Abstract
The utility mode relates to a sound console with a U S B sound card, which is characterized in that the sound console is provided with a U S B sound card, wherein audio output signals of the sound console are output into the audio signal input end of the sound console after passing through an optional amplifier, audio output signals of the U S B sound card are output to the audio signal input end of the sound console after passing through another optional amplifier, the U S B sound card is connected with a computer through a U S B interface. The U S B sound card adopts a C M 108 chip, and the optional amplifier adopts B A 4510 F, also uses optional amplifiers with J R C 4558 D and T S 923. The utility model has the beneficial effects of reducing the number of connecting wires between the computer and the sound console, reducing the interferences of sound signals in the transmission process, and increasing the transmission quality of sound.
Description
Technical field
The utility model relates to a kind of sound console of the USB of having sound card.
Background technology
The application of sound console is more and more, and sound console is of a great variety, and the various interface of sound console is more, debug process is complicated, needs to connect various tone frequency channel wires.So, influence the transmission quality of voice signal because sound is the interference that analog signal is easy to be subjected to other signal.
The utility model content
The purpose of this utility model has provided a kind of sound console of the USB of having sound card, solved that traditional sound console various interface is more, debug process is complicated, need to connect the problem of various tone frequency channel wires, and analog signal is easy to be subjected to the interference of other signal, influences the technical problem of the transmission quality of voice signal.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of sound console of the USB of having sound card, it is characterized in that: sound console is provided with a USB sound card, the audio output signal of sound console exports the audio signal input end of USB sound card after by an operational amplifier to, the audio output signal of USB sound card exports the audio signal input end of sound console after by another operational amplifier to, and the USB sound card is connected with computer by USB interface.
Described USB sound card adopts the CM108 chip.
Described operational amplifier adopts BA4510F, also can use amplifier chips such as JRC4558D and TS932.
Need pass to the sound of computer, handle and be transferred to computer by the usb data line by USB sound card chip.The sound that computer is released is handled through USB sound card chip, and transfers to sound console, makes the people can hear the sound that computer is released by audio amplifier again.
The beneficial effects of the utility model are: reduced the quantity of the connecting line between computer and the sound console, to the interference of voice signal, improved the transmission quality of sound in the minimizing transmission course.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of sound console with USB sound card, as shown in the figure, sound console is provided with a USB sound card (CM108 chip), with being connected of sound console.Sound from sound console is come after the suitable amplification by operational amplifier 1, is transferred to the sound input pin of CM108, and then the internal conversion of process CM108 is that digital signal is transferred to computer by USB with analog signal conversion.The sound that computer is released is converted to analoging sound signal through the inter-process of CM108 with digital audio signal, and the pin of output sound is connected with operational amplifier 2, and voice signal is carried out suitable amplification, exports audio amplifier again to.Described operational amplifier 1,2 adopts BA4510F, also can use amplifier chips such as JRC4558D and TS932.
Sound console mainly is the transportation simulator voice signal, is vulnerable to the interference of other signal.Therefore be that digital signal is transmitted with analog signal conversion, can reduce the interference of signal, guarantee signal transfer quality, reduce distortion.
