• What is Receiver?

  A receiver is an electro-acoustic converter device mainly used to convert electrical signals into speech signals. It plays a crucial role in telephones, achieving this function through different energy conversion principles such as electromagnetic, dynamic, and piezoelectric . The characteristic indicators of a receiver mainly include impedance, sensitivity, and frequency response. Sensitivity represents the receiver's ability to convert electrical signals into speech signals, while frequency response reflects the changes in receiver sensitivity at different frequency signal inputs.

• The working principle of the receiver

  1. Magnets generate a magnetic field

  When external current passes through the coil, a magnetic field is generated inside the wire circle. This magnetic field will interact with the magnet, causing the vibrating plate to vibrate.

  
  

  2. Vibration plate displacement occurs

  Due to the generation of a magnetic field inside the coil, a force is applied to the vibrating plate. This force will cause displacement of the vibrating plate. And push it forward.

  
  

  3. The coil generates an electric field
  

  When the vibrating plate approaches the diaphragm, it will generate a motion on the coil. This movement will cause an electric field to be generated domestically, thereby disrupting telecommunications.

  
  

  4. The diaphragm converts mechanical vibration into sound signals
  

  When mechanical vibration reaches the diaphragm, the diaphragm applies a reaction force and converts it into a sound signal. This sound signal can be transmitted

  Classification of receivers

  According to different working principles and structural requirements, receivers can be divided into various types such as magnetic receivers, capacitive receivers, and piezoelectric receivers

  Type. Among them, magnetic receivers are the most common type, mainly used in fields such as telephones, radios, and speakers.
