Description
Technical field
The present invention relates to the field of amplifying, especially a kind of network wireless microphone with intelligent control function.
Background technology
Microphone, is English Microphone Chinese transliteration, is commonly called as microphone.It is the basic equipment in public address system,
Very important role is play, its major function is the extraneous voice signal of pickup, and is transmitted in public address system.Nothing
Line microphone, is exactly using wirelessly as its name suggests（Mainly frequency modulation）Equipment to transmit sound.
Traditional wireless microphone, is made up of the transmitting terminal and receiving terminal of wireless microphone, transmission means be it is unidirectional, i.e.,
Voice signal is passed to the receiving terminal of microphone by the transmitting terminal of wireless microphone.Moreover, what is wherein transmitted is only audio
Signal, not any control instruction.Comparatively, framework is relatively simple.
Traditional wireless microphone is one " information island ", be only limited to wireless microphone transmitting terminal and receiving terminal it
Between one-way communication, and communication also be audio.Whole sound reinforcement system can not be controlled by wireless microphone.
Traditional wireless microphone, be one closing system, it is impossible to Broadcasting Control software, Conference control software,
Audio control software etc. is realized and interconnected, and realizes data sharing, data processing, data control etc..
Traditional wireless microphone, it is impossible to support network, this allows for having certain limitation using distance, and scope is smaller,
Having surpassed certain wireless reception scope cannot normal work.
Traditional wireless microphone, does not support audio input and the audio mixing output of outside, can only realize wireless microphone
The audio of transmitting terminal collection is transmitted, all if desired for background music at some（BGM, BackGround Music）Scene is not
It is applicable.Audio, the ANTENNAUDIO of wireless microphone transmitting terminal simultaneously for multichannel outside input, local audio broadcast unit
The audio of output can not carry out the regulation such as high bass, balance, gain.
Traditional wireless microphone, can support multiple transmitting terminals, but between these multiple transmitting terminals be frequency
It is different, it can be sayed without any control instruction.
Therefore, design one kind being capable of intelligent control public address system, support network, the input of support external audio and audio mixing, branch
Hold the network wireless microphone of audio regulation, it appears particularly urgent.
Closest to the analysis and contrast of technology in the case of existing
At present, immediate technical scheme is in the case of existing：Application No. CN200680005323.3's《Wireless microphone system
System》（Hereinafter referred " documents 1 "）, Application No. CN200820079017.0《A kind of Digitalization network microphone》（Under
Literary referred to as " documents 2 "）.
Documents 1, documents 2 have all carried out certain improvement to traditional microphone system, and documents 1 are to increase
The function of sound and communications status that wireless microphone is monitored by wireless microphone transmitting terminal is added, documents 2 are then to increase
Digitlization and the network function of microphone are added.
Documents 1, Application No. CN200680005323.3's《Wireless microphone system》, the target of the invention is to carry
For a kind of wireless microphone system, it is not necessary to be connected to Wireless microphone receiver（Receiving terminal）Amplifier, loudspeaker etc., only
To pass through wireless microphone transmitter（Transmitting terminal）It just can simply monitor the state of sound, the communication of wireless microphone etc..
Documents 2, Application No. CN200820079017.0's《A kind of Digitalization network microphone》, mainly realize
Voice signal in microphone is switched into data-signal by microphone unit, signal processing unit, then passes through Ethernet
Interface unit carries out network transmission, and participation of the whole process without computer.
Documents 1 and documents 2 and the present invention are entirely different.
The content of the invention
The problem to be solved in the present invention.
The present invention is provided under background more than.It is an object of the present invention to provide a kind of wireless microphone, it both can be with intelligence
Public address system can be controlled, network can be also supported, more flexible, also support outside input and audio mixing, and support audio to adjust is controlled
Save function.
The technical scheme solved the problems, such as.
An aspect of of the present present invention is related to wireless microphone transmitting terminal, wireless microphone including that can communicate each other and connect
The network wireless microphone of receiving end and control software, the wireless microphone transmitter includes：Reusable button, instruction send single
Member, audio transmitting element.Also, the wireless microphone receiving terminal includes：Instruction reception unit, audio receiving unit, outside
Input block, local broadcast unit, automatic broadcast unit, audio output unit, audio adaptation unit, network processing unit, sound
Frequency memory cell, feedback action unit.Meanwhile, described control software includes：Multiterminal supporter, interconnect unit.
Another aspect of the present invention will be implemented function such as.
Public address system can be controlled by wireless microphone, includes the packet of switch, control device etc. of control device；
Due to supporting network, so wireless microphone can be placed on any one position, remote management is carried out by network；
The input of external audio can be supported and audio mixing is supported, so as to support more background musics etc. to need what audio mixing was exported
Scene；
It can be adjusted for the audio of single channel, while also supporting the entire gain regulation after audio mixing output；
The control instruction of multiple transmitting terminals can respectively be defined, so as to more neatly control public address system.
The advantage of the present invention.
It is of the invention to have very big difference with traditional wireless microphone system：First, it is realized for broadcast system
Control；Meanwhile, it supports network, can place it in the position of any support network transmission, and can realize remote control；
Secondly, it supports external audio input, regulation, audio mixing and storage, also supports ANTENNAUDIO, network audio, local audio；Again
Secondary, above-mentioned all audios can be carried out adjusting respectively, also support the entire gain regulation after audio mixing；Finally, it supports many
Individual wireless microphone transmitting terminal, and control instruction defined in multiple wireless microphone transmitting terminals can be different, so that more
Neatly control public address system.
Of the invention it is more easy that it is used compared with traditional wireless microphone, and connection is also relative simple, reduces
The cost of study and time.Non-specialized-technical personnel, left-hand seat and can also grasp quickly.
Due to supporting external audio input, a variety of audios are supported, SCVF single channel voice frequency regulation and audio mixing are also supported, can reduce need not
The redundance units such as balancer, the sound console wanted, so as to reduce the consumption of traditional mode of production material, and then can be substantially reduced
Production cost, reduces its price.
In public address system, wireless microphone dialogue is a very important problem, because they bear propagation
Mission and important task, are often particularly important when handling accident.The wireless microphone of the present invention, not only supports traditional nothing
The institute of line microphone is functional, and can realize above-mentioned function, is all very big profit for whole public address system
It is good.
