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, the speed is usually faster, and it is difficult to find that the input is unsuccessful.

Embodiment Construction

[0013] Such as figure 1 As shown, it is a functional block diagram of a calculator 10 in a preferred embodiment of the present invention.

[0014] A calculator 10 includes an input module 001 , a calculation module 002 , a display module 003 , a microphone 004 , an identification module 005 and a reminder module 006 .

[0015] The input module 001 receives user input operations through keys and generates corresponding input signals.

[0016] The calculation module 002 is used for receiving the input signal and performing calculation.

[0017] The display module 003 is used to display the calculation result of the calculation module 002.

[0018] The microphone 004 is used to collect sound information.

[0019] The recognition module 005 is used for detecting whether the input module 001 generates an input signal when the amplitude of the sound information reaches a preset threshold.

[0020] The reminder module 006 is configured to send a reminder message when the recognit...

Abstract

A calculator, include an input module, Calculation Module and Display Module, the input module is used for receiving user input operation by pressing a key, generating a corresponding input signal, the computing module is configured to receive the input signal, Perform calculations, the display module is used for displaying the calculation result of the calculation module, The calculator further comprises: a microphone, an identification module and a reminder module, the microphone is used for collecting sound information, The recognition module is configured to detect whether the input modulegenerates an input signal when the amplitude of the sound information reaches a preset threshold value, and the reminder module is configured to send a reminder message when the recognition module recognizes that the sound information reaches a preset threshold value and the input module does not generate an input signal. The calculator of the invention can timely find out the unsuccessful inputsituation through the presence or absence of the key-press sound and the input signal, and reminds the user that it is convenient to use.

Description

technical field [0001] The invention relates to a calculator, in particular to a calculator with keys. Background technique [0002] Calculator generally refers to "electronic calculator", which was introduced into China from Japanese. Calculator is a hand-held machine that can perform mathematical calculations. It has an integrated circuit chip, but its structure is simple, much simpler than that of modern computers, and its functions are weaker, but it is more convenient and cheap, and can be widely used in commercial transactions. It is a must One of the best 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 using a calculator, people sometimes fail to input because of the insensitivity of the key ...
