| titleOfInvention | Ultrasonic transducer |
| abstract | The efficiency of an ultrasonic transducer is influenced by acoustic matching means, but in order to improve the characteristics, it is necessary to use a light and slow sound speed material for the acoustic matching means. However, there exists a subject that intensity | strength will fall when lightening. In order to solve the above problems, the present invention comprises an acoustic matching means 21 made of a plurality of different materials, and at least one of the materials forming the acoustic matching means 21 is vibration caused by a temperature change. The structure is configured to relieve stress on other materials caused by the difference in expansion and contraction between the means 16 and the acoustic matching means 21. [Selection] Figure 1 |
