Abstract

PURPOSE:To secure the satisfactory adhesiveness without weakening a magnetic field, by coating thin and evenly an adhesive by means of a roller. CONSTITUTION:An adhesive 3 is coated to the circumference at the bottom of a pole yoke 1, and the a roller 6 is turned to extend the adhesive 3. A magnet 5 is press-fixed on the adhesive 3. Thus the yoke 1 is adhered with the magnet 5. In such a way, the adhesive 3 is extended evenly with the roller 6 to obtain the satisfactory adhesiveness with a small amount of adhesive. Furthermore the magnetic field within a gap of a magnetic circuit is never weakened since the adhesive layer is very thin.

Description

【発明の詳細な説明】 本発明は、スピーカの組立方法に関するものである。[Detailed description of the invention] The present invention relates to a method of assembling a speaker.

ク（１）の底部に塗布される。FIG. 1 shows the conventional method of applying adhesive when assembling a speaker. In the figure, a ball yoke (1) is placed on a rotating table (2), and as the rotating table (2) rotates, the pole yoke (1) also rotates. Glue (3) is applied to the bottom of said ball yoke (1) by a nozzle (4).

同様である。When assembling a speaker with this configuration, first,
The turntable (2) is rotated while extruding the adhesive (3) from the nozzle (4). Thereby, the adhesive (3) is applied to the bottom-periphery of the ball yoke (1). By crimping the magnet (5) on top of the pole yoke (
1) and magnet <5) are bonded. Magnet (5

グネット、トッププレート間の接着層が厚くなり、磁気
回路ギャップ内の磁界が弱くなるという欠点があった。In this assembly method, since the adhesive is applied and the magnets etc. are pressed onto the adhesive, a large amount of adhesive must be flowed, which causes the adhesive layer between the pole yoke, magnet, and top plate to deteriorate. It has the disadvantage that it becomes thicker and the magnetic field within the magnetic circuit gap becomes weaker.

また、接着剤が均一に塗布されないため接着力も不十分
であった。Furthermore, the adhesive force was insufficient because the adhesive was not applied uniformly.

を目的とするものである。The present invention was made in order to eliminate the above-mentioned drawbacks, and provides a speaker in which sufficient adhesive force can be obtained without weakening the magnetic field by applying adhesive thinly and uniformly with a roller. The purpose is to provide an assembly method.

The rotating shaft (7) of the roller (6) is fixed (the fixed part is not shown), and rotates with the rotation of the ball yoke (1). The material of the roller (6) may be metal, rubber, resin, urethane foam, etc., and the shape may be not only conical as shown in the figure but also cylindrical.

Compared to the previous embodiment, one step is omitted, which reduces the assembly time. According to the speaker assembly method of the present invention, the adhesive applied by the roller is spread uniformly. In addition, strong adhesive strength can be obtained with a small amount. Furthermore, since the adhesive layer is thin, it does not weaken the magnetic field within the magnetic circuit gap.
