Claim Text:
1. A smart hearing amplifier device placed in an ear of a user to receive voices of speakers and connected to a smart device, comprising: a source microphone for receiving the voices of the speakers; a Bluetooth chipset connected to the source microphone, the Bluetooth chipset converting the voices of the speakers from analog signals to digital signals, and then implementing an anti-noise processing to reduce the noise around the source microphone, and further transmitting the digital signals which have been reduced the noise to the smart device or the anti-noise source module; an anti-noise source module connected to the Bluetooth chipset, the anti-noise source module converting the digital signals transmitted by the Bluetooth chipset to analog signals; an amplifier connected to the anti-noise source module, the amplifier receiving and amplifying the analog signals from the anti-noise source module; a speaker connected to the amplifier, the speaker receiving the analog signals amplified by the amplifier and then converting the amplified analog signals to sound signals for the user; a photoplethysmography (PPG) sensor for emitting lights onto the skin of the ear of the user and capturing reflected lights from the skin of the ear and then outputting PPG signals; a gravity-sensor (G sensor) sensing a triaxial gravitational variation of the user and then outputting sensed signals; and a microcontroller unit (MCU) connected with the PPG sensor, the G sensor and the Bluetooth chipset, the MCU controlling the PPG sensor, the MCU processing the PPG signals from the PPG sensor and the sensed signals from G sensor and eliminating noise signals of the PPG signals and the sensed signals, and then calculating bio-data of the user, the bio-data being transmitted to the Bluetooth chipset, the Bluetooth chipset transmitting the bio-data to the smart device.
