Description

Technical Field

[0001] The utility model relates to the field of microphones, in particular to a detachable microphone. Background Art

[0002] Microphone, scientifically known as microphone, is translated from the English word microphone, also known as microphone or micro-phone. It is an energy conversion device that converts sound signals into electrical signals. Microphones can be classified according to their different working principles and structures, such as dynamic, capacitor, electret, etc. Most microphones are electret capacitor microphones, which work on the principle of using a polymer material vibration membrane with permanent charge isolation for sound conversion. In daily life, microphones are widely used in various scenarios, such as making calls, recording, meetings and speeches, performances and performances, recording videos, games, and speech recognition.

[0003] Conventional microphones are relatively simple. Usually, the main control circuit board is directly fixed to the inside of the microphone. The main control circuit board is fixed inside the microphone by bonding with adhesives, etc., or holes are punched on the main control circuit board and the main control circuit board is fixed inside the microphone with long screws. Both of these fixing methods can fix the main circuit board. After using it for a long time, the main circuit board will have problems such as short circuit between power lines, damage to internal capacitors, or unclear pronunciation of the microphone. Therefore, it is usually necessary to remove the outer casing to repair or replace the main control circuit board. However, after fixing the main circuit board with these two methods, it is not convenient to replace the main circuit board. The main circuit board is not convenient to replace and disassemble, and usually requires small screwdrivers and other tools to use, which is very troublesome. Moreover, the main circuit board is usually a thin plate with a small thickness and is easy to break. Once the microphone is shaken or dropped, the main circuit board is easily damaged due to vibration or dropping, making it difficult to continue using the entire microphone, greatly increasing the cost.
