What are the main structures of Shenzhen Mito manufacturers? Microphone is an energy converter that converts sound signals into electrical signals. It is just the opposite of horn. Microphone can be divided into grid pole welding type, grid crimping type, pole ring connection type, etc. Take omnidirectional mic, diaphragm pole ring connection as an example:

1. Dust screen:
Protect the microphone head, prevent dust from falling on the diaphragm, prevent external objects from piercing the diaphragm, and have a short-term waterproof effect.
2. Enclosure:
The support of the whole microphone and other parts are encapsulated in the shell, which is the grounding point of the microphone and can also play the role of electromagnetic shielding.
3. Diaphragm:
It is a main part of acoustic electric conversion. It is a tight Teflon plastic film adhered to a thin metal ring. The contact side between the film and the metal ring is plated with a very thin metal layer. The film can be charged. It is also an electrode plate forming a variable capacitor, and it is a vibrating electrode plate.
4. Gasket:
The distance between the two polar plates of the supporting capacitor leaves a gap to provide a space for the vibration of the diaphragm, so as to change the electric capacity.
5. Back plate:
The other electrode of the capacitor is connected to the G (gate) electrode of the FET (field effect transistor).
6. Copper ring:
Connect the electrode plate to the G (gate) electrode of FET (field effect transistor) and play a supporting role.
7. Cavity:
Fix the plate and ring to prevent the plate and ring from short circuiting to the housing (s (source) and G (gate) of FET).
8. PCB assembly:
Equipped with FET, capacitor and other devices, it also plays the role of fixing other parts.
9. Pin: some microphones have a pin (PIN) on the PCB, which can be welded with other PCBs through the pin. In addition, the front pole type and back pole type are also slightly different in structure.
