Electronic device

Abstract

The invention discloses electronic equipment. The electronic equipment comprises a frame body; the circuit board is arranged on the frame body; the key is movably arranged on the frame body, a first conductive part and a second conductive part are arranged on the key, and the first conductive part and the second conductive part are insulated from each other; one end of the first vibrating needle is electrically connected with the first area of the circuit board; one end of the second vibrating needle is connected with the second area of the circuit board; when the key is in a first state, the other end of the first vibrating needle is electrically connected with the first conductive part, and the other end of the second vibrating needle is electrically connected with the second conductive part; and when the key is in the second state, the other end of the first vibrating needle and the other end of the second vibrating needle are electrically connected with the second conductive part, and when the key is in the first state and the second state, the levels of the second vibrating needle are different. The use state of the key can be judged through the level of the second elastic needle, different responses can be made according to the state of the key, metal fatigue of the metal elastic sheet can be avoided, and the performance of the ECG is guaranteed.

Description

technical field [0001] The present application belongs to the technical field of terminals, and specifically relates to an electronic device. Background technique [0002] At present, common smart bracelets / watches only have the measurement function of heart rate and blood oxygen, but the heart rate and blood oxygen measurement functions cannot directly feed back the health of the heart, while the electrocardiogram (hereinafter referred to as ECG) detects the extreme Therefore, the demand for watches with ECG measurement function is increasing day by day. [0003] For a single-lead ECG, the measurement process requires three dry electrodes to take the potential difference of two parts, and the potential difference of the arms and legs can be taken. In wearable devices, the potential of different parts can be detected through electrodes, and ECG measurement can be realized according to the potential difference between two parts. The current design scheme realizes the electr...
