There is provided an acoustic radiating membrane arrangement for a striking or musical watch. The arrangement includes a first membrane arranged superposed on a second membrane. Peripheral edge portions of the two membranes are intended to hold the membranes inside a watch case. The first acoustic radiating membrane is configured to radiate efficiently the frequencies in a first frequency band. The second acoustic radiating membrane is configured to radiate efficiently the frequencies in a second frequency band that is different from the first frequency band. A spacer ring is also disposed between the peripheral edge portions of the first membrane and of the second membrane to define an acoustic cavity.
