摘要： A two-way communication device includes a magnetoelastic rod located between an inertial back mass and a front panel of low mass. A coil is located in the vicinity of the rod, and the rod and coil together define an audio-electric transducer. An electronic processing circuit ensures that an audio-electric signal input to the device is applied to the coil to produce a sound wave from the low mass front panel and that when a sound wave impinges on the low mass front panel an audio-electric signal is produced and output from the device.
