Problems solved by technology

[0003] However, the current high-power line-array full-range speakers, due to the application of indoor acoustic design, often have a large standing wave in the bass, which will cause the listener to hear inconsistent sound effects, greatly affecting the listener's listening experience

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] refer to Figure 1-2 , a non-equidistant full-frequency sound reinforcement processing method, comprising the following steps:

[0030] Step S1, obtaining the position of the main listening position;

[0031] Step S2, obtaining two groups of full-range speakers with different distances from the main listening position, the ones farther away from the main listening position are defined as the first group of full-range speakers, and the ones farther away from the main listening position are defined as the secon...

Abstract

The invention discloses a non-equidistant full-frequency sound amplification processing method and a non-equidistant full-frequency sound amplification processing system. The method comprises the following steps: obtaining the position of a main listening position; obtaining two groups of full-frequency sound boxes with unequal distances from the main listening position; the sound boxes far away from the main listening position are defined as a first group of full-frequency sound boxes, the sound boxes close to the main listening position are defined as a second group of full-frequency sound boxes; calculating the delay time according to the distance between the two groups of full-frequency sound boxes, adjusting the delay time of the second group of full-frequency sound boxes to obtain the frequency range of the second group of full-frequency sound boxes, and cutting off low and medium frequencies less than 1000 Hz from the second group of full-frequency sound boxes. Low and medium frequencies less than 1000 Hz are cut off from the second group of full-frequency sound boxes, and the characteristics of the first group of full-frequency sound boxes are not changed; therefore, the situation that low and medium frequencies are superposed with the low and medium frequencies of the first group of full-frequency sound boxes to generate low and medium frequency standing waves is avoided, and meanwhile, the delay time of the second group of full-frequency sound boxes is adjusted, so that the sounds of the two groups of full-frequency sound boxes can reach a listener at the same time, and a main listening position can obtain better listening feeling.

Description

technical field [0001] The invention relates to a sound reinforcement processing method, in particular to a non-equidistant full-frequency sound reinforcement processing method and system. Background technique [0002] High-power line-array full-range audio has the advantages of wide frequency range and wide coverage. It is easy to bring good sound field, imaging, instrument separation and layering, and the cost is relatively low, so more people will choose two sets High-power line array full-range speakers are installed at home to experience the beauty of sound. [0003] However, the current high-power line-array full-range speakers, due to the application of indoor acoustic design, often have a large standing wave in the bass, which will cause the listener to hear inconsistent sound effects and greatly affect the listener's listening experience. Contents of the invention [0004] In view of this, the present invention proposes a simple and effective non-equidistant full...
