With information process unit etc..Data input of the virtual unit respectively with microphone, sign pen and background information processing system connects
Mouth is connected.Background information processing system includes the incoming interface of data, hind computation processing routine and data outgoing interface.3D
System, which is presented, in audio scene includes head mounted display, several playback control devices and several playback equipments.Wear-type
Display and playback control device are connected with the data outgoing interface of background information processing system, and playback equipment is controlled with playing
Equipment is connected.
Moreover, user needs in advance, selection needs to configure the virtual scene of 3D audios in virtual unit.
Moreover, the scene that described virtual unit is presented can be with sign pen operation association and interaction.
Moreover, the microphone is used for inputting audio material and input instruction information.
Moreover, the sign pen is used to draw the thing in visual movement locus or the scene presented with virtual unit
Product carry out interactive.
Moreover, when entering row information input, needing correctly to carry out according to predetermined form.
Moreover, for mistake input information, system can be reported an error in time.
Moreover, the data input of a variety of virtual units of the incoming interface compatibility of data.
Moreover, head mounted display has identical time shaft with playback equipment.
The 3D audio systems provided using the utility model, user can carry out real-time, interactive with virtual reality system, and
With following advantage：Simulation quality, opening, specific aim, independence and security.Dummy rules can be with the practical operation in reality
Specification is combined, so as to carry out virtual rehearsal etc. using the system.The nonuniqueness of input can make different by system
Response, the 3D videos generated in real time are combined with 3D audios can provide the user preferable virtual environment.

Fig. 2 is the background information processing system schematic diagram of the utility model embodiment.
System schematic is presented for the 3D audio scenes of the utility model embodiment in Fig. 3.
Fig. 4 is the system operating diagram of the utility model embodiment.
Embodiment
Technical solutions of the utility model are described in detail below in conjunction with drawings and examples.
Referring to Fig. 1 and Fig. 2, the technical solution of the utility model provides a kind of interactive 3D audio systems, including three sons
System：System is presented in external information input system, rear information signal processing system and 3D audio scenes.The composition of three subsystems and
Between functional relationship it is as follows：External information input system includes virtual unit, microphone and sign pen etc., according to different need
Want user that different typing modes may be selected.First, virtual unit plays the virtual scene of user's selection, virtual unit here
Including helmet-mounted display and Wearable etc..Then, user will have two ways to carry out relevant parameter typing.The first is
Using sign pen according to virtual scene track drafting, track is generated and shown with image in real time in Helmet Mounted Display；Second
It is that user is instructed using microphone input related voice.Many compatible ports increase the diversity of input mode, provide the user more
More options simultaneously simplify operation.Multi input mode coordinates original scene, and the place of different modes is carried out in follow-up 3D audio frequency processing systems
Reason.
Further, user selects virtual scene on virtual unit, and scene is shown by video player.
Further, when using sign pen or microphone, user, which should try one's best, reduces unrelated action, to ensure typing information
For useful information.
Further, sign pen and its track drafting also can be in virtual scenes with image instant playback.
Further, the instruction of microphone input is simple, the fixed instruction set in advance.
When it is implemented, virtual unit can use wireless device.Mini microphone can be used to be arranged on signal for microphone
On pen, sign pen matches somebody with somebody functional switching push button.Two kinds of Data Enter modes can not be carried out simultaneously.
Then, the data of typing are inputted background information processing system by external information input system by the incoming interface of data
System.Background information processing system includes the incoming interface of data, hind computation processing routine and data outgoing interface.Hind computation
Processing routine is analyzed the parameter of sign pen typing, and audio file is generated according to signal parameter.Meanwhile, hind computation processing
Program be additionally provided with other program compatibility ports, so as to the expansion of follow-up function.
Further, the data input of a variety of virtual units of the incoming interface compatibility of data.
Further, background information processing system connection audio database, can select to form different audios according to user.
