<p>A time-announcing device, comprising a casing and buttons. Button placement platforms are arranged on the casing. The button placement platforms are provided with recessed portions. The buttons are arranged on the recessed portions. The height of the buttons is smaller than the depth of the recessed portions. Since the height of the buttons is smaller than the depth of the recessed portions, the buttons do not protrude from the surface of the casing and cannot easily be pressed by mistake, which affects normal use of the time-announcing device.</p> |
