- #2 [hahaha1234], 20-09-21 21:24其實我已經加左4粒木釘(由於有個位係2塊雲石之間,唔平,所以zip左張memo紙墊高佢)…
- #3 [Krell], 20-09-21 21:37死症呢。

- #4 [lkp2109], 20-09-21 21:55我亦遇過類似問題,在釘墊底加水松貼便解決了。
- #5 [hahaha1234], 20-09-21 22:11呢種薄既水松係邊度買既?
係只要放係低左既一面,定要4粒釘都有既? - #6 [lkp2109], 20-09-22 06:28一般家居用品店買的,如無水松或買橡膠貼試試吧,所有釘墊都要加。
- #7 [diwily], 20-09-22 11:44My post several years ago :
Indeed, placing speakers on top of cabinet surely will not produce good sound. When the
speakers are working, they transmit the vibration to the thin cabinet top, the latter will
vibrate as well & muddle the sound. The speakers will also "jump" along with the
vibration. If you cannot use speaker stands, there is one inexpensive way to damp the
vibration.
Buy a piece of SANRUBBER from Hings Group. See the link below. You can browse to
search for exact location of their shops. There are a few at Reclamation Street between
Mongkok and one at Thompson Road, next to Wanchai MTR.
Address of their shops : "http://www.hings.hk/net_hk.aspx"
Enter the link below, the product on the right-most side is Sanrubber,
9mm thick, 445 x 910 mm.
"http://www.hings.hk/productMidSize.aspx?p=34-SOUNDPROOF-O.jpg"
Price was $300 several years ago. It is made for use under the wooden floor of dancing schools/halls to damp vibration & sound transmission.
Several friends with similar situation as yours have tried it & found big improvement.
Just use cutter to trim to size of speaker base [or a little larger] & place it on cabinet top.
Also, you have to place on top of the Sanrubber a pc of black granite slab 黑麻石
[不是雲石] minimum 20mm thick, in size same as the cut Sanrubber.
This is available from "Marble/building material" shops at Portland Street, MK or
Lockhart Road, Wanchai. You can place the speakers on the granite slab with or
without spikes & discs. Just try which way you find the sound to your taste. I am using
the same under my cdp, along with TAOC 46 PIN spikes & discs. I can knock under the
rack when playing cd & it is not affected by any vibration.
Granite slab = 花岗岩板, also called麻石. Black color has the highest density & least
vibration.
Highly recommend that you try this treatment under the speakers & also the cdp.
It costs just a few hundred $ but improvement is big.
Can also try the same under the dvd/blue ray player for better picture & sound quality.
連氏興業未必每間門市店都有 Sanrubber 防震胶, 建議先致电查詢才去.

- #9 [spyder], 20-09-22 16:17用海綿磚, 將成個喇叭long 起。
釘脚係避唔到震,只會將振動頻率改變。

Bearing 好處是上震傳不到下丶下震傳不到上丶像double tiptoe
有些名牌喇叭用向上及向下釘

最後修改時間: 2020-09-22 18:54:05 - #12 [Yourcousin], 20-09-22 23:13要整個情況去睇。
個櫃本身唔掂,唔係俾音響用,點攪都解決唔到基本問題。雲石面,加釘,加甚麽甚麽,可能有少少改善,但...
如果對音響有一定要求, 換櫃是正途,乜不一定要換貴嘢.... - #13 [spyder], 20-09-26 14:43換櫃都係只會改變共振頻率,溝埋d声啱聽就叫好声咗,反之亦然。
喇叭震動空氣,我們先會聽到音響,附帶既係: 櫃,椅,器材,牆身都陪我哋 "聽" 緊音響。
任何墊底工具都避不了震,不如試下將喇叭吊响空中,這樣個櫃震動最少,沒成本,一試無妨啊。
(不要信什麼 "馬步不穩" 便不好声之類的肺腑之言,因為他賣腳架的) - #14 [DYreal], 20-09-26 21:06每個密封嘅空間都會有一個特定嘅諧振頻率,你個櫃分成多個空格自然會產生咗好多唔同嘅係諧震頻率(裏面嘅物件亦都影響咗諧震頻率)。就算你解決到喇叭震盪傳落去個櫃呢個問題,衹要有一定音量和一定低頻,櫃便會產生諧震最終就傳返上喇叭令到喇叭震盪。所以點解音響櫃係冇四邊封住嘅圍板,噉樣先可以避免咗一個密閉空間出現嘅諧振頻率。
如果唔想搞個櫃,響屋企又話得事嘅話,最簡單方法就係在後牆裝過非常堅固嘅L形架,千萬不要用一條條角鐵上螺絲整個L形架咁樣一定死硬(某程度上嚟講真係變相是吊高咗個喇叭),再在架上面做返之前嘅避震設施,我諗應該有唔錯嘅效果。
但係師兄會唔會為咗音質去到咁盡呢。

如成功丶改用數層foam 板丶可介到好看丶板穩定過波波紙 - #16 [hahaha1234], 20-11-26 09:56我係呢段時間裏面試左好多墊材,試到最後有個師兄介紹一個錄音室用既海棉,效果真係非常好,對喇叭真係好似升級左好多陪,我之前都睇少左佢,冇諗過佢咁掂,各位師兄真係可以試吓~
- #17 [hahaha1234], 20-11-26 10:07個盒冇影到⋯⋯
- #18 [hahayanyan], 20-11-26 10:12No harm to understand that vibration, test it before and after a song is played.. Etc.. Then.. U may have some more idea on how to deal with it
This is one of the better apps
https://play.google.com/store/apps/details?id=com.kroeber.vibration_analysis
when we try any kind of supporting feet or adding something (such as a piece of wood, sand bags..etc)
by using this simple apps, u may understand is it just shift but not take away any the frequency of the vibration but lower amplitude etc
or there are things can take away and also reduce the total energy of the vibration
Your 櫃 may also be singing like a speaker cabinet too , if yes, then wish it has a nice tone
etc..
not accurate, but good enough for BEfore and After type of Finding
have fun
haha
