Loud speaker and the medium-high frequency unit formed by the vertical array distribution of several middle/high frequency loudspeakers, the woofer are fixed on
The center of fixed plate, further includes the fixed seat that medium-high frequency unit is fixed on to babinet middle, and the fixed seat is fixed
In in fixed plate, woofer is located at the positive rear end setting of medium-high frequency unit, further include be able to push woofer,
The channel power amplifier and digital audio processor of medium-high frequency unit, being additionally provided with being capable of remote control and debugging speaker
RS485 protocol signal interfaces, the RS485 protocol signals interface being capable of control channel power amplifier and digital audio processing
Device makes array speaker send out cylindrical wave.
The utility model is further arranged to, the babinet upper surface be equipped with can elastic shrinkage protrusion, the babinet
Lower surface is equipped with and the matched groove of protrusion with raised corresponding section.
The utility model is further arranged to, the bottom of the babinet be equipped with can elastic shrinkage protrusion, the top of babinet
It is equipped with and the matched groove of protrusion with raised corresponding section.
The utility model has the advantages that：
1. the utility model array speaker, expands the horizontal directivity of speaker, limits vertical directivity, produce
With the farther range of vertical directivity, meets the needs in high reverberation place and outdoor Far Range public address, saved production cost
With 2 convenience in transport
2. array speaker can orthogonal array, the distance between two neighboring low loud speaker acoustic centres are arranged in battle array
The sound source set for arranging and having between sound source regular spacing, being equivalent to its size and entirely gathering identical single sound source expires
The correct coupling of foot
3. array built in sound box digital processing unit correctly applies wave surface to correct technology, what line source system generated
Cylindrical wavefront can realize the cylindrical wave work of the horizontal permutation of more speakers and orthogonal array with 4 kinds of switch modes
4. array speaker, the sound wave sent out is cylindrical wave, can effectively control the directive property of speaker, prevent unnecessary
Diffusion and reflection, effectively improve the clarity of sound, and cylindrical wave has farther range, from front to back, form covering evenly
Lid provides with preferable sound quality, preferable covering, shirtsleeve operation, remote control, more effectively utilizes booster output
System, the effective solution direction sex chromosome mosaicism of sound vertical direction can be efficiently reduced for the bad place of architectural acoustics
The reflected sound of vertical direction promotes speech articulation and intelligibility.Traditional speaker system projection is spherical wavefront,
Uniform expansion in horizontal and vertical two planes.Sound pressure level（SPL）Obey inverse square law, when distance doubles, acoustic pressure
Grade declines 6dB.Cylindrical wavefront, when distance doubles, sound pressure level declines 3dB, from front to back, forms covering evenly
Lid.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
In conjunction with shown in Fig. 1 to Fig. 6, a kind of array speaker, including front end are in the babinet 1 of opening setting, are set to babinet 1
Interior combination loudspeaker and the fixed plate 2 positioned at opening, the combination loudspeaker include woofer 3 and by several
The medium-high frequency unit that 4 vertical array distribution of a middle/high frequency loudspeaker is formed, the woofer 3 are fixed in fixed plate 2
Heart position, further includes the fixed seat 5 that medium-high frequency unit is fixed on to babinet middle, and the fixed seat 5 is fixed on fixed plate 2
On, woofer 3 is located at the positive rear end setting of medium-high frequency unit, further includes being able to push woofer, medium-high frequency
The channel power amplifier and digital audio processor of unit are additionally provided with the RS485 agreements for capableing of remote control and debugging speaker
Signaling interface, the RS485 protocol signals interface can control channel power amplifier and digital audio processor make array
Formula speaker sends out cylindrical wave.
In above structure, the RS485 protocol signals interface can be at control channel power amplifier and digital audio
Reason device makes array speaker send out cylindrical wave, fixed plate 2 and middle/high frequency loudspeaker 4 to be separately fixed at babinet 1 and solid by bolt
On fixed board 2, array speaker is coaxial structure by woofer 3 and 4 array of middle/high frequency loudspeaker, and physical positioning is close
In point sound source, the sound field positioning for resetting music is highly desirable；The middle seated position of woofer 3, it can be achieved that more speakers it is vertical
Or horizontal array installation, it is compared with single loud speaker, loudspeaker array can promote acoustical power, acoustic radiation effect when increasing low frequency
Rate improves directive property to improve sound field nonunifornity and improve the speech intelligibility in reverberant ambiance.
In the present embodiment, the middle/high frequency loudspeaker 4 is set as six, and the opening of the babinet 1 is provided with guard
6。
