Best Mode for Carrying Out the Invention

[0009] Hereinafter, a preferred embodiment of a glass diaphragm module according to the first embodiment will be described with reference to the drawings. In addition, although the case where the glass diaphragm module is applied to a vehicle window glass will be described below, the glass diaphragm module according to the present invention may be applied to moving bodies such as airplanes, helicopters, ships, and trains regardless of the vehicle. Further, the glass diaphragm module according to the present invention may be applied to window glass of buildings such as buildings. In addition, an arrow FR appropriately shown in each figure indicates the front of the vehicle, which is the front side in the vehicle longitudinal direction, an arrow LH indicates the left side in the vehicle width direction, and an arrow UP indicates the upper side of the vehicle, which is the upper side in the vehicle vertical direction. In the following description, when simply referring to the "front-rear direction", "width direction", and "vertical direction", they respectively represent the vehicle front-rear direction, the vehicle width direction, and the vehicle vertical direction. In addition, when referring to the left-right direction, it means the left-right direction in a state facing the front of the vehicle.

[0010] The glass diaphragm module 10 according to the embodiment will be described with reference to FIGS. 1 and 2.

[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 rear window 12 and a vibrating part 14 that vibrates the rear window to function as a speaker.

[0012] (Rear window) The rear window 12 constitutes the vehicle's window glass. The rear window 12 separates the interior of the vehicle from the exterior. The rear window 12 is fixed to the vehicle body in a state where it cannot be raised or lowered. The rear window 12 is often a single pane of glass, but it may also be laminated glass in which two glass plates are bonded together with a resin intermediate layer. The rear window 12 is made of 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] If 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, if 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, water, 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, polyolefins, acrylics and their copolymer resins, etc. Alternatively, composite materials combining the above materials are also possible. The above materials may be used individually or in combination of two or more.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 rectangular shape with the vehicle's width direction as the longitudinal direction. Furthermore, a light-shielding layer (not shown) of a predetermined width is provided on the outer periphery of the rear glass 12, formed from a color ceramic layer such as black, dark, 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 has a structure that prevents adhesives and other materials from being visible from the outside of the vehicle due to a light-shielding layer (not shown). The light-shielding layer is provided continuously around the outer edge of the rear glass 12, but there may be areas where the light-shielding layer is not provided in at least a part of it.

[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 several 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 conductor (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. Privacy glass can be achieved in the rear glass 12 by adjusting the total iron content converted to Fe2O3. The visible light transmittance of privacy glass can be adjusted to, for example, about 40-50% when the plate thickness is 1.8 mm, and about 30-45% when the plate thickness is 2.0 mm.

[0025] Figure 2 is a cross-sectional view showing the state when cut along line AA in Figure 1. As shown in Figures 2 and 1, a vibrating part 14 for exciting the rear glass 12 is provided on the main surface of the rear glass 12. Specifically, the vibrating part 14 is bonded to the main surface of the rear glass 12 by an adhesive part 16. In this embodiment, the vibrating part 14 is set, for example, in the area of ​​the light-shielding layer.

[0026] (Vibrating part) As shown in Figures 1 and 2, the vibrating part 14 is bonded to the rear glass 12 by an adhesive part 16. In other words, an adhesive part 16 is provided between the rear glass 12 and the vibrating part 14. In addition to the adhesive part 16, a waterproof part 18 is also provided between the rear glass 12 and the vibrating part 14. The arrangement of the adhesive part 16 and the waterproof part 18 between the rear glass 12 and the vibrating part 14 will be described later.

[0027] The vibrating section 14 has a vibrator as a vibrating component that generates vibration. In this embodiment, the vibrator is bonded to the rear glass 12. The vibrator is connected to a power source via a cable (not shown) and is an actuator that excites the rear glass 12 in response to an input electrical signal. As an example, the vibrator in this embodiment is a voice coil motor including a coil section and a magnetic circuit, with one of the coil section and the magnetic circuit fixed to the rear glass 12 and the other positioned to be movable relative to the rear glass 12. When current flows through the coil section, vibration is generated by the interaction between the coil section and the magnetic circuit, causing the rear glass 12 to vibrate (excite). The direction of vibration is in the thickness direction of the vibrator. Note that the vibrator 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.

[0028] In the above description, an example was given in which the transducer is directly bonded to the rear glass 12, but the present invention is not limited to this. For example, the vibrating unit 14 may have a transducer and a mounting member (transmission unit) to which the transducer is attached, and the mounting member with the transducer attached may be bonded to the rear glass 12. In this case, since the mounting member is bonded to the rear glass 12 and the transducer and the rear glass 12 are not in direct contact, the vibrations generated by the transducer are input to the rear glass 12 via the mounting member. That is, the mounting member transmits the vibrations generated by the transducer to the rear glass 12.

[0029] The mounting member may be made of a metal including stainless steel, aluminum, or titanium, or at least part or all of the mounting member may be made of a resin such as plastic. As the plastic, general engineering plastics such as ABS, PVC, PC, PP, PBT, PA66, and PPS may be used, or fiber-reinforced plastics including glass fibers or carbon fibers may be used.

[0030] The mounting member may be formed to the same diameter as the transducer, to a smaller diameter than the transducer, or to a larger diameter than the transducer. Furthermore, there are no particular limitations on the method of fixing the mounting member to the transducer; it may be configured to be mechanically attached using bolts, rivets, claws, etc., or it may be attached using adhesive or the like.

[0031] Alternatively, instead of a mounting member, the transducer may be attached to a long rod. In this case, one end of the rod with the transducer attached is bonded to the rear glass 12.

[0032] (Adhesive parts and waterproof parts) Next, the adhesive portion 16 and the waterproof portion 18 will be described using Figures 1 and 2. As described above, an adhesive portion 16 is provided between the rear glass 12 and the vibrating portion 14 to bond the rear glass 12 and the vibrating portion 14. In this embodiment, not only the adhesive portion 16 but also a waterproof portion 18 is provided between the rear glass 12 and the vibrating portion 14 to block some of the water that flows along the rear glass 12 toward the adhesive portion 16. The water that flows along the rear glass 12 toward the adhesive portion 16 is, for example, water droplets that have condensed on the rear glass 12.

[0033] The adhesive portion 16 is located below the waterproof portion 18. The adhesive portion 16 is located closer to the center of the vibration portion 14 than the waterproof portion 18. Multiple adhesive portions 16 are provided. Each adhesive portion 16 extends in a substantially straight line along the width direction of the rear glass 12. The width direction of the rear glass 12 is the left-right direction in the plane of Figure 1. The three adhesive portions 16 are arranged in a line at predetermined intervals along the vertical direction. Of the three adhesive portions 16 arranged along the vertical direction, the lowest adhesive portion 16 is formed to have the longest width and is provided over substantially the entire width of the vibrating portion 14. Of the three adhesive portions 16, the width lengths of the other two adhesive portions 16 are substantially the same. Note that the number, shape, and arrangement of the adhesive portions 16 are not limited to the above description and may be set as appropriate depending on the required adhesive strength, etc.

[0034] The ends of the adhesive portion 16 in the width direction are curved such that the central part in the vertical direction is located further outward in the width direction than the ends. In other words, the ends of each adhesive portion 16 in the width direction are curved such that the central part in the vertical direction protrudes the most.

[0035] For the adhesive portion 16, for example, an adhesive such as adhesive tape formed in sheet form can be used. Alternatively, for the adhesive portion 16, adhesives such as acrylic, silicone, urethane, epoxy, phenol, and epoxy silicone adhesives, or adhesives having properties such as thermosetting, moisture curing, two-component curing, ultraviolet curing, visible light curing, or anaerobic curing can be used.

[0036] The thickness of the adhesive portion 16 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 adhesive portion 16 allows vibrations from the vibrating portion 14 to be transmitted more effectively to the rear glass 12.

[0037] The waterproof section 18 is provided at the upper end of the vibrating section 14. The waterproof section 18 is provided above all adhesive sections 16. The waterproof section 18 extends in a substantially straight line along the width direction of the rear glass 12 (left-right direction in Figure 1). The waterproof section 18 is provided substantially parallel to the adhesive sections 16. The waterproof section 18 extends substantially horizontally.

[0038] The waterproof section 18 is provided to cover the adhesive section 16 from above. The width of the waterproof section 18 is longer than the width of all the adhesive sections 16 combined. The waterproof section 18 is provided so as to overlap all of the adhesive sections 16 when viewed from a direction along the vertical direction. Alternatively, the waterproof section 18 may be provided so as to overlap only a portion of the adhesive sections 16 when viewed from a direction along the vertical direction.

[0039] The material of the waterproof part 18 is not particularly limited as long as it is a material that can block water. For example, the waterproof part 18 may be an adhesive such as adhesive tape formed in a sheet. In the case of an adhesive, the waterproof part 18 is adhered to at least one of the rear glass 12 and the vibrating part 14.

[0040] Furthermore, for example, the waterproof portion 18 may be made of the same adhesive as the adhesive portion 16. That is, the waterproof portion 18 can be made of adhesives such as acrylic, silicone, urethane, epoxy, phenol, epoxy silicone, or adhesives that are thermosetting, moisture-curing, two-component mixed curing, ultraviolet curing, visible light curing, or anaerobic curing. When the waterproof portion 18 is made of adhesive, the waterproof portion 18 is bonded to the rear glass 12 and the vibrating portion 14. Therefore, the waterproof portion 18 also bonds the rear glass 12 and the vibrating portion 14, but in the glass diaphragm module 10 according to this embodiment, the adhesive portion 16 is configured so that even if the adhesive effect of the waterproof portion 18 is lost, the rear glass 12 and the vibrating portion 14 can be sufficiently bonded.

[0041] (Effects / Actions) According to this embodiment, the following effects and advantages are achieved. In the glass diaphragm module 10 according to this embodiment, the waterproof portion 18 is provided above the adhesive portion 16. As a result, the waterproof portion 18 blocks water droplets that travel from above towards the adhesive portion 16 via the rear glass 12. Therefore, it is difficult for water to come into contact with the adhesive portion 16, and thus deterioration of the adhesive portion 16 can be suppressed. Thus, changes in acoustic performance and peeling of the adhesive portion 16 caused by deterioration of the adhesive portion 16 can be suppressed.

[0042] Furthermore, in the glass diaphragm module 10 according to this embodiment, the waterproof section 18 is provided between the rear glass 12 and the vibrating section 14. As a result, the waterproof section 18 is hidden by the vibrating section 14. Therefore, the waterproof section 18 is difficult to see, which improves the aesthetic design of the glass diaphragm module 10.

[0043] Furthermore, if the adhesive portion 16 and the waterproof portion 18 are formed from the same material, the adhesive portion 16 and the waterproof portion 18 can be provided simultaneously, thus simplifying the work of providing the adhesive portion 16 and the waterproof portion 18.

[0044] Furthermore, in the glass diaphragm module 10 according to this embodiment, the widthwise length of the waterproof portion 18 is longer than the widthwise length of the adhesive portion 16. This makes it easier for the waterproof portion 18 to block water that travels along the rear glass 12 from above towards the adhesive portion 16. Therefore, water is less likely to come into contact with the adhesive portion 16, thus further suppressing the deterioration of the adhesive portion 16.

[0045] <First variation> Referring to Figure 3, a glass diaphragm module 20 according to the first modified example of the above embodiment will be described. In this modified example, the arrangement of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those of the above embodiment, and their detailed descriptions will be omitted.

[0046] As shown in Figure 3, the waterproof portion 28 provided on the glass diaphragm module 20 according to this modified example is inclined such that one end in the width direction is located above the other end. The waterproof portion 28 is inclined with respect to the horizontal direction and the extension direction of the adhesive portion 16.

[0047] In this way, because the waterproof section 28 is sloped, water does not accumulate on the upper surface of the waterproof section 28, thus suppressing deterioration of the waterproof section 28 due to water.

[0048] <Second variation> Referring to Figure 4, a glass diaphragm module 30 according to a second modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those in the above embodiment, and their detailed descriptions will be omitted.

[0049] As shown in Figure 4, the waterproof section 38 provided in the glass diaphragm module 30 according to this modified example has an upper waterproof section 38A and a lower waterproof section 38B provided below the upper waterproof section 38A. The upper waterproof section 38A and the lower waterproof section 38B are arranged side by side in the vertical direction. The upper waterproof section 38A and the lower waterproof section 38B are provided substantially parallel to each other. The widthwise length of the upper waterproof section 38A is shorter than the widthwise length of the lower waterproof section 38B.

[0050] By providing multiple waterproof sections in this way, it becomes easier to block water (water droplets, etc.) moving towards the adhesive area.

[0051] <Third variation> Referring to Figure 5, a glass diaphragm module 40 according to a third modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those of the above embodiment, and their detailed descriptions will be omitted.

[0052] As shown in Figure 5, the waterproof section 48 provided in the glass diaphragm module 40 according to this modified example has a left waterproof section 48A and a right waterproof section 48B provided to the right of the left waterproof section 48A. The left waterproof section 48A and the right waterproof section 48B are spaced apart in the width direction and are arranged in a straight line along the width direction.

[0053] <Fourth variation> Referring to Figure 6, a glass diaphragm module 50 according to a fourth modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those of the above embodiment, and their detailed descriptions will be omitted.

[0054] As shown in Figure 6, the waterproof section 58 provided in the glass diaphragm module 50 according to this modified example comprises a left waterproof section 58A, a right waterproof section 58B provided to the right of the left waterproof section 58A, and an upper waterproof section 58C provided above the left waterproof section 58A and the right waterproof section 58B. The left waterproof section 58A and the right waterproof section 58B are spaced apart in the width direction and are arranged in a straight line along the width direction. The upper waterproof section 58C is provided to cover the gap between the left waterproof section 58A and the right waterproof section 58B from above.

[0055] <Fifth variation> Referring to Figure 7, a glass diaphragm module 60 according to a fifth modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those of the above embodiment, and their detailed descriptions will be omitted.

[0056] As shown in Figure 7, the waterproof section 68 provided in the glass diaphragm module 60 according to this modified example comprises a left waterproof section 68A, a right waterproof section 68B provided to the right of the left waterproof section 68A, and a lower waterproof section 68C provided below the left waterproof section 68A and the right waterproof section 68B. The left waterproof section 68A and the right waterproof section 68B are arranged side by side in the width direction. The lower waterproof section 68C is provided so as to cover the gap between the left waterproof section 68A and the right waterproof section 68B from below.

[0057] <Sixth variation> Referring to Figure 8, a glass diaphragm module 70 according to a sixth modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components similar to those of the above embodiment, and their detailed descriptions will be omitted.

[0058] As shown in Figure 8, the waterproof portion 78 provided in the glass diaphragm module 70 according to this modified example has a first extended portion 78A that extends in the width direction, and a second extended portion 78B that bends from the end of the first extended portion 78A in the width direction and extends downward.

[0059] In this way, by providing the waterproof portion 78 with a second extending portion 78B that extends vertically, water moving from the left and right directions toward the adhesive portion 16 can also be blocked. Therefore, water is less likely to come into contact with the adhesive portion 16, and thus deterioration of the adhesive portion 16 can be further suppressed.

[0060] <7th variation> Referring to Figure 9, a glass diaphragm module 80 according to the seventh modification of the above embodiment will be described. In this modification, the configuration of the waterproof section differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as those in the above embodiment, and their detailed descriptions will be omitted.

[0061] As shown in Figure 9, the waterproof portion 88 provided in the glass diaphragm module 80 according to this modified example has a first extending portion 88A that extends in the width direction, a second extending portion 88B that bends from the left end of the first extending portion 88A in the width direction and extends to the left and downward in the width direction, and a third extending portion 88C that bends from the right end of the first extending portion 88A in the width direction and extends to the right and downward in the width direction.

[0062] In this way, by providing the second extended portion 88B and the third extended portion 88C extending vertically in the waterproof portion 88 on both the left and right sides, water moving from the left and right directions toward the adhesive portion 16 can be blocked more effectively. Therefore, water is less likely to come into contact with the adhesive portion 16, and thus deterioration of the adhesive portion 16 can be further suppressed.

[0063] <8th variation> Referring to Figure 10, a glass diaphragm module 90 according to the eighth modification of the above embodiment will be described. In this modification, the configuration of the waterproof part and the adhesive part differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as those in the above embodiment, and their detailed descriptions will be omitted.

[0064] As shown in Figure 10, the waterproof section 98 provided in the glass diaphragm module 90 according to this modified example includes a first waterproof section 98A, a second waterproof section 98B provided to the right of the first waterproof section 98A, and a third waterproof section 98C provided to the right of the second waterproof section 98B. The first waterproof section 98A, the second waterproof section 98B, and the third waterproof section 98C are spaced apart in the width direction. Furthermore, the first waterproof section 98A, the second waterproof section 98B, and the third waterproof section 98C are arranged in a straight line along the width direction.

[0065] Furthermore, the adhesive portion 96 provided in the glass diaphragm module 90 according to this modified example is provided in two, arranged vertically. Each adhesive portion 96 has a first adhesive portion 96A, a second adhesive portion 96B provided to the right of the first adhesive portion 96A, and a third adhesive portion 96C provided to the right of the second adhesive portion 96B. The first adhesive portion 96A, the second adhesive portion 96B, and the third adhesive portion 96C are spaced apart in the width direction. In addition, the first adhesive portion 96A, the second adhesive portion 96B, and the third adhesive portion 96C are arranged in a straight line along the width direction.

[0066] The first adhesive portion 96A, the second adhesive portion 96B, and the third adhesive portion 96C are provided below the first waterproof portion 98A, the second waterproof portion 98B, and the third waterproof portion 98C, respectively. Specifically, the first adhesive portion 96A is provided so as to overlap with the first waterproof portion 98A when viewed from above. Similarly, the second adhesive portion 96B is provided so as to overlap with the second waterproof portion 98B when viewed from above. The third adhesive portion 96C is provided so as to overlap with the third waterproof portion 98C when viewed from above.

[0067] <9th variation> Referring to Figure 11, a glass diaphragm module 100 according to a ninth modification of the above embodiment will be described. In this modification, the configuration of the adhesive portion differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as those in the above embodiment, and their detailed descriptions will be omitted.

[0068] As shown in Figure 11, the adhesive portion 106 provided on the glass diaphragm module 100 according to this modified example has a pair of vertical adhesive portions 106A whose longitudinal direction is aligned with the vertical direction, and a horizontal adhesive portion 106B provided below the pair of vertical adhesive portions 106A whose longitudinal direction is aligned with the width direction. The pair of vertical adhesive portions 106A are spaced apart in the width direction. The pair of vertical adhesive portions 106A and the horizontal adhesive portion 106B are covered from above by a waterproof portion 18. The vertical adhesive portion 106A is curved such that its central portion in the width direction is located above the end portion.

[0069] In the modified glass vibration module 100, the vertical adhesive portion 106 is provided so that its longitudinal direction is vertical. This reduces the contact area between the vertical adhesive portion 106 and water moving from top to bottom. Therefore, water is less likely to come into contact with the vertical adhesive portion 106, and thus the deterioration of the vertical adhesive portion 106 can be further suppressed.

[0070] Furthermore, in the modified glass vibration module 100, the upper end of the vertical adhesive portion 106 is curved such that the central part in the width direction is located above the end. As a result, water that comes into contact with the upper end of the vertical adhesive portion 106 flows towards the end and then downward from the end. In this way, water does not accumulate on the vertical adhesive portion 106, so the contact time between the water and the vertical adhesive portion 106 can be shortened. Therefore, deterioration of the vertical adhesive portion 106 can be further suppressed.

[0071] Furthermore, in the glass vibration module 100 according to this modified example, the pair of vertical adhesive portions 106 are spaced apart in the width direction. Therefore, water flows downward through the gap provided between the vertical adhesive portions 106. In this way, water does not accumulate on the vertical adhesive portions 106, so the contact time between the water and the vertical adhesive portions 106 can be shortened. Therefore, deterioration of the vertical adhesive portions 106 can be further suppressed.

[0072] <10th variation> Referring to Figure 12, a glass diaphragm module 110 according to a tenth modification of the above embodiment will be described. In this modification, the configuration of the adhesive part and the waterproof part differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as in the above embodiment, and their detailed descriptions will be omitted.

[0073] As shown in Figure 12, the waterproof section 118 provided in the glass diaphragm module 110 according to this modified example has an upper waterproof section 118A and a lower waterproof section 118B provided below the upper waterproof section 118A. The upper waterproof section 118A and the lower waterproof section 118B are arranged side by side in the vertical direction. The upper waterproof section 118A and the lower waterproof section 118B are provided substantially parallel to each other. The widthwise length of the upper waterproof section 118A is shorter than the widthwise length of the lower waterproof section 118B. The upper waterproof section 118A is provided at the upper end of the vibrating section 14. The lower waterproof section 118B is provided in the vertical center of the vibrating section 14. In addition, the adhesive section 116 provided in the glass diaphragm module 110 according to this modified example is provided below the lower waterproof section 118B.

[0074] <11th variation> Referring to Figure 13, a glass diaphragm module 120 according to the 11th modification of the above embodiment will be described. In this modification, the configuration of the adhesive part and the waterproof part differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as those of the above embodiment, and their detailed descriptions will be omitted.

[0075] As shown in Figure 13, the waterproof portion 128 provided on the glass diaphragm module 120 according to this modified example is formed in an annular shape along the outer circumference of the vibrating portion 14. The adhesive portion 126 provided on the glass diaphragm module 120 according to this modified example is provided inside the annular waterproof portion 128. That is, the waterproof portion 128 surrounds the adhesive portion 126 from its entire circumferential direction.

[0076] In the modified glass vibration module 120, the waterproof portion 128 surrounds the adhesive portion 126. This makes it easier for the waterproof portion 128 to block water droplets moving along the rear glass 12 toward the adhesive portion 126. Therefore, water is less likely to come into contact with the adhesive portion 126, thus further suppressing the deterioration of the adhesive portion 126.

[0077] <12th variation> Referring to Figure 14, a glass diaphragm module 130 according to the 12th modification of the above embodiment will be described. In this modification, the configuration of the adhesive part and the waterproof part differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as in the above embodiment, and their detailed descriptions will be omitted.

[0078] As shown in Figure 14, the waterproof portion 138 provided on the glass diaphragm module 130 in this modified example is provided along the upper half of the outer circumference of the vibrating portion 14. In addition, the adhesive portion 136 provided on the glass diaphragm module 120 in this modified example is provided along the lower half of the outer circumference of the vibrating portion 14.

[0079] <13th variation> Referring to Figures 15 and 16, a glass diaphragm module 140 according to the 13th modification of the above embodiment will be described. In this modification, the configuration of the vibrating part differs from that of the above embodiment. Since the other configurations are the same as those of the above embodiment, only the differences from the above embodiment will be described below, and the same reference numerals will be used for components that are the same as those of the above embodiment, and their detailed descriptions will be omitted.

[0080] As shown in Figure 16, the vibrating section 144 provided in the glass diaphragm module 140 according to this modified example has an opposing surface 144B that faces the glass plate and a back surface 144C that is the opposite side of the opposing surface 144B. In addition, the vibrating section 144 has a plurality of through holes 144A that connect the opposing surface 144B and the back surface 144C.

[0081] As shown in Figure 15, the through-holes 144A are provided so as to overlap with the adhesive portion 16 when viewed from above. Each adhesive portion 16 has two overlapping through-holes 144A. The two through-holes 144A are spaced apart in the width direction. Air is conducted through the through-holes 144A.

[0082] In the modified diaphragm module 140, a through hole 144A is formed in the vibrating part 144. This allows air to be introduced into the adhesive part 16 through the through hole 144A. Therefore, for example, if the adhesive part 16 is made of a material that hardens upon contact with air, the adhesive part 16 can be hardened more effectively. Thus, the rear glass 12 and the vibrating part 144 can be bonded more firmly. Furthermore, since the through-hole 144A is provided so as to overlap with the adhesive portion 16, it is easier to bring air into contact with the adhesive portion 16. Therefore, the adhesive portion 16 can be cured more effectively.

[0083] <14th variation> Referring to Figure 17, a glass diaphragm module 150 according to the 14th modified example of the above embodiment will be described. In this modified example, the position of the through-hole formed in the vibrating part is different from that of the 13th modified example. Since the other configurations are the same as those of the 13th modified example, only the differences from the 13th modified example will be described below, and the same reference numerals will be used for components similar to those in the 13th modified example, and their detailed descriptions will be omitted.

[0084] As shown in Figure 17, the vibrating portion 154 provided in the glass diaphragm module 150 according to this modified example has through holes 154A provided so as not to overlap with the adhesive portion 16 when viewed from the top and bottom. Each through hole 154A is provided between adhesive portions 16 that are spaced apart in the vertical direction.

[0085] In the modified diaphragm module 150, the through-hole 154A is provided so as not to overlap with the adhesive portion 16. As a result, air is introduced between the rear glass 12 and the vibrating portion 150 through the through-hole 154A. Therefore, the entire adhesive portion 16 provided between the rear glass 12 and the vibrating portion 150 is more easily brought into contact with the air. Thus, for example, if the adhesive portion 16 is made of a material that hardens upon contact with air, the entire adhesive portion 16 can be hardened more effectively. Therefore, the rear glass 12 and the vibrating portion 150 can be bonded more firmly.

[0086] <15th variation> Referring to Figure 18, a glass diaphragm module 160 according to the 15th modified example of the above embodiment will be described. In this modified example, the shape of the through-hole formed in the vibrating part is different from that of the 13th modified example. Since the other configurations are the same as those of the 13th modified example, only the differences from the 13th modified example will be described below, and the same reference numerals will be used for components similar to those in the 13th modified example, and their detailed descriptions will be omitted.

[0087] As shown in Figure 18, the vibrating portion 164 provided in the glass diaphragm module 160 according to this modified example is provided with a slit-shaped through hole 164A extending in the width direction. Each adhesive portion 16 is provided with one overlapping through hole 164A.

[0088] <16th variation> Referring to Figure 19, a glass diaphragm module 170 according to the 16th modified example of the above embodiment will be described. In this modified example, the shape of the through-hole formed in the vibrating part differs from that of the 13th modified example. Since the other configurations are the same as those of the 13th modified example, only the differences from the 13th modified example will be described below, and the same reference numerals will be used for components similar to those in the 13th modified example, and their detailed descriptions will be omitted.

[0089] As shown in Figure 19, the vibrating portion 174 provided in the glass diaphragm module 170 according to this modified example is provided with a slit-shaped through-hole 174A extending in the vertical direction. Multiple through-holes 174A are provided in each adhesive portion 16 so as to overlap. The multiple through-holes 174A are arranged in a line at predetermined intervals in the direction in which the adhesive portion 16 extends.

[0090] <17th variation> Referring to Figure 20, a glass diaphragm module 180 according to the 17th modified example of the above embodiment will be described. In this modified example, the shape and position of the through holes formed in the vibrating part differ from those of the 13th modified example. Since the other configurations are the same as those of the 13th modified example, only the differences from the 13th modified example will be described below, and the same reference numerals will be used for components similar to those in the 13th modified example, and their detailed descriptions will be omitted.

[0091] As shown in Figure 20, the vibrating portion 184 provided in the glass diaphragm module 180 according to this modified example includes a slit-shaped through hole 184A that completely overlaps with the adhesive portion 16, a circular through hole 184B that completely overlaps with the adhesive portion 16, a circular through hole 184C that partially overlaps with the adhesive portion 16, and a slit-shaped through hole 184D that spans multiple adhesive portions 16. In this way, various shapes of through holes may be combined.

[0092] Although a glass diaphragm module according to an embodiment has been described above, the present invention can be modified as appropriate without departing from its essence. For example, the above embodiment describes an example in which the glass diaphragm module 10 is applied to the rear glass 12, but the present invention is not limited thereto. For example, the glass diaphragm module may be applied to other vehicle windows (such as side windows or roof windows).

[0093] Specifically, when a glass diaphragm module is applied to window glass such as the rear glass 12 or side glass, where the main surface is approximately a vertical plane, the waterproof portion is provided above the adhesive portion, as described in the above embodiment and in each figure.

[0094] Next, referring to Figure 21, we will explain the case where the glass diaphragm module 190 is applied to window glass such as roof glass, where the main surface is approximately horizontal. In the example in Figure 21, the vibrating part 194 is attached to the roof glass (glass plate) 192. As shown in Figure 21, if the main surface of such roof glass 192 is not a perfect horizontal plane (in other words, if it has even a slight angle with respect to the horizontal plane), then the concept of up and down arises for the roof glass 192. That is, in the example in Figure 21, the front side (left side of the paper) of the roof glass 192 is located above the rear side (right side of the paper). Therefore, even with roof glass 192, it is possible to provide the waterproof part 198 above the adhesive part 196. By providing the waterproof part 198 in this way, the waterproof part 198 can block water droplets (see arrow W) flowing from top to bottom along the roof glass 192. Therefore, it is possible to make it difficult for water to come into contact with the adhesive part 196, and the deterioration of the adhesive part 196 can be suppressed.
