  FIG. 3 is a plan view of the organic EL panel unit 20 as viewed from the Y2 direction. FIG. 4 is a view showing a cross section when the organic EL panel unit 20 of FIG. 3 is cut along the line AA. Note that a lead wire that is connected to the input terminal portion 26 and the input terminal portion 46 described later and supplies power to the transparent electrode layer 29 and the metal electrode layer 49 is not shown.

  As shown in FIG. 3, the organic EL panel unit 20 includes, for example, a transparent electrode layer 29 on a transparent glass substrate 21 having a substantially square shape with a length T13 in the Z direction and a length S13 in the X direction of 137.5 mm. The organic EL panel main body 22 is formed by laminating the (anode), the organic light emitting layer 39, and the metal electrode layer 49 (cathode) serving also as a reflective layer in this order. A layer composed of the transparent electrode layer 29, the organic light emitting layer 39, and the metal electrode layer 49 is referred to as a laminated portion 27. Furthermore, it has a hygroscopic sheet 23 and a sealing plate 24 disposed on the organic EL panel main body 22. Further, the space 25 between the glass substrate 21 and the sealing plate 24 is filled with nitrogen gas, and the acoustic characteristics are set differently from the case where air is sealed. By appropriately selecting a gas to be sealed in the space 25, acoustic characteristics corresponding to the type of gas can be obtained.

  As the glass substrate 21, for example, a glass plate having a Y-direction thickness D11 of 0.7 mm, a Z-direction length T11, and an X-direction length S11 of 300 mm can be used.

  The transparent electrode layer 29 is made of, for example, indium tin oxide or indium zinc oxide with a thickness of about 130 nm. In this embodiment, indium tin oxide is used. The organic light-emitting layer 39 is a low-molecular compound, specifically, bis [N- (1-naphthyl) -N-phenyl] benzidine having a thickness of about 60 nm as a hole transport layer from the transparent electrode layer 29 side of the anode and an electron transport layer / light emitting layer. It is formed of a film-forming layer in which a layer made of tris (quinolinolato) aluminum complex having a thickness of about 70 nm and a layer made of lithium fluoride having a thickness of about 1 nm are stacked as an electron injection layer. The metal electrode layer 49 is formed of aluminum with a thickness of about 120 nm. Each of these layers 29, 39, 49 is formed into a substantially square shape having a length T12 in the Z direction and a length S12 in the X direction of 122 mm each by a thin film forming method represented by a vacuum deposition method, for example. An input terminal portion 26 is formed on one side portion of the transparent electrode layer 29, and an input terminal portion 46 is formed on one side portion of the metal electrode layer 49, and the input terminal portion 26 and the input terminal portion 46 are formed on the laminated portion 27. It protrudes from the edge.

  The two hygroscopic sheets 23 have, for example, a Y-direction thickness of 0.3 mm, a Z-direction length of 40 mm, and an X-direction length of 30 mm. The two hygroscopic sheets 23 are accommodated side by side in a recess of a sealing plate 24 to be described later, with a space 25 therebetween. Further, one surface of the moisture absorbing sheet 23 has an adhesive layer in advance, and the moisture absorbing sheet 23 is accommodated in the recess with the surface on which the adhesive layer is provided facing the sealing plate 24 side. Therefore, the hygroscopic sheet 23 is disposed in contact with the metal electrode layer 49.

  The sealing plate 24 is made of, for example, a glass material. A large square recess (not shown) is formed on one surface, and two sheets of moisture absorbing sheets 23 are provided side by side with a space 25 in the recess. Is done. For example, the sealing plate 24 has a thickness of 1 mm in the Y direction and a length in the Z direction and a length in the X direction of 127.6 mm each. The recess is formed with a depth in the Y direction of 0.3 mm, a length in the Z direction, and a length in the X direction of 122.6 mm each. Therefore, a difference between the width of the sealing plate 24 in the X direction and the Z direction (127.6 mm) and the width of the recess in the X direction and the Z direction (122.6 mm) is formed as the peripheral portion 28 around the recess. . In the present embodiment, the peripheral edge 28 is formed with a width of 2.5 mm.

  The sealing plate 24 is disposed on the organic EL panel main body 22 so that the entire surface of the laminated portion 27 is located below the recess, and the peripheral portion 28 of the sealing plate 24 is in contact with the glass substrate 21. Become. Further, the contact portion between the peripheral edge 28 of the sealing plate 24 and the glass substrate 21 is fixed and sealed with an adhesive (not shown). Therefore, the laminated portion 27 and the hygroscopic sheet 23 are sealed between the glass substrate 21 and the sealing plate 24.

  In the organic EL panel unit 20 configured as described above, the light emitted from the organic light emitting layer 39 is emitted to the glass substrate 21 side through the transparent electrode layer 29 and reflected by the metal electrode layer 49, so that the glass substrate 21. Emits from the side. That is, the organic EL panel unit 20 is configured as a so-called bottom emission type organic EL panel.

  The cushioning material 11 disposed on both sides in the Y direction of the organic EL panel unit 20 is, for example, a thin sheet formed from an independently foamed urethane material, and the extension portion 15 is entirely inside the frame of the front frame 12. It is a rectangular frame of a size that can be placed over the circumference. The cushion material 11 is slightly smaller than the outer periphery of the extension portion 15 so as not to protrude from the extension portion 15 when the cushion material 11 is disposed on the extension portion 15, and the inner periphery of the extension portion 15. It is getting bigger.

  As shown in FIG. 2, the voice coil type vibration device 40 includes a magnetic circuit component 50 and a voice coil 60. The voice coil 60 has a cylindrical bobbin portion 61 and a flange portion 63 formed at one end of the bobbin portion 61, and a coil portion 62 is formed by winding a conducting wire around the bobbin portion 61. The coil part 62 is firmly wound around the bobbin part 61 so as not to move back and forth. Moreover, you may make it fix the coil part 62 with respect to the bobbin part 61 by adhering the bobbin part 61 and the coil part 62 with an adhesive agent as needed.

  FIG. 5 is a plan view when the organic EL panel speaker 1 is viewed from the Y2 side. FIG. 6 is an enlarged cross-sectional view illustrating a cross section taken along the line BB of FIG. FIG. 7 is an enlarged cross-sectional view showing a range C indicated by a dotted line in FIG. 6 in an enlarged manner.

  As shown in FIG. 7, the magnetic circuit configuration body 50 includes a plate 54, a magnet 55, and a yoke 56. The plate 54 has a disk shape and is made of an iron material that is a magnetic material. The magnet 55 has a ring shape and is made of an alloy containing neodymium. The yoke 56 has a disk portion 51 and a cylindrical portion 52, and has a shape called a so-called saddle yoke. The disk portion 51 has a larger diameter than the cylindrical portion 52, and a portion of the yoke 56 where the disk portion 51 protrudes from the outer periphery of the cylindrical portion 52 is formed as a flange portion 57.

  The diameter of the outer periphery of the magnet 55 is smaller than the inner periphery of the cylindrical portion 52 of the yoke 56. The magnet 55 is disposed between the outer peripheral surface of the magnet 55 and the inner peripheral surface of the cylindrical portion 52 of the yoke 56 so that a uniform gap 58 exists over the entire outer peripheral surface.

  The diameter of the outer periphery of the plate 54 is also smaller than the inner periphery of the cylindrical portion 52 of the yoke 56. The plate 54 is arranged between the inner peripheral surface of the cylindrical portion 52 of the yoke 56 and the outer peripheral surface of the plate 54 so that a uniform gap 59 exists as a magnetic gap over the entire outer periphery of the plate 54. The magnet 55 is fixed.

  The magnetic circuit component 50 and the voice coil 60 are configured such that the coil part 62 and the bobbin part 61 can be inserted into the gap 59 as a magnetic gap without contacting the plate 54 and the cylindrical part 52. For example, in the organic EL panel speaker 1 according to the present embodiment, the inner diameter L21 of the cylindrical portion 52 of the yoke 56 is 25.54 mm, and the diameter L26 of the plate 54 is 24.2 mm. The width is 0.67 mm. Further, the inner diameter L23 of the bobbin portion 61 of the voice coil 60 is 24.4 mm, and the outer diameter L24 including the coil portion 62 of the bobbin portion 61 is 25.34 mm.

  By doing so, the plate 54 can be inserted on the inner peripheral side of the bobbin portion 61 with an interval of 0.1 mm with respect to the inner peripheral surface of the bobbin portion 61, and the coil portion 62 and The bobbin portion 61 can be inserted with a space of 0.1 mm with respect to the inner peripheral surface of the cylindrical portion 52. The diameter L25 of the outer periphery of the cylindrical portion 52 of the yoke 56 is 29.98 mm, and the inner depth D22 from the opening end of the cylindrical portion 52 to the disk portion 51 is 5.5 mm. The magnet 55 has a thickness D23 of 3 mm, an outer diameter L26 of 23 mm, and an inner diameter L27 of 10 mm. The plate 54 has a thickness D24 of 2 mm. The winding width D25 of the coil portion 62 of the voice coil 60 is 3 mm, and the impedance is set to 4Ω.

  The rear frame 70 includes a rectangular outer frame portion and a cross-shaped inner frame portion 72 that is provided inside the outer frame portion and connects opposite side portions of the outer frame portion. Further, a rib portion 73 (see FIGS. 10 and 11) formed in a frame shape along the outer frame portion is formed on the front side of the outer frame portion. The length T24 in the Z direction and the length S24 in the X direction of the outer periphery of the outer frame portion are each 157.5 mm, for example. Further, the length T25 in the Z direction and the length S25 in the X direction of the outer periphery of the rib portion 73 are each 137.0 mm, for example. And the thickness D26 of the front-back direction of the inner peripheral side step part of the rib part 73 is 8 mm, for example. Both the outer frame portion and the inner frame portion 72 are formed on a wide surface, and as shown in FIG. 2, a circular portion 52 in which the cylindrical portion 52 of the yoke 56 of the magnetic circuit component 50 is inserted in the center of the inner frame portion 72. An opening 75 is formed. For example, the width W24 in the X direction of the inner frame portion 72 is, for example, 25 mm excluding the portion where the opening 75 is formed. The portion of the inner frame portion 72 where the opening 75 is formed is formed wide so that the diameter L28 of the opening 75 can be made large enough to allow the cylindrical portion 52 of the yoke 56 to be inserted. The diameter L28 of the opening 75 is, for example, 30 mm.

  Since the inner frame portion 72 has a cross shape, four rectangular openings 74 are formed between the inner side of the outer frame portion and the inner frame portion 72. The openings 74 are arranged in the four corner directions of the outer frame part, and are arranged at positions that are centrally symmetric with respect to the opening 75.

  The rear frame 70 having the above-described configuration is manufactured by, for example, hollowing out a rectangular plate from the portions corresponding to the opening 74 and the opening 75, and the outer frame and the inner frame 72. Are integrally formed. Since the inner frame portion 72 is formed with respect to the outer frame portion in this way, the rear frame 70 has increased rigidity against deformation.

  In the organic EL panel speaker 1 configured as described above, when an audio signal is input from a lead wire (not shown) connected to the coil unit 62, the voice coil type vibration device 40 is driven. That is, the voice coil 60 vibrates with respect to the magnetic circuit component 50. When the voice coil 60 vibrates, this vibration is transmitted to the sealing plate 24. As a result, the entire organic EL panel speaker 1 vibrates, and a sound is generated from the surface of the glass substrate 21 serving as a light emission surface.

  Thus, since the main-body part 10 is comprised by the display part and the audio | voice output part, people's attention can be called effectively. More specifically, there is no problem that the display and the sound are dissociated to cause confusion. For example, even when the field of view is poor due to smoke or the like, it is easy to find the emergency exit by proceeding in the direction of the voice. Moreover, since the main-body part 10 is comprised from the display part and the audio | voice output part, an installation space can be made small.

  In addition, since the organic EL panel unit 20 is used as a diaphragm for amplifying sound, it is not necessary to use a diaphragm separately, it is lightweight, and the place where it is attached is not easily limited.

  Further, in the organic EL panel speaker 1, since the heavy magnetic circuit component 50 of the voice coil type vibration device 40 is held by the rear frame 70, the sealing plate 24 can be thinned and the sound generation efficiency is improved. Can be high.

  Further, as described above, the periphery of the organic EL panel unit 20 of the organic EL panel speaker 1 is held in the outer frame portions of the front frame 12 and the rear frame 70. The organic EL panel unit 20 is easily deformed around. For this reason, the deformation | transformation of the organic electroluminescent panel part 20 can be effectively suppressed by hold | maintaining from the front and back by the outer frame part of the front frame 12 and the rear frame 70. FIG. Moreover, since the rigidity of the rear frame 70 is enhanced by providing the cross-shaped inner frame portion 72, the deformation of the organic EL panel portion 20 can be further suppressed.

  Further, the organic EL panel portion 20 of the organic EL panel speaker 1 described above is held between the front frame 12 and the rear frame 70 via the cushion material 11. Therefore, when the front frame 12 and the rear frame 70 are fixed to each other by the screws 81, the pressing force of the organic EL panel unit 20 acting between the front frame 12 and the rear frame 70 is reduced by the cushion material 11. And deformation of the organic EL panel unit 20 can be prevented. In addition, by providing the cushion material 11, the reproduction frequency in the low frequency range can be made suitable for hearing.

  Next, a method for manufacturing the above-described organic EL panel speaker 1 will be described. 8 to 11 are explanatory diagrams for explaining each manufacturing process of the organic EL panel speaker 1.

  First, the organic EL panel part 20 is produced. The organic EL panel part 20 forms the laminated part 27 on the glass substrate 21 in four places by sputtering or the like. For example, as shown in FIG. 8, a laminated portion 27 having a length T12 and a width S12 of 122 mm is formed on a glass substrate 21 having a thickness D11 of 0.7 mm and a length T11 and a width S11 of 300 mm each. An input terminal portion 26 is formed on one side portion of the transparent electrode layer 29, and an input terminal portion 46 is formed on one side portion of the metal electrode layer 49. The input terminal portion 26 and the input terminal portion 46 are laminated portions. Each layer 29, 39, 49 is formed so as to protrude from the edge of 27.

  After forming the laminated portion 27 on the glass substrate 21, as shown in FIG. 9, the glass substrate 21 is divided for each laminated portion 27, and a square organic EL panel main body 22 having a vertical length T13 and a horizontal length S13 of 137.5 mm each. Cut out.

  Next, as shown in FIG. 10, the surface of the moisture absorbing sheet 23 on which the adhesive sheet is mounted is accommodated in the recess with the surface facing the sealing plate 24. That is, the moisture absorbing sheet 23 is fixed in the recess of the sealing plate 24.

  Next, as illustrated in FIG. 11, the sealing plate 24 in which the hygroscopic sheet 23 is accommodated is placed so that the hygroscopic sheet 23 side faces the metal electrode layer 49, and the entire surface of the laminated portion 27 is below the recess. It arrange | positions on the organic electroluminescent panel main body 22 so that it may be located in the side. When the sealing plate 24 is disposed on the organic EL panel main body 22 so that the entire surface of the laminated portion 27 is located below the concave portion, the moisture absorbing sheet 23 having some elasticity is deformed loosely and the peripheral portion is a glass substrate. 21 is brought into contact. Therefore, the laminating portion 27 is sealed between the glass substrate 21 and the sealing plate 24 by fixing and sealing the contact portion between the peripheral portion of the sealing plate 24 and the glass substrate 21 with an adhesive. Is done.

  Next, one cushion material 11 is placed on the extended portion 15 inside the front frame 12 so as to overlap. And the organic EL panel part 20 is arrange | positioned inside the front frame 12 in which the cushion material 11 is arrange | positioned. The organic EL panel unit 20 is disposed on the front frame 12 in a state where the periphery of the glass substrate 21 is supported by the extending portion 15 with the cushion material 11 interposed therebetween.

  Subsequently, the other cushion material 11 is disposed on the periphery of the organic EL panel unit 20 accommodated inside the front frame 12. Then, the voice coil 60 is disposed on the organic EL panel unit 20. Then, the rear frame 70 is placed on the front frame 12 such that the rib portion 73 is fitted inside the front frame 12.

  The voice coil 60 and the rear frame 70 are configured such that the voice coil 60 is placed on the organic EL panel unit 20 while the coil unit 62 is passed through the opening 75 from the front side of the rear frame 70. Then, the rear frame 70 is placed on the front frame 12. By fitting the rib portion 73 inside the front frame 12, the organic EL panel portion 20 is sandwiched between the extended portion 15 of the front frame 12 and the rib portion 73 via the cushion material 11. The organic EL panel unit 20 is held by the front frame 12 and the rear frame 70.

  Next, screws 81 are respectively passed through a plurality of through holes 82 formed in the outer frame portion of the rear frame 70, and the screws 81 are engaged with the screw holes 14 formed on the back surface of the front frame 12, thereby forming the rear frame. 70 is fixed to the front frame 12. After the rear frame 70 is fixed to the front frame 12, the gap between the peripheral side surface of the coil portion 62 and the inner side surface of the opening portion 75 is made uniform over the entire circumference of the coil portion 62 using a jig. Next, the voice coil 60 is positioned, and in this positioned state, the flange portion 63 of the voice coil 60 is bonded and fixed to the sealing plate 24 of the organic EL panel portion 20.

  Subsequently, the magnetic circuit component 50 is attached to the rear frame 70 so that the cylindrical portion 52 of the yoke 56 is inserted into the opening 75. The diameter L21 of the inner peripheral surface of the cylindrical portion 52, the diameter L26 of the plate 54, the diameter L23 of the inner periphery of the bobbin portion 61, and the diameter L24 of the portion including the coil portion 62 are configured as described above. When the cylindrical portion 52 is inserted into the opening 75, the bobbin portion 61 and the coil portion 62 are inserted into the gap 59 that is a magnetic gap between the cylindrical portion 52 and the plate 54. When the cylindrical portion 52 of the yoke 56 is inserted into the opening 75, the magnetic circuit component 50 is positioned in the front-rear direction by the flange portion 57 coming into contact with the rear frame 70. The magnetic circuit component 50 is fixed to the rear frame 70 by fixing the flange portion 57 to the rear frame 70 with an adhesive, and the organic EL panel speaker 1 shown in FIG. 1 is configured.

  In the organic EL panel speaker 1 configured as described above, when an audio signal is input from a lead wire (not shown) connected to the coil unit 62, the voice coil type vibration device 40 is driven. That is, the voice coil 60 vibrates with respect to the magnetic circuit component 50. When the voice coil 60 vibrates, this vibration is transmitted to the sealing plate 24. As a result, the entire organic EL panel speaker 1 vibrates, and a sound is generated from the surface of the glass substrate 21 serving as a light emission surface.

  Next, an organic EL panel speaker system 100 using the above-described organic EL panel speaker 1 will be described. FIG. 12 is a block diagram illustrating the configuration of the organic EL panel speaker system 100.

  The organic EL panel speaker system 100 is mainly composed of an organic EL panel speaker 1, a control unit 200, and a sensor unit 300.

  The control unit 200 controls the organic EL panel speaker system 100. The control unit 200 applies an audio signal to the voice coil 60 when performing control for generating sound from the organic EL panel speaker 1. Moreover, the organic EL panel speaker 1 can be illuminated by applying a voltage to the input terminal unit 26 and the input terminal unit 46 of the organic EL panel under the control of the control unit 200.

  Moreover, the control part 200 does not need to perform illumination, when the display of the organic EL panel speaker 1 is not required. It is also possible to control so that only illumination is normally performed, and for example, audio is output only in an emergency.

  The sensor unit 300 in the present embodiment detects at least one of light, gas, smoke, temperature change, vibration, or liquid. In the present embodiment, sensor unit 300 sends a signal to control unit 200 when smoke is detected.

  By using the organic EL panel speaker system 100 as described above, the organic EL panel speaker system 100 that operates to illuminate, display, or output sound only when attention to information to be notified is necessary. it can. Therefore, although the organic EL panel speaker 1 is not usually bothered, the organic EL panel speaker 1 is urged to draw attention only when the information is necessary in an emergency or the like.

  In addition, when the sensor unit 300 detects smoke or the like, it is possible to automatically start illumination, display, or audio output for alerting in the event of a fire or the like.

  Next, an operation example of the organic EL panel speaker system 100 according to the present invention will be described.

  When smoke is generated by a fire or the like and the smoke is detected by the sensor unit 300, the sensor unit 300 sends a signal to the control unit 200.

  The control unit 200 starts light emission and audio output from the organic EL panel speaker 1 according to the signal. As the voice output, for example, a voice such as “A fire has occurred. Please evacuate” is output. By performing an example of light emission and audio output simultaneously, people's attention can be further raised.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and combination are possible.

  For example, in the present embodiment, the control unit 200 and the sensor unit 300 are separately provided, but the present invention is not limited to such a form. One or both of the control unit 200 and the sensor unit 300 may be provided integrally with the organic EL panel speaker 1.

  Moreover, in this Embodiment, although the organic electroluminescent panel speaker system 100 shall provide the sensor part 300, the sensor part 300 is not essential. However, by providing the sensor unit 300, an emergency such as a fire and an earthquake can be detected and operated.

  Moreover, in this Embodiment, although the organic EL panel speaker 1 functions in order to guide and guide to an emergency exit at the time of emergency, you may use other than the inside of a building. For example, the moving means may be provided on a bus, car, airplane, ship or other vehicle. Furthermore, you may use for uses other than the emergency guidance. For example, it can be used for guidance in a bus car or the like. In that case, while the bus is running, the display is not lit. On the other hand, if the sensor detects that the bus has stopped, in addition to lighting the indication that it is an exit, the bus stop The organic EL panel speaker system 100 can output the name and the guidance to the exit as a voice. Furthermore, it is good also as what can carry without being restricted to what is fixed to a building or a vehicle.

  Moreover, in this Embodiment, the organic EL panel part shall be displayed by making it the organic EL panel part 20 to which the film of the shape of the guide mark 4 was affixed. However, it is not limited to such a form. For example, a predetermined shape may be formed using ink or the like, or a predetermined portion of the organic EL may be caused to emit light with a desired color and shape.

  Moreover, in this Embodiment, although the display of the organic electroluminescent panel part 20 shall be a still image, it is not restricted to such a thing. For example, a so-called passive type organic EL panel speaker or organic EL element in which a cathode and an anode are simply crossed, an organic EL element is disposed at the crossing portion, and an electric current is instantaneously supplied by an external driving IC to emit light. A thin film transistor may be provided for each one, and the TFT may be a so-called active type organic EL panel speaker 1 that emits light while controlling the amount of current flowing through the pixel. When a moving image is reproduced by the organic EL panel speaker 1, the instantaneous maximum luminance can be reduced, thereby extending the life of the element and facilitating power saving. Furthermore, by linking the moving image and the sound or the moving image and the illumination, it is possible to more effectively attract people's attention and display information.

  For example, when the organic EL panel unit 20 can change the display, the organic EL panel speaker 1 can function as white illumination in a non-emergency situation. On the other hand, in the event of an emergency such as an earthquake, a mark similar to the guidance mark 4 can be displayed, and a display that enables guidance by voice can be provided.

  In the present embodiment, the organic EL panel speaker 1 having the organic light emitting layer 39 is used. However, an inorganic EL panel speaker using an inorganic material as a material that causes electroluminescence may be used. In the case of an inorganic EL panel speaker, an inorganic light emitting layer is formed instead of the organic light emitting layer 39. As the inorganic light emitting layer, for example, an inorganic vapor deposition layer such as zinc sulfide can be employed. Since the organic EL panel panel speaker 1 can obtain high luminance with low power, it has a feature that power consumption can be reduced in addition to improving visibility.

  Moreover, in this Embodiment, although it is set as the organic EL panel speaker 1 which has the voice coil type vibration apparatus 40, it is also possible to set it as the organic EL panel speaker which has another vibration actuator. Moreover, in this Embodiment, although the bottom emission type organic electroluminescent panel part 20 was illustrated, it is not restricted to such a thing. For example, a top emission type organic EL panel 20 may be used. The dimensions and the like exemplified in each description can be appropriately set by those skilled in the art.
