Embodiment
Below in conjunction with accompanying drawing and preferred embodiments the present invention is described in further detail:
Please refer to Fig. 1, the preferred embodiments of keyboard 10 of the present invention comprises a main body (figure do not show), be arranged at plurality of keys (figure does not show) on the main body, a keyboard scan module 1, an audio-frequency signal coding module 5 and an audio output interface 6.
Said keyboard scan module 1 is used for identification by the key assignments of button (button that promptly is pressed), and it is identical with keyboard scan module in the existing keyboard, can adopt the ranks method of retouching to discern user's input.
Said audio-frequency signal coding module 5 is used for converting key assignments into the corresponding audio coded signal, and it can be the embedded equipment of software and combination of hardware, and it comprises one a key assignments-audio value modular converter 3 and a sound signal generation module 4.Said key assignments-audio value modular converter 3 comprises the coding correspondence table of a key assignments and audio value, and wherein each key assignments is corresponding to an audio value.Said key assignments-audio value modular converter 3 is used for being converted into the corresponding audio value by the key assignments of button.
Said sound signal generation module 4 is used for the pairing audio value of the key assignments by button that obtains is compiled into audio coding signal.Said audio output interface 6 is used to export this audio coding signal.
When keyboard 10 work, the behaviour in service of said keyboard scan module 1 real time monitoring button, when button was pressed, said keyboard scan module 1 was promptly read the key assignments of this button.Said audio-frequency signal coding module 5 identifies behind the key assignments of said keyboard scan module 1; Coding correspondence table through key assignments in said key assignments-audio value modular converter 3 and audio value is found the corresponding audio value; This audio value forms audio coding signal through said sound signal generation module 4 establishments, exports the audio coding signal of these buttons again from said audio output interface 6.
Please refer to Fig. 2; The terminal device 30 that is connected with keyboard 10 of the present invention comprises an audio input interface 26, an audio signal decoding module 25, a KBC 27 and a processor 28, and said terminal device 30 can be the terminal device that mobile phone, computer etc. have COBBAIF.
Said audio input interface 26 is used for linking to each other with the audio output interface 6 of keyboard 10, to receive the audio coding signal from said audio output interface 6.
Said audio signal decoding module 25 comprises an audio identification module 24 and one audio value-key assignments modular converter 23.Said audio identification module 24 is used for identifying the audio value of audio coding signal.Store the coding correspondence table (figure does not show) of an audio value and key assignments in said audio value-key assignments modular converter 23, wherein the corresponding key assignments of each audio value.Said audio value-key assignments modular converter 23 is used for converting audio value to corresponding key assignments.The function of said audio signal decoding module 25 can realize by software, the user can independently install have this function software in the terminal device 30 of compatibility.
Said KBC 27 is according to the input action that identifies said keyboard 10 from the key assignments in the audio signal decoding module 25, and it is transferred to said processor 28, and said processor 28 promptly responds the input action of said keyboard 10.So, said terminal device 30 can through its COBBAIF realize with keyboard 10 between communicate by letter.
Above-mentioned keyboard 10 and terminal device 30 have realized between said keyboard 10 and said terminal device 30, passing through the demand of COBBAIF transmission of data signals through said audio-frequency signal coding module 5 and said audio signal decoding module 25.
