    Abstract: Disclosed are an electronic device and method for detecting the proximity of an object. In an embodiment, the electronic device includes a communication module, a sound emitter, a sound receiver, and a processor. The processor receives at least one part of a voice signal from a calling party through the communication module, and determines whether there is a voice idle time in the at least one part of the voice signal. When the voice idle time is present in the at least one part of the voice signal, the processor outputs a sound wave in an inaudible frequency band through the sound emitter during the voice idle time. Then the processor receives, through the sound receiver, sound wave in the inaudible frequency band reflected from an object. Next, the processor may detect whether the object is proximate to the electronic device using the reflected sound wave in the inaudible frequency band.

    Abstract: An electronic device includes a light emitter emitting visible light, an infrared emitter emitting infrared light, at least one detector detecting an electromagnetic wave, and at least one processor configured to obtain a user input to obtain spectral data of a target object, in response to obtaining the user input, emit the visible light by using the light emitter and emit the infrared light by using the infrared emitter, obtain a first reflected signal of the visible light reflected by the target object and a second reflected signal of the infrared light reflected by the target object, using the at least one detector, and generate the spectral data of the target object based on the first reflected signal and the second reflected signal.
