detailed description

The present application provides an information processing method and electronic equipment, which are used to solve the technical problem that the best voice information cannot be obtained in the prior art.

The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

When using an electronic device including a sound collection device to collect voice information, first determine the first distance value between the first reference object and the sound collection device, and then determine the first collection parameter corresponding to the first collection parameter value of the sound collection device Whether the value matches the first distance value, wherein, if it matches, it means that under the condition of the first distance value and the first collection parameter value, the sound collection device can obtain better voice information, so no adjustment is required The first acquisition parameter; and if it does not match, it means that under the conditions of the first distance value and the first acquisition parameter value, the sound acquisition device cannot obtain better voice information, so the first acquisition parameter needs to be adjusted, and then The technical effect that the sound collection device can obtain the best voice information is achieved regardless of any adjustment of the distance between the sound collection device and the sound source.

In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

An embodiment of the present application provides an information processing method, which is applied to an electronic device including a sound collection device, such as a notebook computer, a mobile phone, a tablet computer, and the like.

As shown in Figure 2, the information processing method includes the following steps:

S201: Detect and obtain a first distance value between a reference object and a first object, wherein the distance between the sound source of the sound collected by the sound collection device and the sound collection device can be determined based on the first distance value The second distance value of ;

S202: Determine whether the first collection parameter value corresponding to the first collection parameter of the sound collection device matches the first distance value;

S203a: When the first collection parameter value does not match the first distance value, adjust the parameter value of the first collection parameter from the first collection parameter value to a second collection parameter value, wherein, The second acquisition parameter value matches the first distance value.

S203b: When the first collection parameter value matches the first distance value, use the sound collection device to collect a first sound from the sound source.

Wherein, in this step S201, as a preferred embodiment, the reference object is a sound collection device, and the first object is the object corresponding to the sound source, then the first distance value and the second distance value are the same. In another embodiment, the reference object can be the display screen of the electronic device, and the sound collection device is arranged on the host computer of the electronic device, wherein the sound collection device is 0.3M away from the display screen, and the back of the display screen of the electronic device is 0.3M. Facing the door; the first object is the door, and the sound source is located inside the room, arranged between the door and electronic equipment. The distance between the sound source and the door is 2M, and the distance between the first reference object and the first object is The first distance value, that is, the distance between the door and the host of the electronic device is 5.7M, then the second distance value can be calculated as: L=5.7M-2M+0.3M=4M. Of course, the above-mentioned embodiments only give a possibility between the first reference object and the first object, and this application does not limit what the first reference object and the first object are in the specific implementation process, as long as they can Obtaining the second distance value based on the first distance value falls within the scope of protection intended by this application.

Wherein, in step S201, a distance sensor can be used to detect the first distance value, and the distance sensor is, for example, a magnetic displacement sensor, a slip resistance displacement sensor, a laser displacement sensor, an ultrasonic ranging sensor, a visual displacement sensor, etc., for the The distance sensor and what kind of sensor are not limited in this application.

Wherein, the step S201, as shown in FIG. 3 , may further include the following steps:

S301: Obtain an environmental noise value of the environment where the sound collection device is located;

S302: Determine whether the environmental noise value is greater than a first preset threshold;

S303: Obtain the first distance value through detection when the environmental noise value is greater than the first preset threshold.

Specifically, if the noise value of the environment is less than if it is less than the first preset threshold, as an optimal embodiment, for example: when the environmental noise value is zero dB, no matter what the first distance value and the first acquisition parameter are , the sound collection device can obtain a better sound information collection effect, so for the purpose of saving energy consumption, there is no need to adjust the first collection parameter, so there is no need to collect the first distance value.

It can be seen from the above description that in the embodiment of the present application, the first distance value needs to be detected only when the environmental noise value is greater than the first preset threshold value, and then it is judged whether it is necessary to adjust the first acquisition parameter, while the environmental noise value When it is less than the first preset threshold, there is no need to detect the first distance value, and it is not necessary to adjust the first collection parameter, so the technical effect of saving energy while obtaining the best voice information is achieved.

Wherein, step S202, as shown in Figure 4, can be further divided into the following steps:

S401: Obtain a first sound pressure level corresponding to the first distance value;

S402: Determine whether the difference between the first sound pressure level and the first loudness of the ambient noise of the environment where the sound collection device is located is greater than a second preset threshold, and obtain a first determination result;

S403: Based on the first determination result, determine whether the first acquisition parameter value matches the first distance value.

Wherein, the first sound pressure level in step S401 can be calculated by using the following formula:

S=S1-20lgL

Wherein, S represents the first sound pressure level, and its unit is decibel;

S1 represents the sound pressure level at a distance of 1 meter from the sound collection device, and its unit is decibel;

L represents the second distance value, and the unit is meter.

Wherein, the sound pressure level at 1 meter represented by S1 has different values in different environments, assuming that in the current environment, the value is 80dB. And based on the difference of L, the first sound pressure level is also different. A few values are listed below to introduce them.

Second distance value L(M) The first sound pressure level S(dB) Example ① 1 80-20*lg1=80 Example ② 2 80-20*lg2=74

Example ③ 4 80-20*lg4=68

Assume that in this environment, the first loudness of the ambient noise is 50dB. Of course, in the actual implementation process, the first loudness may also be other values, such as: 40dB, 60dB, which is not limited in this application. Under normal circumstances, when the difference between the first sound pressure level and the first loudness of the ambient noise is greater than 20dB, the voice information will hardly be affected by the environmental noise, and only when it is less than 20dB will it be greatly affected. influences. Therefore, as a preferred embodiment, the second preset threshold here can be set to 20dB. Of course, in the actual implementation process, it is not limited to 20dB, but can also be 22dB, 17dB or any other value, which is not limited in this application.

When the first loudness of the ambient noise is 50dB and the second preset threshold is 20dB, the difference between the first sound pressure level and the first loudness in example ① and example ② is greater than the second preset threshold; The difference between the sound pressure level and the first loudness is less than the second preset threshold value, so the first acquisition parameter value in example ① and example ② matches the first distance value; and the first acquisition parameter value in example ③ and The first distance value does not match.

It can be seen from the above description that in the embodiment of the present application, by judging whether the difference between the first sound pressure level corresponding to the first distance value and the first loudness of the ambient noise of the environment where the sound collection device is located is greater than the second preset threshold value, It is determined whether the first acquisition parameter value matches the first distance value, and the first sound pressure level and the first loudness are easy to obtain, so there is a technical effect of convenient operation.

Wherein, in step S203a, the parameter value of the first collection parameter is adjusted from the first collection parameter value to the second collection parameter value, which may specifically include various situations, and two of them are listed below The introduction, of course, is not limited to the following two situations in the specific implementation process.

The first one is to adjust the microphone gain of the sound collection device from a first value to a second value different from the first value.

Specifically, by adjusting the gain of the microphone, the first sound pressure level corresponding to the sound source collected by the sound collection device is increased, so that the difference between the first sound pressure level and the first loudness is greater than the second preset threshold.

For example: in example ③, the original first sound pressure level is 68dB. After adjusting the gain of the microphone, the first sound pressure level may be increased to 75dB, 80dB, etc. In this case, the first sound pressure level is the same as the first sound pressure level. The loudness difference is 25dB, 30dB, which is greater than the second preset threshold.

It can be seen from the above description that in the embodiment of the present application, by adjusting the microphone gain of the sound collection device, the microphone gain can be matched with the first distance value, thereby obtaining the best voice information, and the adjustment of the microphone gain is very convenient, so There is a technical effect of ease of operation.

In the second type, the parameter value of the noise reduction parameter of the sound collection device is adjusted from a third value to a fourth value different from the third value.

Specifically, the value of the first loudness is reduced by adjusting the noise reduction coefficient of the sound collection device, so that the difference between the first sound pressure level and the first loudness is greater than the second preset threshold.

For example: in the current environment, the first loudness of the ambient noise is 50dB, and after adjusting the noise reduction coefficient of the sound collection device, the first loudness may be reduced to 46dB, 42dB, in this case, the sound pressure level and the first loudness A loudness difference is 22dB, 26dB, which is greater than the second preset threshold.

It can be seen from the above description that in the embodiment of the present application, in addition to adjusting the microphone gain of the sound collection device, the noise reduction coefficient of the sound collection device can also be adjusted, so that the technical effect of obtaining the best voice information can be further ensured.

Of course, in the specific implementation process, in order to achieve better results, the microphone gain and noise reduction coefficient of the sound collection device can also be adjusted at the same time. For the specific implementation process, the first collection parameter is one or multiple parameters , this application is not limited.

Wherein, in step S203b, since the first acquisition parameter value matches the first distance value, it means that the difference between the first sound pressure level and the first loudness is greater than the second preset threshold value. In this case, the ambient noise It has little influence on the sound collected by the sound collection device, so in this case, if the sound of the sound source is collected, better speech information can be obtained.
