<p>A loudspeaker has a chassis (104), a diaphragm (106), an actuator (108) and a sub-frame (110). The actuator (108) is coupled between the chassis (104) and a diaphragm (106). The sub-frame (110) is flexibly coupled to the chassis (104) and the diaphragm (106). The diaphragm (106) is flexibly suspended from the chassis (104). The actuator (108) directly drives both the diaphragm (106) and the sub-frame (110) through coils (130, 132) attached to the diaphragm (106) and to the sub-frame (110).</p> |
