Calculating machine

Abstract

The invention discloses a calculating machine. The calculating machine comprises an input module, a calculating module, a display module, a microphone, a recognition module and a reminding module, wherein the input module is used for receiving the input operation of a user through buttons and generating corresponding input signals; the calculating module is used for receiving the input signals and calculating; the display module is used for displaying calculating results of the calculating module; the microphone is used for collecting sound information; the recognition module is used for detecting whether the input module generates input signals or not when the extent of the sound information reaches to a preset threshold value; and the reminding module is used for emitting reminding information when the sound information recognized by the recognition module reaches to the preset threshold value and the input module does not generate input signals. According to the calculating machine disclosed by the invention, the situation of unsuccessful input can be found in time through the sound of the buttons and the existence of the input signals, and the user can be reminded.

Description

technical field [0001] The invention relates to a calculator, in particular to a calculator with keys. Background technique [0002] Calculator (counter) generally refers to "electronic calculator", which was introduced into China from Japanese. A calculator is a hand-held machine that can perform mathematical operations. It has an integrated circuit chip, but its structure is simple, much simpler than that of modern computers. It can be said to be the first generation of electronic computers (computers), and its functions are weak, but it is more convenient and It is cheap and can be widely used in commercial transactions. It is one of the necessary office supplies. [0003] Calculator, a small program machine, is actually a derivative of the computer, but because of its convenient and fast operation mode, it has been widely used in engineering, learning, business and other daily life, which is very convenient People's integration of numbers. [0004] In the process of u...

Problems solved by technology

[0004] In the process of using a calculator, people sometimes fail to input because of the insensitivity of the key itself or the inaccurate pressing position.

However, when people input information such as numbers, it is usually faster, and it is difficult to find that the input is unsuccessful, resulting in an error in the final calculation structure
