Hello everyone,
It's been a long time coming back with the
video
 how to increase bass for speakers,
Improve sound for better listening speakers.
Especially applicable to weak magnet speakers.
The reason is that I have posted the video
to prove that it is working really or not
And for you to determine when to add magnets
in any direction.
It's been a long time since my creation.
But there are many opposite opinions.
And some of you do not believe it can increase
the speaker's power to give the speaker better
bass,
So today I decided to prove this,
Now I will decide to remove the original BMB
speaker to see how it looks,
And when I remove the BMB magnet
the two magnets have opposite directions
2 magnets It pushes each other up.
It's not the same direction,
 why so
Later I will explain to you
Because I'm just like you
First, I will mark A and B on the magnet
Some people say that the coil is outside the
magnet, so it does not work
So I will experiment with the speaker windings
First I would measure the metal rod behind
It has a thickness of 8mm
This is quite thick
Now I will put the coil on the outside of
the magnet
It is even farther away than the distance
I have measured,
To see if it works or not,
I will power the coil with 12Vdc source,
and I will not reverse the power supply,
If I reversed the power source it would turn
into a thrust,
And when I reversed the power back, it would
turn into a suction power
If I leave the coil outside the magnetic field,
its coil will not move.
Here I will not reverse the power supply for
the whole trial period,
So it worked,
, and this is the downward force
, it still worked, it was sucked down
 Seeing clearly,
and now I will reverse the magnet,
When I reverse the magnet, it turns into a
thrust.
And when I put the coil close to the inside
of the speaker,
Of course, its thrust is stronger.
However I will try it located on the outside
of the magnet,
Whether it works or not,
So it still works,
The magnetic field of the magnet still has
an effect on the coil,
If there is no magnetic field, the coil will
not move,
So its magnetic field is very wide
Now I will get another CD
still works
Even though I cover it with aluminum
So it is quite distant
And it is very difficult to stop it
Can not say They use more magnets to avoid
interference to televisions
if they want to shield the noise
They will use cold iron wrapped
around
Like a computer speaker you just saw
I have marked all
the B surface
This means that the faces of the B magnets
are the same
It means that the same direction pushes the
coil in one direction,
So when you add magnets to the same direction
B
it will push the coil together
this is merit
This makes the magnet stronger
Of course two magnets will push the coil better
than a magnet
So the final conclusion is
add magnet along the suction side
You should add magnets to each other
thus increasing the strength of the magnet,
and increase the power of the speakers
If you stick in the direction of repulsion
it will not increase the strength of the magnet,
Unless your bottom magnet is very good and
strong,
So why does BMB add magnets in the opposite
direction,
BMB has added magnets in the direction of
repulsion,
means a suction and a push,
reason:
The rear metal of the speaker is quite thick,
This also reduced some of the magnetic attraction,
The second is the bottom magnet, the main
magnet and strong enough,
And if it
is a genuine magnet
so
Add a second magnet to keep the coil
This causes the coil to be retained,
Makes the bass sound stronger and stronger
The vibration of the coil is limited
coils are less likely to move
for reasons
Some of the speakers that are designed on
the front of the speaker are hard paper
to make the drum stronger and stronger.
They designed the hard surface to better hold
the coils
So they add a magnet to help keep the coil,
So it also works for better bass
Applicable to amplifiers with good power
However
with us
I want the speaker stronger when the magnet
is weak
Then you have to attach two magnets to attract
each other
If your main magnet is strong, you will attach
two magnets in the opposite direction
