  • Acoustic matching layer
    Patent number: 11468876
    Abstract: An acoustic matching layer includes a base material having a plate-shaped member made of a metal, a ceramic, or glass. Depressed portions are partially provided in a vibration surface of the base material toward a joining surface of the base material that is in a propagation direction of a sound wave.
    Type: Grant
    Filed: June 21, 2018
    Date of Patent: October 11, 2022
    Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.

  • Multilayer body that includes piezoelectric body
    Patent number: 11162829
    Abstract: A multilayer body includes a piezoelectric body and a first acoustic matching layer in direct or indirect contact with the piezoelectric body. The first acoustic matching layer includes a plastic foam containing a plurality of closed pores. An average pore size of the closed pores is not smaller than 1 ?m and not larger than 100 ?m. The first acoustic matching layer has a density of not less than 10 kg/m3 and not more than 100 kg/m3.

  • ACOUSTIC MATCHING LAYER
    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.
