound guide channel, which in turn will lead to poor sound collection effect of the microphone, or even failure, which seriously affects the user experience. In addition, when the retaining wall of the sound guide channel is pierced, it is usually necessary to replace the entire middle frame during maintenance, resulting in relatively high maintenance costs.

In order to solve the above-mentioned technical problems, the embodiment of the present invention can prompt the user after the user inserts the microphone hole by mistake and before the user vigorously inserts the microphone hole. The problem that the microphone cannot be used normally due to the damage caused by poking the microphone hole.

In order to achieve the above object, an embodiment of the present invention proposes a method for detecting incorrect insertion of a microphone hole and an electronic device, the method comprising: acquiring a sound signal collected by a microphone; performing feature extraction on the sound signal to obtain a first feature vector ; matching the first eigenvector with a predetermined second eigenvector, the second eigenvector is the eigenvector corresponding to the noise signal when it is mistakenly inserted into the microphone hole; when the first eigenvector and the second eigenvector correspond If the two eigenvectors match, it prompts that the microphone hole is wrongly inserted.

In this way, by obtaining the sound signal collected by the microphone, and performing feature extraction and matching on the sound signal, it is possible to effectively detect whether the user has inserted the microphone hole by mistake; Therefore, it is convenient for the user to stop the wrong insertion operation of the microphone hole in time based on the prompt, thereby avoiding the problem of damage to the microphone caused by the user's further wrong insertion into the microphone hole, and ensuring that the microphone can be used normally.

The technical solutions provided by various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Fig. 3 is a schematic flowchart of a method for detecting a wrong insertion of a microphone hole according to an embodiment of the present application. The method is described below.

S302: Acquire the sound signal collected by the microphone.

In S302, when the user is using the electronic device, the microphone in the electronic device may collect the sound signal in the sound guide channel of the microphone in real time, and after the sound signal is collected by the microphone, the electronic device may obtain the sound signal.

S304: Perform feature extraction on the sound signal to obtain a first feature vector.

In S304, after the electronic device acquires the sound signal collected by the microphone, it may perform feature extraction on the sound signal to obtain a feature vector in order to facilitate subsequent determination of whether the sound signal is a sound signal when a pin is mistakenly inserted into the microphone hole. Here, for the convenience of distinction, the feature vector obtained by performing feature extraction on the sound signal may be referred to as the first feature vector.

When performing feature extraction on the sound signal, the following steps can be included:

First: Preprocessing the sound signal.

When the audio signal is preprocessed, the silent part included in the audio signal can be removed, and the part containing the audio information can be retained, so as to obtain the first preprocessed signal. Wherein, the silent 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.

Secondly, the first pre-processed signal is divided into frames to obtain the second pre-processed signal.

In this embodiment, the main purpose of dividing the preprocessed sound signal into frames is to facilitate subsequent digitization of the second preprocessed signal. When the first pre-processed signal is divided into frames, the specific implementation manner may refer to the existing framing method, which will not be described in detail here.

Again, digitize the second preprocessed signal to obtain a multidimensional vector.

In this embodiment, the second preprocessing signal is digitized, which can be understood as converting each frame of waveform after framing into a multi-dimensional vector containing sound information to obtain a multi-dimensional vector corresponding to the multi-frame waveform.

Finally, feature extraction is performed on the multi-dimensional vector to obtain the first feature vector.

When performing feature extraction on multi-dimensional vectors, existing algorithms for feature extraction on multi-dimensional vectors of sounds can be used, and details will not be described here.

S306: Match the first feature vector with a predetermined second feature vector.

In S306, after the first eigenvector is obtained, the first eigenvector can be matched with a predetermined second eigenvector, wherein the second eigenvector can be understood as the corresponding sound signal when the stuck needle is mistakenly inserted into the microphone hole Feature vector. Here, for the convenience of distinction, the sound signal when the stuck pin is mistakenly inserted into the microphone hole may be called a noise signal.

In this embodiment, the second eigenvector can be pre-determined in the following manner:

First, multiple noise signals collected by the microphone when the microphone is inserted into the hole by mistake for many times are acquired.

Specifically, it is possible to simulate the operation of the card pin being inserted into the microphone hole by mistake for many times, and when simulating the wrong insertion into the microphone hole, the microphone collects the noise signal in the sound guide channel, wherein the noise signal collected by the microphone may include the card pin scratching the metal Acoustic signals on surfaces and plastic surfaces.

In this embodiment, in order to accurately determine whether the sound signal in S302 is the sound signal of a stuck needle being inserted into the microphone hole by mistake in the follow-up, when the operation of simulating the mistakenly inserted microphone hole of the stuck needle for many times, each time the stuck needle is mistakenly inserted into the microphone hole The angle and strength of insertion can vary.

Secondly, after the multiple noise signals are collected, feature extraction may be performed on the multiple noise signals to obtain feature vectors corresponding to the multiple noise signals, that is, the second feature vector described above. Wherein, when performing feature extraction on a noise signal, for a specific implementation manner, refer to the step of performing feature extraction on a sound signal recorded in S304 , which will not be repeated here.

After obtaining the second feature vector, the second feature vector can be stored in the database, so that when matching the first feature vector with the second feature vector, the first feature vector can be compared with the second feature vector stored in the database vector to match.

In this embodiment, after matching the first feature vector with the second feature vector, the matching results may include the following two types:

The first type: the first eigenvector and the second eigenvector are successfully matched;

The second type: the first eigenvector fails to match the second eigenvector.

If the matching result is the first type, it can be determined that the sound signal obtained in S302 is the sound signal when the stuck needle is inserted into the microphone hole by mistake, at this time, S308 can be executed; if the matching result is the second type, it can be determined that in S302 The acquired sound signal is not the sound signal when the stuck pin is mistakenly inserted into the microphone hole. At this time, it can be determined that the stuck pin is not mistakenly inserted into the microphone hole, and the sound signal collected by the microphone is the sound signal when the microphone is used normally.

S308: If the first feature vector matches the second feature vector, prompt that the microphone hole is incorrectly inserted.

In S308, if the first eigenvector matches the second eigenvector, it can be explained that the sound signal corresponding to the first eigenvector is the sound signal when the stuck pin is inserted into the microphone hole by mistake, that is, the user mistakenly inserted the stuck pin into the microphone hole, At this time, the user may be prompted to insert the microphone hole by mistake.

In this embodiment, when the user is prompted to insert the microphone hole by mistake, it can be realized in at least one of the following ways:

control electronic equipment vibration;

Control the electronic equipment to send out the prompt sound;

A prompt message of wrong insertion is displayed on the screen of the electronic device.

Wherein, the mistakenly inserted prompt information may be a text prompt, or an animation prompt, etc., which is not specifically limited here.

It should be understood that when the electronic device is controlled to send out the prompt sound, the prompt manner of ringing may be adopted, the prompt manner of voice may also be adopted, and other prompt sounds may also be used, which are not specifically limited here. In addition, when the prompt message of wrong insertion is displayed on the screen, the correct pin hole position can also be displayed, so that the user can insert the pin into the correct position according to the prompt.

After prompting the user to mistakenly insert the microphone hole, the user can determine that the current stuck pin is inserted into the microphone hole instead of the stuck pin hole based on the prompt, and stop the wrong insertion operation, thereby avoiding the possibility of damage to the microphone due to further wrong insertion of the user into the microphone hole question.

Optionally, in this embodiment, if the first eigenvector does not match the second eigenvector, it can be explained that the sound signal corresponding to the first eigenvector is not the sound signal when the pin is inserted into the microphone hole by mistake, but the normal use of the microphone When the sound signal is used, that is, the user does not insert the card pin into the microphone hole by mistake, and the electronic device does not need to prompt at this time.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present invention, refer to FIG. 4 . Fig. 4 is a schematic flow chart of a method for detecting misinsertion of a microphone hole according to an embodiment of the present invention, which may specifically include the following steps:
