专利汇可以提供Earphone pad专利检索，专利查询，专利分析的服务。并且An earphone pad for use in combination with an earphone structure that has a peripheral flange around its housing for supporting an earphone pad and a circular opening in the housing for communicating acoustical vibrations from an electroacoustical transducer within the housing to the ear of a user. The earphone pad has an outer ring of resilient material which is dimensioned to sealably engage the flange on the housing and provide an outer acoustical seal therearound and an inner ring of resilient material which is dimensioned to sealably engage the periphery of the opening in the housing to provide an inner acoustical seal therearound. The inner and outer resilient rings are joined together in substantially coaxial relationship by a relatively thin annular sheet of resilient material which constitutes the ear-engaging surface of the earphone pad. An annular pad of resilient material is positioned on the inside of this earengaging surface to provide an acoustical seal between the earphone housing and the ear of the user. The outer ring of resilient material, inner ring of resilient material, and the annular ear-engaging surface that joins the two rings together are preferably a unitary, molded structure which is made of surgical silicone plastic by an injection molding operation.，下面是Earphone pad专利的具体信息内容。

权利要求

1. An earphone pad for use in combination with an earphone structure including a housing member, an electroacoustic transducer mounted within said housing member, a substantially circular opening in one side of said housing member for communicating acoustical vibrations from within said electroacoustic transducer to the ear of a user, and a substantially circular flange around the periphery of said housing member for receiving and supporting an earphone pad to protect the ear of a user and to form an acoustic seal therearound, said earphone pad comprising an outer ring of resilient material and an inner ring of resilient material which are joined together in substantially coaxial relationship by a relatively thin annular sheet of resilient material, said outer ring of resilient material being dimensioned to sealably engage said flange to secure said earphone pad to said housing and to providE an outer acoustical seal therearound, said inner ring of resilient material being dimensioned to sealably engage the inner periphery of said opening in the side of said housing to provide an inner acoustical seal therearound, and an annular pad of resilient material positioned between said outer and inner resilient rings on the side of said annular sheet of resilient material which faces said housing for providing an acoustical seal between said housing and the outer ear of a user.

2. The earphone pad of claim 1 wherein said outer resilient ring contains a circular recess which is dimensioned to engage the outside periphery of said flange in said housing and an inwardly flanged end surrounding said circular recess which is dimensioned to engage the outer edge of said flange in said housing to secure said outer resilient ring to said housing.

3. The earphone pad of claim 2 wherein said circular recess is slightly smaller in diameter than said flange so as to fit snugly over said flange and provide an acoustical seal therearound.

4. The earphone pad of claim 3 wherein said inner resilient ring contains a circular recess which is dimensioned to engage the periphery of said opening in said housing and an outwardly flanged end surrounding said circular recess which is dimensioned to engage the inner surface of said housing around said opening to secure said inner resilient ring to said housing.

5. The earphone pad of claim 4 wherein said circular recess in said inner resilient ring is slightly smaller in diameter than said opening in said housing so as to fit snugly around the periphery of said opening and provide an acoustical seal therearound.

6. The earphone pad of claim 1 wherein said inner resilient ring, outer resilient ring, and relatively thin annular sheet of resilient material comprise a unitary molded structure.

7. The earphone pad of claim 6 wherein said inner resilient ring, outer resilient ring, and relatively thin annular sheet of resilient material comprise a unitary molded structure made of surgical silicone plastic.

8. The earphone pad of claim 1 wherein said annular pad of resilient material comprises an annular pad of surgical silicone sponge material.
