Intelligent equipment key control device and method thereof

Abstract

The invention provides an intelligent equipment key control device. The device comprises a shell, a processing module and one or more piezoelectric sensors, wherein the shell is arranged on the outersurface of the intelligent device and is used for coating the intelligent device; the piezoelectric sensor is arranged on the inner side of the shell and is used for acquiring an elastic wave signal generated by touching the outer surface of the shell and converting the elastic wave signal into a voltage signal; the processing module is connected with the piezoelectric sensor and is used for calculating touch data generated by touch of the outer surface of the shell according to the voltage signals acquired by the piezoelectric sensor; and the touch data is compared with a preset threshold value, and a pre-stored control signal corresponding to the touch data is output according to a comparison result.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a key control device and method for an intelligent device. Background technique [0002] Although most of the operations of electronic devices such as portable phones and tablet computers currently on the market are completed through touch screens, traditional mechanical switches or volume keys and other pressing components cannot be discarded. The volume problem leads to an increase in the overall thickness and weight of the electronic device. For this reason, the thinning and thinning of electronic equipment has become an important indicator of whether the electronic equipment is beautiful and whether its scientific and technological performance is high. At the same time, the use of mechanical switching elements for sensing also leads to the inability of the electronic equipment to achieve complete waterproof or dustproof effects at these mechanical elements; at the same tim...

Problems solved by technology

At the same time, the use of mechanical switching elements for sensing also leads to the inability of the electronic equipment to achieve complete waterproof or dustproof effects at these mechanical elements; at the same time, when the mechanical elements are in use, the wear and tear of the body itself has become a factor that affects the life of the electronic equipment. a major factor

[0003] Taking mobile phones as an example, with the development of science and technology, technologies such as touch screens have become more mature, existing mobile phones have gradually abandoned the physical keypads of previous mobile phones, so as to make mobile phones more reasonable and portable in terms of size and weight; However, some physical buttons of existing mobile phones still exist, such as volume, screen switches and other pressing components; these physical buttons or physical buttons lead to the need to leave space on both sides or upper and lower sides of the phone body when designing the body structure. This is a waste of money in a place like a mobile phone, and it also causes light leakage in the mobile phone; for this reason, the industry urgently needs a new control method to replace the existing smart device button control structure and method
