Of course, the side edge may be disposed on any one of the other three side edges, which is not limited in this embodiment, and may be set according to actual situations.

It should be noted that the function key 5 in this embodiment refers to the volume key 51 and/or the power key 52 already existing on the mobile phone, and a gap existing between the function key 5 and the hole wall of the installation hole may be considered as an already existing gap (referred to as an existing gap for short) of the electronic device. The specific arrangement position and the operation principle of the function key 5 can refer to the prior art, and are not described in detail herein. That is, the previous function key is disposed on which side of the housing, and the sounding structure 4 of the present embodiment is disposed in the accommodating chamber at a position opposite to the function key 5.

In the prior art, since the length of the volume key 51 is greater than the length of the power key 52 in the length direction of the mobile phone, in order to make the sound generating structure 4 have better generating effect, as shown in fig. 2, when the distance between the volume key 51 and the power key 52 on the mobile phone is relatively long, the volume key 51 is regarded as the function key 5, and the piezoelectric ceramic plate 41 is disposed at a position opposite to the "volume key 51". At this time, the length of the function key 5 refers to the length of the volume key 51. Of course, the sound emitting structure 4 may be disposed at a position opposite to the power key 52, which is not limited in this embodiment, and the specific disposition position of the sound emitting structure 4 may be set according to actual conditions.
