Abstract

In a folding electronic device, a pair of micro-speakers is mounted in the upper housing, and a vibrating actuator is mounted in the lower housing. Both these micro-speakers and the vibrating actuator reproduce sound. The vibrating actuator causes the lower housing and external housing to vibrate, and in particular supplements the acoustic characteristics of the micro-speakers in the low-frequency region. Furthermore, in cases where sound is reproduced using the mobile terminal device constituting this electronic device, sound is reproduced by mounting the mobile terminal device in an external housing, charging device, or cradle.
