ABSTRACT:
The present invention provides a small electroacoustic transducer which is improved in sound characteristic by enlarging and adjusting a volume of a resonance space. A second resonant chamber as an auxiliary space is formed relative to a first resonant chamber formed in front of a resonance plate, wherein the first and second resonant chambers are connected with each other to enlarge the volume of the resonant volume.
