Description

  The present invention relates to an electronic device. More specifically, the present invention relates to an electronic device that detects an operation input to a touch panel and feeds back an operational feeling, and a method of manufacturing the electronic device.

  Currently, touch panels and touch pads are widely used as input devices for electronic devices. In such an input device, when an operator operates a touch panel, a touch pad, or the like, a device that feeds back a feeling of operation to an operator's fingertip by vibrating the touch panel or the touch pad is proposed ( For example, see Patent Document 1).

  FIG. 8 is an external perspective view in which the electronic device described in Patent Document 1 is disassembled. As shown in FIG. 8, the electronic device (display device) described in Patent Document 1 includes a display monitor 100, a panel fixing frame 210, a touch panel 400, and a cover 500. This electronic device is configured by assembling each component such as the touch panel 400 to the display monitor 100.

  In the electronic device described in Patent Document 1, the display monitor 100 is composed of a liquid crystal display (LCD), and has a rectangular and flat shape as a whole. The display monitor 100 displays, for example, objects such as keys and buttons or various information on the display surface according to control by a control device (not shown). On the display surface of the display monitor 100, the touch panel 400 having the same size as that of the monitor 100 is assembled.

  The touch panel 400 is configured so that, for example, when a matrix-like switch circuit is formed on a transparent resin plate and the panel surface is touched by an operator's fingertip or the like, a detection signal corresponding to the contact position is output to the control device. It is configured. That is, the operator can input various information corresponding to the display to the electronic device by operating the panel 400 according to the display on the display monitor 100 displayed through the touch panel 400.

  In this electronic device, as shown in FIG. 8, a pair of piezoelectric elements (piezo elements) 420 are attached along the upper side (the back side in the figure) and the bottom side (the near side in the figure) of the back surface side of the touch panel 400. It has been. When the touch panel 400 detects contact by the operator, the electronic device gives a drive signal (voltage) to the piezoelectric element 420 from the control device. When this drive signal is received, the piezoelectric element 420 expands and contracts to deform (bend) the touch panel 400, so that the electronic device can generate vibration on the operation surface of the touch panel 400. That is, the touch panel 400 vibrates with the above operation, so that the operator can obtain an operational feeling.

  In this electronic apparatus, the touch panel 400 is assembled to the display monitor 100 via a panel fixing frame 210. The panel fixing frame 210 is formed of a hard resin material such as ABS, so that the entire panel fixing frame 210 has rigidity.

  As shown in FIG. 8, a holder 220 that holds the touch panel 400 at its four corners is assembled to the panel fixing frame 210. FIG. 9 is an enlarged view showing a state where one of the four holders 220 is attached to a corner of the touch panel 400. Each holder 220 is formed with a slit-like insertion portion 360 into which a corner portion of the touch panel 400 can be inserted. As shown in FIG. 8, a fixing hole 320 for fixing the holder 220 is provided on the peripheral side surface of the panel fixing frame 210 near the end of each side surface. 9 is inserted into each fixing hole 320 shown in FIG. 8, each holder 220 fixes the touch panel 400 to the panel fixing frame 210.

  As described above, when the four corners of the touch panel 400 are inserted into the respective holders 220, the respective holders 220 hold the touch panel 400 from the outside at the four corners and also from both sides in the thickness direction. Therefore, the electronic device described in Patent Document 1 can be arranged such that the touch panel 400 is fixed.

  Each of the holders 220 is made of a material having a smaller elastic coefficient than that of the panel fixing frame 210, and is integrally formed of, for example, a silicone-based resin or rubber. As described above, the holder 220 is configured to be elastically deformable so that the touch panel 400 can vibrate while stably holding the touch panel 400. Note that a gap that allows displacement of the touch panel 400 in the thickness direction is secured between the touch panel 400 and the display monitor 100. For this reason, when the piezoelectric element 420 vibrates, the displacement of the touch panel 400 in the thickness direction accompanying the vibration is possible.

  Therefore, the electronic device described in Patent Document 1 partially supports the outer edge portion of the touch panel 400 so that the vibration is not greatly hindered. it can.

JP 2010-44497 A

  As described above, the electronic device described in Patent Literature 1 can ensure a feeling of operation due to vibration of the touch panel, and can be arranged so that the touch panel is fixed.

  By the way, the electronic device described in Patent Document 1 is assumed to be, for example, a display device of an in-vehicle navigation system, and no measures against dust and water are taken on the electronic device itself. For example, when the electronic device shown in FIG. 8 is assembled, the touch panel 400 is attached to the panel fixing frame 210 while being inserted into the insertion portion 360 of the elastic material holder 220, that is, via the holder 220. This is because if the touch panel 400 is firmly fixed to the panel fixing frame 210 over the entire circumference, the touch panel 400 is not displaced in the thickness direction when the piezoelectric element 420 vibrates, and the touch panel 400 vibrates well. It is because it becomes impossible to make it. Therefore, a gap is formed between the touch panel 400 and the panel fixing frame 210, and it is assumed that dust and moisture enter from the gap.

  Therefore, in the electronic device described in Patent Document 1, as a dust-proof measure, for example, a member such as a dust-proof cushion may be inserted between the touch panel 400 and the panel fixing frame 210. However, even if such a dustproof cushion is made of a material that can be compressed to some extent, it takes up a physical space where the touch panel bends by the thickness after compression. Therefore, in such a structure, there arises a problem that the amplitude when the touch panel vibrates cannot be obtained.

  Further, when waterproofing the electronic device disclosed in Patent Document 1, in order to prevent entry of dust and water from the outside, for example, waterproofing is performed between the touch panel 400 and a member covering the periphery of the touch panel 400. A measure to fix with tape is conceivable. For example, as shown in FIG. 8, when the cover 500 is further attached to the combination of the touch panel 400 and the display monitor 100 via the panel fixing frame 210, the cover 500 and the touch panel 400 are fixed with waterproof tape. be able to. In this way, if the cover 500 and the touch panel 400 are fixed with waterproof tape over the entire circumference, the gap between the cover 500 and the touch panel 400 can be filled, so that the ingress of water from the outside can be prevented. Can do.

  However, if the cover 500 and the touch panel 400 are fixed with a waterproof tape over the entire circumference in this way, the amplitude when the touch panel 400 vibrates cannot be obtained. Thus, when a waterproof measure is applied to the touch panel device, there is a problem that the amplitude when the touch panel is vibrated at the same time is reduced.

  Furthermore, in the electronic device described in Patent Document 1, only the holders 220 at the four corners fix the touch panel 400 to the panel fixing frame 210. Further, as described above, the holder 220 is made of an elastic material such as silicone resin or rubber. For this reason, in the electronic device, when a strong impact is applied from the outside, for example, when the electronic device is dropped on the floor, the portion fixed by the holder 220 (for example, the insertion portion 360) cannot withstand the impact, and the touch panel 400 is removed from the holder 220. Inconveniences such as coming off and peeling off are assumed.

  As shown in FIG. 8, when the cover 500 is further attached after the touch panel 400 is assembled, even if the touch panel 400 is detached from the holder 220, the touch panel 400 may not be dropped through the cover 500. Seem. However, even in such a configuration, when the touch panel 400 is detached from the holder 220, that is, when the touch panel 400 is peeled off, inconveniences such as the touch panel 400 being displaced or wobbling inside the cover 500 are unavoidable. In addition, as described above, for example, if the touch panel 400 and the cover 500 are firmly fixed in order to prevent the touch panel 400 from being peeled off, the touch panel 400 becomes difficult to bend, and thus the amplitude when the touch panel 400 is vibrated. There is a problem of diminishing.

  Accordingly, an object of the present invention is to provide an electronic device capable of gaining sufficient amplitude while taking measures for waterproofing and dust-proofing in an electronic device in which a touch panel is bent and vibrated by a piezoelectric element or the like, and a method for manufacturing the electronic device. To do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an entire electronic apparatus according to an embodiment of the present invention. The electronic device 1 according to the present embodiment includes an upper housing 11, a lower housing 12, and a touch panel 21 in appearance. The touch panel 21 will be described later.

  The upper casing 11 and the lower casing 12 constitute the casing 10 by combining them together. Between the upper housing 11 and the lower housing 12, in the state where they are integrally combined, although not shown in the drawing, for example, a suitable waterproof structure is achieved by, for example, a sealed structure via rubber packing. And dust-proof measures are taken. The upper housing 11 and the lower housing 12 are preferably made of a material that can withstand a certain degree of impact, such as a resin case. In the following description, detailed description of the combined structure of the upper housing 11 and the lower housing 12 is omitted.

  2 is a plan view of the electronic device 1 shown in FIG. 1 with the upper housing 11 removed, and FIG. 3A is a cross-sectional view taken along the line AA in FIG. It is a figure which shows the state by which the heat contraction member was filled into the through-hole of this. As illustrated, the touch panel 21 is supported by the lower housing 12 via the elastic member 30. Here, an adhesive member 41 is provided on each of the front and back surfaces of the elastic member 30, and the touch panel 21, the elastic member 30, and the lower housing 12 are coupled by the adhesive member 41.

  In the present embodiment, the touch panel 21 is formed of, for example, a transparent resin material. In the example shown in FIG. 2, the touch panel 21 has a rectangular shape, but may have a square shape. In this specification, “rectangular shape” and “square shape” include not only a case where each side is a straight line but also a case where it is an arc.

  In the present embodiment, as shown in FIG. 2, the two vibrating portions 22 extend substantially in parallel in the direction along the edge 21 b on the short side in the vicinity of the short side of the touch panel 21. For example, it is fixed to the back surface of the touch panel 21 with a double-sided tape, an adhesive, or the like.

  The vibration unit 22 presents a tactile sensation to a contact object that is in contact with the operation area 21a of the touch panel 21 by generating vibration according to a predetermined vibration pattern. In the present embodiment, the vibration unit 22 is, for example, a piezoelectric element, and is expanded and contracted in the longitudinal direction based on, for example, a drive signal supplied from a control unit on the circuit board 50 illustrated in FIG. . Thereby, the vibration part 22 can bend and vibrate the touch panel 21 in the direction shown by the arrow in FIG. 1, that is, the direction in which the short side is bent more greatly than the long side.

  The touch panel 21 is disposed on the front surface of the display unit 60 illustrated in FIG. 3, for example, and touches an object displayed on the display unit 60 with an operator's finger, a stylus pen, or the like (hereinafter simply referred to as “contact object”). Is detected in the operation area 21a of the corresponding touch panel 21. Therefore, in the present embodiment, the “touch panel” will be described assuming a member disposed on the front surface of the display unit 60 that can be an LCD or the like, that is, a member provided separately from the display unit 60. In addition, the touch panel 21 detects the contact position of the contact object with respect to the operation region 21a, and notifies the detected position of the contact to the control unit on the circuit board 50 described above, for example.

  As the touch panel 21, for example, a touch panel configured by a resistance film method, a capacitance method, an optical method, or the like can be used. In addition, for the touch panel 21 to detect contact with a contact object, it is not essential that the contact object physically touch the touch panel 21. For example, when the touch panel 21 is an optical type, the touch panel 21 detects a position where infrared rays on the touch panel 21 are blocked by the contact object, and thus it is not necessary for the contact object to touch the touch panel 21.

  The display unit 60 described above displays an object such as a push button switch (push button switch) such as a key as an image. This object is an image that suggests to the operator an area to be touched on the operation area 21 a of the touch panel 21. The push button switch is a button, key, or the like (hereinafter, simply referred to as “key, etc.”) used by an operator for input operation. The display unit 60 is configured using, for example, a liquid crystal display panel (LCD), an organic EL display panel, or the like. In the present specification, detailed description of display-related matters is omitted.

  Further, as illustrated in FIG. 4, the elastic member 30 has a frame shape that has substantially the same outer shape as the touch panel 21, and a plurality of through holes 30 a that penetrate the front and back surfaces of the elastic member 30 are provided on each side of the frame. Is provided. In the illustrated example, the through hole 30a is rectangular, but it may be circular or elliptical, and the shape can be selected as appropriate. In the illustrated example, three through holes 30a are provided along the short-side edge 21b of the touch panel 21 and four through-holes 30c are provided along the long-side edge 21c. It can be selected as appropriate. The elastic member 30 is required to have a certain degree of elasticity without penetrating water. Examples of such a member include silicone rubber.

  Further, in the example shown in FIGS. 2 and 3A, the heat shrinkable member 31 is filled in each through hole 30 a of the elastic member 30. In the present specification, the term “heat-shrinkable member” means a member that has a physical property that shrinks when heat is applied and has a volume after heating that is less than the volume before heating. Such as, for example, radiation-crosslinked polyolefin, radiation-crosslinked vinylidene, radiation-crosslinked flexible fluorinated polymer, radiation-crosslinked fluorinated elastomer, radiation-crosslinked elastomer, two-layer structure radiation-crosslinked polyolefin, electron beam-crosslinked polyolefin, elastic neoprene, Examples include fluoroplastic Teflon and polytetrafluoroethylene.

  As shown in FIG. 5, the adhesive member 41 has a frame shape that is substantially the same shape as the elastic member 30. The adhesive member 41 is a waterproof double-sided adhesive member, such as a waterproof tape, and examples thereof include Sekisui Chemical Co., Ltd. foam tape (# 5202WP). Here, when the adhesive member 41 is attached to the elastic member 30 in which nothing is filled in the through-hole 30a, the adhesive member 41 enters the through-hole 30a, or the adhesive members 41 that have entered are adhered to each other. There is an increased risk of wrinkles. For this reason, there is a concern that the touch panel 21 and the elastic member 30 cannot be sufficiently bonded to each other, so that necessary adhesive strength cannot be obtained, or water enters from the gap between the bonding members 41. In the present embodiment, by adhering the adhesive member 41 in a state where the heat shrinkable member 31 is filled in the through hole 30a, entry of the adhesive member 41 into the through hole 30a and generation of wrinkles of the adhesive member 41 are suppressed. Is done. Thereby, since the touch panel 21, the elastic member 30, and the lower housing | casing 12 can be sealed over those perimeters, the closure formed by the touch panel 21, the elastic member 30, and the lower housing | casing 12 is carried out. It is possible to prevent water from entering the space S and dust from entering. Moreover, since the touch panel 21 is combined over the entire circumference, the possibility that the touch panel 21 is peeled from the electronic device 1 can be sufficiently eliminated.

  The electronic apparatus 1 according to the present embodiment configured as described above has the heating environment after the elastic member 30, the touch panel 21, and the lower housing 12 filled with the heat shrinkable member 31 are coupled by the adhesive member 41. The heat contraction member 31 in the through hole 30a is contracted below. As a result, as shown in FIG. 3B, a gap is formed in the through hole 30a, and the outer peripheral portion of the touch panel 21 can be partially supported by the elastic member 30. Can earn. The heating conditions are selected according to the physical properties of the heat shrinkable member 31.

  Next, another embodiment of the present invention will be described with reference to the drawings.

  6 is a plan view of the electronic apparatus 1 shown in FIG. 1 with the upper housing 11 removed, and FIG. 7A is a cross-sectional view taken along line BB in FIG. It is a figure which shows the state filled with the sublimation member instead of the heat contraction member with which the through-hole of this is filled. In addition, in another embodiment of the present invention, the heat shrinkable member 31 is replaced with the sublimation member 32 and the adhesive member 41 is replaced with the adhesive member 42 with respect to the above-described embodiment. Since they are common, the description is omitted.

  As shown in FIGS. 6 and 7A, the sublimation member 32 is filled in each through hole 30 a of the elastic member 30. In this specification, the “sublimation member” means a member having physical properties that change (sublimate) from a solid to a gas. Examples of such materials include dry ice, iodine, naphthalene, oxalic acid, paradichlorobenzene, salicylic acid, terephthalic acid, and the like.

  As shown in FIG. 5, the adhesive member 42 has a frame shape that is substantially the same shape as the elastic member 30. The adhesive member 42 is a double-sided adhesive member having waterproofness and gas permeability, for example, a waterproof tape. The above-mentioned foam tape (# 5202WP) of Sekisui Chemical Co., Ltd. has gas permeability to various substances in addition to waterproofness, so it should be used in other embodiments of the present invention. Can do. The gas permeability of the adhesive member 42 is selected so as to allow the sublimation member 32 to pass therethrough according to the sublimation member 32 employed. Similarly to the adhesive member 41 described above, the adhesive member 42 can also prevent the penetration of the through-hole 30a and the generation of wrinkles, so that the possibility of peeling of the touch panel 21 can be sufficiently eliminated, and the circuit board 50 and the display unit 60 can be eliminated. A sufficient dustproof and waterproof effect can be obtained.

  In the electronic device 1 according to another embodiment of the present invention configured as described above, after the elastic member 30 filled with the sublimation member 32, the touch panel 21, and the lower housing 12 are coupled by the adhesive member 42. Then, the sublimation member 32 in the through hole 30a is sublimated in a sublimation environment, and is released to the outside through the adhesive member. Here, the sublimation environment means that at least one of the pressure and the temperature is changed in accordance with the condition under which the selected sublimation member 32 is sublimated. As a result, the solid sublimation member 32 does not remain in the through hole 30a as shown in FIG. 7B, and the outer peripheral portion of the touch panel 21 can be partially supported by the elastic member 30, so that the bending vibration In this case, a sufficient amplitude can be obtained.

  In addition, this invention is not limited only to the said embodiment, Many deformation | transformation or a change is possible. For example, the number of vibration units 22 is not limited to two, and can be any number according to the amplitude of the required bending vibration.

Further, what is filled in the through hole 30a is not limited to the heat shrinkable member 31 and the sublimation member 32 described above, but the volume decreases when the phase transitions from a solid to a liquid, and the electronic device 1 is normally used at room temperature. In this case, a substance that maintains a liquid state (for example, water) can be used. In addition to the volume at the time of filling, there are various types in which the volume remains reduced at room temperature due to changes in environmental conditions (temperature, pressure, etc.) and changes over time (for example, substances that change with standing within a few days). A substance can be selected.

  In the present embodiment, the above-described lower housing 12 constitutes a “support member”, and the support member does not include a display portion such as a display, a substrate constituting a control portion, or the like. Explained as a thing. However, in the present invention, the “support member” is not limited to the lower housing 12, and various members such as the display unit 60 and the circuit board 50 can be used as the support members.

  In addition, the present invention is characterized by the elastic member 30, the heat shrink member 31, the sublimation member 32, and the adhesive members 41 and 42, and the other constituent elements other than those described in the present specification. Also, various configurations can be adopted. For example, in each embodiment mentioned above, the aspect which displays an object on the display part 60 arrange | positioned on the back side of the touch panel 21, and the touch panel 21 detects an operator's contact was demonstrated. However, the present invention is not limited to such an aspect. For example, it is assumed that an object is directly printed with ink or the like on the operation area 21a of the touch panel without the display unit 60. You can also.

  And in the said embodiment, the contact with respect to the operation area | region 21a of the said touch panel 21 was detected using the touch panel 21. FIG. That is, in the above embodiment, the “touch panel 21” has been described assuming a member such as a so-called touch sensor. However, the touch panel used in the electronic device according to the present invention may be any as long as it can be touched by a contact object such as an operator's finger or a stylus pen.

  For example, the touch panel 21 used in the electronic apparatus according to the present invention may be a member such as a simple “panel” that does not detect the position of contact of the contact object with the operation region 21a (that is, does not have a sensing function). In the electronic device having such a configuration, for example, by further providing a pressure detection unit that detects a pressure on the operation region 21a, it is determined that a touch on the touch panel has been made based on the pressure detected by the pressure detection unit. be able to.

  Moreover, in the said embodiment, the contact with respect to the operation area | region 21a of the said touch panel was detected using the touch panel. However, it is also possible to determine that the touch detection unit detects a press on the touch panel and that the touch is made on the touch panel based on the press.

  The above-described press detection unit detects a press on the operation area of the touch panel. For example, a strain gauge sensor or a piezoelectric that changes physical or electrical characteristics (strain, resistance, voltage, etc.) according to the press. An arbitrary number of elements can be used. Further, when the vibration unit is a piezoelectric element, the piezoelectric element can also be used as a press detection unit. By adopting such a configuration and detecting the distortion of the touch panel due to the press, it is possible to assume a configuration in which the pressure on the touch panel is calculated from the distortion.

  For example, when the press detection unit is configured using a piezoelectric element or the like, the piezoelectric element of the press detection unit is a load (force) magnitude (or a load (force) magnitude related to the press on the operation area of the touch panel. The voltage magnitude (voltage value), which is an electrical characteristic, changes according to the speed (acceleration) at which the voltage changes. In this case, the pressure detection unit can notify the control unit of the magnitude of the voltage (voltage value (hereinafter simply referred to as data)). The control unit acquires the data when the press detection unit notifies the control unit of the data, or when the control unit detects data related to the piezoelectric element of the press detection unit. That is, a control part acquires the data based on the press with respect to the operation area | region of a touch panel. That is, a control part acquires the data based on a press from a press detection part. Then, when the data based on the press satisfies a predetermined standard, the control unit can determine that contact has been made and generate a predetermined vibration. Here, the predetermined reference can be set as appropriate according to the load characteristic when the push button switch is to be expressed.

  Furthermore, such a press detection part can be comprised according to the contact detection system in a touch panel. For example, in the case of the resistance film method, a strain gauge sensor, a piezoelectric element, or the like is used by associating the magnitude of the resistance according to the size of the contact area with the pressing load (force) on the operation area of the touch panel. It can be configured without. Alternatively, in the case of the capacitance method, the capacitance can be configured without using a strain gauge sensor, a piezoelectric element, or the like by associating the size of the capacitance with a pressing load (force) on the operation area of the touch panel. it can.

  Further, the vibration unit is configured by using an arbitrary number of piezoelectric vibrators, is configured by providing a transparent piezoelectric element on the entire surface of the touch panel, or configured to rotate the eccentric motor once in one cycle of the drive signal. You can also do it. Furthermore, when the pressure detection unit and the vibration unit are configured using a piezoelectric element, the pressure detection unit and the vibration unit may be configured by sharing the piezoelectric element. This is because the piezoelectric element generates a voltage when pressure is applied and deforms when the voltage is applied.

  Further, as described above, when the magnitude (voltage value (data)) of the voltage of the piezoelectric element that also serves as the pressure detection unit satisfies a predetermined standard, the vibration unit drives the piezoelectric element to generate vibration. It can also be generated. Here, when the voltage level (voltage value (data)) of the piezoelectric element satisfies a predetermined reference, the voltage value (data) may reach a predetermined reference value, It may be when the value (data) exceeds a predetermined reference value or when a voltage value (data) equal to the predetermined reference value is detected.

  In the above-described embodiment, the configuration in which the touch panel is arranged on the upper surface of the display unit has been described. The electronic device according to the present invention is not limited to such a configuration, and the touch panel and the display unit can be separated from each other. However, the configuration in which the touch panel is arranged so as to overlap the upper surface of the display unit allows the operator to easily recognize the correspondence between the displayed image, the region where the operation input is detected, and the generated vibration. Can do.

  In addition, the display unit and the touch panel in the description of the above-described embodiment may be configured by an integrated device, for example, by providing both functions of the display unit and the contact detection unit on a common substrate. As an example of the configuration of the device in which both functions of the display unit and the contact detection unit are integrated as described above, a plurality of photoelectric conversion elements such as photodiodes are regularly arranged in a matrix electrode array of pixel electrodes included in the liquid crystal panel. Can be mentioned. This device displays an image with a liquid crystal panel structure, while reflecting the light of a backlight for liquid crystal display at the tip of a pen that touches and inputs a desired position on the surface of the panel. The reflected light is reflected by peripheral photoelectric conversion elements. The touch position can be detected by receiving the light.

  The vibration unit may be configured to vibrate the touch panel indirectly by vibrating the electronic device based on a vibration motor (eccentric motor) or by arranging a piezoelectric element on the touch panel. The touch panel may be configured to vibrate directly.

  Moreover, in each embodiment mentioned above, the through-hole 30a which penetrates the back surface of the elastic member 30 as a hole of the elastic member 30 was demonstrated.
