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.
