Description

Technical Field

[0001] The present invention relates to the technical field of music frequency adjustment, and in particular to an EQ frequency adaptive adjustment method, device, equipment and storage medium. Background Art

[0002] In the current audio products, users usually need to adjust the EQ frequency value for a better experience. The EQ frequency is a specific frequency point on the equalizer. Different EQ frequency points will have different effects on the sound: Low frequency band (usually around 20Hz-250Hz): mainly affects the strength and fullness of the sound. Increasing the low frequency can make the sound thicker and more powerful, such as enhancing the sound of drums and bass; reducing the low frequency can make the sound clearer and avoid turbidity. Mid-low frequency band (around 250Hz-500Hz): This frequency band affects the warmth and presence of the sound. Proper increase can make the sound fuller, while reduction may make the sound appear thin. Mid-frequency band (around 500Hz-2kHz): plays an important role in the clarity and intelligibility of the sound. Improving the mid-frequency band can make the sound more prominent, for example, the human voice is more obvious in this frequency band; improper adjustment may make the sound harsh or dull.

[0003] Mid-high frequency band (around 2kHz-5kHz): affects the brightness and layering of the sound. Increasing the mid-high frequency can make the sound crisper and more penetrating; too much may produce a sharp feeling. High frequency band (around 5kHz-20kHz): determines the airiness and details of the sound. Increasing the high frequency can increase the luster and sense of space of the sound, but too high will cause the sound to be harsh.

[0004] In audio processing, different EQ frequencies can be adjusted as needed to achieve the desired sound effect. For example, in music production, the EQ frequency can be adjusted to highlight the sound of a specific instrument or to improve the deficiencies in a recording; in a sound system, EQ can also be used to adapt to different room acoustic environments and personal preferences.

[0005] However, currently, the audio system cannot adaptively adjust the corresponding EQ frequency value in real time according to the sound effect category of the current song by adopting a fixed adjustment, manual adjustment or semi-automatic adjustment method of the EQ frequency value.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0061] The purpose of the embodiments of the present application is to propose an EQ frequency adaptive adjustment method, device, equipment and storage medium to solve the problem that the existing Bluetooth speakers cannot adaptively adjust the corresponding EQ frequency value in real time according to the sound effect category of the current song.

[0062] An EQ frequency adaptive adjustment method, such as Figure 1 , Figure 1 A schematic diagram of a specific implementation of an EQ frequency adaptive adjustment method in the present invention; comprising:

[0063] S100, constructing a music database, wherein the music type, the preset EQ frequency, and the range of the first three-axis change value of the three-axis accelerometer in the music database correspond to each other, and the EQ gain in the music database and the range of the second three-axis change value of the three-axis accelerometer correspond to each other.

[0064] Different types of songs have different frequency distributions. For example, rock songs usually have strong low-frequency rhythms and high-frequency guitar solos, so it is necessary to enhance the strength of the low frequency and the brightness of the high frequency. Classical music may focus on the balance of each frequency band to show the rich timbre and layering of the instruments. The vocal part of pop songs is usually more prominent in the mid-frequency band, so it is necessary to appropriately enhance the mid-frequency band to highlight the singer's voice.

[0065] In this embodiment, building a database of music types, preset EQ frequency points, and ranges of three-axis variation values ​​is beneficial for selecting preset ED frequency points according to music types. By analyzing the three-axis variation values ​​corresponding to the sound wave characteristics of the played music, the music type point to which it belongs is identified, and then the EQ frequency point is automatically adjusted to achieve the best auditory effect.

[0066] S200, using a three-axis accelerometer to detect the music sound waves of the current music emitted by the audio generator, and obtaining the third three-axis change value of the three-axis accelerometer for the music sound waves.

[0067] In a preferred embodiment, Figure 2 , Figure 2 for Figure 1 A schematic diagram of a specific implementation of S200 in the figure; S200 includes: S210, respectively obtaining the X-axis acceleration change value, Y-axis acceleration change value, and Z-axis acceleration change value of the three-axis accelerometer; S220, obtaining a third three-axis change value according to the X-axis acceleration change value, the Y-axis acceleration change value, and the Z-axis acceleration change value.

[0068] In this embodiment, when the adjusting device is fixed, the angles between the three axes of the three-axis accelerometer and the propagation direction of the sound wave can be made equal. When the music sound waves propagate toward the three-axis accelerometer of the adjusting device, the acceleration of the accelerometer in the X-axis direction, Y-axis direction, and Z-axis direction will change. The stronger the sound wave, the greater the change value.

[0069] It is worth noting that when the adjustment device is fixed, the angles between the three axes of the three-axis accelerometer and the propagation direction of the sound wave can be made unequal or partially equal, thereby setting the corresponding acceleration change value range.

[0070] S300: Determine the music type of the current music by comparing the third three-axis change value of the music sound wave with the range of the first three-axis change value in the music database.

[0071] In a preferred embodiment, Figure 3 , Figure 3 for Figure 1 A schematic diagram of a specific implementation method after S300 in the figure; S300 includes: S310, comparing the X-axis acceleration change value, Y-axis acceleration change value, and Z-axis acceleration change value of the third three-axis change value with the first X-axis acceleration change value range, the first Y-axis acceleration change value range, and the first Z-axis acceleration change value range respectively; S320, if the X-axis acceleration change value, the Y-axis acceleration change value, and the Z-axis acceleration change value all fall within the first X-axis acceleration change value range, the first Y-axis acceleration change value range, and the first Z-axis acceleration change value range, then determining that the music type corresponding to the range of the first three-axis change value is the music type of the currently playing music.

[0072] The first X-axis acceleration change value range, the first Y-axis acceleration change value range, and the first Z-axis acceleration change value range may be the same and divided into multiple levels, each level corresponding to a music type.

[0073] When determining the type of music, the acceleration change value of each frequency band can be detected based on the characteristics that, for example, rock songs usually have a strong low-frequency rhythm, the frequency bands of classical music are relatively balanced, and the frequency bands of pop songs are more prominent.

[0074] Since the included angles are equal, the three-axis acceleration change values ​​generated by the same sound wave are basically the same, and the same change range is set for judgment.

[0075] S400: Detect the music sound wave in real time using a three-axis accelerometer to obtain a fourth three-axis change value, and determine an EQ gain of the real-time frequency of the music sound wave according to the fourth three-axis change value.

[0076] In some preferred embodiments, Figure 4 , Figure 4 for Figure 1 A schematic diagram of a specific implementation scheme of S400 in the figure; S400 includes: S410, comparing the X-axis acceleration change value, Y-axis acceleration change value, and Z-axis acceleration change value of the fourth three-axis change value with the second X-axis acceleration change value range, the second Y-axis acceleration change value range, and the second Z-axis acceleration change value range respectively; S420, if the X-axis acceleration change value, the Y-axis acceleration change value, and the Z-axis acceleration change value all fall within the second X-axis acceleration change value range, the second Y-axis acceleration change value range, and the second Z-axis acceleration change value range, then determining that the EQ gain corresponding to the range of the second three-axis change value is the current EQ gain of the currently playing music.

[0077] Although the preset EQ frequency points can be adaptively selected, the best playback effect may not be achieved in different environments. For example, if the acoustic characteristics of the room cause certain frequencies of sound to be excessively absorbed or reflected, the playback effect will be compromised even if the preset EQ frequency points corresponding to the type of music are selected. For another example, in a relatively large and spacious room, the low-frequency sound may be insufficient due to the large space.

[0078] In this embodiment, by utilizing the constructed EQ gain and the range of the second three-axis change value of the three-axis accelerometer, the EQ gain of the low frequency band is automatically increased according to the real-time three-axis change value, making the bass fuller and more powerful.

[0079] S500, adaptively adjusts the EQ frequency according to the music type, and adjusts the EQ playback gain according to the real-time frequency EQ gain to obtain the desired sound effect.

[0080] The ranges of the first three-axis change values ​​include: a first X-axis acceleration change value range, a first Y-axis acceleration change value range, and a first Z-axis acceleration change value range;

[0081] The ranges of the second three-axis change values ​​include: a second X-axis acceleration change value range, a second Y-axis acceleration change value range, and a second Z-axis acceleration change value range.

[0082] In some preferred embodiments, Figure 5 , Figure 5 for Figure 1 A schematic diagram of a specific implementation of S500 in the figure; S500 includes: S510, obtaining the music type and the corresponding preset EQ frequency point; S520, playing the preset EQ frequency point as the EQ frequency point of the currently playing music.

[0083] Further, such as Figure 6 , Figure 6 for Figure 5 A schematic diagram of a specific implementation after S520 in the figure; S500 also includes: S530, comparing the current EQ gain with the preset threshold; S540, if the current EQ gain is less than the preset threshold, increasing the current EQ gain by a specified value. By building a music database, the music sound waves and the EQ gain of the real-time frequency of the currently playing music are detected in real time, the preset EQ frequency points are selected according to the music type, and the EQ gain is judged. When it is less than the specified threshold, it is strengthened. This greatly improves the music effect of the audio playback and the user experience, and solves the problem that the existing Bluetooth audio cannot adaptively adjust the corresponding EQ frequency point value in real time according to the sound effect category of the current song.
