DHS is a harmonica brand trademark produced by Jiangsu Chimei Musical Instrument Co., Ltd. in China.

DHS harmonicas are produced by Jiangsu Chimei Musical Instruments Company, and are also called Chimei harmonicas on the market (but Chimei is a trademark of another brand).

DHS (a joint venture) currently mainly produces polyphonic harmonicas and blues harmonicas for beginners and teaching harmonicas, so the types and prices are mostly low-priced and high-quality harmonica products.
