Description

  The present invention relates to a speaker mechanism and an electronic apparatus including the same.

  Currently, a large number of electronic devices such as portable information terminals such as mobile phones and PDAs, electronic dictionaries and notebook personal computers are provided. This type of electronic device has a built-in speaker for outputting normal audio, and outputs various types of audio as required. Here, a general mounting structure of the speaker will be briefly described with reference to the drawings.

As shown in FIG. 27, the speaker 100 is generally directly fixed to the back surface of the casing 101 of the electronic device by screws or an adhesive. At this time, a plurality of sound emitting holes 102 are formed in the casing 101 where the speaker 100 is fixed. Note that a mesh member (for example, a saran net) 103 for waterproofing and dustproofing the speaker 100 is interposed between the housing 101 and the speaker 100.
In addition, the speaker 100 is housed in a housing room surrounded by a wall portion formed integrally with the housing 101. The storage room is composed of a rear air chamber R for reverberating the sound when the sound is output from the speaker 100.

  When sound is output from the speaker 100 under such a configuration, the sound from the front side of the speaker 100 passes through the sound output hole 102 and is output to the outside of the housing 101 as shown in FIG. At the same time, the sound emitted from the rear surface side reverberates in the rear air chamber R and then circulates to the front surface side of the speaker 100 and is output from the sound emitting hole 102 to the outside of the housing 101. That is, the sound output directly from the front side of the speaker 100 and the sound reverberated in the rear air chamber R are mixed and output.

By the way, when listening to various kinds of sound using an electronic device, there is a need to adjust the balance of sound output by changing sound quality, sound range, sound pressure, and the like depending on the kind of sound. For example, when listening to music and listening to language speech, there is a demand for listening to audio with an optimal audio output balance suitable for each.
However, as described above, the general speaker 100 is mounted in a limited space in the housing 101, and thus the volume of the rear air chamber R is predetermined. For this reason, the sound output balance cannot be changed as appropriate, and the above-described needs cannot be met.

On the other hand, a speaker device capable of changing the volume of the rear air chamber is known (see Patent Document 1). In this speaker device, a rear air chamber is constituted by a cylindrical member and a cup-shaped member that can be projected and retracted with respect to the cylindrical member. Therefore, the volume of the rear air chamber can be appropriately changed by allowing the cup-shaped member to appear and disappear. Thereby, the reverberation condition in the rear chamber can be appropriately changed, and the sound output balance can be changed.
Japanese Patent Laid-Open No. 2007-14283

  However, in this speaker device, since only the volume of the rear air chamber can be changed, the sound output balance can be changed, but there is a limit. In particular, in order to cope with various kinds of audio information in recent years, it is desired to change the audio output balance efficiently, but it is difficult to change the audio output balance efficiently only by changing the volume of the rear air chamber. In addition, since the space that can be secured in the housing of the electronic device or the like is limited, it is difficult to significantly change the volume of the rear air chamber. Therefore, the audio output balance cannot be changed efficiently.

  The present invention has been made in view of such circumstances, and a purpose thereof is a speaker mechanism capable of efficiently changing a sound output balance even in a limited space and an electronic device including the same. Is to provide equipment.

The present invention provides the following means in order to solve the above problems.
The speaker mechanism according to the present invention includes a speaker body and a storage body for storing a front air chamber on the front surface side of the speaker body and a rear air chamber on the rear surface side in an internal space in which the speaker body is closed. A positional relationship between the housing body and the speaker body, and a sound emitting hole that is formed in the housing body so as to communicate the front air chamber and the outside, and that outputs sound emitted from the speaker body to the outside. And a variable means for changing the volume ratio of the front air chamber and the rear air chamber to be relatively variable.

  In the speaker mechanism according to the present invention, when sound is generated by operating the speaker body, the sound is mixed while echoing in the front air chamber and the rear air chamber secured in the internal space of the storage body, Output to the outside through the sound emission hole. At this time, the positional relationship between the storage body and the speaker main body can be relatively varied by the variable means to change the ratio of the volume of the front air chamber and the volume of the rear air chamber. Therefore, it is possible to adjust the reverberation condition of the sound that reverberates in the front air chamber and the rear air chamber, and change the sound quality, sound range, sound pressure, etc. Can be changed.

  In particular, the volume ratio of the front air chamber and the rear air chamber can be changed, unlike the conventional one that can only change the volume of the rear air chamber. Therefore, the audio output balance can be changed more easily and more efficiently than before, and output adjustment corresponding to a wide variety of audio information can be performed. In particular, since both the front air chamber and the rear air chamber can be used, the sound output balance can be efficiently changed even in a limited space.

  In the speaker mechanism according to the present invention, the sound emitting hole for the bus that connects the rear air chamber and the outside is formed in the housing. In particular, the sound emitted from the rear side of the speaker body and reverberating in the rear air chamber has a lower sound range than the sound emitted from the front side. That is, the sound in the low frequency range is mainly used. Therefore, this low-frequency sound can be output to the outside from the bass sound emission hole. Therefore, in addition to the sound output from the sound emission hole formed on the front air chamber side, the sound in the low frequency range can be positively output from the sound emission hole for the bus. As a result, the audio output balance can be changed more efficiently, and the audio output can be adjusted.

Sometimes, the sound emission hole for the bus is blocked. That is, when the volume of the rear air chamber is sufficiently smaller than the volume of the front air chamber (for example, the ratio of the volume of the rear air chamber to the container of the front air chamber is 1: 9 or 2: 8). In such a case, the low-frequency sound cannot be sufficiently reflected in the rear air chamber, and the low-frequency sound output cannot be expected so much. Therefore, the sound emission hole for the bus is blocked. As a result, it is possible to prevent an unnecessary voice from being output from the sound emission hole for the bus.

(First embodiment)
Hereinafter, a first embodiment of an electronic apparatus according to the present invention will be described with reference to FIGS. In the present embodiment, an electronic dictionary will be described as an example of an electronic device.

  As shown in FIG. 1, the electronic dictionary 1 of the present embodiment is a foldable portable electronic device, and includes a bottom case 3 and a top case 4 that are connected to each other via a hinge portion 2 so as to be opened and closed. A casing (housing) 5 is provided. As a result, the top case 4 can be closed and folded when not in use, and can be easily stored and carried in a bag or the like, for example, in a thin and compact size. In use, the top case 4 is rotated with respect to the bottom case 3 so that the angle of the top case 4 can be adjusted so as to match the user's eyes.

  The bottom case 3 and the top case 4 are formed in a thin box shape as a whole by appropriately using a metal material such as plastic, aluminum, and stainless steel. Among these, the bottom case 3 has a two-stage structure in which the bottom cabinet 3a and the top cabinet 3b overlap. And in this bottom case 3, the speaker mechanism 20 mentioned later is each incorporated in the left and right. That is, the electronic dictionary 1 of the present embodiment is a stereo type that can output sound from the left and right.

Here, the speaker mechanism 20 will be described. Since the left and right speaker mechanisms 20 have the same configuration, only one speaker mechanism 20 will be described in detail.
As shown in FIGS. 2 to 4, the speaker mechanism 20 outputs a speaker main body 21, a storage body 22 that stores the speaker main body 21 in an internal space, and a sound emitted from the speaker main body 21 to the outside. A sound emitting hole 23 and variable means 24 for relatively changing the positional relationship between the housing 22 and the speaker main body 21 are provided.

  The storage body 22 has a pair of cup-like members 27 arranged with their openings facing each other, and a cylindrical shape that is slidably combined with both ends inserted from the opening side of the pair of cup-like members 27. The member 28 is mainly configured, and is built in the top cabinet 3b constituting the bottom case 3.

The pair of cup-shaped members 27 are formed so that a part of the outer peripheral surface becomes a flat flat surface 27a. The pair of cup-shaped members 27 are attached with flange plates 29 each having a screw hole 29a. On the other hand, the top plate of the top cabinet 3b is provided with a screwing member 30 having a thread groove formed on the inner peripheral surface.
The pair of cup-shaped members 27 are arranged at a constant interval so as to be linearly arranged in the lateral width direction (arrow A direction shown in FIGS. 1 to 3) inside the side surface of the top cabinet 3b and along the side surface. It arrange | positions in space and it is fixed to the top plate of the top cabinet 3b using the screw 31. FIG. Specifically, the cup-shaped member 27 is fixed by screwing the screw 30 inserted through the screw hole 29a into the screw groove in a state where the flange plate 29 is in contact with the screwing member 30. At this time, the pair of cup-shaped members 27 are fixed in a state where the flat surface 27a is in contact with the top plate of the top cabinet 3b.

The cylindrical member 28 is a long member formed in a cylindrical shape and extending in one direction, and both ends thereof are inserted into the pair of cup-shaped members 27 through openings. That is, both ends of the cylindrical member 28 are supported by the pair of cup-shaped members 27. In addition, the tubular member 28 can be slid in the lateral width direction (arrow A direction) of the top cabinet 3b.
The internal space of the pair of cup-shaped member 27 and cylindrical member 28 combined in this way is a closed space, and is used as a front air chamber R1 and a rear air chamber R2, which will be described later.

  A speaker body 21 is fixed inside a substantially central portion of the tubular member 28. At this time, the speaker main body 21 is fixed so as to be in contact with the inner peripheral surface of the cylindrical member 28 in a state where the front surface faces the one cup-shaped member 27 and the rear surface faces the other cup-shaped member 27. Has been. Thus, the internal spaces of the pair of cup-shaped members 27 and the cylindrical member 28 are in a state of being partitioned into two spaces with the speaker main body 21 as a boundary. Among these, the space on the front surface side of the speaker body 21, that is, the internal space mainly composed of one cup-shaped member 27 functions as the front air chamber R1, and the space on the rear surface side of the speaker body 21, that is, the other cup shape. An internal space mainly composed of the member 27 functions as the rear air chamber R2.

  In addition, the flat surface 27a of one cup-shaped member 27 is formed with a sound emission hole 23 that communicates the front air chamber R1 with the outside. Thereby, the sound generated from the speaker main body 21 is output to the outside through the sound emission hole 23 after reverberating in the front air chamber R1 and the rear air chamber R2. The speaker main body 21 is electrically connected to a control unit 15 described later, and its operation is controlled.

Incidentally, a slide shaft 31 having an insertion hole 31 a formed at the tip is formed on the outer peripheral surface of the substantially central portion of the cylindrical member 28 so as to be substantially orthogonal to the longitudinal direction of the cylindrical member 28. On the other hand, a slide hole 32 is formed on the side surface of the top cabinet 3 b so as to face the slide shaft 31. The slide hole 32 is a long hole formed long in the lateral width direction (arrow A direction), and functions as a guide hole that slides an insertion portion 34a of a slide switch 34 described later in the lateral width direction.
Further, a slide groove 33 is formed on the side surface of the top cabinet 3b so as to surround the periphery of the slide hole 32, and a slide switch 34 in which an insertion portion 34a is formed is slidably fitted in the slide groove 33. . The slide switch 34 can be slid from the outside of the top cabinet 3 b, and the tip is inserted into the insertion hole 31 a of the slide shaft 31 and fitted.

  Therefore, by sliding the slide switch 34, the cylindrical member 28 can be slid in the lateral width direction, that is, between the pair of cup-shaped members 27 via the slide shaft 31. That is, the position of the speaker body 21 can be varied with respect to the storage body 22. Thereby, the volume ratio between the front air chamber R1 and the rear air chamber R2 can be appropriately changed. That is, by sliding the cylindrical member 28 toward the one cup-shaped member 27 side, the volume of the front air chamber R1 is reduced and the volume of the rear air chamber R2 is increased, and the slide movement is performed toward the other cup-shaped member 27 side. By doing so, the volume of the front air chamber R1 can be increased and the volume of the rear air chamber R2 can be reduced.

That is, the slide switch 34 and the slide shaft 31 slide the cylindrical member 28 to relatively change the positional relationship between the storage body 22 and the speaker main body 21, so that the front air chamber R1 and the rear air chamber R2 It functions as a variable means 24 for changing the volume ratio.
In the present embodiment, the tubular member 28 is designed so as not to block the sound emission hole 23 when the tubular member 28 is slid and moved to the one cup-shaped member 27 side. Further, the surface of the slide switch 34 is an uneven surface 34b in which peaks and valleys are repeated, and is devised so that the fingertip does not slip during the slide operation.
However, the present invention is not limited to this case, and other methods may be used to prevent slipping. For example, it is possible to increase the frictional resistance by covering the surface of the slide switch 34 with rubber, or forming a plurality of minute convex portions, etc., and exhibit the anti-slip effect.

  A speaker hole 35 communicating with the sound emission hole 23 is formed in the top plate of the top cabinet 3b. The speaker hole 35 is fitted with a porous speaker cover 36 having a plurality of sound holes 36a to prevent intrusion of moisture and dust. Thereby, the sound emitted from the speaker body 21 flows from the sound emission hole 23 to the speaker hole 35 and is output to the outside from the speaker hole 35.

As shown in FIG. 1, the bottom case 3 in which the two speaker holes 35 are formed as described above has a keypad 10 in which a plurality of keys that can be pressed with a fingertip are arranged in a predetermined keyboard arrangement (keyboard arrangement). And an input unit 12 including a plurality of function switches 11 that can be pressed with a fingertip.
On the other hand, the top case 4 is provided with a display panel 13 for displaying various information input by the input unit 12 over almost the entire surface, and a transparent protective cover (for example, a plastic cover such as plastic). ) 14 is visible. The display panel 13 is a color or monochrome liquid crystal panel of about 5 inches, for example. Further, the protective cover 14 is not essential.

  Further, as shown in FIG. 5, the bottom case 3 contains a control board 15, a memory 16, a rechargeable battery 17, and a circuit board 18 on which various electronic components (not shown) are mounted. The control unit 15 includes an arithmetic processing unit such as a CPU, a ROM that stores various programs as the electronic dictionary 1, a RAM that is a temporary storage medium, a display control unit that controls the display panel 13, and the like. Yes. The control unit 15 comprehensively controls each component based on an input signal sent via the circuit board 18 when a plurality of keys on the keypad 10 or the function switch 11 is pressed, and electronically controls each component. Various functions are operated as the dictionary 1.

  In particular, the control unit 15 operates the speaker body 21 based on the input signal. In addition, the control unit 15 has a function of outputting sound information stored in the memory 16 from the speaker body 21. Thereby, it is possible to listen and learn the searched foreign language with the correct voice (native voice). At this time, the control unit 15 also displays audio output information on the display panel 13. Therefore, the user can check the search contents with his eyes and ears.

In particular, when learning by listening to native speech, the ROM according to the present embodiment can learn by listening to speech information of each country (for example, English speech, Italian speech, Japanese speech, etc.). The application is programmed. In addition, an application that can learn by listening to voices for each gender (voices for men and voices for women) is programmed. These different applications can be activated by pressing different function switches 11.
The control unit 15 displays not only the voice output information but also the key pressed with the fingertip on the display panel 13, or other various information (for example, the contents of the dictionary, the contents of the word search, the remaining amount of the rechargeable battery 17, Time, date, etc.) can be displayed on the display panel 13.

Next, the case where the electronic dictionary 1 configured in this way is used will be described below.
First, after placing the bottom case 3 on a flat surface such as a desk, the top case 4 is opened to a predetermined angle via the hinge portion 2 as shown in FIG. Various functions as the electronic dictionary 1 can be operated by appropriately pressing a plurality of keys and the function switch 11 of the keypad 10.
In particular, when one of the function switches 11 is pressed to learn with native speech, the control unit 15 recognizes from the input signal sent from the function switch 11 that the native speech learning function has been selected, The speaker body 21 is activated.

  Then, the speaker body 21 generates sound by vibrating a diaphragm (not shown). This sound is emitted from the front side and the rear side of the speaker main body 21, and mainly in the front air chamber R <b> 1 mainly composed of the internal space of one cup-shaped member 27 and the internal space of the other cup-shaped member 27. It reverberates in the rear air chamber R2 constructed. Then, after mixing while reverberating, the sound is output from the sound emitting hole 23 to the outside of the housing 22. The sound flows from the sound emission hole 23 to the speaker hole 35 and then is output to the outside through the speaker cover 36. Thereby, the user can learn while listening to the native voice.

Moreover, the user can adjust the sound output balance to an optimum sound output state by appropriately changing the sound output balance during the learning.
Specifically, the slide switch 34 provided on the side surface of the top cabinet 3b constituting the bottom case 3 is slid. Thereby, the cylindrical member 28 can be slid and moved via the slide shaft 31, and the volume ratio between the front air chamber R1 and the rear air chamber R2 can be changed. At this time, as shown in FIG. 6, when the cylindrical member 28 is slid and moved toward the one cup-shaped member 27, the volume of the front air chamber R1 can be reduced and the volume of the rear air chamber R2 can be increased. On the other hand, as shown in FIG. 7, when the cylindrical member 28 is slid to the other cup-shaped member 27 side, the volume of the front air chamber R1 can be increased and the volume of the rear air chamber R2 can be reduced. Thus, the volume ratio between the front air chamber R1 and the rear air chamber R2 can be easily changed by simply sliding the slide switch 34.

  Thereby, the reverberation state of the sound that reverberates in each of the front air chamber R1 and the rear air chamber R2 can be adjusted, and the sound quality, sound range and sound pressure of the sound output from the speaker hole 35 through the sound emission hole 23 can be adjusted. Etc. can be changed to change the audio output balance appropriately. Therefore, learning can be performed while clearly listening to the native speech.

  In particular, unlike the conventional one that can only change the volume of the rear air chamber, the electronic dictionary 1 of the present embodiment can change the volume ratio of the front air chamber R1 and the rear air chamber R2. Therefore, the audio output balance can be changed more efficiently than before, and output adjustment corresponding to a wide variety of audio information can be performed. Therefore, when listening to native audio, listening to audio information of each country or audio information for each gender, it is possible to listen with an optimal audio output balance according to the situation. Therefore, the electronic dictionary 1 is very easy to use and has high performance.

  In addition, since the speaker mechanism 20 uses both the front air chamber R1 and the rear air chamber R2, the sound output balance can be changed efficiently even in a limited space in the bottom case 3. Moreover, since the size of the storage body 22 itself does not change, the speaker mechanism 20 can be easily incorporated even in a limited space in the bottom case 3 and the design can be facilitated. In addition, in the present embodiment, the volume ratio between the front air chamber R1 and the rear air chamber R2 can be clearly changed with a simple configuration in which the cylindrical member 28 is simply slid by the slide switch 34. The configuration can be simplified and the cost can be reduced.

  In the first embodiment, the slide shaft 31 and the slide switch 34 are fixed by fitting the distal end of the insertion portion 34a into the insertion hole 31a formed at the distal end of the slide shaft 31. It is not limited to the case. For example, the slide shaft 31 and the insertion portion 34a of the slide switch 34 may be fixed using an adhesive. Alternatively, as shown in FIG. 8, a screw groove 31 b may be formed at the tip of the slide shaft 31 and a screw hole 34 c may be formed in the slide switch 34, and both may be fixed using a screw 37.

(Second Embodiment)
Next, a second embodiment according to the present invention will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the second embodiment and the first embodiment is that sound is output from the front air chamber R1 side in the first embodiment, but sound is also output from the rear air chamber R2 side in the second embodiment. It is the point which is comprised so that it can do.

That is, the electronic dictionary 40 of the present embodiment includes a speaker mechanism 41 in which a bass sound emission hole 42 is formed in the other cup-shaped member 27 as shown in FIG. The bass sound emission hole 42 is formed on the flat surface 27a of the other cup-shaped member 27 so as to communicate the rear air chamber R2 and the outside, and outputs the sound emitted from the speaker body 21 to the outside. It is like that.
Further, the top plate of the top cabinet 3b constituting the bottom case 3 of the present embodiment has a bass speaker hole (speaker hole) 43 communicating with the sound emission hole 42 at a position facing the sound emission hole 42 for the bus. The sound output from the sound output hole 42 for the bus is output to the outside of the bottom case 3.

  According to the electronic dictionary 40 configured as described above, when sound is output from the speaker main body 21 as shown in FIG. 10, it is echoed in the front air chamber R1 and the rear air chamber R2, and then released on the front air chamber R1 side. Sound can be output from the sound hole 23 and the sound output hole 42 for the bus on the rear air chamber R2 side. In particular, the sound emitted from the rear surface side of the speaker body 21 and reverberating in the rear air chamber R2 has a lower sound range than the sound emitted from the front surface side. That is, the sound in the low frequency range is mainly used. Therefore, this low-frequency sound can be output to the outside from the bass sound emission hole 42. Therefore, in addition to the sound output from the sound emitting hole 23 formed on the front air chamber R1 side, the sound in the low frequency range is actively sent from the bus speaker hole 43 through the bass sound emitting hole 42 to the bottom case 3. Can be output upward. As a result, the audio output balance can be changed more efficiently, and the audio output can be adjusted.

In the second embodiment, when the volume of the rear air chamber R2 is smaller than the volume of the front air chamber R1 and the volume difference between the two air chambers is larger than a predetermined value, for example (rear air chamber) When the volume of R2: the volume of the front air chamber R1) is (3: 7), (2: 8), (1: 9), etc., the bass sound emission hole 42 is configured to be blocked. good.
For example, as shown in FIG. 11, when the cylindrical member 28 is slid to the other cup-shaped member 27 side, the bass sound emission hole 42 may be blocked by the cylindrical member 28. In particular, when the volume of the rear air chamber R2 is sufficiently smaller than the volume of the front air chamber R1, the sound in the low frequency range cannot be sufficiently reflected in the rear air chamber R2, and the low frequency range. I can not expect so much audio output. Therefore, by physically blocking the bass sound emission hole 42, it is possible to prevent the sound from being output from the bass sound emission hole 42 unnecessarily.

In the second embodiment, the bass sound emitting hole 42 is formed on the flat surface 27a of the other cup-shaped member 27. However, as shown in FIG. 12, the bass speaker hole 43 is provided on the side surface of the top cabinet 3b. The bass sound emission hole 42 may be formed on the outer peripheral surface of the other cup-shaped member 27 other than the flat surface 27 a so as to communicate with the speaker hole 43.
By doing in this way, the sound output from the sound emission hole 23 on the front air chamber R1 side can be output toward the upper side of the bottom case 3, and from the sound emission hole 42 for the bus on the rear air chamber R2 side. The output low-frequency sound can be output toward the side of the bottom case 3. In other words, since the output direction of the sound can be changed, the sound can be heard with a different feeling.

The difference between the third embodiment and the first embodiment is that in the first embodiment, the sound is output toward the upper side of the bottom case 3, but in the third embodiment, the sound is output toward the side of the bottom case 3. It is the point which is comprised so that it can output.

  That is, as shown in FIGS. 13 and 14, the electronic dictionary 50 of this embodiment includes a speaker mechanism 51 in which a sound emitting hole 52 is formed on the end surface of one cup-shaped member 27.

As described above, the sound emission hole 52 is formed in the end surface of the one cup-shaped member 27. On the other hand, a speaker hole 53 communicating with the sound emission hole 52 is formed on the side surface of the top cabinet 3 b at a position facing the sound emission hole 52.

  According to the electronic dictionary 50 configured in this manner, the volume ratio between the front air chamber R1 and the rear air chamber R2 is changed by the slide operation of the slide switch 34, and the sound whose sound output balance is adjusted by this change is used as the bottom case. 3 can be output toward the side of 3. As described above, according to the electronic dictionary 50 of the present embodiment, only the sound output direction is different, and other functions and effects are the same as those of the first embodiment.

(Fourth embodiment)
Next, a fourth embodiment according to the present invention will be described with reference to FIGS. 15 and 16. In the fourth embodiment, the same components as those in the second embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the fourth embodiment and the second embodiment is that, in the second embodiment, sound is output toward the upper side of the bottom case 3, but in the fourth embodiment, in addition to the upper side of the bottom case 3, from the side. Is also configured to be able to output sound.

That is, the electronic dictionary 60 of the present embodiment includes a speaker mechanism 61 in which a sound emission hole 62 is further formed on the end surface of one cup-shaped member 27 as shown in FIGS. On the other hand, a speaker hole 63 communicating with the sound emission hole 62 is further formed on the side surface of the top cabinet 3 b at a position facing the sound emission hole 62.
According to the electronic dictionary 60 configured in this way, the sound output from the sound emission holes 23 and 62 on the front air chamber R1 side is directed upward and laterally of the bottom case 3 through the speaker holes 35 and 62. Can be put out. That is, since the voice output direction can be increased in two directions, the voice can be heard with a different feeling.

(Fifth embodiment)
Next, a fifth embodiment according to the present invention will be described with reference to FIGS. In the fifth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the fifth embodiment and the first embodiment is that the volume ratio of the front air chamber R1 and the rear air chamber R2 is changed by sliding the cylindrical member 28 in the first embodiment. In the fifth embodiment, the volume ratio between the front air chamber R1 and the rear air chamber R2 is changed by sliding the pair of cup-shaped members 27 respectively.

That is, as shown in FIGS. 17 to 19, the electronic dictionary 70 of the present embodiment includes a pair of cup-shaped members 27 that can slide and a cylindrical member 28 combined with the cup-shaped members 27. A speaker mechanism 71 having a storage body 72 is provided.
The pair of cup-shaped members 27 of the present embodiment has a flange 73 formed on the flat surface 27a, and is fixed in a state where the flange 73 is fitted in a slide groove 74 formed on the top plate of the top cabinet 3b. Yes. As a result, the pair of cup-shaped members 27 can be slidably moved in the direction of approaching and separating from each other (lateral width direction of the bottom case 3 (arrow A direction)) with the openings facing each other.

  In addition, slide shafts 31 are formed on the outer peripheral surfaces of the pair of cup-shaped members 27 toward the side surfaces of the top cabinet 3b. An insertion hole 31 a is formed at the tip of the slide shaft 31. On the other hand, two slide holes 32 and two slide grooves 33 are formed on the side surface of the top cabinet 3b of the present embodiment with a space therebetween. The slide switch 34 is fitted in the slide groove 33 in a state where the insertion portion 34 a is inserted through the slide hole 32. At this time, the insertion portion 34 a of the slide switch 34 is inserted into and fitted into the insertion hole 31 a of the slide shaft 31. Thereby, the slide switch 34 and the pair of cup-shaped members 27 are connected to each other.

  With this configuration, the pair of cup-like members 27 can be slid in the lateral width direction (arrow A direction) of the bottom case 3 by sliding the slide switch 34 along the slide groove 33. It can be done. In addition, the speaker hole 35 formed in the top plate of the top cabinet 3b is formed long in the horizontal width direction (arrow A direction), and even if one cup-shaped member 27 is slid and moved, It is designed to always communicate.

The cylindrical member 28 is combined with the cup-shaped member 27 with both ends inserted from the opening side of the pair of cup-shaped members 27, and is fixed to the top cabinet 3b by a support member (not shown). . Therefore, by sliding the slide switch 34, the pair of cup-shaped members 27 can be slid, and the position of the storage body 72 can be varied with respect to the speaker body 21.
That is, the positions of the storage body 72 and the speaker body 21 can be relatively varied. Thereby, the volume ratio between the front air chamber R1 and the rear air chamber R2 can be appropriately changed. Therefore, the slide switch 34 and the slide shaft 31 relatively change the positional relationship between the storage body 72 and the speaker main body 21 by sliding the pair of cup-shaped members 27, so that the front air chamber R1 and the rear air chamber It functions as a variable means 75 that changes the volume ratio with R2.

  When the sound output balance is changed by the electronic dictionary 70 configured as described above, the two slide switches 34 provided on the side surfaces of the top cabinet 3b constituting the bottom case 3 are appropriately slid. Thereby, a pair of cup-shaped member 27 can be slid and moved via the slide shaft 31, and the volume ratio of the front air chamber R1 and the rear air chamber R2 can be changed. Thereby, the reverberation state of the sound that reverberates in each of the front air chamber R1 and the rear air chamber R2 can be adjusted. As in the first embodiment, the sound quality, sound range and sound of the sound output from the speaker hole 35 can be adjusted. The sound output balance can be appropriately changed by changing the pressure or the like.

  As described above, in the present embodiment, only the point of sliding the pair of cup-shaped members 27 instead of the cylindrical member 28 is different from that of the first embodiment, and other functions and effects are the same as those of the first embodiment. . In the present embodiment, the volume ratio can be clearly changed with a simple configuration in which the pair of cup-shaped members 27 are simply slid by the slide switch 34, so that the configuration can be simplified and the cost can be reduced. Can lead to

(Sixth embodiment)
Next, a sixth embodiment according to the present invention will be described with reference to FIGS. In the sixth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The difference between the sixth embodiment and the first embodiment is that the volume ratio between the front air chamber R1 and the rear air chamber R2 is changed by sliding the slide switch 34 in the first embodiment. In the embodiment, the volume ratio between the front air chamber R1 and the rear air chamber R2 is changed by rotating the jog dial 84.

That is, in the electronic dictionary 80 of this embodiment, as shown in FIGS. 20 and 21, a speaker in which a storage body 82 is configured by a cup-shaped member 83 and a cylindrical member 85 whose one end is closed by a jog dial 84. A mechanism 81 is provided.
The cylindrical member 85 is formed in a cylindrical shape, and a disc-shaped jog dial 84 is integrally fixed to one end side. Therefore, the cylindrical member 85 can be rotated around the axis L by rotating the jog dial 84. The cylindrical member 85 is rotatably fixed to the bottom cabinet 3a constituting the bottom case 3. Moreover, a part of the jog dial 84 is exposed to the outside of the bottom case 3 and can be manually rotated from the outside. A male screw 85 a is formed on the outer peripheral surface of the cylindrical member 85.

  The cup-shaped member 83 is a cylindrical member having an internal thread 83a formed on the inner peripheral surface on the opening side, and is combined with the cylindrical member 85 in a state of being screwed into the male screw 85a. Therefore, the space surrounded by the cup-shaped member 83 and the cylindrical member 85 to which the jog dial 84 is fixed is a closed internal space for housing the speaker main body 21. The cup-shaped member 83 is supported by the bottom cabinet 3a in a state where the rotation is restricted by a rotation restricting member (not shown). Therefore, when the cylindrical member 85 is rotated by the rotation operation of the jog dial 84, the cup-shaped member 83 slides in the direction of the axis L.

In the cup-shaped member 83, the speaker main body 21 fixed to the ring-shaped support member 86 is housed. At this time, the support member 86 is slidably brought into contact with the inner peripheral surface of the cup-shaped member 83. The speaker body 21 is fixed to the support member 86 so that the front side faces the jog dial 84. Therefore, the space on the bottom surface side of the cup-shaped member 83 serves as the space on the rear surface side of the speaker body 21 and functions as the rear air chamber R2, and the space surrounded by the tubular member 85 is the space on the front surface side of the speaker body 21. And functions as the front air chamber R1.
Coil springs 87 are interposed between the support member 86 and the bottom surface of the cup-shaped member 83 and between the support member 86 and the end surface of the tubular member 85, respectively. That is, the support member 86 is housed in the cup-shaped member 83 in a state of being sandwiched between the two coil springs 87 from both sides.

With this configuration, when the jog dial 84 is rotated to slide the cup-shaped member 83 in the direction of the axis L, the amount of compression of the two coil springs 87 changes as appropriate. Therefore, the support member 86 sandwiched between the two coil springs 87 slides due to a change in the compression amount. Therefore, the position of the speaker body 21 can be varied with respect to the storage body 82, and the volume ratio between the front air chamber R1 and the rear air chamber R2 can be changed.
That is, the jog dial 84, the two coil springs 87, and the support member 86 relatively change the positional relationship between the storage body 82 and the speaker body 21, and change the volume ratio between the front air chamber R1 and the rear air chamber R2. It functions as the variable means 88.

  Further, a sound emitting hole 89 that communicates the front air chamber R1 and the outside is formed substantially at the center of the jog dial 84, and the sound emitted from the speaker body 21 is output to the outside. In the bottom cabinet 3 a, a sound passage 90 that connects the sound emission hole 89 and the speaker hole 35 is formed, and the sound output from the sound emission hole 89 is guided to the speaker hole 35. Thereby, it is possible to output the sound toward the upper side of the bottom case 3 through the speaker hole 35.

  When the sound output balance is adjusted by the electronic dictionary 80 configured as described above, the jog dial 84 provided on the side surface of the bottom case 3 is rotated. Then, the cylindrical member 85 rotates, and the cup-shaped member 83 tries to rotate following this. However, since the rotation of the cup-shaped member 83 is restricted by the rotation restricting member, the cup-like member 83 slides along the axis L direction. When the cup-shaped member 83 slides, the amount of compression of the two coil springs 87 changes as appropriate, so that the support member 86 sandwiched between the two coil springs 87 slides due to a change in compression balance. Thereby, the position of the speaker main body 21 can be changed, and the volume ratio of the front air chamber R1 and the rear air chamber R2 can be easily changed.

  As a result, it is possible to adjust the reverberation state of the sound that reverberates in each of the front air chamber R1 and the rear air chamber R2. Etc. can be changed to change the audio output balance appropriately. Therefore, even in the case of this embodiment, the same operational effects as those of the first embodiment can be obtained.

  In the present embodiment, the speaker hole 35 may be formed on the side surface of the bottom case 3, and the speaker hole 35 and the sound emission hole 89 may be communicated with each other through the sound passage 90. In this case, sound can be output from the side of the bottom case 3. Further, the speaker holes 35 may be formed on the upper surface and the side surfaces of the bottom case 3, respectively, and the audio passage 90 may be branched into two in the middle so as to communicate with both the speaker holes 35. In this case, audio can be output from the upper side and the side side of the bottom case 3, respectively.

(Seventh embodiment)
Next, a seventh embodiment according to the present invention will be described with reference to FIGS. In addition, in this 7th Embodiment, about the part same as the component in 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
The difference between the seventh embodiment and the first embodiment is that the volume ratio of the front air chamber R1 and the rear air chamber R2 is changed by sliding the speaker body 21 by operating the slide switch 34 in the first embodiment. However, in the seventh embodiment, the volume ratio between the front air chamber R1 and the rear air chamber R2 is changed by rotating the speaker body 21.

That is, the electronic dictionary 90 of the present embodiment includes a speaker mechanism 91 in which the speaker body 21 is rotatably provided as shown in FIGS.
The speaker main body 21 of the present embodiment is housed inside a top cabinet 3b constituting the bottom case 3 and a box-shaped housing body 92 that fits in the bottom cabinet 3a. A plate 93 having a through hole 93 a through which sound passes is housed inside the housing 92, and the speaker body 21 is fixed to the plate 93. At this time, the speaker body 21 is fixed so that the front side faces the upper side or the side of the bottom case 3.
One end of the plate 93 is rotatably fixed to two hinge portions 94 formed on the top plate of the storage body 92. Further, the other end side of the plate 93 is bent so as to slidably contact the inner surface of the storage body 92. Thereby, the closed internal space of the storage body 92 is divided into two by the plate 93, and functions as the front air chamber R1 and the rear air chamber R2.

The plate 93 is mechanically connected to a rotation mechanism 95 that can be manually operated from the outside of the bottom case 3, and can be rotated around a hinge portion 94. Thereby, the position of the speaker main body 21 can be varied with respect to the storage body 92, and the volume ratio of the front air chamber R1 and the rear air chamber R2 can be changed.
That is, the plate 93, the hinge part 94, and the rotation mechanism 95 change the volume ratio of the front air chamber R1 and the rear air chamber R2 by relatively changing the positional relationship between the storage body 92 and the speaker body 21. It functions as the variable means 96.

  In addition, a sound emitting hole 97 communicating with the front air chamber R1 is formed in the top plate of the storage body 92. The top plate of the top cabinet 3 b of the bottom case 3 is formed with a speaker hole 35 communicating with the sound emission hole 97 so that the output sound is output above the bottom case 3.

  When adjusting the audio output balance with the electronic dictionary 90 configured in this way, the rotation mechanism 95 is operated to rotate the plate 93 around the hinge portion 94. Then, since the speaker main body 21 rotates, the position of the speaker main body 21 can be changed with respect to the storage body 92, and the volume ratio of the front air chamber R1 and the rear air chamber R2 can be easily changed. As a result, it is possible to adjust the reverberation state of the sound that reverberates in each of the front air chamber R1 and the rear air chamber R2. Etc. can be changed to change the audio output balance appropriately. Therefore, even in the case of this embodiment, the same operational effects as those of the first embodiment can be obtained.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in each of the above embodiments, the portable electronic device has been described as an electronic dictionary. However, the electronic dictionary is not limited to an electronic dictionary, and is not particularly limited as long as it can output sound. For example, a portable information terminal such as a PDA or a mobile phone, a notebook personal computer, a music playback device, or the like may be used. In particular, the sound output balance can be changed efficiently by the speaker mechanism according to the present invention, which is effective when playing music, movies, and the like.

In each of the above-described embodiments, a description has been given by taking, as an example, a Stareo type electronic dictionary provided with two speaker mechanisms. However, the speaker mechanism may be a single monaural type.
Further, in each of the above embodiments, the variable means is manually operated to change the volume ratio between the front air chamber and the rear air chamber, but it is not necessary to be manually operated. For example, the positional relationship between the storage body and the speaker body may be relatively varied using a motor or the like operated by the control unit.

For example, taking the first embodiment as an example, the cylindrical member 28 is configured to be slidable by driving of a motor M as shown in FIG. As the motor M, a motor whose rotation direction and rotation amount can be freely adjusted may be used. That is, in this case, the motor M functions as a variable unit that varies the position of the speaker body 21 and changes the volume ratio between the front air chamber R1 and the rear air chamber R2.
One of the plurality of function switches 11 that is the input unit 12 is a switch that operates the motor M. And the control part 15 is provided with the operation signal control part 15a which outputs an operation signal to the motor M based on the input signal when this function switch 11 is pushed. At this time, the operation signal control unit 15a outputs a control signal so that the rotation direction and the rotation amount of the motor M change depending on the position where the function switch 11 is pressed, the pressed length, and the like. Then, the motor M operates based on the sent control signal, and automatically changes the volume ratio.

  With this configuration, the user can automatically perform the operation of the speaker main body 21 and the audio output adjustment by changing the audio output balance, simply by performing an input operation with the input unit 12. Therefore, the usability of the electronic dictionary 1 can be further improved.

  Further, in the case where the operation signal control unit 15a is provided, when the function switch 11 that activates the application is pressed, the optimal volume ratio for the application corresponding to the selected function switch 11 is calculated, and the calculated volume The operation signal control unit 15a may be caused to function so as to output a control signal to the motor M so as to have a ratio.

In such a configuration, when the user presses the function switch 11 to activate the application when listening to the native voice, the activation signal control unit 15a calculates the optimal volume ratio for the selected application. That is, the volume ratio between the rear air chamber R2 and the front air chamber R1 is calculated so that an optimal sound can be output for the selected country and sex. Then, the actuation signal control unit 15a outputs a control signal to the motor M so that the calculated volume ratio is obtained.
Then, the motor M slides the cylindrical member 28 based on this control signal, and makes it correspond to the calculated optimal volume ratio. As a result, the user can automatically listen to the native voice with the optimum voice output balance for the selected application. In other words, when listening to English with male voices or listening to Italian with female voices, it is possible to automatically listen with an optimal voice output balance depending on the situation. Therefore, the electronic dictionary 1 can be more easily used.
