Remote controller with dual power supply units
A remote controller with dual power supply units is provided. The remote controller controls an electronic apparatus. The remote controller includes a housing, a first sub-system and a second sub-system. The first sub-system is disposed in the housing and includes a first power supply unit for powering the first sub-system. The first sub-system further generates a first signal for controlling the electronic apparatus to perform a first operation. The second sub-system is disposed in the housing and includes a second power supply unit for powering the second sub-system. The second sub-system further generates a second signal for controlling the electronic apparatus to perform a second operation.
1. A remote controller, for controlling a television, the remote controller comprising:
a housing;
a first sub-system, disposed in the housing, comprising:
a first power supply, for powering the first sub-system;
a button module, coupled to the first power supply, comprising a plurality of operation buttons, for generating a first signal for controlling the television to perform a first operation corresponding to one of the operation buttons being pressed; and
an infrared transmitter, for transmitting the first signal to the television,
wherein said first power supply generates power to the first sub-system only when a button of the button module is pressed; and
a second sub-system, disposed in the housing, comprising a second power supply for supplying power continuously to the second sub-system, the second power supply comprising a rechargeable power device, the second sub-system generating a second signal for controlling the television to perform a second operation,
wherein the second power supply is coupled to the first sub-system, and powers the first sub-system when a button of the button module is pressed and a power of the first power supply is lower than a predetermined value,
wherein when the remote controller is not in use, the second power supply is connected to a charging transformer.
2. The remote controller according to claim 1 , wherein the second sub-system comprises:
an acoustic control module, coupled to the second power supply, comprising a microphone for converting an acoustic signal to the corresponding second signal; and
a transmitter, for transmitting the second signal to the television.
3. The remote controller according to claim 1 , wherein the second sub-system comprises:
a touch control module, coupled to the second power supply, comprising a touch panel, for converting a touch control signal to the corresponding second signal; and
a transmitter, for transmitting the second signal to the television.
4. The remote controller according to claim 1 , wherein the second sub-system comprises:
a sensor module, coupled to the second power supply, comprising a gravity sensor, for converting a sensor signal to the corresponding second signal; and
a transmitter, for transmitting the second signal to the television.
