Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] In the existing heart rate detection technology of earphones, the microphone is usually placed directly in the earphone at the position facing the ear canal to collect the pressure change information in the ear cavity caused by the vibration of the eardrum. The matching effect is not necessarily very tight, and the airtightness of the space surrounded by the earphone shell and the ear canal wall is not ideal, so the pressure change information collected by the microphone in this space is relatively weak, and it is difficult to detect the heart rate; and because the earphone shell The airtightness of the space surrounded by the ear canal wall is poor, so that the microphone located in this space will also be interfered by external...

Abstract

The invention discloses an earphone and a heart rate detection method. The earphone comprises an earphone shell; the earphone shell is provided with an opening; the earphone shell is internally provided with a closed case; the closed case is internally equipped with a microphone; a contact surface is arranged on the surface of the closed case; the contact surface is installed at the opening; and when the earphone is worn, the contact surface is in contact with an external ear of a human ear. The heart rate detection method comprises the following steps: when the earphone is worn, collecting a signal generated by pressure changes in the closed case by the microphone; and performing heart rate detection according to the signal collected by the microphone. According to the earphone and the heart rate detection method provided by the invention, by setting the closed case inside the earphone shell and installing the microphone in the closed case, even if the contact surface of the earphone is not completely in contact with the external ear, the closed case can still well convert skin vibration into vibration of gases in the closed case, so that the microphone can still collect strong enough heart rate signals.

Description

technical field [0001] The invention relates to the technical field of earphones and heart rate detection, in particular to an earphone and a heart rate detection method. Background technique [0002] With the continuous development of social economy, people's material living standards are improving day by day, and people are paying more and more attention to their health. Heart rate detection will provide people with very important information about health. Any display that is different from the normal heart rate indicates that there is a problem with health. Through heart rate detection, we can find out whether there is a problem with our body in time. Heart rate detection can also reflect whether people's exercise intensity is appropriate to a certain extent. In order to get the best exercise effect, people should keep their heart rate within a certain range during exercise, and heart rate detection can provide a reasonable amount of exercise. an indicator. [0003] In...
