An edge has an inner circumferential portion connected to an outer circumferential portion of a diaphragm, and is made of an annular elastic deformation member. A frame is connected to an outer circumferential portion of the edge, and supports the diaphragm through the edge. A magnetic circuit displaces the diaphragm in a first direction that is a sound emission direction and in a second direction that is an opposite direction to the sound emission direction, and vibrates the diaphragm. In a region between the inner circumferential portion and outer circumferential portion of the edge, the edge includes a rib, which is protruded in the second direction, and limits a stroke of the diaphragm in the second direction. |

1. A speaker comprising:
a diaphragm; an edge, which has an inner circumferential portion connected to an outer circumferential portion of the diaphragm, and is made of an annular elastic deformation member; a frame, which is connected to an outer circumferential portion of the edge, and supports the diaphragm through the edge; a magnetic circuit, which displaces the diaphragm in a first direction that is a sound emission direction and in a second direction that is an opposite direction to the sound emission direction, and vibrates the diaphragm, and at least one rib, which is protruded in the second direction, and limits a stroke of the diaphragm in the second direction, the rib being provided in a region between the inner circumferential portion and outer circumferential portion of the edge. |
