Ultrasonic radiation apparatus and hair care apparatus

An ultrasonic radiation apparatus comprising:

• a first transducer support with a substantially planar first main face, having a plurality of first mounts on the first main face;
• a second transducer support with a substantially planar second main face, having a plurality of second mounts on the second main face;
• a plurality of first ultrasonic transducers attached to the plurality of first mounts to radiate ultrasonic waves traveling along a first direction;
• and
• a plurality of second ultrasonic transducers attached to the plurality of second mounts to radiate ultrasonic waves traveling along a second direction different from the first direction, and wherein
• the first transducer support, the plurality of first ultrasonic transducers, the second transducer support, and the plurality of second ultrasonic transducers are arranged such that a first focal point at which ultrasonic waves radiated by the plurality of first ultrasonic transducers converge coincides with a second focal point at which ultrasonic waves radiated by the plurality of second ultrasonic transducers converge.

A hair care apparatus comprising:

• a plurality of side supports;
• a plurality of first ultrasonic transducers attached to each of the plurality of side supports;
• a bottom support;
• a plurality of second ultrasonic transducers attached to the bottom support;
• and
• a controller that substantially simultaneously drives the plurality of first ultrasonic transducers and the plurality of second ultrasonic transducers, and wherein
• each of the plurality of side supports has a main face,
• the bottom support has a main face,
• the bottom support and the plurality of side supports are arranged so that the main face of the bottom support and the main faces of the plurality of side supports are non-parallel to each other,
• the plurality of side supports are arranged so that normals extending from the main faces of the plurality of side supports toward the direction of ultrasonic radiation by the plurality of first ultrasonic transducers does not intersect the main face of the bottom support, and
• the plurality of side supports, the plurality of first ultrasonic transducers, the bottom support, and the plurality of second ultrasonic transducers are arranged such that a first focal point at which ultrasonic waves radiated by the plurality of first ultrasonic transducers converge coincides with a second focal point at which ultrasonic waves radiated by the plurality of second ultrasonic transducers converge.
