Multi-connection device and multi-connection method

Abstract

The multi-connection method includes following steps: simultaneously establishing a first connection with a right channel unit of a headphone and a second connection with a left channel unit of the headphone during a connection time by a Bluetooth module; processing a first electrical signal transmitted via the first connection or a second electrical signal transmitted via the second connection by a processor; wherein the processor is coupled to the Bluetooth module; wherein the processor adjusts the first electrical signal to generate the second electrical signal.
