扭转换能器的性能测试

Measurement of performance parameters of torsional vibration transducers

提出一种通过对称式扭转换能器结构获得理想声场及测量扭转换能器电声效率的新方法．用该方法和导纳圆法对扭转振子的电声效率进行了测量．实验表明，两种测试方法所得结果吻合较好．

By designing a construction of torsional vibrator, a new way of measuring electro -sound effect has been put forward and it is compared with the way of measuring admittance circle.Both results are nearly the same.
