Description

Technical Field

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

[0002] Microphone, scientifically known as microphone, is translated from the English word microphone (transmitter), 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, condenser, electret, etc. Most microphones are electret condenser 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 voice recognition. Whether it is a mobile phone, a telephone or a headset, a built-in or external microphone is required for voice calls. Microphones can also be used to record sounds, music and other sound materials, or in meetings and speeches, transmit the speaker's voice to the audience. In performances and performances, microphones are indispensable equipment to amplify the performer's voice and ensure that the audience can hear it clearly.

[0003] Conventional microphones are relatively simple and do not have a fixed display screen. Therefore, the display screen is generally directly soldered to the PCB main board. The display screen is fixed by reserving a small hole in the middle of the PCB board, passing a nut through the small hole and fixing the display screen on the PCB board. Once the microphone is strongly shaken or dropped, the display screen will be damaged. In addition, such a fixed installation method is relatively complicated. After using it for a long time, the display screen will be damaged or unclear, and it is inconvenient to replace the display screen. The display screen is not convenient to replace and disassemble, making it difficult to continue to use the entire microphone and greatly increasing the cost. Utility Model Content

[0005] The technical solution adopted by the utility model to solve its technical problems is: a microphone with a replaceable display screen, comprising a shell and a top cover, the top cover is fixedly arranged on the top surface of the shell, the interior of the shell is connected with a main control circuit board by screws, a limiting structure is fixedly arranged on the top surface of the main control circuit board, a side surface of the limiting structure is provided with a barb portion, an empty groove is formed inside the limiting structure, a display screen is arranged inside the empty groove, and the barb portion is snap-fitted and connected with the display screen.

[0006] Furthermore, a control module is disposed on the surface of the main control circuit board, and control buttons are movably disposed on the surface of the control module.

[0007] Furthermore, connecting rods are fixedly arranged on both sides of the limiting structure, and the control buttons are movably arranged on the connecting rods.

[0008] Furthermore, two antennas of the same length are arranged inside the shell.

[0009] Furthermore, a power interface is fixedly arranged at the bottom of the main control circuit board.

[0010] Furthermore, a fixing base is fixedly provided at the bottom of the shell, and the fixing base is provided with a fixing hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a microphone with a replaceable display screen, and the display screen is snap-connected with the limiting structure through a hook portion, so that the display screen can be conveniently disassembled and replaced. During use, when the display screen is damaged or needs to be updated or upgraded, the user can easily replace it, thereby extending the service life of the microphone and enabling the display screen to be quickly replaced and disassembled.
