萨克斯 is a phonetic transliteration of 'sax' (after Belgian inventor Adolphe Sax, 1814-1894), and 管 ('pipe/tube') marks it as a wind instrument. In casual speech, people often shorten it to just 萨克斯.

The instrument was invented around 1840 by Adolphe Sax - Chinese keeps his name (萨克斯) and adds 管 to classify it as a tube-shaped wind instrument, the same way 长笛 'flute' uses 笛 (flute).
