ABSTRACT:
The invention provides a miniaturized and low-profile electroacoustic transducer. In the electroacoustic transducer, a space is formed underneath a magnet by diminishing a vertical thickness of the magnet in comparison with the height of a magnetic core, and also by disposing the magnet at a position trensversely aligned to an upper portion of the magnetic core, so that the space is utilized as a part of a back space at the back of a diaphragm, and for connection of terminals of a coil with external terminals, thereby realizing miniaturization and flattening in the shape of the electroacoustic transducer.
