In the real work, audio signal enters pre-process module 10 by input 11 and arrives volume adjusting module 20 again, is used to promote local loud speaker 51 (alt) and the coding wireless output in back simultaneously.Because volume adjusting module has coding at the size of volume, so the wireless audio signal that obtains by transmitter module 30 does not singly include the whole tone frequency information of spectrum again and again, information volume is also arranged, this makes receiver module 40 can handle this information volume, to such an extent as to when regulating the volume of local loud speaker 22, the volume of outer loud speaker 51 can positive correlationization, and do not need independent operation.Be set to synchronous variation in this example.
Embodiment two:
As Fig. 2, the utility model embodiment two schematic diagrames.Compare with embodiment one, local audio module 100 in this example, outer playback frequency module 200 all has similar structure.Different is, also has one and shake control receiving system 62 in local audio module 100, and this shakes remote controller 61 controls that control receiving system 62 is subjected to a coupling, and changes the especially settings of volume adjusting module part of local audio module 100.Remote controller 61 is communicated by letter as signal vehicle with infrared ray with shaking control receiving system 62, and the equipment that is positioned at remote controller 61 at a distance can be adjusted synchronously by the remote-receiver 62 final volumes of entire mechanism that realize.
Embodiment three:
As shown in Figure 3, the utility model embodiment three schematic diagrames.Compare with embodiment two, its local audio module class seemingly and also comprises an outer volume adjusting module 52 in the playback frequency module 200 outside, and this outer volume adjusting module 52 can be done two kinds of following settings:
A kind of is the volume of the outer loud speaker 51 of independent control, independently superposes mutually with the regulation mechanism that originally was limited by local audio module 100.After the volume of adjusting this locality when local audio module 100 and putting outward, the playback frequency module can also be regulated the volume ratio of outer loud speaker 51 on this basis by outer volume adjusting module 52 outside.
Another kind has been expanded the function of outer volume adjusting module 52, promptly by changing the setting of outer volume module 52, makes outer playback frequency module 200 reverse control local audio modules 100, reaches this locality and outer playback amount and changes synchronously.This just makes outer playback frequency module 200 have the function of shaking control.
Embodiment four:
As shown in Figure 4, the utility model embodiment four schematic diagrames.In this example, local audio module 100 is arranged in a TV set device 1, and input 11 inserts the audio signal of this TV set device 1.Volume adjusting module 20 connects loud speaker L channel 23 and R channel 22 separately by two local outputs.Outer playback frequency module 200 has two, and one of them comprises receiver module 40a, outer amplifier 50a and the rearmounted L channel 51a of outer loud speaker, rearmounted R channel 51b.Another comprises receiver module 40b, outer amplifier 50b and the mid-51c of outer loud speaker.In the real work, the emission of local audio module comprises the wireless signal of the frequent spectrum information of whole tone, mode playback frequency module 200 receptions outside by broadcasting, handle each channel information respectively by separately outer amplifier 50a and 50b, outer loud speaker via diverse location amplifies, realization around stereophonic effect, simultaneously when regulating the volume of TV set device 1, but the volume synchronous change of all surround sounds.
Embodiment five:
As shown in Figure 5, the utility model embodiment five schematic diagrames.Compare with embodiment one, the transmitter module 30 in this embodiment local audio module 100 is handled from the signal in the volume adjusting module at wired mode; Transmitter module has a wired output interface 31, by the receiver module 40 in the outer playback frequency module 200 of a cable 32 connections.That is, present embodiment adopts wired mode transmission signals fully.
Embodiment six:
As shown in Figure 6, the embodiment of the invention six schematic diagrames.Compare with embodiment five, in this example, the transmitter module 30 of local audio module 100 connects a wireless module 33 by its wired output interface 31; And the receiver module 40 in the outer playback frequency module 200 still adopts wireless mode to receive the signal of launching from wireless module 33.This scheme can be considered the band wireless extensions scheme with wired mode.Transmitter module 30 has the function of automatic identification, and when wired output interface 31 inserts wireless module 33, but the catv terminal of similar embodiment five constantly, and transmitter module 30 exportable voiceless sound amounts are regulated the signal of information; If what insert is wireless module 33, then activate the function that has the transmission of volume conditioning signal automatically.This is a design very easily, both can satisfy direct driving voice frequency terminal, can switch to the wireless mode of band synchronizing function again.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
