Abstract: A loudspeaker unit includes a frame, a diaphragm having an inner periphery and an outer periphery, and a magnetic circuit coupled to the frame. The frame includes a first support part, a second support part, a pedestal part, and a plurality of reinforcement parts. The first support part supports the outer periphery of the diaphragm, and the second support part supports the magnetic circuit. The pedestal part spreads outward from the outer periphery of the first support part. The plurality of reinforcement parts are disposed side by side along the periphery of the pedestal part and fixed to the outer periphery of the first support part and the pedestal part. Each of the plurality of reinforcement parts includes a first portion having a first height relative to the pedestal part, and a second portion having a second height lower than the first height.

Abstract: A loudspeaker unit includes a frame that supports a diaphragm and a magnetic circuit. The frame includes: a first support supporting a perimeter of the diaphragm; a pedestal extending outwardly from a perimeter of the first support; fastening portions provided in positions on the pedestal that surround the perimeter of the first support; and reinforcements disposed in regions of the pedestal between the fastening portions, and fixed to the first support and the pedestal. The reinforcements include: a first plate portion that is a plate-shaped portion disposed in front of the pedestal to face the pedestal, and has a bent shape that protrudes in the forward direction; and a second plate portion that is a plate-shaped portion disposed in front of the pedestal to face the pedestal and the first plate portion, and has a bent shape that protrudes in a rearward direction.
