发明名称 LINEAR VIBRATOR HAVING A VIBRAING PART WITH EASY ASSEMBLY
摘要 <p>The present invention provides a linear oscillator having an improved structure for assembly and thus making it possible to skip an additional bond coating process as the oscillator has a shape fitting structure for assembling a vibration unit like a permanent magnet, a top plate, a yoke, and a weight member. The present invention provides a linear oscillator, which has an improved structure for assembly of a vibration unit and is composed of: a case with a cylindrical side wall and a circular front face; a cover case coupled to the bottom of the case; a permanent magnet installed in a space defined by the case and the cover case; a weight member fitted with the permanent magnet; a yoke fitted with the weight member; and a voice coil attached on the cover case. One end of the voice coil is positioned at a vibration unit for elastically supporting the vibration unit which comprises the permanent magnet, the yoke, and the weight member. The other end of the voice coil is positioned between a spring fixed on the front face of the case, a side wall of the case, and the permanent magnet.</p>
