What is a dynamic microphone

Dynamic Microphone-Dynamic Microphone
Moving coil is an important technology for sound/electric conversion in the 20th century. Now most headphones and speakers (the woofer) also use this method. It is very similar to ribbon microphones: low sensitivity, slow transients, and insufficient high-frequency pickup. , However, the diaphragm is more durable than aluminum tape. It is mainly used in KTV and live performances (to avoid "howling"). In the recording studio, it is mainly responsible for "physical work", especially the recording of drums.

Dynamic microphones are currently the cheaper type of professional microphones. The "industry standards" include Shure SM58 vocal dynamic microphones and SM57 instrumental microphones (sound tough), both of which are about 100 US dollars. If you add 50 US dollars, you can basically buy them. To the dynamic microphone with higher sensitivity and widest frequency response, such as Shure Beta 58 or JZ HH1.

Sound principle of dynamic microphone

As the name says, a "moving coil" is an active coil, and sound waves cause the diaphragm to drive the coil to cut off the magnetic field, thereby generating an electric current. Dynamic and aluminum ribbon microphones have similar characteristics, low sensitivity, slow transients, insufficient high frequency, low frequencies are usually inferior to aluminum ribbon, but the diaphragm is very resistant to pressure, the microphone is durable and anti-drop, except for live sound reinforcement (low sensitivity can be Avoid howling), also used to be responsible for the "physical work" of the recording studio, especially the recording of the drum kit.
