发明名称 SPEAKER MAGNETIC CIRCUIT, SPEAKER DEVICE, AND METHOD OF MANUFACTURING SPEAKER MAGNETIC CIRCUIT
摘要 The present invention is to provide a speaker magnetic circuit which, even if small in its thickness, can reduce an occurrence of magnetic flux leakage so as to obtain a sufficient magnetic flux density in a magnetic gap, particularly in a position where a voice coil is supported. The speaker magnetic circuit (11) comprises a yoke (12) and a magnet group (13). The magnet group (13) comprises outer magnets (21-24) and inner magnets (25-28). The outer magnets (21-24) and the inner magnets (25-28) are magnetized in an oblique direction with respect to their thickness direction.
