Abstract
The utility model relates to a sound card, in particular to a PCI (Peripheral Component Interconnect) sound card with an echo cancellation effect. The PCI sound card comprises audio processing chips integrated on the sound card, wherein the audio processing chips include a data processing module used for converting PCI data into 12S data, an audio coder and decoder used for converting the 12S data into an analog sound signal, an echo cancellation chip used for performing echo cancellation on the analog sound signal, and an echo cancellation algorithm memory chip, which are connected in sequence, wherein the echo cancellation chip is connected with an input/output interface. According to the utility model, the echo cancellation processing chip and the echo cancellation algorithm memory chip are integrated on the PCI sound card, the effect of integrating software and hardware is achieved to cancel the echo, the tone quality is ensured, and the voice effect of a computer is improved.
Description
Technical field
The utility model relates to a kind of sound card, especially a kind of PCI sound card.
Background technology
Along with continuous progress in science and technology; Computer technology and network information development are rapidly; Make that speech communication obtains constantly popularizing; As in the chat of all kinds of computer speechs, the sub-district between the owner or the voice between owner and the estate management are linked up, between the large-scale employee of intra-company or the voice between leader and the employee link up more and more and promote, so calling quality need be protected.Yet the common PCI sound card that uses in the active computer; Receive the power supply radiation interference easily in computer-internal, can influence the tonequality of sound card output audio signal, especially when carrying out conversation voice or listening to the music; Echo be can produce, sound effect and talk mood influenced.
Summary of the invention
The utility model provides a kind of and can eliminate echo in order to solve defective and the deficiency that above-mentioned prior art exists, and guarantees tonequality, improves the PCI sound card of computer speech effect.
The technical scheme of the utility model: a kind of PCI sound card with the echo effect that disappears; Comprise the Audio Processing chip; Said Audio Processing chip comprises: one is used for that data processing module that pci data just transforms into the I2S data, one be used for the I2S data conversion is that the audio codec, of simulated audio signal done disappear echo chip and echo algorithm stores chip that disappears that the echo that disappears is handled to simulated audio signal; Described data processing module, audio codec, the echo chip that disappears are connected with the echo algorithm stores chip that disappears in order, and the echo chip that disappears connects IO interface.
Preferably, described data processing module adopts the CA0106 chip.
Preferably, described audio codec adopts the WM8772 chip.
Preferably, the described echo chip that disappears adopts the CX20707 chip.
Preferably, described IO interface adopts the DB9 socket.
The utility model echo process chip that will disappear is integrated on the PCI sound card with the echo algorithm stores chip that disappears, and reaches the effect of software and hardware combining, makes it can eliminate echo, guarantees tonequality, improves the computer speech effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection domain.
As shown in Figure 1; A kind of PCI sound card with the echo effect that disappears; Comprise the Audio Processing chip that is integrated on the sound card; Said Audio Processing chip comprises: one is used for that data processing module that pci data just transforms into the I2S data, one be used for the I2S data conversion is that the audio codec, of simulated audio signal done disappear echo chip and echo algorithm stores chip that disappears that the echo that disappears is handled to simulated audio signal; Described data processing module, audio codec, the echo chip that disappears are connected with the echo algorithm stores chip that disappears in order, and the echo chip that disappears connects IO interface.
Data processing module in the utility model is the CA0106 chip, and it transforms into the I2S data with pci data; Audio codec is the WM8772 chip, is the CODEC of an audio frequency, and it is analog input output with the I2S data conversion; The echo chip that disappears is the CX20707 chip, and it carries out phonetic entry output relatively to ASH, thereby reaches the effect of the echo that disappears.The DB9 socket is adopted in the audio frequency input and output, has so both improved the interference free performance of signal, has avoided general COBBAIF contact to use oxidation for a long time again and causes the phenomenon of loose contact.
The utility model uses also very convenient, and sound card is installed in the pci card groove on the standard computer main board, refills with special use to drive, and the user can the enjoy high quality music and network dialogue clearly.
