Abstract
An electronic timepiece, which comprises a circuit for encoding an externally supplied voice and a semiconductor memory for memorizing the encoded voice data. The voice data memorized in the semiconductor memory is read out when a preset time is reached, and the data thus read out is converted into a voice signal which is coupled to a sound producing device such as a loudspeaker for the reproduction of the voice.
Claims18
An electronic timepiece comprising:
- time counter means for counting a reference frequency signal to form time data;
- time display means coupled to said time counter means for displaying said time data;
- first converting means for converting an externally provided voice sound into voice data;
- a semiconductor memory coupled to said first converting means for storing said voice data;
- address assigning means coupled to said semiconductor memory for sequentially assigning addresses of said semiconductor memory;
- second converting means coupled to said semiconductor memory for converting said voice data stored in said semiconductor memory into a voice signal;
- voice reproducing means coupled to said second converting means for generating a voice sound in accordance with said voice signal;
- externally operable switch means for enabling said semiconductor memory to store said voice data;
- voice data writing instructing means coupled to said externally operable switch means and to said address assigning means for supplying a writing instruction signal, generated by operating said externally operable switch means, to said address assigning means and to said first converting means to enable storing of said voice data from said first converting means in said semiconductor memory;
- alarm signal generating means coupled to said time counter means for generating an alarm signal when said time data coincides with a predetermined alarm time;
- and
- voice readout control means coupled to said alarm signal generating means for supplying said alarm signal as a readout instruction signal to said address assigning means and to said second converting means to enable said second converting means to convert said voice data stored in said semiconductor memory into said voice signal so that said voice reproducing means generates a voice sound corresponding to said voice signal.
