A stage sound system, stage structure and stage sound system layout method

Abstract

The invention relates to a stage audio system, a stage structure and a stage audio system arrangement method. The stage audio system comprises a plurality of micro linear-array speaker boxes, wherein the linear-array speaker boxes comprise long-strip high-medium frequency speaker boxes and square low-frequency speaker boxes. The long-strip high-medium frequency speaker boxes stretch to a ceiling of a stage from the ground of the stage, and are overlapped vertically to form a long-strip structure. The long-strip structure is embedded into a clearance between two colored curtains on the side wall of the stage, and the long-strip structure on the left side and the long-strip structure on the right side of the side wall of the stage are symmetrical. The low-frequency speaker boxes are symmetrically arranged behind the colored curtains on the side wall of the stage. Horizontal covering angle of output sound is wide, and vertical covering angle of the sound is narrow.

Description

technical field [0001] The invention relates to a sound system, in particular to a stage sound system, a stage structure provided with the stage sound system, and a stage sound system layout method. Background technique [0002] In order to enhance the overall sense and gorgeous effect of the stage and satisfy the audience's visual aesthetic enjoyment, a large number of LED screens are usually used on the background wall, ceiling and floor of the stage of the studio, and some stages even extend directly to the last row of the auditorium. Form a T-shaped stage, so that the studio becomes a complete stage performance space from the ground to the ceiling. Performing on such a stage with almost 360° LED screens, it is very critical to ensure that each actor can clearly hear the return sound at any point in such a space. [0003] The traditional stage sound return system usually uses full-band point sound source return speakers, and the speakers are placed on the stage or hung o...

AI Technical Summary

Problems solved by technology

Because the sound horizontal and vertical coverage angles of point sound source speakers are usually relatively large, it will cause a large number of sound reflections relative to the ground and side LED screens, affecting sound clarity, and will also cause uneven sound in the stage area, that is, the distance from the speaker is close to the sound The pressure level is large, but the sound pressure level far away from the speaker is small

[0006] This not only causes the actors to be unable to hear the return sound clearly, but also affects the audience's audio-visual experience.

[0007] Secondly, because the acoustic sound-absorbing cavity of the existing stage, which was originally located behind the audience area, was blocked by the LED screen, the expected sound-absorbing effect could not be achieved. On the premise that the actors themselves could not clearly hear the return sound, the opposite echo appeared. interference, which ultimately leads to the worsening of the entire sound field environment

[0008] In addition, since the stage is almost covered by 360° LED screens, that is to say, the ground, surroundings and ceiling of the entire stage are all luminous bodies. It looks unusually abrupt on the stage, and it will destroy the complete visual effect of the stage
