Patent number: 10418010Abstract: A device case includes speaker boxes that are formed inside spaces created by placing upper cases that have a larger external shape than a lower case on upper of that lower case, as well as box connectors that are arranged fitting into the speaker boxes in the upper cases so as to contact the ends of peripheral portions of the lower case and fix together the lower case and the upper cases. This makes it possible for the box connectors to seal the spaces between the peripheral portions of the lower case and the peripheral portions of the upper cases. This, in turn, makes it possible to reliably and satisfactorily seal the speaker boxes in an airtight manner even when the external shapes of the lower case and the upper cases that are stacked together are different.Type: GrantFiled: January 18, 2017Date of Patent: September 17, 2019Assignee: CASIO COMPUTER CO., LTD.Inventor: Akihisa Hoshino
