Electronic device with reflection structure for reflecting optical signal to receiver thereof
The electronic device includes a device housing, an emitter, a receiver, and a reflection structure. The emitter is separated from the device housing and emits an optical signal. The receiver is disposed on the device housing for receiving the optical signal. The reflection structure is formed on the device housing and neighboring to the receiver. When the emitter is disposed in front of the device housing, the optical signal transmitted from the emitter is reflected by the reflection structure, and then the optical signal travels toward the receiver.
