Piezoelectric electro-acoustic converter
专利汇可以提供Piezoelectric electro-acoustic converter专利检索，专利查询，专利分析的服务。并且PURPOSE:To increase the power caused through the field function by combining the vibration films of more than two units of the electro-acoustic converter into one vibration system. CONSTITUTION:Vibration film 1 made of the companding piezoelectric film having the evaporation electrode on the surface forms the concave surface to the outside and is then stretched being held between stators 4a and 4b. The space formed by film 1 is sealed up. The space can also be filled with the gas or the light-weight small substance. In such way, films 1 of the two converters are combined into on vibration system, and electrode terminals 3a and 3b are distributed so that the centers of gravity of the both vibration films may move in the same direction via the same signal voltage. As a result, the power caused by the field can be increased to increase the overall capacity, thus decreasing the winding ratio of the boosting transformer.，下面是Piezoelectric electro-acoustic converter专利的具体信息内容。
