the mechanical resonance.
This is a physical deformation of the capacitor walls which occurs as a result of the audio signal passing through the component – much like an electrostatic speaker.
This resonance is dependent on the size, shape, materials and manufacturing parameters of the capacitors.
The resonances always occurred between 5 and 25kHz
When charged, the capacitor plates are attracted to each other, forming a compressive force across the body of the capacitor. During discharge,
this force is released and the plates return to their resting position.
Since the force between the plates of a charged capacitor is always attractive, driving with a sine wave, like an audio signal, will produce a mechanical force at twice the driving frequency; an example of this ‘frequency doubling’ effect is shown below.
This raises the issue of the capacitor being a possible source of intermodulation distortion products at double the frequency of any audio signals present.
只要有聲音就有震動,因為有空氣的存在,空間的大小決定了震動的影響,所以空間與喇叭是震動的因素,音樂廳裡的rpg與響板,吸音板及觀眾都是影響震動的一些因素甚至決定了rta,與語音清析度,相對的在視聽室中所有的東西對震動可以是正面的也有反面的
聲波在音響室主要有兩個角色,
一是空間來回的聲響,對應的是空間處理.
一是聲音造成的震動,對應的是震動處理.
兩者均是十分重要的課題.
HRS的抑震(墊)板很不錯!!
壓放在某些機箱殼的上方效果顯著!!:*:*:*
元件通電造成的震動 以及外在聲波激發機殼產生的震動都不難理解,
但說實話,
我一直搞不太懂為什麼這些震動會進入訊號鏈內呢?
究竟這些震動改變了什麼?
電 的純靜 震 的最少 在人的專業科技[工業]領域 是可作到,但工程浩大 經費~~~可想而知!所以說了也是白說 沒人願做:D
