Embodiment Construction

[0046] Combine below Figure 1 to Figure 13 , To further explain the present invention:

[0047] A surround-screen speaker array includes a plurality of speaker sub-arrays 2 distributed around a non-sound-permeable material screen. The non-sound-transmitting material screen is an LED screen 1 or an OLED screen or other non-sound-transmitting material screens with a display function.

[0048] Each speaker sub-array 2 is composed of multiple layers of transducers in different arrangements. Each loudspeaker sub-array 2 is composed of three layers of transducers with different arrangements and shapes, adopting a three-way sound signal processing method, and each layer corresponds to a different frequency band of the sound signal; among them, the first transducer group 21 in the lower layer The second transducer group 22 in the middle layer is responsible for processing the middle frequency band of the sound signal; the third transducer group 23 on the upper layer is responsible for pr...

Abstract

The present invention relates to a directional screen-surrounding speaker array and a control method thereof. The directional screen-surrounding speaker array comprises multiple sub-arrays of speakers (2) arranged around a screen made of a non-acoustically transmissive material. The present invention employs the solution in which multiple sub-arrays of speakers are arranged around a screen made of a non-acoustically transmissive material to solve the problem of infeasibility of a main sound channel sound reinforcement system in a non-acoustically transmissive cinema screen. The invention enables a non-acoustically transmissive screen to be used as a cinema screen, and employs a speaker array to realize adjustable directivities, thereby forming different directivities in different frequency bands.

Description

Technical field [0001] The invention relates to a ring-screen speaker array, in particular to a ring-screen speaker array suitable for domestic LED large screens and a control method thereof. Background technique [0002] In recent years, with the continuous improvement of domestic LED large-screen display technology, the resolution can reach the level of professional digital high-resolution projectors, and the screen size can no longer be restricted. The market urgently needs a digital cinema sound reproduction system that can match the LED large screen display video projection system. [0003] The material used for the curtain screen in the traditional movie theater is sound-transmitting material. The horn-type main sound reinforcement speaker system and the subwoofer are generally placed behind the sound-transmitting screen. But when the movie screen is made of non-sound-transmitting materials such as LED screens, the traditional sound reinforcement system of the main channel c...
