A clamshell or clamshell mobile is a mobile phoneform
factor where the
phone is divided into two equal halves with a hinge connecting the halves,
enabling users to basically fold the phone in half to close when not in use.
This type of mobile phone usually has the buttons on the bottom
half and the display and speaker on the top half. Some clamshell mobiles may
also have a small display on the outside, so when the phone is folded you can
view connection details, incoming calls and the date and time without opening
the phone.
Clamshell phones are more frequently called a flip phone. Flip phone
is used in everyday language as a generic term, however
Motorola owns the trademark on the term flip phone.
