摘要： A diaphragm is gained by the co-molded of a dome part, a voice coil junction part, a cone part and a peripheral part through the injection mold of thermoplastic resin. The thickness of the central part of the dome is made great so that the resonance amplitude in this part becomes small. In addition, an annular rib is integrally provided to the voice coil junction part so as to increase the junction strength between the diaphragm and the voice coil bobbin. Thus, the electromagnetic driving force of the voice coil can be effectively transmitted to the diaphragm so that a loud speaker with excellent characteristics can be gained.

摘要： The surrounding structure of the loudspeaker forms an annular structure, including attaching parts and curved part. The cross section of the curved part is in a hollow and approximately elliptical form. The height along the major axis of the ellipse is made parallel to the center axis of the vibrating diaphragm of the loudspeaker while the width along the major axis of the ellipse is set in the direction orthogonal to the center axis of the vibrating diaphragm. In the elliptical surrounding structure having such a structure, the width in the cross section of the surrounding structure of the loudspeaker can be made narrow in comparison with a semi-circular surround, whereby the linearity of the amplitude and the maximum displacement are increased.

摘要： A damper 3A is provided with an inner peripheral waveform portion 11 and an outer peripheral waveform portion 12. A flat portion 10 is provided between the inner peripheral waveform portion 11 and the outer peripheral waveform portion 12. When the damper is used for a loudspeaker, the flat portion 10 does not elastically deform in a radial direction R, so that linearity of the damper 3A in a vibrating direction Z is ensured by elastic deformation of the waveform portions. In addition, a rolling phenomenon of a voice coil bobbin and a diaphragm can be suppressed.

摘要： A magnetic circuit for a loudspeaker includes a magnet and a top plate. The magnet is made of a bonded magnet. The magnet and the top plate are configured to satisfy at least one of conditions that an inner diameter of the magnet is identical to an inner diameter of the top plate, and that an outer diameter of the magnet is identical to an outer diameter of the top plate. This configuration eliminates a wasted space inside the magnetic circuit, and protrusion of the magnet to outside, hence providing a light and efficient magnetic circuit.

摘要： A speaker system according to the present invention comprises a cabinet (10), a speaker unit (11), a first parting board (12), a drone cone (13), an adsorption member (14), a second parting board (15), a backboard (16), a variable mechanism (17), and a port (18). A sound pressure generated by the speaker unit (11) causes a pressure variation in a second chamber (R12) via the drone cone (13). The adsorption member (14) with an effect of physical adsorption is operable to suppress the pressure variation. Furthermore, by displacing the diaphragm (171), the variable mechanism (17) is operable to reduce a pressure variation of a direct current component, which is caused by variations in ambient temperature or atmospheric pressure of the speaker system.
