Provided is a mobile terminal. The present application provides a sensor inside either or both of a receiver opening and a microphone opening, rather than providing an additional opening on the front panel of a device for installing the sensors, such that light is transmitted to the sensor via the receiver opening and/or the microphone opening, and the sensor transmits a signal via the receiver opening and/or the microphone opening; the receiver opening and/or the microphone opening are openings currently available on the front panel of the device, without the need of proving additional openings on the front panel of the device, reducing the number of the openings on the front panel of the device to make a mobile device more integrated, and provide a better user experience due to an uncluttered surface of the front panel of the device.
