| 主权项 | 1. A transducer comprising:— a. a vibrator body for generating and/or receiving acoustic or ultrasonic waves having:— i. a first anti-resonance frequency, andii. a second anti-resonance frequency, b. a matching layer having a substantially single acoustic impedance, the matching layer coupled to said vibrator body so as, in use, to acoustically match the vibrator body to a medium,wherein said first anti-resonance frequency is substantially an odd multiple of said second anti-resonance frequency. | ||
