Product description

  • This 40mm speaker headphone driver comes with an internal magnet that can convert full frequency, treble, mid range, and low range sounds great.
  • The speaker has both positive and negative electrodes. The positive electrode is marked in red, and the unmarked point is the negative electrode. Please do not solder for more than three seconds. Welding time is too long. It is easy to burn out the voice coil leads or directly burn out the circuit board, causing the speaker to short-circuit and become silent.
  • Package includes 2 pieces replacement speakers.
