ABSTRACT:
An integrated device, used for selectively generating waking vibrations or sounds in alarm watches or in communications equipment such as cellullar or pager phones, is disclosed. In the device, first and second vibration members are set in a ring case and respectively generate waking vibrations and waking sounds. The second vibration member is made of a synthetic resin film, with two inner terminals being connected to both ends of a coil. A lead panel integrally extends from the edge of the second vibration member, thus being exposed to the outside of the device. Two outer terminals are provided on the outside end of the lead panel and are connected to the inner terminals through copper wires, thus connecting the coil to a PCB. The second vibration member, originally used for generating waking sounds, is thus used as a circuit board for the coil.
