  "abstract": "A speaker includes a flange portion, a locking member and a connecting portion. The flange portion includes a penetration hole. The locking member is arranged in the penetration hole and includes a locking portion that protrudes from the flange portion and is to be locked in a mounting hole in a prescribed size. The connecting portion connects an end surface facing the penetration hole with the locking member and is to be cut by a hand tool.",
  "claims": [
    "1. A mounting structure having a flange portion which includes a first penetration hole, on a mounted member which includes a second penetration hole, the mounting structure comprising: the engaging member including: a first engaging portion which is inserted into the first penetration hole to be engaged with the flange portion; a first axial portion having the first engaging portion; a second engaging portion which is inserted into the second penetration hole to be engaged with the mounted member; a second axial portion having the second engaging portion and having the same axial line as the first axial portion or a parallel axial line to an axial line of the first axial portion; a guard portion formed to connect the first axial portion with the second axial portion and to extend in a direction orthogonal to the axial line of the first axial portion and the axial line of the second axial portion; and a flexible portion having an engaging portion in stairs and is elastically deformable inward in a diameter direction, wherein the flexible portion is to be engaged in the first penetration hole or the second penetration hole, and wherein while the flange portion is sandwiched between the first engaging portion and the guard portion by engaging the first engaging portion with the flange portion, the speaker is mounted on the mounted member by means of the engaging member by engaging the mounted member with the second engaging portion.",
    "2. A mounting structure having a flange portion which includes a first penetration hole, on a mounted member which includes a second penetration hole, the mounting structure comprising: an engaging member including: a first engaging portion which is inserted into the first penetration hole to be engaged with the flange portion; a first axial portion having the first engaging portion; a second engaging portion which is inserted into the second penetration hole to be engaged with the mounted member; a second axial portion having the second engaging portion and having the same axial line as the first axial portion or a parallel axial line to an axial line of the first axial portion; and a guard portion formed to connect the first axial portion with the second axial portion and to extend in a direction orthogonal to the axial line of the first axial portion and the axial line of the second axial portion; wherein while the flange portion is sandwiched between the first engaging portion and the guard portion by engaging the first engaging portion with the flange portion, the speaker is mounted on the mounted member by means of the engaging member by engaging the mounted member with the second engaging portion, wherein the first penetration hole includes an expanding hole communicated with the first penetration hole to extend outward in a diameter direction, wherein the first axial portion includes a base portion to be passed through the first penetration hole, and a claw portion formed on the base portion to protrude outward in the diameter direction and to be passed through the expanding hole, wherein the claw portion is formed to sandwich the flange portion between the claw portion and the guard portion by rotating the first axial portion after the claw portion is passed through the expanding hole, wherein the second axial portion includes a flexible portion that has an engaging portion in stairs and is elastically deformable inward in a diameter direction, and wherein the flexible portion is to be engaged in the second penetration hole.",
    "3. A mounting structure having a flange portion which includes a first penetration hole, on a mounted member which includes a second penetration hole, the mounting structure comprising: an engaging member including: a first engaging portion which is inserted into the first penetration hole to be engaged with the flange portion; a first axial portion having the first engaging portion; a second engaging portion which is inserted into the second penetration hole to be engaged with the mounted member; a second axial portion having the second engaging portion and having the same axial line as the first axial portion or a parallel axial line to an axial line of the first axial portion; and a guard portion formed to connect the first axial portion with the second axial portion and to extend in a direction orthogonal to the axial line of the first axial portion and the axial line of the second axial portion; wherein while the flange portion is sandwiched between the first engaging portion and the guard portion by engaging the first engaging portion with the flange portion, the speaker is mounted on the mounted member by means of the engaging member by engaging the mounted member with the second engaging portion, wherein the first penetration hole includes: a first sub penetration hole formed at a first position on the flange portion and having a first inside diameter; a second sub penetration hole formed at a second position separated from the first position in a circumferential direction and having a second inside diameter smaller than the first inside diameter; and a connecting hole communicating the first sub penetration hole with the second penetration hole and having a width smaller than the second inside diameter, wherein the first axial portion includes: a base portion connected to the guard portion, having an outer diameter smaller than the second inside diameter and to be passed through the connecting hole; and a flange formed on an end of the base portion and having an outer diameter smaller than the first inside diameter and larger than the second inside diameter, wherein the flange of the first axial portion is formed to sandwich the flange portion between the flange and the guard portion by passing the flange through the first sub penetration hole and subsequently moving the base portion to the second position through the connecting hole, the second axial portion includes a flexible portion that has an engaging portion in stairs and is elastically deformable inward in a diameter direction, and wherein the flexible portion is to be engaged in the second penetration hole."

  "description_excerpt": "The present invention relates to a speaker and a speaker mounting structure.\n\nJapanese Patent No. 4603829 (Patent Literature 1) describes a structure for mounting a speaker on a plate-like mounted member.\n\nThe speaker mounting structure described in Patent Literature 1 interposes amounting tool made of a resin between the mounted member and a frame of the speaker. The mounting tool includes a locking portion on one end thereof, which is to be locked in a hole formed on the mounted member, and an engaging portion on the other end thereof, which is to be engaged with the frame of the speaker and has a screw hole formed thereon, into which a tapping screw is to be screwed.\n\nWhen the speaker is mounted on the mounted member, the engaging portion of the mounting tool is first engaged with the frame of the speaker, and the frame is fastened together to the screw hole of the engaging portion by the tapping screw. Then the locking portion of the mounting tool mounted on the speaker is locked in the hole of the mounted member. In this way, the speaker is mounted on the mounted member by means of the mounting tool.\n\nThe speaker mounting structure described in Patent Literature 1 needs the mounting tool as a dedicated part for mounting the speaker, in addition to the tapping screw. Accordingly, there is room for improvement in decreasing the number of parts. Moreover, as the tapping screw is made of a metal to secure the intensity, there is room for improvement in reducing the weight. In particular, the improvement is greatly desired in onboard use.",
