There is no difference between a microphone and a microphone. They belong to the same type of product, they are just two different names. A microphone, also known as a microphone, is an electroacoustic equipment, a microphone, and a transducer for acoustic-to-electrical conversion. It uses sound waves to act on electroacoustic components to generate voltage, and then converts it into electrical energy. Used in various loudspeaker equipment.
On March 4, 1877, Emil Berliner invented the microphone, which is what we call a microphone. Microphone in English is microphone (transliteration), and its English abbreviation is: MIC.
Microphone (microphone) is a kind of electroacoustic equipment. It is a microphone and a transducer for acoustic-electric conversion. It uses sound waves to act on electro-acoustic components to generate voltage, and then converts it into electrical energy. Used in various loudspeaker equipment. There are many types of microphones and simple circuits.
Microphones can be divided into two types: electric microphones and condenser microphones according to their energy conversion principles. Among them, the electric type can be subdivided into dynamic microphones and aluminum ribbon microphones.
Common commercial microphone types include condenser microphones, crystal microphones, carbon microphones and dynamic microphones.
There are two energy sources commonly used in condenser microphones: DC bias power supply and electret film. Both condenser microphones and crystal microphones convert sound energy into electrical energy, producing a changing electric field.
The carbon microphone uses a DC voltage source to change its resistance through sound vibration, thereby converting the acoustic signal into an electrical signal. Condenser, crystal, and carbon microphones all produce a voltage signal proportional to the displacement of the sensitive membrane, while dynamic microphones produce a voltage signal proportional to the vibration rate of the sensitive membrane. The dynamic microphone uses permanent magnets as the energy source and converts sound energy into electrical energy based on the inductive effect
