Description
Technical field
The present invention relates to speaker technology fields, and in particular to a kind of stage feedback loudspeaker enclosure.
Background technique
Before the lights, singer or the musician of band will listen accompaniment to sing, but the speaker on stage is towards spectators
Seat, so, the accompaniment sound that the accompaniment that singer hears really comes out from the speaker on stage travels to auditorium backmost
Wall then rebound accompaniment back, according to the spread speed of sound, sound returns in singer ear and spectators and hears
Accompaniment has delay in 1,2 second, this delay reflects length, reflected intensity and room-size etc. have according to reflection angle
Close relationship；So if singer listen return accompaniment sing again if, the effect that spectators hear is exactly that singer does not catch up with section
It plays.
It is to face singer, rather than face to see so can all have several king-sized speakers in the front of stage
Crowd, these speakers effect be exactly can allow accompaniment timely feedback to singer ear in, allow singer sing sound and accompaniment is melted
It is combined, is even fused together, can also there is certain delay, but people do not listen not come out generally, these are placed on
Feedback loudspeaker enclosure is known as on stage, in face of the speaker of singer.
The volume of existing feedback loudspeaker enclosure is big, more occupied space, and only have a woofer, not only volume compared with
It is small, bass effect is also had only, acoustics is less desirable, and additionally, due to the shape reason of the feedback loudspeaker enclosure, top surface does not have
Plate part, it has not been convenient to which singer interacts with the audience under platform.
Summary of the invention
In view of the above deficiencies, the object of the present invention is to provide a kind of smart structural designs, reasonable, small in size, volume
