Abstract
A toy telephone includes a telephone base enclosure a microphone, a speaker, a memory chip for recording sounds for later retrieval, a microprocessor electrically connected to the memory chip, and at least one button electrically connected to the microprocessor for selecting one of a plurality of segments of the memory chip for recording. The memory chip is configured to produce an output signal the duration of which has a known mathematical relationship to the recording capacity of each of the plurality of segments of the memory chip. The microprocessor is programmed to receive an electrical signal from a button upon depression of the button, to select one of the segments of the memory chip in response to the depression of the button, to measure the duration of the output signal of the memory chip, to determine the recording capacity of the segment of the memory chip based on the duration of the output signal, to initiate recording of sounds received by the microphone into the segment of the memory chip, to terminate recording of the sounds when the recording capacity of the segment of the memory chip as determined by the microprocessor has been fully utilized, and to cause the sounds to be played at a later point in time.
