Anion earphone

An anion earphone comprises an earphone plug, an earphone line body, a boosting charging circuit, power generating units, a power generating unit connecting part, an anion generator and receivers. The power generating units supply electric power to the anion generator through the boosting charging circuit. The anion earphone has an energy-friendly and energy-saving performance. The power generating units are arranged on the surface of the earphone line body. Each power generating unit comprises a solar cell strip and a piezoelectric thin-film strip. The anions which are generated by the anion earphone with the energy-friendly and energy-saving performance can effectively purify air next to respiratory organs of a user, particularly has an obvious purification effect for harmful inhalable substances of smoke dust in smoking, etc. Solar energy is collected through equipping a flexible thin-film solar cell and a flexible piezoelectric material on an earphone line, and mechanical energy generated by deformation and pressure bearing of the earphone line is collected. Furthermore the collected solar energy and mechanical energy are converted to electric energy. The converted electric energy is used for driving the anion generator to generate anions for purifying air and charging electronic products of mobile phone, etc.
