Problems solved by technology

Because human body movement will inevitably cause vibration of the ear wall, this vibration will also cause changes in the pressure in the ear canal, which will be collected by the microphone at the same time, thereby interfering with the analysis of the heart rate signal

Embodiment Construction

[0050] 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.

[0051] figure 1 It is a schematic structural diagram of an earphone capable of detecting heart rate in an embodiment of the present invention. Such as figure 1 As shown, the earphone 100 capable of detecting heart rate includes: a subtraction unit 150, a heart rate detection unit 160, an acceleration sensor 130, an adaptive filtering unit 140, a cavity 110 disposed in the earphone, and a microphone 120 installed in the cavity 110;

[0052] Wherein, the position where the mouth of the cavity 110 fits the earphone shell is the position of the earphone shell that fits the auricle of the human ear when the earphone is worn; the earphone shell where the mouth of the cavity 110 fits has an opening, When the earphone is worn, the cavity and...

Abstract

The invention discloses a heart rate detection method applied to an ear phone and the ear phone capable of detecting the heart rate. The heart rate detection method comprises the steps that a cavity is formed in the ear phone, and a microphone is installed in the cavity; an acceleration sensor is further installed inside the ear phone; adaptive filtering processing is conducted on a signal acquired by the acceleration sensor, so that an estimation signal of a signal, generated by body movement of a wearer, in signals acquired by the microphone is obtained; the estimation signal is subtracted from the signals acquired by the microphone, and a signal related to the heart rate is obtained; heart rate detection is conducted according to the signal related to the heart rate. According to the technical scheme, the microphone is arranged in the airtight cavity, interference from external noise is reduced, signal information acquired by the microphone is intensified, the estimation signal is obtained by conducting adaptive filtering on the signal acquired by the acceleration sensor, the estimation signal is subtracted from the signals acquired by the microphone, then heart rate detection is conducted, and therefore the influence of the body movement of the wearer on heart rate detection can be eliminated.

Description

technical field [0001] The invention relates to the technical field of earphones and heart rate detection, in particular to a heart rate detection method applied to earphones and an earphone capable of detecting heart rate. 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 reaso...
