摘要： There are provided a headphone and an electrodynamic speaker unit exhibiting proper vibration characteristics and excellent reproduced sound quality. First, second, and third coupling portions of a frame of the headphone defining adjacent two opening holes extend from a magnetic circuit fixing portion to a diaphragm fixing portion such that each of the first, second, and third coupling portions is inclined with respect to a radial line passing through a center point, and are formed such that a first separation distance between the first coupling portion and the second coupling portion and a second separation distance between the second coupling portion and the third coupling portion in a circumferential direction are different from each other and that the opening hole areas of at least two opening holes are unequal to each other.

摘要： A loudspeaker diaphragm includes a diaphragm portion and an edge portion, which is molded integrally with the diaphragm portion and made of a material different from a material for the diaphragm portion. The edge portion contains at least one thermoplastic polymer (I), in combination with a block polymer (II). The at least one thermoplastic polymer (I) is selected from a block copolymer (I-a) which contains a polymer block (A) having a repeating structural unit derived from an aromatic vinyl compound and a polymer block (B) having a repeating structural unit derived from a conjugated diene, and an addition hydrogenated block copolymer (I-b) of the block copolymer (I-a). The block copolymer (II) contains a polymer block (C) having a repeating structural unit derived from an olefin compound and a polymer block (D) having a repeating structural unit derived from a (meth)acrylic compound.

摘要： Provided is a speaker diaphragm being able to reduce disturbance of sound pressure frequency properties of a high-tone range including an extremely high-tone range while reducing a manufacturing cost, a speaker including the speaker diaphragm, and the method for manufacturing the speaker diaphragm.A diaphragm 30 includes a dome portion 32 vibratably supported by a speaker body 11 through an edge 14 and protruding in a Z-axis direction, and an annular cone portion 34 extending from an outer peripheral edge of the dome portion 32 in the direction inclined with respect to the Z-axis direction. The dome portion 32 and the cone portion 34 are, in a seamless manner, integrally made of magnesium or magnesium alloy, and an outer peripheral end of the cone portion 34 extends to the substantially same height position as the height P of the maximum protrusion position of the dome portion 32. An annular step portion 36 for attachment of a cylindrical voice coil bobbin 17 is provided along a boundary portion between the dome portion 32 and the cone portion 34.

摘要： An electrodynamic speaker in which the number of steps of forming a tinsel wire to be connected to a voice coil and connecting the tinsel wire to a terminal can be reduced is provided.A frame of the electrodynamic speaker includes an edge mounting section, a magnetic circuit mounting section, a coupling section for coupling the edge mounting section and the magnetic circuit mounting section so as to define a plurality of window sections, a terminal fixing section for fixing a terminal, and at least one void for dividing the edge mounting section having an approximately annular shape, the void being communicatively connected to the window sections of the coupling section. A middle portion of the tinsel wire passes through the void or the window sections communicatively connected to the void, and the other end of the tinsel wire is connected and fixed to the terminal.

摘要： An edge portion of a diaphragm is configured such that multiple recessed ribs formed by recessing of a raised surface are provided in an inclination direction inclined with respect to a radial line passing through a center point and are arranged rotationally symmetrically, and among the recessed ribs and a fixing portion defined on the outermost peripheral side of the diaphragm, defines an outer peripheral edge portion at which no recessed ribs are formed. A voice coil is coupled to a voice coil attachment portion. A lead line is fixed with a first adhesive forming a first adhesive layer along a valley portion defined between a certain recessed rib and an adjacent recessed rib thereof on a back side of the edge portion, and is further fixed with a second adhesive forming a second adhesive layer with the lead line being curved along the outer peripheral edge portion.

摘要： A speaker diaphragm includes a protruding dome portion formed at a center portion of the speaker diaphragm, and an annular cone portion extending from an outer peripheral edge of the dome portion in a direction inclined with respect to a protrusion direction of the dome portion. The dome portion and the cone portion are, in a seamless manner, integrally formed of a sheet material made of magnesium or magnesium alloy, and an outer peripheral end of the cone portion at least extends to a substantially identical height position to a maximum protrusion position of the dome portion. An annular step portion for attachment of a cylindrical voice coil bobbin is provided along a boundary portion between the dome portion and the cone portion.
