  • Publication number: 20220228894
    Abstract: There are provided piezoelectric element, case having conductivity, first acoustic matching layer bonded on case, and second acoustic matching layer stacked on and bonded to first acoustic matching layer. A joining part between first acoustic matching layer and second acoustic matching layer is located inside an outer periphery of a joining surface of first acoustic matching layer that is joined to second acoustic matching layer. This configuration can prevent indirect wave generated in first acoustic matching layer from propagating to second acoustic matching layer, and can therefore reduce reverberation of an ultrasonic wave.

  • Publication number: 20200175957
    Abstract: As a base material, a plate-shaped member made of a metal, a ceramic, or the like is used, and dense portion provided in a propagation direction of the sound wave, and depressed portions are provided, the depressed portions being partially provided in vibration surface of the base material having a plate shape toward joining surface that is in a propagation direction of a sound wave. This configuration reduces an acoustic impedance, and allows transmission of the sound wave to a gas to be efficiently performed. Furthermore, since dense portion where the sound wave is propagated has a high density, an acoustic transmission loss is small, and excellent characteristics as an acoustic matching layer can be obtained.
