Abstract: The present disclosure relates to a temperature controllable anechoic sound absorber using two different kinds of scattering particles and a method for manufacturing the same. More specifically, a temperature rise controllable anechoic sound absorber using two different kinds of scattering particles, which absorbs a sound wave which is transmitted through a medium, includes a composite material which induces a scattering process of the sound wave and has a first scattering particle and a second scattering particle; and a base material which fills a base of the absorber during the scattering process of the sound wave. Herein, volume content ratios of the base material, the first scattering particle, and the second scattering particles are adjusted so that a heat capacity of the absorber is within a set heat capacity range.

Abstract: The present disclosure relates to an acoustic lens using a Fresnel zone plate, a design method and a manufacturing method of the acoustic lens, a focusing ultrasonic transducer to which the acoustic lens is applied, and a manufacturing method of the focusing ultrasonic transducer. More specifically, an acoustic lens using a Fresnel zone plate which is applied to a focusing ultrasonic transducer. The acoustic lens includes a plurality of concentric regions which is concentrically disposed with respect to a center point. In the concentric region, a sound insulation region which blocks an entering sound wave and a transmission region which transmits the sound wave are alternately formed in a radial direction from the center point, and the entering sound wave is focused near a focal point.

Abstract: The present invention relates to a flat-plate focusing ultrasonic transducer and an acoustic lens composed of an annular array piezoelectric element and methods of manufacturing and designing thereof, more particularly to a flat-plate focusing ultrasonic transducer composed of an annular array piezoelectric element, wherein the annular array piezoelectric element has a plurality of concentric regions which is concentrically arranged in a concentric circle shape with respect to a center point, the concentric region has ring shaped sound insulation regions and piezoelectric regions which are alternatively formed in a direction from the center point to a radius direction, so as to focus a sound wave near a focal point, wherein the piezoelectric regions are composed of a piezoelectric ring that is composed of a piezoelectric material and thus excites a sound wave, the concentric region is in a shape of a flat-plate of which both sides are flat and which has a constant thickness, and each radius of the plurality of the sound insulation regions and the piezoelectric regions in the concentric region are calculated based on a set focal length of the ultrasonic transducer and a frequency of a set sound wave.
