- the material of the outer sub-diaphragm 6b can be the same as the material of the inner sub-diaphragm 6a, and may be a material that is slightly softer than that.
- the inner sub diaphragm 6a and the outer sub diaphragm 6b can be integrally formed, or the inner sub diaphragm 6a and the outer sub diaphragm 6b can be formed separately and later integrated by bonding, welding, or the like. . *
- the inner sub-diaphragm 6 a is firmly loaded in the case 3 by being fitted to the support frame 14 on the upper surface of the microphone holder 5, and an air chamber 16 is formed between the inner sub-diaphragm 6 a and the microphone holder 5.
- the inner sub diaphragm 6a is designed to have the same height as the skin contact portion 10 on the upper surface of the cover 4 or to protrude slightly more than that.
- the case 3 is a container having an open upper surface, and is usually made of a high specific gravity material such as brass, stainless steel, iron, and the like, and a hole 9 for drawing out a lead wire 8 coming out of the microphone unit 2 is formed in a lower portion of the side wall.
- the cover 4 is made of an elastic material having a good skin contact feeling, such as silicone rubber, and covers the case 3 with the upper surface opening portion being left.
- the upper end of the cover 4 is extended inward so as to cover the upper end surface of the case 3, and the inner extension portion becomes an annular skin contact portion 10.
- the cover 4 is also formed with a hole 11 corresponding to the hole 9 of the case 3 and communicating therewith, and the lead wire 8 is drawn out through the holes 9 and 11. *
