A speaker capable of suppressing deterioration of acoustic efficiency while allowing miniaturization of the speaker includes a first unit (20) and a second unit (21) each of which outputs sound. The first unit (20) includes: a diaphragm (25) which vibrates back and forth to radiate sound; and plural suspensions (26a, 26b, 26c, 26d) which support, at different positions, an outer periphery of the diaphragm (25). At least one of air passages (35a, 35b) for channeling sound from the second unit (21) to the outside is provided between the plural suspensions (26a, 26b, 26c, 26d). |
