Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a ceiling-mounted microphone that is easy to install. Background Technology

[0002] A microphone, also known as a monitoring head, is a device used to collect ambient sound and transmit it to backend equipment. It consists of a microphone and an audio amplifier circuit. Microphones are generally divided into digital microphones and analog microphones. A digital microphone is a sound sensing device that uses a digital signal processing system to convert analog audio signals into digital signals and perform corresponding digital signal processing.

[0003] There are many types of microphones, one of which is the ceiling-mounted microphone. Existing ceiling-mounted microphones are generally fixed directly to the ceiling with screws. Installation requires tools, and installation and replacement are relatively troublesome, so there is room for improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a ceiling-mounted microphone that is easy to install. Its advantage lies in the fact that it requires no tools, thus improving the convenience of microphone replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-install ceiling-mounted microphone includes a microphone head and a mounting base. The bottom of the mounting base has a mounting groove, and both inner walls of the mounting groove have mating grooves. A rotating slot with a ring structure is provided in the middle of the inner walls of the mounting groove. The rotating slot communicates with the mating groove. The top of the microphone head is provided with a mounting base, and both sides of the mounting base are provided with mating posts that are adapted to the mating groove. The inner wall of the mounting groove is provided with an electrical contact piece.

[0007] With the above technical solution: when in use, align the mating post on the mounting base with the mating groove on the mounting base and insert it. After the mating post is fully inserted into the mating groove, the mounting base makes contact with the power contact piece to conduct electricity. Rotate the microphone head, and the mating post will enter the rotating slot for locking, thus completing the installation of the microphone without the need for any tools, improving the convenience of microphone replacement.

[0008] The present invention is further provided that the outer walls of the microphone head are provided with anti-slip protrusions, and the cross-section of the anti-slip protrusions is semi-circular.

[0009] The above technical solution, with its anti-slip protrusions, increases the friction between the finger and the microphone head, preventing slippage when rotating the microphone.

[0010] The present invention is further configured such that the anti-slip protrusion is made of rubber.

[0011] Through the above technical solutions, the anti-slip protrusions made of rubber are relatively soft, making it easy to fully conform to the fingers when pressing, thus improving the comfort of operation.

[0012] The present invention is further configured such that sliding grooves are provided on both inner walls of the mounting groove located below the rotating slot, and pressure plates are slidably connected to the inner walls of the sliding grooves. The pressure plates are connected to the bottom inner wall of the mounting groove through a reset spring, and the energized contact piece is mounted on the surface of the pressure plate.

[0013] Through the above technical solution: when the microphone head is inserted into the mounting slot, the mounting base will squeeze the pressure plate. When the pressure plate is squeezed, it will compress the return spring. Under the reaction force of the return spring, the docking post can be firmly attached to the inner wall of the rotating slot, which improves the firmness of the microphone installation.

[0014] The present invention is further provided in that insulating strips are provided on the outer walls of the energized contact piece, and the insulating strips are in the form of a circular ring structure.

[0015] Through the above technical solutions, the insulating strip can insulate the energized contact piece from the pressure plate, preventing leakage when the microphone is energized.

[0016] The present invention is further configured such that the top of the mounting base has an arc-shaped structure.

[0017] The above technical solution, with its arc-shaped top structure, reduces the contact area between the mounting base and the pressure plate, improving the ease of microphone rotation.

[0018] The present invention is further provided with mounting ears on both sides of the mounting base, and mounting holes are provided on the surface of the mounting ears.

[0019] The above technical solution allows for easy and convenient installation of the mounting base on the roof, improving operational ease.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This easy-to-install ceiling-mounted microphone is designed for easy installation. Simply align the mating post on the mounting base with the mating slot on the mounting base and insert it. Once the mating post is fully inserted into the slot, the mounting base will contact the power contact piece to energize the microphone. Rotate the microphone head, and the mating post will enter the rotating slot for engagement, thus completing the microphone installation without the need for any tools, which greatly improves the convenience of microphone replacement.

[0022] 2. This easy-to-install ceiling-mounted microphone, when the microphone head is inserted into the mounting slot, the mounting base will press the pressure plate. When the pressure plate is pressed, it will compress the return spring. Under the reaction force of the return spring, the docking post can be firmly attached to the inner wall of the rotating slot, which improves the stability of the microphone installation.
