Abstract
An improved compact electroacoustic transducer and loudspeaker system. The electroacoustic transducer (or array of electroacoustic transducers) can generate a desired sound by the use of pressurized airflow. The electroacoustic transducer does not have frames (unlike prior electroacoustic transducers) and an electrically conductive membrane is now supported by a pair of non-conductive vent members.
