Abstract
"CIRCUITO DE CONTROLE E MéTODO PARA UMA ADAPTAçãO DE RESPOSTA DE FREQuêNCIA DEPENDENTE DE INFORMAçãO DA INTENSIDADE DO SINAL DE UM SINAL DE áUDIO PARA UM TRANSDUTOR ELETRODINâMICO, E, TERMINAL DE TELECOMUNICAçãO MóVEL". é descrito um circuito de controle para uma adaptação de resposta de freq³ência dependente de informação de intensidade do sinal de um sinal de áudio para um transdutor eletrodinâmico (4), com um dispositivo de determinação de informação de intensidade do sinal (2, 6) para determinar uma informação de intensidade do sinal de acordo com o nível de sinal de áudio, e um dispositivo modificador (3) para modificar seletivamente a freq³ência do sinal de áudio em resposta à informação da intensidade do sinal, de maneira tal que o transdutor eletrodinâmico (4) converta o sinal de áudio em um sinal de som de baixa distorção para altos níveis de sinal de áudio, e com uma resposta de freq³ência uniforme para baixos níveis de sinal de áudio, por meio do que uma faixa de freq³ência mais baixa do sinal de áudio é modificada, com um ganho diferente de um ganho de uma faixa de freq³ência mais alta do sinal de áudio, e uma freq³ência que separa a faixa de menor freq³ência da faixa de maior freq³ência é deslocada para valores mais altos para um nível crescente do sinal de áudio, e para valores mais baixos para um nível decrescente do sinal de áudio. A presente invenção propõe adicionalmente um terminal de telecomunicação móvel com um circuito de controle projetado de maneira correspondente.
