MOVING-MAGNET LOUDSPEAKER AND METHOD FOR MANUFACTURING SAME |
摘要 |
<p>Provided is a thin moving-magnet loudspeaker in which a quantitative guideline has been established for the mass of a magnetic circuit, and increases in the inductance of a voice coil are suppressed while maintaining the magnetic flux density of a voice coil. The moving-magnet loudspeaker (10) is configured such that: a diaphragm (1) having a magnetic circuit consisting of a magnet (5) and a magnetic body (4) is made to vibrate so as to generate sound by means of the magnetic circuit according to the magnetic field generated by a voice coil (6) through which a sound current flows; and the total mass of the magnetic circuit is 0.5 to 2.0 times the total mass of an additional mass and the mass of the diaphragm (1). In addition, the voice coil (6) is divided into a plurality of portions so as to reduce the inductance thereof and prevent the reduction of the sound current in a high-pitched sound range.</p> |
