Description

technical field [0001] The invention relates to the field of wireless audio equipment, in particular to an easy-to-use wireless music system for square dancing. Background technique [0002] Square dancing has brought fitness benefits and spiritual enjoyment to people. Small squares near residential areas with high crowd density are often used as sports venues for "fitness-type" square dancing. Residents in the community have a high degree of participation and have a great impact on the surrounding environment. However, the traditional square dance music rhythm mainly uses high-power speakers as the sound source. This kind of speakers is not only bulky and difficult to build, but also in order to meet the needs of each dancer, the organizer must output dance music in a high-decibel manner. Therefore, it has brought serious noise disturbance to surrounding residents, and social conflicts and conflicts caused by this often occur. [0003] Chinese utility model patent CN203352...
