Description

technical field [0001] The invention relates to an audio device, in particular to a ceiling-mounted audio device based on beam control. Background technique [0002] With the rapid development of VLSI and battery storage technologies, portable consumer audio products—handheld computers, smart phones, digital cameras, e-book readers, personal audio and video players, etc. It provides great convenience for working and living. These audio products usually have wireless interfaces such as NFC, Bluetooth, and Wi-Fi, which can quickly and flexibly establish wireless connections and exchange data with other audio products with the same wireless interface. Based on these wireless interface technologies, wireless audio products based on Bluetooth or Wi-Fi have also appeared on the market. These audio products are usually used as external accessories for smart phones to provide external sound field playback for smart phones. These wireless audio products are usually equipped with tw...
