utility model Tofog-such as sound 1a1111 incident on the Ili surface of the Zuirum-like
diaphragm cast having the four rudder piezoelectric effect of seeking 14 terminal 605 In order to
make human impedance variable, this end. Now you can adjust the porous material 9 to the child.
A variable directional microphone Rohon characterized by facing each other. The present
invention relates to a variable directional microphone. ?, if it is 0, then ? is directional in% 111

frequency band. ?? I will hold it. There is a sound pressure cover of cover 10 in one cast. The
spacer ring 2 has a base 6 attached to it, and an air chamber 4 for sound pressure @ monk and
an air chamber 5 for bass compensation are provided by the nose 3 and the defibrillation plate 1.
6 is a sound pressure port on the rear side of the back of the fi moving plate for giving sound
waves (one end-? -) This sound one terminal 6 is opened and closed by the plate 8 and the
porous material 9) 7 like lipo-t! According to the 10th, input sound-to change the impedance and
twin. There is no such thing as K that can be changed from directivity to omnidirectional.
Reference numeral 12 is a cushion, and the external material 8 "is used for the b" c э) theta

case 1a so as not to cause an electrical wax defect. In the present invention, two sound terminals
are made on the # surface of the excitation plate, and the sound pressure which is the phase
