Abstract
A Bluetooth audio broadcasting system includes: an audio broadcasting device arranged to operably broadcast BLE (Bluetooth Low Energy) audio packets; a first Bluetooth member device arranged to operably parse the BLE audio packets to acquire a predetermined audio data and to operably control a first audio playback circuit to playback the predetermined audio data; and a second Bluetooth member device arranged to operably parse the BLE audio packets to acquire the predetermined audio data and to operably control a second audio playback circuit to playback the predetermined audio data. When the first or second Bluetooth member device receives an alert signal, or when a specific ambient sound occurs in the surrounding environment of the first or second Bluetooth member device, the audio broadcasting device utilizes a target control command to instruct the first and second Bluetooth member devices to synchronously reduce their volume to be lower than a predetermined threshold.
