Description

  The present invention relates to an earphone, and more particularly to an insert earphone with a built-in heart rate monitor.

It is an important need for an exerciser to monitor physiological signals during exercise.
The most important index in the physiological signal and the highest reference value is the heart rate.
Therefore, the heart rate signal monitor is a typical function of current wearable physiological signal measurement devices.

Many of the wearable physiological signal measurement devices mainly measure electric signals. However, the electric signal measurement devices have a complicated structure, are complicated to wear, and cannot support the user's detection at any time.
A wearable physiological signal measurement device mainly using optical signal measurement can solve the above problems.
Many of wearable physiological signal measuring devices that mainly measure optical signals are insert earphones with a built-in heart rate monitor. By combining optical sensors and earphones, not only music can be heard but also heart rate signals can be monitored.
Many of the earphones for measuring electrical signals currently measure the structure of the outer ear, and the optical sensor is located at the lower edge of the ear, so that the measurement signal is only the skin surface layer.

Since the skin at the position of the outer ear of the human body is thin and the external environment light source is likely to be transparent, the optical signal is likely to be interfered with by the environment light source, and the measurement is likely to be inaccurate.
Therefore, it is awaited to devise a new earphone that is rational and effectively solves the above problems.
