An automatic wire arranging device includes a controller, at least one driving device electrically connected with the controller, a wire clamping jig, a wire arranging rotor, at least one charge-coupled device camera and a puncher pin. The wire clamping jig is connected with the at least one driving device. The wire arranging rotor has a spindle, and a cylinder-shaped base portion fastened to a tail end of the spindle. An outer side surface of the base portion is equipped with a plurality of clamping portions. The plurality of the clamping portions are used for clamping a plurality of different characteristic core wires. The wire arranging rotor is connected with the at least one driving device. The at least one charge-coupled device camera faces towards the wire clamping jig and is connected with the controller. The puncher pin is movably disposed above the wire clamping jig.

An earbud charging storage case for storing and charging a pair of earbuds, includes an earbud holder, and a magnetic component bracket looped around the earbud holder. Each earbud has a magnetic element. The earbud holder has a base portion. Two sides of a bottom surface of the base portion protrude downward to form two accommodating portions. Two sides of a top surface of the base portion are recessed downward to form two lower receiving grooves. The two accommodating portions have two accommodating grooves. The two lower receiving grooves and the two accommodating grooves together define two storing grooves. The pair of the earbuds are accommodated in the two storing grooves. Several portions of a bottom surface of the magnetic component bracket are recessed upward to form a plurality of buckling grooves. Each of the plurality of the buckling grooves is equipped with a first magnetic component.

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.
