Abstract

PURPOSE:To improve performance and to reduce cost by forming magnetic circuits with a common magnetic gap by using two magnetic cores that have the magnetic gap extending in parallel to a center axis and then by combining those two magnetic cores so that the both will cross at right angles each other. CONSTITUTION:Magnetic core 21 is formed of one body of pole piece parts 22a and 22b and yoke parts 23a-23c, which are made of ferrite. Magnetic core 26 is similar to magnetic core 21 and has pole piece parts 27a and 27b and yoke parts 28a-28c. Magnetic cores 21 and 26 are arranged crossing at right angles and in common magnetic gap 31, vibrator 32 supported with free angular motion is provided. Then, magnetic cores 21 and 26 are provided with left and right electricity generating coils 25 and 30 respectively.
