ABSTRACT:
A firearm (W) is for discharging a projectile such as bullet (B) through a barrel (L). The firearm includes a firing mechanism (F) for firing the bullet through the barrel. The firing mechanism includes a trigger (T) which is operable by the person using the firearm to fire the weapon. A firing pin (P) is operatively connected to the trigger for contacting a cartridge (C) and effecting discharge of the bullet. A gun lock (200) is provided to inhibit operation of the firing mechanism by enclosing trigger (T). A cover piece (202) fits about the trigger. A blocking pin (228) fits behind the trigger and is movable by an electro-magnet (240) which is activated by a processor (218) which evaluates a word or phrase spoken into an audio recognition unit (214) mounted on the cover piece. Received audio signals are directed to the audio recognition unit. If a received audio input corresponds to a predetermined audio frequency signal, the blocking element is moved from its inhibiting position to its enabling position.
