い結果が生じる欠点があつた。 In general, speakers using a frustoconical diaphragm have a center pole 6,
A magnetic circuit is formed by the magnet 7 and the plate 8, a magnetic gap is formed between the center pole 6 and the plate 8, and the voice coil 1 is placed at the center of the magnetic gap.
The outer periphery of the damper 10 holding the damper 10 in the center hole is attached to the inner bottom of the frame 9 attached to the upper surface of the plate 8, and the voice coil 11 is attached hanging down to the center hole of the frusto-conical diaphragm 4. The outer periphery of the diaphragm 4 was attached to the outer periphery of the frame 9. In this case, when the speaker is operated, the abnormal resonance of the abdomen of the diaphragm causes severe distortion in the mid-to-high frequency range, as shown by the dotted line in the frequency characteristics of FIG. 3, resulting in unfavorable sound quality.
本考案は上記欠点を取除く為に考案されたもの

ーカ用防塵キヤツプである。 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, an annular adhesive part 2 is formed on the outer periphery of a spherical main body 1 to be attached to the abdomen of a frusto-conical diaphragm 4, and an annular protrusion 3 is formed on the adhesive part 2. It is a dustproof cap.

業上有益な考案である。 Since the dustproof cap of the present invention has the above-mentioned structure, it can further strengthen the abdomen of the diaphragm and cancel the occurrence of abnormal resonance, thereby reducing irregularities and improving sound quality, as shown in the solid line of frequency characteristics in Figure 3. This is an industrially useful invention because it produces favorable results and has a shape that can be mass-produced.
