Description

Method and device for detecting air tightness of microphone

technical field

The present disclosure relates to the field of communication technologies, and in particular to a microphone airtightness detection method and device.

Background technique

The microphone acts as a microphone on the mobile terminal, and the mobile terminal is equipped with a microphone hole for picking up the voice signal. After the voice signal enters the microphone hole, it enters the microphone through the sound pickup structure of the microphone, and the voice is received by the microphone. The signal is sent to the peer. It can be seen that the airtightness of the microphone directly determines the call quality of the mobile terminal.

In the related art, the airtightness of the microphone is detected by sounding from an external speaker. Specifically, the speaker and the microphone are separated by a certain distance (for example, 20 centimeters), and the speaker is controlled to make a sound. When the microphone hole is blocked, the mobile terminal detects the size of the sound signal received by the microphone. , the mobile terminal then detects the magnitude of the sound signal received by the microphone, and if the difference between the two detected sound signals is greater than a threshold, it indicates that the airtightness of the microphone is good. Since the airtightness of the microphone is not only related to the microphone hole, but also related to the pickup structure, and the detection method of the external speaker can only detect the airtightness of the microphone hole, not the airtightness of the pickup structure. Therefore, it is not accurate to detect the airtightness of the microphone through the external speaker.

Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

Fig. 1 is a flow chart of a method for detecting the airtightness of a microphone according to an exemplary embodiment, the method for detecting the airtightness of a microphone can be applied to a mobile terminal (for example: a smart phone, a tablet computer), and can be passed The mode of installing application on the mobile terminal or the mode of the shortcut button on the user's desktop of the mobile terminal is realized, as shown in Figure 1, the airtightness detection method of this microphone comprises the following steps:

In step 101, when an instruction for detecting the airtightness of the microphone is received, the earpiece is controlled to play a voice signal.

In one embodiment, an application for detecting the airtightness of the microphone can be installed on the mobile terminal. When the airtightness of the microphone needs to be detected, the user can open the application and input the detection instruction. The detection instruction can be letters, numbers, characters or three characters. any combination of those. Therefore, the mobile terminal can receive the detection instruction, and start the process of detecting the airtightness of the microphone.

In another embodiment, the mobile terminal can preset the voice signal locally, so that the mobile terminal can read the locally preset voice signal, and play the read voice signal through the earpiece.

Wherein, the frequency of the voice signal played by the earpiece is a preset frequency, and the preset frequency is within the frequency range of human voice. For example, the preset frequency can be set to any frequency between 300Hz and 3400Hz.

In step 102, when the microphone hole corresponding to the microphone is in a first preset state, determine the first strength of the voice signal received by the microphone.

In an embodiment, the first preset state may be the unobstructed state of the microphone hole, so the first intensity refers to the intensity of the voice signal received under the unobstructed state of the microphone hole.

In step 103, when the microphone hole is in the second preset state, determine the second strength of the voice signal received by the microphone.

In an embodiment, the second preset state may be a state that the microphone hole is blocked, so the second intensity refers to the strength of the voice signal received in the state that the microphone hole is blocked. Those skilled in the art can understand that the "first" and "second" in the first preset state and the second preset state are only used to distinguish different states, and the first preset state in the present disclosure is The second preset state is used to indicate that the microphone hole is blocked.

Wherein, in order to ensure that the microphone hole is completely blocked, a compressible sponge can be used to block the microphone hole.

It is worth noting that the voice signal collected by the microphone of the mobile terminal must first pass through the outermost microphone hole, and then pass through the internal sound pickup structure. Therefore, the airtightness of the microphone depends on the microphone hole and the pickup. The airtightness of the sound structure is related. Among them, the airtightness of the microphone hole can be detected by the voice signal played to the outside, and the voice signal played by the earpiece is usually leaked inside the mobile terminal, so the airtightness of the sound pickup structure can be detected by the voice signal leaked inside.

It should be noted that the present disclosure does not limit the execution order of step 102 and step 103, and step 102 or step 103 may be executed first.

In step 104, the airtightness of the microphone is detected based on the first intensity and the second intensity.

For the description of how to detect the airtightness of the microphone based on the first intensity and the second intensity, reference may be made to the related description of the embodiment shown in FIG. 3 below, and the present disclosure will not be described in detail here.

In this embodiment, when the mobile terminal receives the instruction for detecting the airtightness of the microphone, it can control the earpiece to play the voice signal, and then determine that the microphone has received the voice signal when the microphone hole corresponding to the microphone is in the first preset state. The first strength of the microphone, and when the microphone hole is in the second preset state, determine the second strength of the voice signal received by the microphone, and finally detect the airtightness of the microphone based on the first strength and the second strength. In addition to the airtightness of the microphone hole, the airtightness of the sound pickup structure of the microphone can be detected by the detection method of the voice signal played by the earpiece in the present disclosure, thereby improving the accuracy of the airtightness detection of the microphone. In addition, the airtightness of the microphone is detected by playing a voice signal through the earpiece instead of the sound of the external speaker. Since the purchase of an external speaker for detecting airtightness is avoided, the detection cost can be saved.

In an embodiment, the above step 104 may include:

determining an absolute value of the difference between the first intensity and the second intensity;

Based on the size relationship between the absolute value of the difference and a preset threshold, the airtightness of the microphone is detected.

In an embodiment, the above step 101 may include:

determining a distance between the microphone and the earpiece;

Finding the voice intensity corresponding to the distance from a preset list, the preset list being used to record the correspondence between the distance between the microphone and the earpiece and the voice intensity;

The earpiece is controlled to play the voice signal with the voice intensity.

In an embodiment, the above step 101 may further include:

Read the local preset voice signal;

The read voice signal is played through the earpiece.

For how to detect the airtightness of the microphone, please refer to the subsequent embodiments.

So far, the above method provided by the embodiments of the present disclosure can accurately detect the airtightness of the microphone, and can save the detection cost.

The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.

Fig. 2A is a flow chart of another method for detecting the airtightness of a microphone according to an exemplary embodiment; Fig. 2B is a schematic diagram of a microphone and an earpiece on a mobile terminal according to the embodiment shown in Fig. 2A. Embodiment Using the above method provided by the embodiment of the present disclosure, how to control the handset to play a voice signal is used as an example to illustrate, as shown in FIG. 2A, including the following steps:

In step 201, the distance between the microphone and the receiver is determined.

In one embodiment, the strength of the speech signal collected by the microphone is not only related to the strength of the speech signal itself, but also related to the distance between the microphone and the sound source. The strength of the voice signal has certain requirements. Therefore, before controlling the earpiece to play the voice signal, the distance between the microphone and the earpiece can be determined first.

Wherein, since more than one microphone is set on the mobile terminal, the mobile terminal can pre-configure the distance between each microphone and the earpiece to distinguish the position of each microphone. For example, a microphone (main microphone) is usually installed at the bottom of the mobile terminal to pick up the user’s voice when talking on the phone; on the back of the top of the mobile terminal, a microphone (auxiliary microphone) is installed near the camera to assist the main microphone to pick up the user’s voice. the sound of.

In step 202, the voice intensity corresponding to the distance is searched from a preset list, which is used to record the correspondence between the distance between the microphone and the earpiece and the voice intensity.

In an embodiment, during the detection process, in order to ensure that the intensity of the voice signal reaching each microphone hole is consistent, the mobile terminal can pre-configure a preset list for recording the distance between the microphone and the earpiece and the voice intensity. The corresponding relationship between the voice intensities corresponding to the distances recorded in the preset list can be obtained through experiments. Generally, the farther the distance is, the greater the corresponding voice intensities are.

In an exemplary scenario, as shown in FIG. 2B , the microphone 16 on the mobile terminal is the main microphone, the microphone 17 is the auxiliary microphone, the distance between the microphone 16 and the receiver 15 is D1, and the distance between the microphone 17 and the receiver 15 is D1. The distance is D2, the speech intensity corresponding to the distance D1 may be dB1, the speech intensity corresponding to the distance D2 may be dB2, and since D1>D2, therefore, dB1>dB2.

In step 203, the earpiece is controlled to play the voice signal with the voice intensity.

In an embodiment, the mobile terminal can read a locally preset voice signal, and play the voice signal through the earpiece with the voice intensity.

In another exemplary scenario, as in the scenario shown in step 202 above, if the airtightness of the main microphone is detected, the earpiece plays a voice signal with a voice intensity of dB1; if the airtightness of the secondary microphone is detected, Then the earpiece plays a voice signal with a voice intensity of dB2.

In this embodiment, since there is more than one microphone on the mobile terminal, the mobile terminal can control the voice intensity of the voice signal to be played through the distance between the microphone and the earpiece, so as to ensure that the intensity of the voice signal reaching each microphone hole is consistent, It is convenient to use the threshold to judge the airtightness of the microphone later.

Fig. 3 is a flow chart showing another airtightness detection method of a microphone according to an exemplary embodiment; this embodiment utilizes the above-mentioned method provided by the embodiment of the present disclosure to determine how to detect the microphone based on the first intensity and the second intensity The airtightness of the airtightness is taken as an example, as shown in Figure 3, including the following steps:

In step 301, the absolute value of the difference between the first intensity and the second intensity is determined.

In step 302, the airtightness of the microphone is detected based on the magnitude relationship between the absolute value of the difference and a preset threshold.

In an embodiment, if the absolute value of the difference exceeds a preset threshold, it is determined that the airtightness of the microphone is good, and if the absolute value of the difference does not exceed the preset threshold, it is determined that the airtightness of the microphone is not good.

Wherein, the preset threshold can be set according to actual experience. If it is determined that the airtightness of the microphone is good, it means that the airtightness of the corresponding microphone hole and the pickup structure are good, and if it is determined that the airtightness of the microphone is not good, it means that the airtightness of the corresponding microphone hole may not be good. Well, it may also be that the corresponding pickup structure is not airtight. It is also possible that the airtightness of the corresponding microphone hole and the pickup structure is not good.

In an exemplary scenario, the preset threshold is 150. As shown in Table 1, the first intensity and the second intensity are respectively obtained in four situations. The first case shows that the airtightness of the microphone hole is good, but the airtightness of the pickup structure is not good; the second case shows that the airtightness of the microphone hole and the pickup structure is good; the third case shows that The airtightness of the microphone hole is not good, but the airtightness of the pickup structure is good; the fourth case shows that the airtightness of both the microphone hole and the pickup structure is not good. Therefore, for the microphones in the first, third, and fourth situations, the absolute value of the difference between the second intensity and the first intensity does not exceed 150. It can be seen that the airtightness of the microphones is not good; for the microphones in the third situation , from the absolute value of the difference between the second intensity and the first intensity exceeding 150, it can be seen that the airtightness of the microphone is good. In addition, in the above-mentioned embodiment shown in FIG. 2, the voice intensity of the voice signal played by the earpiece reaching each microphone hole is consistent. For the microphone in the fourth situation, even when the microphone hole is blocked, the measured second The strength is greater than that of the first and second cases, so it can be further confirmed that the airtightness of the microphone hole and the pickup structure of the microphone in the fourth case is not good.

one two three Four first intensity 200 200 200 200 second intensity 100 0 100 150

Table 1

In this embodiment, the mobile terminal plays the voice signal through the earpiece, and uses the magnitude relationship between the absolute value of the difference between the first intensity in the first preset state and the second intensity in the second preset state and the preset threshold Judge the airtightness of the microphone. Therefore, in the present disclosure, the detection method of playing voice signals by the earpiece can not only detect the airtightness of the microphone hole, but also detect the airtightness of the sound pickup structure of the microphone, thereby improving the accuracy of airtightness detection of the microphone. In addition, the airtightness of the microphone is detected by playing a voice signal through the earpiece instead of the sound of the external speaker. Since the purchase of an external speaker for detecting airtightness is avoided, the detection cost can be saved.
