Abstract

The invention provides a pressure detection circuit, electronic equipment and a control method of the pressure detection circuit. The pressure detection circuit comprises at least one first detectionunit which is used for sensing an acting force in a first direction, at least one second detection unit which is used for sensing the acting force in the second direction, and a pressure detection chip, wherein the first detection unit and the second detection unit have different induction parameters corresponding to different acting forces; the first direction and the second direction form a preset angle; the pressure detection chip is connected with the first detection unit and the second detection unit; and the pressure detection chip determines a first pressure parameter in the first direction and a second pressure parameter in the second direction according to the induction parameter of the first detection unit and the induction parameter of the second detection unit, and determines whether to output a trigger instruction or not according to the first pressure parameter and the second pressure parameter. According to the invention, pressure detection in two directions can be realized to determine whether to output the trigger instruction, and false triggering is avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a pressure detection circuit, electronic equipment and a control method for the pressure detection circuit. Background technique [0002] At present, the appearance of electronic devices such as mobile phones and tablets is developing towards simplicity and integration. Traditional physical buttons need to have holes, which damage the integrity of the appearance, and are gradually being replaced by hidden buttons. The hidden button realizes the button function, avoids openings in the appearance, and is conducive to waterproof design, reducing the risk of ESD (Electro-Static Discharge, electrostatic discharge). [0003] However, the hidden button in the related art still transmits the pressure trigger command under the action of bending, torsion and other forces, and there are serious accidental touches, which affects the user experience. Contents of the invention [0004] ...
