摘要

An electronic device includes (i) an input-volume measuring section (23) for measuring input volume, which is volume of a sound inputted into the sound input section (17) while the sound output section (16) is performing sound output, (ii) a feedback-volume estimating section (24) for estimating estimated volume, estimated volume is volume of a sound which is to be inputted into the sound input section (17) in a state in which there is no object which blocks the sound in a predetermined range, (iii) volume determination section (26) for determining whether or not the input volume is lower than the estimated volume, and (iv) a function control section (21) for carrying out a predetermined process if the input volume is lower than the estimated volume.

主权项

1. An electronic device including a sound output section and a sound input section, comprising:
a storage device; and a central processing unit performing steps of:
(a) measuring input volume, which is volume of a sound inputted into the sound input section while the sound output section is performing sound output;(b) estimating estimated volume in a reference state, estimated volume being volume of a sound outputted from the sound output section and is to be inputted into the sound input section, and the reference state being a state in which there is no object which blocks the sound outputted from the sound output section and is to be collected by the sound input section in a predetermined range defined by a position of one of the sound output section and the sound input section;(c) determining whether or not the input volume measured in step (a) is lower than the estimated volume estimated in step (b); and(d) carrying out a predetermined first process if the volume determination section step (c) determines that the input volume is lower than the estimated volume.
