  The speaker unit 300 is assembled to the speaker frame 210 in which the first conductive member 231, the second conductive member 232, and the third conductive member 233 are injection molded by insert molding in advance. In other words, the attachment flange 312 of the diaphragm 310 provided with a voice coil bobbin in advance is attached to the attachment step 213A of the speaker frame 210 with an adhesive or the like, and the magnetic circuit part is disposed in the speaker holding part 215. The unit 300 is assembled and formed on the speaker frame 210. That is, the speaker frame 210 functions as a so-called cabinet baffle plate to which the speaker unit 300 is attached, and also functions as a so-called frame of the speaker unit 300. When the speaker unit 300 is assembled and formed, the lead wire of the voice coil is drawn out from the insertion hole 215A of the speaker holding part 215 to the outer surface side of the speaker holding part 215.

  Then, the lead wire of the voice coil is connected to the first lead wire connection portion 231B of the first conductive member 231 and the third lead wire connection portion 233B of the third conductive member 233 of the speaker frame 210 to the electric wire connection hole 231D.

The speaker device 100 is assembled and formed by attaching the cover body 220 integrally so as to cover the other surface side of the speaker frame 210.

[Effects of Embodiment]
As described above, in the above embodiment, the speaker holding unit 215 that holds the speaker unit 300 including the voice coil that vibrates the diaphragm 310 and the network component 400 that controls the electric signal supplied to the speaker unit 300 are provided. A plate unit 211 having a component holding unit 216 for holding, and a first conductive member 231 having one end connected to the network component 400 and the other end connected to the voice coil of the speaker unit 300 are formed integrally. A frame 210 is formed. Therefore, the voice coil of the speaker unit 300 held by the speaker holding unit 215 and the network component 400 held by the component holding unit 216 are connected to each other only by connecting to the first conductive member 231 provided integrally. Thus, the assembly workability can be easily improved.

  And as the board part 211 provided with the speaker holding | maintenance part 215 and the component holding | maintenance part 216, it integrally forms with the resin material. Therefore, an integrated configuration for holding the speaker unit 300 and the network component 400 can be easily formed by, for example, injection molding or the like, and the first conductive member 231 is integrally formed by, for example, insert molding or the like. Can be formed. Furthermore, since a resin material having insulation properties and a relatively hard resin is used as the resin material, even if the conductive members 231 to 233 are integrally formed, a short circuit does not occur, and a so-called cabinet baffle plate or frame is used. Can also work.

  The speaker frame 210 includes a second conductive member 232 having one end connected to the network component 400 and the other end connected to one of a pair of electric wires for supplying an electric signal, and one end connected to the voice coil and the like. A third conductive member 233 whose end is connected to the other end of the electric wire is also integrally formed. For this reason, the lead wire of the voice coil and the pair of terminals of the network component 400 are appropriately connected to the first conductive member 231, the second conductive member 232, and the third conductive member 233, so that the speaker unit 300 A series circuit of the voice coil and the network component 400 is configured, and assembly workability can be further improved.

  Then, the speaker frame 210 is integrally formed by insert molding the first conductive member 231, the second conductive member 232, and the third conductive member 233. Therefore, the first conductive member 231, the second conductive member 232, and the third conductive member facing the predetermined positions where the lead wire of the voice coil and the pair of terminals of the network component 400 are insert-molded and positioned. It is only necessary to connect to the H.233, and the assembly workability can be further improved, and the speaker frame 210 having the configuration for holding the speaker unit 300 and the network component 400 and the configuration for electrical connection can be easily formed integrally. .

Insert-molded to face. For this reason, it can connect easily, without producing inconveniences, such as a lead wire of a voice coil, and a terminal of network part 400 short-circuiting with other parts.

  In particular, insert molding is performed so that the first conductive member 231, the second conductive member 232, and the third conductive member 233 are in predetermined positions as both ends facing the surfaces. That is, in the first conductive member 231, the first lead wire connecting portion 231B on one end side is substantially opposed to the insertion hole 215A of the speaker holding portion 215, and the first terminal connecting portion 231C on the other end side is the partition wall portion 216C. Insert molding is performed so as to face the component holding portion 216 on one side. The second conductive member 232 has a second terminal connection portion 232C on the other end side in a state where the second terminal connection portion 232B on one end side faces the component holding portion 216 on the other surface side of the partition wall portion 216C. Is insert-molded so as to face substantially toward the closing plate 217A. Further, the third conductive member 233 is configured such that the third lead wire connecting portion 233B on one end side is located on the opposite side in the radial direction of the speaker holding portion 215 with respect to the first lead wire connecting portion 231B. The third electric wire connection portion 233C is insert-molded so as to substantially face the insertion hole 215A and substantially face the closing plate 217A. For this reason, the connection part is located at a position where the lead wire of the voice coil in the speaker unit 300 held by the speaker holding unit 215 and the pair of terminals of the network component 400 held by the component holding unit 216 are close to each other. Thus, assembly manufacturability can be easily improved.

  The speaker frame 210 has a speaker hole 213 in which the speaker unit 300 is disposed, and a mounting flange portion of the diaphragm 310 constituting the speaker unit 300 in a mounting step portion 213A provided at the opening edge of the speaker hole 213. 312 is attached, and the speaker unit 300 is assembled by disposing the magnetic circuit portion on the speaker holding portion 215. For this reason, the speaker frame 210 functions as a so-called frame of the speaker unit 300 to which the speaker unit 300 is attached, and also functions as a so-called frame of the speaker unit 300, so that the configuration can be simplified by sharing components.

  Further, the speaker frame 210 is integrally formed so that the speaker holding portion 215, the component holding portion 216, and both ends of the conductive members 231 to 233 face the back side of the plate portion 211.
