JPS60136829A - Writing method of voice in storage element - Google Patents

Abstract

PURPOSE:To exclude a rotary means and to attain stable operation by dividing a voice waveform with time, A/D converting the time-divided signal to use the digital signal as a data signal of a storage element, and using flock frequency to be time-divided as an address signal to write the address signal in the storage element. CONSTITUTION:A signal recorded at a micro-level is inputted to a slicer 9 (time division circuit) through a band pass filter 10, divided into ten parts at high frequency in an unaudible range e.g. and the divided signals are successively inputted to a CPU1 as data by a counter 7 through an A/D converter 8 and simultaneously used for controlling the addresses of the CPU1. The data obtained by said method are written in the storage device 3. At the time of reading, the counter 7 is stopped and the CPU1 is run, so that a voice is reproduced from a speaker 15 through an address bus 2, a data bus 5 and a D/A converter 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for directly writing to a memory element by voice.

Conventionally, in order to store data in a storage element (ROM or RAM), an address of the element is selected, and high-level and low-level signals corresponding to the address are written as data in binary numbers. In this case, the usual method is to select the address (A bus) by a counter or key input, and to select the data (D bus) for that address by key input. These are usually CPUs (Central Pr.

cessing Unit).

Therefore, in order to control the CPU, a dedicated =m is required (e.g., Microsoft's Bentzk or Mann), and there are also problems such as differences depending on the type of CPU (e.g., 68 series and 80 series are different). There is something that cannot be easily written.

It is an object of the present invention to provide a method that eliminates these problems and allows a person to directly write to a memory element and read data as well.

That is, when writing data to a memory element, the present invention separates a collected audio waveform into an effective frequency band using a bandpass filter, then time-divisions the waveform, AD converts the obtained time-division signal, and writes the data to the memory element. The gist of the present invention is to write data into a storage element using the clock frequency for time division as the address signal.

Hereinafter, in order to further clarify the gist of the present invention, one embodiment thereof will be described with reference to the drawings.

In Figure 1, C! A clock is applied to the PU1 by an oscillator 6. Then, the address of 0PU1 is transferred to the memory element 8 (for example, E
FROM or RAM) and connected to Pio4 (
input/output elements). Further, the data of the CPU 1 is connected to the data input of the storage element 3 via a data bus 5 (D bus), and is also connected to the notator input of FIO4 (input/output element). Data is input to the CPU 1 via the counter 7 and the AD converter 8.
, a slicer 9 (time division circuit) and a bandpass filter 10, and further connected from a low frequency amplifier 11 to a microphone 12.

On the other hand, the port of Pio 4 (input/output element) is connected to the digital converter 14 via the DA converter 13, and is further read directly to the speaker 15.

In the above configuration, to explain the function of each part, the sound is collected by the microphone 12 and amplified by the low frequency amplifier 11. As shown in FIG. It includes high frequencies exceeding .

Since the waveform shown in FIG. 2 is not suitable for the purpose of the present invention, unnecessary bands are removed by the bandpass filter 10, resulting in the waveform shown in FIG. 3.

The waveform shown in FIG. 1 and 8 is input to the next slicer 9 (time division circuit) and divided into 10 parts by, for example, a frequency in the inaudible range, and the waveform is shown in FIG.

The time-divided waveform is then input to the A'D divider 8 and converted into a binary number (in the case of the present invention, 1 byte is 8 bits). This data is sequentially (3P
It is input as data of U1 and also controls the address of 0PUI at the same time.

The waveform data obtained in this manner is then written into the storage element 8. In addition, when reading data, if the counter 7 is stopped and cPul is set to run, the data written in the memory element 3 is transferred to the Pio4 (input/output element) via the address bus 2 (A bus) and the data bus 5 (D path).
and outputs it as a binary number from an appropriate port (for example, the A port). This binary number is converted into an analog signal by the DA converter 18, and then shaped into the original waveform by an integrating circuit (not shown).
4 and vibrates the speaker 15 to reproduce it as sound.

The above explanation has been made assuming that writing, reading and reproducing are the same configuration, but if it is used for W writing or reading and receiving, the circuit configuration will be simple.

It should be noted that the memory element written in this way can of course be removed, and if inserted into the read-only circuit described above, the contents written in voice will be reproduced in voice.

As explained above, according to the present invention, writing (recording),
It has various superior features compared to other recording methods in both readout and playback. In other words, since it is a purely electric type, the rotating part (
Since there are no mechanical parts, it has a long life and can be manufactured at an extremely low cost. In addition, since there are no rotating parts, it can be made extremely small and compact, and it can operate extremely stably against vibrations and shocks.Furthermore, since it consumes extremely little power, it can be operated for a long time using small dry batteries, etc. It must be said that this is a very useful invention.

Claims (1)

[Claims] When writing data to the storage element, the collected audio waveform is separated into effective frequency bands by a bandpass filter, and then the waveform is time-divided, and the resulting time-division signal is AD-converted and used as a data signal for the storage element. On the other hand, there is a method for writing data into a memory element by voice, which is characterized in that data is written into the memory element using the clock frequency for performing time division as described above as an address signal.
