Abstract
The invention discloses a linear array loudspeaker high-pitch horn. A high-pitch horn body is formed by a left horn body and a right horn body by buckling; the left horn body and the right horn body are buckled to form into an internal chamber; a large-opening end of the internal chamber is a radiation opening; a small-opening end of the internal chamber is a sound source opening; a loudspeaker is installed at the sound source opening. The linear array loudspeaker high-pitch horn has the advantages of being reasonable in design, simple in structure and easy to machine, overcoming the disadvantages of a traditional high-pitch horn, greatly reducing interference between loudspeakers, greatly improving the upper limiting frequency of the loudspeakers due to the fact that upper limiting frequency of sound of a linear array loudspeaker is proportional to the interval between the loudspeakers and increasing the high pitch quality.
Description
Technical field
The present invention relates to stereo set technical field, specifically a kind of linear array sound equipment Horn.
Background technology
The effect of Horn is that the sound wave that high pitch loudspeaker produces is guided, and to assigned direction radiation, because linear array sound equipment can use many high pitch loudspeakers, the sound wave that different loud speaker produces produces interferes, and reduces the texture of high pitch.The sound wave that each tweeter vibrating diaphragm sends, almost arrives horn mouth plane at same time.Arrive, the sound wave that each several part vibrating diaphragm will be made to send is equal to the distance of nozzle plane simultaneously.Actual distance has longly to have short, and way is that short distance is elongated, finally makes various distance closely may be equal.A lot of audio supplies companies, in order to realize this purpose, have employed diverse ways.
summary of the invention
Technical assignment of the present invention is to provide a kind of linear array sound equipment Horn.
Technical assignment of the present invention realizes in the following manner, and Horn body is fastened by left bugle body and right bugle body and forms, and the big opening end of inner chamber is radiation port, and the osculum end of inner chamber is sound source mouth, and loud speaker is installed at sound source mouth place; In the inner chamber of left bugle body, be provided with many parallel gib blocks that are inclined upwardly, the inner chamber of left bugle body is separated into many sonic guide grooves by gib block, and the distance that sound wave is passed through from sound source mouth to radiation port is identical; In the inner chamber of right bugle body, be provided with many downward-sloping parallel gib blocks, the inner chamber of right bugle body is separated into many sonic guide grooves by gib block, and the distance that sound wave is passed through from sound source mouth to radiation port is identical; Sonic guide groove in sonic guide groove in left bugle chamber body and right bugle chamber body is crisscross arranged.By this design, make sound wave identical to the distance of radiation port from sound source mouth, form plane wave, spread out of equably from each radiation port, greatly reduce the interference between each loud speaker, loud speaker upper limiting frequency is improved greatly, improves the texture of high pitch.
Described left bugle body and the angle between the intrinsic sonic guide groove of right bugle and sound source mouth can flexible design.
Described Horn body is divided into odd numbers angle Horn body and even numbers angle Horn body, is provided with an inner chamber in the Horn body of odd numbers angle, is provided with two inner chambers in the Horn body of even numbers angle.
A kind of linear array sound equipment Horn of the present invention compared to the prior art, have reasonable in design, structure simple, be easy to the features such as processing, the not only customer service defect of common Horn, greatly reduce the interference between each loud speaker, and owing to being partitioned into direct ratio between the upper limiting frequency of linear CCD pushbroom sound and loud speaker, loud speaker upper limiting frequency is improved greatly.
