Abstract
Description
Glass diaphragm module
[0001] This disclosure relates to a glass diaphragm module.
[0002] In recent years, technologies that enable a glass plate to function as a speaker by vibrating it have been under consideration. In International Publication No. 2019 / 172076, there is disclosed a speaker device including a diaphragm having light permeability, an exciter (vibrator) that generates vibrations according to an input electric signal, and a vibration transmission unit that is connected to the diaphragm and the exciter and transmits vibrations from the exciter to the diaphragm.
[0003] In such a speaker device, in order to connect an exciter that generates vibrations to another device, a wiring provided with a connector at its tip is connected to the exciter. The exciter generates vibrations. Therefore, the vibrations generated by the exciter are transmitted to the connector via the wiring, and there is a possibility that the connector may be damaged due to the vibrations.
[0004] In consideration of the above facts, an object of this disclosure is to obtain a glass diaphragm module capable of suppressing damage to the connector.
[0005] The glass diaphragm module according to this disclosure includes a glass diaphragm that forms a window glass in an opening of a vehicle, a vibration component that is attached to the glass diaphragm and vibrates the glass diaphragm, a wiring having one end connected to the vibration component, a connector to which the other end of the wiring is connected, and a fixing portion that fixes the connector to a vehicle component near the opening.
[0006] As described above, the glass diaphragm module according to this disclosure has an excellent effect of being able to suppress damage to the connector.

This is a diagram showing a fixing part according to a modified example of each embodiment.
[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 Embodiment] First, the glass diaphragm module 10 according to the first embodiment will be described with reference to Figures 1 to 4.
[0010] In this embodiment, for example, the glass diaphragm module 10 is applied to the roof glass 20 of a vehicle. As shown in Figure 1, the glass diaphragm module 10 comprises a roof glass (glass plate) 20 fixed to an opening in the vehicle, a vibrator (vibrating component) 30 that vibrates the roof glass 20 to function as a speaker, a vibrator-side harness (wiring) 40 with one end connected to the vibrator 30, a vibrator-side connector 50 to which the other end of the vibrator-side harness 40 is connected, a fixing part 60 that fixes the connector 50 to a vehicle component 11 near the opening, and a power supply-side harness 70 that connects the fixing part 60 to a power supply (not shown). Here, "near the opening" refers to the area within 50 cm from the outer edge of the opening. Vehicle component refers to the components that make up the vehicle, excluding the glass diaphragm module 10, and specifically refers to the vehicle body, interior materials, etc.
[0011] (Roof glass) The roof glass 20 constitutes the vehicle's window glass. The roof glass 20 separates the interior space S1 from the exterior space S2. The roof glass 20 is fixed to the vehicle component 11 in a manner that prevents sliding movement. The end of the roof glass 20 is fixed to the vehicle component 11 via a fixing member 12. The fixing member 12 is attached to the lower surface of the end of the roof glass 20.
[0012] The roof glass 20 may be single-pane glass or laminated glass in which two glass plates are bonded together with a resin intermediate layer. The roof glass 20 is made of transparent or translucent inorganic glass. Examples of inorganic glass that can be used include soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass.
[0013] If the roof glass 20 is inorganic glass and single-pane glass, it is preferable that the roof glass 20 is tempered glass. Tempered glass is glass on which a compressive stress layer has been formed, and may be either air-cooled tempered glass or chemically tempered glass. If the tempered glass is physically tempered glass (for example, air-cooled tempered glass), a compressive stress layer may be formed on the glass surface by an operation other than slow cooling, such as rapidly cooling a uniformly heated glass plate from a temperature near its softening point during bending, thereby generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the inside of the glass. If the tempered glass is chemically tempered glass, a compressive stress layer may be formed on the glass surface after bending by an ion exchange method or the like.
[0014] In the case where the roof glass 20 is laminated glass in which two glass plates are bonded together with a resin intermediate layer, both glass plates may be untempered glass, one may be tempered glass, or both may be tempered glass. If both are tempered glass, both may be air-cooled tempered glass, both may be chemically tempered glass, or one may be air-cooled tempered glass and the other may be chemically tempered glass.
[0015] The roof glass 20 may be formed from 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.
[0016] When the roof glass 20 is single-pane glass, the thickness of the roof glass 20 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 20, making it easier for the piston to vibrate. Also, when the roof glass 20 is single-pane glass, from the viewpoint of reducing the weight of the glass diaphragm module 10, the thickness of the roof glass 20 is preferably 10.0 [mm] or less, more preferably 7.0 [mm] or less, and even more preferably 5.0 [mm] or less.
[0017] When the roof glass 20 is made of laminated glass in which two glass plates are bonded together by a resin intermediate layer, the thickness of each of the pair of glass plates constituting the roof glass 20 is preferably 0.5 [mm] or more, more preferably 1.0 [mm] or more, and even more preferably 1.5 [mm] or more. The thicknesses of the pair of glass plates constituting the roof glass 20 may be the same or different, but from the viewpoint of stabilizing sound pressure, the same thickness is preferred. Furthermore, the total thickness of the roof glass 20 is preferably 1.0 [mm] or more, more preferably 2.0 [mm] or more, and even more preferably 3.0 [mm] or more. Also, from the viewpoint of reducing the weight of the glass diaphragm module 10, it is preferably 10.0 [mm] or less, more preferably 8.0 [mm] or less, and even more preferably 6.0 [mm] or less.
[0018] When the roof glass 20 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 its copolymer resins, etc. Alternatively, composite materials combining the above materials may be used. The above materials may be used individually or in combination of two or more types.Furthermore, tackifiers and plasticizers may be included to provide adhesion. The thickness of the intermediate layer may be, for example, 0.1 [μm] to 3.0 [mm], 1.0 [μm] to 2.8 [mm], or 3.0 [μm] to 2.6 [mm]. If the roof glass 20 is laminated glass, a dimmable film that electrically varies the visible light transmittance may be sandwiched between the two glass plates. Examples of dimmable films that can be used include TN (Twisted Nematic) type liquid crystal film, VA (Vertical Alignment) type liquid crystal film, polymer dispersed liquid crystal (PDLC) film, suspended particle device (SPD) film, polymer network liquid crystal (PNLC) film, guest host liquid crystal film, electrochromic material, and photochromic material. Glass on which an image is displayed on part or all of the glass is also conceivable. A liquid crystal film may be sandwiched as a method for displaying the image. Alternatively, a projection screen film may be sandwiched between the glass plates. Furthermore, some or all of the glass may be equipped with film-like solar cell elements for generating electricity from sunlight. To ensure visibility as a vehicle window, it is generally preferable to use transparent films with excellent transparency. These functions can be imparted not only by sandwiching the film between the glass plates, but also by directly microfabrication, printing, transfer, or application of the film to the glass surface, as long as the glass speaker's function is not compromised.
[0019] In this embodiment, the roof glass 20 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 20, 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.
[0020] The roof glass 20 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 20, but there may be at least a portion of the area where the light-shielding layer is not provided.
[0021] Furthermore, a defogger (not shown) may be formed on the interior surface of the roof glass 20 to clear fog (for anti-fogging). The defogger has a plurality of heater wires extending in the width direction of the roof glass 20 and a pair of bus bars extending vertically near both sides of the roof glass 20, with a plurality of heater wires formed between the pair of bus bars. The defogger is formed by printing and firing a silver paste containing silver powder and glass frit onto the surface of the roof glass 20.
[0022] Furthermore, if the roof glass 20 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 30 be mounted so as not to overlap with the conductive wires.
[0023] Furthermore, a coating film may be formed on the roof glass 20. The coating film may include 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.
[0024] Furthermore, the roof glass 20 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 roof glass, and is also called dark gray glass. In the roof glass 20, the privacy glass is Fe 2 O 3 This can be achieved by adjusting the total iron content converted to iron. The visible light transmittance of privacy glass can be adjusted to approximately 40-50% when the plate thickness is 1.8 mm, and approximately 30-45% when the plate thickness is 2.0 mm.
[0025] A transducer 30 for vibrating the roof glass 20 is bonded to the main surface of the roof glass 20 on the side facing the interior space S1. Alternatively, the transducer 30 may be attached to the main surface of the roof glass 20 via a mounting member or the like.
[0026] (Vibrator) The vibrator 30 is bonded to the roof glass 20. The vibrator 30 is connected to a power supply via a vibrator-side harness 40, a connector 50, a fixing part 60, and a power supply-side harness 70, and is an actuator that vibrates the roof glass 20 in response to an input electrical signal. In this embodiment, the vibrator 30 is, as an example, a voice coil motor including a coil part and a magnetic circuit, with one of the coil part and the magnetic circuit fixed to the roof glass 20, and the other being arranged to move relative to the roof glass 20. When current flows through the coil part, vibration is generated by the interaction between the coil part and the magnetic circuit, causing the roof glass 20 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, and any actuator capable of transmitting the desired vibration to the roof glass 20 can be used, such as a piezo actuator or other actuators besides a voice coil motor.
[0027] (Connector) The connector 50 is connected to the transducer 30 via the transducer-side harness 40. The end of the transducer-side harness 40 is connected to the connector 50. As shown in Figure 2, the connector 50 has a housing 51 that forms the outer shell and a female terminal 52 housed inside the housing 51.
[0028] The housing 51 is rectangular in shape. The housing 51 has a space formed inside. The female terminal 52 and the connecting part 53 are housed inside the housing 51. A through hole is formed in a part of the housing 51 that connects the inside and the outside. The connecting plate part 52D of the female terminal 52 is inserted through the through hole.
[0029] The female terminal 52 is formed, for example, from an elastically deformable plate-shaped metal. The female terminal 52 contacts and is electrically connected to the male terminal 63 of the fixing part 60, which will be described later. The female terminal 52 has a roughly U-shaped cross-section. In detail, the female terminal 52 integrally includes a pair of opposing plate portions 52A, a connecting plate portion 52B that connects the ends of one side (upper side of the paper in Figure 2) of the pair of opposing plate portions 52A, a contact plate portion 52C that bends and extends from the other end (lower side of the paper) of one opposing plate portion 52A toward the other opposing plate portion 52A, and a connecting plate portion 52D that connects the connecting plate portion 52B to the transducer-side harness 40.
[0030] The contact plate portion 52C extends from the other end (bottom of the paper) of one opposing plate portion 52A toward the other opposing portion 52A (left side of the paper) and toward one side (top of the paper). The contact plate portion 52C is substantially arc-shaped and biased toward the other opposing portion 52B. The contact plate portion 52C is elastically deformable. The contact plate portion 52C is deformable like a leaf spring. Thus, the contact plate portion 52C is a spring contact.
[0031] The other opposing plate portion 52B (the opposing plate portion 52B to which the contact plate portion 52C is not connected) has a protrusion that projects toward the contact plate portion 52C at a position opposite to the contact plate portion 52C.
[0032] The female terminal 52 has the male terminal (connected portion) 63 of the fixing portion 60, which will be described later, sandwiched between the contact plate portion 52C and the protrusion. When the connector 50 and the fixing portion 60 are engaged, the female terminal 52 is in contact with the male terminal 63 and is electrically connected to the male terminal 63. When the female terminal 52 and the male terminal 63 are in contact, the female terminal 52 (especially the contact plate portion 52C) is elastically deformed.
[0033] The connecting plate portion 52D is fitted into the through hole of the housing 51. The female terminal 52 is supported by the housing 51 at the connecting plate portion 52D.
[0034] (Fixed part) As shown in Figure 1, the fixed part 60 engages with the connector 50 and is fixed to the vehicle component 11 (vehicle body). As shown in Figure 2, the fixed part 60 has an engaging part 61 that engages with the connector 50, a locking part 62 that locks to the vehicle component 11, a male terminal (connected part) 63 that is electrically connected to the connector 50, and a vibration damping member 64 that is attached to the locking part 62.
[0035] The engaging portion 61 is provided with an engaging recess 61A into which the connector 50 is inserted. The engaging portion 61 also has a through hole through which the male terminal 63 is inserted. The engaging portion 61 has a mounting portion 61B to which the locking portion 62 is attached. The mounting portion 61B has a roughly L-shaped cross-section and engages with the locking portion 62.
[0036] As shown in Figures 2 and 3, the locking portion 62 integrally comprises a clip portion 66 that locks onto the vehicle component 11 and a support portion 67 that supports the mounting portion 61B of the engaging portion 61.
[0037] The clip portion 66 is made of an elastically deformable material. Examples of materials for the clip portion 66 include plastic. Specifically, examples include PA, PP, PE, ABS, PVC, PFA, PEEK, PC, POM, PS, PMMA, mPPE, PBT, PET, PPS, PSU, PAR, LCP, etc. The clip portion 66 integrally has a shaft portion 66A that is inserted through a through hole 11A formed in the vehicle component 11, and a tip portion 66B provided at the tip of the shaft portion 66A.
[0038] The shaft portion 66A is a cylindrical member centered on a central axis. The base end of the shaft portion 66A is connected to the support portion 67. The tip end of the shaft portion 66A is connected to the tip portion 66B. The tip portion 66B extends radially from the central axis of the shaft portion 66A toward the base end side (towards the support portion 67 side). That is, the diameter of the tip portion 66B decreases toward the tip side. Also, the tip end surface of the tip portion 66B is a flat surface. The tip portion 66B is located inside the vehicle component 11 when the fixing portion 60 is fixed to the vehicle component 11.
[0039] The support portion 67 is connected to the shaft portion 66A of the clip portion 66. The support portion 67 is provided with a recess 67A. The mounting portion 61B of the engaging portion 61 is fitted into the recess 67A. The support portion 67 and the tip portion 66B of the clip portion 66 are spaced apart.
[0040] The male terminal 63 is in contact with and electrically connected to the female terminal 52 of the connector 50. The male terminal 63 is inserted through a through hole formed in the engaging portion 61, and its tip is located inside the connector 50. The base end of the male terminal 63 is connected to the power supply harness 70.
[0041] The vibration damping member 64 is provided between the clip portion 66 and the support portion 67 of the locking portion 62. The vibration damping member 64 is a plate-shaped member with a through hole in its center. The shaft portion 66A of the locking portion 62 is inserted through the through hole. The vibration damping member 64 is provided so as to be in surface contact with the support portion 67. As shown in Figure 2, when the fixing portion 60 is not fixed to the vehicle component 11, the vibration damping member 64 is curved so as to move away from the support portion 67 from the center toward the outer circumference. Also, as shown in Figure 3, when the fixing portion 60 is fixed to the vehicle component 11, the outer circumference of the vibration damping member 64 is elastically deformed and becomes flat. Thus, the shape of the vibration damping member 64 changes depending on whether the fixing portion 60 is fixed to the vehicle component 11 or not.
[0042] The vibration damping member 64 damps the transmitted vibration. As the material of the vibration damping member 64, for example, natural rubber, nitrile rubber, silicone rubber, fluorine rubber, urethane rubber, acrylic rubber, isoprene rubber, styrene rubber, butadiene rubber, butyl rubber, ethylene - propylene rubber (EPM, EPDM), ethylene - vinyl acetate copolymer (EVA), urethane gel, silicone gel, acrylic gel, silica aerogel, acrylic foam tape, urethane foam tape, silicone foam tape, urethane sponge, etc. may be used. Also, as the material of the vibration damping member 64, foams of the above rubber group can be used. Incidentally, the vibration damping member 64 may be a cushioning material like a spring. When it is a cushioning material, the vibration damping member 64 may be formed of general engineering plastics such as ABS - based, PVC - based, PC - based, PP - based, PBT - based, PA66 - based, and PPS - based, PEEK - based, PPS - based, PET - based, and POM - based, etc., or may be formed of a metal including stainless steel, aluminum, titanium, steel, aluminum alloy, magnesium alloy, etc.
[0043] (Harness) As shown in FIG. 1, the vibrator - side harness 40 connects the vibrator 30 and the connector 50. That is, one end of the vibrator - side harness 40 is connected to the vibrator 30. Also, the other end of the vibrator - side harness 40 is connected to the connector 50. The vibrator - side harness 40 has a metal part through which electricity flows and a covering part that covers the metal part. The covering part is formed of a polymer material. The polymer material forming the covering part has, for example, a loss factor of 0.01 or more. The loss factor of the polymer material described above may be the loss factor with respect to vibration at 1 Hz under the condition of 23°C. The length of the vibrator - side harness 40 is, for example, 50 cm or less. Also, the thickness of the vibrator - side harness 40 is 2 sq or less and 0.1 sq or more. The power - supply - side harness 70 connects the fixing part 60 and a power supply (not shown).
[0044] (Function and Effect) According to this embodiment, the following functions and effects are achieved. In this embodiment, a fixing portion 60 for fixing the connector 50 to the vehicle component 11 (vehicle body) is provided. As a result, it is difficult for the connector 50 to vibrate due to the vibration transmitted through the vibrator side harness 40 from the vibrator 30. Therefore, damage to the connector 50 can be suppressed.
[0045] Also, in this embodiment, the fixing portion 60 and the connector 50 are engaged. As a result, it is more difficult for the connector 50 to vibrate, so damage to the connector 50 can be suppressed.
[0046] Also, in this embodiment, the connector 50 is inserted and an engaging recess that engages with the connector 50 is provided. As a result, the fixing portion 60 more suitably supports the connector 50. Therefore, it is more difficult for the connector 50 to vibrate, so damage to the connector 50 can be suppressed.
[0047] Also, in this embodiment, a vibration damping member 64 is provided between the fixing portion 60 and the vehicle component 11. As a result, the vibration of the fixing portion 60 is suppressed by the vibration damping member 64. Thus, since the vibration of the fixing portion 60 is suppressed, the vibration transmitted to the connector 50 is also suppressed. Therefore, damage to the connector 50 can be suppressed.
[0048] Also, in this embodiment, the connector 50 has a spring contact (specifically, the contact plate portion 52C) connected to the fixing portion 60. As a result, the connector 50 and the fixing portion 60 can be simply connected. Therefore, the workability of the connection work can be improved. On the other hand, the spring contact is easily damaged by vibration. Specifically, when vibration is transmitted to the connector 50, the spring contact may repeatedly vibrate and be damaged due to material fatigue. In this embodiment, since the vibration transmitted to the connector 50 can be suppressed, damage to the spring contact can be suppressed.
[0049] Furthermore, in this embodiment, the thickness of the transducer-side harness 40 is 2 sq mm or less and 0.1 sq mm or more. By making the thickness of the transducer-side harness 40 2 sq mm or less, the rigidity of the transducer-side harness 40 can be made relatively low, and the weight can be made relatively low. Therefore, the load acting on the connector 50 when the transducer-side harness 40 vibrates can be reduced. Thus, damage to the connector 50 can be suppressed. On the other hand, since the thickness of the transducer-side harness 40 is 0.1 sq mm or more, the strength of the transducer-side harness 40 can be maintained.
[0050] Furthermore, in this embodiment, the transducer-side harness 40 has a covering portion made of a polymer material. As a result, the covering portion dampens vibrations. Therefore, vibrations transmitted to the connector 50 are suppressed. Thus, damage to the connector 50 can be suppressed.
[0051] Furthermore, in this embodiment, the length of the transducer-side harness 40 from the transducer 30 to the connector 50 is set to 50 cm or less. By shortening the length of the transducer-side harness 40 in this way, the weight of the transducer-side harness 40 is reduced. Consequently, the load acting on the fixing part 60 via the connector 50 is reduced. Thus, damage to the fixing part 60 can be suppressed.
[0052] [Second Embodiment] Next, a second embodiment of the present disclosure will be described with reference to Figure 4. The glass diaphragm module according to this embodiment differs from the first embodiment in the position and structure of the fixed portion. The differences from the first embodiment will be described below, and the same reference numerals will be used for components identical to those in the first embodiment, and their detailed descriptions will be omitted.
[0053] As shown in Figure 4, the fixing portion 160 of the glass diaphragm module 110 according to this embodiment is not engaged with the connector 50. The fixing portion 160 is provided at an intermediate position on the transducer-side harness 40 and fixes the transducer-side harness 40 to the vehicle component 11 (vehicle body).
[0054] The fixing portion 160 supports the transducer-side harness 40 and is fixed to the vehicle component 11. The fixing portion 60 has a support portion 161 that supports the transducer-side harness 40 and a locking portion 162 that locks to the vehicle component 11.
[0055] The support portion 161 and the locking portion 162 are engaged. The support portion 161 and the locking portion 162 may be made as a single unit. The structure of the locking portion 162 is the same as that of the locking portion 62 in the first embodiment. Also, as in the first embodiment, a vibration damping member 64 may be attached to the locking portion 62.
[0056] The transducer-side harness 40 is fixed to the vehicle component 11 at an intermediate position by a fixing part 160. The transducer-side harness 40 integrally comprises a first portion 41 from the transducer 30 to the fixing part 160 and a second portion 42 from the fixing part 160 to the connector 50. The length of the first portion 41 is 50 cm or less. The length of the second portion 42 is also 50 cm or less. In this embodiment, the length of the first portion 41 is longer than the length of the second portion 42.
[0057] The connector 50 is connected to the member to be connected 180. The power supply harness 70 is connected to the member to be connected 180.
[0058] (Effects and Effects) This embodiment provides the following effects and effects. In this embodiment, the transducer-side harness 40 between the transducer 30 and the connector 50 is provided with a fixing part 160 that fixes it to the vehicle component 11 (vehicle body). As a result, vibrations transmitted from the transducer 30 through the transducer-side harness 40 are attenuated by the fixing part 160 provided between the transducer 30 and the connector 50. Therefore, vibrations from the transducer 30 are less likely to be transmitted to the connector 50. Consequently, damage to the connector 50 can be suppressed.
[0059] Furthermore, in this embodiment, the length of the transducer-side harness 40 from the transducer 30 to the fixing part 160 is set to 50 cm or less. By shortening the length of the transducer-side harness 40 in this way, the weight of the transducer-side harness 40 is reduced. Consequently, the load acting on the fixing part 160 is reduced. Thus, damage to the fixing part 160 can be suppressed.
[0060] Furthermore, in this embodiment, the length of the transducer-side harness 40 from the fixing part 160 to the connector 50 is set to 50 cm or less. By shortening the length of the transducer-side harness 40 in this way, the weight of the transducer-side harness 40 is reduced. Consequently, the load acting on the fixing part 160 is reduced. Thus, damage to the fixing part 160 can be suppressed.
[0061] [Third Embodiment] Next, a third 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 fixing destination and structure of the fixing part. The differences from the first embodiment will be described below, and the same reference numerals will be used for components identical to those in the first embodiment, and their detailed descriptions will be omitted.
[0062] As shown in Figure 6, the fixing portion 260 of the glass diaphragm module 210 according to this embodiment is attached to a vehicle component 15 (interior material). The vehicle component 15 may be, for example, an interior material that covers the outer periphery of the roof glass 20 and the vibrator 30 from below (vehicle interior S1 side).
[0063] The fixing portion 260 engages with the connector 50. The fixing portion 260 has an engaging portion 61 that engages with the connector 50 and a male terminal 63 (see Figure 2; not shown in Figure 5) that is electrically connected to the connector 50. The fixing portion 260 is attached to the vehicle component 15 by tape 270. Specifically, the fixing portion 260 is attached to the surface of the interior material that faces the roof glass 20. In addition, similar to the first embodiment, the fixing portion 260 may also include a locking portion 62 and a vibration damping member 64, and be attached to the vehicle component 15 by the locking portion 62.
[0064] This embodiment also achieves the same effects as the first embodiment described above.
[0065] 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.
[0066] For example, the second and third embodiments may be combined. That is, the fixing portion that is not engaged with the connector described in the second embodiment may be fixed to a vehicle component such as interior material, as described in the third embodiment.
[0067] For example, in the embodiments described above, the vibration damping member 64 is formed in the shape of a curved plate and is elastically deformable, but the disclosure is not limited thereto. For example, it may be formed in the shape of a flat plate, as shown in Figure 6, for example. In this case, the vibration damping member 164 is made of an elastic material. Specifically, the vibration damping member 164 is made of, for example, ethylene propylene diene rubber (EPDM).
[0068] Furthermore, although the glass diaphragm modules according to each embodiment described above have been applied to the roof glass located on the upper side of the vehicle, this disclosure is not limited thereto. 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.
[0069] Furthermore, although the embodiments described above describe an example in which the transducer 30 is directly bonded to the roof glass 20, the disclosure is not limited thereto. For example, the transducer 30 may be attached to the roof glass 20 via a mounting member (not shown) or a long rod (not shown).
