| 摘要 |
The invention concerns an electro-acoustical transducer with a transducer plate having a piezo electric layer and which subdivides the housing of the transducer into a front and back chamber. In the front chamber, means are provided for the attenuation of resonance increases comprising Helmholtz resonators and an attenuation disc. According to the invention, the Helmholtz resonators are designed in such a manner that their effective surface is not reduced in size by means of the attenuation disc or wafer. This is attained according to the invention in that slots are formed in a separating plate. |
