ABSTRACT:
An electronic product has a function knob capable of receiving voice signals. The electronic product includes a case forming the product's external appearance and is provided with the function knob for performing a given function of the product. A microphone is installed in the function knob to operate a given function and receive the voice signals. The function knob has a dustproof rubber member to shield the overall surface of the microphone other than the front side of the function knob from dusts and noises. The function knob, with the microphone installed therein, can be a button operated by a press or a dial by a rotation, thereby allowing the microphone to be highly sensitive to the voice signals but not spoiling the external appearance of the product.
