DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a directional
microphone, and its purpose is to be both enjoyable and directional. We have enough to provide
the I of I Ikrophone. . The main vibration shakes the film of the piezoelectric effect itself with 111
+ Ii. Then make two terminals, one on the IE side and the other on the fjAIIll board. I will look at
the sound waves that are in phase with each other 1. The microphone has a directional
characteristic of 鳳-finger-15 and has few parts. It belongs to Rojo 3 /. In the following, when the
sound is generated according to an embodiment of the present invention shown in FIG. 1, 1 is a
film-like piezoelectric element, which is a horizontal movement, a rough case, 2 a mounting
league. I ': I :: rz, 5-, 7. 4.1 ++ 18 and so on + -1 and the above-mentioned fine root 1 is pinched
after attaching its 1M 4 to the mounting 2 And case & K? Will be attached. . 6 in the book air
layer for 甑 甑 細 1 fibrillation. In order to form this layer, it is a hole for a sound I child provided
substantially at the center of the upper part 3 ·, i −, which is a hot-dip soak in the case 3 to form
this layer. In this sound 4 material, the 'A stream E that penetrates the X hole 4 is converted to
the sound material porous material IIII' r 'phase change, and the + h energy 1 person 1 is
Resistance t is controlled. a is an air chamber of low-pitched air i r − air room, and a soundrecording material 5 is made into a woman's hole 4 in this Kamakura hole 4 because it is 1/1 °
□, so it is a contemporary condenser microphone. Compared with F1 etc., there are few parts
and it is easy to manufacture and relieve. Two points and four suns, the eternity point that
