Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1, an embodiment of the present invention provides a vibration optimization method, which is applied to a mobile terminal, wherein the method includes:

Step 11: When the mobile terminal is in a sounding mode, acquire a first measurement parameter of the intensity of vibration generated by the mobile terminal when sounding.

Specifically, when the mobile terminal emits sound, the strength of the vibration generated by the mobile terminal can be characterized by parameters such as displacement, velocity and acceleration. Preferably, the measurement parameter is acceleration.

As an implementation manner, the step of acquiring the first measurement parameter of the vibration intensity generated when the mobile terminal emits sound includes: acquiring the acceleration of the vibration generated by the mobile terminal when the mobile terminal emits sound collected by an acceleration sensor of the mobile terminal value; the acceleration value is used as the first measurement parameter of the vibration intensity generated when the mobile terminal emits sound.

In this embodiment, the acceleration sensor of the mobile terminal is used as the vibration sensor, and the acceleration value (the change speed of the vibration speed) when the mobile terminal vibrates is collected to represent the strength of the vibration generated by the mobile terminal, which means that the user side feels the vibration. The degree of vibration of the mobile terminal when the sound is generated to vibrate.

Step 12: When the first measurement parameter is greater than a preset threshold, attenuate a part of the audio signal generated when the mobile terminal emits sound within a preset low frequency range.

In this embodiment, the mobile terminal is preset with a plurality of filters with different attenuation intensities, which are used to attenuate the part within the preset low frequency range of the audio signal generated when the mobile terminal emits sound to different degrees. Preferably, the part within the preset low frequency range can be set to be lower than 800 Hz. When the first measurement parameter is greater than the preset threshold, which means that the user side feels that the vibration intensity of the vibration generated by the mobile terminal when the sound is produced reaches the preset state, the filter with the preset attenuation intensity is used to determine that the audio signal is in the preset low frequency range. The part within the audio signal is filtered to attenuate the part of the audio signal within the preset low frequency range, thereby reducing the intensity of the vibration generated by the mobile terminal, thereby reducing the vibration sensation on the user side.

Referring to FIG. 2 , the steps of the vibration optimization method according to another embodiment of the present invention include:

Step 21: When the mobile terminal is in a sounding mode, acquire a first measurement parameter of the intensity of vibration generated by the mobile terminal when sounding.

Specifically, when the mobile terminal emits sound, the strength of the vibration generated by the mobile terminal can be characterized by parameters such as displacement, velocity and acceleration. Preferably, the measurement parameter is acceleration.

In this embodiment, the acceleration sensor of the mobile terminal is used as the vibration sensor, and the acceleration value (the change speed of the vibration speed) when the mobile terminal vibrates is collected to represent the strength of the vibration generated by the mobile terminal, which means that the user side feels the vibration. The degree of vibration of the mobile terminal when the sound is generated to vibrate.

Step 22: Acquire a second measurement parameter of the sound loudness when the mobile terminal emits sound.

Specifically, the step of acquiring the second measurement parameter of the sound loudness when the mobile terminal emits sound includes:

Acquiring audio data collected by the microphone of the mobile terminal; determining an audio signal in the audio data generated when the mobile terminal emits sound; acquiring the audio signal strength of the audio signal as the second measurement parameter.

Wherein, the vibration amplitude of the audio signal is obtained as the audio signal strength, which represents the sound loudness (unit: decibel) when the mobile terminal emits sound.

In this embodiment, when determining the audio signal generated when the mobile terminal emits sound according to the audio data, it is detected whether the mobile terminal is in a noise scene; if the mobile terminal is in a noise scene, the mobile terminal in the audio data is extracted. Audio signal generated when sound is emitted.

Specifically, when the mobile terminal is in a noise scene, the audio data includes an audio signal generated when the mobile terminal emits sound and a noise signal in the environment where the mobile terminal is located; wherein the noise signal is the audio All audio signals in the data except the audio signals generated when the mobile terminal sounds. Detecting whether the audio data contains a noise signal; when the audio data contains the noise signal, performing analysis processing on the audio data, and extracting the audio signal generated by the mobile terminal in the audio data.

In addition, if the mobile terminal is in a noise-free environment, the audio data collected through the microphone of the mobile terminal only includes the audio signal generated when the mobile terminal makes a sound. In this way, the microphone can be directly used as a sound sensor, and the audio signal collected by the microphone can be used as the audio signal generated by the mobile terminal.

Step 23: When the measurement parameter is greater than a preset threshold, attenuate the part of the audio signal that is generated when the mobile terminal emits sound within the preset low frequency range, until the amount of change of the first measurement parameter is the same as that of the first measurement parameter. The ratio between the changes of the second measurement parameter is smaller than the preset ratio threshold.

Specifically, it can be known from the equal loudness curve that the human body's perception of loudness (audio signal strength) is relatively sensitive in the middle and high frequency parts, and relatively weak in the low frequency part. It can be seen from the equal vibration intensity curve that the human body's perception of vibration intensity is more sensitive in the low frequency part and relatively weak in the high frequency part.

In this way, when the first measurement parameter of the intensity of the vibration generated by the mobile terminal is greater than the preset threshold, it means that when the user side feels that the intensity of the vibration generated by the mobile terminal when the mobile terminal emits sound reaches the preset state, when the mobile terminal emits sound The part of the generated audio signal in the preset low frequency range is attenuated until the ratio between the variation of the first measurement parameter and the variation of the second measurement parameter is less than the preset ratio threshold to ensure that the Attenuate the part of the audio signal generated by the mobile terminal that is within the preset low frequency range, and reduce the vibration intensity of the mobile terminal when the impact on the sound loudness of the mobile terminal is small, thereby reducing the vibration on the user side. The optimal processing of vibration generated by the mobile terminal is realized.

As an implementation manner, when the first measurement parameter is greater than a preset threshold, step by step according to a predetermined attenuation intensity step, the part of the audio signal that is generated when the mobile terminal is uttered within a preset low frequency range is gradually enhanced. The intensity is attenuated until the ratio between the variation of the first measurement parameter and the variation of the second measurement parameter is less than a preset ratio threshold.

Specifically, the mobile terminal is preset with filters with different attenuation strengths, wherein the attenuation strength difference between adjacent filters with attenuation strengths is the same. In this way, when the first measurement parameter of the vibration intensity generated by the mobile terminal is greater than the preset threshold (the first measurement parameter is recorded as A1 and the second measurement parameter as B1), the preset first filter with the smallest attenuation intensity is used. The device attenuates the part in the preset low frequency range of the audio signal generated when the mobile terminal emits sound. After the attenuation process is obtained, the first measurement parameter of the vibration intensity when the mobile terminal emits sound is A2, and the second measurement parameter of the sound loudness when the mobile terminal emits sound is B2.

Detecting whether the ratio between the variation of the first measurement parameter and the variation of the second measurement parameter is less than the preset ratio threshold can be represented by the following formula (1):

Among them, P represents the preset ratio threshold.

If the formula (1) is satisfied, it means that after attenuating the part of the audio signal generated by the mobile terminal that is within the preset low frequency range, the degree of suppression of the audio signal strength (sound loudness when the mobile terminal is sounding) is guaranteed to be relatively low. In a small case, the vibration intensity generated by the mobile terminal can be optimally suppressed.

If the formula (1) is not satisfied, the part of the audio signal in the preset low frequency range is subjected to a second filter whose attenuation strength is greater than the attenuation strength corresponding to the first filter in the order of increasing the predetermined attenuation strength step size. The filtering process is performed until the condition of formula (1) is satisfied, so as to ensure that the vibration intensity generated by the mobile terminal can be optimally suppressed under the condition that the suppression degree of the audio signal intensity is small.

As another implementation manner, when the first measurement parameter is greater than a preset threshold, gradually increase the low frequency of the part within the preset low frequency range in the audio signal generated when the mobile terminal emits sound according to a predetermined frequency step range until the ratio between the variation of the first measurement parameter and the variation of the second measurement parameter is less than a preset ratio threshold.

Specifically, when the first measurement parameter of the vibration intensity generated by the mobile terminal is greater than the preset threshold (the first measurement parameter is recorded as A1 and the second measurement parameter is B1), a filter with a predetermined attenuation intensity is used to measure the mobile terminal The part in the preset low frequency range (eg lower than 800Hz) of the audio signal generated when the sound is produced is attenuated. After the attenuation process is obtained, the first measurement parameter of the vibration intensity when the mobile terminal emits sound is A2, and the second measurement parameter of the sound loudness when the mobile terminal emits sound is B2.

If the ratio between the variation of the first measurement parameter and the variation of the second measurement parameter is detected and satisfies the formula (1), it means that the audio signal generated by the mobile terminal when the sound is generated is within the preset low frequency range. After attenuation, the vibration intensity generated by the mobile terminal can be optimally suppressed under the condition that the suppression degree of the audio signal intensity is ensured to be small.

If it is detected that the ratio between the change amount of the first measurement parameter and the change amount of the second measurement parameter does not satisfy the formula (1), increase the frequency within the preset low frequency range in the audio signal according to the predetermined frequency step. The low frequency range of the part of the frequency range, and use a filter with a predetermined attenuation strength to attenuate the part in the preset low frequency range (for example: lower than 820Hz) after adjusting the step size in the audio signal generated when the mobile terminal emits sound, until it satisfies Condition of formula (1), so as to ensure that the vibration intensity generated by the mobile terminal can be optimally suppressed under the condition that the suppression degree of the audio signal intensity is small.

It should be noted that, the setting range and the specific numerical value of the frequency step of the audio signal in the audio signal in the preset low frequency range in the above-mentioned embodiments are only exemplary, and the present invention is not limited thereto.
