Abstract: The smart hearing amplifier device is placed in an ear of a user to receive voices of speakers. The smart hearing amplifier device includes a Bluetooth chipset, a photoplethysmography (PPG) sensor, a gravity-sensor (G sensor) and a microcontroller unit (MCU). The PPG sensor emits lights onto the skin of the ear and captures reflected lights from the skin and then outputs PPG signals. The G sensor senses a triaxial gravitational variation of the user and then outputs sensed signals. The MCU is connected with the PPG sensor, the G sensor and the Bluetooth chipset. The MCU processes PPG signals from the PPG sensor and the sensed signals from the G sensor and eliminates noise signals of the PPG signals and the sensed signals, and then calculates bio-data of the user. The Bluetooth chipset receives the bio-data from the MCU and transmits the bio-data to a smart device.

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.
