まずは今月の営業日に関するお知らせです。
以前にご紹介いたしました「ダ〇ソー300円スピーカー」
ですが、価格に見合わない高い性能は「DHD-04」
製作時にも思い知りました。
しかし低音と高音に不自然な盛り上がりがあり、
いわゆる「ドンシャリ」といった音が特徴でした。
これは長時間聞いていると、何となく疲れる音です。
ある日･･･
「片側2個仕様にすることで欠点が解消された」
という記事を目にしました。
「製作意欲」という悪い癖に火が灯りました･･･。
スピーカーの「箱」について大雑把に解説しますと。
今回は上下で構造を変えた変形BLHである
「対称ホーン型」です。
（対称ホーンはyoutuberのKen＆Marieさんが考案したもので、
前半部分は音道を絞り後半で広げる構造のスピーカーBOXです）
今回も安価で加工のしやすい桐材を使います。
桐は密度が低く「共振」が起こりやすいので上半分は
強度UPを意識しました。
このスピーカーは取り付ける際の「ノリシロ」にあたる
部分が1㎜以下で密閉性に不安があるため、
厚紙でスペーサーを作りました。
見栄えもありますのでスピーカフレームと一緒に
艶消し黒を塗りました。
組み立ててから気づいたのですが、
吸音材を入れ忘れました･･･。
後で何とかします。
じつわ悩みごとがあります。
それは2個のスピーカーの接続についてです。
音質を考慮するなら「並列接続」が常識なのですが、
このスピーカーのインピーダンスは6Ωです。
使用するアンプの許容インピーダンスは
4Ω～16Ωとなっています。
結論は･･･先延ばしすることにします。
次回は最終仕上げと試聴を予定しております♪
