Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. The illustrations only show the components related to the present invention, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0024] Refer to Figure 1 . The following embodiments of the present invention provide an audio effect adjustment system. Compared with the prior art, the present invention provides a three-dimensional audio effect adjustment system. By using the user's gestures and combining with a ranging module, it can realize the adjustment function of the audio effect according to the user's gestures and the distance between the user's touching hand and the touch control module, making the audio effect adjustment more intelligent.

[0025] Next, the technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0026] As Figure 1 shown, in one embodiment, the present invention provides an audio effect adjustment system, and the audio effect adjustment system includes: a touch control module 1, an image acquisition module 2, an image processing module 3, a ranging module 4, a general processing module 5, and a sound source playback device 6.

[0027] Specifically, the touch control module 1, the ranging module 4, the image processing module 3, and the sound source playback device 6 are all connected to the general processing module 5; the image processing module 3 is further connected to the image acquisition module 2; the ranging module 4 is disposed on the touch control module 1 (the purpose is to make the distance measured by the ranging module 4 between the touching hand and the ranging module 4 equal to the distance between the touching hand and the touch control module 1).

[0028] It should be noted that when the user adjusts the target sound effect, the user's touching hand touches the touch control module 1, causing the touch control module 1 to send a touch control signal to the general processing module 5; the image acquisition module 2 acquires a real-time image and sends the real-time image to the image processing module 3; the real-time image includes an image of the touching hand; the image processing module 3 obtains a real-time gesture signal corresponding to the touching hand based on the real-time image and sends the real-time gesture signal to the general processing module 5; the general processing module 5 determines whether a target gesture signal is received based on the real-time gesture signal, and when it is determined that the target gesture signal is received, controls the ranging module 4 to start working; when the ranging module 4 starts working, the ranging module 4 acquires a distance signal between the touching hand and the touch control module 1 and sends the distance signal to the general processing module 5; the general processing module 5 determines the target sound effect based on the touch control signal, obtains a sound effect adjustment signal corresponding to the target sound effect based on the distance signal, and sends the sound effect adjustment signal to the sound source playback device 6, so that the sound source playback device 6 adjusts the target sound effect of the original sound source based on the sound effect adjustment signal to achieve the playback of the target sound source.

[0029] It should be noted that when the general processing module 5 receives the target gesture signal, it indicates that the sound effect adjustment gesture action is completed. At this time, the general processing module 5 controls the ranging module 4 to start measuring the distance between the touching hand and the touch control module 1, and this distance is used for subsequent sound effect adjustment.

[0030] It should be noted that the target gesture signal corresponds to the target gesture of the user's touching hand. What specific form this target gesture is does not limit the present invention. In actual applications, it can be set according to specific application scenarios; for example, the gesture of clenching a fist can be set as the target gesture.

[0031] In one embodiment, the distance signal includes at least but is not limited to the distance between the touching hand and the touch control module 1 measured by the ranging module 4.

[0032] In one embodiment, when the general processing module 5 receives the touch control signal, the general processing module 5 controls the image acquisition module 2 to start acquiring real-time images.

[0033] In one embodiment, the general processing module 5 is connected to the touch control module 1, the ranging module 4, the image processing module 3, and the sound source playback device 6 through an SPI bus.

[0034] In one embodiment, the image acquisition module 2 is connected to the image processing module 3 through a PCIe bus.

[0035] In one embodiment, the image acquisition module 2 employs a binocular camera module.

[0036] In one embodiment, the image processing module 3 uses a graphics processing unit.

[0037] It should be noted that the full English name of the graphics processing unit is Graphics Processing Unit, and its English abbreviation is GPU. It is also known as the display core, display chip, and video processor. It is a coprocessor used for processing image and graphics operations. It is a chip designed specifically for performing complex mathematical calculations and graphics rendering. The GPU can handle a large number of parallel computing tasks, thereby accelerating the execution speed of graphics rendering and complex mathematical calculations.

[0038] It should be noted that in the present invention, the image processing module 3 uses conventional technical means in the field to obtain real-time gesture signals based on real-time images. The specific working principle is as follows:

[0039] Whether the gesture is static or dynamic, the recognition sequence first requires image acquisition, hand detection and segmentation, and gesture analysis, and then static or dynamic gesture recognition. Gesture segmentation is a crucial step in the gesture recognition process, and the effect of gesture segmentation directly affects the next gesture analysis and the final gesture recognition. Currently, the most commonly used gesture segmentation methods mainly include gesture segmentation based on monocular vision and gesture segmentation based on stereo vision.

[0040] Among them, monocular vision uses an image acquisition device to obtain a gesture and obtain a planar model of the gesture. The method of establishing a gesture shape database is to establish all gestures that can be considered, which is conducive to gesture template matching, but the computational complexity increases accordingly, which is not conducive to the rapid recognition of the system.

[0041] The binocular camera module belongs to stereo vision, which uses multiple image acquisition devices to obtain different images of the gesture and converts them into a stereo model. The method of stereo matching is similar to the template matching method in monocular vision, and a large number of gesture libraries also need to be established; while three-dimensional reconstruction requires establishing a three-dimensional model of the gesture, and the computational complexity will increase, but the segmentation effect is better.

[0042] Gesture analysis is one of the key technologies for completing a gesture recognition system. Through gesture analysis, the shape features or motion trajectories of the gesture can be obtained. The shape and motion trajectories of the gesture are important features in dynamic gesture recognition and have a direct relationship with the meaning expressed by the gesture. The main methods of gesture analysis are as follows: edge contour extraction method, multi-feature combination method such as centroid and finger, and knuckle tracking method, etc.

[0043] The edge contour extraction method is one of the commonly used methods for gesture analysis. The hand shape is distinguished from other objects due to its unique appearance. A gesture recognition algorithm that combines geometric moments and edge detection is adopted. By setting the weights of two features, the distance between images is calculated to achieve the recognition of alphabet gestures. The multi-feature combination method analyzes the gesture posture or trajectory based on the physical characteristics of the hand; gesture recognition is achieved by combining the gesture shape and finger tip features. The knuckle tracking method mainly constructs a two-dimensional or three-dimensional model of the hand and then tracks based on the position changes of the hand joint points, which is mainly applied to dynamic trajectory tracking.

[0044] Gesture recognition is the process of classifying the trajectory (or point) in the model parameter space into a certain subset in this space, which includes static gesture recognition and dynamic gesture recognition. Dynamic gesture recognition can ultimately be transformed into static gesture recognition. From the perspective of the technical implementation of gesture recognition, common gesture recognition methods mainly include: template matching method, neural network method, and hidden Markov model method. The template matching method regards the gesture action as a sequence composed of static gesture images, and then compares the gesture template sequence to be recognized with the known gesture template sequence to recognize the gesture.

[0045] In one embodiment, the ranging module 4 uses a laser rangefinder.

[0046] It should be noted that a laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. The measurement range of the laser rangefinder is 3.5 to 5000 meters.

[0047] The principle of laser ranging is mainly based on the characteristic that the propagation speed of light remains constant. The distance between the target object and the measuring instrument is calculated by measuring the time required for the laser beam to travel from emission to reception. The laser rangefinder emits a laser beam, which irradiates the target object (i.e., the touch hand of the present invention) and is reflected back. The receiver of the rangefinder records the time interval from the emission to the reception of the laser. The distance between the target object and the laser rangefinder is calculated through the formula "distance = light speed × time".

[0048] As Figure 1 shown, in one embodiment, the sound source playback device 6 includes: a sound source input module 601, an audio processing module 602, a power amplification module 603, and a speaker module 604.

[0049] Specifically, the audio processing module 602 is respectively connected to the sound source input module 601, the power amplification module 603 and the general processing module 5; the power amplification module 603 is further connected to the speaker module 604; the sound source input module 601 inputs the original sound source to the audio processing module 602; the audio processing module 6062 adjusts the target sound effect of the original sound source based on the sound effect adjustment signal, and transmits the adjusted original sound source to the power amplification module 603; after the power amplification module 603 amplifies the power of the adjusted original sound source, the target sound source is obtained, and the speaker module 604 plays the target sound source.

[0050] It should be noted that the sound source input module 601 is responsible for inputting the corresponding audio program (i.e., the original sound source) and transmitting the audio signal to the audio processing module 602. The sound source input module 601 adopts conventional technical means in the field, so it will not be elaborated in detail here.

[0051] The power amplification module 603 adopts conventional technical means in the field. It generally refers to a most basic device in an audio system. Its task is to amplify the weak electrical signal from the signal source to drive the speaker to emit a sound with sufficient loudness.

[0052] The speaker module 604 is responsible for converting the analog audio electrical signal into mechanical energy and transmitting it to the human ear through the air. It adopts conventional technical means in the field, so it will not be elaborated in detail here.

[0053] In one embodiment, the audio processing module 602 uses a digital signal processor.

[0054] It should be noted that the full name of the digital signal processor is Digital Signal Processor, and the abbreviation is DSP; digital signal processing is a process of converting real signals in the real world (professional term called continuous signals) into information that can be processed by a computer. For example, the sound of people speaking is a continuous signal. In addition, there are many such signals in real life, such as light, pressure, temperature, etc. These signals go through an analog-to-digital conversion process (called AD), become digital signals and are sent to the processor for digital calculation. After the processing is completed, the result is converted back into a continuous signal through a digital-to-analog conversion process (called DA).

[0055] In one embodiment, the general processing module 5 includes: a central processing unit.

[0056] Specifically, the central processing unit is respectively connected to the touch control module 1, the distance measurement module 4, the image processing module 3 and the sound source playback device 6.

[0057] It should be noted that the central processing unit, with the full English name: Central Processing Unit and the English abbreviation CPU, is one of the main devices of an electronic computer and a core component in a computer. Its main function is to interpret computer instructions and process data in computer software. The CPU is the core component in a computer responsible for reading instructions, decoding instructions, and executing instructions. The central processing unit mainly includes two parts, namely, a controller and an arithmetic unit, and also includes a cache memory and buses for data and control to realize the connection between them.

[0058] In one embodiment, the total processing module 5 obtaining the sound effect adjustment signal corresponding to the target sound effect based on the distance signal includes: the total processing module 5 obtaining the sound effect adjustment signal based on the corresponding relationship and the distance signal; wherein, the corresponding relationship is the relationship between different effects of the target sound effect and corresponding different target distances; the target distance is the distance between the touch hand and the touch control module 1.

[0059] In one embodiment, the distance between the touch hand and the touch control module 1 is divided into n levels, where n≥2 and n is an integer; each level corresponds to an effect of the target sound effect;

[0060] Xmax / n>a;

[0061] Xmax represents the maximum distance between the touch hand and the touch control module 1; a represents the ranging error of the ranging module 4, which is a fixed value (depending on the ranging module 4 itself); the distance signal corresponds to the target distance; the sound effect adjustment signal corresponds to the effect.

[0062] It should be noted that the specific value of n is not a condition for limiting the present invention, and in practical applications, it can be set according to specific application scenarios; generally speaking, the more the number of levels n, the more coherent the change and the finer the granularity.

[0063] It should be noted that Xmax actually corresponds to the effective distance for gesture adjustment of the sound effect, that is, when the distance between the touch hand and the touch control module 1 is greater than this Xmax, it is considered that any action of the touch hand is meaningless, and only when the distance between the touch hand and the touch control module 1 is less than or equal to this Xmax, the gesture of the touch hand is considered effective; the specific value set for it is not a condition for limiting the present invention, and in practical applications, it can be set according to specific application scenarios.

[0064] Specifically, according to the distance between the touch hand and the touch control module 1 measured by the ranging module 4, the adjustment effect on the target sound effect is determined, that is, the sound effect adjustment signal is determined.

[0065] In one embodiment, the sound source playback device 6 adjusts the target sound effect of the original sound source based on the sound effect adjustment signal, including: the sound source playback device 6 adjusts the time domain and / or frequency domain of the original sound source based on the sound effect adjustment signal to achieve the adjustment of the target sound effect of the original sound source.

[0066] In one embodiment, the target sound effect includes at least but is not limited to any one of the following: sound field, reverberation, surround sound.

[0067] It should be noted that when the target sound effect is the sound field, the different effects of the corresponding target sound effect are reflected in the distance of the sound field. Specifically, different target distances correspond to different distances of the sound field; when the target sound effect is reverberation, the different effects of the corresponding target sound effect are reflected in the depth of the reverberation. Specifically, different target distances correspond to different depths of the reverberation; when the target sound effect is surround sound, the different effects of the corresponding target sound effect are reflected in the size of the surround feeling of the surround sound. Specifically, different target distances correspond to different sizes of the surround feeling of the surround sound.

[0068] It should be noted that the above touch control module 1 uses conventional technical means in the field, and it can generate corresponding touch control signals when the user's touch hand touches the touch control module 1; for example, the touch control module 1 is a touch screen, so the working principle thereof will not be described in detail herein.

[0069] The present invention realizes the control of sound effect adjustment in a three-dimensional (gesture) control manner, with convenient and efficient operation.

[0070] The working principle of the audio adjustment system of the present invention will be further explained and illustrated below through specific embodiments.

[0071] In one embodiment, the audio adjustment system is applied to adjust the distance of the sound field, that is, the target sound effect is the sound field.

[0072] Specifically, when the touch screen module (corresponding to the above touch control module 1) detects the touch control area of the human hand (corresponding to the above touch hand), it emits relevant touch control signals and transmits them to the CPU module (corresponding to the above general processing module 5) through the SPI bus. The CPU module determines the sound effect adjustment function (i.e., the target sound effect) to be operated by the user according to this touch control signal.

[0073] Meanwhile, the binocular camera module (corresponding to the above-mentioned image acquisition module 2) captures the hand image (corresponding to the above-mentioned real-time image), and the graphics processor (corresponding to the above-mentioned image processing module 3) recognizes the gesture changes of the hand based on the hand image. The precise change distance (i.e., the distance between the touch hand and the touch control module 1 mentioned above) is measured by the laser ranging module (corresponding to the above-mentioned ranging module 4), and the gesture signal (corresponding to the above-mentioned real-time gesture signal) and the distance change signal (corresponding to the above-mentioned distance signal) are transmitted to the CPU module through the SPI bus.

[0074] When the CPU module receives the touch control signal, it determines the sound effect adjustment function to be adjusted. According to the real-time gesture signal transmitted by the graphics processor and the distance change signal sent by the laser ranging module, it calculates the level of the sound effect function to be adjusted and sends the relevant control signal to the DSP module (corresponding to the above-mentioned audio processing module 602).

[0075] The DSP module processes the time-domain and frequency-domain characteristics of the audio signal according to the control signal sent by the CPU module to achieve the function of sound effect adjustment. The adjusted audio signal is transmitted to the power amplifier module (corresponding to the above-mentioned power amplification module 603), and the amplified audio signal drives the speaker (corresponding to the above-mentioned speaker module 604) to emit sound.

[0076] Set the upper and lower limits of the adjustment range of the sound effect adjustment frequency domain and time-domain signals (this upper limit cannot be increased without limit, mainly for hearing protection and listenability, and then allocate according to the distance level. In terms of the frequency domain, the higher the high frequency, the closer the sound image position, and vice versa. In terms of the time-domain signal, the shorter the delay, the closer the sound image position, and the longer the delay, the longer the sound image position.

[0077] When the hand moves away from the screen, the frequency-domain signal decreases from low frequency to high frequency. For the time-domain signal, the delay time increases, achieving the effect of the sound image moving away.

[0078] Set the upper and lower limits of the adjustment range of the sound effect adjustment frequency domain and time-domain signals, and then allocate according to the distance level. In terms of the frequency domain, the higher the high frequency, the closer the sound image position, and vice versa. In terms of the time-domain signal, the shorter the delay, the closer the sound image position, and the longer the delay, the longer the sound image position.

[0079] It should be noted that the propagation distance of sound in the conventional ambient air is about 34 cm / ms, and the approximate calculation formula is: sound image position cm ≈ the delay time t1 of all front-row speakers × 34 cm.

[0080] The descriptions of the processes or structures corresponding to the above various drawings have their own focuses. For the parts not detailed in a certain process or structure, reference can be made to the relevant descriptions of other processes or structures.

[0081] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
