BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a voice memory device, particularly portable, as a voice memory device for practicing language or music.

Recently, as the wave of internationalization has increased, interest in foreign languages has increased, and a language exerciser with a portable voice memory device that can practice foreign language conversation at any time has been proposed.

Such a language practice has been proposed to include a magnetic card recording a single voice data corresponding to a series of sentences and a reproducing control device for outputting the voice data of the magnetic card as a reproducing sound through earphones. Specifically, the playback control device reads the voice data from the magnetic card upon insertion of the magnetic card, transfers the voice data to the internal memory device, and outputs the voice data stored in the internal memory device as reproduced sound.

In the above-described conventional configuration, only one piece of magnetic data is stored on one magnetic card. Therefore, in order to practice conversation corresponding to several sentences, it is necessary to carry several magnetic cards. It is inconvenient in use.

In addition, it is inconvenient in this regard because it is necessary to change the magnetic card every time the practice contents are changed, and the time to transfer the voice data of the magnetic card to the internal storage device becomes relatively long.

In addition, a card transmission mechanism including a motor and a flywheel, a magnetic head, and the like are required to read voice data from the magnetic card, which leads to a complicated structure and an increase in the failure rate.

In addition, the above-described card transfer mechanism consumes a relatively large amount of power, and thus, when the power source is used as a battery for carrying, continuous usability is reduced, and when a large capacity battery is used, the weight increases, which causes problems in portability.

And especially in portability, since the weight of the card transfer mechanism itself is relatively large, it becomes a further serious problem.

In addition, since magnetic cards are susceptible to the influence of magnetic fields, it is necessary to pay attention to not placing magnets around, which is not desirable in terms of so-called simplicity. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and its object is to improve portability and usability at the time of carrying out, and thus to effectively practice language such as speech, and to increase the reliability of life. To provide memory.

The voice memory device according to the present invention is configured to digitally store and store a plurality of voice data in a solid memory circuit embedded in a card-like external memory device, and to store the solid memory circuit in a state where the external memory device is installed. A control device for integrally reading and converting voice data into analog voice signals and a reproducing device for outputting analog voice signals as reproduction sounds are provided.

If any of the digital voice data stored in the solid state memory circuit having the external memory device is designated as the control device with the external device mounted thereon, the voice data is read and converted into an analog voice signal and the playback device The reproducing sound corresponding to the above-mentioned analog audio signal is output from the.

At this time, since a plurality of voice data are stored in the solid state memory circuit, the user can select and listen to arbitrary voice data, so that they can practice language, music, and the like.

Hereinafter, an embodiment in which the present invention is applied to a language exerciser will be described with reference to the drawings.

In Fig. 2 showing the overall appearance, " 1 " is a main body case forming a flat rectangular container shape, in which a key input portion 2 having a plurality of key switches 2a, a buried microphone 3 and a liquid crystal are provided on the front thereof.

A 9C is an IC card, which is an external memory device configured to be inserted into or removed from the card insertion slot 5, and includes a PROM chip, a read-only memory device, a RAM chip, a read / write memory device, and a CPU chip. The memory IC 10, which is a solid state memory circuit, is embedded.

In this case, in the memory IC 10, for example, voice data corresponding to several sentences in a foreign language is digitized and stored. An example of the address map is shown in FIG. On the side of the IC card 9, a plurality of contacts 11 for signal input and output are provided. In the state where the IC card 9 is inserted into the card insertion opening 5, the contact 11 is inserted into the main body case 1. It is comprised so that it may be connected to the connector (shown with the code | symbol 12 in FIG. 1).

In Fig. 1, reference numeral 13 denotes a control device, which is a speech analysis synthesis circuit including a control circuit 14 including an microcomputer, an A-D converter, a DA converter, and the like, in addition to the above-described key input unit 2. 15) the signal switching circuit 16, for example, an internal memory 17 made of RAM.

At this time, the signal switching circuit 16 has a first state allowing data transmission and reception through the connector 12 between the voice analysis synthesis circuit 15 and the memory IC 10, which is an external memo fl, and the voice analysis synthesis circuit ( And a data selection function for selecting a second state that allows data transmission and reception with the internal memory 17 to and from the internal memory 17, and the switching to each state is performed by the control circuit 14.

The speech analysis synthesis circuit 15 performs an A-D conversion operation for converting digital voice data Sd input through the microphone 3 and the control circuit 14 in the memory IC 10 or the internal memory 17. The D-A conversion operation of reading the voice data designated by the ") and synthesizing the analog voice signal Sa according to the read digital voice data Sd is selectively executed. After the signal is terminated, an end signal is issued to feed back to the control circuit 14. Then, the control circuit 14 uses the LCD 4, the voice analysis synthesis circuit 15, and the signal based on various commands inputted from the key input unit 2, data transfer with the control program stored in advance and the internal memory circuit. Control of the switching circuit 16 and address control of the memory IC 10 and the internal memory 17 are executed as described later.

18 is a reproducing apparatus, which is configured to include an amplifier 19 in addition to the above-described volume 7 and earphones 8, and the above-described amplifier 19 has a volume (7) in the speech analysis synthesis circuit (15). The amplified analog audio signal Sa is input to the earphone 8.

Therefore, when the analog voice signal Sa is output from the voice analysis synthesis circuit 15, the reproducing sound corresponding to the voice signal Sa is output from the earphone 8, and the volume at this time can be adjusted by the volume 7. have.

In the following, the control content by the control circuit 14 will be described together with the overall operation.

(1) When recording voice

In this case, the key input unit 2 selects whether the recorded data is to be stored between the memory IC 10 and the internal memory 17. When such a selection is made, the control circuit 14 switches the signal switching circuit 16 to either the first state or the second state according to the input from the key input unit 2.

The control circuit 14 converts the voice analysis synthesis circuit 15 to the A-D conversion operation execution state when the recording command is given by the key input unit 2, and the memory IC 10 or the internal memory 17 The recordable time is calculated according to the data storage state, and the result of the calculation is displayed on the LCD4.

At this time, the ratio between the recordable time and the maximum allowable recording time may be displayed. When the voice is input through the microphone 3 in this state, the voice analysis synthesis circuit 15 converts the voice into digital voice data Sd, and the digital voice data Sd is stored in the memory IC 10 and the internal memory (Sd). The data is stored (that is, recorded) at a predetermined address of the one selected as described above in 17).

Then, the control circuit 14 performs recomputation of the recordable time and display change of the LCD 4 in accordance with the above-described recording.

(II) In the case of reproducing voice data stored in the memory IC 10 and the internal memory 17 In this case, the digital audio data (I) stored in the memory IC 10 and the internal memory 17 is supplied to the user. By the key input unit 2 selects the audio data desired to be reproduced from the one recorded in the memory and previously stored in the memory 10.

When such a selection is made, the control circuit 14 switches the signal switching circuit 16 to either the first state or the second state according to the command from the key input unit 2, and the selected voice. The type of data (an address in which voice data is stored) is displayed on the LCD4.

The control circuit 14 converts the speech analysis synthesis circuit 15 to the D-A conversion operation execution state when the playback command is given from the key input section 2. Thus, the speech analysis synthesis circuit 15 stores the memory IC 10. And the voice data selected as described above among the voice data stored in the internal memory 17 are read directly from the memory IC 10 or the internal memory 17 and given to the voice analysis synthesis circuit 15.

Then, the voice analysis synthesis circuit 15 converts the digital voice data Sd read as described above into an analog voice signal and gives it to the reproducing apparatus 18, so that the reproducing sound is output from the earphone 8.

When the output of the reproduced sound is finished, the control circuit 14, which has received the end signal from the speech analysis synthesis circuit 15, repeats the output operation of the reproduced sound for the predetermined number of times by the key input unit 2. As shown in FIG. In short, the user can listen to the voice data corresponding to several sentences previously stored in the IC card 9 and the voice data recorded by the user only by selectively or randomly reproducing the sound, thereby effectively practicing the language's hearing and speaking practice. You can run

According to the present embodiment described above, various effects as follows can be obtained.

That is, since the audio is reproduced using the IC card 9 in which the voice data corresponding to the multiple sentences are stored, it is possible to practice the multiple sentence hearing simply by carrying one or several pieces of the IC card 9. This improves portability and makes it convenient in practical use.

In addition, since the voice can be recorded, the practice of speaking can be performed in parallel, thereby improving the efficiency of language training.

Since data reading from the IC card 9 is much faster than that of the conventional magnetic card, it is possible to quickly reproduce the desired sentence, making it convenient to use.

Since the memory IC 10 of the IC card 9 is directly accessed, a mechanical part having a complicated structure is not required as in the prior art, thereby reducing the failure rate and reducing the current consumption and weight.

As a result, when the battery is used to carry the battery while increasing the reliability of the life, it is possible to further extend the continuous use time and further improve the portability. Since the IC card 9 does not have to consider the destruction of data by magnetism, its handling becomes easy.

In the above-described embodiment, the memory IC 10 stores the voice data corresponding to the sentence of a foreign language, but instead, it is possible to store the voice data corresponding to the music or the like. For example, the so-called music by the orchestra performance is stored. It can function as a music exerciser for karaoke, and also as a portable device for wildlife observation by memorizing crying sounds of wild birds. In the above embodiment, the recording function is added, but this may be provided as necessary.

According to the present invention, as described above, a configuration in which a card-like external memory device having a built-in solid state memory circuit in which a plurality of voice data are digitized and stored is provided to output sound data stored in the above-described solid state memory circuit as reproduced sound. It is possible to improve portability and usability at the time of carrying out the exercises, so that the language practice can be carried out efficiently and the reliability of the life can be improved and the continuous usability can be improved when the battery is used as the power source. Excellent effect can be obtained.
