Beschreibung
Zusammenfassung:The invention provides a side pressure type capacitive sensing device, a working method thereof and electronic equipment. The side pressure type capacitive sensing device comprises a circuit board, and a capacitive sensing chip is arranged on the circuit board; moreover, the side wall of the circuit board is provided with a concave part, the bottom wall of the concave part is provided with a firstcapacitance induction piece, and the first capacitance induction piece is electrically connected with the capacitance induction chip. A base body is arranged opposite to the circuit board, a second capacitance induction piece is fixed to the area, right opposite to the concave part, of the base body, the first capacitance induction piece and the second capacitance induction piece are arranged inparallel, and a gap is formed between the first capacitance induction piece and the second capacitance induction piece. The invention further provides a working method of the side pressure type capacitive sensing device. The e
