Condenser Microphone Vs dynamic microphone. It is on stage a
performance or a recording studio, you need good quality microphones to
be able to capture the sound as clearly as possible, with less noise and
inconvenience. The sound recording quality varies depending on the
nature of the microphone used. Therefore, it is essential that you know
what is the underlying technology that makes possible recording
microphones and what types of microphones are suitable for your
application.
Let us distinguish between the condenser and the
dynamic microphone according to the internal mechanism, making it
possible to check-in them. Then, we go to compare cost and differences
between the two types of microphones.
Differences in basic technology
Let
us begin to see the difference between microphone condenser and dynamic
microphone the principle used to convert the sound into an electrical
signal.
So, what is a condenser microphone? Condenser is a
synonym for "capacitor" and condenser mics have a mounted condenser in,
which makes it possible to the sound recording. When sound is received
by the condenser microphone, it makes a small diaphragm vibrates, which
is actually one of the two plates of a capacitor. A constant coulomb
charge is maintained on two capacitor plates, using an external power
source.
The vibrations cause the diaphragm to oscillate, the
distance between the capacitor plates varies, resulting in a variation
of capacity, which in turn causes by varying the voltage. This variable
voltage is converted into a signal that is registered to store sound or
retransmit them to a speaker
Difference in Power
A
point of difference between condenser and dynamic microphone is power
requirements. Condenser microphones need to be powered externally, but
the dynamic microphones do not need them. Condenser microphones are
known to be more sensitive to sounds, but their small diaphragms make
delicate instruments. Although low sensitivity, dynamic MICS are much
more robust compared to their counterparts at base of capacitors.
Physical differences
Differences condenser microphone and dynamic microphones, In the visible will indeed look be clearly distinguished from the physical form and the great mic. Condenser mic looks much smaller, simple and lightweight, although there is some type of condenser which is also rather large shape like a gooseneck microphone used for the reception or information desk, while the dynamic mic looks great and it's a bit heavy.
Technical differences
Condenser microphones are generally circular in shape with a small size where in microphone that there are two very thin plate as the diaphragm, serves as the recipient of any vibrations coming from outside or due to differences in air pressure on every second that produce vibrations.
In condenser microphones, vibration captured by a plate. Therefore this type microphone can respond much noise or high frequency. The principle works; condenser microphone will not work if not given voltage. In contrast to the dynamic microphone can work immediately when plugged into a mic preamp. In condenser there are positive and negative polarity means during setup mic should not be reversed and should receive supply voltage direct current, although it requires a supply voltage. Condenser microphones sufficiently supplied with a small voltage.
Condenser mic can not be used directly, there should be an additional opamp circuit for condenser mics should be supplied voltage can only change sound into electromagnetic vibrations.
Dynamic mic
Mic dynamic or dynamic microphone, large shape, in which there are coils and magnets, while for the diaphragm is made of thin plastic material that will move the coil in it, is in principle similar to the
speaker if the speaker accepts voltage and convert it into sound vibration and impedance 4.8 - 16 Ohm. whereas the Dynamic mic impedance of 600 Ohm transform sound vibrations into electrical voltage which is then transmitted and amplified by the mic preamp.
Dynamic mic requires strong vibrations to drive the coil, contained in magnet field to produce the amount of voltage, so the dynamic microphone is less sensitive than the condenser because it requires a strong vibration from the outside, therefore the sound is likely to medium bass. And usually the distance between the mic close to the sound source to produce the perfect sound.
That's some difference between the condenser microphone with a dynamic microphone that can be seen and felt. Hopefully this short article helpful, thank you.
