Combination emergency phone and personal audio device

Abstract

A combination personal audio device and emergency phone provides a user with personal audio entertainment while also providing full duplex wireless communication with an emergency response service. The apparatus includes an audio information access device, such as a compact disc player, for accessing audio information and generating an electrical audio information signal based upon the audio information. A transmitter generates an outgoing communication signal that is capable of reaching and being received by the emergency response service. A single emergency response switch is the user's sole means for activating the transmitter. When pressed, the emergency response switch activates the transmitter to generate the outgoing communication signal. A receiver receives an incoming communication signal from the emergency response service, and generates an audio communication signal based upon the incoming communication signal. An audio amplifier receives and amplifies the electrical audio information signal and the audio communication signal to produce an amplified electrical audio information and an amplified audio communication signal. A sound production device converts the amplified electrical audio information signal and the amplified audio communication signal into acoustical sound waves capable of being aurally perceived by the user. The apparatus includes an aural alarm, such as a siren, and a visual alarm, such as a flashing light, to alert individuals in an area surrounding the apparatus when an emergency situation exists.
