Abstract:
The present application relates to the field of electronic devices and relates to an electronic device. The electronic device comprises a first sound generating apparatus and a second sound generating apparatus; and a part of the sound cavity wall of a sound cavity of the second sound generating apparatus is common with a part of the sound cavity wall of a sound cavity of the first sound generating apparatus and/or a part of the channel wall of a sound transmission channel so as to constitute a common wall. The existence of the common wall makes the first sound generating apparatus and the second sound generating apparatus be combined together to form an electroacoustic device assembly, thereby improving the overall loudspeaker effect of the electronic device and also saving the structure space of the electronic device.
