Description

Glass diaphragm module

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

[0002] In recent years, technologies have been developed to vibrate glass sheets to function as speakers. International Publication No. 2022 / 009180 discloses a structure in which a transducer is encapsulated in laminated glass having an outer glass layer, an inner glass layer, and an intermediate layer, causing the laminated glass to function as a speaker. U.S. Patent Application Publication No. 2015 / 0298656 discloses a structure in which a plurality of exciters are attached to a vehicle windshield to cause the windshield to function as a speaker. Japanese Patent Application Laid-Open No. 2021-180486 discloses a structure in which an acoustic generator is disposed in a vehicle window glass, and the vehicle window glass is vibrated to output sound.

[0003] However, in structures such as those described in Patent Documents 1 to 3, which achieve speaker functionality by vibrating a glass plate, the vibrations of the glass plate are transmitted to components that fix the periphery of the glass plate, which can result in the generation of unpredictable sounds, i.e., noise, that are different from the sounds that are originally intended to be generated by the glass plate, making it difficult to generate the original high-quality sound.

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

[0005] The glass diaphragm module according to the present disclosure includes a glass diaphragm including a glass plate structure and a vibrator attached to the glass plate structure, a first member attached to a peripheral edge of the glass diaphragm via a resin layer, and a second member disposed apart from the glass diaphragm and connected to the first member, wherein the Young's modulus E1 of the first member and the Young's modulus E2 of the second member are such that E ２ / E １ ≧10.

[0006] The glass diaphragm module according to the present disclosure can suppress the generation of noise, which is a component different from the sound generated by vibrating the glass plate structure.

[0008] First Embodiment A glass diaphragm module 10 according to a first embodiment will be described with reference to the drawings.

[0009] 1 is a schematic view of a glass vibration plate module 10 seen from the rear side of a vehicle. As shown in FIG. 1, the glass vibration plate module 10 of this embodiment includes a glass vibration plate 11, which includes a glass plate structure 12 and a vibrator 14.

[0010] The glass plate structure 12 can be used for window glass for vehicles such as windshields, side glass, rear glass, rear quarter glass, front bench glass, and roof glass, but can also be used for applications other than vehicles, such as window glass for railways, aircraft, and buildings.

[0011] Fig. 1 shows an example in which a glass plate structure 12 is used as a rear glass disposed at the rear of a vehicle. In Fig. 1, the X-axis indicates the vehicle width direction when the glass plate structure 12 is assembled to the vehicle, with the right side of the vehicle coinciding with the positive direction of the X-axis. Furthermore, the Y-axis indicates the vertical direction when the glass plate structure 12 is assembled to the vehicle, with the upper side of the vehicle coinciding with the positive direction of the Y-axis.

[0012] Fig. 2 is a cross-sectional view taken along line 2-2 in Fig. 1, and the Z axis in Fig. 2 indicates the longitudinal direction of the vehicle when the glass plate structure 12 is assembled to the vehicle. As shown in Fig. 2, the glass plate structure 12 is made of single glass, but it may also be made of laminated glass. The glass plate structure 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] The glass plate structure 12 may be formed of organic glass, such as a PMMA (polymethyl methacrylate)-based resin, a PC (polycarbonate)-based resin, a PS (polystyrene)-based resin, a PET (polyethylene terephthalate)-based resin, a PVC (polyvinyl chloride)-based resin, or a cellulose-based resin.

[0014] The thickness of the glass plate construct 12 is preferably 1.0 mm or more, more preferably 2.0 mm or more, and even more preferably 3.0 mm or more. This allows the glass plate construct 12 to have a necessary and sufficient strength. The thickness of the glass plate construct 12 is preferably 7.0 mm or less, more preferably 6.0 mm or less, and even more preferably 5.0 mm or less.

[0015] Furthermore, when the glass plate construct 12 is constructed of laminated glass in which an intermediate layer is sandwiched between a pair of glass plates, the thickness of each of the pair of glass plates constituting the glass plate construct 12 is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1.0 mm or more. The thicknesses of the pair of glass plates constituting the glass plate construct 12 may be the same or different.

[0016] When the glass plate structure 12 is used as a laminated glass, the intermediate layer can be, for example, a transparent polyvinyl butyral (PVB)-based or ethylene-vinyl acetate copolymer (EVA)-based resin film, or a resin film containing a thermosetting adhesive material such as a silicone (PDMS)-based, polyurethane-based, fluorine-based, polyethylene terephthalate-based, or polycarbonate-based material. The intermediate layer may also contain a material that enhances sound insulation, or a material that absorbs ultraviolet or infrared rays. The thickness of the intermediate layer 18 may 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.

[0017] 2, the glass plate structure 12 is flat, but it may have a curved shape. For example, the glass plate structure 12 may be curved so as to bulge toward the rear of the vehicle when viewed from the side of the vehicle.

[0018] A light-shielding layer 13 having a predetermined width and formed of a black ceramic layer or the like is provided on the outer periphery of the glass diaphragm 11, and a vibrator 14 is arranged so as to overlap the light-shielding layer 13. The vibrator 14 is attached to the glass plate construct 12 via a mount 16 made of metal or resin. For example, a fixing portion such as a screw may be provided on one of the mount 16 and the vibrator 14, and a screw hole or the like may be provided on the other of the mount 16 and the vibrator 14, so that the vibrator 14 and the mount 16 are mechanically fastened together. Attaching the vibrator 14 to the glass plate construct 12 via the mount 16 makes it easy to remove and replace the vibrator 14, but the vibrator 14 may also be directly fixed (by adhesive) to the glass plate construct 12 without providing the mount 16.

[0019] 2 shows an example in which the vibrator 14 is attached to the upper end of the glass plate construct 12, but the vibrator 14 may be attached to other locations. For example, the vibrator 14 may be attached to the lower end of the glass plate construct 12. Furthermore, a plurality of vibrators 14 may be attached to the glass plate construct 12.

[0020] The vibrator 14 is connected to a power source (not shown) and vibrates the glass plate construct 12 in response to an input electrical signal. In one example, the vibrator 14 of this embodiment is a voice coil motor including a coil portion and a magnetic circuit, with one of the coil portion and the magnetic circuit fixed to the glass plate construct 12 and the other disposed so as to be movable relative to the glass plate construct 12. When a current flows through the coil portion, the interaction between the coil portion and the magnetic circuit generates vibrations, causing the glass plate construct 12 to vibrate via the mount portion 16. The vibration direction is the thickness direction of the vibrator 14. The vibrator 14 is not limited to a voice coil motor; any actuator other than a voice coil motor, such as a piezoelectric actuator, can be used as long as it is capable of transmitting the desired vibrations to the glass plate construct 12.

[0021] The first member 18 is attached to the peripheral edge of the glass plate construct 12 via a resin layer 20. The resin layer 20 may be provided continuously over at least half the total length (total perimeter) of the peripheral edge of the glass plate construct 12. The length of the continuous layer is preferably at least 6 / 10 of the total perimeter of the glass plate construct 12, more preferably at least 7 / 10, even more preferably at least 8 / 10, and most preferably at least 9 / 10 of the total perimeter (total perimeter). The resin layer 20 of this embodiment is provided over the entire perimeter of the peripheral edge of the glass plate construct 12. For example, even when the glass plate construct 12 is used for a movable window glass such as a side glass or roof glass, a configuration in which the glass plate construct 12 is in contact with a resin layer of rubber or foam material over the entire perimeter when fully closed may be adopted.

[0022] The resin layer 20 is an adhesive layer that bonds the glass plate structure 12 and the first member 18. The Young's modulus E Ｒ is 1 x 10 ６ [Pa] ~ 1 x 10 ８ [Pa] is preferred, and 1 × 10 ７ [Pa] ~ 1 x 10 ８ [Pa] is more preferable, and 5 × 10 ７ [Pa] ~ 1 x 10 ８ [Pa] is more preferred.

[0023] The resin layer 20 can be configured to contain at least one resin selected from the group consisting of urethane-based, phenol-based, butyl-based, synthetic rubber-based, acrylic-based, epoxy-based, silicone-based, epoxysilicone-based, and polyvinyl chloride-based resins. Furthermore, the first member 18, the second member 22, and the glass plate structure 12 may be configured to have a primer pre-applied thereon. For example, a primer containing at least one component such as polyol, polyisocyanate, a silane coupling agent, carbon black, and silica particles can be used as the body primer and the glass primer.

[0024] The first member 18 is a first frame that surrounds the glass vibration plate 11, and an example of the first member 18 is a plastic back door. The first member 18 has a recess 18A that is recessed toward the front of the vehicle, and the glass vibration plate 11 is disposed in the recess 18A. The recess 18A has an opening 18B that is closed by the glass vibration plate 11.

[0025] The first member 18 may be made of a general engineering plastic such as an ABS-based, PVC-based, PC-based, PP-based, PBT-based, PA66-based, or PPS-based plastic, or may be made of a fiber-reinforced plastic containing glass fiber or carbon fiber. Furthermore, a metal reinforcement may be provided to reinforce the first member 18. In the case of a resin back door that uses a reinforcement to reinforce the first member 18, the glass diaphragm module 10 may include a resin member (resin panel) (not shown) that faces the first member 18 and is fixed so as to sandwich the reinforcement. Furthermore, the Young's modulus E of the first member 18 may be set to 0.05 mm. １ is 1 x 10 ８ [Pa] ~ 1 x 10 １1 [Pa] is preferred, and 2 × 10 ８ [Pa] ~ 5 x 10 １０ [Pa] is more preferable, and 5 × 10 ８ [Pa] ~ 1 x 10 １０ [Pa] is more preferred.

[0026] 1 and 2, a second member 22, which is a second frame, is disposed outside the first member 18. The second member 22 is disposed away from the glass vibration plate 11 and is connected to the first member 18. In FIG. 2, the lower end of the first member 18 is overlapped with the surface of the second member 22 facing the rear of the vehicle. Similarly, both left and right edges of the first member 18 are overlapped with the second member 22 (see FIG. 1).

[0027] 2 , 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 together, and for example, a hinge that connects the first member 18 to the second member 22 in a swingable manner can be used as the connecting portion 24.

[0028] The first member 18 and the second member 22 may be bonded together with an adhesive, or a fastening member such as a bolt may be combined with the adhesive.

[0029] The second member 22 is made of a material containing metal and may be a metal vehicle exterior panel, etc. If the first member 18 is a resin tailgate, the second member 22 may be a vehicle exterior panel that supports the tailgate. Examples of metals that can be used to make the second member 22 include aluminum, iron, and stainless steel.

[0030] Young's modulus E of the second member 22 ２ is 1 x 10 １０ [Pa] ~ 1 x 10 １２ [Pa] is preferred, and 2 × 10 １０ [Pa] ~ 5 x 10 １１ [Pa] is more preferable, and 5 × 10 １０ [Pa] ~ 1 x 10 １１ [Pa] is more preferred.

[0031] Here, the Young's modulus of the first member 18 is E １ and the Young's modulus of the second member 22 is E ２ In this case, Young's modulus E １ and Young's modulus E ２ The ratio of ２ / E １≧10. By using the first member 18 and the second member 22 that satisfy this relational expression, 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 propagation of the vibration to the second member 22 can be suppressed. １ and Young's modulus E ２ The ratio of ２ / E １ ≧20 is preferred, E ２ / E １ More preferably, E ２ / E １ ≧50 is even more preferred.

[0032] In particular, the above ratio (E ２ / E １ ) is used in a vehicle window glass, the glass vibration plate module 10 can effectively suppress the vibration of the vibrator 14 from propagating to the entire outer panel of the vehicle. Ｒ is 1 x 10 ７ Even when a high-rigidity adhesive of tensile strength [Pa] or more is used, vibration can be damped by the first member 18, so that the glass plate construct 12 can be firmly fixed to the first member 18 while suppressing the propagation of vibration and suppressing the generation of noise, which is a component different from the sound generated by vibrating the glass plate construct 12.

[0033] Furthermore, if the first member 18 is a resin back door, it can be made lighter than a metal back door, and the fuel efficiency of the vehicle can be improved.

[0034] Second Embodiment A glass diaphragm module 30 according to a second embodiment will be described with reference to Fig. 3. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0035] 3 is a schematic view of a glass vibration plate module 30 according to a second embodiment, seen from the side of a vehicle. As shown in FIG. 3, the glass vibration plate module 30 of this embodiment includes a glass vibration plate 11, which includes a glass plate structure 12 and a vibrator 14.

[0036] 3 shows an example in which the glass plate structure 12 is used for a side glass that is slidably disposed on the side of a vehicle. The glass plate structure 12 has the same structure as that of the first embodiment and is formed in the shape of the side glass.

[0037] A vibrator 14 is attached to the lower end of the glass plate structure 12. The vibrator 14 is located inside the door panel even when the glass plate structure 12 is in the uppermost position and in a fully closed state, and is therefore not visible to the occupants. When the slidable side glass is fully closed in the vehicle, the side that overlaps with the lower side of the opening is called the belt line, and the vibrator 14 can be placed in any area below this belt line.

[0038] In Fig. 3, a pair of holders 36 are attached to the front and rear of the lower end of the glass plate construct 12. The holders 36 are formed in a substantially U-shape when viewed from the vehicle longitudinal direction (the end face direction of the glass plate construct 12), and clamp the lower end of the glass plate construct 12, supporting the glass plate construct 12 from below. The pair of holders 36 are connected to sliders 38, which are configured to be movable up and down along guide rails (not shown). Therefore, the glass plate construct 12 slides up and down as the sliders 38 move up and down. Note that Fig. 3 shows an example in which two holders 36 are provided, but the number may be one or three or more.

[0039] A resin first member 32 is attached to the peripheral edge of the glass vibration plate 11 via a resin layer (not shown). The first member 32 is provided continuously over more than half of the peripheral edge of the glass vibration plate 11, and in Fig. 3, the first member 32 is disposed over the area excluding the lower edge of the glass vibration plate 11. Note that a weather strip that seals between the side glass and the vehicle body may also be used as the first member 32.

[0040] A metal second member 34 is disposed away from the glass vibration plate 11. The second member 34 is connected to the first member, and in Fig. 3, a door frame is used as the second member 34. Here, when the glass vibration plate 11 is in the fully closed state, the first member 32 is in close contact with the second member 34.

[0041] Young's modulus E of the first member 32 １ and the Young's modulus E of the second member 34 １ That is, E ２ / E １ It is sufficient that the condition ≧10 is satisfied, and the range described in the first embodiment can be applied as a preferable range.

[0042] Third Embodiment A glass diaphragm module 40 according to a third embodiment will be described with reference to Fig. 4. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

[0043] 4 is a cross-sectional side view of a glass diaphragm module 40 according to a third embodiment. As shown in FIG. 4, the glass diaphragm module 40 of this embodiment includes a glass diaphragm 11, which includes a glass plate structure 12 and a vibrator 14.

[0044] The glass plate structure 12 shown in Fig. 4 has the same structure as that of the first embodiment, and is formed of a single glass plate in a substantially rectangular plate shape, but may be made of laminated glass. A vibrator 14 is attached to one main surface of the glass plate structure 12 via a mount portion 16.

[0045] A first member 42 is attached to one main surface of the glass plate construct 12 via a resin layer 20. The resin layer 20 has the same configuration as in the first embodiment, and is provided around the entire periphery of the peripheral end portion of the glass plate construct 12.

[0046] The first member 42 includes a bottom portion 42A facing the main surface of the glass plate construct 12 and a peripheral wall portion 42B protruding from the peripheral end of the bottom portion 42A toward the glass plate construct 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 in the first embodiment.

[0047] The second member 44 is disposed away from the glass diaphragm 11 and is connected to the first member 42. The second member 44 is a substantially rectangular plate-shaped member fixed to the bottom portion 42A of the first member 42, and can be made of the same material as in the first embodiment.

[0048] Young's modulus E of the first member 42 １ and the Young's modulus E of the second member 44 ２ That is, E ２ / E １ It is sufficient that the condition ≧10 is satisfied, and the range described in the first embodiment can be applied as a preferable range.

[0049] Even in a structure in which the second member 44 is not a frame, as in the present embodiment, it is possible to effectively suppress propagation to the outside (via the frame) of sound generated by the vibration of the vibrator 14 causing the glass plate structure 12 to vibrate. The glass diaphragm module 40 of the present embodiment can be used in electronic devices, etc.

[0050] Fourth Embodiment A glass diaphragm module 50 according to a fourth embodiment will be described with reference to Fig. 5. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted where appropriate.

[0051] 5 is a schematic view of an example in which a glass diaphragm module 50 according to the fourth embodiment is applied to architectural window glass in a building, as seen from the inside of the room. As shown in FIG. 5, the glass diaphragm module 50 of this embodiment includes a pair of left and right glass diaphragms 11, each of which includes a glass plate structure 12 and a vibrator 14.

[0052] The glass plate structure 12 shown in Fig. 5 has the same structure as that of the first embodiment, and is formed of a single glass sheet into a substantially rectangular plate shape, but may be laminated glass. Also, in Fig. 5, the glass plate structure 12 separates the interior and exterior of a building, and the exterior can be seen from inside the building through the glass plate structure 12. Also, although the glass plate structure 12 is used in a non-openable (fixed) window glass, it may also be used in an openable window glass.

[0053] A vibrator 14 is attached to the glass plate construct 12. The vibrator 14 is attached to the center of the glass plate construct 12, but may also be attached to the peripheral edge of the glass plate construct 12. The portion where the vibrator 14 is attached may be covered with an interior material or the like.

[0054] A first member 52 is attached to the peripheral edge of the glass diaphragm 11 via a resin layer (not shown). The first member 52 is a first frame that surrounds the glass diaphragm 11, and the same resin as in the first embodiment can be used for the first member 52.

[0055] A second member 54, which is a second frame, is disposed outside the first member 52. The second member 54 is disposed away from the glass diaphragm 11 and connected to the first member 52. In FIG. 5, the second member 54 is formed in a shape that surrounds the two first members 52 and is made of a metal that supports the glass diaphragm 11. The second member 54 can be made of the same metal as in the first embodiment. Here, the Young's modulus E of the first member 52 is １ and the Young's modulus E of the second member 54 ２ That is, E ２ / E １ It is sufficient that the condition ≧10 is satisfied, and the range described in the first embodiment can be applied as a preferable range.

[0056] As in this embodiment, by applying the glass vibration plate 11 to architectural window glass, it is possible to prevent the sound generated by the vibration of the vibrator 14 causing the glass plate structure 12 to vibrate from propagating to the wall of the building (via the frame).

[0057] <Examples> The following examples further illustrate the embodiments of the present disclosure. The materials, dimensions, shapes, and evaluation procedures shown in the following examples can be changed as appropriate without departing from the spirit 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.

[0058] (Glass Plate Structure) Fig. 6 is a front view showing a state in the middle of assembling the glass vibration plate module 110 of the embodiment. As shown in Fig. 6, the glass plate structure 100 is a single glass plate formed in a substantially rectangular plate shape. The longitudinal length L of the glass plate structure 100 is Ｇ is 300 [mm], and the length in the short direction H Ｇ The length is 200 mm. The thickness of the glass plate structure 100 is 3.2 mm.

[0059] (First Member) The first member 102 is a first frame body made of PVC resin, and has an opening 102A formed in the center. The length L of the first member 102 in the longitudinal direction １ is 520 mm, and the length in the short direction H １ The length L of the opening 102A in the longitudinal direction is 420 mm. The thickness of the first member 102 is 3.0 mm. Ｈ is 220 mm, and the length H Ｈ is 120 [mm].

[0060] (Resin Layer) Fig. 7 is a front view showing the glass diaphragm module 110 of the embodiment, and Fig. 8 is a cross-sectional view showing a state cut along line 8-8 in Fig. 7, with a part broken away. As shown in Fig. 8, the first member 102 is attached to the peripheral edge of the glass plate structure 100 via a resin layer 103. The resin layer 103 uses an adhesive (Sika Tack (registered trademark) GO!, manufactured by Sika Corporation) that bonds the glass plate structure 100 and the first member 102. The resin layer 103 has a width of 2.4 mm and a thickness of 6.4 mm.

[0061] (Second Member) As shown in FIGS. 7 and 8, the second member 104 is a second frame body made of aluminum. ２ is 550 [mm], and the length in the short direction H ２ The length of the second member 104 is 450 mm. The thickness of the second member 104 is 3.0 mm.

[0062] (Connection Portion) The first member 102 and the second member 104 were mechanically fastened together by a plurality of screws 105, which were the connection portion. The screws 105 were arranged at ten locations around the periphery of the first member 102 at intervals.

[0063] 7, a vibrator 106 was attached with adhesive tape (9473PC, manufactured by 3M) to the center of the glass plate structure 100. The vibration direction of the vibrator 106 was the thickness direction of the glass plate structure 100, and the vibrator 106 was configured to be able to vibrate at a period corresponding to an input signal.

[0064] An acceleration sensor 108 (NP-3200, manufactured by Ono Sokki Co., Ltd.) was attached to the peripheral end of the second member 104. The measurement data measured by the acceleration sensor 108 was analyzed using a real-time acoustic vibration analysis system (DS-3200, manufactured by Ono Sokki Co., Ltd.).

[0065] (Measurement Method) Sine waves of 40 [Hz], 60 [Hz], 80 [Hz], and 100 [Hz] at 1 [V] were applied to the vibrator 106, and the magnitude of acceleration at each frequency was measured by the acceleration sensor 108. In addition, the material of the first member 102 was changed to aluminum, and the same measurement was performed. Note that when the first member 102 is PVC, E ２ / E １ = 20, and the Young's modulus E １ and the Young's modulus E of the second member 104 ２ But, E ２ / E １ ≧10, but the first member 102 is made of aluminum, ２ / E １ = 1, and the above condition is not met.

[0066] (Measurement Results) The measurement results are shown in Table 1 below.

[0067]

[0068] The results shown in Table 1 show that the acceleration sensor measurement value was reduced by using PVC as the first member 102. In other words, the vibration of the vibrator 106 was significantly attenuated by the first member 102. In particular, in the low frequency range where the amplitude value is large, the effect of attenuating the vibration to the second member was significant, making it possible to significantly reduce the amount of noise generated.

[0069] From the above results, for example, a glass vibration plate fixed to an automobile door made of a resin material is very effective in applications where vibration is hardly transmitted to the metal frame that serves as the housing. Similarly, it can be widely applied to products that vibrate glass, such as architectural window glass and electronic equipment. Furthermore, if the Young's modulus E1 of the first member and the Young's modulus E2 of the second member are equal to or greater than E, ２ / E １As long as the condition of ≧10 is satisfied, the first member may be formed of a material other than resin, and the second member may be formed of a material other than metal.

[0070] The glass diaphragm modules 10, 30, 40, and 50 according to the embodiments have been described above, but it goes without saying that they can be implemented in various forms without departing from the spirit and scope of the present disclosure. The disclosure of Japanese Patent Application No. 2022-158995 is incorporated herein by reference in its entirety. All documents, patent applications, and technical standards described herein are incorporated by reference into this specification to the same extent as if each individual document, patent application, and technical standard were specifically and individually indicated to be incorporated by reference.
