The present invention relates to a personal alarm apparatus and system to deter or stop various types of aggressors, particularly bears or other dangerous animals. The apparatus is capable of being activated by the user/victim or, if the victim is unable to activate the apparatus in time, the alarm apparatus may be activated by the actions of an attacker upon initiating the attack, The apparatus is compact, inexpensive, simple to use, and has a loud and long lasting sound that can stun or deter even large animals, such as bears. Optionally, it is capable of discharging smoke as an added means of frightening an attacker such as a bear. In one embodiment the self-defense alarm apparatus comprises a generally spherical container for a pressurized fluid. The container has an opening with an elongate, open-ended, cone element extending into the container. A sound transducer, such as a whistle, is located within the cone element. A plug element is located at an outer end of the cone element, and includes a pin element which, upon activation, allows the pressurized fluid to escape through the cone element and sound transducer to create a desired noise.
