  FIG. 3 shows a cross-sectional view of the vehicle information providing apparatus 100 (third pointer type display unit 103) along the line AA in FIG. The configuration will be described in detail. The configuration of the first and second pointer type display units 101 and 102 is substantially the same as the configuration of the third pointer type display unit 103, and thus detailed description thereof is omitted.

  The third pointer type display unit 103 includes a circuit board 301, a driving device 303 that is conductively attached to the circuit board 301 and has a rotating shaft 302 extending forward, a pointer 304 that is rotationally driven by the rotating shaft 302, and the pointer An indicator plate 305 disposed behind the 304 and disposed on the circuit board 301, a turning member (covering member) 306 that defines a visible region of the indicator plate 305, and a front side of the turning member 306. The see-through panel 307 and a visor 308 that conceals the outer edge of the see-through panel 307 are configured.

  The circuit board 301 is made of, for example, a hard circuit board in which a wiring pattern (not shown) is provided on a glass epoxy base material, and includes a control means 202 that controls the auditory information providing means 220 and a drive that drives and controls the drive device 303. Unit 204, sound / speech synthesizer 221, amplifier 222, exciter 223, female connector 224 a for supplying drive signal to exciter 223, various circuit components such as resistors and capacitors ( (Not shown) is electrically connected to the wiring pattern. The female connector 224a is mounted on the back surface of the circuit board 301.

  The driving device 303 is composed of a movable magnet type instrument or a stepping motor, and the main part is mounted behind the circuit board 301 so that the rotating shaft 302 penetrates the circuit board 301, and by a suitable conducting means such as soldering. It is electrically connected to the wiring pattern (drive unit 204).

  The pointer 304 is made of a synthetic resin, and includes an instruction portion 304a that extends linearly so as to indicate an indicator portion (described later) of the indicator plate 305, and a cover (pointer cap) 304b that covers the center of rotation of the indicator portion 304a. ing.

  The indicator plate 305 is made of a synthetic resin such as PC and is formed in a substantially thin plate shape, and an indicator portion 305a made of scales, numbers, etc. indicated by the indicator portion 304a is formed on the surface thereof. In this case, the indicator portions 305 a are arranged in a substantially arc shape along the rotation trajectory of the pointer 304.

  The facing member 306 is made of, for example, black synthetic resin, and is disposed in front of the indicator plate 305. The pointer 304 and the opening 306a that exposes the indicator portion 305a of the indicator plate 305 to the user (driver), respectively, A support portion 306b having a substantially frame shape that extends toward the fluoroscopic panel 307 so as to surround the opening 306a and supports the fluoroscopic panel 307 is provided.

  The see-through panel 307 is made of a translucent synthetic resin, is formed in a substantially concave shape, and is supported (held) by the support portion 306b of the facing member 306 so as to cover the opening 306a of the facing member 306. The information displayed by the display unit D1 and the pointers and indicator plates of each pointer type display unit D2 are configured to be visible (transparent) to the user.

  And in this embodiment, when the vehicle information provision apparatus 100 is seen from the front (refer FIG. 1), the exciter 223 is being fixed to the back surface location of the fluoroscopic panel 307 directly under the 1st display part D1. Here, since the exciter 223 (the surface of the vibrating body) and the back surface of the fluoroscopic panel 307 are fixed (fixed) by using a sticking means such as a double-sided tape, the vibration according to the amplitude and phase of the electrical signal. The vertical vibration of the body is directly transmitted as bending vibration to the fluoroscopic panel 307.

  Further, between the see-through panel 307 and the substantially frame-like support portion 306b that supports the see-through panel 307, the support portion 306b is made of an elastically deformable (that is, flexible) material such as a cushion material or a spacer. By interposing the substantially frame-shaped buffer member 310 corresponding to the shape of the above, it is possible to prevent the bending vibration amount of the fluoroscopic panel 307 from being restricted due to the vertical vibration of the vibrating body.

  That is, the fluoroscopic panel 307 and the facing member 306 normally have a plurality of claw portions such as hooks provided at appropriate positions on the fluoroscopic panel 307 and the respective claw portions provided at appropriate positions on the facing member 306. Many configurations that are fitted and fixed with a plurality of locking portions are employed. However, in the configuration in which the claw portion and the locking portion are fitted, when the see-through panel 307 is bent and vibrated by the vertical vibration of the vibrating body, the bending vibration amount is restricted by the fitting (that is, the turning member 306). Therefore, in the present embodiment, a configuration in which the see-through panel 307 and the facing member 306 are indirectly joined via the buffer member 310 instead of the fitting is applied. Accordingly, in such an indirect joining configuration, the buffer member 310 is (elastically) deformed in conjunction with the flexural vibration of the fluoroscopic panel 307, so that the flexural vibration amount of the fluoroscopic panel 307 is not restricted by the turn-back member 306. A play (margin) can be given to the amount of flexural vibration of the panel 307.

  The visor 308 is made of, for example, black synthetic resin, is formed in a substantially cylindrical shape, and is disposed in front of the fluoroscopic panel 307 so as to hide only the outer edge portion of the fluoroscopic panel 307 that is a part of the fluoroscopic panel 307. The substantially cylindrical visor 308 is an internal space corresponding to the areas of the first display portion D1 and the pointer-type display portions D2 (the opening portion 306a region of the turning member 306) that the user can visually recognize through the perspective panel 307. The cavity 308a is provided. In other words, the visor 308 is disposed on the fluoroscopic panel 307 so that the outer edge portion surrounds the first display portion D1 and each pointer-type display portion D2, and the cavity portion 308a is caused by flexural vibration of the fluoroscopic panel 307. It has a function as a sound transmission part which transmits the generated sound to the user as a radiated sound.

  The above-described units constitute the vehicle information providing apparatus 100 (third pointer type display unit 103). The vehicle information providing apparatus 100 is connected to the travel control apparatus via the multiple communication line 230 as shown in FIG. 231 and the operating means 232.

  Next, the operation of the vehicle information providing apparatus 100 will be described. The control means 202 relates to the vehicle status, alarm information, and operation of the auto cruise and lane keep from the vehicle information terminal 210 and the multiplex communication input / output terminal 211 for inputting and outputting vehicle information. The information is obtained, and the vehicle status notification regarding the auto cruise and the lane keep, the alarm output, the guidance regarding the operation of the auto cruise and the lane keep, and the answer back are obtained through the exciter 223 of the auditory information providing unit 220 based on this information. Sound and voice (and the image of the first display unit D1) are used.

  Here, the operation at the time of input of the control means 202 will be described by taking the alarm information as an example. The control unit 202 obtains information about the vehicle from the vehicle information terminal 210 for inputting / outputting vehicle information and the multiplex communication input / output terminal 211, and determines whether there is a warning generation condition based on this information. Here, when the warning condition is detected, the warning information is notified by the sound information providing means 220 with the sound effect and the voice, and the display form related to the warning information is displayed by the first display unit D1.

  FIG. 4 shows a specific example, and the control means 202 inputs a detection signal indicating that the seat belt is not worn (not worn) via the vehicle information terminal 210 or the multiplex communication input / output terminal 211. Then, after the sound effect “Pawn”, the auditory information providing means 220 is controlled to output “Please wear your seat belt” by voice. Therefore, the vertical vibration of the vibrator in the exciter 223 of the auditory information providing unit 220 is transmitted to the fluoroscopic panel 307, and the sound effect and the sound are emitted from the fluoroscopic panel 307 toward the cavity 308a by the vibration of the fluoroscopic panel 307. Thus, the user can easily recognize the sound effect and the sound. Here, visual information is also used through the first display portion D1.

  As described above, in the present embodiment, the vehicle information providing apparatus 100 that notifies the user of predetermined information, the display unit D1 (D2) for displaying the predetermined information to the user, and the display A turn-back member 306 provided in front of the means D1 (D2) and having an opening 306a that exposes the display means D1 (D2), and the predetermined information can be seen through to the user through the opening 306a. A perspective panel 307 covering the opening 306a and an auditory information providing means 220 for providing the user with auditory information according to various states of the vehicle are provided, and the auditory information providing means 220 is arranged so as to contact the perspective panel 307. An exciter 223 that vibrates the fluoroscopic panel 307 in accordance with the auditory information, and is provided between the fluoroscopic panel 307 having the exciter 223 and the look-back member 306. The cushioning member 310 is made by interposing.

  Therefore, the user can perceive the sound generated by the bending vibration of the fluoroscopic panel 307 as if it were a sound (auditory information) emitted from the entire fluoroscopic panel 307. That is, since the vertical vibration of the vibrating body in the exciter 223 is directly transmitted to the fluoroscopic panel 307, the sound generated by the fluoroscopic panel 307 is given to the user as auditory information (for example, warning information) without being deteriorated. It is possible to provide an information providing apparatus for a vehicle having good acoustic characteristics. Further, since the see-through panel 307 is joined to the turn-back member 306 via the buffer member 310, sufficient play can be given to the flexural vibration of the see-through panel 307, thereby further improving the acoustic characteristics of the vehicle. An information providing apparatus can be provided.

  In the present embodiment, a visor 308 is provided in front of the fluoroscopic panel 307 so as to cover the outer edge of the fluoroscopic panel 307, and the visor 308 has a cavity 308a corresponding to the display means D1 (D2). Thus, the sound emitted from the see-through panel 307 due to the vertical vibration of the vibrating body in the exciter 223 is emitted as radiated sound into the cavity 308a. At this time, the see-through panel 307 and the visor 308 are formed. Since the concave space acts as a sound resonator, the radiated sound is as if the radiated sound was produced from the fluoroscopic panel 307 (inside the visor 308) as if it was a realistic sound (a sound with an increased volume feeling). Information can be transmitted to the user, thereby providing a vehicle information providing apparatus with good acoustic characteristics.

  In the present embodiment, the case where the single exciter 223 (the surface of the vibrating body) is fixed to the back surface of the fluoroscopic panel 307 has been described. However, for example, a plurality of exciters 223 (the surface of the vibrating body) are connected to the fluoroscopic panel 307. At least one or more may be fixed to any one of the surface, the back surface, or the surface, or a portion other than the back surface (for example, the side surface). For example, two exciters 223 may be fixed to the back surface of the fluoroscopic panel 307, two exciters 223 may be fixed to the front surface and the back surface of the fluoroscopic panel 307, or three exciters 223 may be fixed to the fluoroscopic panel. You may fix to the surface of 307, a back surface, and a side surface.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The same or corresponding parts as those in the first embodiment are denoted by the same reference numerals. Detailed description thereof is omitted. FIG. 5 shows an overview of an example of the vehicle information providing apparatus 400 according to the second embodiment, and FIG. 6 shows a cross-sectional view taken along the line BB in FIG. 5. This second embodiment is the first embodiment. The difference from the embodiment is that the first display unit D1 for displaying the vehicle speed or the like is formed by a first analog (pointer type) display unit 410 formed of a speedometer, not a liquid crystal panel or an organic EL panel. A substantially circular first opening 401a that defines the visible area of the first analog display 410, and a substantially circular second opening 401b that defines the visible area of the second analog display 420 comprising a tachometer. Each of the analog display units 410, 420, and 430 having a substantially circular third opening 401c that defines a visible region of the third and fourth analog display units 430 and 440 including a fuel meter and a thermometer. , 440 (Covering member) 401 is placed on each of the analog display units 410, 420, 430, 440, and the first, second, and third transparent panels 402, which are substantially disc-shaped in the openings 401a, 401b, 401c, The points 403 and 404 are fixed, and the exciter 223 is fixed to the first perspective panel 402. In the second embodiment, the illustration of the visor is omitted.

  Hereinafter, the configuration of the first analog display unit 410 will be described in detail. Since the other analog display units 420, 430, and 440 have substantially the same configuration as that of the first analog display unit 410, detailed description thereof is omitted. In the turn-back member 401 that is a component of the first analog display unit 410, the first transparent panel is disposed on the upper end side (the transparent panel 402 side) of the wall 401d surrounding the substantially circular first opening 401a. A substantially annular flange portion 401e that covers the outer edge portion of 402 is extended, and between the rear surface of the flange portion 401e and the outer edge portion of the first perspective panel 402, a substantially annular cushion material, a spacer, or the like. A buffer member 405 is interposed. In this case, since the buffer member 405 is disposed along the back surface of the flange 401e, the buffer member 405 is not directly visible to the user. The buffer member 405 and the flange portion 401e, and the buffer member 405 and the outer edge portion are both fixed by sticking means such as double-sided tape.

  An exciter 223 (the surface of the vibrating body) is fixed to a back portion of the first fluoroscopic panel 402 on the lower side of the center of the first analog display unit 410 by a sticking means such as a double-sided tape. Also in the second embodiment, the vibration body of the exciter 223 vibrates up and down according to the amplitude and phase of the electric signal, so that this vibration is directly transmitted to the first fluoroscopic panel 402. The user can perceive the sound generated by the flexural vibration of the first fluoroscopic panel 402 as if it were a sound (auditory information) emitted from the entire first fluoroscopic panel 402. Similar effects can be obtained.

  In the second embodiment, the exciter 223 is fixed only to one of the three perspective panels 402, 403, and 404, and the buffer member 405 is interposed between the perspective panel 402 and the facing member 401. Although the example has been described, an exciter may be individually fixed to any two of the fluoroscopic panels 402, 403, and 404, and a buffer member may be interposed between the two fluoroscopic panels and the facing member. Alternatively, exciters may be individually fixed to all the three fluoroscopic panels, and buffer members may be interposed between the three fluoroscopic panels and the facing member, and in particular, left and right (both sides of the first fluoroscopic panel 402). Exciters are respectively fixed to the rear surfaces of the second and third fluoroscopic panels 403 and 404 positioned at Cushioning member if brought into each interposed, it is possible to improve the separation characteristics of the sound emitted individually from each perspective panels 403 and 404 (e.g., warning information).

  For example, a first notification unit (not shown) for notifying the user that the seat belt is not worn is provided in the visible region (second analog display unit 420) of the second perspective panel 403, and the third perspective panel. A second notification unit (not shown) for notifying the user that the remaining amount of fuel is equal to or less than a predetermined amount is provided in the visible region 404 (third analog display units 430 and 440), and the seat belt is not worn. When the first notification unit is turned on, the exciter is driven at the same time as the first notification unit is turned on, and the sound effect “Pawn” is applied from the entire second fluoroscopic panel 403 in the same manner as in the first embodiment. If the remaining amount of fuel is less than or equal to a predetermined amount, the third fluoroscope is activated by driving the exciter simultaneously with the lighting of the second notification unit. Entire panel 404 For example, after the sound effect “Pom Pawn” is configured so that the warning information “please refuel” is output independently by voice, the user can see these sound effects and sound individually. Since it can be heard as an independent sound through the panel, it is possible to provide an information providing device for a vehicle with good sound separation characteristics.

  In the second embodiment, an example in which a double-sided tape or the like is attached to the front and back of the substantially annular buffer member 405 and the buffer member 405 with the double-sided tape is looked back and interposed between the member 401 and the fluoroscopic panel 402 is described. As described above, for example, the double-sided tape is not applied to the buffer member 405, but an annular groove for fixing the outer edge portion of the substantially disc-shaped transparent panel 402 is applied to the inner wall surface of the substantially circular buffer member 405. The buffer member 405 having the see-through panel 402 fixed to the annular groove has three or more protrusions (for example, the above-described protrusions 401e and 401e extending inward from the inner wall surface of the wall 401d with a predetermined interval between the flange 401e and the flange 401e. You may employ | adopt the structure pinched | interposed with four protrusion pieces formed at equal intervals along an inner wall surface.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIGS. 7 and 8. The same or corresponding parts as those in the first embodiment described above are denoted by the same reference numerals. Detailed description thereof is omitted. FIG. 7 shows an overview of an example of the vehicle information providing apparatus 500 according to the third embodiment, and FIG. 8 shows a cross-sectional view taken along the line CC in FIG. 7. This third embodiment is the first embodiment. The difference from the embodiment is that the first display portion D1 for displaying the vehicle speed or the like is formed by a pointer-type display portion 510 made of a speedometer, not a liquid crystal panel or an organic EL panel, and the rear surface of the fluoroscopic panel 307 is substantially at the center. In FIG. 7, a thin portion 307a made of a line-shaped groove (concave portion) is provided along the vertical direction (direction perpendicular to the longitudinal direction of the perspective panel 307) in FIG. 7, and the perspective panel 307 borders the thin portion 307a. The first see-through part 307b located on the left side of the thin part 307a and the second see-through part 307c located on the right side of the thin part 307a are divided, and the see-through parts 307b thus divided equally 307 It lies in that abut individually exciter 223a, 223b to the. In the third embodiment, the illustration of the visor is omitted.

  For example, the first notification unit for notifying the seat belt non-wearing employed in the second embodiment is arranged on the first pointer-type display unit (rotometer) 101 that becomes the visible region of the first see-through unit 307b. In addition, the second notification unit is provided to notify the fuel refueling employed in the second embodiment on the second pointer-type display unit (fuel gauge) 102 that becomes the visible region of the second see-through unit 307c. When the seat belt is not worn, when the first notification unit is turned on, the exciter 223a fixed to the first see-through unit 307b is driven at the same time as, for example, the sound effect “Pawn” from the entire first see-through unit 307b. ", The warning information" Please wear your seat belt "is output by voice. Further, when the remaining amount of fuel is equal to or less than a predetermined amount, for example, the sound effect “Pompon” is generated from the entire second fluoroscopic part 307c by driving the exciter 223b fixed to the second fluoroscopic part 307c simultaneously with the lighting of the second notification part.

  At this time, since the first see-through portion 307b and the second see-through portion 307c are connected via the thin portion 307a, the first see-through portion 307a bends and vibrates due to the vertical vibration of the vibrating body in the exciter 223a. The vibration of the see-through portion 307b is not easily transmitted to the adjacent second see-through portion 307c side, and the vibration of the second see-through portion 307c that similarly bends and vibrates due to the vertical vibration of the vibrating body in the exciter 223b. Since it is difficult for the user to hear these sound effects and sounds as independent sounds through the individual fluoroscopic parts, it is possible to provide vehicle information with good sound separation characteristics. An apparatus can be provided. Also in the third embodiment, since the see-through panel 307 is joined to the look-back member 306 via the buffer member 310, sufficient play can be given to the bending vibration of the see-through portions 307b and 307c. Therefore, the same effect as the first embodiment can be obtained.

  In the third embodiment, the example in which the see-through panel 307 is divided so as to have the two see-through portions 307b and 307c by the thin-walled portion 307a made of a line-shaped groove has been described. However, the thin-walled portion 307a It is also possible to provide a plurality of parts on the rear surface of the transparent panel 307, for example, by forming a substantially cross-shaped thin part on the rear surface of the transparent panel 307, and partitioning the transparent panel 307 to have four transparent parts. The exciter may be fixed to a necessary fluoroscopic part among the four fluoroscopic parts. This means that there may be a see-through portion where the exciter is not fixed among the four see-through portions.

  In each of the above embodiments, the case where the exciter (the surface of the vibrating body) is brought into contact with the rear surface of the fluoroscopic panel to vibrate the fluoroscopic panel (the fluoroscopic part) is described. However, the exciter (the surface of the vibrating body) vibrates the fluoroscopic panel. If possible, the surface of the vibrating body can be brought into contact with an arbitrary part of the fluoroscopic panel. For example, the surface of the vibrating body may be a surface (front surface) of the fluoroscopic panel, or a portion other than the surface and the back surface (for example, It is good also as a structure made to contact | abut to a side surface. It should be noted that at least a part of the vibrating body surface and the transparent panel (the front surface, the back surface, the side surface, etc.) may be in contact (contact).

  In each of the embodiments, the connection member 224 (female connector 224a and male connector 224b) including a pair of connectors for connecting the exciter 223 (223a, 223b) and the amplifier 222 is provided on the back side of the circuit board 301. In the case where the circuit board 301 is mounted, for example, when the longitudinal shape of the circuit board 301 is further increased along the longitudinal direction with respect to the shape described in FIGS. 224 can be mounted on the front side of the circuit board 301.
