Abstract
A multifunctional earphone is disclosed. The multifunctional earphone includes a main body having an electroacoustic element incorporated therein for serving as an earphone, an ear-insertion body having a sound tube portion bonded with the main body, a wing portion extending around from the sound tube portion, and an acceleration sensor serving as a microphone embedded in the wing portion and formed a configuration such that the outer periphery of the wing portion contacts an external auditory meatus of a user's ear. The acceleration sensor includes a substrate directly or indirectly contacting with a vibration source, a spring connecting with the substrate, a weight and a piezoelectric element deformed by an external force from the weight, by which the piezoelectric element produces an electric energy based on piezoelectricity effect.
