The connection of two spaces 220.
In the embodiment shown in fig. 6, third sealing element 173 be set to battery 160 towards shell 110 cover board one
Side, third sealing element 173 are connect with the cover board of shell 110 and cell sealing respectively, so that third space 230 is divided into first
Subspace 231 and the second subspace 232.Since battery 160 generates heat in electronic device works, third sealing element 173 is needed
The material of preferable heat resistance, third sealing element 173 can be the high temperature resistants materials such as silica gel, butyl rubber.
In embodiment shown in fig. 6, the back cavity of the first loudspeaker monomer 140 includes the first space 210, the first space 210
Gap and the first subspace 231 between the first subspace 231.The back cavity of second loudspeaker monomer 150 includes second empty
Between gap and the second subspace 232 between 220, second space 220 and the second subspace 232.By by third sealing element
173 are set on battery 160, so that the back cavity of the first loudspeaker monomer 140 and the second loudspeaker monomer 150 both increases part
Third space 230 is not only promoted to increase the back cavity volume of the first loudspeaker monomer 140 and the second loudspeaker monomer 150
The utilization rate of accommodating space in electronic equipment also optimizes electronic equipment and issues stereosonic sound quality.
Further, the sum of volume of first subspace 231 and the first space 210 is equal to second subspace
232 with the sum of the volume of second space 220.
Due to many electronic devices that needs to arrange in the limited accommodating space of electronic equipment, in accommodating space each device it
Between arrangement density it is high, therefore the gap very little between the first space 210 and the first subspace 231, the space are raised as first
A part of the back cavity of sound device monomer 140, the influence to sound can be ignored, the back cavity pair of the first loudspeaker monomer 140
The influence of sound depends primarily on the volume size in the first space 210 and the first subspace 231.Likewise, the second loudspeaker list
The back cavity of body 150 depends primarily on the volume size of second space 220 and the second subspace 232 to the influence of sound.
By the way that the sum of the volume in the first space 210 and the first subspace 231 is designed to and second space 220 and the second son
The sum of the volume in space 232 is equal, so that sound and the second loudspeaker monomer 150 that the first loudspeaker monomer 140 issues
The sound equalization of sending improves the stereosonic counterbalance effect that electronic equipment issues.
Optionally, please refer to Fig. 7 and Fig. 8, the accommodating space includes third space 230, the third space 230
For space of the battery 160 between the cover board of the shell 110, first space 210, the second space 220
