H7,as、 h ′″″I j[II&L kK*fi、7″′″m60′。 The piezoelectric transducer of the 91 · 1 lure 6.00 has a complicated structure, is unreliable, and has an effective frequency band. The present invention wFi is an improvement of the disadvantages of such a conventional electric transducer, in which a trapezoidal resin vibrator is adhered and provided at the center of a square plate bimorph, so that the number of fFl An object of the present invention is to provide a t-piezoelectric transducer having a wide band, a simple structure, a high reliability, and an excellent transmission / reception sensitivity. The following is an example of this invention according to the Yr drawing. In FIG. 2 (in the case of the l holding stand, the basic base 1a is provided with the bimorph # 1 lb and the terminal bin 10). 2 is a square hole type bimorph, and one lead * 42a is provided from both sides. It is a three-in-asquare-shaped rooster-shaped oscillating body. 4 is Meshus, 5 is a rumor case, and 6 # 'i shields. As shown in FIG. 3, the parts are assembled as shown in FIG. That is, the shield plate 6 is placed on the holding table 10 only, and the holding plate 10 is placed on the a nozzle 1b of the holding plate 1), Place the square plate bimorph 2 and connect the lead # IJ2a to the wheeze chip pin IC respectively. Glue on the center of square plate bimorph 2. Take a picture 3) Then, the holding case 1 and the shield plate 6 are fixed to 11 as the holding case 1 in which the mesh 4 is scolded. 04-05-2019 1 In addition to the shape t + t4 of the resin pregnancy caster and the square pyramidal frustum shape of the pit 2, as shown in the brush 41 sentence, a round table, a table on a circle, a bowllike table, a sphere, a hemisphere Things etc. are considered. The present practice shown in the second and 31st chapters (1 wave of 91, feature (2) is a book as shown in the fifth). As described above, according to the present invention, since the trapezoidal tree-like vibration body is attached to the central part of the square plate bimorph, the frequency 'Ik band is wide, and the structure is simplified and the reliability is improved. Itching, and the beading 1'V temperature is excellent. 04-05-2019 2
