Description

Technical Field

[0001] The present disclosure relates to a glass vibration plate module. Background Art

[0002] In recent years, technologies have been studied for vibrating a glass plate to function as a speaker. International Publication No. 2022 / 009180 discloses a structure in which a laminated glass having an outer glass layer, an inner glass layer, and an intermediate layer is sealed with a transducer to enable the laminated glass to function as a speaker. In addition, U.S. Patent Application Publication No. 2015 / 0298656 discloses a structure in which a windshield of a vehicle is installed with multiple exciters to enable the windshield to function as a speaker. Japanese Patent Publication No. 2021-180486 discloses a structure in which a sound generator is arranged on a vehicle window glass to vibrate the vehicle window glass and output sound.

[0003] However, in a structure that exhibits a speaker function by vibrating a glass plate as in the above-mentioned Patent Documents 1 to 3, since the vibration of the glass plate is transmitted to the surrounding components fixing the glass plate, unpredictable sounds, i.e., noise, which are different from the sounds originally desired to be produced by the glass plate may be generated, and it is sometimes difficult to produce the original high sound quality. Summary of the invention

[0004] An object of the present disclosure is to realize a glass diaphragm module capable of suppressing the generation of noise which is a component different from the sound generated by vibrating a glass plate structure.

[0005] The glass vibration plate module involved in the present disclosure comprises: a glass vibration plate, comprising a glass plate structure and a vibrator installed on the above-mentioned glass plate structure; a first component, installed on the peripheral end portion of the above-mentioned glass vibration plate via a resin layer; and a second component, configured to be separated from the above-mentioned glass vibration plate and connected to the above-mentioned first component, and the Young's modulus E1 of the above-mentioned first component and the Young's modulus E2 of the above-mentioned second component satisfy E2 / E1≧10.

[0006] In the glass diaphragm module according to the present disclosure, it is possible to suppress the generation of noise which is a component different from the sound generated by vibrating the glass plate structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] <First embodiment>

[0016] A glass diaphragm module 10 according to the first embodiment will be described with reference to the drawings.

[0017] Figure 1 FIG. 1 is a schematic diagram of the glass diaphragm module 10 as viewed from the rear side of the vehicle. Figure 1 As shown, the glass diaphragm module 10 of the present embodiment includes a glass diaphragm 11 , and the glass diaphragm 11 includes a glass plate structure 12 and a vibrator 14 .

[0018] The glass plate structure 12 can be used for vehicle window glass such as windshield, side window glass, rear window glass, rear quarter window glass, front quarter window glass and sunroof glass, but can also be used for applications other than vehicles, such as window glass for railways, airplanes and buildings.

[0019] Figure 1 This is an example in which the glass sheet structure 12 is used as a rear window glass disposed at the rear of a vehicle. Figure 1 In the figure, the X-axis represents the vehicle width direction when the glass plate structure 12 is assembled to the vehicle, and the right side of the vehicle coincides with the positive direction of the X-axis. In addition, the Y-axis represents the vertical direction when the glass plate structure 12 is assembled to the vehicle, and the upper side of the vehicle coincides with the positive direction of the Y-axis.

[0020] Figure 2 It means use Figure 1 The sectional view of the state after the 2-2 line is cut, Figure 2The Z axis represents the front-rear direction of the vehicle when the glass plate structure 12 is assembled to the vehicle. Figure 2 As shown, the glass plate structure 12 is composed of a single plate glass, but may also be composed of a laminated glass. The glass plate structure 12 is formed of transparent or translucent inorganic glass. As inorganic glass, for example, sodium lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass can be used.

[0021] The glass plate structure 12 may be formed of organic glass. Examples of organic glass include PMMA (polymethyl methacrylate) resin, PC (polycarbonate) resin, PS (polystyrene) resin, PET (polyethyleneterephthalate) resin, PVC (polyvinyl chloride) resin, and cellulose resin.

[0022] The thickness of the glass plate structure 12 is preferably 1.0 mm or more, more preferably 2.0 mm or more, and further preferably 3.0 mm or more. This allows the glass plate structure 12 to have sufficient strength as required. In addition, the thickness of the glass plate structure 12 is preferably 7.0 mm or less, more preferably 6.0 mm or less, and further preferably 5.0 mm or less.

[0023] In addition, when the glass plate structure 12 is composed of laminated glass with an intermediate layer sandwiched between a pair of glass plates, the thickness of the pair of glass plates constituting the glass plate structure 12 is preferably 0.1 mm or more, more preferably 0.5 mm or more, and further preferably 1.0 mm or more. In addition, the thickness of the pair of glass plates constituting the glass plate structure 12 may be the same or different.

[0024] For the intermediate layer in the case where the glass plate structure 12 is set as a laminated glass, transparent polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) resin films, silicone (PDMS) resin films, polyurethane resin films, fluorine resin films, polyethylene terephthalate resin films, polycarbonate resin films, etc. containing thermosetting adhesive materials can be exemplified. In addition, materials that improve sound insulation and materials that absorb ultraviolet rays and infrared rays can also be added to the intermediate layer. The thickness of the intermediate layer 18 can be set to, for example, 1.0 nm or more and 1.0 mm or less, 0.1 mm or more and 0.9 mm or less, or 0.2 mm or more and 0.8 mm or less.

[0025] exist Figure 2In the embodiment, the glass sheet structure 12 is formed into a flat plate, but it may be formed into a curved shape. For example, when viewed from the side of the vehicle, the glass sheet structure 12 may be curved so as to bulge toward the rear side of the vehicle.

[0026] A light shielding layer 13 of a predetermined width formed of a black ceramic layer or the like is provided on the outer periphery of the glass vibration plate 11, and a vibrator 14 is arranged so as to overlap with the light shielding layer 13. The vibrator 14 is mounted on the glass plate structure 12 via a mounting portion 16 made of metal or resin. For example, a fixing portion such as a screw may be provided on one of the mounting portion 16 and the vibrator 14, and a threaded hole or the like may be provided on the other of the mounting portion 16 and the vibrator 14, thereby mechanically fastening the vibrator 14 to the mounting portion 16. By mounting the vibrator 14 on the glass plate structure 12 via the mounting portion 16, the vibrator 14 can be easily removed and replaced, but the vibrator 14 may be directly fixed (adhesively) to the glass plate structure 12 without providing the mounting portion 16.

[0027] exist Figure 2 In the example in which the vibrator 14 is mounted on the upper end of the glass plate structure 12, the vibrator 14 may be mounted at other locations. For example, the vibrator 14 may be mounted on the lower end of the glass plate structure 12. In addition, a plurality of vibrators 14 may be mounted on the glass plate structure 12.

[0028] The vibrator 14 is connected to a power source (not shown) and vibrates the glass plate structure 12 according to an input electric signal. As an example, the vibrator 14 of the present embodiment is a voice coil motor including a coil portion and a magnetic circuit, one of which is fixed to the glass plate structure 12, and the other is configured to be relatively movable relative to the glass plate structure 12. Then, by flowing an electric current in the coil portion, vibration is generated by the interaction between the coil portion and the magnetic circuit, and the glass plate structure 12 is vibrated via the mounting portion 16. The vibration direction is the thickness direction of the vibrator 14. However, the vibrator 14 is not limited to a voice coil motor, and an actuator other than a voice coil motor such as a piezoelectric method can be used as long as it is an actuator that can transmit the desired vibration to the glass plate structure 12.

[0029] The first component 18 is installed at the peripheral end of the glass plate structure 12 via the resin layer 20. The resin layer 20 only needs to be continuously provided over a length that is more than half of the total length (full circumferential length) of the peripheral end of the glass plate structure 12. In addition, the continuously provided length is preferably more than 6 / 10, more preferably more than 7 / 10, further preferably more than 8 / 10, preferably more than 9 / 10, and most preferably the full length (full circumferential length) relative to the full circumferential length of the glass plate structure 12. The resin layer 20 of this embodiment is provided over the entire circumference of the peripheral end of the glass plate structure 12. For example, even when the glass plate structure 12 is used for a movable window glass such as a side window glass or a sunroof glass, a structure in which a resin layer such as a rubber or foam material is in contact with the entire circumference of the glass plate structure 12 when it is fully closed can be adopted.

[0030] The resin layer 20 is an adhesive layer for bonding the glass plate structure 12 and the first member 18. The Young's modulus E of the resin layer 20 in this embodiment is R Preferably 1×10 6 Pa~1×10 8 Pa, more preferably 1×10 7 Pa~1×10 8 Pa, more preferably 5×10 7 Pa~1×10 8 Pa.

[0031] The resin layer 20 can be formed to include at least one resin selected from the group consisting of polyurethane, phenol, butyl, synthetic rubber, acrylic, epoxy, silicone, epoxy silicone, and polyvinyl chloride. In addition, a structure in which a primer is pre-disposed on the first component 18, the second component 22, and the glass plate structure 12 can also be adopted. For example, as a body primer and a glass primer, a primer containing at least one of polyol, polyisocyanate, silane coupling agent, carbon black, silica particles, etc. can be used.

[0032] The first component 18 is a first frame body surrounding the glass vibration plate 11. As an example of the first component 18, a tailgate made of resin can be cited. A recessed portion 18A recessed toward the front side of the vehicle is formed in the first component 18, and the glass vibration plate 11 is arranged in a recessed state in the recessed portion 18A. An opening portion 18B is formed in the recessed portion 18A, and the opening portion 18B is blocked by the glass vibration plate 11.

[0033] The first component 18 may be made of general engineering plastics such as ABS, PVC, PC, PP, PBT, PA66, and PPS, or fiber-reinforced plastics including glass fiber or carbon fiber. In addition, a metal reinforcement member or the like may be provided to reinforce the first component 18. In the case where the glass vibration plate module 10 is a resin tailgate using a reinforcement member to reinforce the first component 18, a resin component (resin panel) not shown in the figure may be fixed in a manner of sandwiching the reinforcement member opposite to the first component 18. In addition, the Young's modulus E1 of the first component 18 is preferably 1×10 8 Pa~1×10 11 Pa, more preferably 2×10 8 Pa~5×10 10 Pa, more preferably 5×10 8 Pa~1×10 10 Pa.

[0034] In addition, if Figure 1 and Figure 2 As shown in FIG. 1 , a second member 22 as a second frame body is disposed outside the first member 18. The second member 22 is disposed so as to be separated from the glass vibration plate 11 and connected to the first member 18. Figure 2 In the embodiment, the lower end of the first member 18 overlaps with the surface of the second member 22 on the vehicle rear side. In addition, the sides of the left and right end portions of the first member 18 also overlap with the second member 22 in the same manner (see Figure 1 ).

[0035] like Figure 2 As shown, the upper end of the first member 18 is connected to the second member 22 via a connecting portion 24. The connecting portion 24 includes a fixing member that mechanically fixes the first member 18 and the second member 22. For example, a hinge that swingably connects the first member 18 to the second member 22 can be used as the connecting portion 24.

[0036] Furthermore, the first member 18 and the second member 22 may be bonded together using an adhesive material, or a fastening member such as a bolt and an adhesive material may be combined.

[0037] The second component 22 is composed of metal and may be a metal outer panel of a vehicle. When the first component 18 is a resin tailgate, the second component 22 may be an outer panel of the vehicle supporting the tailgate. Aluminum, iron, stainless steel, etc. may be used as the metal constituting the second component 22.

[0038] The Young's modulus E2 of the second member 22 is preferably 1×10 10 Pa~1×10 12 Pa, more preferably 2×10 10 Pa~5×1011 Pa, more preferably 5×10 10 Pa~1×10 11 Pa.

[0039] Here, when the Young's modulus of the first member 18 is E1 and the Young's modulus of the second member 22 is E2, the ratio of the Young's modulus E1 to the Young's modulus E2 is designed to satisfy E2 / E1≧10. By using the first member 18 and the second member 22 satisfying this relationship, the vibration of the glass plate structure 12 generated by the vibration of the vibrator 14 can be attenuated by the first member 18, and the vibration can be suppressed from propagating to the second member 22. In addition, the ratio of the Young's modulus E1 to the Young's modulus E2 is preferably E2 / E1≧20, more preferably E2 / E1≧30, and even more preferably E2 / E1≧50.

[0040] In particular, for the glass vibration plate module 10 satisfying the above ratio (E2 / E1), when the glass vibration plate 11 is used for a vehicle window glass, the vibration of the vibrator 14 can be effectively suppressed from propagating to the entire outer panel of the vehicle. In addition, as the resin layer 20 for fixing the glass plate structure 12 and the first component 18 (adhesion), even when using the resin layer 20 with a Young's modulus E2 / E1, the glass plate structure 12 and the first component 18 can be effectively suppressed from propagating to the entire outer panel of the vehicle. R 1×10 7 In the case of a high-rigidity adhesive of greater than Pa, the first component 18 can also be used to attenuate vibration, so that the glass plate structure 12 can be firmly fixed to the first component 18 and the propagation of vibration can be suppressed, thereby suppressing the generation of components different from the sound generated by vibrating the glass plate structure 12, that is, noise.

[0041] Furthermore, when the first member 18 is a tailgate made of resin, it is possible to achieve a lighter weight than a tailgate made of metal, and thus improve the fuel efficiency of the vehicle.

[0042] <Second embodiment>

[0043] Reference Figure 3 A glass diaphragm module 30 according to a second embodiment will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be appropriately omitted.

[0044] Figure 3 FIG. 2 is a schematic diagram of the glass diaphragm module 30 according to the second embodiment, as viewed from the side of the vehicle. Figure 3 As shown, the glass diaphragm module 30 of the present embodiment includes a glass diaphragm 11 , and the glass diaphragm 11 includes a glass plate structure 12 and a vibrator 14 .

[0045] Figure 3This is an example in which the glass sheet structure 12 is used for a side window glass slidably arranged on the side of a vehicle. The glass sheet structure 12 has the same structure as that of the first embodiment and is formed in the shape of a side window glass.

[0046] A vibrator 14 is mounted at the lower end of the glass plate structure 12. Even in the fully closed state where the glass plate structure 12 is located at the uppermost side, the vibrator 14 is located inside the door panel and cannot be visually recognized by the occupant. In addition, when the slidable side window glass is fully closed in the vehicle, the side corresponding to the portion overlapping the lower side of the opening is called the waistline, and the vibrator 14 can be arranged in any area as long as it is located in an area below the waistline.

[0047] exist Figure 3 In the figure, a pair of retaining frames 36 are installed along the front and rear sides of the lower end of the glass plate structure 12. The retaining frames 36 are formed into a roughly U-shape when viewed from the front-rear direction of the vehicle (the end surface direction of the glass plate structure 12), clamping the lower end of the glass plate structure 12 and supporting the glass plate structure 12 from below. The pair of retaining frames 36 are connected to a slider 38, and the slider 38 is configured to be able to move up and down along a guide rail not shown. Therefore, the glass plate structure 12 slides up and down by the up and down movement of the slider 38. In addition, in Figure 3 In FIG. 1 , an example is shown in which two retaining frames 36 are provided, but the number may be one, or three or more.

[0048] A first member 32 made of resin is attached to the peripheral end of the glass diaphragm 11 via a resin layer (not shown). The first member 32 is continuously provided in a region of more than half of the peripheral end of the glass diaphragm 11. Figure 3 In the embodiment, the first member 32 is disposed in the region excluding the lower edge of the glass diaphragm 11. Alternatively, as the first member 32, a weather strip for sealing between the side window glass and the vehicle body may be used.

[0049] A second metal member 34 is disposed separately from the glass vibration plate 11. The second member 34 is connected to the first member. Figure 3 In the embodiment, the door frame is used as the second member 34. Here, in the fully closed state of the glass diaphragm 11, the first member 32 and the second member 34 are in close contact with each other.

[0050] The Young's modulus E1 of the first member 32 and the Young's modulus E1 of the second member 34 only need to satisfy E2 / E1≧10, and the range described in the first embodiment can be applied as a preferred range.

[0051] <Third Embodiment>

[0052] Reference Figure 4A glass diaphragm module 40 according to a third embodiment will be described. Note that the same reference numerals are given to the same configurations as those in the first embodiment, and description thereof will be appropriately omitted.

[0053] Figure 4 is a cross-sectional view of the glass vibration plate module 40 according to the third embodiment as viewed from the side. Figure 4 As shown, the glass diaphragm module 40 of the present embodiment includes a glass diaphragm 11 , and the glass diaphragm 11 includes a glass plate structure 12 and a vibrator 14 .

[0054] Figure 4 The glass plate structure 12 shown has the same structure as the first embodiment and is formed of a single plate glass into a substantially rectangular plate shape, but may also be a laminated glass. In addition, a vibrator 14 is attached to one main surface of the glass plate structure 12 via an attachment portion 16 .

[0055] The first member 42 is attached to one main surface of the glass sheet structure 12 via the resin layer 20. The resin layer 20 has the same structure as that of the first embodiment, and is provided over the entire circumference of the peripheral end portion of the glass sheet structure 12.

[0056] The first member 42 includes a bottom portion 42A facing the main surface of the glass plate structure 12 and a peripheral wall portion 42B protruding from the peripheral end portion of the bottom portion 42A toward the glass plate structure 12, and the peripheral wall portion 42B is bonded to the glass diaphragm 11 via the resin layer 20. The first member 42 can be made of the same material as that of the first embodiment.

[0057] The second member 44 is disposed apart from the glass diaphragm 11 and connected to the first member 42. The second member 44 is a substantially rectangular plate-shaped member fixed to the bottom 42A of the first member 42, and the same material as that of the first embodiment can be used.

[0058] The Young's modulus E1 of the first member 42 and the Young's modulus E2 of the second member 44 only need to satisfy E2 / E1≧10, and the range described in the first embodiment can be applied as a preferred range.

[0059] Even in a structure where the second member 44 is not a frame as in this embodiment, the sound generated by the glass plate structure 12 vibrating due to the vibration of the vibrator 14 can be effectively prevented from propagating to the outside (via the frame). The glass diaphragm module 40 of this embodiment can be used in electronic devices and the like.

[0060] <Fourth embodiment>

[0061] Reference Figure 5A glass diaphragm module 50 according to a fourth embodiment will be described. Note that the same reference numerals are given to the same configurations as those in the first embodiment, and description thereof will be appropriately omitted.

[0062] Figure 5 FIG. 4 is a schematic diagram showing an example in which the glass diaphragm module 50 according to the fourth embodiment is applied to a window glass for a building, and is viewed from the indoor side. Figure 5 As shown, the glass diaphragm module 50 of the present embodiment includes a pair of left and right glass diaphragms 11 , and each glass diaphragm 11 includes a glass plate structure 12 and a vibrator 14 .

[0063] Figure 5 The glass plate structure 12 shown is the same structure as the first embodiment, and is formed into a substantially rectangular plate shape by a single plate glass, but may also be a laminated glass. Figure 5 In the embodiment, the glass plate structure 12 is a structure that divides the interior and exterior of the building, and allows the exterior to be visually confirmed from the interior of the building through the glass plate structure 12. In addition, although the glass plate structure 12 is used for a non-openable (fixed) window glass, it can also be used for an openable window glass.

[0064] The vibrator 14 is attached to the glass plate structure 12. The vibrator 14 is attached to the center of the glass plate structure 12, but may be attached to the peripheral end of the glass plate structure 12. The portion where the vibrator 14 is attached may be covered with a member such as an interior material.

[0065] The first member 52 is attached to the peripheral end of the glass diaphragm 11 via a resin layer (not shown). The first member 52 is a first frame body surrounding the glass diaphragm 11, and the same resin as that of the first embodiment can be used.

[0066] A second member 54 as a second frame body is disposed outside the first member 52. The second member 54 is disposed so as to be separated from the glass vibration plate 11 and connected to the first member 52. Figure 5 In the embodiment, the second component 54 is formed in a shape surrounding the two first components 52 and is formed of a metal supporting the glass vibration plate 11. In addition, the second component 54 can use the same metal as the first embodiment. Here, the Young's modulus E1 of the first component 52 and the Young's modulus E2 of the second component 54 only need to satisfy E2 / E1≧10, and as a preferred range, the range described in the first embodiment can be applied.

[0067] By applying the glass diaphragm 11 to a building window glass as in the present embodiment, it is possible to suppress the propagation of sound generated by the glass plate structure 12 vibrating due to the vibration of the vibrator 14 to the wall of the building (via the frame).

[0068] <Example>

[0069] Hereinafter, the embodiments of the present disclosure are described in more detail by enumerating examples. The materials, sizes, shapes and evaluation procedures shown in the following examples can be appropriately changed as long as they do not depart from the gist of the embodiments of the present disclosure. Therefore, the scope of the embodiments of the present disclosure is not limited to the specific examples shown below.

[0070] (Glass plate structure)

[0071] Figure 6 1 is a front view showing a glass diaphragm module 110 of the embodiment in the middle of being assembled. Figure 6 As shown, the glass plate structure 100 is a single plate glass, and is formed into a substantially rectangular plate shape. The length L of the glass plate structure 100 in the longitudinal direction is G The width direction is 300mm. G The thickness of the glass sheet structure 100 is 3.2 mm.

[0072] (First component)

[0073] The first component 102 is a first frame body formed of a PVC resin, and has an opening 102A formed in the center. The length L1 of the first component 102 in the longitudinal direction is 520 mm, and the length H1 in the width direction is 420 mm. In addition, the thickness of the first component 102 is 3.0 mm. The length L1 of the opening 102A in the longitudinal direction is 520 mm, and the length H1 in the width direction is 420 mm. H The width direction is 220 mm. H It is 120mm.

[0074] (Resin layer)

[0075] Figure 7 1 is a front view showing a glass vibration plate module 110 of the embodiment. Figure 8 It will be used Figure 7 The sectional view is a partially cutaway view of the state after the 8-8 line is cut. Figure 8 As shown, the first component 102 is attached to the peripheral end of the glass plate structure 100 via a resin layer 103. The resin layer 103 uses an adhesive (SikaTack (registered trademark) GO!, manufactured by SIKA Corporation) for bonding the glass plate structure 100 and the first component 102. The width of the resin layer 103 is 2.4 mm and the thickness is 6.4 mm.

[0076] (Second component)

[0077] like Figure 7 and Figure 8As shown, the second member 104 is a second frame body formed of aluminum, and the length L2 of the second member 104 in the longitudinal direction is 550 mm, and the length H2 in the width direction is 450 mm. In addition, the thickness of the second member 104 is 3.0 mm.

[0078] (Connection)

[0079] The first member 102 and the second member 104 are mechanically fastened by a plurality of screws 105 as a connection portion. The screws 105 are arranged at 10 locations around the first member 102 at intervals.

[0080] (Vibrator)

[0081] like Figure 7 As shown, the vibrator 106 is attached to the center of the glass plate structure 100 using an adhesive tape (9473PC, manufactured by 3M). The vibrator 106 vibrates in the thickness direction of the glass plate structure 100 and is configured to vibrate at a period corresponding to an input signal.

[0082] An acceleration sensor 108 (NP-3200, manufactured by Ono Instruments) is attached to the peripheral end of the second member 104. The analysis of the measurement data measured by the acceleration sensor 108 is performed by a real-time acoustic vibration analysis system (DS-3200, manufactured by Ono Instruments).

[0083] (Measurement method)

[0084] Sine waves of 40 Hz, 60 Hz, 80 Hz, and 100 Hz are applied to the vibrator 106 at 1 V, and the magnitude of acceleration at each frequency is measured by the acceleration sensor 108. In addition, the material of the first component 102 can be replaced with aluminum for the same measurement. In addition, when the first component 102 is PVC, E2 / E1=20, and the Young's modulus E1 of the first component 102 and the Young's modulus E2 of the second component 104 satisfy E2 / E1≧10, but when the first component 102 is aluminum, E2 / E1=1, which does not satisfy the above condition.

[0085] (Measurement results)

[0086] The measurement results are shown in Table 1 below.

[0087] [Table 1]

[0088] Material of the first component 40Hz 60Hz 80Hz 100Hz PVC 0.47 0.48 0.29 0.12 aluminum 1.82 1.57 0.99 0.48

[0089] According to the results described in Table 1, the measured value of the acceleration sensor is reduced by using PVC as the first component 102. That is, the vibration of the vibrator 106 is greatly attenuated by the first component 102. In particular, in the low-frequency region with a large amplitude value, the attenuation effect of the vibration of the second component becomes significant, and the amount of noise generated can be greatly suppressed.

[0090] According to the above results, for example, for a glass vibration plate fixed to a car door formed of a resin material, vibration is not easily transmitted to the metal frame that becomes the shell, which is very effective in applications that excite glass. Similarly, it can be widely used in products that excite glass in building window glass and electronic equipment. In addition, as long as the Young's modulus E1 of the first component and the Young's modulus E2 of the second component satisfy E2 / E1≧10, the first component can be formed of a material other than resin, and the second component can be formed of a material other than metal.

[0091] As mentioned above, although the glass diaphragm modules 10 , 30 , 40 , and 50 according to the embodiments have been described, it is needless to say that the glass diaphragm modules 10 , 30 , 40 , and 50 can be implemented in various forms without departing from the gist of the present disclosure.

[0092] The entire disclosure of Japanese Patent Application No. 2022-158995 is incorporated into this specification by reference.

[0093] All documents, patent applications, and technical standards described in this specification are incorporated herein by reference as if each document, patent application, and technical standard was specifically and individually described as being incorporated by reference.
