  The TFT liquid crystal module 12, the first movable frame 13, and the second movable frame 14 are integrally bonded to each other by the bonding portions 26 a and 26 b, and constitute the touch panel portion 10. An adhesive is provided on the bonding portions 26a and 26b.

  The electronic device 1 includes a backlight 22, an intermediate frame 27, and a substrate 28. The backlight 22 is a light source that illuminates the TFT liquid crystal 19. The intermediate frame 27 fixes the substrate 28 with screws (not shown). The substrate 28 is mainly composed of a microcomputer having a CPU, RAM, ROM, I / O, etc. (not shown), and detects an operation position signal from the touch sensor 17, displays the TFT liquid crystal 19, vibrates by the actuator 24, In addition, various controls such as illumination of the backlight 22 are performed. In this way, the substrate 28 functions as a control unit.

  The TFT liquid crystal module 12 is disposed on the surface of the touch panel unit 10. The touch panel unit 10 includes a TFT liquid crystal module 12 and a first movable frame 13 and a second movable frame 14 bonded to the back surface of the TFT liquid crystal module 12. The first movable frame 13 and the second movable frame 14 have a substantially rectangular frame structure in which the central portion is a hollow window portion.

  The first movable frame 13 is made of a material having high rigidity and a low dielectric constant. The first movable frame 13 is, for example, a resin such as ABS (acrylonitrile, butadiene, styrene copolymer synthetic resin), PC (polycarbonate resin), PBT (polybutylene terephthalate resin), or the like, for example, glass or talc is added. It is made of a reinforcing material, glass, wood or the like. Moreover, the 1st movable frame 13 is comprised lightweight by using resin. The first movable frame 13 is fixed to the touch sensor 17 provided on the back surface of the TFT liquid crystal module 12 by adhesion or the like.

  The second movable frame 14 is configured using a highly rigid member. The second movable frame 14 is configured using, for example, a metal such as Fe, Al, Mg, or an alloy thereof, or, for example, carbon fiber. Further, as the second movable frame 14, a resin such as ABS, PC, PBT, or a reinforcing material thereof may be used. The second movable frame 14 is integrated with the first movable frame 13 by adhesion or insert.

  The electronic device 1 includes a movable yoke 23, a fixed yoke 11, and an actuator 24 fixed to the fixed yoke 11. In the embodiment, an example in which a solenoid type actuator 24 is used as the actuator 24 is shown. The actuator 24 includes an electromagnetic coil 24a in which a conductive wire is wound in a hollow coil shape, and a fixed iron core 24b disposed in a hollow portion of the electromagnetic coil 24a.

  The fixed yoke 11 is made of a material having a high magnetic permeability such as iron and has an effect of increasing the magnetic flux density when the actuator 24 is ON. The TFT liquid crystal module 12 is connected to the movable yoke 23 via the second movable frame 14 and the first movable frame 13. The movable yoke 23 and the second movable frame 14 are fixed by screws 15a.

  The TFT liquid crystal module 12, the first movable frame 13, and the second movable frame 14 are fixed by adhesive portions 26a and 26b. Accordingly, the touch panel unit 10 is configured by integrally bonding the TFT liquid crystal module 12, the first movable frame 13, and the second movable frame 14.

  A wiring portion 21 in which a wiring drawn out from the touch sensor 17 is arranged is provided at a peripheral edge portion 20 provided in a region along the outer periphery of the touch panel portion 10. A first movable frame 13 made of a low dielectric constant material is disposed at a position between the second movable frame 14 and the peripheral portion 20 and facing the peripheral portion 10.

  The movable yoke 23 is elastically held by a leaf spring 25 fixed to the fixed yoke 11. The fixed yoke 11 and the leaf spring 25 are screwed and fixed by screws 15b. The leaf spring 25 is fixed to the movable yoke 23 by means such as caulking. The movable yoke 23 and the touch panel unit 10 are integrally connected via the first movable frame 13 and the second movable frame 14. These are elastically supported by the leaf spring 25 as a whole.

  The movable yoke 23 is disposed at a position facing the fixed iron core 24b with a predetermined distance that can be attracted by the magnetic force generated by the electromagnetic coil 24a. The movable yoke 23 is made of a material having high magnetic permeability such as iron.

  When the electromagnetic coil 24a is energized, a magnetic force is generated in the fixed iron core 24b. As a result, the movable yoke 23 is attracted in the direction of the fixed iron core 24b, the leaf spring 25 is bent, and the movable yoke 23 is moved downward in the drawing. It is adsorbed and brought into contact with the iron core 24b. When the energization to the electromagnetic coil 24a is cut off, the attractive force in the direction of the fixed iron core 24b disappears, so that the movable yoke 23 moves away from the fixed iron core 24b by the elastic force of the leaf spring 25 and moves upward in the figure. Return to position. By repeating this movement, vertical vibration is generated. The actuator 24 functions as a vibration generating unit.

  What is vibrated by the actuator 24 is the touch panel unit 10, that is, the TFT liquid crystal module 12, the first movable frame 13, the second movable frame 14, and the movable yoke 23 for transmitting vibrations thereto. Hereinafter, the TFT liquid crystal module 12, the first movable frame 13, the second movable frame 14, and the movable yoke 23 are referred to as a movable portion 32.

  Since the movable portion 32 is integrally configured as a whole, the movable portion 32 moves together following the movement of the movable yoke 23. Accordingly, the vibration of the movable yoke 23 causes the movable unit 32 including the touch panel unit 10 to follow and vibrate. By detecting this vibration with a fingertip that contacts the touch panel unit 10, the user can display on the touch panel unit 10, for example. It can be recognized that the electronic device 1 has accepted the pressed switch.

  The TFT liquid crystal module 12 is integrally configured by laminating an overlay 16, a touch sensor 17, and a TFT liquid crystal 19. The overlay 16 is a decorative part on the front surface portion of the TFT liquid crystal module 12 and is a touch operation panel in which the touch sensor 17 is attached to the back surface side, that is, the TFT liquid crystal 19 side. The TFT liquid crystal 19 corresponds to a display for displaying switches and information for the user to operate.

  When the user touches the overlay 16 with a finger, the touch sensor 17 detects a touched position by detecting a change in capacitance value due to part of the lines of electric force absorbed by the touched finger. It corresponds to a position detector.

  The touch sensor 17 and the TFT liquid crystal 19 are bonded by an OCR 18 provided between them. The OCR 18 is an optical adhesive part for opto-carbonizing the touch sensor 17 and the TFT liquid crystal 19, and is a gel material capable of improving the visibility of a capacitive touch panel or display such as a smartphone or a tablet terminal. . In addition, it may replace with OCR18 and may use a sheet-like adhesive tape (OCA; Optical Clear Adhesive).

  A predetermined region at the end of the overlay 16 is a peripheral portion 20, and a display portion of the TFT liquid crystal 19 is not disposed in this portion. The peripheral portion 20 also serves as a wiring portion 21 in which a wiring for transmitting the amount of change in capacitance due to the touch of the touch panel portion 10 is arranged. Since the amount of electricity transmitted by the wiring portion 21 is extremely small, when an electric capacity is added to the wiring portion 21, the touch sensitivity with respect to the touch panel portion 10 is lowered.

  A metal second movable frame 14 is stacked in the stacking direction of the touch panel unit 10 via the first movable frame 13 made of a low dielectric material on the peripheral portion 20 where the wiring unit 21 is disposed. Has been. At this time, the 1st movable frame 13 and the 2nd movable frame 14 are arrange | positioned so that it may fit in the substantially width of the peripheral part 20. As shown in FIG.

  FIG. 4 is a view for explaining the arrangement of the actuator 24, and is a view of the inside of the electronic device 1 as viewed from the direction of the arrow in FIG. The actuator 24 is installed inside the holder 29. In FIG. 4, a frame line 10 a indicating the outer shape of the touch panel unit 10 is virtually shown.

  As shown in FIG. 4, the plurality of actuators 24, in the present embodiment, the four actuators 24, are positioned at four locations near the apex of the holder 29 configured in a substantially rectangular shape, that is, the touch panel unit 10. It is arranged to be located at the four corners. In this case, the actuator 24 is disposed at a position where it can be directly contacted with the second movable frame 14 or in the vicinity thereof, thereby efficiently giving vibration generated by the actuator 24 to the touch panel unit 10. Can do.

  5A and 5B schematically show the arrangement of the adhesive portions 26a and 26b. FIG. 5A is a view of the touch panel unit 10 as viewed from above, that is, a part of the touch panel unit 10 as viewed from the overlay 16 side. FIG. 5B is a longitudinal sectional view of the touch panel unit 10.

  As shown in FIGS. 5A and 5B, the touch sensor 17 disposed on the back surface of the overlay 16 and the first movable frame 13 are bonded by an adhesive portion 26a. The bonding portions 26a have a predetermined length, and a plurality of the bonding portions 26a are arranged so as to be spaced apart from each other.

  The 1st movable frame 13 and the 2nd movable frame 14 are adhere | attached by the adhesion part 26b. The bonding portions 26b have a predetermined length, and a plurality of the bonding portions 26b are arranged so as to be spaced apart from each other.

  The bonding portions 26a and the bonding portions 26b are arranged so as to be alternately arranged as viewed from the overlay 16 direction so as to be arranged at positions separated from each other. In a state where the touch panel unit 10 is assembled, the adhesive portions 26 a and 26 b are arranged on the front surface and the back surface of the first movable frame 13. That is, the bonding portion 26 a and the bonding portion 26 b are arranged so as to be alternately arranged on the front and back with respect to the first movable frame 13.

  The electronic device 1 according to the first embodiment described above has the following effects.

(Effect of dividing a plurality of actuators 24)
In the first embodiment, in the electronic apparatus 1, each actuator 24 is configured to be small and thin by disposing a plurality of actuators 24 (four in the first embodiment).

  When the output of the actuator 24 is large, the actuator 24 is configured to be large, and when the output is small, the actuator 24 is configured to be small. Therefore, when the movable part 32 is vibrated by one actuator 24, the large actuator 24 is used. In this case, it is necessary to arrange a transmission member for transmitting the vibration of the actuator 24 to the movable portion 32. Accordingly, the mass of the movable portion is increased by the amount of the transmission member, and vibration attenuation by the transmission member is added, so that the vibration efficiency of the movable portion 32 by the actuator 24 is lowered. In order to compensate for this, a larger actuator 24 is required.

  On the other hand, when the movable portion 32 is vibrated by a plurality of (here, four) actuators 24, a plurality of actuators 24 having a smaller output than the case where the single actuator 24 is vibrated may be provided. In this case, an actuator 24 having a size of about 1/4 may be used. Thereby, since the electronic device 1 which is small and thin can be configured, the electronic device 1 can be downsized.

  Further, if the electronic device 1 is configured using a plurality of actuators 24, the individual actuators 24 can be configured to be small and thin, and positions where vibration can be efficiently transmitted to the movable portion 32 without providing an additional vibration transmitting member or the like. That is, the actuator 24 can be arranged in the vicinity of the second movable frame 14 or a position where it can be directly contacted. Thereby, the efficiency of the vibration transmission generated by the actuator 24 can be improved, and the touch sensitivity can be improved.

(Effect of reducing the weight of the movable part 32)
In the first embodiment, since the first movable frame 13 is configured by using a resin such as ABS, the movable unit 32 is lighter and higher than the case where the movable unit 32 is entirely made of a metal material. It can be configured to be rigid. Thereby, since the mass vibrated by the actuator 24 becomes small, the touch panel part 10 can be vibrated efficiently. In addition, since the first movable frame 13 is configured using a highly rigid resin, vibration generated by the actuator 24 can be efficiently transmitted to the movable portion 32 without being attenuated.

(Effects of alternately arranging the adhesive portions 26a and 26b)
In the first embodiment, the arrangement of the bonding portions 26 a and 26 b for bonding the TFT liquid crystal module 12, the first movable frame 13, and the second movable frame 14 constituting the touch panel unit 10 to each other is the first movable frame 13. As seen from the front and back, they are arranged alternately. Thereby, the distance of the propagation path of the expansion-contraction difference produced between the TFT liquid crystal module 12, the 1st movable frame 13, and the 2nd movable frame 14 from which a linear expansion coefficient differs can be lengthened. Thereby, since transmission of stress applied to the TFT liquid crystal module 12 is relieved, it is possible to suppress the occurrence of display unevenness in the TFT liquid crystal, and it is difficult to cause adhesion peeling and the like. Can be provided.

(Effects by reducing capacitance at the peripheral edge 20)
Moreover, in 1st Embodiment, the 2nd movable frame 14 comprised with the metal is arrange | positioned through the 1st movable frame 13 comprised with the low dielectric material in the peripheral part 20 where the wiring part 21 is arrange | positioned. Has been. Thereby, since there is no substance having a high dielectric constant in the vicinity of the touch sensor 17, the absorption of electric lines of force in the touch sensor 17 can be suppressed. In addition, since a substance having a high dielectric constant does not exist at a position facing the wiring portion 21 of the peripheral edge portion 20, the capacitance of the wiring portion 21 can be reduced. Therefore, since the sensitivity of the capacitance change detected by the touch sensor 17 is improved, it is possible to improve the touch sensitivity of the user with respect to the touch panel unit 10, and thus the good vibration feeling when the user operates the touch panel unit 10. Make it possible to get.

(Effect of being able to be laminated within the width of the wiring part 21)
A first movable frame 13 made of a low dielectric material and a second movable frame 14 made of metal are stacked in the stacking direction of the touch panel unit 10 on the peripheral edge 20 where the wiring unit 21 is disposed. Yes. In this case, since the first movable frame 13 and the second movable frame 14 can be disposed within a substantially width of the peripheral edge portion 20, the peripheral edge portion 20 can be narrowed, and thus the electronic device 1 can be downsized.

  As described above, according to the first embodiment, by improving the efficiency of vibration transmission and improving touch sensitivity, it is possible to obtain a good vibration feeling when operating the touch panel unit, and An electronic device that can be miniaturized can be provided.

(Second Embodiment)
Next, a second embodiment will be described. 6A to 6F show variations in the arrangement of the actuator 24. FIG. 6A and 6B show an example in which two actuators 24 are arranged at the apexes at both ends of one side of the touch panel unit 10. 6C and 6D show an example in which the two actuators 24 are arranged at the center of the opposite sides of the touch panel unit 10. 6E shows an example in which four actuators 24 are arranged at the center of four sides constituting the touch panel unit 10, and FIG. 6F shows four apexes in which five actuators 24 constitute the touch panel unit 10.
