Description
Technical field
The present invention relates to public address system technical field, particularly a kind of linear array full range sound column.
Background technology
It is arranged into an array that sound column is generally more than 2 loudspeakers, produces plane sound field, in the range of certain listening, sound
Attenuation ratio point sound source it is much lower.Such as 5 meters of listening distance, point sound source has about been decayed 14dB, and the sound being designed to
Its decay of post only has 7 dB, it then follows be one times of gap, it is therefore more obvious apart from more remote gap.Certainly, this is also intended to
It is only what is reached in the effective range of the flat field of sound column.The case chamber of sound column is also required to set pilot hole ability under normal circumstances
Discharge low-frequency sound wave, being generally directed toward hole can be arranged on by loudspeaker, but set anyway, between pilot hole and pilot hole between
Away from that still can make it that part low-frequency sound wave is hindered, cause to produce loss, and processing is also improved for the manufacture of sound column case chamber
Difficulty.
The content of the invention
The technical problem to be solved in the present invention is：A kind of linear array full range sound column is provided, its case cavity configuration solves tradition
Sound column set pilot hole occur low-frequency sound wave loss technical problem.
The present invention solve its technical problem solution be：
Linear array full range sound column, including housing and installed in several positive loudspeakers of housing, the housing includes bottom wall, top
Wall and post jamb, the post jamb are elongated, including outer wall, antetheca and guide wall, and the outer wall is by left wall, right wall and back wall group
Into, the left wall and right wall are fixedly connected with back wall, and one end of the antetheca is fixedly connected with left wall or right wall, the other end with
Guide wall is fixedly connected, and the guide wall is located in the cavity that outer wall and antetheca are surrounded and guide channel is formed between outer wall.
Further, the post jamb is integrally formed section bar.
Further, the antetheca is provided with loudspeaker mounting hole, and the loudspeaker mounting hole is adapted with loudspeaker.
Further, the arrival end of the guide channel is towards the back side of loudspeaker, and the front of the port of export and loudspeaker is side by side.
Further, the section of the back wall is curved, and the guide wall includes being oriented to side wall and is oriented to rear wall, the guiding
The two ends of side wall are fixedly connected with antetheca and guiding rear wall respectively, and the section for being oriented to rear wall is curved and is mutually fitted with back wall
Match somebody with somebody.
Further, the width of the guide channel is gradually narrowed by arrival end to the port of export.
The beneficial effects of the invention are as follows：The present invention has abandoned traditional guiding pore structure, and it is linear pattern battle array to be changed to the port of export
The guide channel structure of row so that the full range sound wave in sound column（Mainly low-frequency sound wave）Can uniformly and comprehensively from sound column just
Face spread out is gone.Simultaneously as guide channel is linear array so that its without as traditional direction hole to sound column before
Wall carries out multiple perforate processing, greatlys save processing charges, improves product qualification rate.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, makes required in being described below to embodiment
Accompanying drawing is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present invention, rather than is all implemented
Example, those skilled in the art on the premise of not paying creative work, can also obtain other designs according to these accompanying drawings
Scheme and accompanying drawing.
Fig. 1 is the partial schematic diagram in the linear array full range sound column main view direction；
Fig. 2 is the view in full section of the linear array full range sound column overlook direction.
Embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing clear
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to constitute more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
With reference to Fig. 1 and 2, linear array full range sound column, including housing and installed in several positive loudspeakers 5 of housing, institute
Stating housing includes bottom wall, roof and post jamb, and the post jamb is elongated, including outer wall 1, antetheca 2 and guide wall 3, the outer wall 1
It is made up of left wall 11, right wall 12 and back wall 13, the left wall 11 and right wall 12 are fixedly connected with back wall 13, the antetheca 2
One end is fixedly connected with left wall 11 or right wall 12, and the other end is fixedly connected with guide wall 3, and the guide wall 3 is located at outer wall 1 with before
Guide channel 4 is formed in the cavity that wall 2 is surrounded and between outer wall 1.Because guide channel 4 is axially arranged on whole post jamb
On, and its arrival end connects with the cavity in housing, and the port of export is then located at the front of housing so that mainly in loudspeaker 5
The low-frequency sound wave that the back side is produced can be delivered to the front of linear array full range sound column along guide channel 4.The guiding of linear array
Passage 4 can also reduce the difficulty of processing of housing, it is to avoid antetheca 2 is repeatedly punched as traditional pilot hole.
It is further used as preferred embodiment, the post jamb is integrally formed section bar.The post jamb is extruding or drawing
The section bar of type is stretched into, the operating efficiency for making housing can be greatly promoted.
Be further used as preferred embodiment, the antetheca 2 be provided with loudspeaker mounting hole, the loudspeaker mounting hole with
Loudspeaker 5 is adapted.
It is further used as preferred embodiment, the arrival end of the guide channel 4 is exported towards the back side of loudspeaker 5
End and the front of loudspeaker 5 are side by side.
It is further used as preferred embodiment, the section of the back wall 13 is curved, the guide wall 3 includes being oriented to side
Wall 31 and guiding rear wall 32, the two ends of guiding side wall 31 are fixedly connected with antetheca 2 and guiding rear wall 32 respectively, described to be oriented to
The section of rear wall 32 is curved and is adapted with back wall 13.Under the back wall 13 and the guiding collective effect of rear wall 32 of arc so that
Guide channel 4 forms the passage of one section of arc at arrival end, effectively changes the hair for the low-frequency sound wave that the back side of loudspeaker 5 is produced
Outgoing direction.
It is further used as preferred embodiment, the width of the guide channel 4 is gradually narrowed by arrival end to the port of export.
The better embodiment to the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent modifications or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
