Abstract
The utility model discloses a full-wireless split-type stereo active sound box, and the sound box consists of a main sound box and an auxiliary sound box. The sound box is characterized in that the main sound box consists of a Bluetooth audio receiving module, an audio decoding chip, a wireless audio transmitting module, a power amplifier, a loudspeaker, a 12V lithium battery power supply, a USB interface, an SC card interface, a line in input interface, and a box body; the audio decoding chip not only supports lossless audio formats, including FLAC, APE, and the like, but also supports lossy audio formats, including AAC, OGG, and the like. The decoded audio frequency is divided into two sound channels, wherein one sound channel (left or right sound channel) is used for connecting the power amplifier of the main sound box. After the amplification through the power amplifier, the loudspeaker is directly pushed to make a sound. The other sound channel (right or left sound channel) is used for audio wireless transmission for the auxiliary sound box through the wireless audio transmitting module. The transmission technology employed by the wireless audio transmitting module is one of the Bluetooth technology (bluetooth), the technology of 2.4G wireless transmission, and the technology of WIFI (WLAN).
