The invention provides a sealed combined-type ceiling-mounted radio, and the radio comprises a radio main body and a ceiling plate. The ceiling plate is shaped like a cuboid, and the radio main body is inset at the ceiling plate. The radio main body comprises an outer edge, a rear cover, air holes, a buckle plate, a screw, and a wiring terminal. The lower part of the rear cover is located in the ceiling plate, and other parts of the rear cover is located outside the ceiling plate. The outer edge is disposed at the bottom edge of the rear cover, and makes close contact with the bottom of the ceiling plate. The air holes are symmetrically disposed on a cylindrical side vertical surface of the rear cover. The wiring terminal is disposed in a groove of the top of the rear cover, and is locatedexactly above one air hole. The buckle plates are connected with the rear cover through the screw, and the two buckle plates are symmetrically distributed on the cylindrical side vertical surface ofthe rear cover. According to the invention, the radio solves the problems in the prior art that dust is liable to enter a radio and affects the application effect of the radio.
Description
technical field [0001] The invention relates to the field of broadcast equipment processing and manufacturing, and specifically designs a sealed combined ceiling broadcast. Background technique [0002] At present, most of the indoor ceiling-mounted broadcasts in the market are composed of speakers that pass through the ceiling board and the main part above the ceiling board. The main part is fixed on the ceiling board by a buckle device. combined. Although this structure is easy to install, it has poor airtightness. For rooms with special pressure requirements, there will be a certain amount of ventilation, which cannot maintain a stable pressure. Due to the existence of gaps, dust is easy to enter. Some traditional radios have cooling holes on the upper part of the back shell, and some even have no cooling holes. This situation can easily cause the dust in the technical interlayer to directly enter the room through the ceiling radio, and at the same time affect the servic...
