Trend common with my brother and his friends

post #1 of 10
Thread Starter 

My brother is 14 and his friends all have dented the middle of their earbuds inwards, so there's like a small inwards bump in the middle of their earbuds
They say it improves bass quantity

Any validity to this? Or are they just wrecking their earbuds

if it changes the shape of the driver it may very well change the sound, but probably for the worse.

 

personally i say they are idiots for doing it.

I thought you meant they bent their ears for a second lol. Denting a driver changes the frequency response. You may not be able to hear it but it will never be the same.

Part fad, part placebo I'll say.

Don't call me stupid.

That sounds like reverse engineering to me.

Actually, There may well be some logic to this. Sound waves propagate in a radial pattern, and where they collide they either interfere constructively or destructively, creating a single "perceived" wave made up of the components of all the individual waves. Now, by creating a concave indent in the surface of the diaphragm, there is a higher density of waves per surface area in the center, where they are colliding and focusing into a more coherent wave. Now, this "single" (not really single, but this is a simplification) wave will have some unique properties. Yes, it will be distorted an amount, because there is now cancellation between various frequencies interacting, but, depending on the size of this indent, there will be a certain frequency or frequencies at which the sound waves from the surface sum together and create a wave of greater magnitude via constructive interference. Given that the width (and therefore depth) of the indent is macroscopic (made by a probing hand or pen or what not), it would likely create a boost in the bass region of the frequency response of the diaphragm. Also, by adding non-linearity to the surface, the diaphragm would become stiffer, and thus  might also aid in bass reproduction.

 

 

Now sure, this is going to create distortion, and frequencies near the frequencies being amplified are going to be canceled (this is what causes bass "bloom" and "bleeding" into the lower mid frequency spectrum), but in the end, it certainly would reason that this gives the earbuds more bass.

Of course, thats how sound chambers work, and those cardboard phone 'speaker amplifiers' that wrap around the speaker outlet.

Question is, whether it sounds better.
