Abstract

PURPOSE:To easily decide the meaning of an alarm tone by reading out and controlling a pair of storage circuits in which contents with different recognition rates each other are stored through different frequency signals respectively. CONSTITUTION:The operation mode of the titled clock is turned to a voice input mode by depressing a switch 16 to use a speaker as a microphone. The inputted voice is stored in the 1st storage circuit 9 through an I/O switching circuit 13 and an A/D converter 7. On the other hand, voice signals have been already recorded in the 2nd storage circuit 10 at the time of its production. When a coincidence circuit 5 detects an optional set time, a memory controlling circuit 8 is actuated to read out the contents of the storage circuits 9, 10, select any one of the circuits 9, 10 through a selecting circuit 11 and inform the recorded contents from a speaker 15 through the circuit 13. In said circuit configuration, a RAM and a ROM are used for the storage circuits 9 and 10 respectively, and at the reading out from the circuit 10, the frequency of a sampling frequency signal is increased and the circuit 9 is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic watch with a recording function that can record audio.

In recent years, electronic watches have become more multifunctional, and some are equipped with alarm functions and the like.

When an arbitrarily set alarm time is reached, a buzzer is driven by a specified frequency signal to sound a sound or a melody, and the LA is used.
fco However, the alarm sound could only be a fixed sound determined by the manufacturer or a melody. In the case of this unconventional function, it may not suit the user's tastes or may turn him off, and what's more, he has to remember when the alarm sounded to ask for it. I had to.

The present invention has been made to improve these drawbacks, and aims to provide an electronic timepiece that can be easily operated by the user and allows the user to easily determine what the alarm sound means.

2- One embodiment will be explained in detail below using drawings.

I will clarify.

FIG. 1 is a circuit diagram of an electronic timepiece with a recording function according to the present invention R11.

(2) is an oscillation circuit, which outputs the entire reference signal that becomes the time standard. The output of the oscillation circuit 1 is frequency-divided by a frequency divider circuit 2, and is frequency-divided into a low frequency wave required at the time of crying. And counter circuit 3
The time is measured by H1. 4 is an alarm setting counter circuit, which allows the user to arbitrarily set the time on the output signal of the switch Nt control circuit 6; 5 is detected, the memo 'I flil
The l m1 circuit 8 operates, and the first memory circuit 9. Alternatively, in the second note (read the contents of the three circuits 10 and select the selection circuit 11
Specifically, the first memory circuit 9. Alternatively, the encoded audio signal in the second storage circuit IO is selected and the digital-to-analog converter 12 (hereinafter referred to as D/Af converter-1-)
The input/output switching circuit 13 synthesizes the audio signal using
The signal is transmitted through the amplifier circuit and filter 14'ft, and a sound is output from the speaker 3-car 15'. When the switch 16 is operated to enter the audio input mode, an input control signal is inputted from the memory control circuit 8 to the input/output switching circuit 13 by the chatter prevention switch control path 6, and the speaker 15 is used as a microphone. It becomes ready for use. Then, when the audio is input, the Allilog digital converter 7
(hereinafter referred to as Aμ converter), the sound and sign are
The data is encoded and stored in the first storage circuit 9. When the alarm times match or when a switch is operated, the sound is outputted as described above.

As explained above, the audio signal written to the first memory circuit and interrupted is input by the user, especially in the case of a watch, and the recognition rate when listening to the audio is very high. It will be expensive. Father, the first memory circuit must be composed of a memory circuit that can be written to and read from (e.g. RAM), and depending on the sampling frequency used to encode the audio, this can result in a very large load. . For example, if the quantization is 6 bits and the sampling frequency is 1 (l K
Assuming Hz4-, a kilo-pit storage circuit is required to store one second of sound as Ft,&. However, the user
As explained above, products that use voice input have a very high recognition rate, so they can be used even if the sampling frequency is lowered (and the sound quality deteriorates).However, The audio signals stored in the second storage circuit 10 were created at the manufacturing stage, so the recognition rate is low.

However, since the second memory circuit 10 is a read-only memory circuit (ROM), when integrated into an IC, the
is very high.

For the above reasons, in the present invention, the first memory circuit 9 is
When the memory circuit 1 () is configured with a ROM and the data f in the second memory circuit 10 is read, the memory control circuit 8 is set to 1, and the selection circuit 11 is The data of the first storage circuit 9 is selected and supplied to the D/A converter, and the frequency of the sampling frequency signal that controls the readout of the second memory circuit 10 is selected and supplied to the D/A converter.

5- If the present invention is adopted as described above, the user can easily recognize the voice output for registration and the voice output built in at the manufacturing stage by simply adding a circuit. It is possible to reduce the burden on the IC of the memory circuit and reduce the burden on the IC.
Low tlff Overall low hit rate of the first storage circuit (,
Since the bit rate of the highly integrated second memory circuit is high, there is no problem with the product configuration.
