Abstract
Abstract A circuit for use with or built into a telephone set, that detects and intercepts the telephone company's ring signal, supressing the telephone set's existing ringer, and substituting instead, a user selected audio segment. A choice of audio segments may be made from an internal memory device or as downloaded from a supplier of such audio segments by high-speed modem. A synthesized stereo signal is generated so that an incoming phone call is announced by a high quality, stereo audio signal of ones choice such as the sound of wind, water or trees, animal sounds, music, or other sounds. Usable audio segments may be obtained via a built-in microphone or downloaded at high speed through the use of a built-in modem over phone lines.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
234 words
A telephone call announcement system interconnected between an incoming telephone line and a telephone set comprising: a ring detector connected to the incoming telephone line and producing an internal ring signal in response to incoming ringing signals; an off-hook detector connected to the telephone set and producing an off-hook signal in response to a user taking the telephone set off-hook; a controller connected to the ring detector and the off-hook detector and receiving the internal ring signal and off-hook signal respectively therefrom; a record and playback system connected to the controller, an audio output means, and a storage means, for recording on the storage means one or more audio segments and playing through the audio output means at least one of the audio segments; a modem connected to the controller and the telephone line, wherein the controller places a call to an external telephone system via the modem and downloads at least one audio segment from the external telephone system and wherein the downloaded audio segment is recorded by the record and playback system onto the storage means; and wherein the record and playback system plays at least one of the audio segments through the audio output means in response to the controller receiving the internal ring signal and playing continuously until one of (a) the internal ring signal is no longer received after a predetermined time or (b) the off-hook signal is received.
