Abstract
The utility model relates to a three-in-one audio transmission control system, which mainly comprises an audio controller, a network adapter, a network wireless terminal, an audio and a wireless host, wherein the audio controller is connected with the network adapter, the network adapter is connected with a LAN (local area network) through a network, the network wireless terminal is connected with the LAN through wireless signals, the wireless host is connected with the network wireless terminal through wireless signals, and the network wireless terminal is connected to the audio. Compared with a traditional audio system, the three-in-one audio transmission control system is more advantageous in flexibility, convenience and safety.
Description
Technical field
The utility model relates to a kind of sound system transmission control field, especially a kind of traditional analogue audio frequency technology, digital network Audiotechnica and digital radio Audiotechnica are organically merged, brand-new three-in-one audible transmission control system is finally constructed out in the parallel running in same sound system with three kinds of signals and standard passage.
Background technology
With regard to function, the basic function of sound system is exactly the transmission of signal, control and amplification.No matter be professional user or unprofessional user, its basic demand has two, and first is exactly effective; Second is exactly easy to use.Satisfy user's demand, system integrator must carry out the work of three aspects (stage): (1) functional planning, system's design and lectotype selection; (2) training is installed, debugs and used in system; (3) after-sales service and do necessary transformation and upgrade according to user's request.
The Sound Engineer will make up a new sound system, or according to user's request old system is carried out necessary transformation and upgrade, the problem that must solve is exactly signal transmission and the control of system, if the pipe engineering difficulty is very big, the unallowed words of perhaps construction and decoration condition, all work all can't be carried out.The tradition sound system uses the physics cable to connect, therefore can often run into above-mentioned on aspect the pipelining insurmountable problem.Along with the develop rapidly of digitizing technique, modern sound systems realizes that by network digitlization transmission and control have become main flow trend, this for the engineer provide one not only convenient but also have means of power.In addition, in some specific public address occasion, adopt the digital radio transmission technology then to have unrivaled convenience advantage.
The transmission means of above-mentioned three kinds of sound systems all cuts both ways, and usually, the engineer need decide according to actual conditions and takes which kind of method to be only best solution.
The utility model content
In order thoroughly to solve above-mentioned many defectives and inconvenience, solve the whole demands of user aspect sound equipment substantially, the utility model provides a kind of three-in-one audible transmission control system, and it is that digital network technology, radiotechnics, professional sound equipment and public broadcasting technology are integrated comprehensively.
The technical scheme that its technical problem that solves the utility model adopts is: three-in-one audible transmission control system mainly comprises acoustic controller, network adapter, network wireless terminal, sound equipment, wireless host, described acoustic controller is connected with network adapter, acoustic controller is delivered to network adapter with the transmission form of analog signal after all kinds of sound source signals are mixed.Network adapter becomes analog-signal transitions digital signal and LAN by network connection again, and the network wireless terminal is connected by wireless signal with LAN, and the network wireless terminal is connected to sound equipment.
Wireless host with three-dimensional source of sound and microphone speech level mixed processing after, can be connected with the network wireless terminal by wireless signal.
The network wireless terminal can convert network digital signal and digital wireless signal to the analog line signal, and this signal will enter built-in power amplifier or directly do circuit output.
The beneficial effects of the utility model are: three-in-one audible transmission control system and tradition relatively have more flexibility, convenience and security advantages.Digitizing technique can make systemic-function more powerful and comprehensive, simultaneously, its operation is equally convenient easily just like using " home audio ", thoroughly change the hard nut to crack of " professional sound equipment " complicated difficult usefulness, based on the fusion of sound equipment and computer networking technology, system can develop powerful management software (broadcast management, Real-time Monitor Management etc.).In the design of function of use, breaking traditions about " professional sound equipment ", " multimedia conferencing ", " teaching, training ", " background music " and " public broadcasting " etc. fully is mutual uncurrent segmentation field in the past.The user only need make up a cover sound system, can realize multipurpose truly, not only creation of value maximization, but also saves cost for the client.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the fundamental diagram of three-in-one audible transmission control system.
1. acoustic controllers among the figure, 2. network adapter, 3.LAN, 4. network wireless terminal, 5. sound equipment, 6. wireless host.
Embodiment
As shown in Figure 1, after by acoustic controller (1) stereo source of sound and microphone speech level being mixed, deliver to network adapter (2) with the transmission form of analog signal.After carrying out A/D conversion via network adapter, digital signal level is carried out the compiling of TCP/IP communications protocol, and the Packet after this compiling is broadcasted whole LAN (3) through network connection.
Network wireless terminal (4) is not having to be in the standby state under the situation about connecting with network adapter (2), and is similar to the holding state of domestic television set.Receiving when sending to the Packet of LAN (3) from network adapter (2), network wireless terminal (4) can be opened power amplifier power supply, enters normal communication operating state.To receive by built-in TCP/IP communications protocol and comprise " Packet of lossless audio " from newly being interpreted as harmless digital audio and video signals, and carry out the D/A conversion in inside.Simulated audio signal after converting carries out power amplification in this equipment, directly export audio amplifier (5) to.
Equipment under this pattern is operated on the frequency range of 2.4G, wireless host (6) with three-dimensional source of sound and microphone speech level mixed processing after, carry out A/D conversion in inside, after additional tetrad carried out data encryption then, the module by 2.4G sent.
When network wireless terminal (4) receives the signal of wireless host (6), at first tetrad is carried out address decoder, just can enter operating state at the identical situation lower network wireless terminal (4) of coding and open power amplifier power supply, the simulated audio signal after built-in power amplifier amplifies directly exports audio amplifier (6) to.
Claims (3)
1. three-in-one audible transmission control system, it mainly comprises acoustic controller, network adapter, network wireless terminal, sound equipment, wireless host, it is characterized in that: described acoustic controller is connected with network adapter, network adapter and LAN are by network connection, and the network wireless terminal is connected by wireless signal with LAN.
2. three-in-one audible transmission control system according to claim 1, it is characterized in that: described network wireless terminal is connected to sound equipment.
3. three-in-one audible transmission control system according to claim 1, it is characterized in that: described wireless host is connected by wireless signal with the network wireless terminal.
