Description

Technical Field

[0001] The present invention relates to the technical field of audio processing, and in particular to a method and device for ultra-high resolution time-sharing processing of audio signals based on household appliances. Background Art

[0002] With the use of high-performance computers to assist in the editing of a large number of music tracks with 128 independent audio tracks and the ability to move freely on a 360-degree 3D surround full virtual stage, with the sound source able to move up and down, consumers have to abandon the existing traditional HiFi playback devices with low imaging resolution, poor clarity, and insufficient sense of space, and instead seek a method and device for ultra-high resolution time-sharing processing of audio signals based on household appliances such as televisions, monitors, radios, speakers, sound bars, Bluetooth optical fiber speakers, smart glasses, Bluetooth headsets, wired headsets, etc., which can be used in AI scenarios on Internet platforms.

[0003] As technology continues to advance, household appliances such as televisions, radios, and headphones tend to be flatter, and the available acoustic space is becoming thinner and smaller. The audio space frequency response curve measured at the head of a person in a small activity space is a spatial frequency response curve with large fluctuations that is difficult to adjust due to standing wave interference caused by strong sound reflections from the four walls. This will seriously damage the image resolution, clarity, sense of space, and sound quality of the sound field in a small activity space.

[0004] For headphones with only one direct sound pressure field, users have to increase the loudness of the direct sound by more than 30 times, using the strong sound pressure of the direct sound pressure field to drive the cilia in the human cochlea to resonate and oscillate for nearly 30 milliseconds, replacing the missing 30 milliseconds of early reflected sound. However, this will simultaneously increase the hearing threshold of the human ear, reduce the dynamic range of the loudness of human hearing sounds, and make it impossible to clearly distinguish the details of audio below the human hearing threshold. More importantly, the super-strong sound pressure of the headphone's direct sound pressure field will cause permanent damage to the eardrum, cilia in the cochlea, and the auditory nerve, causing consumers' hearing to decline rapidly.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0025] By using the existing ordinary bass unit and the bare mid-high frequency loudspeaker, a 128-channel independent audio track ultra-high resolution sound field can be constructed for household appliances such as televisions, monitors, radios, stereos, echo walls, Bluetooth optical fiber speakers, smart glasses, Bluetooth headsets, wired headsets and other products. At the same time, in order to meet the market demand for high-quality car audio, the present invention is required to surpass the sound effects of mid-to-high-end floor-standing speakers or professional monitoring headphones and professional monitoring speakers in a small activity space with a net height of 1.4 to 2.4 meters and an area of ​​2 to 40 square meters. In order to expand the best listening area of ​​household appliances, break the limitation that there can only be one emperor listening seat, and realize that all seats in a small activity space are emperor listening seats (best listening area); each emperor listening seat is required to have a personal exclusive 128-channel independent audio track sound field and each sound field does not interfere with each other; the emperor listening seat is required to rotate 360 ​​degrees freely without affecting its stereo sound effect.

[0026] However, the audio spatial frequency response curve measured at the head of a person in a small activity space is a spatial frequency response curve with large fluctuations that is difficult to adjust due to the standing wave interference caused by the strong sound reflection of the four walls. This will seriously damage the image resolution, clarity, sense of space and sound quality of the ultra-high resolution sound field in a small activity space. For headphones with only one direct sound pressure field, headphone users have to increase the loudness of the direct sound by more than 30 times, and use the strong sound pressure of the direct sound pressure field to drive the cilia in the human cochlea to resonate and oscillate for nearly 30 milliseconds to replace the missing 30 milliseconds of early reflection sound. However, this will simultaneously increase the hearing threshold of the human ear, reduce the dynamic range of the human ear's hearing sound loudness, and thus make it impossible to clearly distinguish the details of music below the human ear's hearing threshold. More importantly, the super-strong sound pressure of the headphone's direct sound pressure field will cause permanent damage to the eardrum, cochlear cilia and ear nerves, causing consumers' hearing to decline rapidly.

[0027] The inventor has newly discovered that the sound field of 2-5KHz direct sound within 0-0.5 milliseconds that the human brain can quickly distinguish the directions of 128 independent sound tracks related to psychoacoustics is referred to as the Yuheng sound field; the sound wave sharpening function of the early reflected sound in the speaker with a delay of 0.5-1 millisecond is referred to as the Yuheng sound wave sharpening function; the suppression of the direction of the early reflected sound with a delay of 1-95 milliseconds is referred to as the Yuheng sound direction suppression. The human brain will classify the same sound field 0.34 meters away into the early reflected sound range of 1-95 milliseconds due to an extra delay of 1 millisecond, resulting in the Yuheng sound direction suppression. At the same time, it has the function of automatic sound expansion.

[0028] Combine the following Figure 1-Figure 4 The present invention describes an ultra-high resolution time-sharing processing method for audio signals based on household appliances, comprising: step 100, obtaining an original audio signal of the household appliance, and equally dividing the original audio signal into a first audio signal, a second audio signal and a third audio signal through a preset distributor.
