Abstract
Abstract A Digital Recording Center having a removable playback module for permanently capturing a human voice or other sounds into a compact module for playback within a greeting card or photograph. A recording center having a microphone (or other audio input device) is used to record a brief message, in a digital fashion, for loading into a playback module. Before loading the message into the playback module, the customer may listen through a speaker to determine if his message as recorded sounds proper. If the temporarily recorded message is in good form, the customer activates a transfer command button and the message is non-volatilely stored in the removable playback module. The playback module may be placed into a compartment within a greeting card or picture, ornament, a stuffed animal or doll, or even a dog tag.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
210 words
A system comprising a sound-recording apparatus and a miniature, self-contained, sound-playback module wherein the recording apparatus comprises: temporary-storage means for recording sound; means for playing back the sound as recorded by the temporary-storage means so that a user of the system can determine whether the recording is satisfactory, the temporary-storage means being capable of re-recording the sound if the user of the system so wishes; and means for transferring the sound as recorded or re-recorded by the temporary-storage means to the playback module as a digital signal; and wherein the playback module comprises: a digital memory for storing the digital signal, the digital memory being capable of activation to generate a digital output signal corresponding to the stored digital signal; a digital-to-analog converter connected to the memory for converting the digital output signal to an analog signal; speaker means responsive to the analog signal for reproducing the sound; a power source for powering the memory, digital-to-analog converter and speaker means; and activator means controllable by a user of the playback module to activate the memory to produce the digital output signal, thereby causing the speaker means to reproduce the sound as recorded by the recording apparatus; and further comprising connecting means releasably connecting the playback module to the recording apparatus.
Claim 2
Independent Claim
210 words
A system comprising a sound-recording apparatus and a miniature, self-contained, sound-playback module wherein the recording apparatus comprises: temporary-storage means for recording sound; means for playing back the sound as recorded by the temporary-storage means so that a user of the system can determine whether the recording is satisfactory, the temporary-storage means being capable of re-recording the sound if the user of the system so wishes; and means for transferring the sound as recorded or re-recorded by the temporary-storage means to the playback module as a digital signal; and wherein the playback module comprises: a digital memory for storing the digital signal, the digital memory being capable of activation to generate a digital output signal corresponding to the stored digital signal; a digital-to-analog converter connected to the memory for converting the digital output signal to an analog signal; speaker means responsive to the analog signal for reproducing the sound; a power source for powering the memory, digital-to-analog converter and speaker means; and activator means controllable by a user of the playback module to activate the memory to produce the digital output signal, thereby causing the speaker means to reproduce the sound as recorded by the recording apparatus; and further comprising connecting means releasably connecting the playback module to the recording apparatus.
