A ceiling speaker assembly is disclosed. In one or more embodiments, the ceiling speaker assembly includes a three-dimensional support frame attached to a perforated grille. The support frame is configured with a speaker aperture adjacent to which a speaker is mounted and a port aperture. The speaker aperture and port aperture are configured such that the speaker aperture is in communication with the front of the speaker and the port aperture is in communication with the rear of the speaker. In one or more embodiments, the support frame includes a horn cavity that functions as an acoustical cross-over such that higher frequencies generated by the speaker are emitted primarily through the speaker aperture, and the lower frequencies generated by the speaker are emitted primarily through the port aperture.
The difference between the mentioned invention and the design of the servant, as is clear from the name of the design, is used for assembly, while in the design of the servant, the sound input is done from another device such as LCD or LED and any other audio source.
Today, with the advancement of technology and new communication systems, and on the other hand, the need for information and coordination for better management and expansion of industrial centers, offices, and factories, hospitals, green spaces and parks, systems under the paging network have their place in today's communication. Since in this plan, the wiring band has been removed and the ceiling can be installed more easily, also the connection to the network and the telephone line can be installed in it. If you need paging, it also can convert the amplifier to paging. In such cases, the phone is connected to 4 speaker inputs, which can also be used for paging.
Speakers are always one of the most consumed and integral goods of the audio industry. Speakers come in a variety of sizes and shapes and are used in many applications, including paging and conference systems. The speakers are divided into different groups depending on the type of use at the installation site, one of which is the classification based on the speaker installation location.
Ceiling speakers are installed on the ceiling, which has two sub-groups of built-in and surface. Built-in ceiling speakers are placed inside the false ceiling or Knauf and only their cap is visible after installation, but surface-mounted ceiling speakers, such as surface-mounted sockets, with all the parts placed inside a chamber, are screwed on the ceiling. As a result, the body (depth) of the ceiling speaker will also be visible.
The ceiling speaker is another audio device that follows a very unique and special performance. Due to the interesting functions used in this type of audio equipment, it has become a very popular and lovable product. If you are also very interested in setting up an audio system at home or even at work, using a ceiling speaker can be very convenient for you. The overhead band is a complete audio player with the highest quality, the above overhead band is active and includes Bluetooth, Wi-Fi, a stereo amplifier with new technology.
If the number of ceiling speakers in an audio system increases or the length of the wiring path increases, the ohm ceiling speaker cannot be used because the overall resistance of the speakers will not match the output impedance of the amplifier.
In the design of the voltage ceiling speaker, an impedance matching transformer is used to convert the received voltage signal into an ohmic signal. Voltage ceiling speaker transformer is operated with a voltage of 70 or 100 volts, these transformers have primary winding and a secondary winding that the input voltage signal is installed to the transformer input and the output ohm signal is installed to the internal speaker.
In previous examples, the existing ceiling band was sometimes disconnected and reconnected due to some noise in the environment, and by placing some capacitors on the board, we have reached the highest level of sound clarity. If there is a network connection in a building, company, hospital, subway, public places, or airports on two or three floors, the runways in the building can be controlled simultaneously. If there is a need for a paging system in the environment, it is possible to establish a connection to any input in the band by phone and no longer need a separate paging device.
