Title: Electronic apparatus and acoustic distance measurement method thereof
Inventor: LIU HAODONG
IPC: G01S15/08
Filed: 2018-05-04
Abstract: Disclosed in embodiments of the present application are an electronic apparatus and an acoustic distance measurement method thereof. The acoustic distance measurement method comprises: transmitting a dual-tone multi-frequency signal, i.e., transmitting a first acoustic signal including a first frequency signal and a second frequency signal; and performing a computation according to a difference in period between the first frequency signal and the second frequency signal in a first received signal corresponding to the first acoustic signal so as to obtain a distance between an electronic apparatus and a target obstacle. In this way, the present invention avoids the problem in which a transmission time and receiving time of acoustic signals overlap, causing difficulties in acquiring a measurement result. In addition, harmonic waves in an audible range do not exist after mutual modulation of the first frequency signal and the second frequency signal, thus preventing the acoustic signal from creating a popping sound audible to the human ear (said popping sound being a crackling sound of an audio sub-system and being a type of interference signal), thus improving user experience.
