Description

Microphone
Technical Field
The invention belongs to the field of microphones, and particularly relates to a multifunctional microphone.

The microphone is also called as microphone, an electroacoustic equipment, belonging to microphone, which is a transducer for sound-electricity conversion, and applies sound wave to electroacoustic element to produce voltage, then converts it into electric energy. The microphone is used in various public address equipment.
Microphones are generally classified in the way they convert energy. Here we also classify microphones into moving coil microphones and capacitive microphones according to the most common classification of microphones in recording studios.
Moving coil microphones are microphones in which a conductor moving in a magnetic field generates an electrical signal. The vibrating diaphragm drives the coil to vibrate, so that the coil in the magnetic field generates induced current. The method is characterized in that: the structure is firm, the performance is stable, the durability is good, and the price is low; the frequency characteristic is good, and the amplitude-frequency characteristic curve in the frequency range of 50-15000Hz is flat; the directivity is good; the direct-current working voltage is not needed, the use is simple and convenient, and the noise is low.
The diaphragm of a microphone such as a condenser microphone is an electrode of the condenser, and when the diaphragm vibrates, the distance between the diaphragm and the fixed back plate changes, thereby generating a variable capacitance, which generates a signal voltage together with a preamplifier carried by the microphone itself. The method is characterized in that: the frequency characteristic is good, and the amplitude-frequency characteristic curve is flat in an audio frequency range, which is superior to that of a moving coil microphone; no directivity; the sensitivity is high, the noise is small, and the softness is good; the output signal level is larger, the distortion is small, the transient response performance is good, and the advantage that the moving coil microphone cannot achieve is achieved; the working characteristics are not stable enough, the sensitivity of the low frequency band is reduced along with the increase of the service time, the service life is short, and the use is inconvenient because a direct current power supply is needed during the working.
At present, a connecting circuit is mostly exposed outside a microphone, the microphone is held to move when the microphone is used, the moving distance of the microphone is controlled by adjusting the length of an external circuit, the moving range of the whole microphone is determined, some microphones are fixed on a table top when the microphone is used, for example, the microphone in a classroom is fixed on a teaching table, when a teacher writes on a blackboard, the microphone cannot be directly taken up, so that the teacher cannot perform real-time teaching through the microphone when writing, and the using effect of the microphone is poor.
