Abstract

Se describe un dispositivo acústico que comprende: un componente piezoeléctrico que vibra bajo la acción de un voltaje de activación; un componente de vibración que se conecta mecánicamente al componente piezoeléctrico para recibir una vibración y producir sonido; y un elemento resistor que se conecta en serie con el componente piezoeléctrico para cambiar la respuesta de frecuencia del componente de vibración, en donde el elemento resistor hace una diferencia entre una amplitud de vibración del componente de vibración a 10 kHz y una amplitud de vibración del componente de vibración a 1 kHz menor o igual a 20 dB. El elemento resistor se conecta en serie, de tal manera que puede reducirse la amplitud de vibración del componente de vibración en las bandas de frecuencia media y alta, puede reducirse la diferencia de sensibilidad de la banda de frecuencia completa y puede mejorarse la ecualización de frecuencia alta y baja de la salida de sonido del dispositivo acústico. Además, cuando el dispositivo acústico se encuentra en las bandas de frecuencia media y alta, el elemento resistor conectado en serie también puede reducir la corriente que fluye a través del componente piezoeléctrico por división de voltaje, reduciendo así la energía térmica generada por el componente piezoeléctrico, logrando el efecto del control de temperatura, y mejorando la confiabilidad de operación del dispositivo acústico.
