摘要： In a speaker, a lead wire at the end of the coil wire of a voice coil vertically runs through the interior of a notch and/or above the notch provided in a yoke even when a clearance between a diaphragm and the yoke is small, and does not run into the yoke. Therefore, the speaker can be thinned without causing troubles such as abnormal noise and a broken line at the end of a coil.

摘要： An uncured fluid adhesive is charged into a groove surrounding the outer circumference of a voice coil so that the inner circumferential edge of a diaphragm is immersed in the adhesive. The cured adhesive securely bonds the diaphragm to the voice coil, and thus the diaphragm can be driven at high output.

摘要： A voice coil bobbin (16), which transmits a motive force from the voice coil (17) wound around the bobbin to a diaphragm (18), includes a main part (161), a reinforcement part (163) formed on the surface side of the main part, and a middle part (162) formed between the main part and the reinforcement part and made of a material which has a lower density than the other two parts, preferably a non-woven cloth. Thus, there can be provided with the simple-design, high-rigidity voice coil bobbin (16) with high internal loss and a speaker system (1) capable of high-quality sound reproduction.

摘要： A speaker device having, roughly speaking, a cabinet (1) and a speaker unit (2a). The speaker unit (2a) is attached to an opening formed in the front face of the cabinet (1). The speaker unit (2a) has a rear face frame (3a), a front face frame (4a), a first magnetism circuit (5a), a second magnetism circuit (6a), an edge (7a), a damper (8a), a vibration plate (9a), a voice coil bobbin (10a), and a voice coil (11a). A non-magnet member (91a) constructing a part of the vibration plate (9a), the first magnetism circuit (5a), and the second magnetism circuit (6a) function as a negative stiffness mechanism to suppress the effect of acoustic stiffness, realizing a the speaker device small sized and capable of reproducing a deep sound.

摘要： A damper, which is an element of a speaker and suppresses the rolling of a voice coil unit, includes a corrugated structure portion at its inner periphery and a leaf spring at its outer periphery. By coupling the corrugated structure portion to the voice coil unit and coupling the leaf spring to the frame, the distortion of a speaker can be reduced and the driving efficiency can be improved.
