1. A loudspeaker to be attached to an attachment member, the loudspeaker comprising:
a temporary joint pin which is provided on a rear end surface of a frame of the loudspeaker and is inserted into a temporary joint hole provided in the attachment member and temporarily holds the loudspeaker in a suspended state,
wherein the temporary joint pin includes:
a rod-like portion projecting from the rear end surface of the frame of the loudspeaker, the rod-like portion including a tilted surface on a circumferential surface thereof; and
a conical portion that is provided at a distal end of the rod-like portion and is tapered in a direction of projection of the rod-like portion, the conical portion including a bottom surface at the distal end of the rod-like portion and a notch on a tapered circumferential surface of the conical portion,
the tilted surface is to be brought into contact with an inner circumferential surface of the temporary joint hole, and is tilted to become closer to a central axis of the rod-like portion from a base end of the rod-like portion toward the distal end of the rod-like portion in the direction of projection such that a cross-sectional area of the rod-like portion is reduced from the base end to the distal end,
the bottom surface of the conical portion includes a flanged portion which protrudes in a direction crossing the direction of projection, and catches onto a rear surface of the attachment member,
the tilted surface of the rod-like portion continues to a bottom face of the notch of the conical portion at the distal end of the rod-like portion,
an area of the bottom surface of the conical portion is larger than the cross-sectional area of the rod-like portion at the base end, and
an inclination of the tilted surface of the rod-like portion is smaller than an inclination of the tapered circumferential surface of the conical portion.
