Loudspeaker enclosure system having detachable wireless headphones and control method thereof
The present invention discloses a loudspeaker enclosure system having detachable wireless headphones, including: a loudspeaker enclosure and wireless headphones, where the loudspeaker enclosure and the wireless headphones may be used separately; also, the wireless headphones are arranged with a first connector, and the loudspeaker enclosure is arranged with a second connector. The first connector and the second connector may be fit into an electrical plug connection to use the wireless headphones and the loudspeaker enclosure in combination, so that the wireless headphones receive wireless audio signals and output the wireless audio signals to the loudspeaker enclosure to enable the loudspeaker enclosure to play music. The present invention can receive wireless audio signals and play music anywhere with the wireless headphones, and can also share music with others by playing music with the loudspeaker enclosure when necessary.
