MICROPHONE TRANSDUCER |
摘要 |
A piezo-electric transducer element is disclosed which is formed by selected etchings from boron doped silicon. The transducer includes a diaphragm and a spring lever adapted to bias the transducer element into a state of strain so that a vibration of the diaphragm is transmitted to the transducer element. the transducer element is particularly suitable for use in a telephone microphone. |
