Abstract

DISPOSITIVO DE ALTO-FALANTE. A presente invenção refere-se a um dispositivo de alto-falante plano capaz de emitir som reproduzido alto com uma configuração relativamente simples que é provido. O dispositivo de alto-falante inclui um diafragma, uma armação suportando o diafragma de maneira vibratória na direção de vibração, um circuito magnético disposto na armação e um elemento de acionamento para acionar o diafragma. O elemento de acionamento inclui uma bobina de som disposta de maneira móvel em uma abertura magnética do circuito magnético, uma parte de acionamento formada de maneira móvel em uma direção diferente da direção de vibração do diafragma e uma parte de conversão e transmissão de ângulo, uma extremidade da qual é unida com ângulo variável na parte de acionamento e uma outra extremidade da qual é unida com ângulo variável no diafragma. A parte de conversão e transmissão de ângulo tem rigidez e é obliquamente disposta com relação a cada uma da direção de vibração do diafragma e da direção de movimento da parte de acionamento.
