In order to the technical characteristic to utility model, object and effect have understanding clearly, now contrast accompanying drawing and embodiment of the present utility model is described, label identical in the various figures represents that structure is identical or structure is similar but the parts that function is identical.
In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, embodiment is interpreted as a kind of preferred or have more the technical scheme of advantage.
For making simplified form, only schematically show the part relevant to the utility model in each figure, they do not represent its practical structures as product.In addition, being convenient to for making simplified form understand, there are the parts of identical structure or function in some figure, only schematically depict one of them, or only having marked one of them.
Fig. 1 is in order to illustrate that multi-channel sound shelters the structural representation of a kind of exemplary embodiment of device.As shown in Figure 1, multi-channel sound is sheltered device and is comprised a main frame 10 and a plurality of terminal module 20.Each terminal module 20 refers to Fig. 2 with the annexation of main frame 10.
As shown in Figure 2, each terminal module 20 comprises a sound receiver 24, sound capturing unit 26 and an audio player 28.Wherein.
The sound of user can be converted to voice signal S3 by sound capturing unit 26, and it can be microphone or vibro-pickup.
Sound receiver 24 is such as a sound isolating earphone, the sound receiver 24 of terminal module 20 shown in figure can be connected with sound capturing unit 26 audio frequency of other-end module 20, and the sound capturing unit 26 of terminal module 20 shown in figure can be connected with sound receiver 24 audio frequency of other-end module 20.
Audio player 28, it can be a loudspeaker.
As shown in Figure 2, main frame 10 comprises a speech selection switch 12, storer 14 and a signal processor 16.Wherein,
The exportable language selection command S1 of speech selection switch 12, it can be a hand switch on main frame 10, is operated by operator.
Multiple language storage unit is stored in storer 14, a plurality of voice undesired signal S2 is stored in each language storage unit 142, voice undesired signal S2 in each language storage unit 142 can distinguish according to category of language, language environment, category of language such as by language storage unit 142 store the voice undesired signal be made up of Chinese, by language storage unit 142 store the voice undesired signal be made up of Korean, certainly can also carry out the separation of more refinement according to country dialect.Language environment such as has the voice undesired signal on simulation square, has the voice undesired signal at simulation station.According to the difference that design needs, the voice undesired signal that each language storage unit 142 stores also can be different.Storer 14 can export the voice undesired signal S2 of corresponding language storage unit 142 according to language selection command S1.
Signal processor 16, such as arm processor, coder (CODEC) etc. comprise first signal processing unit 162 and secondary signal processing unit 164, the first signal processing unit 162 is connected with sound capturing unit 26 signal.Secondary signal processor 164 is connected with storer 14 signal.Voice signal S3 can be divided into multiple little paragraph by the first signal processing unit 162, then by these little paragraph random combines, generates a first masking signal S4.Secondary signal processing unit 164 can produce a second masking signal S5 by after voice undesired signal S2 random combine.
The audio player 28 of each terminal module 20 can be connected with the first signal processing unit 162 and secondary signal processing unit 164 signal respectively, it broadcasts after the first masking signal S4 can being generated the first masking sound, broadcasts after the second masking signal S5 is generated the second masking sound.
Above-mentioned multi-channel sound is sheltered device and can be used in a meeting, host and participant everyone use a terminal module, link up conference content by sound receiver 24 and sound capturing unit 26 between everyone.Before meeting starts, host can according to information such as the category of language of participant, language environments in main frame 10 operating language selector switch, output language select command.Storer 14 exports the voice undesired signal S2 of corresponding language storage unit 142 according to this language selection command S1.Second processing unit 164 of each terminal module generates the second masking signal S5 by after those voice undesired signal S2 random combine, and broadcast after generating the second masking sound by audio player 28, in certain limit around everyone, everyone sound of speaking can be covered by the second masking sound, make cannot understand conference content away from other people of host or participant's certain limit, even if adopt sound pick-up outfit also can record masking sound and cannot not hear, and by sound receiver 24 and sound capturing unit 26, conference content clearly can be received between host and each participant.While conference speech person loquiturs and sounds, sound capturing unit 26 sound of this can being spoken is converted to voice signal S3, this voice signal S3 can be split random combine after multiple paragraph by the first signal processing unit 162, generate a first masking signal S4, and broadcast after first masking signal S4 being generated the first masking sound by audio player 28.First masking sound, the second masking sound cover sound of speaking simultaneously can improve masking effect further, and due to terminal module 20 can away from main frame 10, the conference content that can realize in any distance is maintained secrecy.In addition, because the first masking sound needs could generate after operator loquiturs, therefore the first masking sound is spoken can have delay relative to operator, and the second masking sound can be play at any time, compensate for the problems referred to above.
In embodiment shown in Fig. 2, audio player 28 is gone back signal and is connected to sound capturing unit 26, export a masking sound to audio player 28 while sound capturing unit 26 obtains voice signal S3 to give an order S6, broadcast the second masking sound to control audio player 28 or broadcast the first masking sound and described second masking sound simultaneously.Adopt in such a way, multi-channel sound can be made to shelter device and only send hidden sound when participant speaks.
As shown in Figure 3, the main frame 10 sheltering device at multi-channel sound also can comprise one can the recording device 16 of external storage equipment 30, recording device 16 can be connected with sound capturing unit 26 audio frequency of each terminal module 20, to enroll conference content, be stored on external storage equipment 30 after admission, improve confidentiality.
Be to be understood that, although this instructions describes according to each embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for possible embodiments of the present utility model; they are also not used to limit protection domain of the present utility model; allly do not depart from the utility model skill equivalent embodiments of doing of spirit or change; as the combination of feature, segmentation or repetition, all should be included within protection domain of the present utility model.
