Abstract
A heart rate detection earphone is worn on an auricle which has a cavitas conchae. The heart rate detection earphone includes an earphone body matched with and buckled in the auricle, a light guiding module disposed to the earphone body, and an optical sensor. The light guiding module defines a sensing surface exposed out of the earphone body, and the sensing surface abuts against the cavitas conchae. The optical sensor includes a light emitter and a light receiver respectively coupled with the light guiding module. Light beams emitted by the light emitter are guided by the light guiding module to irradiate the cavitas conchae. The light beams emitted by the light emitter are reflected by the cavitas conchae, and then the reflected light beams reflected by the cavitas conchae are returned to and are received by the light receiver through the light guiding module.
