发明名称 Electroacoustic transducer having diaphragm with coil mounting projections and interposed stabilizing walls
摘要 An electroacoustic transducer (1) has a magnet system (7) and a moving coil (15), which is disposed in the air gap (14) of the magnet system (7), and a diaphragm (17) attached to the moving coil (15). The diaphragm (17) has a mounting zone (24) for mounting the moving coil (15), and projections (25) in the mounting zone (24). The diaphragm (17) also has an interspace between every two projections (25), and two stabilizing walls (32, 33), which are inclined with respect to the diaphragm axis (18), are arranged in each interspace and are arranged so as to form a roof shape and are formed so as to project beyond the mounting zone (24) in radial directions.
