Bluetooth Microphone Circuit Board Assembly
This condenser microphone uses a 3722TX sensor. When two extremely thin metal films are vibrated by sound pressure, they change the capacitance on the capacitor metal film, thereby generating current, and the sound signal is directly converted into an electrical signal. It needs polarization pressure to be used. We choose to use 48V phantom power to supply power to the amplifier. After the amplifier is amplified multiple times, the electrical signal is converted into a sound signal for output. This kind of condenser microphone has high sensitivity (-36～-50dB), high directivity, signal-to-noise ratio is greater than 66dB, will not affect the material due to the high temperature of the tin furnace, SMT can be mass-produced, and the product has good stability. Applicable occasions: Film and television recording studios and recording studios (quiet spaces), suitable for crowds, professional singers, people who record songs/audio books in high sound quality, and reproduce the original sound. Some people who have a thicker and deep voice are very suitable, which can balance your tone.

Advantage:
1. Light weight, small size, fast response characteristics, extremely light and thin metal material vibrating membrane, the vibrating membrane does not have any load,
2. Wide frequency response, high sensitivity (ultra-low frequency below 10Hz, treble 10KHz, human ear audible frequency response range is 20Hz～20kHz), the vibrating membrane is made of extremely light and thin metal material film,
3. The product has good stability and can be mass-produced by SMT;
Disadvantages:
1. The structure is complex, the cost is more expensive than the moving coil, and it needs power supply to work.
2. The sound film is fragile, easy to be damp and afraid of falling, and difficult to store. The precious ones are stored in a vacuum moisture-proof box.
