BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional
microphone, and FIG. 2 is a cross-sectional view of the microphone to which the present
invention is applied. 1 is a microphone case, 3 is a diaphragm, 5 is an acoustic hole, 8 is an
equalizer, and 9 is a microphone cap. Fig. 1 Fig. 2 7385-67-
DETAILED DESCRIPTION OF THE INVENTION This invention is a book related to the
improvement of the mounting structure of the equalizer located in front of the diaphragm of the
microphone unit. In the dynamic microphone VC, the i [11] k equalizer of the diaphragm 3
attached to the microphone unit 2 attached to the front of the microphone case l as shown in FIG.
4 is attached. This equalizer 4 # 'i is formed by molding a metal plate or plastic, etc., and several
acoustic holes 5 are provided, and the relationship between the diaphragm 3 and the equalizer 4
(I) AO-001Qn-n') The frequency characteristic is corrected by the space and the acoustic hole 5.
However, the conventional equalizer 4 is separate from the microphone cap 6 attached to the
front of the microphone case 1, and the equalizer 4 is attached to the front of the microphone
case l with the protective network 7 and the microphone cap 6 . In this device, the abovementioned equalizer 4 is integrated with the microphone cap 6 to make a part point #! As shown
in FIG. 2, the equalizer 8 having the acoustic hole 5 is integrally formed with the microphone cap
9, and the protective net 7 is attached to the front of the cap 9 to make the camp 9 a microphone
case. If attached to the front part of 1, the equalizer 8 is located in direct # of the diaphragm 3 of
the microphone unit 2, and the space between the moving plate 3 and the equalizer 8 and the
acoustic hole 5 and K for frequency characteristics It can be corrected. In this invention, as
described above, since the equalizer 8 is integrally formed with the 2148-99i30-03 microphone
cap 9, the number of parts All is reduced, and the assembling operation of the microphone
becomes inconvenient.
