PURPOSE:To provide a loudspeaker thin in depth and a wide range sound reproducing frequency characteristic by constituting the titled speaker of a diaphragm having a vibration moving part obtained by disposing the desired number of vibrating elements in serial, a casing made of magnetic material, and a magnetic base obtained by disposing the desired number of vibration elements in series which forms a magnetic gap. CONSTITUTION:The magnetic base 1 is constituted of a magnetic board 11, permanent magnet 12, and a top yoke 13. On the magnetic board 11, plural holes 11a are drilled and form a bottom 11b and side yokes 11c and 11c. A vibrator 2 is constituted of a diaphragm 21 and voice coil 22. The diaphragm 21 is constituted of a vibrating moving part consisting of vibrating elements aligning in slender form in series, edge 21b, and a clamp 21c. The edge 21b is of convex form and to its upper part are continuously attached with elastic elements 21b'. Around respective vibrating elements 21a, the voice coil 22 is wound. In such configuration above, the elastic elements 21b provide the diaphragms 21 with a high complience. Also, because the entire range of the vibration moving part is driven uniformly, slender constitution is free from any problem. |
