| 摘要 |
<p>The invention relates to a transducer plate for electro-acoustic transducers, such as used in telecommunications technology, having a carrier plate and a ceramic plate arranged on a carrier plate. The invention teaches a transducer plate which is dimensioned so that it can be used in a microphone, a receiver or a piezoelectric VF ringing device despite the different voltage response factors required for each application. The following dimensions should preferably be used: transducer plate diameter (02)=43 mm; ceramic plate diameter (01)=30 mm; transducer plate thickness (d)=150 microns; and ceramic plate thickness (1)=90 microns.</p> |
