Abstract
The present disclosure provides a headset charging and data transmission system, which includes a headset and a charging device. The charging device includes a first controller, a first connector, a first switching device, and a second switching device. The first switching device is electrically connected to the first controller and the first connector, and the second switching device is electrically connected to the first controller and the first switching device. The first controller controls the second switching device to switch between the first and second voltages to provide a first data signal for the first switching device, so that the first data signal is output to the headphones via the first connector.
Claims10
A headset charging and data transmission system, comprising:
- a headset;
- and
- a charging device comprising:
- a first controller;
- a first connector configured to connect the headset;
- a first switching device electrically connected to the first controller and the first connector, the first switching device having a first sending terminal, a first receiving terminal, a power supply terminal and a first transmission terminal, the first transmission terminal electrically connected to the first connector, the first transmission terminal electrically connected to one of the first sending terminal, the first receiving terminal and the power supply terminal selectively;
- and
- a second switching device electrically connected to the first controller and the first switching device, the second switching device having a first voltage input terminal, a second voltage input terminal and a first output terminal, the first output terminal electrically connected to the first sending terminal, the first voltage input terminal configured to receive a first voltage, the second voltage input terminal configured to receive a second voltage, the first controller based on first data to control the second switching device to electrically connect the first output terminal to the first voltage input terminal or the second voltage input terminal alternately, so that the first output terminal provides a signal of the first data for the first sending terminal, and the first controller configured to control the first switching device to electrically connect the first sending terminal to the first transmission terminal, so that the first connector outputs the signal of the first data to the headset,
- wherein the first controller controls the first switching device to electrically connect the first receiving terminal to the first transmission terminal, so that the first receiving terminal receives a signal of second data that is sent from the headset to the first connector, and before the headset prepares to send the signal of the second data, the headset sends a second interruption signal.
