[0002] Headphones have been widely used in people's daily life and work. The increasingly higher quality of life has prompted people to pursue better music enjoyment. In addition to the music itself, headphones and speakers with various functions and quality effects are emerging in an endless stream. Not only do they use better speakers and better cavity designs to achieve better sound quality, but they also adjust the equalizer (EQ, equalize) according to different needs to balance the timbre of each frequency band.

[0003] The human ear perceives sound frequencies from the lowest 20Hz to the highest 20KHz, while the human voice frequency range is concentrated between 80Hz and 12kHz. People feel different sounds in different frequency bands. At present, headphone manufacturers have adjusted the equalizer control parameters for each frequency band when the headphones leave the factory to produce different gain effects, so that users can hear better sound effects through the headphones. However, this design also has defects. The EQ gain of current headphones is generally set at the factory. All headphones are standardized for sound calibration to achieve a unified listening effect. This creates a problem. The EQ set for the headphones at the factory is universal and suitable for all people, but different users have different hearing effects for each sound band. For example, a user has a stronger perception of the sound in the 60Hz--250Hz frequency band, and a weaker perception of the sound in the 250Hz--4KHz frequency band. The existing EQ setting method is obviously unable to adapt to different users and cannot achieve the best listening effect. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0029] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0030] See also Figure 1A and Figure 1B , Figure 1A and Figure 1B Schematic diagram of application scenarios of the equalizer adjustment method based on auricle scanning provided in an embodiment of the present invention. The equalizer adjustment method based on auricle scanning is applied to earphone 20 or smart phone 10. The earphone 20 or smart phone 10 is provided with a scanner, and the scanner is configured to scan the auricle of the user. Among them, there are many types of scanners, such as infrared scanning modules and laser scanning modules, which are not limited here. There can also be many types of earphones 20, such as headphones 20, TWS headphones 20, Bluetooth headphones 20, etc., which are not limited here. When the ear-picking headset 20 is detected, a scanner can be provided on the earmuff of the headset 20 to facilitate scanning the user's ears. In other embodiments, the scanner can be an independent device specifically used to scan the user's ears, and the scanner is connected to the earphone 20 or smart phone 10 for communication, and the scanner transmits the scanned auricle morphology to the earphone 20 or smart phone 10 through a wired or wireless transmission method.

[0031] First of all, it should be explained that an equalizer (hereinafter referred to as EQ) is an electronic device that can adjust the amplification of various frequency components of electrical signals separately. It can compensate for the defects of speakers and sound fields, compensate and modify various sound sources and have other special functions by adjusting electrical signals of different frequencies. Generally, the equalizer on the mixing console can only adjust the three frequency bands of high frequency, medium frequency and low frequency electrical signals separately. In the communication system, inserting an equalizer in the baseband system can reduce the impact of inter-symbol interference.

[0032] The auricle of each individual is different. Generally speaking, normal EQ is suitable for all people. However, there are some problems. Different auricles have different sensitivities in different sound frequency bands. Some people may have abnormally high sensitivity in one frequency band and abnormally low sensitivity in another frequency band. This problem can be solved by this embodiment.

[0033] Figure 2 1 is a flow chart of an equalizer adjustment method based on auricle scanning provided by an embodiment of the present invention. As shown in the figure, the method includes the following steps S110-S140.

[0034] S110, scanning the user's auricle to obtain the corresponding auricle shape.

[0035] In one embodiment, the user refers to a user who uses headphones or smart phones. The scanning method can be infrared scanning, laser scanning, or camera scanning, which is not limited in this embodiment. Correspondingly, when the infrared scanning method is adopted, the scanner is an infrared module; when the laser scanning is adopted, the scanner is a laser module. The auricle is a part of the outer ear and is a device for collecting sound waves. Most of it is supported by elastic cartilage and covered with skin. The auricle morphology refers to the contour shape of the auricle. Among them, the laser scanning method for obtaining the auricle morphology is first to emit a laser beam to scan the entire auricle of the user, reflect the reflected beam back, and obtain an image with a different arrangement order, and use the image drop to reflect the image. Of course, it can be understood that other scanning methods can also be used, such as recording the coordinates of the laser reflection point (laser emission angle and distance), and calculating the auricle morphology based on the coordinates. Of course, the infrared scanning method can also be used to obtain the auricle morphology, such as the following embodiments.

[0036] In one embodiment, if Figure 3 As shown, the step S110 may include steps: S111-S113.

[0037] S111, measuring distances at different positions including at least in front of the ear, behind the ear, above the auricle, below the auricle, and to the side of the auricle to obtain point cloud data;

[0038] S112, performing point cloud registration and fusion based on the point cloud data to obtain the auricle shape.

[0039] In one embodiment, if Figure 4As shown, the front and back of the ear refer to the front and back of the auricle, with point A and point B in the figure; the upper and lower auricle refer to the upper part of the auricle and the lower part of the auricle, that is, point C and point D on the way, and the lateral position of the auricle is the area of ​​the angle between the ear and the head, that is, point E in the figure. The measurement includes at least the positions of the front of the ear, the back of the ear, the upper auricle, the lower auricle and the side of the auricle. These positions can cover the entire auricle in all directions, which can improve the efficiency and accuracy of modeling. Of course, it is understandable that more positions can be measured. In reverse engineering, the point data set of the product appearance surface obtained by the measuring instrument is also called a point cloud. The point cloud data of this embodiment refers to the coordinate set of each measurement position, such as the set of coordinates of the above-mentioned points A, B, C, and D. There are many ways to measure distance, such as time of flight method, triangulation ranging method, structured light method and moiré fringe method, etc. As long as the distance of each position can be measured, this embodiment does not limit the measurement method. Exemplary, such as time of flight, an infrared sensor emits an infrared detection beam to each of the above-mentioned positions. After the infrared detection beam reaches each of the above-mentioned positions, it is reflected back, and the flight time T of the infrared detection beam is recorded. Then, the distance of each position is calculated according to the formula D=CT / 2, where D is the distance, C is the speed of light, and T is the flight time. After obtaining the distance of each position, the coordinates of each measurement point can be determined. The coordinates are expressed as (X, Y, Z). The coordinates are determined based on the coordinates (X, Y) of the infrared sensor. Z is the distance of the test point, which is equivalent to the depth value. The set of coordinates of all test points is represented as point cloud data. After obtaining the point cloud data, point cloud registration and fusion are performed to perform three-dimensional reconstruction of the auricle to restore the appearance of the auricle. Point cloud registration includes coarse registration and fine registration. Coarse registration refers to the registration of point clouds when the relative posture of the point clouds is completely unknown, which can provide a good initial value for fine registration. Specifically, registration algorithms based on exhaustive search (such as RANSAC registration algorithm, four-point consistent set registration algorithm, Super4PCS algorithm) and registration algorithms based on feature matching (SAC-IA based on point FPFH features, FGR algorithm, AO algorithm based on point SHOT features, ILC algorithm based on line features) can be used, which is not limited in this embodiment. Fine registration is to minimize the spatial position difference of the point cloud bracket on the basis of coarse registration. Specifically, ICP and various variants of ICP can be used, such as robust ICP, poin to plane ICP, poin to line ICP, MBICP, GICP, NICP, etc., which are not limited in this embodiment. The specific calculation process is well known to those skilled in the art and will not be described in detail here. After the point cloud data is registered and fused, the user's auricle shape is finally obtained.

[0040] In one embodiment, referring to Figure 5, the equalizer adjustment method based on auricle scanning of this embodiment is applied to headphones. The headphones include a bracket 21 and earmuffs 22 connected to both ends of the bracket 21, and the scanner is an array infrared sensor 23, the array infrared sensor 23 is arranged on the earmuffs 22, and is distributed in an array along the edge of the earmuffs 22 to adapt to scanning the user's auricle, wherein the earmuffs 22 can rotate relative to the bracket 21. The figure shows that four array infrared sensors 23 are provided, and the four infrared sensors 23 are evenly distributed on the edges of the contour of the earmuffs 22 to match various positions of the auricle. Of course, it can be understood that the number of infrared sensors 23 can also be other numbers, such as 8, 12, etc., which are not limited here. In other embodiments, the display arrangement of the infrared sensors 23 can also be arranged according to the general shape of the auricle to better adapt to the test point. The earmuff 22 of this embodiment can rotate relative to the bracket 21, for example, it can rotate in pitch relative to the bracket 21, and it can also rotate in yaw relative to the bracket 21. Specifically, a universal joint connection structure can be used to connect the earmuff 22 to the bracket 21 to achieve rotation at two angles of pitch and yaw. Of course, it can be understood that other connection structures can also be used, which are not limited here. The rotatable earmuff 22 is used in this embodiment to enable the array infrared sensor 23 to follow the rotation of the earmuff 22 to increase the scanning angle (similar to the scanning mirror of the laser radar). The purpose of expanding the scanning range can be achieved by rotating the earmuff 22. There is no need to build in a rotatable scanning part. The same effect can be achieved by relying on the rotatable earmuff 22, and the purpose of large-scale scanning is achieved in a low-cost manner. In addition, arranging the array infrared sensor 23 on the earmuff 22 can facilitate the user to scan the auricle through the earmuff 22. The user only needs to wear the headset on the head and then slightly rotate the earmuff 22 to complete the scanning of the auricle. The operation is simple and convenient. Moreover, compared with a single scanner which requires multiple scans to form an image, the array-type infrared sensor 23 can form an image in one scan, and the imaging efficiency is higher.

[0041] In other embodiments, the equalizer adjustment method based on auricle scanning of this embodiment is applied to a smart phone, and the scanner is a camera module on the smart phone, for example, it can be a color camera, it can also be a depth of field camera, or a combination of the two. When scanning, aim the camera of the smart phone at the ear, and scan around the entire ear to measure the distance of each position. Of course, it is understandable that the scanner can also be an infrared sensor on a smart phone, and the infrared sensor is used to realize the distance measurement of each position of the auricle.

[0042] In one embodiment, when scanning the ear to measure the distance of each position point of the auricle, it is also necessary to perform a simple scan inside the ear hole to optimize the entire ear shape, thereby obtaining a more complete auricle shape, making the auricle shape clearer, and improving the matching efficiency and accuracy.

[0043] S120, matching the auricle shape with a preset auricle shape to determine a target auricle shape.

[0044] In one embodiment, the preset auricle shape refers to a number of pre-set standard auricle shapes, which are simplified by countless auricles or are equivalent to several preset auricle shapes, and the corresponding EQ is adapted for each auricle shape. The EQ corresponding to these standard auricle shapes can be obtained through a model algorithm, or can be set by professional musicians corresponding to the standard auricle shapes, which is not limited here. Specifically, the preset auricle shape is pre-stored in a database. After the user's auricle shape is scanned, the user's auricle shape is matched one by one with the preset auricle shape in the database, and the preset auricle shape that is most similar to the user's auricle shape is used as the target auricle shape. Among them, the matching of the user's auricle shape and the preset auricle shape can be calculated using a similarity algorithm to obtain the similarity between the two. When the similarity between the two is greater than a threshold, the preset auricle shape is determined to be the target auricle shape.

[0045] S130. Obtain preset equalizer parameters corresponding to the target auricle shape.

[0046] In one embodiment, the above embodiment has described the EQ (preset equalizer parameters) corresponding to each auricle shape adaptation. The EQ corresponding to these standard auricle shapes can be obtained through a model algorithm, or can be set by a professional musician corresponding to the standard auricle shape, which is not limited here. The preset equalizer parameters have a one-to-one mapping relationship with the preset auricle shape and are stored in a database. After the target auricle shape is determined, the preset equalizer parameters corresponding to the target auricle shape are obtained from the database.

[0047] S140: Adjust the current equalizer according to the preset equalizer parameters.

[0048] In one embodiment, the equalizer generally includes a plurality of types of sound effect modules, for example, pop, dance, blues, classical, electronic music, rock, country, ACG, bass, heavy bass, treble, live, heavy metal, national style, folk song, rap, recording studio, etc. Each sound effect module corresponds to a plurality of frequency bands, for example, including 31, 63, 125, 250, 500, 1k, 2k, 4k, 8k, 16k Hz, etc., and each frequency band is represented by a gain digital db, for example, 3db, -5db. Each sound effect module is represented by a plurality of gain values ​​of a plurality of frequency bands. The preset equalizer parameters of this embodiment can be adapted to a set of EQ corresponding to each sound effect module setting (that is, the preset equalizer parameters include a plurality of EQ sets, each set of EQ corresponds to a sound effect module), or it can be a set of personalized EQ. When the preset equalizer parameters are a set of personalized EQ, the current equalizer can be directly set to the EQ. When the preset equalizer parameters are a set of EQ corresponding to each sound effect module setting, adjustment is performed according to the following embodiment.

[0049] In one embodiment, if Figure 6 As shown, the step S140 may include steps: S141-S143.

[0050] S141. Obtain the sound effect module corresponding to the current equalizer.

[0051] S142. Obtain corresponding frequency band adjustment parameters from the preset equalizer parameters according to the sound effect module, wherein the preset equalizer parameters include frequency band adjustment parameters corresponding to each of the sound effect modules.

[0052] S143: increase and / or decrease the value of each frequency band in the sound effect module according to the frequency band adjustment parameter.

[0053] In this embodiment, the sound effect module corresponding to the current equalizer is first obtained. For example, if the current sound effect module is popular, the popular sound effect module is obtained. Since the preset equalizer parameters include multiple sets of EQ, each set of EQ corresponds to a sound effect module, then the EQ corresponding to the popular sound effect module is obtained (represented by the frequency band adjustment parameter). For example, the EQ corresponding to the current sound effect module is Figure 7As shown, its EQ includes 31hz as -2db; 63hz as -1db, 125hz as 0db, 250hz as 1db, 500hz as 4db, 1khz as 3db, 2khz as 1db, 4khz as 0db, 8khz as -1db, and 16khz as 1db. Then the gain value of each frequency band is increased or adjusted according to the frequency band adjustment parameter. For example, the frequency band adjustment parameter corresponding to the sound effect module is to increase the frequency bands of 1khz and 2khz by 1db respectively. Of course, it is understandable that the frequency band adjustment parameters corresponding to other sound effect modules can also be to decrease the gain value, or to increase the gain value of one frequency band and decrease the gain value of the other frequency band, which is not limited here.

[0054] Figure 8 FIG. 1 is a flow chart of an equalizer adjustment method based on auricle scanning provided by another embodiment of the present invention. Figure 8 As shown, the equalizer adjustment method based on auricle scanning of this embodiment includes steps S210-S280. Steps S210-S240 are similar to steps S110-S140 in the above embodiment, and will not be repeated here. The following is a detailed description of steps S250-S280 added in this embodiment.

[0055] S250: Compare the auricle shape with the preset auricle shape that matches it to determine a difference value between the two.

[0056] S260: Adjust the current equalizer according to the difference value.

[0057] In one embodiment, because the preset auricle shape is a number of standard auricle shapes determined after countless auricle shape comparisons, and the auricle shape of each person is different, the auricle shape of the user is still different even compared with the preset auricle shape that matches best, and these differences will also lead to the defect of not being able to achieve the best hearing effect, so difference compensation is required. The difference value refers to the difference in appearance between the two auricle shapes. The difference value of this embodiment is characterized by a distance value, that is, the difference in distance between the auricles at various positions. For example, the coordinates of the user's auricle shape at point A are (X1, Y1, Z1), and the coordinates of the preset auricle shape matching the user's auricle shape at point A are (X2, Y2, Z2). The difference between the two coordinates is calculated as the distance value, which is used to characterize the difference value. The distance value is represented by a vector, and the distance value of each point is calculated and converted into a vector for representation, and then all the vectors are arithmetic averaged to finally obtain a difference value, for example, 10%, 20%. Finally, the current equalizer is adjusted according to the difference value, for example, the gain value of each frequency band is increased by 10%.

[0058] In one embodiment, if Fig. 9 As shown, the step S260 may include steps: S261-S262.

[0059] S261. When the difference value is a positive value, the value of each frequency band in the current equalizer is reduced.

[0060] S261. When the difference value is a negative value, increase the value of each frequency band in the current equalizer.

[0061] In other embodiments, the distance value between the coordinates of point A of the above two auricle shapes can also be represented by a dimensionless value, and the average distance value of each point on the X-axis, Y-axis and Z-axis is calculated, and one of the average distance values ​​is taken to represent the difference value. The maximum, minimum or middle distance value can be taken, and of course the average of the three can be used to represent the difference value. When the difference value is a positive number, the gain value of each frequency band is increased accordingly; when the difference value is a negative number, the gain value of each frequency band is decreased accordingly, thereby compensating for the difference in auricle shape, so that the adjustment of the equalizer is closer to the best hearing effect for the user.

[0062] S270: Play the test audio signal, wherein the test audio signal includes sounds of various frequency bands, and the sounds of various frequency bands are divided into several sections according to a time sequence for playback.

[0063] S280: Receive an adjustment signal provided by a user and adjust the equalizer according to the adjustment signal.

[0064] In one embodiment, after adjusting the rear equalizer, the present embodiment can also perform further audition adjustment, and the audition adjustment is mainly performed by playing a piece of audition music to the user, and the user further increases or decreases the gain value of each frequency band according to the comfort of the audition music. Specifically, the audition audio signal is also a piece of audition music. The audition audio signal includes the sound of all frequency bands, so that the user can hear the sound of each frequency band and make adjustments, and each frequency band is played according to the time sequence, for example, the 1Khz frequency band is played between the 5th and 10th seconds, and the 500hz frequency band is played between the 10th and 15th seconds. If the user feels that the sound effect is abnormally high between the frequency bands, the gain value of the frequency band can be lowered, and if the sound effect is abnormally low, the gain value of the frequency band can be increased. Among them, the adjustment signal is a control signal triggered by the user, which is used to increase or decrease the gain value of the frequency band. The adjustment signal can be triggered by a physical button or a touch screen slide, which is not limited here.
