Heart rate detection apparatus
First Claim
1. A heart rate detection apparatus, comprising:
- a signal acquisition device for acquiring an intra-aural vibration wave signal and converting the intra-aural vibration wave signal into an intra-aural vibration electrical signal, wherein the intra-aural vibration wave signal comprises vibration wave signals caused by blood flowing inside an ear and conducted into an ear canal of the ear by a tympanic membrane and vibration wave signals conducted into the ear canal by bones and/or tissues that are cartilage inside the ear and by bones and/or tissues that are not cartilage inside the ear; and
an arithmetic processing device for processing the intra-aural vibration electrical signal by computing to generate heart rate information,wherein the signal acquisition device comprises a signal acquisition unit and a front-end signal processing unit,wherein the signal acquisition unit is used foracquiring the intra-aural vibration wave signal,converting the intra-aural vibration wave signal into the intra-aural vibration electrical signal,outputting the intra-aural vibration electrical signal to the front-end signal processing unit,acquiring a vibration wave signal outside the ear, which comprises a vibration wave signal produced by a vessel in an auricle of the ear,converting the vibration wave signal outside the ear into a vibration electrical signal outside the ear, andoutputting the vibration electrical signal outside the ear to the front-end signal processing unit, andwherein the front-end signal processing unit is used forfiltering and amplifying the intra-aural vibration electrical signal,outputting the filtered and amplified intra-aural vibration electrical signal to the arithmetic processing device,performing a compensating and feedback process to the intra-aural vibration electrical signal based on the vibration electrical signal outside the ear, andoutputting the intra-aural vibration electrical signal subjected to the compensating and feedback process to the arithmetic processing device.

Abstract
A heart rate detection apparatus includes a signal acquisition device for acquiring an intra-aural vibration wave signal and converting the intra-aural vibration wave signal into an intra-aural vibration electrical signal; and an arithmetic processing device for processing the intra-aural vibration electrical signal by computing to generate heart rate information. In the prior art, the heart rate detection apparatus cannot accurately and reliably detect the heart rate information due to the weak optical signal detected by a sensor. The heart rate detection apparatus acquires the intra-aural vibration wave signal to obtain the heart rate information, thus enabling the apparatus to accurately and reliably detect heart rate information.
