The internal analysis control system that member 3, analysis and processing unit 4 and control unit 5 are constituted is judged to speaker and password, this
When correct (high level) password of speaker it is correct (high level), safety verification passes through (high level).It is wrong in speaker's proper password
Situation, such as Fig. 4 (b) shown by mistake, now correct (high level) code error (low level) of speaker, and safety verification does not pass through
(low level)；In the correct situation of speaker's bad password, shown in such as Fig. 4 (c), human factor error (low level) password is now being spoken just
Really (high level), safety verification does not pass through (low level)；In the present embodiment, high level is represented and is identified by, and low level, which is represented, to be known
Do not pass through.
This self-driven vocal print sensor that embodiment is provided, and the Application on Voiceprint Recognition based on the self-driven vocal print sensor
Security system, by collecting the acoustic pressure that sound is produced on vocal print sensor, is converted to electric energy by the mechanical energy of acoustic pressure, realizes sound
The self-driven function of line sensor；Because vocal print sensor uses porous polymer polymeric material, with high sensitivity,
Provided safeguard for accurate vocal print sensing with identification；And on the other hand, the self-driven vocal print sensor is rollable, fold processing,
Can under any bending, any angle works fine, deft design, make relatively simple, performance is stable, with low cost, be adapted to
Large-scale industrial production.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not used to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention etc., it all should include
Within protection scope of the present invention.
