In another embodiment (not illustrated), a recess or an opening may be formed in a part of the screen display area of the display 101, and at least one of an audio module 114, a sensor module 104, a camera module 105, and a light-emitting element 106 may be included and aligned with the recess or the opening. In another embodiment (not illustrated), on the back surface of the screen display area of the display 101, at least one of an audio module 114, a sensor module 104, a camera module 105, a fingerprint sensor 116, and a light-emitting element 106 may be included. In another embodiment (not illustrated), the display 101 may be coupled to or arranged adjacent to a touch sensing circuit, a pressure sensor capable of measuring the intensity (pressure) of a touch, and/or a digitizer that detects a magnetic field-type stylus pen. In some embodiments, at least a part of the sensor modules 104 and 119 and/or at least a part of the key input device 117 may be arranged in the first areas 110D and/or the second areas 110E.

The audio modules 103, 107, and 114 may include a microphone hole 103 and speaker holes 107 and 114. A microphone for acquiring external sound may be arranged in the microphone hole 103, and a plurality of microphones may be arranged therein such that the direction of the sound can be detected in some embodiments. The speaker holes 107 and 114 may include an outer speaker hole 107 and a speech receiver hole 114. In some embodiments, the speaker holes 107 and 114 and the microphone hole 103 may be implemented as a single hole, or a speaker may be included (for example, a piezoelectric speaker) without the speaker holes 107 and 114.
