Abstract

The utility model discloses a computer keyboard with a phonetic device. The phonetic device is composed of a power circuit, a decoding circuit, a phonetic storage circuit, a control circuit for recording and reproducing phonetic signals, etc. The utility model can send out pronunciation corresponding to the keys for an operator for the input and the checking and improving the speed and correctness of data input. The computer keyboard is provided with two operating modes of an online mode and an off line mode.

Description

Speech-sounds keyboard for computer

The utility model relates to and a kind of the fragmented information project is converted into the device of code form, particularly a kind of computer keyboard.

When the active computer keyboard carries out the data input, press the wrong button the position situation happen occasionally, for not with the computing machine of voice system, the operator must often check indicator screen, whether the input of just knowing oneself is wrong, this not only influences input speed, and has influence on the accuracy of data input.

Existing computer input with voice suggestion effect (for example using sound card) is to utilize the intervention of main frame to realize its phonetic function, and will take the resource such as port address, CPU time, internal memory, bus of main frame in addition.

The purpose of this utility model is the deficiency that overcomes the active computer keyboard, provides a kind of can realize whenever just to be sent the computer speech keyboard of this key pronunciation by keyboard by next key.

The function of the utility model computer speech keyboard is achieved in that on the basis of active computer keyboard, add that voice device partly constitutes, this voice device is by power circuit, decoding scheme, the voice memory circuit, recording playback sound control system circuit is formed, the DATA signal wire that computer keyboard is sent is also received the signal input part of voice device part, when certain key is pressed, spread out of this key bit serial sign indicating number on the DATA line, decoding scheme is deciphered it, finds out appropriate address, the record playback control circuit according to appropriate address to the addressing of voice memory circuit, therefrom take out speech data,, become voice signal through the D/A conversion, sound by loudspeaker again, just the pronunciation of this key.Because its self-powered circuit, this computer speech keyboard can not rely on main frame fully and works alone, and has two kinds of method of works:

1: on-line mode: the computer speech keyboard is plugged on the computer keyboard socket of main frame, is used for the computer data typing, on one side operating personnel can be imported, Yi Bian the voice that send according to computer keyboard are proofreaded;

2: off-line mode computer speech keyboard does not connect main frame, is used for the computer keyboard operation training.

The utility model computer speech keyboard does not take any system resource of computing machine, and computer run is not produced any adverse effect, helps improving the speed and the accuracy of data input.Particularly have offline function, become a kind of voice teaching aid of computer keyboard operation training.

Fig. 1 is the profile synoptic diagram of computer speech keyboard.

Fig. 2 is a kind of circuit theory diagrams of realizing of computer speech keyboard.

Fig. 3 is the power circuit principle figure of computer speech keyboard.

With reference to the accompanying drawings embodiment of the present utility model is done concrete the introduction:

As shown in Figure 1, the front side end of computer speech keyboard 1 is equipped with the cable plug 2 that can be connected on the main frame, power lead 3 also is housed on the computer speech keyboard 1, when throwing off being connected of cable plug 2 and main frame, can be from the power supply that power lead 3 is introduced for 1 use of computer speech keyboard.Right flank at computer speech keyboard 1 is provided with the potentiometer W of volume knob 4(corresponding to Fig. 2), be used for regulating the size of volume, earphone socket 5(is corresponding to the SK of Fig. 2) selection of speaker/listening mode is provided.The top of computer speech keyboard 1 is provided with battery case 6 and the switch 7(K4 corresponding to Fig. 3), provide the battery that uses in the battery case 6 or the selection of the external power source introduced from power lead 3 by switch 7.Switch 8(is corresponding to the K1 of Fig. 2) select original voice/autogamy pronunciation, the speech data of original pronunciation is solidificated among the EPROM27512.When switch 8 had been selected the autogamy pronunciation, switch 9(was corresponding to the K2 of Fig. 2) effect be to select recording/playback.When switch 9 was selected recording, the operator whenever clicked the K3 of button 10(corresponding to Fig. 2), followed by the pronunciation of reading out a key facing to microphone (MIC of Fig. 2), the computer speech keyboard just becomes speech data to the voice of this key, is stored among the RAM62512.When switch 9 had been selected playback and switch 8 in autogamy pronunciation position, the operator whenever pressed a key of computer keyboard, and the loudspeaker of computer speech keyboard (SP of Fig. 2) just send the corresponding pronunciation of operator from record.

In computer speech keyboard 1 housing, sound circuit, power circuit and loudspeaker etc. are housed.As shown in Figure 2, the keyboard data pulse signal KBDDATA and the clock signal KBCLK of inner single-chip microcomputer of computer keyboard and main frame communication and receive P10, the P11 pin of decoding scheme U1, U1 selects MC8748 for use.When different keys is pressed or unclamps, the KBDDATA line transmits the different pieces of information signal, by U1 to the KBDDATA signal interpretation, press data corresponding to different keys, producing corresponding 8 bit address signals is sent by bus mouth DB0～DB7 of U1, be sent to the voice memory circuit, the P22 pin by U1 sends the PLAY signal to the record playback control circuit simultaneously.And unclamp data for key, then do not send out the PLAY signal.The voice memory circuit is made up of U2, U3, has solidified each key speech data among the U2, and that select for use in this example is EPROM27512, and U3 is used for from record, and this example is selected RAM62512 for use.According to the position of K1, determine U2 or U3 work by P20, the P21 of U1.The record playback control circuit is by U4(YYH402), LM386, loudspeaker and microphone etc. form, when playback, after U4 receives the PLAY signal, from U2 or U3, read in the speech data information of determining first address by U1, byte-by-byte again speech data information is changed by D/A, be transformed into voice signal, and carry out filtering, amplification and output, send corresponding voice by loudspeaker at last; When radio reception, after U4 receives the PEC signal that the P22 human hair combing waste of U1 goes out, U4 from the voice signal that produces by microphone of MICI pin input by the A/D conversion, be transformed into speech data information, deposit among the RAM62512 and determine in one section storage unit of first address by U1.

Power circuit as shown in Figure 3, K4 be used for selecting be by electric battery B power supply or by by generations+5V power supplys such as transformer BY, rectifier bridge heap ZL, integrated stable voltage circuit 7805, capacitors for sound circuit and keyboard use.PC represents the main frame keyboard socket among Fig. 2, Fig. 3.
