Implementation system, implementation method, and use method for acoustic keyboard

Abstract

The invention is suitable to be used in the field of input equipment technological improvement, and provides an implementation system for an acoustic keyboard. The system comprises a generating end, areceiving end, a signal processing module, and a display module. The generating end is used to make a keyboard using a bendable flexible material, and an acoustical signal in preset frequency is generated when a key on the keyboard is clicked. The receiving end is used to receive the acoustical signal generated in the generating end, and transmits the acoustical signal. The signal processing module is used to receive the transmitted acoustical signal, and analyzes and processes the received acoustical signal, and determines whether key sound of tapping the keyboard exists, and performs noiseremoval treatment on the received acoustical signal, and determines which key the sound of tapping the keyboard belongs to. The display module is used to display a character corresponding to a tappedkey which is detected according to processing and analysis. A wireless keyboard which can be carried with a person is designed using the flexible material. Using the keyboard, each key can generate amodulated acoustical signal in the preset frequency, so that a mobile device achieves a function of distinguishing tapped key just through sound.

Description

technical field [0001] The invention belongs to the technical improvement field of input devices, and in particular relates to a realization system, realization method and use method of an acoustic keyboard. Background technique [0002] With the popularity of the Internet and the rise of mobile devices, text input on the mobile terminal has become a current and near future development trend. However, the text input on the mobile terminal is not as convenient as that on the PC terminal. Due to the size of the mobile terminal, it is not easy to combine the keyboard with the mobile device. Considering to be easy to carry, our wireless keyboard should be designed with soft material. [0003] The existing mature wireless keyboard input technology is mainly divided into two types: one is to use WiFi as a medium to transmit keystroke information on the keyboard, and the other is more common to use Bluetooth as a communication link between the mobile terminal and the keyboard. te...

AI Technical Summary

Problems solved by technology

Not to mention the high power consumption of WiFi, in terms of portability, most of them are large in size and not easy to carry

The keyboard input method in scientific research also uses machine learning to identify the keystrokes. Using this method does not even need to carry the keyboard, but can freely define the keyboard area, but the disadvantage is also obvious, that is, every time Each defined button needs to be trained before use, and even the position of the mobile terminal will cause retraining
