Setting call/bell signal involves placing individually selected sounds or noises from external source into memory in sound acquisition/reproduction device for retrieval by initializing signal

摘要

The method involves placing individually selected sounds or noises from an external source into a memory in a sound acquisition and reproduction device. The sounds or noises are acoustically retrieved when an initializing signal is fed into the sound acquisition and reproduction device, e.g. a mobile or static telephone or a doorbell. A RAM chip can be used as the storage medium.
