摘要： A 1/4 wave length coaxial resonator comprises an outer cylindrical portion, an inner cylindrical portion positioned coaxially in the outer cylindrical portion, with the outer and inner cylindrical portions connected at one end by a radial connecting portion, and a dielectric unit disposed therebetween. The outer cylindrical portion and the inner cylindrical portion and the radial connecting portion are formed with a unitary member of a metallic extruded material formed by means of an impact extruding process so that the inner cylindrical portion is positioned coaxially in the outer cylindrical portion. As a result, a space is formed between the outer cylindrical portion and the inner cylindrical portion to allow for insertion of a hollow cylindrical dielectric unit. One end of the above described metallic extruded member of a unitary material is formed as an opened end allowing for insertion of the dielectric unit, while the other end of the metallic extruded member is formed as a radial connecting portion for electrically short-circuiting the outer cylindrical portion and the inner cylindrical portion. The dielectric unit is formed with an outer conductor layer on the outer wall surface and an inner conductor layer on the inner wall surface. The dielectric unit is inserted only in the region close to the opened end or in the whole portion of the space between the outer cylindrical portion and the inner cylindrical portion.

摘要： A sound insulator of the invention includes a sound absorption layer 202 and an air-impermeable resonance layer 203, which are bonded to each other via an adhesive layer 204. The sound absorption layer 202 has a thickness in a range of 5 to 50 mm and an area-weight of not greater than 2000 g/m2. The sound absorption layer 202 has a two-layer structure of a high-density sound absorption layer 202a and a low-density sound absorption layer 202b, which have different densities. The high-density sound absorption layer 202a is bonded to the air-impermeable resonance layer 203 via the adhesive layer 204 and has a density in a range of 0.05 to 0.20 g/cm3 and a thickness in a range of 2 to 30 mm. The low-density sound absorption layer 202b is bonded to the other face of the high-density sound absorption layer 202a, which is opposite to the air-impermeable resonance layer 203, via an adhesive layer 202c and has a density in a range of 0.01 to 0.10 g/cm3 and a thickness in a range of 2 to 30 mm. The structure of this sound insulator effectively reduces a noise level in a voice-tone frequency band, especially in a high frequency domain, thereby efficiently enhancing the clarity of conversion in a vehicle interior.
