Embodiment Construction

[0036] The present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] The sound generating device in the present invention can adopt various forms, and can be various sounds, such as: voice prompt, music or ringtone, etc., and the sound generating device can be selected from a loudspeaker or a buzzer.

[0038] When using a voice chip, if the voice content does not need to be modified after writing, you can consider using OTP type (one-time programming) voice circuit and mask type voice circuit; if the voice content needs to be modified frequently, you should use ISD series or APR series Voice recording and playback circuit. The voice chip and the microcontroller communicate through a serial communication interface (SPI or Microwire).

[0039] When the buzzer is used, the buzzer is divided into two types: piezoelectric and electromagnetic, which can be selected according to different needs. The buz...

Abstract

The invention relates to an intelligent key device with sound device. Wherein, it comprises MCU and sound device; the sound device comprises sound element connected to the MCU directly or via resistance, capacitor, or signal amplifier; the sound element can be loudspeaker or buzzer; the sound element can comprises an A / D converter or sound chip with serial input or parallel input that connected to the MCU bus. The invention based on the need of remote terminal or host uses sound element to generate prompt information, which can be different each time, to prompt input information, to improve the safety. And the sound element can realize safety alarm, read-write prompt, and operation prompt, etc.

Description

technical field [0001] The invention relates to the field of information security, in particular to an intelligent key device. Background technique [0002] At present, the division of technical fields is becoming more and more detailed, and the research and development of various fields are getting more and more in-depth. People in different fields have little knowledge of technical knowledge in other fields, and even feel very strange and mysterious about products in other fields. In the process of operation and use, people require that various equipment not only have powerful functions to meet their requirements, but also be simple and easy to use. At the same time, people have higher and higher requirements for humanization in the use of various equipment. Type equipment is more favored by consumers in the market. [0003] As the most important means of human communication, sound and images are also reflected in the design of electronic products. Using a voice chip to ...
