Fig. 3 is the structural schematic diagram of another multimedia audio equipment provided by the utility model.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to FIG. 1, Fig. 1 is a kind of structural schematic diagram of multimedia audio equipment provided by the utility model, more matchmakers
Body audio frequency apparatus includes:
Main audio processor and redundancy audio processor, the first audio input port of the main audio processor and the external world
Source of sound is connected, and the first audio output port is connected with playback equipment；Second audio input port of the redundancy audio processor
It is connected with the extraneous source of sound, second audio output port is connected with the playback equipment.
It should be noted that the part in Fig. 1 in dotted line frame is multimedia audio equipment provided by the utility model.Its
In, the first audio input port refers to all input ports on main audio processor, by taking Fig. 1 as an example, the first audio input
Port includes In 1, In 2, In 3, In 4, and similarly, the first audio output port refers to all defeated on main audio processor
Exit port, the first audio output port includes Out 1, Out 2, Out 3, Out 4 in Fig. 1.Herein for extraneous source of sound and broadcasting
The type and corresponding data mode etc. for putting equipment are not construed as limiting, and playback equipment can be sound equipment, recorded broadcast equipment etc., are such as schemed
Shown in 1, which includes simultaneously sound equipment and recorded broadcast equipment, naturally it is also possible to and it is any one of them, it specifically should be more according to this
The specific application environment of media audio equipment makees corresponding configuration.
It should be noted that the main audio processor and redundancy audio processor in multimedia audio equipment may each comprise
Multiple input ports and multiple output ports, are not specifically limited herein, with four input ports and four output ports in Fig. 1
For multimedia audio equipment provided by the utility model is illustrated.
The utility model is intended to illustrate that redundancy audio frequency apparatus needs to be respectively connected with extraneous source of sound and playback equipment, right at this
It is not construed as limiting in specific connection type.Preferably, the application provides three kinds of connection types herein:
The first connection type as shown in Figure 1, the second audio input port of the redundancy audio processor pass through it is described
First audio input port is connected with the extraneous source of sound.Second audio output port passes through first audio output
Mouth is connected with the playback equipment.
After audio analog signals are transmitted to main audio processor by i.e. extraneous source of sound, by main audio processor by audio frequency simulation
Signal is sent to redundancy audio processor, at this point, actually main audio processor is connected with redundancy audio processor, and redundancy
Audio processor and extraneous source of sound are not connected directly.
Second of connection type is as shown in Fig. 2, Fig. 2 is the knot of another multimedia audio equipment provided by the utility model
Structure schematic diagram, extraneous source of sound each at this time are set simultaneously there are two audio output port, are respectively used to connection main audio processor
Second audio input port of the first audio input port and redundancy audio processor.
The third connection type is as shown in figure 3, Fig. 3 is the knot of another multimedia audio equipment provided by the utility model
It is connected after structure schematic diagram, first audio input port and the second audio input port doubling with the extraneous source of sound,
It is connected after first audio output port and the second audio output port doubling with the playback equipment.
It should be noted that being different from input port, the output port of main audio processor and redundancy audio processor is simultaneously
It is not attached to, but is directly connected with playback equipments such as sound equipments.Therefore, output port, only Fig. 1 and two kinds of Fig. 2 connections are directed to
Mode, the first main audio processor as shown in Figure 1 with after the output port doubling of redundancy audio processor with playback equipment phase
Even, second of main audio processor as shown in Figure 2 is connected with playback equipment respectively with the output port of redundancy audio processor.
Actually extraneous source of sound is also to be connected simultaneously with main audio processor and redundancy audio processor at this time, is different from the
Two kinds of connection types, extraneous source of sound at least only needs an audio output port at this time, and cable is divided into two and connects respectively at this time
The first audio input port of main audio processor and the second audio input port of redundancy audio processor are connect, that is, uses doubling
The mode of connection, audio analog signals are divided into two.In general, first accessing main audio processor, then access redundancy audio processing
Device.
Based on the above embodiment, as preferred embodiment, when the main audio equipment works, the redundancy audio frequency apparatus
Port switch disconnect, the port switch is for controlling second audio input port and second audio output port
In mute state.
It is understood that redundancy audio processor is needed in main audio equipment in order to achieve the purpose that system hot standby is used
Open state is kept after booting.But it in order to avoid meeting-place acoustic echo and problem of uttering long and high-pitched sounds, needs the institute of redundancy audio processor
There is port to be maintained at mute state.
Certainly, it once main audio processor breaks down, at this time without keeping mute state, can use at redundancy audio
It manages device to work instead of main audio processor, and can be chosen whether according to the fault degree of main audio processor will be at main audio
The all of the port of reason device is set as mute state.
Based on the above embodiment, as preferred embodiment, the multimedia audio equipment can also include:
Master-slave swap key set on multimedia audio device housings surface, for switching the main audio processor
With the working condition of the redundancy audio processor.
Which kind of connection type no matter is used, master-slave swap key can be set in multimedia audio device outer surface, use
In manual switching main audio processor and redundancy audio processor, the one key switching of primary/standby devices is realized.
Specific case used herein is expounded the principles of the present invention and embodiment, above embodiments
Explanation be merely used to help understand the method and its core concept of the utility model.It should be pointed out that for the art
For those of ordinary skill, without departing from the principle of this utility model, several change can also be carried out to the utility model
Into and modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
