Striking timepiece e.g. repeater watch, has case including unfolded walls that form resonance box and permit amplifying device to attain folded and unfolded positions, where amplifying device is extracted from case in unfolded position

摘要

The timepiece has a case including a backcover (2) and a middle (4) that define a housing for receiving a sound producing clock movement. The case has a sound amplifying device (8) provided with unfolded walls that permit the amplifying device to attain a folded position and an unfolded position, where the unfolded walls form a resonance box. The amplifying device is partially enclosed in the case in the folded position, and is extracted from the case in the unfolded position.
