て成るスピーカ。 In a speaker that is used in such a way that the output voltage of an acceleration sensor using a piezoelectric element that detects the acceleration of vibration of a diaphragm of a speaker is fed back to an amplifier that drives the speaker, a coil for driving the diaphragm is wound. The lead wire of the acceleration sensor attached to the center of the disk attached to the rotated cylindrical bobbin extends from the surface of the disk to the outer peripheral surface of the bobbin in an arc shape, A speaker connected to the eyelet on the diaphragm along the surface and further fixed to the disc, bobbin and diaphragm.
