摘要：An electro-acoustic transducer includes a needle electrode, an oppositeelectrode, a discharge region between the needle electrode and the opposite electrode,a high-frequency oscillating circuit in the discharge region causing a high-frequencydischarge and modulating and extracting an audio signal in accordance with a sound wave

introduced to the discharge region, or converting the discharge in the discharge regioninto a sound wave, the discharge being performed in accordance with a high-frequencysignal modulated by an audio signal, and an inert gas supply channel that supplies inertgas toward the peripheral surface of the needle electrode. The electro-acoustictransducer includes a needle-electrode cover as a part of the inert gas supply channel.The needle-electrode cover extends beyond the tip of the needle electrode toward theopposite electrode and has a gas flow outlet disposed beyond the tip of the needleelectrode toward the opposite electrode.
