摘要

A synchronous loudspeaking system comprises a first Bluetooth receiver, a first processor, a first speaker, a second Bluetooth receiver, a second processor and a second speaker. The first Bluetooth receiver receives a first signal. The first processor electrically connects to the first Bluetooth receiver. The first speaker has a first input terminal electrically connected to the first processor, and a first output terminal. The second Bluetooth receiver optionally receives a second signal. The second processor electrically connects to the second Bluetooth receiver. The second speaker has a second input terminal electrically connected to the second processor and optionally connected to the first output terminal, and a second output terminal. The two speakers sound synchronously when the second input terminal and the first output terminal is electrically connected.
