A loudspeaker includes a frame coupled to a magnetic circuit, a cone diaphragm coupled to an outer periphery of the frame, a voice coil coupled to the cone diaphragm, the voice coil having a portion placed in a magnetic gap of the magnetic circuit, a tubular port having an end coupled to the voice coil, and a diameter of another end of the tubular port is larger than a diameter of a connecting portion at which the end of the tubular port is coupled to the voice coil, and a dome covering an upper end of the tubular port. A center axis of the tubular port inclines at least by 5° with respect to a center axis of the voice coil.
