Glass for Mounting Vibration Components and Glass Diaphragm Module
[0001] The present invention relates to glass for mounting vibration components and a glass diaphragm module.
[0002] Patent Document 1 discloses a structure in which a vibrator is attached to the rear glass of a vehicle.
[0003] International Publication No. 2024 / 070584
[0004] In the structure of Patent Document 1, the rear glass functions as a speaker by being vibrated by the vibrator. By the way, when vibration components such as a vibrator vibrate, the mounting state of the vibration components may change. Even when the mounting state of the vibration components deteriorates, a structure is required to suppress the vibration components from falling off the glass plate.
[0005] An object of the present invention is to obtain glass for mounting vibration components and a glass diaphragm module that can suppress the vibration components from falling off the glass plate.
[0006] The glass for mounting vibration components according to the present invention includes a glass plate constituting a window glass, a vibration component fixing portion provided on the main surface of the glass plate to which a vibration component for vibrating the glass plate is fixed, and a wiring connection portion provided on the main surface of the glass plate to which a first wiring extending from the vibration component and a second wiring extending from a power source outside the glass plate are connected. The wiring connection portion is adhered to the main surface of the glass plate via an adhesive layer.
[0007] In the glass for mounting vibration components and the glass diaphragm module according to the present invention, it is possible to suppress the vibration components from falling off the glass plate.

This is a cross-sectional view corresponding to Figure 2, showing a modified glass diaphragm module.
[0009] A preferred embodiment of the glass diaphragm module according to the first embodiment will be described below with reference to the drawings. While the following description will focus on the application of the glass diaphragm module to vehicle windows, the glass diaphragm module according to the present invention may be applied to other moving objects such as airplanes, helicopters, ships, and trains, not just vehicles. Furthermore, the glass diaphragm module according to the present invention may be applied to the windows of buildings and other structures.
[0010] <First Embodiment> The glass diaphragm module 10 according to the first embodiment will be described with reference to Figure 1.
[0011] Figure 1 is a schematic front view of the glass diaphragm module 10 as seen from the main surface side. As shown in Figure 1, in this embodiment, the glass diaphragm module 10 is applied to the rear window (back window) of a vehicle. The glass diaphragm module 10 comprises a glass 11 for mounting the vibrating component, which includes the rear window 12, and a vibrating component 16 attached to the rear window 12.
[0012] The rear window 12 constitutes the vehicle's window glass and is fixed to the vehicle body in a state where it cannot be raised or lowered. While the rear window 12 is often a single pane of glass, it may also be laminated glass, where two glass plates are bonded together with a resin intermediate layer. The rear window 12 is formed from transparent or translucent inorganic glass. Examples of inorganic glass that can be used include soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass.
[0013] If the rear glass 12 is inorganic glass and single-pane glass, it is preferable that the rear glass 12 is tempered glass. Tempered glass is glass on which a compressive stress layer has been formed, and may be either air-cooled tempered glass or chemically tempered glass. If the tempered glass is physically tempered glass (for example, air-cooled tempered glass), a compressive stress layer may be formed on the glass surface by an operation other than slow cooling, such as rapidly cooling a uniformly heated glass plate from a temperature near its softening point during bending, thereby generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the inside of the glass. If the tempered glass is chemically tempered glass, a compressive stress layer may be formed on the glass surface after bending by an ion exchange method or the like.
[0014] If the rear window 12 is laminated glass in which two glass plates are bonded together with a resin intermediate layer, both glass plates may be untempered glass, one may be tempered glass, or both may be tempered glass. If both are tempered glass, both may be air-cooled tempered glass, both may be chemically tempered glass, or one may be air-cooled tempered glass and the other may be chemically tempered glass.
[0015] The rear glass 12 may be formed from organic glass. Examples of organic glass that can be used include PMMA (polymethyl methacrylate) resin, PC (polycarbonate) resin, PS (polystyrene) resin, PET (polyethyleneterephthalate) resin, PVC (polyvinyl chloride) resin, and cellulose resin.
[0016] When the rear glass 12 is a single pane of glass, the thickness of the rear glass 12 is preferably 0.5 mm or more, more preferably 1.0 mm or more, and even more preferably 1.5 mm or more. This improves the rigidity and strength of the rear glass 12, making it easier for the piston to vibrate. Also, when the rear glass 12 is a single pane of glass, from the viewpoint of reducing the weight of the glass diaphragm module 10, the thickness of the rear glass 12 is preferably 10.0 mm or less, more preferably 7.0 mm or less, and even more preferably 5.0 mm or less.
[0017] When the rear glass 12 is made of laminated glass in which two glass plates are bonded together by a resin intermediate layer, the thickness of the pair of glass plates constituting the rear glass 12 is preferably 0.5 [mm] or more, more preferably 1.0 [mm] or more, and even more preferably 1.5 [mm] or more. The thickness of the pair of glass plates constituting the rear glass 12 may be the same or different, but it is preferable that they be the same thickness from the viewpoint of stabilizing sound pressure. Furthermore, the total thickness of the rear glass 12 is preferably 1.0 [mm] or more, more preferably 2.0 [mm] or more, and even more preferably 3.0 [mm] or more. Also, from the viewpoint of reducing the weight of the glass diaphragm module 10, it is preferably 10.0 [mm] or less, more preferably 8.0 [mm] or less, and even more preferably 6.0 [mm] or less.
[0018] When the rear glass 12 is made of laminated glass, the intermediate layer can be a resin film containing a thermosetting adhesive material such as a transparent polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) resin film, silicone (PDMS), polyurethane, fluorine, polyethylene terephthalate, or polycarbonate. The intermediate layer may also contain materials to enhance sound insulation, increase rigidity, and absorb ultraviolet and infrared rays. The intermediate layer may be liquid or gel-like. Examples of liquid intermediate layers include water, oil, organic solvents, liquid polymers, ionic liquids, and mixtures thereof. More specifically, examples include propylene glycol, dipropylene glycol, tripropylene glycol, straight silicone oil (dimethyl silicone oil, methylphenyl silicone oil, methyl hydrogen silicone oil), modified silicone oil, acrylic acid polymers, liquid polybutadiene, glycerin paste, fluorine-based solvents, fluorine-based resins, acetone, ethanol, xylene, toluene, mineral oil, and mixtures thereof. In particular, it is preferable to include at least one selected from the group consisting of propylene glycol, dimethyl silicone oil, methylphenyl silicone oil, methyl hydrogen silicone oil, and modified silicone oil, and it is more preferable to have propylene glycol or silicone oil as the main component. Specifically, examples of gel-like intermediate layers include carbon-based, fluorine-based, or silicone-based polymer materials. Specifically, examples include ABS, AES, AS, CA, CN, CPE, EEA, EVA, EVOH, IO, PMMA, PMP, PP, PS, PVC, RB, TPA, TPE, TPEE, TPF, TPO, TPS, TPU, TPVC, AAS, ACS, PET, PPE, PA6, PA66, PBN, PBT, PC, POM, PPO, ETFE, FEP, LCP, PEEK, PEI, PES, PFA, PPS, PSV, PTFE, PVDF, silicone, polyurethane, PI, PF, PVB, TAC, polyolefin, acrylic and its copolymer resins, etc. Alternatively, composite materials combining the above materials may be used. The above materials may be used individually or in combination of two or more types.Furthermore, tackifiers and plasticizers may be included to provide adhesion. The thickness of the intermediate layer may be, for example, 0.1 [μm] to 3.0 [mm], 1.0 [μm] to 2.8 [mm], or 3.0 [μm] to 2.6 [mm]. If the rear glass 12 is laminated glass, a dimmable film that electrically varies the visible light transmittance may be sandwiched between the two glass plates. Examples of dimmable films that can be used include TN (Twisted Nematic) type liquid crystal film, VA (Vertical Alignment) type liquid crystal film, polymer dispersed liquid crystal (PDLC) film, suspended particle device (SPD) film, polymer network liquid crystal (PNLC) film, guest host liquid crystal film, electrochromic material, and photochromic material. Glass on which an image is displayed on part or all of the glass is also conceivable. A liquid crystal film may be sandwiched as a method for displaying the image. Alternatively, a projection screen film may be sandwiched between the glass plates. Furthermore, some or all of the glass may be equipped with film-like solar cell elements for generating electricity from sunlight. To ensure visibility as a vehicle window, it is generally preferable to use transparent films with excellent transparency. These functions can be imparted not only by sandwiching the film between the glass plates, but also by directly microfabrication, printing, transfer, or application of the film to the glass surface, as long as the glass speaker's function is not compromised.
[0019] In this embodiment, the rear glass 12 is formed in a substantially trapezoidal shape with the vehicle's width direction as the longitudinal direction, and the lower edge is longer than the upper edge. Furthermore, a light-shielding layer 13 of a predetermined width is provided on the outer periphery of the rear glass 12, which is formed of a color ceramic layer such as black, dark color, or white, or a color ink layer printed with organic or inorganic ink. Note that the present invention may also be applied to a structure without the light-shielding layer 13.
[0020] The rear glass 12 is constructed such that adhesives and other materials cannot be seen from outside the vehicle by the light-shielding layer 13. The light-shielding layer 13 is provided continuously around the outer edge of the rear glass 12, but it may have at least a portion of the area where the light-shielding layer is not provided.
[0021] Furthermore, a defogger (not shown) may be formed on the interior surface of the rear window 12 to clear fog (for anti-fogging). The defogger has a plurality of heater wires extending in the width direction of the rear window 12 and a pair of busbars extending vertically near both sides of the rear window 12, with a plurality of heater wires formed between the pair of busbars. The defogger is formed by printing and firing a silver paste containing silver powder and glass frit onto the surface of the rear window 12.
[0022] Furthermore, if the rear glass 12 is equipped with conductive wires (for example, defoggers and antennas) formed by printing and baking a paste containing a conductive material (for example, silver paste) onto the main surface on the interior side of the vehicle, it is preferable that the vibration component 16 be mounted so as not to overlap with the conductive wires.
[0023] Furthermore, a coating film may be formed on the rear glass 12. As the coating film, a Low-E (Low Emissivity) film, an AG (Anti-Glare) film, an AR (Anti-Reflection) film, an AF (Anti-Fingerprint) film, a UV (ultraviolet) cut film, an anti-fogging film, an anti-mold film, and a water-repellent film may be used.
[0024] Furthermore, the rear glass 12 may be colored glass baked with blue, red, green, gray, etc., or it may be privacy glass. Privacy glass is glass with lower transparency than green glass and clear glass, and is also called dark gray glass. In the rear glass 12, the privacy glass is Fe 2 O 3 This can be achieved by adjusting the total iron content converted to iron. The visible light transmittance of privacy glass can be adjusted to approximately 40-50% when the plate thickness is 1.8 mm, and approximately 30-45% when the plate thickness is 2.0 mm.
[0025] Figure 2 is an enlarged cross-sectional view showing the state when cut along the line 2-2 in Figure 1. As shown in Figures 2 and 1, the main surface of the rear glass 12 is provided with a vibration component fixing portion 14 to which a vibration component 16 that excites the rear glass 12 is fixed.
[0026] In this embodiment, the vibration component fixing portion 14 is set in the area of the light-shielding layer 13 and is provided with an adhesive layer 15. The adhesive layer 15 is circular in shape when viewed from the front, corresponding to the shape of the vibration component 16. For example, an adhesive such as adhesive tape formed in sheet form can be used as the adhesive layer 15. In addition, for example, adhesives such as acrylic, silicone, urethane, epoxy, phenol, and epoxy silicone adhesives, or adhesives having properties such as thermosetting, moisture curing, two-component mixing curing, ultraviolet curing, visible light curing, and anaerobic curing can be used as the adhesive layer 15.
[0027] The thickness of the adhesive layer 15 should be 3.0 mm or less, preferably 1.0 mm or less, more preferably 0.5 mm or less, and especially preferably 0.2 mm or less, as a thinner layer allows vibrations from the vibrating component 16 to be transmitted more effectively to the rear glass 12.
[0028] A wiring connection section 27 is provided on the main surface of the rear glass 12. The wiring connection section 27 is configured to connect a first wiring 18 extending from the vibration component 16 and a second wiring 22 extending from a power source outside the rear glass 12. A detailed explanation follows below.
[0029] The first wiring 18 extends from the vibrating component 16, and electricity can be supplied to the vibrating component 16 via the first wiring 18. The vibrating component 16 is an actuator that vibrates the rear glass 12 in response to an electrical signal input from the first wiring 18. In this embodiment, the vibrating component 16 is, as an example, a voice coil motor including a coil and a magnetic circuit. When current flows through the coil, vibration is generated by the interaction between the coil and the magnetic circuit, causing the rear glass 12 to vibrate (excite). The direction of vibration is in the thickness direction of the rear glass 12 (vibrating component 16). Note that the vibrating component 16 is not limited to a voice coil motor; any actuator capable of transmitting the desired vibration to the rear glass 12 can be used, such as a piezo actuator or other actuators besides a voice coil motor.
[0030] A first connector 20, which constitutes a wiring connection section 27, is provided at the tip of the first wiring 18. A second connector 24, which connects to the first connector 20, is provided at the tip of the second wiring 22 extending from the power supply. In other words, the first connector 20 is configured to be connectable to the second connector 24 at the tip of the second wiring 22. In this embodiment, as an example, a vibration component 16 is provided at the bottom of the rear glass 12, and the first wiring 18 extends upward from the vibration component 16. The second wiring 22 extends downward from the top, and the first connector 20 and the second connector 24 are connected in the vertical direction.
[0031] In the wiring connection section 27, the second connector 24 is bonded to the rear glass 12 via an adhesive layer 26. In this embodiment, as an example, the first connector 20 is not bonded to the rear glass 12. Therefore, the structure allows the first connector 20 to be removed simply by unplugging it from the second connector 24. However, the structure is not limited to this, and a structure in which the first connector 20 is bonded to the rear glass 12 via an adhesive layer 26 may be adopted, as shown in the modified example in Figure 9.
[0032] A first clip 30 for holding the first wiring 18 is provided between the vibration component fixing part 14 and the wiring connection part 27. The first clip 30 is provided between the vibration component 16 and the first connector 20 and is bonded to the rear glass 12 via an adhesive layer 28.
[0033] The first clip 30 is made of, for example, resin, and comprises a base portion 30A and a holding arm portion 30B. The base portion 30A is formed in a substantially rectangular shape when viewed from the front, but is not limited to this and may have other shapes.
[0034] The retaining arm portion 30B is provided on the upper surface of the base portion 30A and is formed in a substantially arch shape with a space through which the first wiring 18 is inserted. An opening 30C is also formed in the retaining arm portion 30B. The opening 30C is positioned in a direction different from the vibration direction of the vibrating component 16, and in this embodiment, as an example, it is positioned perpendicular to the vertical direction, which is the extending direction of the first wiring 18.
[0035] Here, as shown in Figure 1, the distance L1 between the vibrating component 16 and the holding arm portion 30B of the first clip 30 is preferably shorter than twice the diameter of the vibrating component 16, from the viewpoint of suppressing the flapping of the first wiring 18. Furthermore, the distance L1 is more preferably shorter than 1.5 times the diameter of the vibrating component 16, and even more preferably shorter than the diameter of the vibrating component 16.
[0036] On the other hand, the distance L2 from the first connector 20 to the holding arm portion 30B of the first clip 30 is preferably shorter than twice the diameter of the vibrating component 16, from the viewpoint of suppressing the flapping of the first wiring 18. Furthermore, the distance L2 is more preferably shorter than 1.5 times the diameter of the vibrating component 16, and even more preferably shorter than the diameter of the vibrating component 16.
[0037] A second clip 34 is provided above the second connector 24 to hold the second wiring 22. The second clip 34 is located between the power supply and the second connector 24 and is bonded to the rear glass 12 via an adhesive layer 32.
[0038] The second clip 34 is made of, for example, resin, and consists of a base portion 34A and a holding arm portion 34B. The base portion 34A is formed in a substantially rectangular shape when viewed from the front, but is not limited to this and may have other shapes.
[0039] The retaining arm portion 34B is provided on the upper surface of the base portion 34A and is formed in a substantially arch shape with a space through which the second wiring 22 is inserted. An opening 34C is also formed in the retaining arm portion 34B. The opening 34C is positioned in a direction different from the vibration direction of the vibrating component 16, and in this embodiment, as an example, it is positioned perpendicular to the vertical direction, which is the extending direction of the second wiring 22.
[0040] At least one of the first wiring 18 and the second wiring 22 may be provided with a reinforcing member. The reinforcing member is preferably made of a material with higher hardness than the first wiring 18 or the second wiring 22. The reinforcing member may be attached to at least one of the following locations: between the vibrating component 16 of the first wiring 18 and the first clip 30, and between the first clip 30 of the first wiring 18 and the wiring connection portion 27. The reinforcing member may also be attached to at least one of the following locations: between the power supply of the second wiring 22 and the second clip 34, and between the second clip 34 of the second wiring 22 and the wiring connection portion 27. Furthermore, the space between the vibrating component 16 of the first wiring 18 and the wiring connection portion 27 may be reinforced with a reinforcing member. In addition, the space between the power supply of the second wiring 22 and the wiring connection portion 27 may be reinforced with a reinforcing member. Reinforcement sleeves, wires, etc., can be used as reinforcing members.
[0041] Also, at least one of the first wiring 18 and the second wiring 22 may include a heat insulating member. The heat insulating member may be attached to at least one of between the vibrating component 16 of the first wiring 18 and the first clip 30 and between the first clip 30 of the first wiring 18 and the wiring connection part 27. Further, the heat insulating member may be attached to at least one of between the power source of the second wiring 22 and the second clip 34 and between the second clip 34 of the second wiring 22 and the wiring connection part 27. Moreover, the part between the vibrating component 16 of the first wiring 18 and the wiring connection part 27 may be constituted by a heat insulating member. Furthermore, the part between the power source of the second wiring 22 and the wiring connection part 27 may be constituted by a heat insulating member. As the heat insulating member, an insulating member is preferable. For example, foam materials such as foamed polyurethane, gel materials, silicone resins, porous materials, glass wool with heat-resistant and moisture-proof paper, polystyrene foam, glass wool, rock wool, aluminum foil, etc. can be used. Note that a reinforcing member and a heat insulating member may be used in combination.
[0042] Furthermore, at least one of the first wiring 18 and the second wiring
[0042] 22 may be directly adhered to the rear glass 12 through an adhesive layer. For example, in FIG.
[0043] 2, the second wiring
[0042] 22 may be adhered to the rear glass 12 by an adhesive layer above the second clip 34.
[0043] Note that, as a connection method between the first connector 20 and the second connector
[0044] 24, known connection methods such as mechanical fastening by insertion, fitting, crimping, screws, etc. can be used. As connection methods other than connection by mechanical fastening, the first connector 20 and the second connector
[0044] 24 may be connected by pressure welding, may be connected with a conductive adhesive, or may be connected by soldering. The first connector 20 and the second connector
[0044] 可以使用公知のコネクタ及び公知の端子である嵌合式コネクタ、ギボシ端子、差込端子、ワンタッチコネクタ、ハウジングコネクタ、バナナプラグ、Y字プラグなどを使用することができる。
[0044] In addition, at least one of the first connector 20 and the second connector 24 may have functions such as an amplifier function, a digital signal processing function, a filter function such as a low-pass filter, a high-pass filter, and a band-pass filter, a resistor for protecting an actuator or an electronic device, a microphone, and a vibration information collection function such as an acceleration sensor.
[0045] The second connector 24 is connected to the first connector 20 and to a connector different from the first connector 20, and may also be connected to a vibration component different from the vibration component 16 connected to the first connector 20 and the first wiring 18. That is, a plurality of connectors may be connected to the second connector 24, and the second connector 24 may be configured to be connected to a plurality of vibration components via a plurality of wirings. In that case, the wiring connection portion 27 may have an electrical signal branching function. The electrical signal branching function may include a distribution function for branching the same electrical signal and an LR branching function for separating electrical signals such as stereo audio into left and right. Further, three or more connectors may be connected to the second connector 24.
[0046] In the present embodiment, the vibration component 16 is directly adhered to the vibration component fixing portion 14 via the adhesive layer 15, but the present invention is not limited to this, and the vibration component 16 may be attached via a mounting member. The mounting member may be formed of a metal including stainless steel, aluminum, titanium, etc., and at least a part or all of the mounting member may be formed of a resin such as plastic. As the plastic, general engineering plastics such as ABS-based, PVC-based, PC-based, PP-based, PBT-based, PA66-based, and PPS-based may be used, or fiber reinforced plastics including glass fiber and carbon fiber may be used.
[0047] The mounting member may be formed to have a smaller diameter than the vibration component 16 or may be formed to have a larger diameter than the vibration component 16. Further, the fixing method of the mounting member and the vibration component 16 is not particularly limited, and the mounting member and the vibration component 16 may be configured to be mechanically attached by bolts, rivets, claws, etc., or may be attached by an adhesive material or the like.
[0048] (Operation) Next, the operation of the present embodiment will be described.
[0049] According to the glass 11 for mounting the vibrating component and the glass diaphragm module 10 of this embodiment, the wiring connection portion 27 is bonded to the main surface of the rear glass 12 via the adhesive layer 26. Therefore, even if the adhesive state of the adhesive layer 15 changes due to the continuous vibration of the vibrating component 16 and the vibrating component 16 detaches from the rear glass 12, the first connector 20 and the second connector 24 at the wiring connection portion 27 are bonded to the rear glass 12, which prevents the vibrating component 16 from falling off.
[0050] Furthermore, since the first connector 20 provided at the end of the first wiring 18 and the second connector 24 provided at the end of the second wiring 22 are connected, if tension is applied to the first wiring 18 due to the weight of the vibrating component 16, the second wiring 22 can bear the tension via the second connector 24.
[0051] Furthermore, since the first clip 30 is adhered to the main surface of the rear glass 12, when the vibrating component 16 comes off, the first wiring 18 can catch on the first clip 30, more reliably preventing the vibrating component 16 from falling off. In particular, since the opening 30C of the first clip 30 in this embodiment opens in a direction different from the vibration direction of the vibrating component 16, even if the first wiring 18 moves in a wave-like manner due to the vibration of the vibrating component 16, it is possible to prevent the first wiring 18 from coming off the first clip 30.
[0052] Furthermore, if the first wiring 18 or the second wiring 22 has a reinforcing member attached to at least a portion of it, the flapping of the first wiring 18 or the second wiring 22 can be suppressed. In addition, even if the adhesive layer 15, adhesive layer 28 or adhesive layer 32 peels off, the vibration component 16, the first clip 30 or the second clip 34 can be prevented from falling off and hitting the occupants of the vehicle.
[0053] Furthermore, if the first wiring 18 or the second wiring 22 has an insulating material attached to at least a portion of it, it is possible to suppress the propagation of heat generated by the first wiring 18 or the second wiring 22 to the rear glass 12, and at the same time suppress the propagation of heat from the rear glass 12 to the first wiring 18 or the second wiring 22.
[0054] <Second Embodiment> The glass diaphragm module 40 according to the second embodiment will be described with reference to Figure 3. Components similar to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted as appropriate.

The glass diaphragm module 40 comprises a glass 41 for mounting a vibrating component, which includes the roof glass 42, and a vibrating component 16 attached to the roof glass 42.
[0056] The roof glass 42 constitutes the vehicle's window glass and is fixed to the vehicle body in a non-movable position, but it may be slidable in the front-to-back or left-to-right direction. While the roof glass 42 is often single-pane glass, it may also be laminated glass, where two glass plates are bonded together with a resin intermediate layer. The roof glass 42 is formed from transparent or translucent inorganic glass. Examples of inorganic glass that can be used include soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass.
[0057] The roof glass 42 is provided with a light-shielding layer 43 similar to the light-shielding layer 13, and a vibration component fixing part 14 is provided on the light-shielding layer 43. A vibration component 16 is attached to the vibration component fixing part 14 via an adhesive layer 15.
[0058] A wiring connection section 46 is provided either in front of or behind the vibration component fixing section 14. A second connector 24 is bonded to the wiring connection section 46 via an adhesive layer 44. The first connector 20 is connected to the second connector 24. In this embodiment, the second connector 24 and the first connector 20 are connected vertically.
[0059] A first clip 30 is provided between the vibrating component 16 and the first connector 20, and a second clip 34 is provided between the second connector 24 and the power supply.
[0060] In this embodiment, the first connector 20 and the second connector 24 are connected vertically, making connection easier than in the first embodiment.
[0061] <Third Embodiment> The glass diaphragm module 50 according to the third embodiment will be described with reference to Figures 4 and 5. Components similar to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted as appropriate.
[0062] Figure 4 is a front view showing the glass diaphragm module 50 according to the third embodiment, and Figure 5 is an enlarged cross-sectional view showing the state cut along line 5-5 in Figure 4. As shown in Figures 4 and 5, the glass diaphragm module 50 of this embodiment is applied to the roof glass 42 of a vehicle. The glass diaphragm module 50 comprises a glass 41 for mounting vibrating components, including the roof glass 42, and a vibrating component 16 attached to the roof glass 42.
[0063] In this embodiment, similar to the second embodiment, a vibration component fixing portion 14 is provided on the light-shielding layer 43, and a vibration component 16 is attached to the vibration component fixing portion 14 via an adhesive layer 15.
[0064] On the other hand, a wiring connection section 54 is provided either in front of or behind the vibration component fixing section 14. At the wiring connection section 54, a support section 52 is provided on the main surface of the roof glass 42 via an adhesive layer 56.
[0065] The support portion 52 is formed in a roughly rectangular shape when viewed from the front, and is larger than the first connector 20 and the second connector 24. The first connector 20 and the second connector 24 are attached to the support portion 52 while connected.
[0066] The support portion 52 has a recess 52A through which the first wiring 18 and the second wiring 22 are inserted. The method of attaching the first connector 20 and the second connector 24 to the support portion 52 is not particularly limited. For example, the support portion 52 may be provided with a claw portion (not shown), and the first connector 20 and the second connector 24 may be locked with the claw portion. Alternatively, the first connector 20 and the second connector 24 may be attached to the support portion 52 by fitting them together. Furthermore, the first connector 20 and the second connector 24 may be attached to the support portion 52 with adhesive or a bonding agent.
[0067] A first clip 30 is provided between the vibrating component 16 and the support portion 52, and a second clip 34 is provided between the support portion 52 and the power supply.
[0068] In this embodiment, the first connector 20 and the second connector 24 are fixed to the roof glass 42 via the support portion 52, so that the first connector 20 and the second connector 24 can be easily removed from the roof glass 42. In addition, since a large adhesive area can be secured between the support portion 52 and the roof glass 42, the support portion 52 is less likely to fall off the roof glass 42.
[0069] <Fourth Embodiment> The glass diaphragm module 60 according to the fourth embodiment will be described with reference to Figure 6. Components similar to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted as appropriate.
[0070] Figure 6 is a cross-sectional view showing a glass diaphragm module 60 according to the fourth embodiment. As shown in Figure 6, the glass diaphragm module 60 of this embodiment is applied to the rear window 12 of a vehicle. The glass diaphragm module 60 comprises a glass 11 for mounting a vibrating component, including the rear window 12, and a vibrating component 16 attached to the rear window 12.
[0071] The rear window 12 is provided with a light-shielding layer 13, and a vibration component fixing part 14 is provided on the light-shielding layer 13. A vibration component 16 is attached to the vibration component fixing part 14 via an adhesive layer 15.
[0072] A wiring connection section 64 is provided above the vibration component fixing section 14. At the wiring connection section 64, a connection base section 62 is provided on the main surface of the rear glass 12 via an adhesive layer 66.
[0073] The connection base portion 62 is formed in a substantially rectangular shape when viewed from the front. The lower end of the connection base portion 62 is provided with a connection portion to which the first connector 20 is connected, and the first connector 20 is connected to this connection portion. The upper end of the connection base portion 62 is provided with a connection portion to which the second connector 24 is connected, and the second connector 24 is connected to this connection portion. In other words, the first connector 20 and the second connector 24 are each connected separately to the connection base portion 62.
[0074] An electrical path is formed inside the connection base portion 62, and the first connector 20 and the second connector 24 are configured to be electrically connected through this electrical path.
[0075] In this embodiment, since the first connector 20 and the second connector 24 are indirectly connected, even if the vibrating component 16 detaches from the rear glass 12, tension does not act on the second wiring 22, thus preventing the second wiring 22 from breaking. Furthermore, since the tension acting on the first wiring 18 is input to the connection base 62 via the first connector 20, firmly fixing the connection base 62 to the rear glass 12 prevents the vibrating component 16 from falling off.
[0076] <Fifth Embodiment> The glass diaphragm module 70 according to the fifth embodiment will be described with reference to Figures 7 and 8. Components similar to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted as appropriate.
[0077] Figure 7 is a front view showing a glass diaphragm module according to the fifth embodiment, showing the state before the first connector 20 and the second connector 24 are connected. Figure 8 is an enlarged cross-sectional view showing the state cut along line 8-8 in Figure 7. As shown in Figures 7 and 8, the glass diaphragm module 70 of this embodiment is applied to the rear window 12 of a vehicle. The glass diaphragm module 70 comprises a glass 11 for mounting the vibrating component, including the rear window 12, and a vibrating component 16 attached to the rear window 12.
[0078] The rear window 12 is provided with a light-shielding layer 13, and a vibration component fixing part 14 is provided on the light-shielding layer 13. A vibration component 16 is attached to the vibration component fixing part 14 via an adhesive layer 15.
[0079] Below the vibration component fixing section 14, a wiring connection section 73 is provided. At the wiring connection section 73, the flexible substrate 72 is bonded to the main surface of the rear glass 12 via adhesive layers 74 and 78.
[0080] The flexible substrate 72 is composed of a substantially strip-shaped and flexible wiring portion 72A, a first connection portion 72B provided at one end of the wiring portion 72A, and a second connection portion 72C provided at the other end of the wiring portion 72A.
[0081] The first connection portion 72B has adhesive layers 74 on both the left and right sides, and is bonded to the rear glass 12 by these adhesive layers 74. Electrodes 76 are also provided between the adhesive layers 74, and when the first connector 20 is connected to the first connection portion 72B, the first connector 20 and the electrodes 76 become electrically connected.
[0082] The second connection portion 72C has adhesive layers 78 on both the left and right sides, and is bonded to the rear glass 12 by these adhesive layers 78. Electrodes 80 are also provided between the adhesive layers 78, and when the second connector 24 is connected to the second connection portion 72C, the second connector 24 and the electrodes 80 become electrically connected.
[0083] In this manner, one end and the other end of the flexible substrate 72 are bonded to the main surface of the rear glass 12, the first connector 20 is connected to one end of the flexible substrate 72, and the second connector 24 is connected to the other end of the flexible substrate 72. This allows power to be supplied from the power source to the vibration component 16 via the flexible substrate 72, even if the first connector 20 and the second connector 24 cannot be directly connected.
[0084] Furthermore, even in structures where the distance between the first connector 20 and the second connector 24 is variable, such as with movable roof glass or side windows, the flexible circuit board 72 can maintain good conductivity.
[0085] Although the glass diaphragm module according to the embodiment has been described above, it goes without saying that it can be implemented in various forms without departing from the spirit of the present invention. In the above embodiment, a structure applied to the rear glass 12 and roof glass 42 as window glass has been described, but it is not limited to this. For example, it may be applied to the side door glass, rear quarter glass, and windshield of a vehicle.
[0086] Furthermore, the glass diaphragm module is not limited to vehicles; it can also be applied to building windows, and to other moving objects besides vehicles. For example, the glass plate module may be applied to trains, airplanes, helicopters, and drones.
[0087] Furthermore, in the above embodiment, a structure may be adopted to cut off the power supply to the vibrating component 16 when the vibrating component 16 detaches from the rear glass 12 or roof glass 42. For example, in the first embodiment, the first connector 20 may be structured to easily detach from the second connector 24 when it is pulled downwards. Alternatively, a sensor that detects vibrations of the rear glass 12 may be used to detect when the vibrating component 16 has detached from the rear glass 12, and a mechanism may be provided to stop the power supply from the power source to the vibrating component 16.
