An electrical connection assembly is provided to electrically connect with at least one electrical contact of an electronic apparatus. The electrical connection assembly includes an insulating casing, a circuit board and a resilient conductive element. An inner space is defined in the insulating casing, and at least one opening is defined on the insulating casing for communicating the inner space and the exterior of the insulating casing. The circuit board is disposed in the inner space of the insulating casing. The resilient conductive element includes a connecting side for fixing on and electrically connecting with the circuit board. The resilient conductive element further includes a compressible side for facing the opening and being exposed therethrough. The thickness of the resilient conductive element is reduced when an external force is applied thereon and recovers when the external force is removed.

Electrical connection assembly, battery device and electronic apparatus

In an amplifying circuit, an amplifier receives an input signal via a first resistor unit, and generates an output signal at an output thereof. A second resistor unit is connected between the output and input of the amplifier, and has at least one control input. The second resistor unit has a variable equivalent impedance that is controlled by a control signal received at the control input. A feedback control unit receives the output signal from the amplifier, and is operable so as to provide the control signal to the control input of the second resistor unit when the output signal does not fall within a voltage range defined by a predetermined low voltage and a predetermined high voltage to adjust the variable equivalent impedance of the second resistor unit.
