The invention relates to an audio setting method of multiple pieces of multimedia playing equipment, used for setting audio voice of a multimedia playing system with video output interfaces includinga television interface and a projector interface. The method comprises the steps as follows: a Bluetooth chip A is prearranged in a television remote control device, a Bluetooth chip B is arranged ina projector remote control device, and a Bluetooth chip C is arranged in the multimedia playing system; the Bluetooth chip C searches the Bluetooth chip A and the Bluetooth chip B within a preset range, the Bluetooth chip C samples signal strength values of the Bluetooth chip A and the Bluetooth chip B separately within a preset time length and records the signal strength values RSSI; a main control module compares the signal strength values RSSI between the Bluetooth chip C and the Bluetooth chip A and the signal strength values RSSI between the Bluetooth chip C and the Bluetooth chip B, to determine equipment with a stronger signal and equipment with a weaker signal; and audio volumes of playing equipment are automatically adjusted according to the sizes of the signal strength values RSSI.
