上らない欠点があつた。 Conventionally, the main parts of a micro speaker, headphone, microphone, etc., as shown in FIG. The annular bottom surface of the diaphragm 6 was attached to the upper end of the voice coil 1, and the outer periphery of the diaphragm 6 was attached to the outer periphery of a frame 7 attached to the plate 3. In this case, there is an ineffective portion 2 above the voice coil 1 to which little magnetic flux is applied, and although the impedance increases, there is a drawback that the efficiency of the micro speaker etc. cannot be improved.
本考案は上記欠点を除く為に考案されたもの

イスコイルである。 The present invention was devised to eliminate the above-mentioned drawbacks, and if the embodiment shown in the drawings is explained, the second embodiment will be described.
As shown in the figure, a main body 1 is formed by winding a conductive wire into a cylindrical shape, and the ineffective part 2 of the main body 1 near the adhesive part of the diaphragm 6 is welded with chemicals or mechanically welded with solder 8, etc. to form a winding wire. This is an electrically shorted bobbinless voice coil.
本考案は上記のような構造になつているので、
従来よりインピーダンスが減少し、スピーカ等の
能率が向上するもので、簡単な方法でマイクロス
