拾音棒

拾音棒 (shí yīn bàng), commonly known as a microphone, is a device that converts sound waves into electrical signals. These signals can then be amplified, recorded, or transmitted.

Material:

• Diaphragm: Typically made of materials like Mylar (polyester film), metal, or ceramic, chosen for their sensitivity and responsiveness to sound vibrations.
• Transducer: The core component converting mechanical energy to electrical signals. Common types include:
  • Dynamic: Utilizes a moving coil suspended in a magnetic field. Robust and suitable for high-volume sources.
  • Condenser: Employs a capacitor that varies capacitance with sound pressure. Offers high sensitivity and wider frequency response. Requires external power (phantom power or batteries).
  • Electret Condenser: A type of condenser microphone with a permanently charged diaphragm, simplifying power requirements.
• Housing: Often constructed from metal (steel, aluminum) or durable plastic to protect internal components and reduce noise interference.
• Cable/Connector: Typically XLR, USB, or 3.5mm connectors for signal transmission.

Purpose:

The primary purpose of a microphone is to capture audio for various applications.

Function:

Sound waves cause the diaphragm to vibrate. This vibration is then converted into an electrical signal by the transducer. The strength of the signal corresponds to the intensity of the sound.

Usage Scenarios:

• Recording: Studio recordings (vocals, instruments), field recordings, podcasting.
• Live Performance: Vocal amplification, instrument amplification, public address systems.
• Broadcasting: Radio, television, voiceovers.
• Communication: Telephony, video conferencing, gaming.
• Measurement: Sound level meters, acoustic analysis.

Common Types:

• Dynamic Microphones:
  • Shure SM58: Industry standard for live vocals. Rugged and reliable.
  • Sennheiser e609: Designed for guitar amplifiers.
• Condenser Microphones:
  • Neumann U87: Highly regarded for studio vocal recordings.
  • Rode NT-USB: Popular USB condenser microphone for podcasting and streaming.
• USB Microphones: Convenient for direct digital recording.
• Lavalier Microphones (Lapel Mics): Small microphones clipped to clothing for hands-free recording.
• Shotgun Microphones: Highly directional microphones used for capturing sound from a distance.
• Headset Microphones: Combines a microphone and headphones for communication and gaming.
• Ribbon Microphones: Uses a thin metal ribbon suspended in a magnetic field. Known for their warm, natural sound.
