Pressure-sensing module and electronic device

An electronic device, comprising:

• a pressure-sensing module, a screen display module, and a pressure-sensing control unit, wherein the pressure-sensing module is provided under the screen display module;
• the pressure-sensing module comprises;
• a circuit board, wherein the circuit board has a first surface and a second surface disposed opposite each other and parallel to each other;
• multiple elastic members, wherein the multiple elastic members are electrically connected to the circuit board, and the multiple elastic members comprise a first elastic member, a second elastic member, a third elastic member, and a fourth elastic member;
• and
• multiple piezoresistors comprising a first piezoresistor, a second piezoresistor, a third piezoresistor, and a fourth piezoresistor, wherein
• the first piezoresistor is located on the first surface, two terminals of the first piezoresistor are respectively connected to the first elastic member and the second elastic member;
• the third piezoresistor is located on the second surface, one terminal of the third piezoresistor is connected to the first elastic member and another terminal is connected to the second elastic member or the fourth elastic member;
• and the first piezoresistor and the third piezoresistor are electrically connected and form a first channel;
• the second piezoresistor is located on the first surface, two terminals of the second piezoresistor are respectively connected to the third elastic member and the fourth elastic member;
• the fourth piezoresistor is located on the second surface, one terminal of the fourth piezoresistor is connected to the third elastic member and another terminal is connected to the fourth elastic member or the second elastic member;
• and the second piezoresistor and the fourth piezoresistor are electrically connected and form a second channel;
• and
• the first channel intersects or connects with the second channel to form a bridge circuit, wherein the bridge circuit is configured to detect a pressure value based on an electrical parameter difference between the first channel and the second channel.
