Abstract
An electroacoustic transducer includes: a diaphragm having two pairs of longitudinal split tubular surfaces; a converter that performs conversion between vibration of the diaphragm and an electric signal; and a supporter supporting the diaphragm. The two pairs of longitudinal split tubular surfaces form valleys and ridge portions. In each pair of the two pairs of longitudinal split tubular surfaces, one-side portions of the respective longitudinal split tubular surfaces form a valley. Another-side portion of the split tubular surface of each one of the two pairs and an other-side portion of the split tubular surface of the other of the two pairs form a ridge portion. The two pairs of longitudinal split tubular surfaces are arranged in at least one of a state in which the valleys are orthogonal to each other and a state in which the ridge portions are orthogonal to each other.
