It is connected with the DATA IN terminal of processing unit with the decoding, the decoding is received with processing unit and connect through the numeral input
The digital audio and video signals that send over of mouth, and simulated audio signal is generated after carrying out decoding conversion, connect through LineOut outputs
Mouth output.
Further, the LineOut output interfaces are LineOut 3.5mm or welded type output interface.
Further, the digital input interface includes Lighting interfaces, USB Type-C interfaces, Micro USB
In Type-A interfaces, Micro USB Type-B interfaces, USB Type-A interfaces, Mini USB Type-B interfaces at least two
Kind,
Further, the audio switching device also includes power circuit, for being provided with processing unit for the decoding
Power supply.
Further, the decoding and processing unit are protocol conversion chip.
Compared with prior art, advantage of the present utility model and good effect are：Audio switching device of the present utility model,
It is input into except conventional USB interface is supported, additionally it is possible to support the interface emerging at present such as input of Lightning interfaces, USB Type-
C interface is input into, and the data signal that above-mentioned interface is input into is converted into being based on by the decoding process of internal audio frequency circuit
The analog music output of LineOut forms, had so both realized being continuing with for old equipment, while also utilizing new digital skill
Art, provides the user the music of high-quality.Additionally, having saved the related resource of consumer and society, it is unlikely to related audio
Equipment is invested again.
After the detailed description of the utility model implementation method is read in conjunction with the figure, other features of the present utility model and advantage
Will become clearer.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the LineOut output audio switching devices of the various digital input interfaces of support that the utility model is proposed
A kind of embodiment functional-block diagram.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment one, audio conversion is exported the utility model proposes a kind of LineOut for supporting various digital input interfaces
Connection device, as shown in figure 1, including several digital input interfaces, decoding and processing unit and LineOut output interfaces, if
The dry communication terminal of digital input interface is connected with the decoding with the DATA IN terminal of processing unit respectively, the decoding
The digital audio and video signals that are sended over through the digital input interface are received with processing unit, and generate mould after carrying out decoding conversion
Intend audio signal, exported through the LineOut output interfaces.Wherein, decoding can use protocol conversion chip with processing unit
Realize, be capable of identify that interface protocol, the interface protocol of USB for such as meeting iAP2, be respectively used to identification Lighting interfaces and
USB interface, once identification is completed, audio switching device indicates oneself for slave unit, then provides power supply and numeral by main equipment
Audio signal, slave unit obtains power supply and is adjusted to required voltage and used with processing unit to decoding, while DAB
Signal be conveyed to decoding and processing unit, by decoding with processing unit complete audio decoder and power amplification, after the completion of pass through
LineOut output interfaces export analog signal.The audio switching device of the present embodiment realizes the various inputs of support, can access
