Abstract
An electroacoustic transducer includes a frame defining a hollow space, and an elastic member mounted on the frame. The elastic member includes a circular plane lamina and a plurality of elastic arms extending outwardly from a circumference of the circular plane lamina. A diaphragm includes a vibrating film mounted with the circular plane lamina, and an edge damper integrally formed with an outer periphery of the vibrating film. A voice coil is attached below the vibrating film and electrically connected to the circular plane lamina. At least two through holes are formed between an outer periphery of the circular plane lamina and an inner side of the voice coil for balancing the air pressure of the air below the diaphragm.
