Vibrator and portable terminal device mounted with the vibrator

摘要

In order to improve the reliability of an electrical connection between a power supply terminal of a vibrator and an electrode of a circuit board and to improve the efficiency of mounting the vibrator on the circuit board, the power supply terminal is made from a torsion coil spring and a contact portion of the power supply terminal in contact with the electrode of the circuit board is formed by winding. In addition, a torsion coil spring portion is wound around a spindle pin and a housing is provided with a step portion as a space for accommodating the contact portion without interference and a plane portion to which the contact portion faces. Moreover, a partition plate is provided between a pair of power supply terminals or a space where the contact portion can be elastically deformed is surrounded by a box member, a pair of power supply terminals having positive and negative polarities are extended in a bilaterally symmetric direction from torsion coil spring portions to the contact portions, and the power supply terminals are constructed so as to be elastically deformed to allow each contact portion to reach the outside of each torsion coil spring portion.
