1. A door knocker apparatus, which comprises:
- (a) a body member enabled to be mounted on a door, said body member having a circuit board enclosed therein, said circuit board with processor, battery, clock, speaker driver, volatile and non-volatile memory, wherein said body member is attachable to a generally planar outside surface of a door;
(b) an acoustic speaker having an attachment to said body member and having an electronic connection to said speaker driver;
(c) a swingplate or swingarm having a first aspect with hinged mechanical connection to said body member and a second aspect having a permanent magnet disposed so as to electromagnetically actuate said processor by a repetitive knocking action defined by a movement of said swingplate or swingarm from a magnetically contacted to a non-contacted position relative to a Hall Effect sensor mounted on said body member, said Hall Effect sensor having an electronic connection for delivering an electrical signal to said processor; and
,further wherein said processor is programmed to actuate and modulate an output from said speaker driver so as to play a sound effect on said acoustic speaker when activated by said knocking action.
