る。2. Description of the Related Art In a cone speaker which has been widely used in the past, as is well known, a diaphragm has an axisymmetric shape, and a voice coil is coaxially attached to the tip mounting tip at the center of the center axis. , It has a structure that drives this center. In such a structure where the busbar has a uniform length, the vibration plate bends due to vibration, resulting in a split resonance state at a natural frequency, and at this resonance frequency peaks and dips occur on the frequency characteristics and the transient characteristics deteriorate. Furthermore, there is a drawback that the shape of the diaphragm is distorted due to the bending of the diaphragm base body due to the unreasonable vibration, and the reproduced sound quality is deteriorated. In addition, since the center axis of the directional characteristic, that is, the center axis of the diaphragm coincides with the center axis of the mounting surface of the speaker in the axisymmetric speaker, the center axis of the directional characteristic is inclined with respect to the front center axis of the speaker. Requires an additional structure such as an acoustic lens in front of the speaker. To eliminate this drawback, there are eccentric cone loudspeakers in which the diaphragm is not coaxial with the drive point, ie the voice coil.

る。As shown in the structure of FIGS. 5 and 6, the above-described eccentric cone speaker has a vibration system in which a voice coil 12 is attached to the tip of an eccentric cone diaphragm 11 having a non-circular outer periphery, as well as a vibration system. Inside the non-circular frame 15 in which the magnetic circuit 14 is attached at a position deviated from the center, the voice coil 12 is inserted into the magnetic gap 14a of the magnetic circuit 14 in a vibrating manner, and the voice coil 12 is inserted through the edge 13. It is a supported structure. In the speaker having such a structure, since the distance from the driving point where the voice coil 12 is attached to each peripheral portion of the diaphragm 11 is not uniform, significant split resonance at the natural frequency does not occur.
It is possible to eliminate the above-mentioned peaks and dips on the frequency characteristic, deterioration of the transient characteristic, and distortion due to bending of the diaphragm substrate. Further, the central axis k of the directional characteristic is inclined in the major axis direction of the speaker. There is an advantage that can be made.

していた。The above-mentioned eccentric cone speaker removes a factor that deteriorates the characteristics due to the shape of the diaphragm 11 and keeps the sound quality of the speaker good. Due to the asymmetry of the shape of the diaphragm 11, a non-circular frame 15 having a shape corresponding to the shape is required, and the assembly process is extremely difficult in assembling and manufacturing the speaker, and the cost is high. That is, in the manufacturing process of the speaker, it has been customary to apply the adhesive and assemble the parts with the center of the magnetic circuit 14 as the reference position. Since the parts and their positions are eccentric, a special manufacturing facility is required, and there is a problem to be solved that the structure is extremely difficult to produce.

It is an object of the present invention to provide a speaker with excellent characteristics, which has been devised so that it can be produced by the equipment and production method.

However, since the top surface of the magnetic circuit is not parallel to the frame, it has a drawback that it is difficult to assemble the magnetic circuit in the center of the manufacturing process.
