Stage feedback loudspeaker box

Abstract

The invention discloses a stage feedback loudspeaker box. The stage feedback loudspeaker box comprises a box body, wherein the contour of the cross section of the box body is shaped like a right trapezoid; two mid-range loudspeakers and two coaxial loudspeakers are arranged on an inclined panel of the box body; a sound amplifying module is arranged on a vertical back plate; the inclination angle of the inclined panel is between 40 degrees and 50 degrees; the width of a top flat plate is between 3cm and 30cm. The stage feedback loudspeaker box provided by the invention has the advantages that the box body adopts an irregular structural design, so that standing waves in the box body can be reduced, and the tone is cleaner; with the top flat plate, a singer can conveniently sit or place his / her feet on the box body, so that the interactivity with the audience is effectively enhanced; the inclined panel is arranged at an angle of 40 degrees to 50 degrees, so as to effectively ensure that the sound axis can be directly oriented to the ears of the singer, and achieve good radiation effects; the two coaxial loudspeakers and the two mid-range loudspeakers not only achieve a large volume, good layering effects and high appealingness, but also achieve an ampler frequency allocation of the loudspeaker box, smooth cohesion among high-frequency tones, middle-frequency tones and low-frequency tones, and a wide sound field, so that the overall tone quality is improved.

Description

technical field

[0001] The invention relates to the technical field of sound boxes, in particular to a stage feedback sound box. Background technique

[0002] On the stage, the singer or the musicians of the band need to listen to the accompaniment to sing, but the speakers on the stage face the auditorium, so the accompaniment heard by the singer is actually the accompaniment sound from the speakers on the stage, which spreads to the auditorium The accompaniment that bounces back from the back wall, according to the propagation speed of the sound, there is a delay of 1 or 2 seconds between the sound returning to the singer’s ear and the accompaniment heard by the audience. This delay depends on the reflection angle, reflection length, reflection intensity, and The size of the room and so on are closely related; therefore, if the singer listens to the returned accompaniment and then sings, the effect heard by the audience is that the singer cannot keep up with the rhythm. ...
