Description

Technical Field

[0001] This application belongs to the technical field of speaker brackets, speaker frames, and speakers. More specifically, it belongs to the technical field of speaker brackets, speaker frames, and speakers that include a structure for attaching a speaker to the outside (e.g., inside a vehicle door, etc.).

Background Art

[0002] Generally, in-vehicle speakers include speakers that are attached during vehicle manufacturing and speakers that are removed, for example, after vehicle sales and newly attached, which were attached during manufacturing.

[0003] Here, in the latter case, since the configuration or structure of the part of the vehicle where the speaker is attached is adapted to the configuration or structure for attachment in the speaker that was attached during manufacturing, it may not match the configuration or structure for attachment in the newly attached speaker. Therefore, in such a case, generally, a separate attachment part called a bracket (or attachment or adapter. Hereinafter, these will be simply referred to as "bracket" for representative purposes) is interposed between the speaker and the vehicle, and then the newly attached speaker is attached to the position of the original speaker. As a prior art document regarding the structure of such a bracket, for example, the following Patent Document 1 can be cited. In the technology described in this Patent Document 1, it has a configuration including a plurality of mounting plates that horizontally protrude outward from the outer periphery of the speaker frame and a cutting line provided at the base end of the plurality of mounting plates. And depending on the structure of the newly attached part, when the mounting plate is unnecessary, the speaker is attached after folding off the mounting plate from the cutting line.

Mode for Carrying Out the Invention

[0011] Next, the embodiments for carrying out the present application will be described with reference to FIGS. 1 to 3. Note that FIG. 1 is an external perspective view showing the usage state and the like of the speaker bracket of the embodiment and the examples, FIG. 2 is a front view showing the configuration of the speaker bracket, and FIG. 3 is a rear perspective view showing the configuration of the speaker bracket. Here, in the embodiments and examples described below, the surface of the speaker bracket on which the speaker to be described later is fixed and supported is defined as the front, and the surface fixed to the inner lining to be described later in the speaker bracket to which the speaker is fixed is defined as the rear. Also, in FIG. 1, only an external perspective view of the outline of the speaker bracket of the embodiment is shown using a broken line.

[0012] As shown in FIG. 1, the speaker bracket 1 according to the embodiment is a member that enables the speaker SP to be attached to the inner lining BD of doors of various vehicle types by being interposed between the inner lining BD of the door of the vehicle and the speaker SP to be newly attached. More specifically, the speaker SP is fixed to the speaker bracket 1 while being supported by the mounting holes p1 to p4 of the speaker SP, and the speaker bracket 1 in this state is fixed to the speaker hole BH of the inner lining BD using the mounting holes h1 and h2 of the inner lining BD. Therefore, the speaker bracket 1 is provided with two types of fixing holes: a speaker fixing hole for supporting and fixing the speaker SP using the mounting holes p1 to p4, and a bracket fixing hole for fixing the speaker bracket 1 itself to which the speaker SP is fixed to the speaker hole BH using the mounting holes h1 and h2. At this time, since the number and positions of the mounting holes h1 provided on the peripheral edge of the speaker hole BH and the like vary depending on the vehicle type to which the speaker SP is attached, a plurality of bracket fixing holes are provided in the speaker bracket 1 according to the embodiment so that each assumed vehicle type can be correspondingly supported using one type of speaker bracket 1.

[0013] That is, as shown in FIGS. 1 to 3, the speaker bracket 1 according to the embodiment includes a support portion 10 that supports the speaker SP, and a mounting member 20 that is used to externally attach the speaker SP supported by the support portion 10. The mounting member 20 is provided on the support portion 10, and a plurality of grooves 201 and 202 having different extending directions are continuously formed at the base B of the mounting member 20 that connects the mounting member 20 and the support portion 10.

[0014] As described above, according to the configuration of the speaker bracket 1 of the embodiment, a plurality of grooves 201 and 202 having different extending directions are continuously formed at the base of the mounting member 20 used to externally attach the speaker SP. Therefore, it is possible to achieve both ensuring the strength when attaching the speaker SP externally using the mounting member 20 and improving the workability in separating the mounting member when attaching the speaker SP externally without using the mounting member 20.

Example

[0015] Next, regarding specific examples corresponding to the above-described embodiments, in addition to FIGS. 1 to 3, FIGS. 4 to 7 will be used for explanation. The examples described below are examples when the embodiments are applied to a speaker bracket used to remove a speaker that was originally fixed and fix a new speaker SP at the removed position. At this time, in FIGS. 4 to 7, for each component of the example corresponding to each component in the speaker bracket 1 of the embodiment shown in FIGS. 1 to 3, the same component numbers as those of the components in the speaker bracket 1 of the embodiment are used.

[0016] First, regarding the speaker bracket of the example, its overall structure will be described with reference to FIG. 4. Note that FIG. 4 is a front perspective view showing the configuration of the speaker bracket of the example. In addition, the speaker bracket of the example described below is formed by integral molding using, for example, resin as a material.

[0017] As shown in Fig. 4, the speaker bracket 1 of the embodiment corresponding to the embodiment has, on the periphery of a circular frame-shaped support portion 10 that conforms to the outer shape of the speaker SP, a plurality of speaker fixing holes SL1 to SL4, a plurality of bracket fixing holes HL1 to HL8 and bracket fixing holes HS1 to HS8, the attachment members 20 and 21 of the embodiment, and positioning protrusions 25 to 28 when fixing the speaker SP to the speaker bracket 1. In this configuration, the bracket fixing holes HL1 to HL8 are elongated bracket fixing holes formed along the radial direction of the support portion 10 in the protruding portions 11 to 16 that protrude radially outward from the outer peripheral edge portion of the support portion 10, respectively. On the other hand, the bracket fixing holes HS1 to HS8 are circular bracket fixing holes formed in the peripheral portion of the support portion 10. These bracket fixing holes HL1 to HL8 and bracket fixing holes HS1 to HS8 are used for fixing the speaker bracket 1 to the position of the speaker hole BH of the inner lining BD according to the number and position of the mounting holes h1, etc. of the inner lining BD. In contrast, the speaker fixing holes SL1 to SL4 are speaker fixing holes used for fixing the speaker SP and the speaker bracket 1, and are formed in the support portion 10 in accordance with the number and position of the attachment portions p1 to p4 (see Fig. 1) of the speaker SP. Further, the protrusions 25 to 28 are provided on the peripheral portion of the support portion 10 as protrusions having positions and shapes that enable the above positioning.

[0018] In addition to these, on both sides of the protruding portion 14 at the outer peripheral edge portion of the support portion 10, the attachment members 20 and 21 of the embodiment for locking (i.e., hooking) and fixing the speaker bracket 1 (i.e., hooking the speaker bracket 1 on a part of the inner peripheral edge portion of the speaker hole BH in a specific vehicle model) are formed. The detailed configuration of these attachment members 20 and 21 will be described in detail later with reference to Figs. 3, 5, and 6.

[0019] On one side, on the front surface of each of the protrusions 11 to 16, separation grooves L1 to L16 corresponding to the number and positions of mounting holes h1, etc. of the speaker holes BH in the vehicle type assumed to have the speaker bracket 1 fixed thereto are formed (that is, engraved on the surface). Each of these separation grooves L1 to L16 is a separation groove for separating the portion outside the separation grooves L1 to L16 from the support portion 10 according to the assumed vehicle type. This separation is performed, for example, by cutting the separation groove or folding off the outside portion.

[0020] Next, the detailed configuration of the attachment members 20 and 21 of the embodiment will be described more specifically with reference to FIGS. 3, 5, and 6. Note that FIG. 5 is an enlarged back view showing the configuration of the attachment member of the embodiment, and FIG. 6 is an enlarged side view showing the configuration of the attachment member. At this time, FIG. 5(a) is an enlarged side view of the attachment member 20 viewed from the A direction in FIG. 3. Also, in FIG. 5(b), separation grooves 201 and 202 and a bending point IP, which will be described later and are formed on the back surface side of the attachment member 20, are shown by broken lines. Further, the attachment members 20 and 21 are symmetric in position and shape with respect to the axis of symmetry being the radius of the support portion 10 passing through the bracket fixing holes HL5 and HS4 of the protrusion 14. Therefore, in the following description, the detailed configuration of the attachment member 20 will be described, representing the attachment members 20 and 21.

[0021] Fig. 5(a) shows an enlarged rear view, Fig. 5(b) shows an enlarged front view, Fig. 6(a) shows an enlarged side view, and Fig. 6(b) shows an enlarged rear perspective view. As shown, the mounting member 20 of the embodiment is composed of a locking portion 200 provided with reinforcing ribs 203 and 204 on the back surface and reinforcing ribs 205 and 206 on the front surface. And on the back surface side of the base B of the mounting member 20 (that is, the base B of the mounting member 20 that is on the same plane as the surface on the back side of the support portion 10 and connects the support portion 10 and the mounting member 20) for connecting the mounting member 20 having the locking portion 200 and the support portion 10, separation grooves 201 and 202 for separating the mounting member 20 from the support portion 10 are formed on its surface (that is, engraved on the surface). This separation groove 201 corresponds to an example of the groove 201 of the embodiment, and the separation groove 202 corresponds to an example of the groove 202 of the embodiment. At this time, the separation grooves 201 and 202 are linear continuous grooves bent at the bending portion IP, and their cross sections are substantially V-shaped. And the mounting member 20 can be separated from the support portion 10 as needed by cutting the separation grooves 201 and 202 or folding the mounting member 20 from the separation grooves 201 and 202. With this configuration, when attaching the speaker SP to the outside (for example, the inner lining BD of a car door), the mounting member 20 can be separated from the speaker bracket 1 according to the shape of the mounting portion on the outside.

[0022] Note that the depth of each of the separation grooves 201 and 202 itself is preferably set to a depth corresponding to about 1% to 30% of the thickness of the base B from the viewpoint of the mounting strength of the speaker SP using the mounting member 20 and the mounting member 21. Also, the length, width, and bending angle at the bending portion IP of each of the separation grooves 201 and 202 are such that the shape of the position on the support portion 10 where the mounting member 20 was provided after the mounting member 20 is separated is along the shape of the inner peripheral edge of the position facing the position on the support portion 10 where the mounting member 20 was provided in the speaker hole BH where the speaker bracket 1 is fixed without using the mounting member 20.

[0023] Next, the usage mode of the speaker bracket 1 of the embodiment will be specifically described with reference to FIG. 7. Note that FIG. 7 is a front view for explaining the usage mode of the speaker bracket.

[0024] For example, when fixing the speaker bracket 1 to the speaker hole BH of the first vehicle model, the speaker bracket 1 is used such that the attachment members 20 and 21 remain and are located, for example, vertically downward from the center of the speaker bracket 1 as shown in the front view of FIG. 7(a). Then, by the locking by the attachment members 20 and 21 and the fixing using, for example, the bracket fixing hole HL1, the speaker bracket 1 is fixed to the speaker hole BH. At this time, other bracket fixing holes such as HS2 are not used.

[0025] Also, for example, when fixing the speaker bracket 1 to the speaker hole BH of the second vehicle model, the speaker bracket 1 is used as the speaker bracket 1-1 in which the outer portions are separated from the separation grooves L3, L6, L9, L10, L12, and L15, as shown in the front view of FIG. 7(b). At this time, the attachment members 20 and 21 are also separated and used together. Then, the bracket fixing holes HS2, HS4, HS6, and HS8 are used as actual bracket fixing holes, and other bracket fixing holes such as HL1 are not used.

[0026] Furthermore, for example, when fixing the speaker bracket 1 to the speaker hole BH of the third vehicle model, the speaker bracket 1 is used as the speaker bracket 1-2 in which the outer portions are separated from the respective separation grooves L2, L4, L9, and L12, as shown in the front view in Fig. 7(c). At this time, the attachment member 20 and the attachment member 21 are also separated and used together. Then, the bracket fixing holes HL1, HL2, HL5, and HL8 are used as the actual bracket fixing holes, and the other bracket fixing holes HS2 etc. are not used.

[0027] Furthermore, for example, when fixing the speaker bracket 1 to the speaker hole BH of the fourth vehicle model, the speaker bracket 1 is used as the speaker bracket 1-3 in which the outer portions are separated from the respective separation grooves L1, L2, L4, L5, L9, L11, L12, and L16, as shown in the front view in Fig. 7(d). At this time, the attachment member 20 and the attachment member 21 are also separated and used together. Then, the bracket fixing holes HL1, HL2, HL5, and HL8 are used as the actual bracket fixing holes, and the other bracket fixing holes HS2 etc. are not used.

[0028] Also, for example, when fixing the speaker bracket 1 to the speaker hole BH of the fifth vehicle model, the speaker bracket 1 is used as the speaker bracket 1-4 in which the outer portions are separated from the respective separation grooves L2, L4, L6, L8, L10, L13, and L15, as shown in the front view in Fig. 7(e). At this time, the attachment member 20 and the attachment member 21 are also separated and used together. Then, the bracket fixing holes HL1, HL3, and HS7 are used as the actual bracket fixing holes, and the other bracket fixing holes HS2 etc. are not used.

[0029] Finally, for example, when fixing the speaker bracket 1 to the speaker hole BH of the sixth vehicle model, the speaker bracket 1 is used as the speaker bracket 1-5 in which the outer portions are separated from the respective separation grooves L2, L4, L6, L9, L10, L12, and L15, as shown in the front view thereof in Fig. 7(f). At this time, the attachment member 20 and the attachment member 21 are also separated and used together. Then, the bracket fixing holes HS8, HS3, and HS5 are used as actual bracket fixing holes, and the other bracket fixing holes HL1, etc. are not used.

[0030] In addition, in Figs. 2, 4, and 7, the separation grooves L1 to L16 are described as linear, but these may be curved separation grooves.

[0031] As described above, according to the configuration of the speaker bracket 1 of the embodiment, a plurality of separation grooves 201 and 202 having different extending directions are continuously formed on the base B of the attachment member 20 used for attaching the speaker SP to the speaker hole BH. Therefore, it is possible to achieve both ensuring the strength when attaching the speaker SP to the inner lining BD using the attachment member 20 and improving the workability in separating the attachment member when attaching the speaker SP to the inner lining BD without using the attachment member 20.

[0032] Further, since the separation grooves 201 and 202 are a plurality of linear grooves connected at one bending point IP, the separation grooves 201 and 202 can be formed in a simple process while achieving both maintaining the strength and improving the workability.

[0033] Furthermore, since the overall shapes of the separation grooves 201 and 202 as viewed from a direction perpendicular to the extending directions of the separation grooves 201 and 202 (see FIG. 5) are shaped to correspond to the shape of the speaker hole BH to which the speaker SP is attached via the speaker bracket 1 after the attachment member 20 is separated, the speaker SP can be surely attached to a necessary region using the speaker bracket 1 after the attachment member 20 is separated.

[0034] Furthermore, since the separation grooves 201 and 202 are formed only on one surface (i.e., the surface on the back side) of the plate-shaped base B (see FIGS. 5 and 6), sufficient strength can be ensured when attaching the speaker SP to the outside using the attachment member 20.

[0035] [Modification Example] Next, a modification example corresponding to the embodiment will be described with reference to FIGS. 8 and 9. FIGS. 8 and 9 are enlarged rear views showing the configurations of the attachment members of the respective modification examples. Also, in FIGS. 8 and 9, for the configurations similar to the attachment member 20 and the support portion 10 of the embodiment, the same member numbers are used and detailed descriptions thereof are omitted.

[0036] (I) First Modification Example First, the configuration of the mounting member of the first modification will be described with reference to FIG. 8(a). As shown in the enlarged rear view of FIG. 8(a), in the mounting member 20-1 of the first modification, the separation groove continuously formed via the bending portion IP in the separation groove 202 similar to the embodiment is not linear, but a curved separation groove 210 protruding toward the mounting member 20 side. This separation groove 210 corresponds to another example of the groove 201 in the embodiment. Since the configuration of the mounting member 20-1 of the other first modifications is the same as that of the mounting member 20 in the embodiment, the detailed description is omitted. According to the configuration of the mounting member 20-1 of such a first modification, when the speaker SP is mounted using the mounting member 20 and the mounting member 21, the vicinity of the central portion of the separation groove 210 will protrude downward in the vertical direction (see the usage mode shown in FIG. 7(a)). Thereby, when, for example, rain enters the back side of the speaker SP after mounting, even if the moisture due to the rain enters from the right side in FIG. 8(a) of the separation groove 210, it can be stored in the protruding portion, and it can be suppressed that it drips downward (that is, as a result, rain leakage occurs). In the curved separation groove 210 and the like of the first to fourth modifications, the direction of the tangent of the curve is the extending direction as the separation groove 210 and the like.

[0037] (II) Second Modification Example Next, the configuration of the mounting member of the second modification will be described with reference to FIG. 8(b). As shown in the enlarged rear view of FIG. 8(b), in the mounting member 20-2 of the second modification, a curved separation groove 210 similar to that of the first modification and a curved separation groove 211 protruding toward the mounting member 20 side similar to the separation groove 210 are continuously formed in the base B via the bending portion IP. This separation groove 211 corresponds to another example of the groove 202 in the embodiment. Since the configuration of the mounting member 20-2 of the other second modifications is the same as that of the mounting member 20-1 in the first embodiment, the detailed description is omitted. Note that the separation groove 210 of the mounting member 20-2 of the second modification also has the same rain leakage suppressing effect as the separation groove 210 of the first modification.

[0038] (III) Third Modification Example Next, the configuration of the attachment member of the third modification will be described with reference to Fig. 9(a). As shown in the enlarged rear view in Fig. 9(a), the attachment member 20-3 of the third modification does not have the bent portion IP where the separation groove 201 and the separation groove 202 of the embodiment are connected, and only the curved separation groove 212 is formed. This separation groove 212 corresponds to yet another example of the groove 201 of the embodiment and yet another example of the groove 202, respectively. Since the configuration of the attachment member 20-3 of the other third modification is the same as that of the attachment member 20 of the embodiment, detailed description thereof will be omitted.

[0039] (IV) Fourth Modification Example Finally, the configuration of the attachment member of the fourth modification will be described with reference to Fig. 9(b). As shown in the enlarged rear view in Fig. 9(b), the attachment member 20-4 of the fourth modification does not have the bent portion IP, similar to the attachment member 20-3 of the third embodiment, and only the curved separation groove 213 having a shape different from the separation groove 212 of the third embodiment is formed. This separation groove 213 corresponds to yet another example of the groove 201 of the embodiment and yet another example of the groove 202, respectively. Since the configuration of the attachment member 20-4 of the other fourth modification is the same as that of the attachment member 20 of the embodiment, detailed description thereof will be omitted.

[0040] As described above for each, according to the configuration of the attachment members 20-1 etc. of each modification, since the separation grooves 210 etc. include curved grooves, it is possible to form the separation grooves 210 etc. in a simple process while achieving both strength maintenance and workability improvement.

[0041] Also, according to the configurations of the attachment member 20-2 of the second modification, the attachment member 20-3 of the third modification, and the attachment member 20-4 of the fourth modification, since the entire separation groove 210 to the separation groove 213 is a curved groove that is curved, it is possible to form the separation groove in a simple process while achieving both strength maintenance and workability improvement.

[0042] In the above-described embodiments, first modification example, and second modification example, the bending portion IP was only at one location. However, a separation groove may be constituted by a linear or curved groove having a plurality of bending points. Further, although the cross-section of the separation groove 201 or the like is substantially V-shaped, alternatively, the separation groove 201 or the like may be constituted by a groove having a rectangular cross-section with a bottom surface along its extending direction, a groove having a semi-circular cross-section, or a groove having a U-shaped cross-section.

[0043] In the above-described embodiments and each modification example, the case where the separation groove 201 or the like is formed on the back surface side of the base B of the attachment member 20 has been described. However, alternatively, the separation groove 201 or the like may be formed on the front surface of the base B, the support portion 10, or the attachment member 20 and the attachment member 21.

[0044] Furthermore, in the above-described embodiments and each modification example, the case where the present application is applied to the speaker bracket 1 for fixing the speaker SP to the inner lining BD with the speaker SP interposed therebetween has been described. However, alternatively, the frame-shaped speaker frame itself for supporting the diaphragm of the speaker attached to the inner lining BD, or the configuration of the outer peripheral edge itself of the speaker may be the same as the attachment member 20 and the attachment member 21 of the above embodiment, or the speaker bracket 1 including the attachment member 20-1 or the like of each of the above modification examples. Also in this case, the same effects as those of the above embodiment or each of the above modification examples can be obtained.

[0045] Furthermore, in the above-described embodiments and each modification example, the case where the back surface of the peripheral portion of the support portion 10 is planar has been described (see FIG. 3). However, alternatively, a lightening cutout may be formed at a position other than the position of the bracket fixing hole HS1 or the like on the back surface of the peripheral portion.

[0046] In the above-described embodiments and each modification example, the entire speaker bracket 1 is formed by integral molding using resin. However, alternatively, the material may be partially different.
