Abstract
PURPOSE:To prevent a problem of lowering a speaker sound pressure level or an adverse influence to the mechanism of a vehicle due to the leakage of a magnetism by providing a magnet for preventing the leakage of the magnetism between the fitting and a speaker unit. CONSTITUTION:The fitting 2, the magnet 4 for preventing the leakage of the magnetism are held by a screw 3 to the tapped hole of a plate with the pole piece of the speaker unit 1. Then, the speaker is mounted on a vehicle through the fitting 2. Thereby, a magnetic energy to be leaked to the direction of the fitting from the plate with the pole piece of the speaker unit is repulsed by the repulsion of the N pole and the S pole of the magnet with the magnetic energy of the magnet for preventing the leakage of the magnetism having an anisotropic characteristic in a B direction, the magnetic flux density of a speaker gap is not reduced not the speaker output sound pressure level is changed even mounting the fitting. Since there is no leakage of the magnetism to the fitting, an effect for applying no adverse influence to the mechanism of the vehicle is generated.
