Intelligent key apparatus equipped with sounding device

Abstract

The invention discloses an intelligent key device with a sounding device, which includes an MCU and a sounding device. The sounding device includes a sounding device and is directly connected to the MCU, or connected to the MCU through a resistor, a capacitor or a signal amplifying device. The sounding device can be a speaker or a buzzer, and the sounding device can include a serial input or parallel input or a digital-to-analog conversion module or a voice chip connected to the MCU bus. According to the application requirements of the remote end of the network or the host end of the smart key device, the prompt information sent by the sounding device can be different each time, reminding the user of the information to be input, which increases the security of the device during use, making the present invention more suitable for Use in public. At the same time, the use of the sound device can realize the functions of equipment safety warning, reading and writing prompts, and operation prompts, which improves the usability of the smart key device and makes the smart key device more humanized.

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 ...

Examples

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...
