In smart mirrors like those from Artforma , the speakers are mounted directly to the back of the mirror. The glass acts as a protective barrier while the BL12A3 drives the audio through.
The module delivers a stereo output of 3W × 2 with less than 1% total harmonic distortion (THD) and a signal‑to‑noise ratio exceeding 90 dB. In practical terms, this means clean, full‑range sound for spoken word (podcasts, news) and background music, though it is not intended for high‑power home theater use. bl12a3 bluetooth full
A small footprint makes it perfect for a tidy desk. In smart mirrors like those from Artforma ,
The BL12A3 supports both SCO (Synchronous Connection Oriented) links for voice and ACL (Asynchronous Connectionless) links for data, making it a true full-duplex solution. In practical terms, this means clean, full‑range sound
