Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of digital effecter with effect update functions as shown in Figure 1, includes
One input pre-process circuit is used for the simulated audio signal input of electric guitar is optionally amplified and filtering;
One A/D change-over circuit is connected with the input pre-process circuit, is used for simulated audio signal is converted into digital signal;
One DSP computing and control module is connected with the A/D change-over circuit, be used for the digital signal of input is handled, and to the selection and the control of signal processing method;
One D/A change-over circuit is connected with DSP computing and control module, is used for the digital signal after handling is converted to simulating signal;

One FLASH ROM reservoir is connected with DSP computing and control module, is used to store the relative program of dsp processor;
One USB interface is connected with DSP computing and control module, is used for the exchanges data between dsp processor and external unit.
This digital effecter to the Audio Signal Processing process is: the simulated audio signal that electric guitar produces enters the input pre-process circuit, through optionally amplify and filtering after, become digital signal through high sampling rate A/D digital-to-analog conversion.The program that is chosen in the middle of the dsp chip by control module will be carried out multiple algorithm process, for example: overload, distortion, method waits the audio selection now; Intermediate frequency, high frequency, tone colors such as low frequency promote and reduce, and through the D/A change-over circuit digital signal after handling are converted to simulating signal then, carry out the output of audio frequency by final stage analog output signal treatment circuit at last.
The user can connect the internet by computer earlier, from internet or upgrading CD, download the refresh routine of effect device correspondence earlier, with the USB connecting line effect device is connected with computer, the effect device power supply is inserted, double-click refresh routine then, after but the DSP refresh routine converts the code of programming to automatic decompress(ion) and by DSP code converter intrinsic among the FLASH, be installed in the middle of the FLASH chip of user's effect device, after the last computer attention program successful installation, the user can pull out the USB wiring, carries out the on probation of effect device tone color.
The utility model major technology characteristics comprise following three aspects:
1) digitizing effect device circuit design
The single audio of DSP digitized processing function ratio conventional analog circuits class effect device is very different, and can have several in a digitizing effect device or tens kinds of different audios.For example a mimic channel distortion class effect device can only provide a kind of audio, distortion, method now, overloads etc. are a kind of, and we can obtain same multiple audio in this digitizing effect device, distortion, method now, overloads etc. are multiple, the utility model uses the A/D of high sampling rate aspect the simulating signal sampling, the D/A chip, so strengthened the validity of simulating signal to a great extent, the DSP algorithm processor adopts distinctive algorithm routine in addition, at audio details and each link frequency, approaching on the method for controlling operation thereof with the mimic channel effect device, therefore the user can readily appreciate that how to adjust, volume is little simultaneously, dirigibility is big, function is many, has possessed the incomparable advantage of simulation class effect device.
2) renewable function of DSP algorithm routine and USB program download interface design
The digitizing effect device DSP algorithm routine that the DSP algorithm routine of the utility model effect device is different from the past mainly is to be that this algorithm routine has renewable property, that is to say and can upgrade.We can be understood as the software upgrading of carrying out under the situation that hardware does not change from the principle, are exactly the upgrading of hardware and the lifting of performance in fact from audio.Write the FLASH chip at the DSP algorithm routine of a lot of digitizing effect devices in the past before being to dispatch from the factory, it is a kind of immobilized algorithm routine, program can not be read out also and can not be written into, the back user can not carry out that thereby the renewal of algorithm routine can not obtain to upgrade, more perfect, high emulation guitar audio more by any instrument, any interface or any website dispatching from the factory, original audio that the user that can say so can only the result of use device itself possesses, the adjustability scope can not be widened, and audio also can not get upgrading simultaneously.The characteristic of the DSP algorithm routine of this novel effect device and function are complete digitizing effect device DSP programs different from the past, its principal feature is exactly that the DSP algorithm routine can repeat to write, the user uses original audio algorithm routine to carry out the processing of audio after purchasing machine, when the user obtains DSP algorithm refresh routine by internet or audio upgrading CD, the user can utilize instruments such as USB interface, USB line, computer carry out the DSP algorithm routine repeat write, just upgrade and upgrade, its operating process also is very simple.Effect device after the upgrading is because the up-to-date DSP algorithm routine that is written in the FLASH chip, no matter still all new variation will be arranged on audio is handled from algorithm, so the user can obtain well repayment and more practicality.Usb function of the present utility model mainly is the renewal that is used for the dsp chip algorithm routine, the user downloads up-to-date this type DSP algorithm routine on demand earlier from the website or the program upgrade CD, use USB interface that this effect device is connected with computer then, the program of downloading is an executable file, the user only need double-click program and just can install automatically, and using method is very simple.After program installed, former DSP algorithm routine was updated or increases new algorithm and audio function, thereby the user has just had multiple up-to-date guitar audio.This USB program updates function has broken through the shortcoming of the intrinsic algorithm routine of former digitizing effect device, also changed the user buy effect device have only several audios and unrenewable history all has outstanding characteristics in economy and practicality.The user just can obtain permanent audio by disposable purchase and upgrade.
3) firmware (DSP algorithm routine) upgrading mode
Here our said firmware is the DSP algorithm routine, and concrete firmware upgrade mode is as follows:
The first, we are divided into two parts with it in the middle of original FLASH chip, and a part is to be used for storing initial DSP algorithm routine and DSP code converter, and another part is used to provide the storage space of customer upgrade DSP program.
The second, by the input of USB interface, the DSP algorithm routine is with automatic decompress(ion) after user's download arrives up-to-date DSP algorithm routine.
The 3rd, but the DSP code converter in the FLASH chip convert new DSP algorithm routine the code of programming to and write in the middle of the FLASH, firmware upgrade is finished.
