【００１４】[0014]
この考案に係るスピーカ振動板のエッジの実施例を図１乃至図３に基づいて説 明する。図１はスピーカユニットの断面図、図２はスピーカ振動板エッジの斜視 図、図３はスピーカ特性を示すた特性図である。 Examples of the edge of the speaker diaphragm according to this invention will be explained based on FIGS. 1 to 3. I will clarify.

Characteristic curves 12 and 13 show the impedance characteristics of the speaker. It is a sexual curve.
【００１６】 スピーカ振動板２をスピーカユニットの中心に保持するエッジ１は、図２に示 すように金型で加熱成型してロール又はラウンド形状部1aを形成し、フレーム３ に取り付けられる。[0016] The edge 1 that holds the speaker diaphragm 2 at the center of the speaker unit is shown in Figure 2. The frame 3 is heated and molded in a mold to form a roll or round shaped part 1a. can be attached to.
【００１７】 このエッジ１は、例えばナイロンやポリエステル、レーヨン等を約５ミクロン 程度の高分子微細繊維とした不織布状の素材であり、例えば東レ・エクセーヌの スエード調の人工皮革材料で形成したものであり、加熱成型はポリエステル・フ ィルム成型の温度条件と同じ略120 度で実施することができる。[0017] This edge 1 is made of nylon, polyester, rayon, etc. with a thickness of about 5 microns. It is a non-woven material made of polymer fine fibers of about It is made of suede-like artificial leather material, and heat molded with polyester film. It can be carried out at approximately 120 degrees Celsius, which is the same temperature condition as film molding.
【００１８】 この様にして加熱成型して形成したスエード調の人工皮革材料のエッジ１は比 重が0.27とウレタン・フォームに次いで軽量であり、しかも、高分子微細繊維の 集合体であるため耐環境性にも優れた特性を有している。また、エッジ１の繊維 間のずれ効果により振動を熱に変換するため共振しにくい特性がある。[0018] Edge 1 of the suede-like artificial leather material formed by heat molding in this way is comparable to With a weight of 0.27, it is the second lightest after urethane foam, and is made of fine polymer fibers. Since it is an aggregate, it also has excellent environmental resistance. Also, the fiber of edge 1 It has the characteristic of being difficult to resonate because it converts vibration into heat due to the gap between the two.
【００１９】 また、上記エッジ１を形成する凹凸金型の一方にシリコン樹脂を塗布し加熱成 型することにより、エッジ１表面の防水処理をすることができ防水効果を高める ことができる。[0019] In addition, silicone resin is applied to one side of the uneven mold that forms the edge 1 and heat-formed. By molding, the surface of edge 1 can be waterproofed, increasing the waterproofing effect. be able to.

【００２１】 図３において、音圧レベル特性10は本考案のスピーカユニットの特性曲線であ り、従来のスピーカユニットの音圧レベル特性11に対してエッジ１が軽量化され ているため音響出力音圧レベルを高くすることが可能である。[0021] In Figure 3, sound pressure level characteristic 10 is the characteristic curve of the speaker unit of the present invention. Edge 1 is lighter compared to the sound pressure level characteristics 11 of conventional speaker units. Therefore, it is possible to increase the acoustic output sound pressure level.
【００２２】 また、本考案のインピーダンス特性12と従来のインピーダンス特性13とを比較 しても分かるように、最低共振周波数fo=47Hz （従来の最低共振周波数fo=44Hz) と高くなり、最低共振周波数foの共振鋭度Qo=0.39 （従来の共振鋭度Qo=0.34)、 又機械共振鋭度Qm=7.9（従来の機械共振鋭度Qm=3.4) とインピーダンスを高くす ることができ、エッジ１の振動動作を動き易くし能率を高めることもでき、共振 による異常音が無くして音質改善を可能にすることができる。[0022] In addition, we compared the impedance characteristics 12 of this invention and the conventional impedance characteristics 13. As you can see, the lowest resonant frequency fo=47Hz (conventional lowest resonant frequency fo=44Hz) The resonance sharpness of the lowest resonance frequency fo is Qo=0.39 (conventional resonance sharpness Qo=0.34), In addition, mechanical resonance sharpness Qm = 7.9 (conventional mechanical resonance sharpness Qm = 3.4) and impedance are increased. It is possible to make the vibration movement of edge 1 easier to move and increase efficiency, and it is possible to reduce resonance. It is possible to improve sound quality by eliminating abnormal sounds caused by noise.
