In such a case, once the baby device 110 disconnects the communication with the parent device 120, the guardian who holds the parent device 120 will not be able to obtain the state information of the monitored baby; once the baby device 110 disconnects the communication with the portable device, the guardian who holds the portable device will not be able to obtain the state information of the monitored baby.

[0045] In some embodiments, when the baby device 110 receives the first feedback audio transmitted by the parent device 120 and the second feedback audio transmitted by the portable device at the same time, the first playing module 113 may play one of the first feedback audio and the second feedback audio (which is also referred to as a target feedback audio), and put the other of the first feedback audio and the second feedback audio (which is also referred to as a non-target feedback audio) on mute, so as to prevent the first playing module 113 from playing the non-target feedback audio. In this way, the baby device 110 may selectively play the first feedback audio or the second feedback audio without disconnecting the communication between the baby device 110 and the parent device 120 and the communication between the baby device 110 and the portable device. In such a case, both the guardian holding the parent device 120 and the guardian holding the portable device may obtain the state information of the monitored baby.

[0046] In some embodiments, the first playing module 113 may set the volume of the non-target feedback audio to be 0 to put the non-target feedback audio on mute. For example, the first playing module 113 may set the volume of the non-target feedback audio to be 0, mix the non-target feedback audio of which the volume is set to be 0 with the target feedback audio to obtain a mixed audio, and play the mixed audio.

[0047] In some embodiments, the first playing module 113 may also discard the non-target feedback audio to put the non-target feedback audio on mute, which is not limited by the embodiments of the present disclosure, and those skilled in the art may choose according to actual needs.
