Therefore, the microphone 60 of the mobile phone 1 can easily pick up external sounds.
[0040]
Therefore, it is possible to provide a user with a comfortable call even during a hands-free call.
[0041]
In the present embodiment, a configuration in which the mobile phone 1 can be charged in a folded state is described, but a configuration in which a straight type mobile phone is charged in a vertical direction may be used.
[0042]
In a foldable mobile phone, if charging is performed in a folded state, the microphone hole may be blocked by the housing, and the microphone may not be able to sufficiently pick up the voice of the user. However, in a straight type mobile phone, the microphone hole is usually formed not only near the bottom of the housing but also the microphone hole is always exposed, so when charging the straight type mobile phone vertically, It goes without saying that the microphone of a mobile phone is easier to pick up external sounds than a foldable mobile phone.
[0043]
Also when charging such a straight type mobile phone, external sound is easily transmitted to the microphone of the mobile phone through the microphone hole 590 of the charging unit 500.
[0044]
【The invention's effect】
The present invention makes it possible to provide a comfortable hands-free call.
