摘要：Provided is an ultrasonic transducer including: a housing including a bottomsurface and side members, the side members facing each other and extending upwardlywith a space part therebetween, the housing having an opened upper part; a piezoelectric
resonator disposed at an upper portion of the bottom surface; a housing auxiliarymember disposed at upper portions of the side members and inserted into the spacepart; and a signal connection pin part disposed at an upper portion of the housingauxiliary member. In particular, the housing auxiliary member is formed of material havinga lower density than the housing, thereby improving isotropic radiation characteristics.Sides of the housing are symmetrically opened by a structure for the ultrasonictransducer so that an isotropic radiation angle of ultrasonic waves is maximized toimprove accuracy of sensing an obstacle, an internal structure of the housing is simplifiedin such a way that no additional process is required, thereby reducing manufacturing cost,and the housing auxiliary member is combined with the opened part of the housing sothat external pollution can be prevented from entering into the ultrasonic transducer.
