目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an amplifier for an electrostatic speaker. Conventionally, it is difficult to obtain a high output voltage using transistors. The purpose of this invention is to obtain a method that eliminates this point.
この発明を図面に基づいて説明すると次のとおりである
。The present invention will be explained as follows based on the drawings.

イアスを付加した島台である。FIG. 1 shows the voltages during operation of fixed poles A1, imaging plate B1, and fixed poles C of an electrostatic speaker. Figure 82 shows a barrel c.
In other words, it is an island platform with an AC bias of the same period.

ランスのＩＩ！！影―をうけない。B becomes the one that has undergone the AM modification. In terms of low frequencies, Figures 2 and 3 behave similarly to Figure 1. This invention is a method of making the output of the amplifier as shown in Figures 42-3. As a result, the impedance of the load becomes constant, a step-up transformer can be used for the output, and the I&W property can be maintained regarding the amplitude by the NFB in the aI circumference m region. In other words, in terms of low frequency, it is a transformer II! ! Not affected by shadows.
この発明は以上説明したように、出力を＾周彼変曙する
