Abstract
The utility model provides a sound image localization trails round table conference system, with spokesman's microphone and all around the directional loudspeaker form space transition system, through digital media matrix according to the microphone subregion, divide into groups to correspond the public address of orientation for place speaker, make the spokesman in case the speech, sound can be automatic from oneself nearest audio amplifier public address.
Description
Technical field
The application belongs to electroacoustic field, particularly to a kind of sound reinforcement system for meeting.
Background technology
Be presently used in the sound reinforcement system of relatively large roundtable conference, the arrangement of speaker more single so that acoustic image
Inconsistent with the physical location of talker so that audience cannot know who speech, affect participant effect.
Utility model content
In order to overcome above deficiency, propose a kind of Sound image localization and follow the tracks of conference amplifying system, in the feelings ensureing certain loudness
Under condition, also increase Sound image localization function so that when participant participates in meeting, preferably definition can not only be obtained, also can
Enough positions knowing talker at once, thus make high-end meeting-place public address demand.
A kind of Sound image localization is provided to follow the tracks of roundtable conference system, including the multiple conference microphones being positioned on conference table, its
The acoustical signal of speaker is converted to the signal of telecommunication input to the Digital Media matrix on backstage；Digital Media matrix is stored with correspondence
Geocoding in each conference microphone；In advance conference microphone is divided into by n group according to microphone position, by corresponding for microphone address
Packet belonging to coding is also stored in Digital Media matrix, and each group is corresponding to a directional loudspeaker；Digital Media matrix
After cylinder signal if receiving being digitized process, packet according to belonging to the address code of this microphone obtains this microphone, and
Digital signal after processing is exported and is exported to the corresponding directional loudspeaker of this subregion.
Further, directional loudspeaker is located near its corresponding microphone packet, is preferably the upper of its corresponding microphone packet
At square ceiling.
Further, in conference table centre position, preferably at ceiling, arrange a locating speaker, its also with digital matchmaker
Volume matrix is connected, and the directional loudspeaker co-ordination with surrounding, the sound of speaker is carried out public address simultaneously.
Brief description
The Sound image localization of Fig. 1 the application follows the tracks of conference amplifying system schematic diagram
Specific embodiment
In conjunction with accompanying drawing, the upright projection reflective optics of the application is described in detail.
As shown in Figure 1, the system includes the multiple conference microphones 1 being positioned on conference table, and it is by the sound of speaker
Signal is converted to the signal of telecommunication and inputs to the Digital Media matrix (not shown) on backstage；Digital Media matrix be stored with corresponding to
The geocoding of each conference microphone；In advance conference microphone is divided into by n group according to microphone position, corresponding for microphone address is compiled
Code belonging to packet be also stored in Digital Media matrix, each group corresponding to a directional loudspeaker 2, this directional loudspeaker 2
Near this group microphone, it is preferably at the ceiling above it；Digital Media matrix enters line number to cylinder signal if receiving
After wordization is processed, packet according to belonging to the address code of this microphone obtains this microphone, and by the digital signal after processing export to
The corresponding directional loudspeaker of this subregion 2 is exported.So that spokesman is once talk, sound can be automatically from nearest from oneself
Audio amplifier public address.
Further embodiment, preferably at the ceiling of top, can arrange locating speaker 3 in the middle of conference table, its
Also it is connected with Digital Media matrix, and directional loudspeaker 2 co-ordination with surrounding, the sound of speaker is expanded simultaneously
Sound, prevents from causing meeting-place sound too small due to single directional loudspeaker 2 public address that is to say, that increasing the same of Sound image localization
When, improve sound intensity.
It will be appreciated by those skilled in the art that can rationally be deformed to the application as the case may be, also belong to this
The protection domain of application.
Claims (5)
1. a kind of Sound image localization follows the tracks of roundtable conference system, and including the multiple conference microphones being positioned on conference table, it will be spoken
The acoustical signal of people is converted to the signal of telecommunication and inputs to the Digital Media matrix on backstage；Digital Media matrix is stored with corresponding to each
The geocoding of conference microphone；In advance conference microphone is divided into by n group according to microphone position, by corresponding for microphone geocoding institute
The packet belonging to is also stored in Digital Media matrix, and each group is corresponding to a directional loudspeaker；Digital Media matrix is to reception
To microphone signal be digitized processing after, packet according to belonging to the address code of this microphone obtains this microphone, and processing
Digital signal afterwards exports and is exported to the corresponding directional loudspeaker of this packet.
2. Sound image localization as claimed in claim 1 follows the tracks of roundtable conference system, wherein directional loudspeaker if it corresponds to
