Abstract

La presente exposición describe un aparato de emisión acústica. El aparato de emisión acústica puede incluir un controlador acústico. El controlador acústico puede incluir un diafragma y una estructura de circuito magnético. Puede formarse un lado frontal del controlador acústico en un lado del diafragma alejado de la estructura del circuito magnético. Puede formarse un lado posterior del controlador acústico en un lado de la estructura del circuito magnético alejado del diafragma. El diafragma puede vibrar para hacer que el controlador acústico irradie sonido hacia el exterior desde el lado frontal y el lado posterior del controlador acústico. El aparato de emisión acústica puede incluir además una estructura de alojamiento configurada para contener el controlador acústico. Un lado del lado frontal y el lado posterior del controlador acústico pueden formar una cavidad con la estructura de alojamiento. El lado del controlador acústico que forma la cavidad puede irradiar el sonido hacia la cavidad, y el otro lado del controlador acústico puede irradiar el sonido hacia el exterior del aparato de emisión acústica.
