Abstract
An electroacoustic transducer comprises an electric sound conversion section that vibrates a mechanical device based on an electric signal so as to emit a sound wave; and an electromagnetic wave radiation section that generates and emits an electromagnetic wave from the electrical signal.
Claims20
An electroacoustic transducer comprising:
- an electric sound conversion section that vibrates a mechanical device based on an electric signal so as to emit a sound wave;
- and
- an electromagnetic wave radiation section that generates and emits an electromagnetic wave from the electrical signal,
- wherein the electromagnetic wave radiation section is arranged so that a radiation direction of the electromagnetic wave and a direction of movement of the sound wave is in agreement.
