Abstract

um dispositivo acústico compreende: um componente piezoelétrico 120 que vibra sob a ação de uma tensão de condução; um componente de vibração 110 que é conectado mecanicamente ao componente piezoelétrico 120 para receber uma vibração e produzir som; e um elemento resistor 130 que está conectado em série com o componente piezoelétrico 120 para alterar uma resposta de frequência do componente de vibração 110, em que o elemento resistor 130 faz uma diferença entre uma amplitude de vibração do componente de vibração 110 em 10 khz e uma amplitude de vibração do componente de vibração 110 em 1 khz menor ou igual a 20 db. o elemento resistor 130 é conectado em série, de modo que a amplitude de vibração do componente de vibração 110 em bandas de frequência média e alta pode ser reduzida, uma diferença de sensibilidade da banda de frequência total pode ser reduzida e a equalização de frequência alta e baixa de a saída de som do dispositivo acústico pode ser melhorada. além disso, quando o dispositivo acústico está nas bandas de média e alta frequência, o elemento resistor conectado em série também pode reduzir a corrente que flui através do componente piezoelétrico 120 por divisão de tensão, reduzindo assim a energia térmica gerada pelo componente piezoelétrico 120, alcançando o efeito do controle de temperatura e melhorando a confiabilidade da operação do dispositivo acústico.
