Abstract

"APARELHO DE FONE DE OUVIDO ESTEREOFÈNICO", revelado para inserção no canal auditivo do usuário. O aparelho inclui uma caixa, que tem primeira e segunda extremidades e que define um invólucro. Um transdutor eletroacústico está disposto dentro do invólucro e um diafragma está disposto dentro do invólucro adjacente ao transdutor. Uma âncora resiliente, tendo primeira e segunda extremidades, é disposta de modo que a primeira extremidade é presa removivelmente na tampa da caixa e dela se estende. A âncora é fabricada de espuma de uretano hidrofílica, tendo uma superfície externa revestida, de modo que, quando a âncora for comprimida é permitida inserção da âncora dentro do canal auditivo. A espuma tem uma memória de restauração da forma, de modo que, depois da inserção da âncora dentro do canal auditivo, a espuma expande-se gradualmente de modo que sua superfície revestida entra em contato estrito com o canal auditivo, de modo que o aparelho fica preso dentro do canal auditivo. Um tubo se estende da tampa e está colocado dentro de uma passagem definida pela âncora. O tubo tem uma face interna e uma face externa de modo que a face externa do tubo estende-se contiguamente ao longo da passagem de modo que o tubo impede obstrução da passagem enquanto permite a transmissão de ondas sonoras do diafragma para o canal auditivo."STEREOPHONE HEADPHONE", revealed for insertion in the user's ear canal. The apparatus includes a box, which has first and second ends and which defines a housing. An electroacoustic transducer is disposed within the enclosure and a diaphragm is disposed within the enclosure adjacent to the transducer. A resilient anchor, having first and second ends, is arranged so that the first end is removably attached to and extends from the box lid. The anchor is made of hydrophilic urethane foam, having a coated outer surface, so that when the anchor is compressed it is allowed to insert the anchor into the ear canal. The foam has a shape restoration memory, so that, after the anchor is inserted into the ear canal, the foam gradually expands so that its coated surface comes into strict contact with the ear canal, so that the hearing aid gets stuck inside the ear canal. A tube extends from the cover and is placed within a passage defined by the anchor. The tube has an inner face and an outer face so that the outer face of the tube extends contiguously along the passage so that the tube prevents obstruction of the passage while allowing the transmission of sound waves from the diaphragm to the ear canal.
