Patent number: 9833156Abstract: 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.Type: GrantFiled: February 6, 2012Date of Patent: December 5, 2017Assignee: Beijing Choice Electronic Technology Co., Ltd.Inventors: Shuhai Liu, Feng Xu, Yanqing Zhang
