It has an input control part etc. to control. The control unit 12 controls each component comprehensively based on a signal sent when the plurality of buttons 11 are pressed to operate various functions as a language learning machine. . For example, the learning program selected by the button 11 is executed, the display is switched between Japanese display and English display, and the volume is adjusted.

In addition, the control unit 12 has a function of outputting audio information stored in the memory 13 from the two earphones 3 via the audio conversion unit 16. Thereby, for example, it is possible to learn by listening to a foreign language with a correct voice (native voice). At this time, the control unit 12 displays audio output information on the display unit 10. Therefore, the user can learn language with eyes and ears. That is, the control unit 12 and the voice conversion unit 16 function as the voice output unit 4.
The control unit 12 displays not only audio output information but also various other information on the display unit 10 in accordance with the operation of the button 11. For example, the contents of the learning program, the voice reproduction speed, the time, the date, the remaining amount of the dry battery 15 and the like can be displayed.

  The audio conversion unit 16 also functions as a stereo adjustment unit that adjusts the output level of the sound output from the two earphones 3. As a result, the sound can be heard from the two earphones 3 in a stereo state with an optimum volume.

  The earphone 3 includes a cord 3a that is attached to the case body 2 so that the proximal end of the earphone 3 can be inserted and removed, and an insertion portion 3b that is disposed at the distal end of the cord 3a and can be inserted into the ear. As shown in FIG. 3, the cord 3 a is inserted and removed through an insertion hole 5 d provided in the storage chamber 5. In the present embodiment, the base end side of the cord 3 a can be wound by the winding means 20 provided in the case body 2.

As shown in FIG. 4, the winding means 20 is supported by a shaft member 21 and the shaft member 21 so as to be rotatable around the axis L, and the cord 3 a is disposed on the outer peripheral surface between the two flanges 22 and 23. A reel 24 that can be wound and a coil spring 25 that urges the reel 24 in one direction around the axis L (the R direction shown in FIG. 4) are provided.
The shaft member 21 is fixed in a state of being formed in a columnar shape and facing in a direction perpendicular to the upper surface of the case body 2. The reel 24 is formed with a recess 24a for accommodating the coil spring 25 at the center. The coil spring 25 is housed in the recess 24a, and both ends are attached to the inner peripheral surfaces of the shaft member 21 and the recess 24a, respectively. As a result, the reel 24 is always biased in one direction (R direction).

  Moreover, the notch part 23a is formed in the one flange 23 among the two flanges 22 and 23 for every predetermined angle. A stopper 26 is provided at a position adjacent to the reel 24 so as to be rotatable about the pin 27. The stopper 26 is formed with a hook-like claw 26a that engages with the notch 23a. The reel 24 is prevented from rotating in one direction (R direction) described above when the claw portion 26a and the notch portion 23a are engaged. Further, the tip of the stopper 26 is formed in, for example, an arc shape so as not to prevent the rotation when the reel 24 is rotated in the other direction (the direction opposite to the R direction shown in FIG. 4).

  The stopper 26 is urged toward the one flange 23 by a claw 26a by a spring or the like (not shown). Further, the base end side of the stopper 26 is mechanically connected to a winding button (not shown) provided on the case body 2 so that it rotates with a force against the spring when the winding button is pressed. It has become. Thereby, the engagement between the claw portion 26a and the notch portion 23a is released, and the reel 24 is rotated in one direction by the coil spring 25. The cord 3a can be wound into the case body 2.

  As shown in FIGS. 2 and 3, the storage chamber 5 is formed in a state of being recessed inward from the surface of the case main body 2, and stores the earphone 3 and the sound output from the stored earphone 3 on the inner wall. The air vibration caused by the sound is amplified by reverberating at 5a. More specifically, the storage chamber 5 includes an inner wall 5a having a tapered cross section whose diameter gradually decreases inward from the surface of the case body 2 and a shielding plate 5b that shields one end side of the inner wall 5a. In the present embodiment, the enclosed space is formed on the upper surface of the case body 2 that is the same surface as the plurality of buttons 11 and the display unit 10.

  The two storage chambers 5 are formed so as to sandwich a plurality of buttons 11 therebetween, as shown in FIG. Further, the inner wall 5a and the shielding plate 5b may be formed integrally with the case main body 2 or may be attached to the case main body 2 after being formed of an optimum material that resonates sound. Further, as shown in FIG. 3, a concave portion 5c in which a part of the insertion portion 3b of the earphone 3 is accommodated and the above-described insertion hole 5d through which the cord 3a is inserted are continuously formed at the approximate center of the shielding plate 5b. Has been.

The cover 6 is displaceable between a closed position P1 for closing the inside of the storage chamber 5 as shown in FIG. 2 and an open position P2 for opening the inside of the storage chamber 5 as shown in FIG. And a diaphragm 6a that vibrates due to air vibration amplified by the inner wall 5a of the storage chamber 5.
More specifically, the cover portion 6 includes a ring portion 6b formed in an annular shape in accordance with the opening of the storage chamber 5, and the diaphragm 6a fixed to the inside of the ring portion 6b. The diaphragm 6a is formed by molding a metal plate such as ultrathin magnesium having high damping performance, for example. The cover 6 is fixed to the case body 2 near the opening of the storage chamber 5 through a hinge 6c so as to be opened and closed.

Next, the case where the portable language learning machine 1 configured as described above is used will be described below.
First, when learning using the earphone 3, as shown in FIG. 5, the two cover parts 6 are rotated around the hinge part 6c, respectively, and displaced from the closed position P1 to the open position P2. Thereby, the inside of the storage chamber 5 will be in the open state. Next, the insertion portion 3b of the earphone 3 stored in each of the two storage chambers 5 is grasped by a finger and pulled out from the storage chamber 5 to the outside. At this time, the cord 3a connected to the insertion portion 3b is pulled out from the case body 2 through the insertion hole 5d.

  That is, when the cord 3a is pulled out with a force against the coil spring 25 as the insertion portion 3b is pulled out, the reel 24 shown in FIG. 4 rotates in the other direction (the direction opposite to the R direction). At this time, since the stopper 26 does not hinder the rotation of the reel 24 in the other direction due to the shape of the tip, the cord 3a can be pulled out smoothly. Then, the cord 3a is pulled out to a certain length. When the drawing of the cord 3a is completed, the reel 24 is urged by the coil spring 25 to rotate in one direction (R direction), and the claw portion 26a of the stopper 26 is engaged with the notch portion 23a of the flange 23. Thereby, the cord 3a is maintained in the drawn-out state.

Next, as shown in FIG. 6, the user inserts the inserted insertion portion 3b into the ear and wears the earphone 3. In addition, after the earphone 3 is attached, the cord 3a can be wound up to optimally adjust the length of the cord 3a. That is, the winding button provided on the case body 2 is pressed to rotate the stopper 26 away from the reel 24. Then, since the engagement between the claw portion 26a and the notch portion 23a is released, the reel 24 is rotated in one direction (R direction) by the coil spring 25. Thereby, the cord 3a can be wound into the case main body 2, and the length of the cord 3a can be adjusted to be short. When the pressing of the winding button is stopped, the stopper 26 comes into contact with the reel 24 again by the spring, and the claw portion 26a and the notch portion 23a are engaged. Therefore, the winding of the cord 3a can be stopped.
Thus, by pressing the winding button, the extra length of the cord 3a can be adjusted and adjusted to an optimum length.

  Next, the button 11 is pressed as appropriate, and the audio information stored in the memory 13 is output by the audio output means 4. For example, English example sentences are output with correct voice. The user can clearly hear this sound with both ears using the earphone 3 even when the surrounding sound is troublesome (in a train or in a bus). Moreover, since voice output information, that is, English example sentences are displayed on the display unit 10, the user can learn English with eyes and ears.

  Next, when learning without using the earphone 3, the insertion portion 3b is put into the storage chamber 5 and the earphone 3 is stored while the winding button is pressed to wind the cord 3a. Next, the cover portion 6 is rotated around the hinge portion 6c to be displaced from the open position P2 shown in FIG. 5 to the closed position P1 shown in FIG. Thereby, the interior of the storage chamber 5 is closed by the cover portion 6. That is, as shown in FIG. 3, the earphone 3 is placed in a space surrounded by the inner wall 5 a and the shielding plate 5 b of the storage chamber 5 and the cover portion 6. Then, after the earphone 3 is stored, the buttons are pressed again as appropriate, and the audio information stored in the memory 13 is output by the audio output means 4. For example, as in the case of using the earphone 3, an English example sentence is output with correct voice.

Then, the sound output from the earphone 3 reverberates on the inner wall 5 a of the storage room 5. Therefore, the air vibration generated by the sound output is amplified and propagates to the diaphragm 6a of the cover unit 6. Thereby, the diaphragm 6a vibrates by the amplified air vibration and transmits the sound to the outside with a louder sound. That is, the earphone 3 can function as a speaker.
As a result, it is possible to clearly hear the sound at a volume that cannot be produced by the earphone 3 alone. Therefore, when using the user in a quiet environment such as a room, the user can clearly hear and learn the sound without wearing the earphone 3 on the ear.

  In particular, according to the portable language learning device 1 of the present embodiment, since the earphone 3 can function as a speaker, it is not necessary to separately provide the earphone 3 and the speaker as in the prior art. Therefore, the installation space for the speaker can be eliminated, the size can be reduced, and the configuration can be simplified. Further, since the earphone 3 can be made to function as a speaker simply by storing the earphone 3 in the storage chamber 5 and positioning the cover 6 at the closed position P1, the audio output destination is switched between using the speaker and using the earphone 3 by a switch or the like. No operation is required. Therefore, the operability can be improved. In addition, when the cover portion 6 is displaced, it is simply opened and closed with the hinge portion 6c as the center, so that the position between the closed position P1 and the open position P2 can be easily and instantaneously displaced. Therefore, it is easy to use and excellent in operability.

  In addition, since two earphones 3 are provided, it is possible to learn by wearing them in both ears. Therefore, even when the surrounding sound is particularly troublesome, it is possible to hear the sound clearly by blocking the external sound more reliably. It is not always necessary to use two earphones 3, and only one earphone 3 may be used. Further, by using two earphones 3, it is possible to listen to audio in a stereo state with an optimum volume. Therefore, functionality can be improved.

Further, since the sound output means 4 can be controlled by the button 11, the sound output timing and desired sound information can be reliably output. Moreover, since the audio output information is displayed on the display unit 10, it is possible to perform an accurate operation and to learn with eyes and ears, which is excellent in learning efficiency. Further, since the length of the cord 3a can be adjusted to an optimum length according to the use situation, the cord 3a does not get in the way and does not feel bothersome. Therefore, it is easy to use.
In addition, since the storage room 5 is provided on the same surface as the button 11 and the display unit 10, when the earphone 3 is stored in the storage room 5 and functions as a speaker, a voice is transmitted to the user. Can be output. Therefore, it is easy to hear the sound also in this respect.

(Second Embodiment)
Next, a second embodiment of the portable electronic device according to the present invention will be described with reference to FIGS. Note that the same reference numerals in the second embodiment denote the same components as those in the first embodiment, and a description thereof will be omitted.
The difference between the second embodiment and the first embodiment is that, in the first embodiment, the storage chamber 5 is provided on the upper surface of the case body 2 that is the same surface as the plurality of buttons 11 and the display unit 10. In the embodiment, the storage chamber 5 is provided on the lower surface of the case body 2. In the first embodiment, two earphones 3, a storage chamber 5 and two cover portions 6 are provided. However, in the second embodiment, only one earphone 3, the storage chamber 5 and one cover portion 6 are provided. It is.

Specifically, the fitting hole 31 is a circular hole formed in the shielding plate 5b with substantially the same diameter as the outer shape of the insertion portion 3b. The fitting hole 31 is configured to press and hold the periphery of the inserted insertion portion 3b with a predetermined force. Further, the inner wall 5a of the storage chamber 5 of the present embodiment is not tapered in cross section, and is formed perpendicular to the upper surface and the lower surface of the case body 2.

The portable language learning machine 30 configured in this way is different from the first embodiment in that the earphone 3 can be heard only with one ear when using the earphone 3, but other than that is the same as the first embodiment. The effect of this can be achieved. In particular, since the storage chamber 5 is provided on the lower surface of the case main body 2, the case main body 2 can be made smaller by the amount corresponding to the storage chamber 5, and the display unit 10 can be designed larger by the amount corresponding to the storage chamber 5. .
Further, the earphone 3 can be stored in a state in which the earphone 3 is not simply stored in the storage chamber 5 but is firmly held in the fitting hole 31. Therefore, even if the earphone 3 is facing down during storage, there is no risk of wobbling or dropping. Therefore, stable sound can be output, and reliability can be improved.
