Electroacoustic transducer |
摘要 |
The invention relates to an electroacoustic transducer for telephone sets with [lacuna] arranged in a housing with at least one piezoceramic layer applied to a carrier and provided on both sides with electrodes. It is the object to modify the structure of such a transducer in such a manner that it is compatible with automatic machinery and can thus be inexpensively produced. This object is achieved by having a plastic foil (6) as carrier on which conductor tracks (7, 8) to the electrodes of the piezoceramics are arranged, conducted and contacted. Applicable in telephone engineering. <IMAGE>
