<P>PROBLEM TO BE SOLVED: To provide an intelligent secret key apparatus equipped with sounding device. <P>SOLUTION: The intelligent secret key apparatus is equipped with an MCU and sounding apparatus having a sounding device. The sounding apparatus is connected to the MCU directly or through resistance, capacitor, or signal amplifier device. The sounding device can use loudspeaker or buzzer; and the sounding device can include an A/D converter module or sound chip connected to serial input, parallel input, or the MCU bus. The intelligent secret key apparatus presents information which a user inputs, following application request from a remote terminal of a network or host side and using that presentation information occurred from the sounding device is different each time, enhances the security under use of the apparatus, and makes this invention suitable for the use at a public space. While, this invention improves the easiness to use of the intelligent secret key apparatus and improves gentleness to people of the intelligent secret key apparatus, using that the sounding device can realize functions such as safety alarm of the apparatus, read-write presentation, and operation presentation. <P>COPYRIGHT: (C)2008,JPO&INPIT |
