Abstract: An ultrasonic transducer utilizes a unique forward acoustic transmission line comprised of a composite structure partially consisting of a portion of a continuous smooth sheet of material, such as an automobile bumper, from which the acoustic beam is emitted. This makes it invisible to sight, thus allowing for an improved object detection system in which the sensors cannot be seen, so that they do not interfere with the smooth lines that were designed into the surface of the object or vehicle onto which they are mounted. This is a significant improvement for applications where the look and style of the surface of the platform is important, such as in automotive park assist systems.

Abstract: In an inner bottom surface of a case, a substantially oblong recess having a long axis and a short axis forms a vibration area. A piezoelectric element is bonded to the center of the recess. On the opposite sides of the vibration area, vibration suppression areas thicker than the vibration area are disposed. A side portion of the case is formed to be thin over the entire circumference thereof. A reinforcing member higher in rigidity than the case is bonded to upper portions of the vibration suppression areas. The reinforcing member has a bottom surface substantially equal to the shape of the vibration suppression areas, and has a predetermined height. A gap between the reinforcing member and an inner side surface of the case is also filled with a filling member.

Abstract: A vehicle warning apparatus may include a supersonic speaker for outputting a supersonic wave that is equipped in a parametric speaker. The supersonic speaker includes a supersonic vibrator that generates a supersonic wave. A waterproof sheet and louver is arranged to cover a speaker opening in order to protect the supersonic vibrator from water and other foreign particles. Specifically, the waterproof sheet is arranged to cover the speaker opening at a distance L1 from the supersonic vibrator, where L1=L0×n/4±1/4. The louver is disposed on the other side of the waterproof sheet, such that the waterproof sheet is between the louver and the supersonic vibrator. The distance between the louver and the waterproof sheet is L2, where L2=L0×n/4±1/4. For both L1 and L2, L0 is the wavelength of the supersonic wave, and n is an odd number.
