Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a ceiling loudspeaker. Background Art

[0002] The speaker is an indispensable part of the audio system. Its main function is to convert electronic signals into sound waveforms so that people can hear various audio contents. The structure and composition of the speaker include the magnetic circuit system: including permanent magnets, core columns and poles, which constitute the magnetic gap of the speaker and provide a magnetic field for the voice coil. Vibration system: also called the voice coil and diaphragm part, the voice coil is usually wound with very thin copper wire and connected to the output end of the driver. When current passes through the voice coil, the voice coil vibrates under the action of force in the magnetic field. The diaphragm is connected to the voice coil and vibrates with the vibration of the voice coil, thereby making sound.

[0003] There are various types of speakers at present. When decorating a room, it is necessary to set up multiple speakers on the ceiling of the room to enrich the sound effect of the room. However, the speakers currently installed on the roof are mostly directly punched and then fixed to the roof plate by fixing bolts. Since the speakers will vibrate when working, during the long-term vibration process, the traditional fixing method is not only easy to cause the fixing bolts of the speaker to be unstable, but also easy to cause the bolts to loosen and cause the entire speaker to fall. Under long-term vibration, it is also easy to cause dust in the bolt hole to fall, and the installation is time-consuming and labor-intensive.

[0004] Therefore, in view of the above problems, a ceiling speaker is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a ceiling speaker. The utility model punches holes in the ceiling on the roof, and then manually moves the vibration-damping rod to put the vibration-damping rods at both ends of the torsion spring into the punched holes. Then the vibration-damping pads at the lower ends of the vibration-damping rods at both ends will abut against the inner wall of the hole. Under the action of the abutment plate abutting against the outer wall of the lower bottom end of the hole, the entire speaker will abut in the hole under the action of the torsion spring, and the vibration generated when the speaker is working will be reduced by the vibration-damping layer and the vibration-damping pad at the inner end of the abutment plate. The installation is convenient and quick, and there is no risk of loosening and dust falling, or even the whole speaker falling off, such as the traditional bolt installation method. The utility model is highly practical.

[0006] The utility model is achieved in this way:

[0007] A ceiling speaker, comprising a speaker body, with a ring of abutting plates provided along the lower edge of the speaker body, and a fixing block fixedly provided on each of the two sides of the speaker body. A torsion spring is fixedly provided on the fixing block, and a damping rod is connected to both ends of the torsion spring. A U-shaped elbow is fixedly provided at the end of the damping rod, and a damping pad is fixedly provided at the top of the U-shaped elbow.

[0008] Furthermore, a Bluetooth unit is fixedly provided inside the speaker body. An audio conversion unit is connected to the Bluetooth unit, and an audio amplification unit is connected to the audio conversion unit. A speaker horn is fixedly provided at the inner end of the speaker body, and the speaker horn is connected to the audio amplification unit. The Bluetooth unit, the audio conversion unit, the audio amplification unit, and the speaker horn are connected to a power management unit.

[0009] It is convenient to input audio signals by connecting to the Bluetooth unit via Bluetooth, then convert them through the audio conversion unit, and finally amplify the audio through the audio amplification unit and play it out through the speaker horn.

[0010] Furthermore, a damping layer is fixedly provided at the upper end of the abutting plate, and the damping layer is made of butyl rubber. The damping pad is made of silicone material. Both the damping layer and the damping pad can damp the vibration generated when the speaker is working.

[0011] Compared with the prior art, the present utility model drills holes in the ceiling on the roof, then manually toggles the damping rod, and places the damping rods at both ends of the torsion spring into the drilled holes. Then, the damping pads at the lower ends of the damping rods at both ends will abut against the bottom plate of the drilled holes on the ceiling. Under the action of the abutting between the abutting plate and the outer wall of the lower end of the bottom plate of the drilled holes on the ceiling, the entire speaker will abut in the hole under the action of the torsion spring, and through the action of the damping layer and the damping pad at the inner end of the abutting plate, the vibration generated when the speaker is working is reduced. The installation is convenient and fast, and there is no risk of loosening, dust falling, or even the entire speaker falling off, such as in the traditional bolt installation method. The present utility model has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS
