CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a U.S. National Stage entry of PCT Application No. PCT/JP2019/020896, filed on May 27, 2019, which claims priority to JP Application No. 2018-103615, filed May 30, 2018. The contents of the foregoing are incorporated by reference. 
     TECHNICAL FIELD 
     The present application belongs to the technical fields of speaker brackets, speaker frames, and speakers. More specifically, the present application belongs to the technical fields of speaker brackets, speaker frames, and speakers, including a structure for attaching a speaker to an external portion (for example, the inner side of a vehicle door or the like). 
     BACKGROUND ART 
     In general, an in-vehicle speaker is a speaker that is installed at the time of manufacture of a vehicle, or a speaker that is newly installed when the speaker installed at the time of manufacture is removed after the sale of the vehicle, for example. 
     Here, in the latter case, the configuration or the structure of the portion to which the speaker is attached in the vehicle is designed in conformity with the configuration or the structure for installation in the speaker installed at the time of manufacture, and might not match a configuration or a structure for installing a speaker to be newly installed. Therefore, in such a case, an independent mounting component called a bracket (or an attachment or an adapter; hereinafter, these components will be simply called “brackets”) is normally interposed between the speaker and the vehicle, and the speaker to be newly installed is then installed at the position of the original speaker. Examples of prior art documents relating to the structure of such a bracket include Patent Document 1 shown below. A configuration according to the technology disclosed in Patent Document 1 includes a plurality of mounting plates horizontally protruding outward in parallel to the outer circumference of the frame of the speaker, and cutting lines formed on the base edge portions of the plurality of mounting plates. Further, in a case where any mounting plate is not required depending on the structure of the portion to which a speaker is to be newly attached, the speaker is installed after the mounting plates are bent and removed from the above cutting lines.

     SUMMARY OF THE INVENTION 
     Problem to be Solved by the Invention 
     The above cutting lines disclosed in Patent Document 1 are formed with a plurality of cutting holes arranged to form one line along the above outer circumference of the frame. In a case where the speaker is installed with the mounting plates disclosed in Patent Document 1, however, the strength might become insufficient due to the above cutting holes. Therefore, in a case where the speaker disclosed in Patent Document 1 is installed in another structure (a vehicle, for example), there is a problem that maintaining the strength for installing a speaker with mounting plates and increasing the workability in bending and removing the mounting plates when a speaker is installed without any mounting plate cannot be incompatible. 
     Therefore, the present application has been made in view of the above problem, and one example objective thereof is to provide a speaker bracket, a speaker frame, and a speaker that are capable of both maintaining the strength for installing a speaker with mounting plates, and increasing the workability in bending and removing the mounting plates or the like when a speaker is installed without any mounting plate.

     MODES FOR CARRYING OUT THE INVENTION 
     Next, a mode for carrying out the present application is described, with reference to  FIGS. 1 to 3 . Note that  FIG. 1  is an external perspective view showing a usage state and the like of a speaker bracket of an embodiment and an example.  FIG. 2  is a front view showing the configuration of the speaker bracket.  FIG. 3  is a back-side perspective view of the speaker bracket. Here, in the embodiment and example described below, the surface of each speaker bracket to which the speaker described later is fixed and is thus supported is the front surface, and the surface of the speaker bracket fixed to the lining described later is the back surface, with the speaker being fixed to the speaker bracket.  FIG. 1  is also shows an external perspective view of only the outline of the speaker bracket of an embodiment, using dashed lines. 
     As shown in  FIG. 1 , a speaker bracket  1  of an embodiment is a member that is interposed between the lining BD of a vehicle door and the speaker SP to be newly installed, for example. With this arrangement, the speaker SP can be attached to the lining BD of a door of a vehicle of any kind. More specifically, the speaker SP is secured to the speaker bracket  1  while being supported with mounting holes p 1  to p 4 , and the speaker bracket  1  in this state is secured to a speaker hole BH of the lining BD with mounting holes h 1  and h 2  of the lining BD. Therefore, the speaker bracket  1  has two kinds of securing holes: speaker securing holes for supporting and securing the speaker SP with the mounting holes p 1  to p 4 , and bracket securing holes for securing the speaker bracket  1  having the speaker SP fixed thereto to the speaker hole BH with the mounting holes h 1  and h 2 . At this stage, the number and the positions of the mounting hole h 1  and the like formed at the circumferential edge portion of the speaker hole BH vary depending on the model of the vehicle in which the speaker SP is installed. Therefore, a plurality of bracket securing holes are formed in the speaker bracket  1  of the embodiment, so that one kind of the speaker bracket  1  can be used for various conceivable models of vehicles. 
     That is, as shown in  FIGS. 1 to 3 , the speaker bracket  1  of the embodiment includes: a support portion  10  that supports the speaker SP; and a mounting member  20  that is to be used for attaching the speaker SP supported by the support portion  10  to an external portion, and is formed on the support portion  10 . A plurality of grooves  201  and  202  having different extending directions is continuously formed on a base portion B of the mounting member  20 , the base portion B connecting the mounting member  20  and the support portion  10 . 
     As described above, in the configuration of the speaker bracket  1  of the embodiment, the plurality of grooves  201  and  202  having different extending directions is continuously formed on the base portion of the mounting member  20  to be used for attaching the speaker SP to an external portion. Thus, it is possible to both maintain the strength for attaching the speaker SP to an external portion with the mounting member  20 , and increase the workability in detaching the mounting member when the speaker SP is attached to an external portion without the mounting member  20 . 
     Exemplary Embodiments 
     Next, a specific example corresponding to the above embodiment is described, with reference to  FIGS. 4 to 7 , in addition to  FIGS. 1 to 3  described above. Note that the example described below is an example in a case where the embodiment is applied to a speaker bracket to be used for detaching the originally secured speaker and securing a new speaker SP to the position from which the speaker has been detached. In this case, in  FIGS. 4 to 7 , the same reference numerals as those for the respective components in the speaker bracket  1  of the embodiment are used for the respective components of the example corresponding to the respective components of the speaker bracket  1  of the embodiment shown in  FIGS. 1 to 3 . 
     First, the overall structure of a speaker bracket of the example is 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. Further, the speaker bracket of the embodiment described below is formed by integral molding using a resin as a material, for example. 
     As shown in  FIG. 4 , the speaker bracket  1  of the example corresponding to the embodiment has, on the circumferential portion of a circular frame-like support portion  10  that matches the outer shape of the speaker SP, a plurality of speaker securing holes SL 1  to SL 4 , a plurality of bracket securing holes HL 1  to HL 8  and bracket securing holes HS 1  to HS 8 , mounting members  20  and  21  of the example, and protrusions  25  to  28  for positioning when the speaker SP is secured to the speaker bracket  1 . In this configuration, the bracket securing holes HL 1  to HL 8  are long bracket securing holes formed in protruding portions  11  to  16  protruding outward from the outer circumferential edge portion of the support portion  10 , each bracket securing hole extending in the radial direction of the support portion  10 . Meanwhile, the bracket securing holes HS 1  to HS 8  are bracket fixing holes in the form of round holes formed in the circumferential portion of the support portion  10 . These bracket securing holes HL 1  to HL 8  and bracket securing boles HS 1  to HS 8  are used for securing the speaker to the position of the speaker hole BH of the lining BD, depending on the number and the positions of the mounting hole h 1  and the like of the lining BD. On the other hand, the speaker securing holes SL 1  to SL 4  are the speaker securing holes to be used for securing the speaker SP to the speaker bracket  1 , and are formed in the support portion  10  in accordance with the number and the positions of mounting portions p 1  to p 4  (see  FIG. 1 ) of the speaker SP. Further, the protrusions  25  to  28  are formed as protrusions that have positions and shapes with which the above positioning can be performed, in the circumferential portion of the support portion  10 . 
     In addition to these, the mounting members  20  and  21  of the example are formed on both sides of the protruding portion  14  in the outer circumferential edge portion of the support portion  10 . The mounting members  20  and  21  are designed for locking and securing the speaker bracket  1  (that is, hooking the speaker bracket  1  on part of the inner circumferential edge portion of the speaker hole BH of a certain vehicle model). The specific configuration of these mounting members  20  and  21  will be described later in detail, with reference to  FIGS. 3, 5, and 6 . 
     Meanwhile, on the surfaces of the respective protruding portions  11  to  16  on the front side, detaching grooves L 1  to L 16  are formed (or are etched in the surfaces) in accordance with the number and the positions of the mounting hole h 1  and the like of the speaker hole BH in any of the conceivable vehicle models to which the speaker bracket  1  can be secured. Each of these detaching grooves L 1  to L 16  is a detaching groove for detaching the portion outside the detaching grooves L 1  to L 16  from the support portion  10 , depending on the conceivable vehicle models. This detaching is performed by cutting the detaching grooves, or bending and removing the outer portion, for example. 
     Next, the specific configuration of the mounting members  20  and  21  of the example is described in greater detail, with reference to  FIGS. 3, 5, and 6 . Note that  FIG. 5  is an enlarged back view and the like showing the configuration of mounting member of the example.  FIG. 6  is an enlarged side view and the like showing the configuration of the mounting member. In this case,  FIG. 5( a )  is an enlarged side view of the mounting member  20  as viewed from the direction A defined in  FIG. 3 . Further, in  FIG. 5( b ) , detaching grooves  201  and  202  and a bend point IP, which will be described later, formed on the back surface side of the mounting member  20  are indicated by dashed lines. Further, the mounting members  20  and  21  have line-symmetric positions and shapes, with the axis of symmetry being the radius of the support portion  10  extending through the bracket securing holes HL 5  and HS 4  of the protruding portion  14 . Therefore, in the description below, the specific configuration of the mounting member  20  will be described as a typical configuration of the mounting members  20  and  21 . 
       FIG. 5( a )  shows an enlarged back view,  FIG. 5( b )  shows an enlarged front view,  FIG. 6( a )  shows an enlarged side view, and  FIG. 6( b )  shows an enlarged back perspective view of the mounting member  20  of the example. As shown in these drawings, the mounting member  20  is formed with a locking portion  200  that has reinforcement ribs  203  and  204  formed on the back surface, and reinforcement ribs  205  and  206  formed on the front surface. Further, on the back surface side of the base portion B of the mounting member  20  that connects the mounting member  20  having the locking portion  200  to the support portion  10  (that is, the base portion B of the mounting member  20  that exists in 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 ), the detaching grooves  201  and  202  for detaching the mounting member  20  from the support portion  10  are formed on the surface (or are etched in the surface). The detaching groove  201  corresponds to an example of the groove  201  of the embodiment, and the detaching groove  202  corresponds to an example of the groove  202  of the embodiment. In this case, the detaching grooves  201  and  202  are linear continuous grooves that are bent at the bend portion IP, and its cross-section is substantially a V-shaped cross-section. Further, the detaching grooves  201  and  202  are cut, or the mounting member  20  is bent and removed from the detaching grooves  201  and  202 , so that the mounting member  20  can be detached from the support portion  10  as necessary. With this configuration, when the speaker SP is attached to an external portion (the lining BD of a vehicle door, for example), the mounting member  20  can be detached from the speaker bracket  1  in accordance with the shape of the mounting portion of the external portion. 
     Note that the depth of each of the detaching grooves  201  and  202  is preferably a depth equivalent to 1% to 30% of the thickness of the base portion B, from the viewpoint of the mounting strength of the speaker SP with the mounting members  20  and  21 , for example. Further, the length, the width, and the bending angle at the bend portion IP of each of the detaching grooves  201  and  202  are set so that the position to which the mounting member  20  was attached in the support portion  10  has, after the detachment of the mounting member  20 , a shape in conformity with the shape of the inner circumferential edge of the position facing the position of the support portion  10  to which the mounting member  20  was attached in the speaker hole BH to which the speaker bracket  1  is secured without the mounting member  20 . 
     Next, usage modes of the speaker bracket  1  of the example are specifically described, with reference to  FIG. 7 . Note that  FIG. 7  is front views each for explaining a usage mode of the speaker bracket. 
     For example, in a case where the speaker bracket  1  is secured to the speaker hole BH of a first vehicle model, the speaker bracket  1  leaves the mounting members  20  and  21  thereon, and is used so that the mounting members  20  and  21  are positioned below the center of the speaker bracket  1  in a vertical direction, for example, as shown in the front view in  FIG. 7( a ) . The speaker bracket  1  is then secured to the speaker hole BH by the locking with the mounting members  20  and  21 , and the securement using the bracket securing hole HL 1 , for example. In this case, the other bracket securing hole HS 2  and the like are not used. 
     Also, in a case where the speaker bracket  1  is secured to the speaker hole BH of a second vehicle model, for example, the speaker bracket  1  is used as a speaker bracket  1 - 1  having its outer portion detached from each of the detaching grooves L 3 , L 6 , L 9 , L 10 , L 12 , and L 15 , as shown in the front view in  FIG. 7( b ) . In this case, the mounting members  20  and  21  described above are also detached and are then used. The bracket securing holes HS 2 , HS 4 , HS 6 , and HS 8  are then used as the actual bracket securing holes, and the other bracket securing hole HL 1  and the like are not used. 
     Further, in a case where the speaker bracket  1  is secured to the speaker hole BH of a third vehicle model, for example, the speaker bracket  1  is used as a speaker bracket  1 - 2  having its outer portion detached from each of the detaching grooves L 2 , L 4 , L 9 , and L 12 , as shown in the front view in  FIG. 7( c ) . In this case, the mounting members  20  and  21  described above are also detached and are then used. The bracket securing holes HL 1 , HL 2 , HL 5 , and HL 8  are then used as the actual bracket securing holes, and the other bracket securing hole HS 2  and the like are not used. 
     Furthermore, in a case where the speaker bracket  1  is secured to the speaker hole BH of a fourth vehicle model, for example, the speaker bracket  1  is used as a speaker bracket  1 - 3  having its outer portion detached from each of the detaching grooves L 1 , L 2 , L 4 , L 5 , L 9 , L 11 , L 12 , and L 16 , as shown in the front view in  FIG. 7( d ) . In this case, the mounting members  20  and  21  described above are also detached and are then used. The bracket securing holes HL 1 , HL 2 , HL 5 , and HL 8  are then used as the actual bracket securing holes, and the other bracket securing hole HS 2  and the like are not used. 
     Also, in a case where the speaker bracket  1  is secured to the speaker hole BH of a fifth vehicle model, for example, the speaker bracket  1  is used as a speaker bracket  1 - 4  having its outer portion detached from each of the detaching grooves L 2 , L 4 , L 6 , L 8 , L 10 , L 13 , and L 15 , as shown in the front view in  FIG. 7( e ) . In this case, the mounting members  20  and  21  described above are also detached and are then used. The bracket securing holes HL 1 , HL 3 , and HS 7  are then used as the actual bracket securing holes, and the other bracket securing hole HS 2  and the like are not used. 
     Lastly, in a case where the speaker bracket  1  is secured to the speaker hole BH of a sixth vehicle model, for example, the speaker bracket  1  is used as a speaker bracket  1 - 5  having its outer portion detached from each of the detaching grooves L 2 , L 4 , L 6 , L 9 , L 10 , L 12 , and L 15 , as shown in the front view in  FIG. 7( f ) . In this case, the mounting members  20  and  21  described above are also detached and are then used. The bracket securing holes HS 8 , HS 3 , and HS 5  are then used as the actual bracket securing holes, and the other bracket securing hole HL 1  and the like are not used. 
     Note that, although the above detaching grooves L 1  to L 16  have been described as linear grooves with reference to  FIGS. 2, 4, and 7 , these detaching grooves may be curved detaching grooves. 
     As described above, in the configuration of the speaker bracket  1  of the example, the plurality of detaching grooves  201  and  202  having different extending directions is continuously formed on the base portion B of the mounting member  20  to be used for attaching the speaker SP to the speaker hole BH. Thus, it is possible to both maintain the strength for attaching the speaker SP to the lining BD with the mounting member  20 , and increase the workability in detaching the mounting member when the speaker SP is attached to the lining BD without the mounting member  20 . 
     Further, as the detaching groove  201  and  202  are a plurality of linear grooves connected at one bend point IP, the detaching grooves  201  and  202  can be formed by a simple process, while the strength is maintained, and the workability is increased. 
     Furthermore, the overall shape (see  FIG. 5 ) of the detaching grooves  201  and  202  viewed from a direction perpendicular to the extending direction of each of the detaching grooves  201  and  202  is a shape in conformity with the shape of the speaker hole BH to which the speaker SP is attached via the speaker bracket  1  after detachment of the mounting member  20 . Thus, it is possible to mount the speaker SP in the required region without fail, using the speaker bracket  1  after the mounting member  20  is detached. 
     Also, the detaching grooves  201  and  202  are formed only on one surface (which is the surface on the back surface side) of the plate-like base portion B (see  FIGS. 5 and 6 ). Thus, it is possible to maintain sufficient strength when the speaker SP is attached to an external portion with the mounting member  20 . 
     MODIFICATIONS 
     Next, modifications corresponding to the embodiment are described, with reference to  FIGS. 8 and 9 . Note that  FIGS. 8 and 9  are enlarged back views showing the configurations of mounting members of the respective modifications. Also, in  FIGS. 8 and 9 , the same components as the mounting member  20  and the support portion  10  of the example are denoted by the same reference numerals, and detailed explanation thereof will not be repeated. 
     (I) First Modification 
     First, the configuration of a mounting member of a first modification is described, with reference to  FIG. 8( a ) . As shown in its enlarged back view in  FIG. 8( a ) , in a mounting member  20 - 1  of the first modification, a detaching groove continuously formed in the same detaching groove  202  as that of the example via a bend portion IP is not a linear groove but a curved detaching groove  210  that protrudes toward the mounting member  20 . This detaching groove  210  corresponds to another example of the groove  201  of the embodiment. The other aspects of the configuration of the mounting member  20 - 1  of the first modification are the same as those of the configuration of the mounting member  20  of the example, and therefore, detailed explanation thereof is not made herein. In the configuration of the mounting member  20 - 1  of the first modification, the portion around the center of the detaching groove  210  protrudes downward in a vertical direction (see the usage mode shown in  FIG. 7( a ) ) at the time of installment of the speaker SP with the mounting members  20  and  21 . As a result, in a case where rain enters the back side of the speaker SP after the installation, for example, even if moisture due to the rain enters from the right side of the detaching groove  210  in  FIG. 8( a ) , the moisture can be stored in the protruding portion. Thus, it is possible to prevent the moisture from dripping down (which will result in leaking of rain). Note that, in the curved detaching groove  210  and the like of the first to fourth modifications, the tangential direction of the curve is the extending direction of the detaching groove  210  and the like. 
     (II) Second Modification 
     Next, the configuration of a mounting member of a second modification is described, with reference to  FIG. 8( b ) . As shown in its enlarged back view in  FIG. 8( b ) , in a mounting member  20 - 2  of the second modification, the same curved detaching groove  210  as that of the first modification, and a curved detaching groove  211  that protrudes toward the mounting member  20  like the detaching groove  210  are continuously formed in the base portion B via a bend portion IP. This detaching groove  211  corresponds to another example of the groove  202  of the embodiment. The other aspects of the configuration of the mounting member  20 - 2  of the second modification are the same as those of the configuration of the mounting member  20 - 1  of the first modification, and therefore, detailed explanation thereof is not made herein. Note that the detaching groove  210  of the mounting member  20 - 2  of the second modification also has the effect to prevent rain leakage like the detaching groove  210  of the above first modification. 
     (III) Third Modification 
     Next, the configuration of a mounting member of a third modification is described, with reference to  FIG. 9( a ) . As shown in its enlarged back view in  FIG. 9( a ) , a mounting member  20 - 3  of the third modification does not have the bend portion IP by which the detaching grooves  201  and  202  of the example are connected, but has only a curved detaching groove  212  formed therein. This detaching groove  212  corresponds to yet another example of the groove  201  of the embodiment, and yet another example of the groove  202  of the embodiment. The other aspects of the configuration of the mounting member  20 - 3  of the third modification are the same as those of the configuration of the mounting member  20  of the example, and therefore, detailed explanation thereof is not made herein. 
     (IV) Fourth Modification 
     Lastly, the configuration of a mounting member of a fourth modification is described, with reference to  FIG. 9( b ) . As shown in its enlarged back view in  FIG. 9( b ) , a mounting member  20 - 4  of the fourth modification does not have the bend portion IP like the mounting member  20 - 3  of the third example, but has only a curved detaching groove  213  having a different shape from that of the detaching groove  212  of the third modification. This detaching groove  213  corresponds to still another example of the groove  201  of the embodiment, and still another example of the groove  202  of the embodiment. The other aspects of the configuration of the mounting member  20 - 4  of the fourth modification are the same as those of the configuration of the mounting member  20  of the example, and therefore, detailed explanation thereof is not made herein. 
     As described so far, in the configuration of the mounting member  20 - 1  or the like of each modification, the detaching groove  210  or the like includes a curved groove. Thus, the detaching groove  210  or the like can be formed by a simple process, while the strength is maintained, and the workability is increased. 
     Also, in the configurations of the mounting member  20 - 2  of the second modification, the mounting member  20 - 3  of the third modification, and the mounting member  20 - 4  of the fourth modification, the entire detaching grooves  210  to  213  are formed as entirely curved grooves. Thus, the detaching grooves can be formed by a simple process, while the strength is maintained, and the workability is increased. 
     Note that, in the example, the first modification, and the second modification described above, the bend portion IP is formed only at one point. However, a detaching groove may be formed with a linear or curved groove in which a plurality of bend points is formed. Also, a cross-section of the detaching groove  201  or the like described above is substantially a V-shaped cross-section. However, the detaching groove  201  or the like may be formed with a groove having a rectangular cross-section with a bottom surface in its extending direction, a groove having a semicircular cross-section, or a groove having a U-shaped cross-section. 
     Further, in the cases described above in the example and the respective modifications, the detaching groove  201  or the like is formed on the back surface side of the base portion B of the mounting member  20 . However, the detaching groove  201  or the like may be formed on the surface on the front surface side of the base portion B, the support portion  10 , or the mounting members  20  and  21 . 
     Further, in the cases described above in the example and the respective modifications, the present application is applied to the speaker bracket  1  that is interposed between the speaker SP and the lining BD, and secures the speaker SP to the lining BD. However, the configuration itself of the speaker frame that is in the form of a frame and supports the diaphragm of the speaker to be attached to the lining BD, or the outer circumferential edge itself of the speaker may be the same as the configuration of the speaker bracket  1  that includes the mounting members  20  and  21  of the example, or the mounting member  20 - 1  or the like of each of the modification described above. In this case, the same effects as those of the example described above or each of the modifications described above can be achieved. 
     Furthermore, in the cases described above in the example and the respective modifications, the back surface of the circumferential portion of the support portion  10  is flat (see  FIG. 3 ). However, a lightening portion for weight reduction may be formed at a position other than the positions of the bracket securing hole HS 1  and the like on the back surface of the circumferential portion. 
     Also, in the example and the respective modifications described above, the entire speaker bracket  1  is formed by integral molding using a resin. However, part of the speaker bracket  1  may be made of a different material.
