A speaker (110) including: a chassis (111) internally including a magnet (11); a plate (12) attached to a top face of the magnet (11); a voice coil (15) disposed in a magnetic air gap (14) formed in an outer perimeter of the plate (12) so as to be vibratable in a vertical direction; a diaphragm (16) having a periphery (16b) that is connected to an upper end of the voice coil (15); and a suspension (17) connecting the diaphragm (16) and the chassis (111). The suspension (17) includes a first fixing part (21) fixed to the diaphragm (16) and a second fixing part (22) fixed to the chassis (111). The second fixing part (22) is positioned above the first fixing part (21), and at least one of the first fixing part (21) and the second fixing part (22) is disposed in an inner region (D1) which is a region located inward of the periphery (16b) of the diaphragm (16) as seen from above.
