ものではない。Distortion that has conventionally been considered a problem in speakers includes linear distortion, non-linear distortion, speaker shape,
The strain caused by the structure was To9, and countermeasures for these were considered, such as design and processing accuracy, improving the uniformity of the cone material, and reducing density. However, in addition to the nine distortions mentioned above, there are also problems such as bonding the voice coil and speaker cone with adhesive, speaker assembly such as press-fitting a press fit, assembly using adhesive for cabinets, and molding of parts such as ducts and equalizers. found that many mechanical distortions, such as those caused by assemblies, also have an important effect on sound distortion. At conventional speaker manufacturers @J, aging is removed from high-end speakers before they are shipped. However, this aging process is carried out at room temperature and is carried out on each speaker over the course of a day and night, so it is extremely time-consuming, and if used in anything other than high-end products, the cost would be high, and the number of parts would be too large to be practical. It is not possible to eliminate the distortion of sound caused by mechanical deformation as described above.

実用上好ましい。1. The present invention provides a method for manufacturing a speaker, which comprises annealing a speaker system or a speaker unit and/or a speaker cabinet after or before assembly. Annealing of the speaker system or speaker unit and/or speaker system is carried out at a temperature of about 45C to about 100C for an extended period of time. In this case, the speaker system or the like may be annealed as a whole after being assembled, or the parts may be annealed individually before being assembled. A well-balanced effect can be obtained by annealing the general ICId and system after the entire system has been assembled. Also, although it is possible to anneal at high temperatures (depending on the material of the part), when annealing parts or assemblies made of materials such as paper, it is recommended to anneal at extremely low temperatures or for shorter annealing times. It is common to do this by In particular, speaker units and the like are passed through a hot air oven to dry and harden the adhesive during assembly, but this naturally cannot eliminate the distortion caused by mechanical deformation caused by the curing of the adhesive. The annealing process in the present invention is performed after the adhesive is cured in order to remove the strain caused by the adhesive thus cured. Furthermore, this annealing step can be carried out by simply placing the speaker unit or cabinet in a predetermined position in a space where the temperature is maintained at about 45C to about 100C for a certain period of time. Therefore, in the manufacturing process according to the present invention, the annealing process can be carried out without the need for the labor-intensive kneading process that has been carried out for conventional high-end products. Practically preferred.
以下、本発明を実施例により説明する。The present invention will be explained below with reference to Examples.
