Abstract

The invention discloses electronic equipment which comprises a cover body and a supporting plate, and the cover body and the supporting plate are sequentially arranged in the thickness direction of the cover body. The light-emitting unit and the light-sensing unit are arranged between the cover body and the supporting plate at an interval, and the area, corresponding to the light-emitting unit and the light-sensing unit, on the cover body is a light-transmitting area; the light shielding structure is arranged between the light emitting unit and the light sensing unit, the light shielding structure can deform in the direction close to at least one of the cover body and the supporting plate, and under the condition that the light shielding structure deforms, one side of the light shielding structure abuts against the surface of the cover body, and the other side of the light shielding structure abuts against the surface of the supporting plate. Through the shading structure, light emitted by the light emitting unit can be prevented from irradiating the light sensing unit through scattering to form light crosstalk, interference of crosstalk light is avoided, the light sensing accuracy of the light sensing unit is improved, and the heart rate measurement accuracy is improved.

Description

technical field [0001] The present application belongs to the technical field of terminals, and specifically relates to an electronic device. Background technique [0002] With the development of intelligence, smart wearable products such as smart watches and smart bracelets that integrate heart rate monitoring functions are becoming more and more popular. Most smart wearable watches use photoelectric measurement to monitor heart rate. The built-in heart rate sensor (light-emitting element and photosensitive element) of the smart watch is close to the skin. When irradiated on the skin surface, based on the principle of blood’s absorption of light, the reflected light intensity will change accordingly. The photosensitive element can be a photo detector (Photo Detector, PD), and the heart rate can be analyzed and monitored by measuring the change of reflected light intensity through the photosensitive element. Then get real-time heart rate data. In the process of existing sm...
