ABSTRACT:
A sonic archery beacon (10) is disclosed which employs a circuit (21) carried by an arrow (1) which includes an audible signal generator being configured to mimic the sound of a naturally occurring insect, bird or the like. Circuit (21) is activated by an inertia switch (22) which is responsive to a drastic change in acceleration such as that experienced when an arrow impacts with an object, animal or the ground. The audible signal generator implements an oscillator (23) in combination with a miniature speaker or piezo electric transducer (24) having an output which mimics a cricket. Magnetic/mechanical inertia switch (22) has a magnet (32) slidably positioned within a tube (26) having ferromagnetic objects (34 and 35) at both ends of tube (26). When the magnet (32) is positioned at one end of the tube against the pair of and will close in response to the magnetic field of magnet (25) when the magnet is positioned at that end.
