Abstract
The utility model discloses level all referring to the phased speaker system of subregion, including：The upper and lower ends of loudspeaker mounting plate are connected with upper cover plate and lower cover, loudspeaker mounting plate in the horizontal direction array into a regular polygon, protection entrant sound net and loudspeaker mounting plate array into the regular polygon of be in vertical direction same center.All loudspeakers are installed on loudspeaker mounting plate, so that a closed back cavity is constituted, such as same air-cushion type audio amplifier.When loudspeaker simultaneously sounding, and all directions acoustic pressure it is equal when, in the horizontal direction equivalent to a sound source for omnidirectional's sounding, be monolithically fabricated a full directional loudspeaker of level.The level is that an independent input line is connected to phased zonal device or is divided into some groups of input lines and is connected to phased partition hander all referring to each loudspeaker to subregion phase inside loudspeakers.Because phased partition hander can individually adjust the function of control with the power output to each loudspeaker or every group of loudspeaker, effective frequency range, electrical signal phase, harmonic distortion, it is achieved that the utility model level is all referring to the invention to the phased speaker system of subregion.
Description
Technical field
The utility model is related to a kind of speaker system, is related specifically to one kind all referring to the phased loudspeaker system of subregion
System.Acoustic energy can be reduced to waste and sound pollution, energy-conserving and environment-protective are realized, the purpose not disturbed residents.
Background technology
Traditional broadcast propaganda car, installs loudspeaker to realize omni broadcast typically on the not direction of car.Installation wiring
Complexity, and the outward appearance of car is not succinct enough, windage is big during traveling, and loudspeaker is easily blown bad.
The usual surrounding of conventional omni-directional loudspeaker van is sounding simultaneously, and acoustic pressure is equal.In overlay area dissymmetrical field
During institute's public address, some direction public address are nearer apart from crowd, some direction public address apart from crowd farther out, but due to the sound in all directions
Pressure is identical.If in order to be adapted to public address on long distance direction, output acoustic pressure is larger, then crowd's sense of hearing is rung very much, felt bad on low coverage direction；
If in order to be adapted to public address on low coverage direction, output acoustic pressure is smaller, then crowd does not hear, can't hear on long distance direction.
The content of the invention
In view of above-mentioned problem, the utility model multiple effective frequencies rule enclose that wide, frequency response is basically identical, body
The less loudspeaker of product in the horizontal direction array into a regular polygon, and in the horizontal direction close to a point sound source.From
And the sound pressure uniform around causing, because small volume, windage is smaller, is more beneficial for place that is vehicle-mounted or needing omnidirectional's public address
Install.Again because circuit Relatively centralized, installation wiring is more convenient.
Utility model carries out public address with the phased management of subregion, the direction to broadcast in need is capable of achieving, it is not necessary to broadcast
Direction not sounding.Or output sound pressure level can be reduced on the direction of closely public address；Above carried in the direction of remote public address
Height output sound pressure level.Wasted and sound pollution so as to reduce acoustic energy, improve sense of hearing comfort level, realize the purpose of energy-conserving and environment-protective；
The present invention using close human body subtract should and DSP phase control techniques, be capable of achieving broadcast is tracked to crowd.
Brief description of the drawings
Fig. 1 is that the utility model level regards configuration diagram all referring to the phased loudspeaker mansion of subregion；
Fig. 2 is the utility model level all referring to the phased loudspeaker vertical section configuration diagram of subregion；
Fig. 3 is the utility model level all referring to the phased speaker system functional-block diagram of subregion.
Specific embodiment
Referring to accompanying drawing 1, Fig. 2, level is all referring to the phased loudspeaker of subregion, including a protection entrant sound net is 1., protects entrant sound net
1. 5. 4. upper and lower ends be connected with upper cover plate with lower cover, constitutes a guard shield for horizontal direction omnidirectional entrant sound, from
It is in regular polygon or circle that top mansion regards shell.
5. 4. loudspeaker mounting plate upper and lower ends 2. be connected with upper cover plate with lower cover, and loudspeaker is installed and fixed
Plate 2. in the horizontal direction array into a regular polygon, and the protection entrant sound net 1. with loudspeaker mounting plate 2. array
It is in vertical direction same center into the regular polygon of.
3. all loudspeakers are installed in loudspeaker mounting plate and 2. go up, so that a closed back cavity is constituted, as
One air-cushion type audio amplifier.It is complete equivalent to one in the horizontal direction when loudspeaker 3. sounding simultaneously, and all directions acoustic pressure are equal
To the sound source of sounding, a full directional loudspeaker 15 of level is monolithically fabricated.
Referring to accompanying drawing 3,3. each loudspeaker inside the full directional loudspeaker 15 of level is that an independent input line is connected to
Phased partition hander 14 is divided into some groups of input lines and is connected to phased partition hander 14.Because phased partition hander 14
With to each loudspeaker 3. or every group of loudspeaker power output 3., effective frequency range, electrical signal phase, harmonic distortion can be independent
The function of control is adjusted, it is achieved that the utility model level is all referring to the invention to the phased speaker system of subregion.
All referring to the phased speaker system of subregion, signal is input into level from input interface module 11, via preamplifier
Module 12 is amplified, and amplifies the electric signal input power amplifier module 13 of enough signal to noise ratios, the power amplifier module
13 electric signal via the output of phased partition hander 14 to level all referring to the phased loudspeaker 15 of subregion so that constitute one it is complete
Whole electroacoustic processing system.
Above is preferable implementation of the present utility model is illustrated, but the utility model is created and is not limited to be implemented
Example, those of ordinary skill in the art can also make various equivalent variations or replace on the premise of without prejudice to the utility model
Change, these equivalent variations or replacement are all contained in the application claim limited range.
