Description

Glass diaphragm module

[0001] The present disclosure relates to a glass diaphragm module.

[0002] In recent years, technologies for making a glass plate function as a speaker by vibrating the glass plate have been studied. Japanese Patent Application Laid-Open No. 2023-152832 discloses a glass diaphragm with a vibrator, including a glass laminate including a first glass plate, a plate-like body, and an intermediate film positioned between the first glass plate and the plate-like body, a mount portion for fixing the vibrator to the glass laminate, and a vibrator for generating vibrations.

[0003] By the way, a glass diaphragm may be exposed to sunlight, such as when it is installed outdoors. When the glass diaphragm is exposed to sunlight, solar energy passes through the glass plate and is transmitted to the vibration components attached to the glass plate. When solar energy is transmitted to the vibration components, the vibration components become hot, which may cause malfunction or damage.

[0004] In consideration of the above facts, an object of the present disclosure is to obtain a glass diaphragm module that can suppress the temperature rise of vibration components and suppress malfunction or damage of the vibration components.

[0005] The glass diaphragm module according to the present disclosure includes a glass plate that constitutes a window glass separating an interior and an exterior, and vibration components attached to the surface of the glass plate on the interior side for vibrating the glass plate, and the total solar transmittance of the glass plate is 50% or less.

[0006] As described above, the glass diaphragm module according to the present disclosure has an excellent effect of suppressing the temperature rise of vibration components and suppressing malfunction or damage of the vibration components.

[0008] Hereinafter, preferred embodiments of the glass diaphragm module according to the embodiment will be described 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 this disclosure may be applied to other moving objects such as airplanes, helicopters, ships, and trains, not just vehicles. Furthermore, the glass diaphragm module according to this disclosure may be applied to the windows of buildings and other structures.

[0009] First, the glass diaphragm module 100 according to the first embodiment will be described with reference to Figure 1.

[0010] In this embodiment, for example, the glass diaphragm module 100 is applied to the roof glass 10 of a vehicle. As shown in Figure 1, the glass diaphragm module 100 comprises a roof glass (glass plate) 10, a vibrator (vibrating component) 19 that vibrates the roof glass 10 to function as a speaker, a mounting member 18 provided between the roof glass 10 and the vibrator 19, and an adhesive layer 17 that bonds the mounting member 18 and the roof glass 10.

[0011] (Roof Glass) The roof glass 10 constitutes the vehicle's window glass. The roof glass 10 separates the interior space S1 from the exterior space S2. The roof glass 10 is fixed to the vehicle body in a state where it cannot slide. The roof glass 10 may be single-pane glass or laminated glass in which two glass plates are bonded together with a resin intermediate layer. The roof glass 10 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.

[0012] If the roof glass 10 is inorganic glass and single-pane glass, it is preferable that the roof glass 10 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.

[0013] In the case of laminated glass in which the roof glass 10 is made of two glass plates 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.

[0014] The roof glass 10 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.

[0015] When the roof glass 10 is single-pane glass, the thickness of the roof glass 10 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 roof glass 10, making it easier for the piston to vibrate. Also, when the roof glass 10 is single-pane glass, from the viewpoint of reducing the weight of the glass diaphragm module 100, the thickness of the roof glass 10 is preferably 10.0 [mm] or less, more preferably 7.0 [mm] or less, and even more preferably 5.0 [mm] or less.

[0016] When the roof glass 10 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 roof glass 10 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 roof glass 10 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 roof glass 10 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 100, it is preferably 10.0 [mm] or less, more preferably 8.0 [mm] or less, and even more preferably 6.0 [mm] or less.

[0017] When the roof glass 10 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. Furthermore, materials to enhance sound insulation, increase rigidity, and absorb ultraviolet and infrared rays may be added to the intermediate layer. The intermediate layer may also be in liquid or gel form. 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, fluorinated solvents, fluorinated 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, fluorinated, 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 copolymer resins thereof. Alternatively, composite materials combining the above materials may be used. 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 roof glass 10 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 may 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.

[0018] In this embodiment, the roof glass 10 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 roof glass 10, 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 this disclosure may also be applied to structures without a light-shielding layer.

[0019] The roof glass 10 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 roof glass 10, but there may be areas where the light-shielding layer is not provided in at least a part of it.

[0020] Furthermore, a defogger (not shown) may be formed on the interior surface of the roof glass 10 to clear fog (for anti-fogging). The defogger has a plurality of heater wires extending in the width direction of the roof glass 10 and a pair of busbars extending vertically near both sides of the roof glass 10, 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 roof glass 10.

[0021] Furthermore, if the roof glass 10 is equipped with conductive wires (for example, defoggers and antennas) formed by printing and baking a paste containing a conductive metal (for example, silver paste) onto the main surface on the interior side of the vehicle, it is preferable that the transducer 19 be mounted so as not to overlap with the conductive wires.

[0022] Furthermore, a coating film may be formed on the roof glass 10. 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.

[0023] Furthermore, the roof glass 10 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 colored glass, and is also called dark gray glass. In the roof glass 10, 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.

[0024] A mounting member 18 is bonded to the main surface of the roof glass 10 on the side facing the interior space S1 of the vehicle using an adhesive layer 17. A vibrator 19 for vibrating the roof glass 10 is attached to the mounting member 18.

[0025] (Vibrator) The vibrator 19 is bonded to the roof glass 10 via a mounting member 18, which will be described later. The vibrator 19 is connected to a power source via a cable (not shown) and is an actuator that vibrates the roof glass 10 in response to an input electrical signal. In this embodiment, the vibrator 19 is, as an example, a voice coil motor including a coil and a magnetic circuit, with one of the coil and magnetic circuit fixed to the roof glass 10 and the other being arranged to move relative to the roof glass 10. When current flows through the coil, vibration is generated by the interaction between the coil and the magnetic circuit, causing the roof glass 10 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 roof glass 10 can be used, such as a piezo actuator or other actuators besides a voice coil motor.

[0026] (Mounting Member) The transducer 19 is fixed to the mounting member 18. The method of fixing the mounting member 18 and the transducer 19 is not particularly limited, and they may be configured to be mechanically attached with bolts, rivets, claws, etc., or they may be attached with adhesive or the like.

[0027] The mounting member 18 may be made of a metal including stainless steel, aluminum, titanium, iron, zinc, aluminum alloy, magnesium alloy, etc., and 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, PPS, PEEK, PET, and POM may be used, or fiber-reinforced plastics including glass fibers or carbon fibers may be used.

[0028] (Adhesive layer) The adhesive layer 17 is provided between the roof glass 10 and the mounting member 18. The adhesive layer 17 adheres the roof glass 10 and the mounting member 18. As the adhesive layer 17, for example, adhesives such as urethane-based, phenol-based, butyl-based, synthetic rubber-based, acrylic-based, epoxy-based, silicone-based, and epoxy-modified silicone-based adhesives can be used, as well as adhesives that are thermosetting, moisture-curing, two-component-curing, ultraviolet-curing, visible-light-curing, or anaerobic-curing. In particular, epoxy-modified silicone-based adhesives that do not contain plasticizers are preferred because they are heat-resistant and have low decomposition properties.

[0029] The thickness of the adhesive layer 17 should be 12 mm or less, preferably 6.0 mm or less, more preferably 3.0 mm or less, more preferably 2.0 mm or less, more preferably 1.2 mm or less, particularly preferably 0.6 mm or less, and even more preferably 0.2 mm or less, as a thinner layer allows for more effective transmission of vibrations from the transducer 19 to the roof glass 10.

[0030] (Total Solar Transmittance) In such a glass diaphragm module 100, the total solar transmittance (Tts) of the roof glass 10 is set to 50% or less. The total solar transmittance is measured in accordance with ISO 13837. The total solar transmittance is defined as the ratio of the amount of heat flowing into the vehicle interior space S1 to the amount of solar energy incident on the roof glass 10, which is set to 1.

[0031] In this way, by setting the total solar radiation transmittance of the roof glass 10 to 50% or less, the heat of the sunlight A that enters the roof glass 10 from the outdoor space S2 is effectively shielded by the glass plate. Specifically, the energy of the sunlight A2 that passes through the roof glass 10 and enters the indoor space S1 of the vehicle is 50% or less of the energy of the sunlight A1 that enters the roof glass 10. The total solar radiation transmittance of the roof glass 10 is preferably 40% or less, more preferably 35% or less, even more preferably 30% or less, even more preferably 25% or less, and particularly preferably 20% or less.

[0032] In this way, the roof glass 10 can reduce the energy of sunlight flowing into the vehicle interior space S1. Therefore, the heat transmitted to the transducer 19 attached to the vehicle interior space S1 side of the roof glass 10 is also reduced. Thus, the temperature rise of the transducer 19 is suppressed, and malfunction or damage to the transducer 19 can be suppressed.

[0033] Furthermore, as a means of suppressing the temperature rise of the transducer 19, the total solar radiation transmittance of the roof glass 10 itself is reduced. In other words, no other devices are provided to suppress the temperature rise of the transducer 19. Therefore, compared to cases where devices to suppress the temperature rise of the transducer 19 are provided, the number of parts can be reduced and the structure can be simplified.

[0034] (Solar reflectance) The roof glass 10 may also have a solar reflectance (Re) of 10% or more in accordance with JIS 3106:2019. In this way, sunlight incident on the roof glass 10 from the exterior space S2 is effectively reflected by the roof glass 10. Therefore, the heat of sunlight flowing into the interior space S1 of the vehicle can be reduced. Consequently, the heat transmitted to the transducer 19 attached to the interior space S1 side of the roof glass 10 is also reduced. Therefore, the temperature rise of the transducer 19 can be suppressed, and malfunction or damage to the transducer 19 can be suppressed. The solar reflectance of the roof glass 10 is preferably 20% or more, more preferably 30% or more, and more preferably 40% or more.

[0035] (Solar transmittance) The roof glass 10 may also have a solar transmittance (Te) of 40% or less. The solar transmittance is measured in accordance with JIS R3106:2019. In this way, sunlight incident on the roof glass 10 from the vehicle exterior space S2 is effectively blocked by the roof glass 10. Therefore, the heat of sunlight flowing into the vehicle interior space S1 can be reduced. As a result, the heat transmitted to the transducer 19 attached to the vehicle interior space S1 side of the roof glass 10 is also reduced. As a result, the temperature rise of the transducer 19 can be suppressed, and malfunction or damage to the transducer 19 can be suppressed. The solar transmittance of the roof glass 10 is preferably 30% or less, more preferably 20% or less, more preferably 10% or less, and more preferably 5% or less.

[0036] [Second Embodiment] Next, a glass diaphragm module according to the second embodiment of the present disclosure will be described with reference to FIG. 2. The glass diaphragm module according to this embodiment has a different roof glass structure from that of the first embodiment. Since the other points are the same, the same components will be denoted by the same reference numerals and detailed description thereof will be omitted.

[0037] The roof glass 20 of the glass diaphragm module 200 according to this embodiment is a laminated glass. As shown in FIG. 2, the roof glass 20 includes an inner glass plate 21 provided on the vehicle interior space S1 side, an outer glass plate 22 provided on the vehicle exterior space S2 side with respect to the inner glass plate 21, and an intermediate layer 23 provided between the inner glass plate 21 and the outer glass plate 22.

[0038] A metal coating is applied to the surface of the inner glass plate 21 on the vehicle interior space S1 side. Hereinafter, the metal coating applied to the surface of the inner glass plate 21 on the vehicle interior space S1 side will be referred to as "inner metal coating 24". A metal coating is also applied to the surface of the outer glass plate 22 on the vehicle interior space S1 side. Hereinafter, the metal coating applied to the surface of the outer glass plate 22 on the vehicle interior space S1 side will be referred to as "outer metal coating 25".

[0039] The inner metal coating 24 is provided between the inner glass plate 21 and the adhesive layer 17. In other words, the mount member 18 is adhered to the inner metal coating 24 by the adhesive layer 17. The outer metal coating 25 is provided between the outer glass plate 22 and the intermediate layer 23.

[0040] The glass plates (inner glass plate 21 and outer glass plate 22), the intermediate layer 23, and the metal coatings (inner metal coating 24 and outer metal coating 25) according to this embodiment may employ the materials described in the first embodiment. Hereinafter, an example of the materials will be described.

[0041] The inner glass plate 21 is made of colored glass (specifically, green glass). The outer glass plate 22 is made of clear glass. The intermediate layer 23 is a colored interlayer. The inner metal coating 24 is a Low-E coating (low-emissivity layer). Specifically, it is a metal coating made of indium tin oxide (ITO). The emissivity of the Low-E coating is preferably 0.8 or less, more preferably 0.5 or less, even more preferably 0.2 or less, and particularly preferably 0.1 or less. The outer metal coating 25 is a heat-reflective coating made of silver.

[0042] This embodiment provides the following effects. In this embodiment, metal coatings (inner metal coating 24 and outer metal coating 25) are applied to the surface of the inner glass plate 21 and the surface of the outer glass plate 22. The outer metal coating 25 is a heat-reflective coating and has heat-reflective properties. The inner metal coating 24 is a Low-E coating and has low-emissivity properties. Therefore, the heat of sunlight incident on the roof glass 20 from the outside space S2 is effectively reflected or absorbed by the metal coatings (inner metal coating 24 and outer metal coating 25) provided on the roof glass 20. As a result, the heat of sunlight flowing into the inside space S1 of the vehicle can be reduced. As a result, the heat transmitted to the transducer 19 attached to the inside space S1 side of the roof glass 20 is also reduced. As a result, the temperature rise of the transducer 19 is suppressed, and malfunctions and damage to the transducer 19 can be suppressed.

[0043] Furthermore, in this embodiment, the inner glass plate 21 is made of colored glass. As a result, the heat of sunlight incident on the roof glass 20 from the exterior space S2 is effectively shielded by the inner glass plate 21. Therefore, the heat of sunlight flowing into the interior space S1 of the vehicle can be reduced. Consequently, the heat transmitted to the transducer 19 attached to the interior space S1 side of the roof glass 20 is also reduced. Therefore, the temperature rise of the transducer 19 is suppressed, and malfunction or damage to the transducer 19 can be suppressed.

[0044] Also, similarly, since the intermediate layer 23 is also a colored intermediate film, the heat of sunlight is effectively blocked by the intermediate layer 23 as well. Therefore, the temperature rise of the vibrator 19 can be suppressed, and malfunctions and damage of the vibrator 19 can be suppressed.

[0045] Also, by configuring it in this way, the total solar energy transmittance Tts can be suitably set to 50% or less.

[0046] Instead of the inner glass plate 21, the outer glass plate 22 may be a colored glass. Even in such a case, similarly, the temperature rise of the vibrator 19 can be suppressed, and malfunctions and damage of the vibrator 19 can be suppressed. Also, in addition to the inner glass plate 21, the outer glass plate 22 may be a colored glass.

[0047] [Modification Example 1] A modification of the second embodiment will be described. In this modification, the material of the members constituting the roof glass 20 is different from that of the second embodiment.

[0048] The inner glass plate 21 according to this modification is a heat ray absorbing glass. The outer glass plate 22 is a clear glass. The intermediate layer 23 is a colored intermediate film having a heat shielding function. The inner metal coating 24 is a Low-E coating. Specifically, it is a metal coating formed of indium tin oxide (ITO: Indium Tin Oxide). The outer metal coating 25 is a heat ray reflecting coating formed of silver.

[0049] In this modification, the inner glass plate 21 is a heat ray absorbing glass. Thereby, since the inner glass plate 21 absorbs the heat of sunlight, the heat of sunlight flowing into the vehicle interior space S1 can be reduced. Therefore, the heat transmitted to the vibrator 19 attached to the vehicle interior space S1 side of the roof glass 20 is also reduced. Therefore, the temperature rise of the vibrator 19 can be suppressed, and malfunctions and damage of the vibrator 19 can be suppressed.

[0050] Furthermore, the intermediate layer 23 has a heat-shielding function. As a result, the intermediate layer 23 blocks the heat of sunlight, reducing the amount of heat from sunlight flowing into the vehicle interior space S1. Therefore, the heat transmitted to the transducer 19 attached to the vehicle interior space S1 side of the roof glass 20 is also reduced. Thus, the temperature rise of the transducer 19 is suppressed, and malfunctions or damage to the transducer 19 can be suppressed.

[0051] Furthermore, this configuration makes it possible to suitably set the total solar radiation transmittance Tts to 50% or less.

[0052] [Third Embodiment] Next, a glass diaphragm module according to the third embodiment of the present disclosure will be described with reference to Figure 3. The glass diaphragm module according to this embodiment differs from the first embodiment in the structure of the roof glass. Since it is the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0053] The roof glass 30 of the glass diaphragm module 300 according to this embodiment is made of laminated glass. As shown in Figure 3, the roof glass 30 has an inner glass plate 31 provided on the side of the vehicle interior space S1, an outer glass plate 32 provided on the side of the vehicle exterior space S2 that is closer to the inner glass plate 31, and an intermediate layer 33 provided between the inner glass plate 31 and the outer glass plate 32.

[0054] The surface of the inner glass plate 31 facing the vehicle interior space S1 is coated with a metal coating. Hereinafter, the metal coating applied to the surface of the inner glass plate 31 facing the vehicle interior space S1 will be referred to as "inner metal coating 34". In this embodiment, the surface of the outer glass plate 32 is not coated with a metal coating.

[0055] The inner metal coating 34 is provided between the inner glass plate 31 and the adhesive layer 17. In other words, the mounting member 18 is bonded to the inner metal coating 34 by the adhesive layer 17.

[0056] The glass plates (inner glass plate 31 and outer glass plate 32), intermediate layer 33, and metal coating (inner metal coating 34) according to this embodiment may be made of the materials described in the first embodiment above. An example of materials will be described below.

[0057] The inner glass plate 31 is made of colored glass (specifically, green glass) or clear glass. Similarly, the outer glass plate 32 is also made of colored glass (specifically, green glass) or clear glass. The intermediate layer 33 is a colored interlayer. The inner metal coating 34 is Low-E coated. Specifically, it is made of indium tin oxide (ITO) or fluorinated tin oxide (SnO) ２ It is said to be a metal coating formed by :F).

[0058] In this embodiment as well, if colored glass is used for at least one of the inner glass plate 31 and the outer glass plate 32, the same effects as in the second embodiment are achieved. Furthermore, since the intermediate layer 33 is a colored intermediate layer, the same effects as in the second embodiment are achieved. In addition, since the inner metal coating 34 is a Low-E coating, the same effects as in the second embodiment are achieved.

[0059] Furthermore, this configuration makes it possible to suitably set the total solar radiation transmittance Tts to 50% or less.

[0060] [Modification 2] A modification of the third embodiment will now be described. In this modification, the material of the component constituting the roof glass 30 is different from that of the third embodiment.

[0061] In this modified example, the inner glass plate 31 is made of colored glass (specifically, green glass) or clear glass. Similarly, the outer glass plate 32 is also made of colored glass (specifically, green glass) or clear glass. The intermediate layer 33 is a colored interlayer with heat-shielding properties. Specifically, the intermediate layer 33 is made of indium tin oxide, antimond-doped tin oxide (ATO), or near-infrared absorbing fine particles (CWO®). The inner metal coating 34 is Low-E coated. Specifically, it is made of indium tin oxide (ITO) or fluorinated tin oxide (SnO). ２ It is said to be a metal coating formed by :F).

[0062] Even with this configuration, the same effects as those described in the first to third embodiments are achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0063] [Modification 3] Another modification of the third embodiment will be described. In this modification, the material of the component constituting the roof glass 30 is different from that of the third embodiment.

[0064] In this modified example, the inner glass plate 31 is made of heat-absorbing glass. Similarly, the outer glass plate 32 is also made of heat-absorbing glass. The intermediate layer 33 is a colored interlayer. The inner metal coating 34 is Low-E coated. Specifically, it is made of indium tin oxide (ITO) or fluorinated tin oxide (SnO). ２ It is said to be a metal coating formed by :F).

[0065] Even with this configuration, the effects described in the first to third embodiments above can be achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0066] [Modification 4] Another modification of the third embodiment will be described. In this modification, the material of the component constituting the roof glass 30 is different from that of the third embodiment.

[0071] The surface of the outer glass plate 42 facing the vehicle interior space S1 is coated with a metal coating.

[0074] This embodiment also achieves the effects described in the first to third embodiments. Furthermore, this configuration makes it possible to suitably set the total solar radiation transmittance Tts to 50% or less.

[0075] [Modification 5] A modification of the fourth embodiment will now be described. In this modification, the material of the component constituting the roof glass 40 is different from that of the fourth embodiment.

[0076] In this modified example, the inner glass plate 41 is made of colored glass (specifically, green glass). The outer glass plate 42 is made of clear glass.

Specifically, the intermediate layer 43 is made of indium tin oxide, antimond-doped tin oxide (ATO), or near-infrared absorbing fine particles (CWO®). The outer metal coating 25 is a heat-reflective coating made of silver.

[0077] Even with this configuration, the same effects as those described in the first to fourth embodiments are achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0078] [Modification 6] Another modification of the fourth embodiment will be described. In this modification, the material of the component constituting the roof glass 40 is different from that of the fourth embodiment.

[0079] In this modified example, the inner glass plate 41 is made of heat-absorbing glass. The outer glass plate 32 is made of clear glass. The intermediate layer 33 is a colored interlayer. The outer metal coating 25 is a heat-reflective coating made of silver.

[0080] Even with this configuration, the effects described in the first to fourth embodiments above can be achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0081] [Modification 7] Another modification of the fourth embodiment will be described. In this modification, the material of the component constituting the roof glass 40 is different from that of the fourth embodiment.

[0082] In this modified example, the inner glass plate 41 is made of privacy glass. The outer glass plate 42 is made of clear glass. The intermediate layer 33 is made of an uncolored, clear interlayer. The outer metal coating 25 is made of a heat-reflective coating made of silver.

[0083] Even with this configuration, the effects described in the first to third embodiments above can be achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0084] [Fifth Embodiment] Next, a glass diaphragm module according to the fifth embodiment of the present disclosure will be described with reference to Figure 5. The glass diaphragm module according to this embodiment differs from the first embodiment in the structure of the roof glass. Since it is the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0085] The roof glass 50 of the glass diaphragm module 500 according to this embodiment is made of laminated glass. As shown in Figure 5, the roof glass 50 has an inner glass plate 51 provided on the side of the vehicle interior space S1, an outer glass plate 52 provided on the side of the vehicle exterior space S2 that is closer to the inner glass plate 51, and an intermediate layer 53 provided between the inner glass plate 51 and the outer glass plate 52.

[0086] The intermediate layer 53 includes an inner intermediate layer 53A that abuts the inner glass plate 51, an outer intermediate layer 53B that abuts the outer glass plate 52, and a film 54C provided between the inner intermediate layer 53A and the outer intermediate layer 53B.

[0087] The surface of the inner glass plate 51 facing the vehicle interior space S1 is coated with a metal coating. Hereinafter, the metal coating applied to the surface of the inner glass plate 51 facing the vehicle interior space S1 will be referred to as "inner metal coating 54". In this embodiment, the surface of the outer glass plate 52 is not coated with a metal coating.

[0088] The inner metal coating 54 is provided between the inner glass plate 51 and the adhesive layer 17. In other words, the mounting member 18 is bonded to the inner metal coating 54 by the adhesive layer 17.

[0089] The glass plates (inner glass plate 51 and outer glass plate 52), intermediate layer 53, and metal coating (inner metal coating 54) according to this embodiment may be made of the materials described in the first embodiment above. An example of materials will be described below.

[0090] The inner glass plate 51 is made of clear glass. Similarly, the outer glass plate 32 is also made of clear glass. The inner intermediate layer 53A of the intermediate layer 53 is a colored interlayer. The outer intermediate layer 53B of the intermediate layer 53 is an uncolored clear interlayer. The film 53C of the intermediate layer 53 is a film with heat-reflective properties. Specifically, it is a film made of nano-laminated PET (polyethylene terephthalate) or a silver-coated PET film. The inner metal coating 34 is Low-E coated. Specifically, it is indium tin oxide (ITO) or fluorinated tin oxide (SnO) ２ It is said to be a metal coating formed by :F).

[0091] Even with this configuration, the effects described in the first to fourth embodiments above can be achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0092] In this embodiment, the intermediate layer 53 includes a film 53C that has a heat-reflective function. As a result, the heat of sunlight incident on the roof glass 50 from the outside space S2 is effectively reflected by the film 53C provided on the intermediate layer 53. Therefore, the heat of sunlight flowing into the inside space S1 of the vehicle can be reduced. Consequently, the heat transmitted to the transducer 19 attached to the inside space S1 side of the roof glass 50 is also reduced. Therefore, the temperature rise of the transducer 19 can be suppressed, and malfunction or damage to the transducer 19 can be suppressed.

[0093] [Sixth Embodiment] Next, a glass diaphragm module according to the sixth embodiment of the present disclosure will be described with reference to Figure 6. The glass diaphragm module according to this embodiment differs from the first embodiment in the structure of the roof glass. Since it is the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0094] The roof glass 60 of the glass diaphragm module 600 according to this embodiment is made of laminated glass. As shown in Figure 6, the roof glass 60 has an inner glass plate 61 provided on the side of the vehicle interior space S1, an outer glass plate 62 provided on the side of the vehicle exterior space S2 that is closer to the inner glass plate 61, and an intermediate layer 63 provided between the inner glass plate 61 and the outer glass plate 62.

[0095] The intermediate layer 63 includes an inner intermediate layer 63A that abuts the inner glass plate 61, an outer intermediate layer 63B that abuts the outer glass plate 62, and a film 64C provided between the inner intermediate layer 63A and the outer intermediate layer 63B.

[0096] The inner glass panel 61 has a metal coating on the surface facing the vehicle interior space S1. Hereinafter, the metal coating applied to the surface of the inner glass panel 61 facing the vehicle interior space S1 will be referred to as the "inner metal coating 64". The outer glass panel 62 also has a metal coating on the surface facing the vehicle interior space S1. Hereinafter, the metal coating applied to the surface of the outer glass panel 62 facing the vehicle interior space S1 will be referred to as the "outer metal coating 65".

[0097] The inner metal coating 64 is provided between the inner glass plate 61 and the adhesive layer 17. In other words, the mounting member 18 is bonded to the inner metal coating 64 by the adhesive layer 17. The outer metal coating 65 is provided between the outer glass plate 62 and the intermediate layer 63.

[0098] The glass plates (inner glass plate 61 and outer glass plate 62), intermediate layer 63, and metal coatings (inner metal coating 64 and outer metal coating 65) according to this embodiment may be made of the materials described in the first embodiment above. An example of materials will be described below.

[0099] The inner glass plate 61 is made of clear glass. Similarly, the outer glass plate 62 is also made of clear glass. The inner intermediate layer 63A of the intermediate layer 63 is a colored interlayer. The outer intermediate layer 63B of the intermediate layer 63 is an uncolored clear interlayer. The film 63C of the intermediate layer 63 is a dimmable film whose transmittance changes when a voltage is applied. The inner metal coating 64 is a Low-E coating. Specifically, it is made of indium tin oxide (ITO) or fluorinated tin oxide (SnO) ２ The outer metal coating 65 is said to be a metal coating formed of F).

[0100] Even with this configuration, the effects described in the first to fourth embodiments above can be achieved. Furthermore, with this configuration, the total solar radiation transmittance Tts can be preferably set to 50% or less.

[0101] Furthermore, the intermediate layer includes a light-adjusting film that changes its transmittance when a voltage is applied. This allows, for example, the transmittance of the glass plate to be increased when sunlight is strong, thereby suppressing the temperature rise of the vibrating components and preventing malfunctions or damage to the vibrating components.

[0102] [Seventh Embodiment] Next, a glass diaphragm module according to the seventh embodiment of the present disclosure will be described with reference to Figure 7. The glass diaphragm module according to this embodiment differs from the first embodiment in the structure of the roof glass. Since it is the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0103] In this embodiment, the roof glass 70 of the glass diaphragm module 700 has a light-shielding layer 71 attached to the surface facing the vehicle interior space S1. The light-shielding layer 71 has discontinuous portions 72 that are discontinuous from each other in at least a portion of it.

[0104] In the discontinuous section 72, the roof glass 70 is exposed. Therefore, the emissivity of the discontinuous section 72 is lower than that of the black light-shielding layer 71. The surface of the discontinuous section 72 on the side facing the vehicle interior space S1 may be coated with a Low-E coating.

[0105] An adhesive layer 17 is bonded to the lower surface of the light-shielding layer 71. The adhesive layer 17 is bonded to the mounting member 18. The discontinuous portion 72 overlaps with the mounting member 18 and the vibrator 19 when viewed from the stacking direction.

[0106] According to this embodiment, the transducer 19 is provided so as to straddle the light-shielding layer 71 and the discontinuity 72. Generally, the black light-shielding layer 71 has high emissivity. That is, the discontinuity 72 has lower emissivity than the light-shielding layer 71. As a result, a part of the transducer 19 overlaps with the discontinuity 72, which has lower emissivity than the light-shielding layer 71. Therefore, compared to the case where the entire transducer 19 overlaps with the light-shielding layer 71, the radiant heat transmitted from the roof glass 70 and the light-shielding layer 71 can be reduced. In particular, the radiant heat from the region overlapping with the transducer 19 can be reduced. Thus, the temperature rise of the transducer 19 can be suppressed, and malfunctions and damage to the transducer 19 can be suppressed.

[0107] Furthermore, when viewed from above, a discontinuity 72 may also be provided in the region adjacent to the transducer 19. This reduces radiant heat from the region adjacent to the transducer 19. Thus, it is possible to suppress the temperature rise of the transducer 19 and prevent malfunction or damage to the transducer 19. [Eighth Embodiment (Modification of the Seventh Embodiment)] Next, a glass diaphragm module according to the eighth embodiment of the present disclosure will be described with reference to Figure 8. The structure of the roof glass of the glass diaphragm module according to this embodiment differs from that of the first embodiment. Since they are the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0108] In this embodiment, the roof glass 70 of the glass diaphragm module 700 has a light-shielding layer 71 attached to the surface facing the vehicle interior space S1. The light-shielding layer 71 has discontinuous portions 72 that are discontinuous from each other in at least a portion of it.

[0109] In the discontinuous section 72, the roof glass 70 is exposed. Therefore, the emissivity of the discontinuous section 72 is lower than that of the black light-shielding layer 71. The surface of the discontinuous section 72 on the side facing the vehicle interior space S1 may be coated with a Low-E coating.

[0110] An adhesive layer 17 is bonded to the lower surface of the light-shielding layer 71. The adhesive layer 17 is bonded to the mounting member 18. The discontinuous portion 72 does not overlap with the mounting member 18 and the transducer 19 when viewed from the stacking direction. That is, the discontinuous portion 72 is located in the vicinity of the transducer 19.

[0111] In this embodiment, the transducer 19 is positioned to straddle the vicinity of the discontinuity 72. Generally, the black light-shielding layer 71 has high emissivity. That is, the discontinuity 72 has lower emissivity than the light-shielding layer 71. This reduces radiant heat from the region adjacent to the transducer 19. Therefore, it is possible to suppress the temperature rise of the transducer 19 and prevent malfunction or damage to the transducer 19. Furthermore, since the transducer 19 and the discontinuity 72 do not overlap in a plan view, the discontinuity 72 can also serve as a guide to indicate the mounting position of the transducer 19, which is preferable.

[0112] Furthermore, a discontinuity 72 may also be provided in the region that overlaps with the transducer 19 when viewed from above. In this case, the radiant heat transmitted from the roof glass 70 and the light-shielding layer 71 can be reduced. More specifically, the radiant heat from the region that overlaps with the transducer 19 can be reduced. Therefore, the temperature rise of the transducer 19 can be suppressed, and malfunctions or damage to the transducer 19 can be suppressed.

[0113] [Ninth Embodiment] Next, a glass diaphragm module according to the ninth embodiment of the present disclosure will be described with reference to Figure 7. The glass diaphragm module according to this embodiment differs from the first embodiment in the structure of the roof glass. Since it is the same in other respects, the same reference numerals are used for the same components and their detailed descriptions are omitted.

[0114] In this embodiment, the roof glass 80 of the glass diaphragm module 800 has a plurality of black light-shielding layers attached to the surface facing the vehicle interior space S1. The plurality of black light-shielding layers include a first light-shielding layer 81 to which the mounting member 18 is bonded, and a second light-shielding layer 82 provided so as to be spaced apart from the first light-shielding layer 81. The plurality of black light-shielding layers also include a third light-shielding layer 83 provided so as to be spaced apart on the opposite side from the first light-shielding layer 81 and the second light-shielding layer 82, and a fourth light-shielding layer 84 provided so as to be spaced apart on the opposite side from the second light-shielding layer 82 and the first light-shielding layer 81.

[0115] The roof glass 80 is exposed between each black light-shielding layer. Therefore, a first exposed portion 80A is provided between the first light-shielding layer 81 and the second light-shielding layer 82. Similarly, a second exposed portion 80B is provided between the first light-shielding layer 81 and the third light-shielding layer 83, and a third exposed portion 80C is provided between the second light-shielding layer 82 and the fourth light-shielding layer 84. Each exposed portion has a lower emissivity than the black light-shielding layer. A Low-E coating may be applied to the surface of each exposed portion facing the vehicle interior space S1.

[0116] A first adhesive layer 86 is bonded to the lower surface of the first light-shielding layer 81. A second adhesive layer 87 is bonded to the lower surface of the second light-shielding layer 82. The first adhesive layer 86 and the second adhesive layer 87 are spaced apart.

[0117] The first adhesive layer 86 and the second adhesive layer 87 are bonded to the mounting member 18. The mounting member 18 is provided so as to straddle the first adhesive layer 86 and the second adhesive layer 87. Furthermore, the mounting member 18 and the transducer 19 are provided so as to straddle the first light-shielding layer 81 and the second light-shielding layer 82.

[0118] The first exposed portion 80A, when viewed from the vertical direction, overlaps entirely with the mounting member 18 and the transducer 19. The second exposed portion 80B and the third exposed portion 80C, when viewed from the stacking direction, do not overlap with the mounting member 18 and the transducer 19.

[0119] In this embodiment, the transducer 19 is provided so as to straddle the first light-shielding layer 81 and the second light-shielding layer 82. Generally, black light-shielding layers have high emissivity. The roof glass 80 (in other words, the first exposed portion 80A) located between the first light-shielding layer 81 and the second light-shielding layer 82 has lower emissivity than the first light-shielding layer 81 and the second light-shielding layer 82. As a result, a portion of the transducer 19 overlaps with the first exposed portion 80A, which has lower emissivity than the black light-shielding layer. Therefore, compared to the case where the entire transducer 19 is provided so as to overlap with the black light-shielding layer, the radiant heat transmitted from the roof glass 80 and the black light-shielding layer can be reduced. In particular, the radiant heat R1 from the region overlapping with the transducer 19 can be reduced. Thus, the temperature rise of the transducer 19 can be suppressed, and malfunctions and damage to the transducer 19 can be suppressed.

[0120] Furthermore, when viewed from above, exposed portions (second exposed portion 80B and third exposed portion 80C) are also provided in the region adjacent to the transducer 19. Therefore, the radiant heat R2 from the region adjacent to the transducer 19 can also be reduced. Thus, the temperature rise of the transducer 19 can be suppressed, and malfunctions and damage to the transducer 19 can be suppressed.

[0121] Although the glass diaphragm module according to the embodiment has been described above, the design of this disclosure can be modified as appropriate without departing from its essence.

[0122] For example, the intermediate layer described in each of the above embodiments may contain a light-absorbing material. Carbon black is an example of a light-absorbing material. Alternatively, a coloring pigment may be used as the light-absorbing material. The coloring pigment is not particularly limited as long as it can be used for plastics, but examples include organic coloring pigments such as azo, phthalocyanine, quinacridone, perylene, perinone, dioxazine, anthraquinone, and isoindolino, as well as inorganic coloring pigments such as oxides, hydroxides, sulfides, chromic acid, sulfates, carbonates, silicates, phosphates, arsenates, ferrocyanides, carbon, and metal powders. These coloring pigments may be used alone or in combination of two or more types. By including a light-absorbing material in the intermediate layer in this way, sunlight entering the roof glass from the outside space S2 is effectively absorbed by the intermediate layer. Therefore, the heat of sunlight flowing into the inside space S1 can be reduced. Consequently, the heat transmitted to the transducer 19 attached to the inside space S1 side of the roof glass is also reduced. Therefore, the temperature rise of the transducer 19 can be suppressed, and malfunctions and damage to the transducer 19 can be prevented.

[0123] Furthermore, for example, the visible light transmittance of the roof glass described in each of the above embodiments may be set to 30% or less. The visible light transmittance is measured in accordance with JIS R3106:2019. This makes it difficult to see into the vehicle interior space S1 from the vehicle exterior space S2. Consequently, the transducer 19 attached to the vehicle interior space S1 side of the roof glass also becomes difficult to see from the vehicle exterior space S2. Thus, the aesthetic appeal can be improved. The visible light transmittance of the roof glass 10 is preferably 20% or less, more preferably 10% or less, and more preferably 5% or less.

[0124] Furthermore, although the glass diaphragm modules according to each embodiment described above have been explained as being applied to the roof glass located on the upper side of the vehicle, the invention is not limited to this. For example, the glass diaphragm module may be applied to other windows of the vehicle, such as the rear glass located on the rear side of the vehicle, the side windows located on the side doors of the vehicle, or the front windshield located on the front side of the vehicle.

[0125] Furthermore, although the above embodiments describe an example in which the transducer 19 is attached to the mounting member 18 and the mounting member 18 is attached to the roof glass by an adhesive layer 17, this disclosure is not limited thereto. For example, the transducer 19 may be directly bonded to the roof glass by the adhesive layer 17. Alternatively, instead of the mounting member 18, the transducer 19 may be attached to a long rod (not shown). In this case, one end of the rod with the transducer 19 attached is bonded to the roof glass by the adhesive layer 17.

[0126] Furthermore, while the fifth and sixth embodiments described above describe an example in which the film is provided sandwiched between an inner intermediate layer and an outer intermediate layer, the disclosure is not limited thereto. The film may be provided so as to be encapsulated within the intermediate layer.

[0127] Furthermore, a metal coating may be applied to the intermediate layer of each of the above embodiments.
