Title: Ultrasonic probe
Inventor: ISHIKAWA HIROSHI
IPC: H04R17/00
Filed: 1992-12-21
Abstract: PURPOSE:To improve the beam shape by changing the product of the potential applied to a piezoelectric vibrator and the electrode area in the preset direction. CONSTITUTION:A piezoelectric vibrator 1 is divided into five in the short-axis direction and the arrangement direction respectively into a lattice shape. A resistor 11 is stuck on the back face of the piezoelectric vibrator 1. The resistance value of the resistor 11 is changed in steps in the short-axis direction. When voltage is applied across a front electrode 1a and a back electrode 1b, the potential changed in steps in the short-axis direction is applied to the piezoelectric vibrator 1. Only the electrodes 1a of oblique line portions are used in the region having the depth of 50mm or below in a testee, and the electrodes 1a of both the oblique line portions and net line portions are used in the deeper region. The product of the potential and the electrode area is made large at the center in the short-axis direction and made smaller toward the end, and the beam shape in the short-axis direction is sharply improved as compared with the conventional one. The shape of the product is changed on the near side and the far side in the testee in particular, thereby the beam shape is further improved.
